Some time since, being engaged with the delivery of a course of Lectures on the physical principles and mechanical construction of the prime movers of machinery, I entered into some details regard- ing the circumstances under which the sources of mechanical power exist in Ireland, and took occa- sion to correct the exaggerated ideas usually enter- tained of the disadvantages under which this coun- try labours, in regard to mechanical industry. The discussions, into which I then entered, al- though but collateral, attracted some attention, and I was requested by the Council of the Royal Dublin Society to proceed fiu'ther with those inquiries. Passing beyond the question of mere mechanical industry, I had occasion to examine the relations of the coimtry to the prime materials of the chemical and metallic manufactures, and finally to discuss some important statistical and moral problems, af- fecting the industrial progress of Ireland. A 2 PREFACE. Tliese inquiries inovlved, besides the examina- tion and comparison of the works of various inde- pendent autliors, a great number of series of new mechanical and chemical investigations. For these the materials had to be gradually collected, and I take this opportunity of returning my thanks to the numerous individuals, who kindly, indeed enthu- siastically, in their separate departments, placed spe- cimens and documents at my disposal, without the assistance of whicli it would have been impossil)le for me to proceed. The facts I had thus collected, and the general conclusions to which I had arrived, were embodied in a course of public Lectures on the Sources of Industry which exist in Ireland, delivered by me at the Royal Dublin Society in the commencement of the present year. On the conclusion of the course, the Coiuicil of the Royal Dublin Society expressed their sanction of the general facts and principles therein contained, and requested that I should pre- pare those Lectures for publication. Such is the origin of the present work, in which, however, I have not retained the form of the Lec- tures described above. The discussion of each sub- ject has been rendered more precise, and carried more into numerical detail, than a lecture to a mixed auditory would allow, and many topics which, owing to the limited time of public lectures, were not then noticed, are now treated of in their proper place. In arrangement and extent the work has thus PREFACE. assumed anotlier fonii, but iu no case have I found occasion to correct a statement, or modify any con- clusion, which I had expressed at lecture. It must be understood, that in sanctioning the general principles which I embodied in my course, so far as to call upon me to prepare those Lectures for publication, the Royal Dublin Society only wished to draw public attention to the eminently important subject of the industrial resources of Ire- land, and not to thereby specially adopt all or any of the conclusions to which I have arrived. The various materials for this w^ork have been collected by me as an individual ; all the experimental in- vestigations which were carried on for its illustration, were conducted in my laboratory ; and, therefore, the responsibility of all facts, where no author is quoted, and for all opinions expressed, or conclu- sions drawn, where not otherwise described, rests with myself In a work thus iindertaken and carried out, it is inevitable that many imperfections shall be dis- covered, which more extensive means and greater facilities for investigation should have enabled me to obviate. The subject is, in itself, of siich a na- ture, that the progress of experiment and of inquiry uuist tend continually to modify our existing views, to extend our actual knowledge, and to substitute for the limited observations of our present field, the wider and more exact investigations, which may naturally result from the discussion of the great Tl PREFACE. question of our industiy. In all such cases, tlie first step, though the most difficiilt and the least ac- credited, is still the most essential. In other countries it has been the most anxious care of Government, and of those intrusted with the superintendence of education, to ascertain the na- ture and amount of their means of promoting indus- try, and extending the employment of the people. It is thus that every year sees the Continental na- tions making such giant strides in manufacturing activity. It is thus that the physical disadvantages, which had so long kept them back, are gradually being lessened in importance. If similar zeal and intelligence were manifested in developing the resources of this country, there would be no fear of the result. As circumstances, however, do not admit of this being done, the pi\b- lication of even the short and imperfect sketch, which alone could be drawn up by an unaided in- dividual, may be useful in awakening the attention of those practically engaged upon such subjects, and may lead to more extensive observation, and more detailed inquiry.

In preseuting to tlie Public a Second Edition of " The Industrial Resources of L-eland," I feel it m}^ duty, and certainly it is one peculiarly agreeable to an author, to express my grateful recognition of the kindness with which the work has been re- ceived, and the very favourable judgments which have been pronounced upon it by various competent authorities. I had, indeed, for many years devoted all the time and energy, which an individual could well com- mand, to obtain materials for the discussion of the problem that presented itself to me upon every side, and under various aspects ; the problem of,— what field for ivork does Ireland really present ? I had always found that real progress was effected only by genuine labour. I knew that all that is sound and permanent in England's industrial power grew, not out of oratorical elegancies, but from hard-handed, stern, and persevering work. By such work alone, PREFACE. work of mind and of body, can a people hope to lidvance, and the consideration of what departments of industry presented most prospect of success, and by wliat modes of action that success could be ren- dered most facile and least remote, presented itself to my mind, naturally, as of vast importance. The expression of public opinion regarding the present work has certainly proved that I was not wrong in my general conceptions. The imperfections, and even, perhaps, inaccuracies, almost inevitable in a work embracing so wide a range of subject, have been kindly overlooked by my indulgent critics, who, agreeing with me in the importance of the object, gave it their approval. I did not, however, presume upon this forbearance, but availed myself of every opportunity of adding to the number of the facts, and to the accuracy of the statements which the work contains. The interval which has elapsed since its first publication has been too short to allow of any very material alter- ation, but in a variety of places, which it would be tedious to enumerate, I have inserted additional information, and rendered more definite and precise that already given. In order also to represent to the reader the more important physical features of the coimtry, I have caused to be prepared, to accom- pany this edition, four maps illustrating, 1 . The geological structure of Ireland. 2. The elevation of its surface. 3. The di.-trlbuiiou of bo^'and drainage. 4. Tiic mcan.s of internal intercourse. PREFACE. IX Although not of large size, I believe these maps will be found to supply a good deal of useful gene- ral information. Detailed references to their con- tents will be found in those chapters of the work where the subjects to which they refer are specially discussed. In putting forward the Second Edition of the " Industrial Resources of Ireland," I have done so without pretension of any very material alteration from the former, but still revised and corrected to the present limits of our knowledge. The sub- ject of promoting the development of industry and of industrial knowledge in our country is one that I have taken up, as the steady and well-con- sidered object of my life; yet whilst following out, in the laboratory or the workshop, the inquiries sub- servient to that object, I have felt myself assisted and encouraged in no ordinary degree by the ap- probation which my countrymen of all classes and parties have awarded to a work, which I consider but a preliminary effort.

The question which presents itself almost on the threshold of every industrial enterprise, is that of the amount and cost of the fuel necessary to be consumed in executing the work : B 2 INDUSTRIAL RESOURCES for in tho existing condition of the Arts, it may almost uni- versally be considered, that, directly or indirectly, tho changes which arc to be produced, whether in composition or in form, in the raw materials of any manufacture, are effected by the operation of heat. If we look to any of the various chemical or metallurgic arts, we find the agency of heat necessary to give liquidity to the substances employed, so that they may be run into moulds, or separated from infusible components ; to effect their perfect mixture, or to bring into play those che- mical affinities, by which their constitution may be altered, and new and more valuable products formed. Hence it is im- possible to carry on those branches of industry in localities destitute of fuel : and where this is scarce and high priced, the cost of production of the manufactured article may be so augmented, as to absorb all profit, and render the prosecution of that trade only a source of loss. In a similar manner, al- though not in the same degree, the mechanical arts are in- fluenced by the cost of fuel. In localities where water power is not available, it is necessary to employ steam. To produce any given motion, to spin a certain weight of cotton, or weave any quantity of linen, there is required steam ; to produce the steam, fuel ; and thus the price of fuel regulates effectively the cost of mechanical power. Abundance and cheapness of fuel are hence main ingredients in industrial success. It is for this reason that in England the active manufacturing dis- tricts mark, almost with geological accuracy, the limits of the coal fields. Hence it is easily conceivable, that in attempting to describe the materials which exist for the prosecution of industry in Ireland, the first step must consist in such an ac- count of the sources of fuel at our disposal, as may determine its practical value, its distribution, its nature, its probable cost, and, as far as possible, its abundance. The materials which wo employ as fuel for our domestic and industrial purposes, are all derived from the vegetable king- dom, being either wood of modern growth, or else turf or coal, which are themselves but masses of vegetable matter of an- cient growth, compressed and decomposed until they present th therefore, needless, as in examining the limits of our local deposits, I shall in fact, point out the localities where it is found. It is only useful to remark, that its greatest development is on the southern and eastern coasts of Galway Bay, where, rising from under the great coal formation of the Munster district, it constitutes the rugged mountains of Burren, and forms much of the country between Galway and Sligo, the hilly character of which distin- guishes it so remarkably from the greater flatness of surface of the calp, and of the lower limestone counties of the centre and south. Interposed between the limestone and the true carboniferous beds, there exists a great sandstone deposit, which, from one of the most important uses of its materials, is known as the millstone grit. The relations of this rock are so identified with the coal measures, that the notices of localities are the same for both, and need not be separated. O INDUSTRIAL RESOURCES In the geological map which accompanies the chapter spe- cially devoted to the mineral resources of Ireland, those sub- divisions of the limestone are not individually marked, but may easily be traced by the reader according to the localities de- scribed; the object of the map being only to indicate such important geological features as influence practical industry. The different shadings represent the different systems of rocks, and for distinction sake, the space occupied by the limestone, which is more than one-third of the entire area of the island, has been left unshaded. The coal formations, as marked on the map, include all strata between the limestone and the new red sandstone (Permian). Thus the area occupied by the millstone grit is contained in that of the coal field of Lough Allen. Were these minor fea- tures of the rocky structure represented, the map should be- come so crowded, and its parts so minute, as to be unsuited for general reference, and unintelligible, except to those already conversant with the subject. The coal formation of Ireland consists of a series of sand- stone and slaty rocks, which rest upon the upper limestone, and give an aspect of considerable elevation to the districts. They are seven in number ; of these one is in Leinster, two are in Munster, three in Ulster, and one in Connaught. These districts differ materially in their produce, according as they are situate to the north or to the south of Dublin. Those to the north yield bituminous or flaming coal : those to the south yield only stone coal or anthracite, which burns without flame. There is no doubt but that this difference results from the geo- logical circumstances of those portions of the island, but it would not suit our purpose to enter into that question. We will commence the history of our coal districts with that of Leinster. This deposit occupies the greater portion of the county of Kilkenny, of the Queen's County, and part of Carlow. It is bounded on the east, west, and south, by two great rivers, the Barrow and the Nore, which run immediately at the base of the Colliery Hills. Its general appearance, when viewed from a distance, is that of a very steep ridge of high land running OF IRELAND. 9 in a direct line for many miles, rising from 800 to 1000 feet above its base, and apparently flat on the summit. It presents this character on every side, but, when viewed from the emi- nence itself, it resembles a barren table land rising precipitously above a flat and highly cultivated country. This district constitutes a great mineral basin ; its strata consequently incline from the edge towards the centre, the undermost appear on the outer edge, and the uppermost in the interior of the district. The strata consist of beds of slate clay, containing abundant thin veins and nodules of ironstone, compact sandstone, and sandstone slate ; with these are inter- posed beds of fire-clay, and the coal beds, of which there are altogether eight workable, arranged in regular succession. These strata require to be more specially described. Slate clay is usually the most abundant rock of the coal for- mation. It is a dull earthy mineral, which easily divides into thin flakes. It decomposes rapidly when exposed to air ; its colour varies from black to grey ; it is sometimes very hard or even flinty, which especially occurs where it comes into contact with the subjacent limestone. The quantity of ironstone as- sociated with this rock is very large, its composition and uses will be hereafter noticed. The sandstone of the coal formation consists of silicious sand cemented by a paste of lime or clay. It contains numerous vegetable impressions. This sandstone frequently becomes micaceous and slaty, so as to split easily into layers, producing the well-known Carlow flags. The roof of the coal bed is sometimes sandstone, and some- times slate clay. The floor of the bed is generally a clay, lo- cally termed coal seat. This substance is soft and earthy : I shall hereafter describe its composition ; at present I need only mention, that it is equal to the best Stourbridge clay, for all the purposes for which that substance is employed. The beds of coal in the Leinster district are, as already stated, eight in number, distinguished by the following names, arranged in the order of their position from below upwards : 1. The Rossmore foot coal. 2. The first bed of slate coal. 10 INDUSTRIAL RESOURCES 3. The second bed of slate coal. 4. The four foot coal. 5. The second foot coal or Drummagh coal. 6. The first three foot coal. 7. The double seam. 8. The second three foot coal. The seventh and eighth beds, being those lying next the sur- face and easiest worked, have been exhausted ; the sixth bed, or first three foot coal, which for the last century has princi- pally supplied the wants of the surrounding country, is now considered by JMr. Griffith as nearly worked out. The inferior beds have been but little, some not at all touched, and must be the theatre of future mining operations. Of these the most important is the four foot coal, and its description will serve as an example of the rest. The upper part of this bed is composed of five feet five inches of slaty coal (locally termed helves), under which there are three feet of hard coal, containing some sulphur pyrites, then a bed of black slate clay of six inches thick, and lastly one foot of coal, containing a thin bed of kelve near the bottom, making alto- gether, a height of coal, kelve, and slate of ten feet, of which but four feet are solid coal. Mr. Grifiith estimates the area occupied by this coal at 5000 acres (Irish), and as its specific gravity is 1-591, the total quantity of pure solid coal may be calculated at rather more than sixty-three millions of tons. On the average this bed appears to lie about eighty yards below the first three foot bed of coal, and at a depth of from 100 to 140 yards from the surface. Formerly the extraction of the coal was very badly managed. The imperfect methods of drainage obliged many shafts to be abandoned wlien they arrived at a certain depth, a large (pian- tity of coal was left behind, and the amount of labour was ex- cessive. Hence coal was high-priced ; 20s. a ton for coal, and from five to eight shillings for small coal or culm. But since Mr. Griffith's Report, and especially by the exertions of the late Mr. Aher, much progress has been made in introducing a better system. The use of the steam engine for draining has enabled .shafts to be rc-worked that had been totally abandoned. The OF IRELAND. 11 quantity of coal raised is estimated at 120,000 tons per annum, and it is sold at a price of about lis. 6(/. per ton for coal, and 4s. per ton for culm. The chemical and economic qualities of this coal will be de- scribed, when I have noted the geographical circumstances of the remaining anthracite basins. The Tipperary coal field is indeed a portion of that already noticed, being separated from the Kilkenny coal field by a nar- row intervening neck of limestone. It extends about twenty miles in length from Freshford to near Cashel. It is about six miles broad in its widest part ; the towns of Killenaule and of New Birmingham mark its centre. It forms a range of hills from 300 to 600 feet in height, abrupt on the north-western, but sloping on the south-eastern side into the limestone plain. The general nature and arrangement of the strata are the same as have been above described, but they dip at a steeper angle and undulate. Hence the coal lies in deep troughs, from which arises a peculiar mode of working, the shaft being sunk in the centre of the trough, and the coal wrought by working upwards on both sides of it. This district appears to contain but three beds of coal. The lowest is but nine inches, the others are each two feet thick. Th quantity of coal at present raised has been estimated at 50,000 tons per annum. The price at which it is at present sold may be estimated at 12s. per ton for good coal, and 4s. per ton for culm. Proceeding further to the south and west, we arrive finally at what is peculiarly termed the Munster coal field. This tract, the most extensive development of the coal strata in the British Empire, occupies considerable portions of the counties of Clare, Limerick, Cork, and Kerry. In all four counties coal has been discovered, and coal mines worked. The physical features of the country are similar to those described in the Tipperary district. The coal consequently lies in a series of troughs, the hills usually striking from east to west, and the strata dipping on either side, north and south, at considerable angles, often perpendicular. From this peculiarity of struc- ture, the estimate of the precise condition of the coal becomes 12 INDUSTRIAL RESOURCES difficult. The same beds fi'equontly re-appear in different parts of the country, thrown up by contortions of the strata to tlie surface, and might then, on supcrticial observation, be counted as distinct deposits. From Mr. Griffith's investigations it ap- pears, however, that there are six distinct layers of coal. Of these, three of the most valuable, locally known as the bulk- vein, the rock-vein, and the sweet-vein, have been recognizt^d on the opposite sides of three of the undulations. The detailed examination of this district has not, however, been as yet car- ried on to a sufficient extent to enable us to trace the entire arrangement of the strata. The most extensive collieries at present worked in this dis- trict are situate in the barony of Duhallow in the county of Cork. The beds of culm present themselves in numerous places over the west coast of Clare, and along the estuary of the Shannon. The beds, although thus of enormous superficial extent, are unfortunately not thick ; the coal is softer and more slaty than in the Tipperary and Kilkenny districts. This ap- plies, however, only to the thinner beds ; the veins mentioned above in Duhallow, and which are from two to three feet in thickness, produce an excellent anthracite, of which some ana- lyses shall be hereafter given. Such are the beds of non-flaming coal or anthracite which occur in Ireland. We shall now pass to the description of the coal of the northern portions of the country, which is bitumi- nous coal. A small but highly-interesting coal field occurs in Tyrone. The country round it resembles a great geological museum, containing rocks of every epoch, from the granite rising from beneath all, to those tertiary clays which constitute the latest term of the geological series, and of which, in relation to the stores of fuel they contain, I shall soon have occasion to speak. The limestone of Dungannon may be considered as forming the base of the Tyrone coal district. It is covered by strata of sandstone, limestone, and slate clay, with clay ironstone, fire- clay, and coal. The external character of the country is simi- lar to that of the southern coal (icjld ; it is an assemblage of low hills, with steci) .leelivitios and llaltened summits. Hero, OF IRELAND. 13 however, when the hills exceed a couple of hundred feet in height, they are capped with new red sandstone or trap, or even with both. This district is geographically subdivided into the Coal-island and the Anahone basins, the former of which is by much the larger and the more important. The Tyrone coal burns rapidly with flame, and evolves great heat : its composition and economic power will be hereafter noticed. The sandstone and slate are generally analogous to those rocks in other coal fields, and need not be further no- ticed. The ironstone and fire-clay will be specially described further on. The linear dimensions of the Coal-island field are six miles by two ; its area about 7000 acres. The Anahone district con- tains only 320 acres, yet recognized, but it may extend under the new red sandstone through a much larger area. Notwithstanding the smallness of this basin, its strata are so much contorted and disturbed, as to cause great irregularity in the workings by changes of level, and the occasional disap- pearance of the bed of coal from amongst the broken strata. Slips and shifts of the layers of rocks also occur, and rather more frequently than in other coal fields. But notwithstand- ing these drawbacks, this basin merits special attention. The coal is excellent : it is not difficult to raise, and its quantity is such as to be capable of diffusing the blessings of industrial prosperity over an extensive area. From Mr. Griffith's Report, it appears that there are in this basin six workable beds of coal. The names of these beds, and their usual thickness, are as follows : BEDS OF COAL. THICKNESS. Ft. In. Ft. In. 1. Annagher coal, 8 to 10 2. Yard coal, 2 0,, 3 3. Braghaveel coal, ....49,, 50 4. Balteboy coal, 9,, 3 3. Derry coal, 46,, 50 G. Gortnaskea coal, ....20,, 60 22 ,, 32 14 INDUSTRIAL RESOURCES From 22 to 32 feet of solid workable coal is thus found within a depth of 120 fathoms, and it is remarked by Mr. Griffith that amongst the numberless pits of the English coal fields, there is no example of the same thickness of coal within the same dis- tance from the surface. The collieries in this district are worked, some by the Hibernian INlining Company, and some by private companies of persons belonging to the neighbourhood. The industry of the latter has been and is profitable. The works of the former have hitherto been carried on at a loss. Whence comes this difference ? The materials for answering this question may present themselves in a subsequent portion of this work. The Anahone coal strata occupy a mineral trough about a mile in length, and a half a mile in breadth. It is bounded on the north by the carboniferous limestone, but on the other sides it is met by the new red sandstone which lies over the coal measures. The deepest pit sunk in it was to fifty-seven yards, and there were found three beds of coal, one of three feet, one of nine feet, and the lowest of two feet in thickness. In some parts of the field certain other beds have been noticed ; the only one actually worked was that of nine feet, and this appears to have been nearly exhausted. It is an excellent coal, and bears carriage without breaking. The working of this basin has been carried only to the limits of the coal strata on the surface, but there is no doubt but that the beds penetrate under the new red sandstone, and probably to a considerable extent. Investigations, under that point of view, still remain to be made, and deserve attention. At the northern extremity of Antrim is found a coal district, unimportant as to magnitude, but remarkable from its associa- tion with the great basaltic mass from which the characteristic scenery of Fairhead and the Causeway is derived. This coal field differs from all the others in this country in wanting the under- lying limestone, and resting directly on mica slate. In this, certainly very rare peculiarity, it is not, however, without pa- rallel ; the coal district of St. Etienne in France being similarly OF IRELAND. 15 circumstanced. The face of the precipices to the sea, where sufficiently IVoe from the debris of the basaltic rock, presents sections of this coal formation which fully illustrate its struc- ture. At top the entire is covered by from 50 to 100 feet of the columnar greenstone, which spreads over the entire district. Under this are beds of reddish sandstone, slate, and coal. At Murlougb Bay, the beds of coal are six in number, of which four are bituminous and two anthracitous. The latter are found, one immediately above, and the other close below a range of columnar basalt of seventy feet in thickness, which lies in amongst the coal strata. It might hence appear that these beds also had been originally bituminous, and that the basalt injected at an intense heat had distilled off their volatile por- tions, converting the residue into anthracite. There are, how- ever, other and strong reasons against such an idea. Thus the beds of coal which lie close under the upper range of basalt are fully bituminous, and the effects of heat shewn where trap dykes traverse the bituminous beds, and convert them into true coke, is quite different from anything visible in the lower beds, which consist of a real anthracite. The quantity of coal which remains in this district is so small, that further detail concerning it is unnecessary. It ap- pears to have been the oldest worked colliei-y in Ireland, per- haps in the empire, as during the year 1770 the miners broke into an old gallery, the walls of which were lined with stalac- tites, evidently of great age, and antique mining tools were found therein. The residents in the district had never heard of a tradition of the mine having been anciently worked, and the excavation must have been made at a very remote period indeed. The bituminous beds of coal are each about two feet six inches thick. The upper bed of anthracite is also of the same thickness : this latter appears, however, to be impure and sulphurous. In Monaghan a small coal basin rests on a patch of the car- boniferous limestone which is insulated within the slate dis- trict. The strata dip at so large an angle as to render the working very difficult ; and as no beds exceeding twelve to 16 INDUSTRIAL RESOURCES . fourteen inches in thickness have been found, this coal district need not be considered as of any value. We arrive now at the last of the coal fields of this country, the Connaught district. It is one worthy of attention from its peculiar geographical position, and from the circumstances connected with the attempts made to establish the manufacture of iron within its bounds. Those attempts, part of the history of the too notorious Arigna Company, shall be treated of here- after. The localities of the coal only need occupy us now. The Shannon, the largest river in the British Islands, rises in the centre of the Connaught coal field, and falls into the Atlantic Ocean: dividing the counties of Clare and Kerry, and cutting through the centre of the Munster coal formation. Expanding in its inland course into a chain of extensive lakes, it intersects, through a line of 247 miles, some of the richest lands in Ireland, washing the banks of ten of the thirty-two counties of which our island is made up. It has its origin in the recesses of the Leitrim hills, where it springs almost with its full power from a vast gulf, the depth of which has not been yet ascertained, and almost immediately expanding forms Lough Allen, of which the area is 8900 acres. The picture of this district, as I saw it some two years since, has never left my mind. The dark brown hills, heather clad, rose abruptly from the water, excepting towards the south, where they were separated from the lake by level spaces of marshy bog. The patches of cultivation, small and rare, far from relieving the aspect of the scene, served but to render its dreariness more oppressive. The lake, smooth as a mirror, reflected the bril- liant sky of midsummer. No wave disturbed it : the noise and bustle of active industry were far away. The melan- choly solitude of my walk was only broken by the approach of some wretched men, who had heard of the piienomeiion of a stranger's presence in their wilds, and pressed around, asking whether I was about to do anything for the country, to give employment. Alas ! it was not in my power. As I walked on, there lay around my path masses of iron ore, equally rich with the best employed in England. I knew that in those hills, whose desolate aspect weighed upon my mind, there were OF IRELAND. 17 concealed all the materials for successful industry. A popula- tion starving, and eager to be employed at any price; a dis- trict capable of setting them at work, if its resources were directed by honesty and common sense ; but all sacrificed to the stock-jobbing speculations of a few men acting on the gross ignorance and credulity of some others. If the industrial cir- cumstances of this country were really known, such events as the jobbing of the Arigna Company could not have occurred. Let us hope that by the progress which science and education have since made, and are now making, the occurrence of aught similar may be for the future prevented. The hills which surround Lough Allen form the Connaught coal field ; they occupy large parts of the counties of Roscom- mon, Sligo, Leitrim, and a portion of Cavan in Ulster. The greatest length of the district is sixteen miles, which is also its greatest breadth. The total area is about one hundred and fourteen thousand Irish aci'es. Seen from the south, they present a steep and straight ridge of from 1000 to 1200 feet in height ; the summits flat, and usually covered with bog. The centre of this district is occupied by Lough Allen. The cir- cuit of the lake may be conveniently divided into four parts, with respect to its content in coal. The rocks are similar to those of the other coal fields : they consist of sandstone, sand- stone slate, slate clay, clay ironstone, and fine fire clay. The strata are very regularly arranged, conformably to the lime- stone on which they rest, and contrary to the declivity of the hill. Slips occur, as in all coal fields ; they do not present any- thing peculiar here. West of Lough Allen the River Arigna divides the field into the southern and western portions. The former consists of one great mountain ridge named Brahlieve : at its base are the Arigna Iron Works. The western division extends be- tween the Arigna and Dorobally rivers. These two portions have almost the same internal structure. Upon the limestone rests slate clay, in thickness from 300 to 600 feet. This rock is remarkable for the rich beds of ironstone which it contains. These ai-e exposed in the channel of the River Arigna in incre- dible numbers. Higher up occur numerous beds of sandstone, 18 INDUSTRIAL RESOURCES and noxt, the fire clay, which, as in the Leinster district, forms the seat of the coal. The beds of coal found in this district are three in number, and were first described with detail in Mr. Griffith's Report on the Connaught coal formation. As the extent and character of these beds of coal will be found of high importance, and that opinions differ regarding them, I shall transcribe in full, the most important of Mr. Griffith's observations. " Of the first Bed of Coal. — The fire clay is succeeded by a bed of coal, which varies in thickness from one to three feet : it is known in the country by the name of the crorv coal. It contains numerous thin laminaj of black slate clay, which render it of little value, except for burning lime. When first brought to the surface it is moderately solid, but on exposure to the air it soon divides into thin flakes. " This bed has never been wrought. If it were, I have little doubt its average thickness would be found to amount to three feet, but it has never been seen excepting at the outgoing. In the vale of the Arigna, near the iron works, where the fire clay was wrought, this coal was three feet thick. This coal runs parallel to the three foot coal which lies above it, and its out- going may be traced along the face of the hills through the greater part of the southern and western division of the dis- trict. " Of the three Foot Coal. — The future prosperity of the Con- naught coal district may be said to depend entirely on the pro- duce of this bed, which, though of moderate thickness, is fortunately of great extent. Its quality as fuel for domestic purposes is excellent, and if used for smelting iron, it is among the best in the empire. According to the analysis of Kirwan, 100 grains are composed of 71 '42, carbon. 23*37, mixture of asphalt and maltha. 5*21, grey ashes. "Specific gravity, 1-351. " The thickness of this coal is rarely less than three feet, or more than three feet four inches. " In its outgoing, commencing at the iron works, it may bo OF IRELAND. 19 traced without difficulty along the northern face of Brahlieve mountain, without any material interruption, for four miles and a^half, by Aughabehy colliery, nearly to Geeva point in the coun- ty of Sligo, and from thence back again on the opposite side of the hill to Tullylions colliery, and afterwards round the eastern end of the mountain to the point above the Arigna works. "In the western division of the district the extent of coal is not so great as in the southern. This division may contain about 1200 acres of the three foot coal, which, added to 2800 acres contained in the southern division, make a general total of about 4000 acres. "From this calculation we should deduct one-fifth part to allow for impurities in the coal and the loss occasioned by slips and undulations. This, at the rate of 7840 tons per acre, will leave upwards of thirty millions of tons of coal as the probable quantity which may be raised out of the southern and western divisions of the district. " The third bed of Coal varies from eight to nine inches in thickness. It is the uppermost bed of coal in the district, and has not been met with except in the southern division." On the three foot coal several collieries are worked. Of these the Rover and the Aughabehy are the principal : the former are situated very near the iron works, the latter farther distant. Coal from the Celtnaveena and from the Meenashama pits will also be found amongst those of which the composition will be given farther on. These coal beds being at a higher level than the general surface of the coimtry, admit of being worked under the most favourable circumstances. The expense of raising the coal is very small ; Mr. Griffith calculated that the cost of it at the pit's mouth was four shillings per ton, and when the iron works were in operation, it was contracted for at five shillings per ton. At the time that Mr. Griffith visited the locality and reported on it, the collieries were in such a wretched condition, flooded with water, their machinery out of repair, and the persons engaged about them so ignorant, that complete accuracy in the information he obtained could not be expected, and it would c2 20 INDUSTRIAL RESOURCES appear that the results above given require some alteration. 1 shall, therefore, in order to indicate as fully as possible the special circumstances of the district, detail, though briefly, the results of examinations of certain portions of it, made by mining engineers, none of whom, however, it must be re- marked, inquired into the general structure of the locality, as Sir. Griffith did, nor were any of them in that position which would justify equal authority being attributed to their indivi- dual reports. After the first exposure of its extraordinary proceedings, when it became indispensable to pay some attention to its pro- per business, the Arigna Iron Company commissioned Mr. Twigg of Chesterfield, a person practically conversant with collieries and iron works, to examine their holdings in this district, and he made several Reports on the subject, of which a very excellent digest has appeared in the Survey of Roscom- mon, published by Mr. Weld. From Mr. Twigg's Reports it would appear, that the bed of coal, as it sinks into the mountain, rather diminishes in thick- ness. He found it in the chisel pit at Aughabchy two feet seven inches thick. Mr. Weld found it in a pit which he exa- mined to be less than two feet. Mr. Twigg estimated the working coal ground at Aughabehy at 160 English acres, and that at an average of 2550 tons per acre it should yield 408,000 tons of coal. The working area of the Rover colliery he valued at from 80 to 100 English aci-es. Mr. Twigg made no survey of the general area of coal in the district, such as that made by Mr. Griffith (4000 Irish acres). In 1823 the Mining Company of Ireland instituted some in- quiries as to the conditions of a portion of this coal field, and had Reports prepared by mining engineers of reputation, for access to which documents, I am indebted to the kindness of Mr. Purdy. The coal bods on Mounterkenny Hill were found by Mr. Kenneth to consist of two distinct patches, that to the north containing 204^, and that more southerly 106 Irish acres of coal. No workings were carried on in the larger, but Tul- lynaha colliery is situated in the smaller portion. In this pit, which was twenty-two yards deep, and very badly worked, he OF IRELAND. 21 found the coal but 20 inches thick, consisting of twelve inches of head coal, 2f inches of slaty coal, and 5^ inches of crow coal. The coal was then laid on the bank for 4§. 6d. per ton, but he considered that, by proper workings, it could be done for 3s. or 3s. 6d. Mr. Kenneth calculates the total quantity of coal in the Mounterkenny part of the field as follows : the north portion, containing 204^ acres, averaging two feet thick, gives House coal, . . 667,897 tons. Slaty coal, . . 400,820 ,, The south portion, 106 acres, same thickness, House coal, . . 345,869 tons. Slaty coal, . . 207,564 ,, making a total of 1,622, 150 tons, of which, however, a third must be subtracted, to allow for loss in actual working for sale. Mr. Geddes, examining the Tvdlynaha pit almost at the same period, reported that it shewed two beds of coal, the upper, or crow coal, three feet thick, the second, eight yards lower, two feet thick : the latter coal, which was of superior quality, was the only bed worked. The field being basin- shaped, a fitting, sunk forty-four yards in the centre, drained the entire. Owing to bad management, the coal then cost 5s. 6d. per ton, but, he says, it could be raised for 3s. id. to the bank, and paying 9d. royalty, and Is. carriage, could be placed on quay at Lough Allen for 5s. Id. per ton. The mountains, which form the northern portion of this dis- trict, do not pi'esent such favourable pictures as that last de- scribed. The thick beds of coal have not as yet been traced upon them, and indeed some featm-es in their structure render it improbable that they exist ; several thinner beds have, how- ever, been found ; and a further examination is desirable. The eastern portion of the district, separated from the last by the River Owenmore, consists of one mountain group, Slieve-a-Nie- ran (the Iron Mountain). Its structure and stratification differ only in detail from that of the southern and western portions, and it contains also three beds of coal, of which the superficial extent is very great. The total thickness of the coal is less, however, and the strata are more broken. It has not been 22 INDUSTRIAL RESOURCES much workod. Indeed for a long time the southern and western divisions will fully suffice for all industrial wants. Such ai'e the circumstances of the coal Held of Lough Allen. Although subsequent examination has sobered down the ex- pectations of its produce which were once held, it must still be considered as capable of becoming an important centre of in- dustry for the interior of this country. The causes which led to the failure of the iron manufacture at Arigna might have acted as forcibly in Staffordshire or at Merthyr. Those causes may be removed. The quantity of coal available is certainly sufficiently great for domestic trade, and it must be recol- lected, that on the surface of the hills which surround Lough Allen, there is a supply of fuel, probably not inferior to that which is contained within them. I have mentioned already that Mr. Griffith considers his original estimate of thirty mil- lions of tons as too high. An estimate given in the Report of the Railway Commissioners in 1838, may probably be consi- dered as embodying all accurate observations made. The Lough Allen district is there stated to contain 20,000 acres of coal, equal to twenty millions tons. At present there is very little coal raised. The quantity does not exceed 3000 tons per annum. Having described the geographical and geological condi- tions of the coal fields of Ireland, I shall now proceed to trace the composition of the coals they yield, and ascertain how far they are adapted for use. To represent their constitution I have given in every case the practical analysis, which shews the quantity of gas given off at a red heat, and that of the coke produced ; the actual weight of coke being the sum of the ashes and of the pure coke. The heating power of each fuel was experimentally determined, and in most instances the elementary analysis has been executed. The minute quantity of nitrogen which exists in all ordi- nary varieties of fuel was not separately determined in those analyses, as it does not exercise any influence on their indus- trial value. Its amount is therefore in all cases included in the number given for the quantity of oxygen present in the specimen of fuel analysed. OF IRELAND. 23 COAL OF THE CONNAUGHT BASIN. This coal is described by Mr. Griffith as intermediate to the open-burning or quick-blazing coal of Scotland and the caking coal of Whitehaven. Mr. Twigg called it a coking coal of good quality. I have foimd it moderately bituminous, bui*ning with flame, and leaving a white ash in moderate quantity. Its only disagreeable character was a great degree of friability, I have submitted to accurate examination four kinds of it, transmitted to me through the kindness of Colonel Jones, Mem- ber of the Shannon Commission. I shall describe the results which I obtained. AUGHABEHY COAL. A rich black coal, easily broken. Its specific gravity 1 "274. When heated it gives off a good deal of inflammable gas, and leaves a light, porous, gi'ey, coherent coke. Analysed in this way it was foimd to give from 100 parts : Volatile matter, 23-10 Pure coke, 66-15 Ashes, 10-73 100-00 Its economic value as a fuel was determined by measuring the quantity of oxygen it was capable of absorbing on ignition with litharge. One part of it reduced twenty-six parts of lead to the metallic state ; 100 parts of it, therefore, represent seventy-seven parts of pure carbon. CELTNAVEENA AND MEENASHAMA COAL. These two coals are almost identical in external appearance. Their specific gravities about 1-290; when ignited they give off inflammable gas, but do not froth ; they produce a mode- rately dense coke^ and leave, when burned away, white ashes. Their analysis was found to be, in 100 parts : CELTNAVEENA. MEENASHAMA. Volatile matter, 19-10 18-90 Pure Coke 6587 61-46 Ashes, 15-03 19-64 : 100-00 100-00 24 INDUSTRIAL RESOURCES Ignited witli litharge, one part of Celtnaveena coal gave twenty-six of lead, and one part of Meenashama coal twenty- five of lead. Hence, 100 parts of Celtnaveena coal corresponded to seventy-seven, and of Meenashama to seventy-three of pure carbon. ROVER COAL. This coal is rather brown in aspect, and has a remarkable tendency to split into cubical fragments. Its specific gravity is 1*287. When ignited it gives out gas, but does not froth. Its coke is porous, slightly coherent. It contains less foreign matter than any of the other kinds. On analysis, its composi- tion was found to be Volatile matter, 17 '70 Pure Coke, 74-89 Ashes, 7-41 100-00 One part of it gave, by ignition with litharge, 28-4 parts of lead, hence 100 parts of the coal con'espond to 84 of pure carbon. The pi'ices of these coals, as given in a notice attached to the specimens, are Rover coal, 4s. 9d. per ton. Meenashama, 5 6 ,, Celtnaveena, 5 6 ,, Aughabehy, 6 4 ,, The Aughabehy and the Rover coal being the most important of this district, I thought it interesting, in addition to the more practical kind of analysis given above, to determine their actual elemental composition, which I found to be as follows : AUGHABEHY. ROVER. Carbon 79-69 8104 Hydrogen, 6-24 4-91 Oxygen, 3-32 6-64 Ashes, 10-75 7-41 10000 100-00 It is thus .seen, that the Aughabehy is a much more bitumi- OF IRELAND. 25 nous coal than the Rover, which approaches nearer in its cha- racter to the anthracites of the south. I do not know whether in the geological relations of the district there is anything capable of explaining the fact. The Celtnaveena and Meena- shama coals have an intermediate quality. COAL OF THE TYRONE BASIN. This coal burns rapidly, and gives out intense heat. It cakes but little, and strongly resembles Ayrshire coal. My colleague, Mr. Davy, examined the Braghaveel coal from Coal Island, and the Kingarrow coal of Dungannon. The former had specific gravity of 1"266, and gave 65*9 per cent, of coke containing 29'4. The latter had specific gravity of 1-307, and gave 66'9 per cent, of coke, containing 37*0 of ashes. The following analyses by myself give the composition and pro- perties of specimens of coal from the new Drumglass colliery, and from the pits of Messrs. Caulfield at Coal Island. COAL FROM DRUMGLASS NEW COLLIERY. It is brilliant, black, friable, frequently mixed with the pyrites, which oxidize on exposure to the air ; its ashes conse- quently usually reddish. On ignition it gives off much gas, froths, and gives a light porous coke. It was found to be composed of. Volatile matter, 48-70 Pure coke, 34-00 Brown ashes, 17*30 100-00 One part of it gave with litharge 22 parts of lead, hence 100 parts correspond to 65 parts of pure carbon. COAL FROM THE COAL ISLAND PITS. This coal has a slaty structure, is dull coloured, but tolera- bly pui'e. Its specific gravity is 1 -267 ; when ignited it gives off much gas, tumesces, and leaves a very porous coke. Its practical analysis gave, Volatile matter, 38-96 Pure coke, 49-39 White ashes, 11-63 100-00 2f) INDUSTRIAL RESOURCES It is, therefore, much purer than the Drumglass coal. One part of it gave, with litharge, 26"5 of lead ; hence 100 parts correspond to 78 of pure carbon. To illustrate further the composition of the coal of this basin, its ultimate constitution was determined : it was as follows : Carbon, 69-08 Hydrogen 586 Oxygen, 13-41 Ashes, 11-65 100-00 COAL OF THE ANTRIM DISTRICT. I found the coal of Ballycastle dull, black in colour, its spe- cific gravity 1-279. On ignition it gave out much gas, frothed very much, and left a porous coke. It consisted of, Volatile matter, 36"96 Pure coke, 4594 Ashes, 17*10 100-00 One part of it gave 25 of lead ; hence 100 parts of it corres- pond to 71 '4 of pure carbon. Of the economic relations of these coals nothing need be said. They are applicable to every use in industry, to which coal is applied in England. The remaining kind of coal, the anthra- cite of the South of Ireland, will require more consideration in that respect. A remarkable feature in the coal fields of the South of Ire- land is tlie large quantities of iron pyrites which are associ- ated with the coal, and which, evolving sulphurous fimies when burned, renders much of it totally unsuited for domestic use, and even for many purposes in the arts. The thicker beds are, however, free from this objection, and it is to the pure anthracite that I shall apply the follo\\ing observations. The composition of anthracite is very uniform. From its not caking or burning with flame it is very generally termed mineral charcoal, and considered to be pure carbon mixed only with ashes. Hence its composition is generally expressed as OF IRELAND. 27 in the following instances. Mr. GrifSth, in his valable Report on the Leinster district, gives the composition of the FIRST BED OF SLATE COAL. Carbon, 92 Ashes, 8 100 FOUR FOOT COAL. Carbon, 96-25 Ashes, 3"73 100-00 The specific gravity of the four foot coal was found to be 1-591. What is here termed carbon, is really the whole combustible and volatile material of the coal. This will appear from the following examination of the Ii'ish anthracites which I made for the purposes of this work. The specimens which I analysed were from The Rushes coal. Queen's County, Leinster district. The Pollough coal, Castlecomer, ,, ,, The Sweet-vein, Kanturk, Munster district. The anthracites have no tendency to froth or cake in coking. They give off Uttle or no inflammable gas on being ignited, but usually the masses break up quite small, especially if the heat be suddenly applied. The ashes are almost always red, owing to oxide of iron remaining after the combustion of the pyrites, which the anthracite usually contains. By the practical mode of analysis these coals yielded : RUSHES. POLLOUGH. SWEET-VEIN.

As this sensibly affects the determination of the carbon in the above analyses, I determined the exact quantity in this last coal, and found it to be 6-18 per cent., and hence the true composition of the Pollough coal was : Bisulphurct of iron, 11-58 Ashes without iron, 2-19 Pure anthracite, 86-23 100-lX) The pure anthracite thus considered separate from ashes or sulphur consisted of, RUSHES.

The Rushes maybe considered as representing the usual composition of this kind of coal. The anthracite is thus shewn to be by no means mere mineral carbon ; it contains a sensible quantity of hydrogen and a trace of oxygen. But these elements are not present in such proportion as admit of flame or smoke in burning, or the production of bituminous vapour or gas by distillation at a red heat. This peculiar composition of anthracite affects its use as a fuel in the arts in an important degree, being the source of many advantages and of some defects, which, together with their remedies, it is necessary to describe. In consequence of its density and closeness of texture, anthracite is difficult to burn, except when in large masses, and it conducts heat but slowly. For this reason also it is liable to splinter up into small fragments. These peculiarities are easily accommodated in practice. One much more important to consider arises from the fact that it contains very little volatile combustible ma- terial, but consists almost entirely of dense, solid carbon, and produces, in good draft, a most intense heat, which is, how- ever, almost confined to the immediate neighbourhood of the fire. Thus, if anthracite be used as the fuel under a steam boiler, the heat in the fire-place may become so great, as to melt away the bars of the grate, and to burn out the bottom of the boiler, and yet the air passing into the flues may not be of such temperature as to produce an evaporation by any means economical. In such case we must call in the aid of science to free our fuel from this disadvantage. It is at once done by passing the vapour of water through the mass of red hot anthracite ; the water is decomposed ; its oxygen combines with carbon, and forms carbonic oxide ; its hydrogen is set free. These mixed combustible gases pass into the flues, and inflaming in the excess of air which enters, give a sheet of flame which I have seen to extend for thirty feet under and through a boiler. The anthracite is thus converted into a 30 INDUSTRIAL RESOURCES flaming coal. There is no loss of heat ; there is no gain of lieat either, as some persons have supposed to occur, but the action, beneficial in its result, is to absorb, in the first place, the excessive heat which was doing local injury, and to distri- bute it over the entire surface of the flues, where its maxi- mum of good can be obtained. The principle of this method has been long kno\vn. Its application has been patented in England, but such patents can only stand for the particular mode of applying the watery vapour therein described, if even for so much. Anthracite burning without smoke, and giving an intense though local heat, assimilates itself to coke, the most costly of our fuels, and hence it is interesting to inquire whether it can be used in what is now the principal employ of coke, in the fires of locomotive engines. On this point but little has as yet been experimentally ascertained. In England it is not of much importance; but one trial has been made which gives promise of its being perfectly successful in that use. I extract from the Mining Journal, quoting a Report to the Directors of the Liverpool and Manchester Railway. " In the first instance the engine ran out with a load about six miles, and the coal was found to do very good duty, with- out any difficulty being experienced either with the tubes or the getting up of the fires. The engine brought back a load of coal waggons from the Heyton Colliery, and acquired, thus loaded, a speed of twenty-one miles an hour. Another trial was made in the evening with the same engine for the whole distance to Manchester, taking five loaded waggons. The journey was accomplished in an hour and twenty-five minutes. The consumption of anthracite was only 5i cwt., although a large portion was wasted, from the fire bars being too wide apart for the economical use of this fuel. The engine would have used upwards of 7^ cwt. of coke for the same journey with the same load." Should tliis result be confirmed by experiments continued for a longer time, it may exercise important influence on the rail- way economy of this country. OF IRELAND. 31 The heating power of anthracite is very great. I have found, and my results confirm those of Berthier, that it is capable of reducing to the metallic state, from 28 to 32 times its weight of lead. Pure carbon gives 35 parts of lead. The bituminous fuels give from 25 to 30. Now the economic value of a fuel, the quantity of water it can boil, or the quantity of iron it can melt, will be found proportional to these numbers, and hence, where the other conditions are rendered suitable for the employ- ment of anthracite, it must be considered one of the best fuels. Before entering on the history of our coal strata, I noticed some of the more ancient rocks on which they rest, and which I shall fully describe when examining the circumstances of our metallic veins. Above the coal formation, there are also ex- tensive series of rocks, the new red sandstone, the oolite, the lias, and the chalk, which occupy in England large portions of the surface, but with us are developed only in the north-eastern corner of the island, forming the County Antrim and part of Derry, and overtopped by these masses of igneous rocks, the trap, and basalt, which chiefly characterize the locality. Some details of special industrial applications of these rocks may hereafter require notice, but I shall now pass from them in order to describe a very peculiar deposit of fuel, more recent than the coal — the Lignite of Lough Neagh. Encompassing the southern half of the lake from Washing Bay in Tyrone, to Sandy Bay in Antrim, this deposit consists of alternations of white, brown, and bluish clay, with white sand and beds of lignite or wood-coal ; and, on the margin of the lough, of the silicified wood for which that lake is so celebrated. In some parts of this deposit the lignite is so abundant, that pits are sunk to raise it when other fuel is scarce. The vast quantity of lignite may be judged from a boring at Sandy Bay, described by Mr. Griffith. In seventy-six feet of depth there occurred three beds of lignite, one of twenty, one of twenty-five, and one of fifteen feet thick, giving a total thickness of strata of fuel of sixty feet; the remaining sixteen feet were clay. Else- where the beds of lignite are not so much developed, but as the area of this tertiary basin extends over one hundred square 32 INDUSTRIAL RESOURCES miles, the quantity of fuel therein contained may be considered of much public interest. The clays of this basin are analogous to those of Bovey, where pipe-clay is obtained, along with lig- nite : whether good pipe-clay can be had in the basin of Lough Neagh has not as yet been tried. The lignite has been already described as intermediate be- tween wood and coal. This is shewn in its composition, given in the following analyses from this distinct. The lignites examined retained all the structm-e of wood, and were of a deep brown colour. ^Vhen ignited they gave off gaseous matter, which burned brilliantly, and left a dense black charcoal. In this way they were foimd constituted of, No. 1. No. 2. Volatile matter, 57-70 53-70 Pure charcoal, 33-66 3009 Ashes, 8-64 16-21 100-00 100-00 By ignition with lithai-ge.. No. 1 gave 19-6 times its weight of lead, and No. 2 gave 16-7 times its weight. Hence, 100 parts of No. 1, correspond to 58 of pure carbon, 100 „ No. 2, „ „ 50 Their elementary composition was found to be as follows : No. 1. No. 2. Carbon, 58-56 51-36 Hydrogen 5-95 7-35 Oxygen, 26-85 25-08 Ashes, 8-64 16-21 100-00 100-00 The economic value of the lignite appears from those analy- ses about two-thirds that of average coal. The heat which it produces is more diffused than that from coal, and less intense. Indeed in all respects as to application to industrial uses, the position of lignite is between those of coal and wood. The last of our sources of fuel that I shall proceed to de- scribe, is of comparatively modern formation, and is considered most specially characteristic of this island; it is our turf. Our OF IRELAND, 33 bogs may become, under the influence of an enlightened energy, sources of industry eminently productive. It is a fuel of ex- cellent nature. We see it in ordinary use spoiled by its mode of preparation. It is here my duty to point out how it can be properly prepared, and economically used. Its importance to Ireland will, I trust, justify me in entering into some detail as to its nature, its composition, and its preparation. The ex- cessive moisture of this climate, and the tendency to the growth of certain mosses, are the primary causes of bogs. The process of their formation is well described by Captain Portlock, in the Memoir of the Ordnance Survey of Londonderry : " In the production of bog, sphagnum is allowed on all hands to have been a principal agent, and superabundant moisture the inducing cause. To account for such moisture, various opinions have been advanced, more especially that of the de- struction of large forests, which, by obstructing in their fall the usual channels of drainage, were supposed to have caused an accumulation of water. That opinion, however, cannot be supported, — for, as Mr. Aher remarks in the ' Bog Reports,' ' such trees as are found have generally six or seven feet of compact peat under their roots, which are found standing as they grew, evidently proving the formation of peat to have been previous to the growth of the trees' — a fact, which, in relation to firs, may be verified in probably every bog in this parish, turf from three to five feet thick undei-lying the lowest layer of such trees. It is, indeed, so strongly marked in the bog, which on the Donegal side bounds the road to Muff, that the turf-cutters, having arrived at the last depth of turf, find timber no longer, though formerly it was abundant, as is proved by their own testimony from experience, and by the few scattered stumps which still remain resting on the present sur- face. Not so, however, with oaks, as their stumps are commonly found resting on the gravel at the base, or on the sides of the small hillocks of gravel and sand, which so often stud the sur- faces of bogs, and have by Mr. Aher been aptly called 'islands.' He further adds, that in the counties of Tipperary, Kilkenny, &c., they are popularly called ' derries,' — a name deserving D 34 INDUSTRIAL UESOURCES attention, whether viewed as expressive of the existing fact, or as resulting- from a lingering traditionary remembrance of their former condition, when, crowned with oaks, they were dis- tinguishable from the dense forest of firs, skirting the marshy plains around them. The strong resemblance to ancient water- courses of the valleys and basins which now contain bog, and the occurrence of marl and shells at the bottoms of many, na- turally suggest the idea of shallow lakes, — a view of the sub- ject adopted in the ' Bog Reports,' by Messrs. Nimmo and Griffith. Such lakes may have originated in the natural ine- qualities of the ground, — or been formed by the choking-up of channels of drainage by heaps of clay and gravel — or they may have been reduced to the necessary state of shallowness by the gradual wearing away of obstacles which had dammed up and retained their waters at a higher level. Mr. Nimmo describes the mode in which the basin of a bog has been banked in by the alluvial deposits of a river (during freshets), and, in a similar manner, numerous examples might be adduced of bogs separated by banks of clay and gravel, owing to rivers running at their base, and below their level. " In some cases also clay, which is so frequently found spread over gravel at the bottom of bogs, has produced a kind of pud- dle, which, by retaining the waters of floods or springs, has facilitated the formation of muddy pools. '• Inall such cases the process may be thus stated : — A shal- low pool induced and favoured the vegetation of aquatic plants, which gradually crejit in from the borders towards the deeper centre. Mud accumulated round their roots and stalks, and a spongy, semi-fluid mass was thus formed, Avell fitted for the growth of moss, which now, especially sphapium, began to luxuriate : this, absorbing a large quantity of water, and con- tinuing to shoot out new plants above, while the old were de- caying, rotting, and compressing into a solid substance below, gradually replaced the water by a mass of vegetable matter. In this manner the marsh might be filled up, while tlie central, or moister portion, continuing to excite a more rapid growth of the moss, it would be gradually raised above the edges, OF IRELAND. 35 until the whole siu'face had attained an elevation sufficient to discharge the surface water by existing channels of drainage, and calculated by its slope to facilitate their jjassage, when a limit would be in some degree set to its further increase. Springs existing under the bog, or in its immediate vicinity, might indeed still favour its growth, though in a decreasing ratio ; and here — if the water proceeding from them were so obstructed as to accumulate at its base, and to keep it in a rotten, fluid state — the surface of the bog might be ultimately so raised, and its continuity below so totally destroyed, as to cause it to flow over the retaining obstacle, and flood the adjacent country. ' ' In mountain districts the progress of the phenomenon is similar. Pools, indeed, cannot in so many instances be formed, the steep slopes facilitating drainage, — but the clouds and mists, resting on the summits and sides of mountains, amply supply their surface with moisture, which comes too in the most favom-able form for vegetation — not in a sudden torrent, but unceasingly and gently, drop by drop. The extent of such bogs is also affected by the nature of the rock below them. On quartz they are shallow and small ; on any rock yielding by its decomposition a clayey coating, they are considerable — the thickness of the bog, for example, on Knocklaid, in the county of Antrim, which is 1685 feet high, being near twelve feet. The summit bogs of high mountains are distinguishable from those of lower levels, by the total absence of large trees." The total area of Ii'eland is twenty millions of acres. The total area of bog is estimated at 2,830,000 acres; nearly one- seventh of the entire sm'face of the island. Of these bogs there are 1,576,000 acres of flat bog ; the remaining 1,254,000 acres are mountain bog. The former is spread over the cen- tral portions of the great limestone plain ; the latter is princi- pally distributed through the hilly country which ranges along the coast. In an industrial point of view, it is the central dis- trict of bogs which deserves attention. Some special circum- stances which affect certain localities may require considera- tion in a different point of view ; at present the subject must d2 36 INDUSTRIAL RESOURCES be consiilcrcd mider its general relations as to the constitution and application of this fuel. All idea of the amount of area occupied by bog, and of its geographical distribution, sufficiently exact for the general consideration of industrial problems, may be deduced from the accompanying map, in which the localities and extent of the larger bogs, surveyed by the Bog Commissioners, have been laid down. It will be seen that the district west of the Shannon contains by far the greatest proportion, and that a chain of bog passes almost from Dublin to that river through the cen- tral counties. In Leitrim, Kerry, and in Antrim, there is also a large extent of bog. This map does not include such small patches of bog as are scattered through various parts of Ire- land, but which, although useful as sources of fuel to the inha- bitants of the district, are totally without interest with regard to industry. As turf includes a mass of plants in different stages of decomposition, its aspect and constitution vary very much. Near the surface it is light coloured, spongy, and contains the vegetable remains but little altered. Deeper, it is brown, denser, and more decomposed ; and finally, at the base of the greater bogs, some of which present a depth of forty feet, the mass of turf assumes the black colour, and nearly the density of coal, to which also it approximates very much in chemical composition. The amount of ash contained in turf is also variable, and appears to increase in proportion as we descend. Thus in the section of a bog forty feet deep at Timahoe, those portions near the surface contained 1^ per cent, of ashes; the central portions 3^ per cent., whilst the lowest four feet of turf contained 19 per cent, of ashes. In the superficial layers it may also be remarked, that the composition is nearly the same as that of wood, the vegetable material being but little altered; and in the lower we find the change into coal nearly complete. Notwithstanding these extreme variations, we may yet esta- blish the ordinary constitution of turf with certainty enough for practical use, and on the average specimens of turf selected from various localities, the following results have been ob- tained. OF IRELAND. 37 Turf, in Ireland, is usually sold by measure, not by weight, and as our results refer to weight, it is necessary, in compar- ing cost, to ascertain the density of average turf, as sold. The specific gravity of the light surface turf is about 400, water being 1000, and from this it increases, with the compactness of the structure, to nearly the density of coal. A cubic yard of good turf, packed close in sods, weighs about 9001b. The densest turf well packed will go so far as llOOlb per cubic yard ; but the light turf, of which so much is burned, may not weigh more than 500tb. The density of the turf, which these numbers illustrate, affect many of its technical uses, as shall be hereafter shewn. For comparison I may mention, that the cubic yard of solid coal weighs nearly a ton ; but the coal in fragments, as sold and burned, weighs but 13 cwt. per cubic yard : it fs, therefore, about twice as dense as average turf. Furnaces, to burn the same weight of coal and turf, should re- quire double the capacity for the latter. By means of the following analytical results, the general practical qualities and the chemical composition of turf may be considered to be established. The specimens were selected from Cappoge in Kildare, and Kilbeggan in Westmeath, on different sides of the great Bog of Allen, and from Kilbaha in Clare, where an extensive district of bog exists. When ignited, the turf gives off inflammable gas, much wa- ter, and leaves a light, easily combustible charcoal. I found the specimens analyzed to yield. LIGHT TURF. DENSE TURF. CAPPOGE. KILBEGGAN.

Hence the liquor obtained in distilling turf contains no free ammonia. On the contrary it is acid from acetic acid, but even of this it yields so little that it cannot become, as occurs in the case of wood, an object of manufacture. The calorific power of dry turf is about half that of coal. It yields, when ignited with litharge, about fourteen times its weight of lead. This power is, however, immensely diminished in ordinary use by the water which is allowed to remain in its texture, and of which the spongy character of its mass renders it very difficult to get rid. There is nothing in the industrial economy of this country which requires more alteration than the collection and preparation of our turf. Indeed I may say, that for practical purposes, this valuable fuel is absolutely spoiled, as it is now prepared. It is cut in a wet season of the year ; whilst drying, it is exposed to the weather ; it hence is in reality not dried at all. It is very usual to find the turf of commerce containing one- fourth of its weight of water ; al- though it then feels dry to the hand : but let us examine how that affects its calorific power. One pound of pure, dry turf will evaporate six pounds of water ; now in one pound of turf, as usually found, there are three-quarters of a pound of dry turf, and oncvquartcr of a pound of water. The three-quarters of a pound can only evaporate four jiounds and one-half of wa- OF IRELAND. 39 ter. But out of this it must first evaporate the quarter of a pound contained in its mass, and hence the water boiled away by one pound of such turf is reduced to four poiuids and a quar- ter. The loss is here 30 per cent. ; a proportion which makes all the difference between a good fuel and one almost unfit for use. When turf is dried in the air, under cover, it still retains one-tenth of its weight of water, which reduces its calorific power 12 per cent. ; one pound of such turf evaporating five and one-third pounds of water. This effect is sufficient, how- ever, for the great majority of objects. The further desicca- tion is too expensive and too troublesome to be used, except in some especial cases, of which the more important shall be here- after noticed. The characteristic fault of turf as a fuel is its want of den- sity, which renders it difficult to concentrate within a limited space the quantity pf heat necessary for many operations. The manner of heating of turf is, indeed, just the opposite to that of anthracite. The turf yields a vast body of volatile inflam- mable ingredients, which pass into the flues and chimney, and thus distribute the heat of combustion over a great space, whilst in no one point is the heat intense. Hence for all flaming- fires, turf is applicable ; and in its application to boilers it is peculiarly useful, as there is no liability to that burning away of the metal, which may arise from the local intensity of the heat of coke or coal. If it be required, it is quite possible, however, to obtain a very intense heat with turf, as I shall no- tice when speaking of the manufacture of iron. I have already noticed the area over which turf may become available for industry. It comprises the central limestone plain, extending also over Galway and Mayo, with parts of Clare and Kerry, The cost at which turf may be con- sumed in the immediate neighbourhood of the bogs, I consider to be, from pretty numerous inquiries, not above 3s. 6d. per ton, but in our subsequent calculations I shall take 4s., in order that the error, if any, may be in excess of cost. I shall consider, however, that the turf is dried in the air un- der cover, which, if our industry ever becomes active, and our fuel economized, must be the ordinary practice. Its economic 40 INDUSTRIAL RESOURCES value may then be practically assumed as 44 per cent, of that of ordinary coal. The turf at 4s. per ton costs as much to give a certain heat as coal at 9s. Id. The removal of the porosity and elasticity of turf, so that it may assume the solidity of coal, has been the object of many experimenters, who have proposed mechanical and other pro- cesses for the purpose. Amongst those we may mention Lord Willougby D'Eresby, whose anxiety to improve the condition of the industrial classes deserves the highest praise. Lately with us I\Lr. Charles Wye Williams has brought into use va- rious preparations of turf, and has given considerable impulse to the utilization of this kind of fuel. It has been found, that the elasticity of the turf fibre presents great obstacles to com- pression : and the black turf which is not fibrous, is of itself sufficiently dense. The only modes that present promise of successful issue, are those invented by Mr. Williams. One of these consists in drying the turf well, and then impregnating it with tar, which renders it waterproof, as it were, besides augmenting its calorific power. Turf so prepared has no ten- dency to re-absorb moisture, which is the serious failing of turf that has been perfectly dried, and the expense of thus bitumenizing the turf is, I understand, very trifling. It is said to be manufactured for from (is. to 8s. per ton, and from the trials that have been made with it upon a very considerable scale, it appears to have a calorific power little inferior to coal. All of those machines which have been invented for pressing turf, sod after sod, by manual labour, become ultimately too expensive to allow of their being profitably used. It is only by operating on a great scale, and with powerful machinery, in fact, only by manufacturing compressed peat largely for sale, that the operation can be made to succeed practically. This is what Mr. Charles W. Williams has so well effected at Cappoge. The turf, when fresh cut, has its fibre broken up as far as possible, and is then placed between cloths, and pi'essed by a hydraulic press of great power. The condensation is to about one-third of the volume, and it loses about two- fifths of its weight, by the water, which is forced out in the pressing, and subsei^iuently dried out. The sods of turf so OF IRELAND. 41 prepared, even when formed of the very upper and spongiest stratum of the turf, are denser than wood. They have little or no tendency to grow damp, and it is found that including all labour, wear and tear, and original cost, this compressed peat can be delivered at the works for 5s. per ton. When this compressed peat is carbonized it gives a fine coherent coke, which contains very little ash, and amounts to about 30 per cent, of its Aveight, when the coking is properly carried on. The density of this coke is greater than that of wood charcoal, being found to range from 913 to 1040; the turf from which it was made having a specific gravity of from 910 to 1160. Its cost when manufactiu*ed does not exceed 20s. per ton. The employment of turf as a source of heat in industry is extending ; already it supplies exclusively the steam boats on the Shannon and a great number of distilleries and mills. From the numerical facts that have been given, the economy of its use may be inferred and compared with that of other fuels. Not merely may we utilize turf in its natural condition, or compressed, or impregnated with pitchy matter, but we may carbonize it as we do wood, and prepare turf charcoal, the pro- perties of which it is important to establish. The methods of carbonization are of two kinds. 1. By heating the turf in close vessels ; by this mode loss is avoided, but it is expensive, and there is no compensation in the distilled liquors, which do not contain acetic acid in any quantity. The tar is often small in quantity, and the gases are deficient in illuminating power. Hence the charcoal is the only valuable product. Its quantity varies from 30 to 40 per cent, by weight of the dry turf. The products of the distillation of 1 137ft> of turf, were found by Blavier to be : 4741b charcoal or . . 41 "1 per cent. 2261b watery liquor or . 19*3 ,, 7tb tar or ... . 6 ,, 430tb gaseous matter or 39'0 ,, 1157 100-0 The quantity of tar is very variable; thus the turf used in 42 INDUSTRIAL RESOURCES the iron furnaces at Voitoumra gives, when coked in close vessels : Charcoal, 40-23 Tar, 24-50 Watery liquor, 14"00 Gaseous matter, 21 "25 100 -00 The economical cai'bonization of turf is best carried on in heaps, in the same manner as that of wood. The sods must be regularly arranged, and laid as close as possible : they are the better of being large, fifteen inches long by six broad and five deep. The heaps, built hemispherically, should be smaller in size than the heaps of wood usually are. In general 5000 or 6000 large sods may go to a heap, which will thus contain 1500 cubic feet. The mass must be allowed to heat more than is necessary for wood, and the process requires to be very care- fully attended to, from the extreme combustibility of the char- coal. The quantity of charcoal obtained in this mode of car- bonization is from 25 to 30 per cent, of the weight of the dry turf. The charcoal so obtained is light and very inflammable. It possesses nearly the volume of the tm"f. It usually burns with a light flame, as the volatile matters are not totally expelled. This is she\\Ti by the composition of a specimen analysed with the following result : Carbon, 89-90 Hydrogen, 1-70 Oxygen and nitrogen, 4-20 Ashes 4-20 100-00 This charcoal is usually very light and friable. It is hence peculiarly fitted for the manufacture of gunpowder, and Mr. Derust, Pyrotechnist to Vauxhall, who experimented with it at the request of Mr. Williams, reported that it stood the several tests, and was 20 per cent, more combustible than wood charcoal. OV IRELAND. 43 For many industrial uses, the charcoal so prepared is too light, as, generally speaking, it is only vnth fuels of consider- able density that the most intense heat can be produced ; but by coking compressed turf, it has been already shewn, that the resulting charcoal may attain a density of 1040, which is far superior to that of wood charcoal, and even equal to that of the best coke from coal. The importance of this result in the metallurgic relations of this fuel I shall hereafter notice. As to calorific effect, turf charcoal is about the same as coal cokes and little inferior to wood charcoal. This is shewn in the table, page 47, and it has been found to give from twenty- six to thirty parts of lead by its reducing action upon litharge. It is peculiarly important in the preparation of the charcoal from turf, that the material should be selected as free as pos- sible from earthy impurities, for all such are concentrated in the coke, which may be thereby rendered of little comparative value. This is remarkably shewn by observing the composi- tion of the coke from the four varieties of turf, the analyses of which are given in page 34. Thus the cokes consisted in 100 parts of LIGHT TURF.

This latter quantity might altogether unfit it for practical purposes. Such is the description of om* sources of fuel, as far as I have been able to collect facts regarding them. I have been anxious to remove exaggerated ideas of opposite characters which have been entertained. Although destitute of the grand de- velopment of mineral fuel which has rendered the sister king- dom the centre of the industrial arts, we yet possess several coal districts of considerable extent, and yielding large supplies of fuel, and moreover, there is in our bogs amassed a quantity 44 INDUSTRIAL RESOURCES of turf, which, if the peculiar characters of that fuel be suita- bly attended to, may become of eminent importance to the country. All the applications of fuel depend, however, on its cost, and the amount and consequences of the cost of fuel in Ireland shall form the next subject of inquiry. OF lUKLAND. 45 CHAPTER II.

FINAL CONCLUSION AS TO HOW FAR THE COST OF FUEL NECESSARILY AFFECTS INDUS- TRY IN IRELAND. ELEMENTS OF CALCULATION FOR EVAPO- RATIVE STEAM POWER. The distribution, amount, and composition of the fuels of Ireland having been described so far as information could be obtained upon the subject, it remains to examine the cost at which by their means the more important mechanical opera- tions can be effected. It is possible that to some, who are already habituated to the consideration of such topics, the details, with the discussion of which the present chapter will be occupied, may appear unnecessary, as such persons, knowing the price of fuel as already given, may follow out from their own experience all the practical consequences of importance to which it leads. But comparatively few persons are in so favourable a position. Misconceptions of very varied, but of serious character, are entertained of the degree in which the price of fuel influences 46 INDUSTRIAL RESOURCES the industrial arts, and it is of great importance to remove those erroneous impressions. I shall, therefore, endeavoui* to exhibit, in as definite a form as the nature of the subject ad- mits, the degree in which the price of fuel is an element in the cost of the final products of manufacture, and to illustrate the mode in which the greatest economy can be secm'ed in its ap- plication. In giving motion to machinery, fuel does not act directly, but through the medium of water, which when heated is con- verted into vapour, increasing enormously in bulk, and exer- cising a pressure on the containing vessel which is capable of overcoming the greatest resistance, provided the heat be sup- plied to a sufficient extent. It is thus that the steam engine, that wonderful creation of the highest mechanical genius, transfers the power originally resident in the fuel to the most remote elements of a complicated system of machinery. The power transferred is, generally speaking, proportional to the fuel burned, and thus the cost of power identifies itself for the most part with the cost of fuel. It is not my purpose to de- scribe the steam engine. There are published special works in which all the details of its history and construction are given, but in order that the question of fuels may be placed in a proper point of view, it is necessary to notice some of the more important features of its action. In the complete steam engine there are two distinct parts, which involve totally difterent scientific conditions. The mo- tive agent is a certain bulk of steam. Now the first problem in working the engine is to generate that bulk of steam with the least possible expense, and the second is, having obtained the steam, to apply it under the mechanical conditions most favourable for its final result. According to the degree of at- tention to these points is the ultimate cost of power, audit is hence absolutely necessary for us to endeavour to realize them. The unit of power assumed in all mechanical questions in these countries is the horse power. The word does not now by any means signify the actual work a horse could do, but is understood to mean a force sufficient to elevate 33,000lh of OF IRELAND, 47 water one foot per minute. That is about 884 tons of water raised one foot in an hour. Now as the increase of water in bulk when converted into steam at the ordinary boiling point is just 1700 times, and that its pressure is then I5tb on each square inch, this force of a horse power will be brought into play when water is vaporized at the rate of 0'54 of a cubic foot per hour ; very little more than half a cubic foot. This makes no allowance for loss of fuel, friction of machinery, &c. It is the purely theoretical result, to which all practical results must be applied as to a measure of their economy. We shall now proceed to examine some of the results of practice, pm*- sued according to various methods, which shall be thereby contrasted. From an extensive series of trials made by Peclet, Parkes, and others, we may deduce the following numbers as express- ing the absolute heating power of fuels, and as they will be of frequent reference I shall insert them here. One pound of each fuel evaporates in pounds of water : Hydrogen, .... 46-8 Average coal, . . . 120 Pure charcoal, . . . 14"6 Best turf, .... 6-0 Coke, 13-0 Dry wood, .... T'O Best turf coke, . . 12*8 Wood not dried, . . 5*2 The economic value of coal is so well determined by the ex- perience of English engineers, that I shall hereafter assume their results without going into any detail, but as the use of turf is still a subject of doubt and discussion in this country, I shall notice some examples of its present employment, and endeavom* to deduce from them its economy. It may be easily understood that the evidence collected is not from England ; the superabundance of coal there causes a neglect of all other fuels, and it will hence be necessary for us in this, as in many other instances, to take our examples from countries equally unfortunate with ourselves, where the paucity and dearness of fuel render its economy important, and where the high state of scientific education renders their results satisfactory and attainable. The numbers given above, as to the evaporative power of 48 INDUSTRIAL RESOURCES coals, are for the usual bituminous coals, represented in tliis country by those of the Loujj;h Allen basin which are the least, and those of Tyrone which are the most bituminous. As so much of the coal of Ireland is anthracitous, and as this variety has been but very little employed in practice in England, it will be useful, as more firmly establishing the grounds of future conclusions, to notice what the practical results of its use have been in some cases where accurate numbers have been record- ed. Dr. Fyfe in Edinburgh published the results of some ex- periments which he carried on to compare the evaporative power of the anthracite with that of bituminous coal. The re- sult was, that with the same furnace lib anthracite evaporated 7*94tt) of water, whilst the coal evaporated G-62. The compo- sition of the two he found to be : ANTHRACITE. BITUMINOUS COAL. Moisture, 4*3 7"3 Volatile matter, . . . 13-3 34-3 Fixed carbon, .... 71 "4 30"3 Ashes, 10-8 7-3 100-0 100-0 Dr. Fyfe concluded from his experiments, which were con- tinued for a long time, and were very carefully conducted, that in any fuel the heating power is proportional to the quan- tity of fixed carbon, that is, pure coke, which the fuel yields. This would make the practical value of anthracite about one and a half times that of ordinary bituminous coal. This, how- ever, can occur only where the volatile parts of the coal are not well burned, as certainly occurred in Dr. Fyfe's experi- ment. It has been shewn that average coal will evaporate, when perfectly consumed, and the heat perfectly economized, twelve times its weight of water. The heating effect of anthracite is too local to allow of its being fully utilized if merely burned on an ordinary grate, but if the flaming character be given to it by means of a current of steam in the manner described in page 29, the economy of heat is much increased, although its ab- solute amount is not altered. In experiments carried on with OF IRELAND, 4^ an anthracite furnace, of which the furnace bars dipped in water troughs, and thus fui'nished steam to the fuel as patented by Mr. Kymer, it was found that in an engine boiler work- ing under twenty-eight pounds pressure to the square inch, lljtt) of anthracite evaporated lllStb of water, that is, one pound to nine pounds and a half. It is hence evident that the anthracite is at least fully as effective as the average bitumi- nous coal, and consequently in future it is not necessary to make any distinction between them under this point of view. One of the most eminent mechanical engineers of the present day, Mr. Scott Russell, has given the following as the working conditions of the evaporation of water and generation of power. One cubic foot of water evaporated per hour, is a horse power. lllb of coals evaporate a cubic foot of water. lib of coals evaporates 6*6tb of water. Here the quantity of water necessary to generate a horse power of steam, is nearly double the purely theoretical result, and the quantity of coal necessary to evaporate the water is also nearly double that which has been indicated (page 47), as the proper duty of average coal. This enormous difference originates in the peculiar construction of the most usual form of steam boilers, which, having been invented in a country rich in fuel, and where its economy was, then at least, unim- portant, produces a waste of the source of power very neces- sary for us to avoid. If you enter the engine house of a factory in Lancashire or Lanark, unless it be of quite novel and peculiar construction, you will observe the steam boiler to be of that kind so well named waggon-shaped; under it are situated great fires, the flues from which winding round the boiler pass into a chimney, from the aperture of which are emitted vast volumes of dense black smoke. The fire-man has but two cares, to keep his boiler full of water, and his fire-place full of coals. These he throws in with astonishing good will ; they are so cheap. In these waggon boilers the relation which the heated portion of the boiler bears to its entire surface seldom exceeds one-half; and 50 INDUSTRIAL RESOURCES it has boen found by ]\Ir. Parkes, from experimrnts of a very precise character, that with such boilers the highest evapora- tive effect that can be obtained is 8"86lb of water for one pound of coals. In those districts where fuel is so cheap, the waste is often even greater ; thus Mr. Parkes values the ave- rage consumption of the best engines in Manchester at one hundred and a half of coals per horse power per day; that is fourteen pounds per hour. We may consider, therefore, that with the common waggon boiler, and ordinarj' steam engine, the horse power is represented by a cubic foot of water evapo- rated per hour, and that this requires the combustion of at least ten pounds of coals. We in Ireland are not by any means the only people who are badly off for fuel. In one of the most industrious districts of England, in Cornwall, in the midst of its mineral wealth, there is want of fuel for steam power to drain the mines. The en- gineers in Cornwall, therefore, could not shovel in coals like their brethren in the North. They had the problem distinctly set before them, — how much work can be got out of a bushel of coals ? and certainly their residts have been surprising. The facts were denied for a long time by the Lancashire en- gine makers ; the reports of duty of the Cornish engines were quoted as a mechanical romance ; but that is now all past, and as our condition is nearly the same as that of the Cornish men, I shall describe what they have effected. In place of the waggon boiler already noticed, there is used a long cylindrical boiler, perforated by one, two, or even three flues; so that, although on a greater scale, it is not very un- like the tubular boiler of a locomotive engine. Sometimes the fire-place is in the centre flue, at others, under the boiler. The flue passes also round the boiler, so that a far greater sur- face of water, in proportion to its mass, is presented to the action of the heat than in the waggon form. The result is found to be, that, by Mr. Parkcs's trials, one pound of coal in a Cornish boiler will evaporate twelve pounds of water, thus fully giving the result I have taken as the standard. The eva- poration of a cubic foot of water from a Cornish boiler should take 5-2lb of coal ; little more than one-half of what the waggon OF IRELAND. 51 boiler in average requires, even when well worked. Henee, where fuel is dear thei'e should be no question of waggon boil- ers. The manufacturer who burns two pounds of coal where one pound should be sufficient, pays twice as much as is neces- sai-y for his power, which must of course be deducted from his profits. But the improvements in the Cornish steam engine are not restricted to a better construction of the boiler. Another is still more remarkable, inasmuch as its principle is much more latent. We have seen that to generate the steam, the elastic force of which represents the horse power, we must evaporate 0'54 cubic foot of water. Now this weighs 33^lb, and, avoid- ing minute fractions, we may consider that it might be eva- porated in a Cornish boiler by three pounds of coal. In place of fourteen pounds as given by Parkes, or eleven pounds as taken by Scott Russell, for practice, the theoretical result be- comes three pounds. This, however, allows no loss for fric- tion in machinery ; no loss of motion in transmission through the parts of the engine ; no waste of steam. Yet all these are sources of loss, and nevertheless they are compensated for in the Cornish engine, and a duty or performance obtained in practice, which, when reduced to the horse power, becomes three pounds of coal burned per hour ; and even in some in- stances falls below it, so that the work really done with all friction of machinery, is greater than that indicated by theory without loss or friction. In the ordinary way of working a condensing engine, the steam is let on the piston fully throughout its course, and we may assume the working pressure at lifteen poimds per square inch. This pressure is to be multiplied by the length of the stroke to obtain the effective power. Let us take the stroke at forty-eight inches. The force exerted will therefore be, per square inch, 15 X 48 = 720. Now an engine of forty-eight inch stroke, and consuming the same quantity of steam, is worked differently in Corn- wall. The steam (for example) is generated at a pressure of sixty pounds per square inch, that is of four atmospheres. E 2 52 INDUSTRIAL RESOURCES It is let on thp piston until this has moved through ono-fourth of its stroke, that is through twelve inches. The valve is then closed, and the steam allowed to move the piston by its own elasticity through the remaining space. The steam hence ex- pands so as finally to fill the whole cylinder, and in so doing gradually lessens its elasticity, so that at the end its pressure is fifteen pounds, the same as it was all through in the first ex- ample. Let us calculate what is the difference of result. The working pressure, when the steam enters the cylinder, is sixty pounds, and at that pressure it moves the piston twelve inches. The supply is then cut off; the steam expands to double its volume, and moves the piston through another twelve inches. By expanding, however, it reduces its elasticity to one-half, that is to thirty pounds ; and its mean pressure through this space is to be reckoned at forty-five pounds. Continuing to expand, it moves the piston through another twelve inches, but its pressure is then reduced to twenty pounds, and hence the m an pressure through this portion of its course is twenty-five pounds ; and finally, when the piston has been pushed to the end of the cylinder, and the steam quadrupled in volume, its effective pressure is reduced to fifteen pounds to the square inch, and the mean pressure during the last twelve inches of movement has been seventeen pounds and a half. Now let us sum up these results. The piston moved In first period through 12 inches with a constant pressure of fiOlb ;= 720 In second „ „ 12 „ with an average pressure of -lolb = 540 In third „ „ 12 „ „ „ „ of 251b = 300 In fourth „ „ 12 „ „ „ „ ofl7^1b=210 Total, 1770 which is the measure of the effective power, being two and a half times that given by the same quantity of steam used without the expansive action. These numbers would require small corrections to be made quite accurate ; so great a pres- sure as sixty pounds is also not used in practice, but for the object of popularly illustrating the principle of expansion on which the Cornish engines are worked, it is quite sufficient. The great economy of fuel which is effected in Cornwall, de- pends thus on the form of boiler, and on the use made of the OF IRELAND. 53 steam. These are two points to which our attention must be steadily devoted, for the diffei'ence between burning fourteen pounds of coal per hour, and burning three pounds, is all im- portant in industry. Now it must be remarked here that a fault to which every steam engine is liable, is most developed in the Coi'nish engine, that is, an inequality in the velocity of the piston. In a com- mon engine, the action of the steam being constant tends to give the piston an accelerated velocity, and in the Cornish en- gine, the force of the steam being variable, gives a velocity of piston also variable within wide limits. This is partly ob- viated by the crank and the fly-wheel, the mass of which serves to regulate the motion, but some disadvantage still remains. It affects the application of the steam engine to many delicate operations, and I shall return specially to the subject when I come to speak of another source of industrial power. These explanations regarding boilers and steam engines, Cornish and common, being premised, it is now possible to dis- cuss the question— what is the expense of steam power in Ire- land ? The horse power is to be taken as the unit. The cost of 100 horse power is of course 100 times the cost of one. I have already noticed the prices of coals in the coal fields of Ireland, but I shall give them here in a tabular form for comparison. LARGE COAL. SMALL COAL. Leinster coal field, . . . . lis. 6d. 4s. Od. Tipperary ,, .... 12 40 Tyrone ,, .... 12 j Connaught, ,, from 4s. 9J. to 6 4 Now for generating heat, a mixtm-e in equal parts of large and small coal may be very conveniently burned. Indeed small coal almost alone might be used, but I do not wish to push an ideal economy so far. In the immediate neighbourhood of the pit mouth, therefore, the cost per ton of fuel adapted to all heating pm-poses, may be taken as averaging 8s. per ton. In carriage to a distance, it may be assumed that 3d. per ton per mile is a sufficiently high charge, and taking the radius of sup- 54 INDUSTRIAL RESOliRCES ply of a pit at twenty miles, the price should ]w at the extreme limit 8»-. + (3(/. X 20) := 13.s. per ton. Hence the average price of such coal (mixed large and small) in the district, should be 10s. 6d. per ton, and I shall take it at 12*-. per ton, in order to be on the safe side. It has been shewn that with the waggon boiler and ordinary condensing engine, the horse power of steam is generated by the combustion of ten pounds of coals per hour. This is 120tb per working day of twelve hours. Now as one ton (22401b) costs \2s., 1201b will cost 7^d. Thus, in the interior of the country, within the distance of twenty miles from the coalpits, the cost of fuel for steam power may be taken at 7^d. per horse power per day. None of our coal districts come near enough to the coast to meet the competition of British coal. Round the island, there- fore, and for some ten or twelve miles inland, and also along the course of the navigable rivers, we must consider steam as generated by the combustion of coal brought from England. From this we may except the upper and middle Shannon, which, however, does not influence the result we seek. The price of English, and especially of the Welch and Scotch flaming coals, which answer excellently for industrial purposes, has lately fallen very much in this country, owing principally to the re- duction of ireight from the want of other occupation for a great number of ships, in the recent depressed state of trade. The price may rise somewhat, but not materially, and we may con- sider the average of native coal consumed at 12s. to represent also the price at which furnace coals may be laid in on the eastern coast, and some distance up the rivers which open into it. On the western and southern coast, the cost of carriage should be higher, but not materially to aff^ect the price; for in Limerick, which is the only locality where the question becomes impor- tant, the concurrence of Arigna coal and the abundance of turf would prevent much alteration. I shall hence take the cost of fuel for a horse power as being the same, 7^d. per working day, burning English coal within range of the coast. In the central counties, where the vast turbaries of the lime- stone plain supply abundance of fuel, the cost of it will vary OF IRELAND. 55 very much according to its mode of preparation. I shall put out of question here the compound fuels proposed by Mr. Wil- liams, and even compressed peat; not that I am insensible of their value, but that I am anxious to place the question of cost on the basis most easily realized. I suppose, therefore, that the turf has been only vt^ell dried. In this case its heating power, when perfectly dry, is one-half that of coal. But under ordinary circumstances it retains so much moisture, that it may be practically taken at somewhat more than two-fifths. That this result is founded on sufficient data may be judged from the following evidence. I have been favoured with returns of the work and consump- tion of a condensing engine of thirty-four horse power, which is employed to grind corn in one of our central counties, and imder the boiler of which the turf of the vicinity is buxmed. The result is found to be, that in twelve hours there are con- sumed fifty boxes of 280tb each ; that is, thirty-four pounds of turf per horse power per hour. Now as we may consider a cubic foot (62-3tb) of water evaporated per hour as the mea- sure of a horse power, it results that the turf in this instance does not evaporate quite twice its weight of water. In fact it is used damp ; it is badly managed in the furnace, and I notice it only as an instance of what we shall require to correct. In this mill the box of turf costs 6d., which is just 4s. per ton. The cost of fuel is 9d. per horse power for the day of twelve hours. This we shall hereafter find to be excessive. Mr. Purdy, by whose exertions our mineral industry has been so materially benefited, has furnished me with a note of the performance of turf under a steam engine erected for drain- ing a lead mine at Derrynoos in Armagh, formerly worked by the Mining Company of Ireland. The district is very unfa- vourably circumstanced as to fuel. Coal, whether from Coal- Island or Newry, could arrive only after a land carriage, which alone costs 10s. per ton. The turf was black mountain turf, giving much ash ; its cost, reduced to weight, was 6s. lO^d. per ton. In this the locality was exceptional. The work of the turf was compared with the work of average Cardiff coals in the same engine and under the same circumstances. 56 INDUSTRIAL RESOUUCES lib coal raised 3G5,591tt) water one foot high. 1 ft turf raised 121, 489tb Reduced to the bushel (941b) it becomes : A bushel of coals raised 34,3G5,354tt) water one foot high. A bushel of turf „ ll,419,9GGtt). ,, Hence the effect of the turf is one-third of that of average coal. This was inferior turf, and yet the effect is much greater than in the former case, where much better turf was used. The engine burned per horse poAver per day, twenty-four pounds of turf, and for the day of twelve hours the cost of fuel per horse power was lO^d. Now it must not be forgotten, first, that the fire places of those engines were not constructed for turf but for coal, and that consequently they could not burn turf in a suitable man- ner; and second, that the turf is prepared without suitable desiccation. Hence the proportionally greater cost of power. The high price of fuel in Cornwall has led not only to the wonderful economy produced by the principle of expansion, but also to endeavours to replace the imported coal by the na- tive turf of that district. Mr. Wickstead has given an ac- count of an engine with which comparative trials of these fuels were made. The engine, working five horse power, consumed in twenty- four hours three bushels and one-third of coal (3101b). In the same time and doing the same work it burned three cubic feet of turf, which cost 8^d. I think that in the volume of the turf, an error has crept into Mr. Wickstead's paper, which prevents my estimating the weight of turf consumed, but the cost enables us to judge. At 10s. per ton the coals should cost IJcl., and hence the turf did the same work for just half that price. This result was so decisive, that Mr. Grout, on one of whose engines the trial was made, is getting the fire-places of all his engine boilers altered, that turf may be exclusively burned in them. Mr. Hurstall of Bristol has published the results of his use of turf with a high pressure engine. The steam was of thirty pounds pressure, and there were consumed seventy-four pounds OF IRELAND. 57 of turf (which he describes as bad) per hour. The quantity of water evaporated from the boiler per hour was in average 360R>. The turf consequently evaporated nearly five times its weight of water. This result approximates to what theory leads us to expect, but the turf certainly was not bad, although it is so described by Mr. Burstall. In the factory of Garnier at Beauvais, the tiu-f of Breles is burned under a twenty horse power high pressure engine. This turf is black ; it contains 7 per cent, of ashes, and gives 40 per cent, of coke. The turf necessary was double the weight of the coal previously employed. Its cost was one- fourth. The following results, as to the comparative eifective power of turf and coal, are derived from the working of the Lans- downe, one of the steamers of the Inland Navigation Company which ply upon the Shannon with goods and passengers. They have been kindly placed in my hands for my present object, by Mr. C. W. Williams. Before the use of turf was introduced, there was burned in a week, which comprises forty-nine hours of work, twenty-four tons of coal, which costing in average at Killaloe, 15s. per ton, amount to £18, or 7s. 5d. per hour. To do the same work at present, burning nothing but turf, there are consumed per week 315 boxes of turf, which at Id. per box costs £9 12s. Id,, or 3s. \\d. per hour of work, — but a shade more than half the cost with coal. The engines of the Lansdowne are condensing, of thirty-eight inches and a half diameter, and three feet and a half stroke. The usual velocity is twentj'-five strokes per minute. The box of turf contains twenty cubic feet ; not very closely packed. It weighs about three cwt. and a half; so that the ton weight of turf costs about 3s. Qd. The weight of 315 boxes is hence fifty-five tons and a quarter, and the practical value of the turf is to that of the coal as 24 to 55^, or as 43 to 100. Almost exactly the same as calculated in page 39, from the average composition of good turf. It is interesting to consider the influence which the substitution of turf for coal in the Shannon steamers has on the population residing near its banks. In the year 1839, there was no turf burned, and the coals con- 58 INDUSTRIAL RESOURCES sumed on board the Company's boats amounted to 3108 tons. In 1843 there were burned but 724 tons of coal, although the amount of trade was much increased. The quantity of turf consumed was upwards of 7000 tons, which at 3s. Gd. per ton gives an expenditure of more than £1200 distributed in wages of labour, by which almost the entire cost of the turf is made up. Tlie equivalent quantity of coals would have cost above £1800, so that at the same time the Com2)any saved £600 a year. Those remarkable facts are well exhibited in a letter written by Mr. Williams to the Board of Admiralty, which is subjoined, as it illustrates some additional circumstances. Mr. Williams' estimate of the saving is greater than mine, for in the pre- ceding analysis of the results, I have taken coal at a lower price than is assumed in his letter. The reason is, that it has fallen since those results were obtained, and I have calculated from what the price is, whereas he calculated from what it Avas at the time quoted. (Copy).

" L The Lansdowne, a steamer with two engines, 38|^ inch cylinders, at 3 ft. 6 in. stroke, con- sumed upon an average 120 tons of coal per month, running daily (except Simday) a dis- tance of forty-six miles, at 18s. per ton, co- vering expenses, £108 " The same duty is done with 1419 boxes of turf of twenty cubic feet, about 230 ton weight, at 7d. per box, 417 9 Difference in the cost of the fuel per month, £66 12 3 ' ' 2. The difference in weight is, therefore, as two of turf to one of coal, and on the Shannon the difference in price is less than one-half that of coal. "3. Its proportionate duration may be estimated by the quan- tity required, compared with coal, to perform the same duty, that being double its weight its duration in the fur- nace is half that of coal. "4. From recent experiments with turf in the experimental boiler in the Company's yard at Liverpool, it is found that turf can only be profitably used when it is of the quality that is obtained in good seasons. If bad or damp, its eva- porative power is reduced one-third and more. To improve the evaporative power of this fuel, however, results have shewn, that an addition of 40 per cent, of a preparation of turf by an improved method which I have been engaged upon for some years, will render it cheaper than coal used with bad turf, or than coal burned alone ; and that the same per centage of this prepared fuel added to good turf, greatly increases its evaporative power, with a very tri- fling addition to the cost. "From these facts it is evident that turf may bo used ad- vantageously in localities where it abounds, and where there 60 INDUSTRIAL RESOURCES is an absence of coal. Care, however, must be taken that the furnace bars are lowered, not only to admit a greater bulk of fuel, but also to prevent too great a volume of air passing in the ash-pit, and then through the bars. I may add also, that in burning turf it is highly essential that air be admitted in the air chamber behind the bridge, in consequence of the rapidity with which the gases from this kind of fuel fly off. If it be excluded there upon the common furnace principle, the weight and bulk of fuel will be increased, the evaporative power re- duced, and the cost proportionably greater. " It will give me much pleasui'e to furnish you with any fur- ther information in my power. " I have the honour to be, Sir, "Your obedient, humble Servant, "C. W. Williams. " To Sidney Herbert, Esq., " Admiralty." I have already noticed, that from my own inquiries the best turf may be had in the turf districts for 3s. Qd. per ton, and as it is a fuel that will never be drawn far for any industrial use, we may take 4s. per ton as the practical value of turf well dried within the range of the central counties. At this price, and allowing to it 44 per cent, of the calorific effect of coal, the horse power should cost Gd. per day, that is one-fourth cheaper than coal. Mr. Williams, using the same sort of fuel as is employed at the corn mill noticed page 55, and paying Gd. per box, but drying it well, found that, with a large working waggon boiler, there were 3-871b of water evaporated per pound of turf, and that it cost 3s. Td. to evaporate 100 cubic feet of water. Now this is at the rate of b^d. per horse power per working day. When the turf was burned in the furnace without Mr. Williams' peculiar mode of effecting perfect com- bustion, the cost per horse power was G^d., coinciding with the result which 1 have derived from other sources. From all those examples, it may be decisively concluded, tliat in Ireland the horse power of steam costs per day in fuel : Using coals, whether British or native, l^d. OF IRELAND. 61 Using turf properly dried, .... 6d. Using turf in Mr. Williams' mode, . 5jd. This is when the waggon boiler and the ordinary non-expan- sive engine are employed. Now without entering into details which any person can de- duce from what has been already said, I may lay down the dis- tinct principle, that using the Cornish system, both as to boiler and mode of using the steam, the fuel per horse power is reduced to one half. Therefore the cost in Ireland becomes : With coals for 12 hours, S^d. With turf ,, ,, 3d. That is to say, that any mechanical operation, grinding or sawing, or weaving, spinning, or threshing, or any other, which requires the same labour as to raise 1000 tons of water ten feet high, can be effected in almost any part of Ireland by the consumption of a quantity of coals, costing 3|c/., or by turf, costing 3d. How utterly unimportant is the cost of fuel in these mecha- nical operations ! It may be said, however, that small as this cost is when so described, it becomes very serious when taken for a year of 300 working days, and for an 100 horse engine. It is then found, in fact, that the fuel at 3^d. per horse power per day, costs £484 7s. 6d. per year, and for the other estimates in pro- portion. So that in England, where fuel is very abundant and cheap, the horse power is had for half the money : and thus in the article of coals a difference of £500 a year may exist, ruin- ous to the manufacturer in Ireland. It is necessary to examine how far this can operate. In some parts of Lancashire, coals are sold at the pit mouth for 3s. \0d. or 4s. per ton. About Bury they are from 5s. to 5s. 3c?. In the north of Lancashire they are from 6s. 3d. to 8s. From personal inquiries I am informed that furnace coal is never had in Manchester under 8s., and Dr. Ure, in his Phi- losophy of Manufactures, states facts from whence it results, that he assumes the cost of coal in Manchester to be 12s. 4d. per ton. 62 INDUSTRIAL RESOURCES Mr. Henwood, who has calculated the total quantity of coals raised in Lancashire and their price, gives as the resulting average cost per ton, 10s. ^0d. We may take Lancashire as the example of the other manu- facturing parts of England. In none is coal materially cheaper, and we shall certainly not bo far wrong if we assume as the average price of coal in English industry, two-thirds of what we have assumed for the cost in Ireland, that is two-thirds of 12s., or 8s. per ton. But in order to estimate the cost of a horse power per day, we must see what is done in England. The cheapness of fuel there leads to an excessive waste of it, so that hitherto only in Cornwall was economy attended to ; and even now improve- ment in that respect is but slowly taking place. According to Dr. Ure the consumption of coal in Manchester is twelve pounds per hour ; according to Mr. Parkes it is fourteen pounds per hour. Mr. Fairbairn, in his Report on the Bann Reservoirs, also considers twelve pounds as the usual consump- tion. Mr. Scott Russell's estimate for standard performance is eleven pounds. Now taking as an average twelve pounds, the horse power costs per working day, 6^d. We have seen that by ordinary attention with the waggon boiler, ten pounds per hour suffices, and this in Ireland costs 7^(1- The difference in favour of England from the cheap fuel is therefore but 1| drawing frames. (JOO slubbing spindles. 1,800 roving spindles. Mr. Baynes does not give the number of persons employed in his mill, but from its size it cannot possibly be under 800. Taking Mr. Symons' estimate of wages, 10s. (id., the amount paid weekly in such a mill is £420 ; the cost of coals for power being £20 15s. In Ireland the coals might cost half as much more, but by how much less might the wages be ? In concluding this department of my subject, in which I have probably wearied many of my readers by those columns of figures and per cents., I shall subjoin some numerical illustra- tions taken from Mr. Symons' work already noticed. They exhibit, on the authority of eminent English manufacturers, OF IRELAND. 67 the numerical proportions of outlay in factories such as now occupy us. The cost of erecting a power loom factory of 500 looms, calculated to weave good calico, should be about £18,000. Its annual produce should be 150,000 pieces of twenty-four yards at 6s., £45,000, which cost as under: Interest of capital and wear of machinery, . £1,800 Steam power, oil, tallow, keeping up machi- nery, utensils, &c., 2,000 Yarns and flax, 32,000 Wages to workmen, 7,500 Profit 1,700 £45,000 Probable expense of a spinning cotton mill, with hand-mules to produce No. 40, would be £23,000. With self-actors £2000 more. The produce annually, taking the present prices of cotton, should be £25,000. Cost of which as follows : Interest of capital and wear and tear of ma- chinery £2,300 Cotton, 14,000 Steam power, oil, tallow, gas, and general expense of keeping up utensils and machi- nery, and repair, 1,800 Wages to workmen, 5,400 Profit, 1,500 £25,000 The produce is taken at 10,0001b weekly. Now what is to be considered in these estimates is the fact, that coals, or even steam power altogether, is not an impor- tant item, but is only inserted along with oil and tallow, gas, repairs, &c., all of which together amount in the first instance to 4^ per cent., and in the second to 7'2 per cent, of the value of the products. In order to exhibit the proportion which the cost of fuel f2 68 INDUSTKIAL RESOURCES bears to the other elements of manufacture in Ireland, as well as in the sister kingdom, I have been favoured with the follow- ing return from a factory for spinning and weaving cottons, which is situated near one of the large cities on the eastern coast, and uses coals and cotton, both imported from England. The value of cotton as bought in Liverpool for a year, was £11,177 9s. Gd. The freight and other expenses of carriage to Ireland was £332 5s. The average number of hands em- ployed was 273, and the total amount of wages paid in the year was £4832 8s. The coals consumed were 1669 tons ; of these about one-fifth was for heating and drying purposes, but as this use, although not for steam power, is still for the manufacture, there need not be any distinction drawn. The coals cost rather under \2s. per ton, but that sum may be taken, and hence there was paid for the coals £901. The total value of the manufactured article was £24,099 17s. Now from these data it follows : That the value of t^^e raw material was . 46*4 per cent. The charge on its carriage to Ireland, . 1'4 ,, The wages oflabour, 20-0 The fuel for steam power and for drying and heating, 2*7 >> of the cost of the manu actured article. Now the difference in the cost of fuel is, as has been already shewn, but about 4s. per ton in favour of Lancashire, and this one-third of 2-7 forms not one per cent, of the value of the final product of industry. The average rate of wages paid is found to be Gs. 9d. per week. The average in Lancashire is 10s. 6d. How much more important does this difference appear to be than that of fuel. It is, however, not possible to compare them directly. It is a topic which will require some explanation in a future chapter. Besides the two steam engines of twenty-five horse nominal power, there is on this concern a breast wheel which is em- ployed whenever water is available. It is not large, and could not in any material degree modify the above result. I have, therefore, not taken it at all into account. From all that has been described, I conclude that there is OF IRELAND. 69 no locality in Ireland where fuel for industrial purposes may not be had, either native or imported ; and that the cost of that fuel may not exceed, by more than half, the average cost of fuel in the manufacturing districts of England, and certainly need never be the double. That the cost of fuel to generate steam power bears so small a proportion to the value of the products of mechanical industry, as to be totally unimportant, in comparison with money-wages and raw material, regarding which this country labours certainly under no natural disadvan- tage, and that finally, by attention to the mode of burning fuel and using steam, the difference in price of coal may even in itself be compensated for, and other specially favourable circumstances may be rendered available to the success of in- dustry in Ireland. I have noticed at such length the question of the cost of fuel and of steam power, not from my own opinion of its ultimate importance, but that we might at once break down that barrier to all active exertion, which indolent ignorance constantly re- treats behind. The cry of, " what can we do ? consider Eng- land's coal mines," is answered by shewing that we have avail- able fuel enough. The lament that coals are so dear with us and so cheap in England, is, I trust, set at rest by the evidence of how little influential the price of fuel is. However, there are other sources of power besides coals ; there are other motive powers than steam. Of the 83,000 horse power em- ployed to give motion to mills in England, 21,000, even in the coal districts, are not moved by fire but by water. The force of gravity in falling water can spin and weave as well as the elasticity of steam ; and in this power we are not deficient. It is necessary to study its circumstances in detail, and I shall, therefore, next proceed to discuss the condition of Ireland with regard to water power. In finally passing from the subject of fuel and steam power, I shall subjoin, for convenience of reference, a tabular com- parison of the peculiarities of the ordinary and of the Cornish steam boilers, taken from IMr. Scott Russell's work on the steam engine : 70 INDUSTRIAL RESOURCES CONBITIONS.

To the statement made in this chapter of the cost of power from various sources, it may be added that practical mecha- nists and'engineers habitually value the cost of steam power on the east^of Ireland, within a range of seven or eight miles from the coast, at one shilling per horse power per day, which includes wages, interest, repairs, and every other expenditure, as well as fuel. This estimate fully agrees with that of the cost of fuel deduced from my own results. OF IRELAND. CHAPTER HI. OF THE WATER POWER OF IRELAND. MODE IN WHICH IT ORIGI- NATES.

AD- VANTAGEOUS SITUATION OF MANY POINTS ON THE COAST FOR EMPLOYING THE TIDE AS A SOURCE OF MECHANICAL POWER. The land being placed on the surface of our globe at a level superior to that of the ocean, by which its coasts are washed, there is produced continually, by atmospherical conditions, a circulation of the mass of water, which, evaporating from the 72 INDUSTRIAL RESOURCES surface, ascends as vapour to tbe higher and colder regions of the air, whore it is condensed into clouds. These float until the electrical condition which characterizes their peculiar mo- lecular state being dissipated, they fall as rain, as hail, or snow, and the water thus regaining the solid or liquid form, tends continually by its gravity to a lower level, until it joins the general mass of ocean, from whence it had been originally de- rived. The rain or snow thus falling in the interior and ele- vated districts of the country, forms at first rivulets, then streams, finally rivers, and the force of the descending water is capable of application to give motion to machinery : it is the source, best known and mo*t simply applicable, of water power. If all the water which falls upon the surface of a country, as rain, passed regularly to the sea, and that the average height through which it passed, as well as its weight, were capable of being determined, it should be a simple problem to calculate the entire mechanical force thus brought into play. But there is no country in which these data are absolutely known ; with us, at least, such inquiries are but in their infancy ; and al- though the importance of the subject will not allow me to pass from it without endeavouring to obtain at least an approxi- mation to its value, yet I can only discuss in a general point of view the circumstances which affect the water power of this country, and having brought forward the imperfect materials that I have been able to collect, endeavour to excite others to a sense of what still remains to be done. It is but lately that observations of the quantity of rain that falls in Ireland have been made with accuracy over a number of points. Exposed to the first brunt of the Atlantic storms, a vast body of rain is carried to these Islands by the southerly and westerly winds. In average half as much more rain falls in England than on the Continent of Europe. Here there is probably not more actual rain than in England, but there is more damp. Long since Arthur Young noticed the difficulty of drying agricultural produce in this country, and assigned to this humidity the rapid vegetation which clothes our surface with natural herbage, even where there is scarcely a trace of OF IRELAND. 73 soil. It is hence that this island has been called the Emerald set in the ring of the sea. The moistixre of the air in Ireland is thus greater than in England, and the quantity of rain that actually falls is in average certainly not less. The results that have been obtained up to the present time, by various ob- servers, are as follows : In the table are given the name of the observers, the locali- ties, and the mean quantity of rain deduced from observations of a certain number of years. LOCALITY. STATED BY | QUANTITY. 1 AVERAGE OF Dublin, Belfast, Castlecomer, Cork, Cork, Derry, Apjohn, Portlock, Ahcr, Smith, Roy. Inst., Sampson, 30-87 34-96 37-80 40-20 36-03 3112 Six years. Six years. Eighteen years. Six years. Six years. Seven years. It is thus seen that Dublin is one of the dryest, and Cork one of the wettest places where observations have been made. Indeed both here and in England a great difference exists be- tween the quantities of rain which fall on the eastern and west- ern coasts, but our west coast has not hitherto been in such a social condition as admits of consecutive scientific observa- tions. There is no doubt, however, but that the amount of rain falling on the west coast equals the highest number given above (that of Cork) ; and we shall certainly not exceed if we value the average quantity of rain that falls over the entire surface of Ireland at thirty-six inches. If all the rain that falls on the surface of Ireland in a year were collected, it should thus cover the island to the depth of thirty-six inches ; and as the area of Ireland amounts to 20,808,-271 square acres, containing 100,712,631,640 square yards, there are hence this number of cubic yards of water pre- cipitated on the surface of Ireland every year. Of this a quan- tity, which we shall now seek to determine, becomes available 74 INDUSTRIAL RESOURCES for industrial purposes. All this mass of water does not reach the sea. Tlie spontaneous evaporation which is carried on by every point of surface that is not absolutely dry, raises again into the atmosphere a large proportion of it. This proportion is difficult to determine, indeed impossible to determine, with accuracy : it may still be approximated to in the following manner. Mr. Dobson made experiments at Liverpool, to ascertain how much water evaporated in a year from a surface of water, The mean quantity of rain was 37 '48 inches. The mean quan- tity of water evaporated was 36'78. Hence, if there was no dry land the rain and evaporation should balance ; but the soil evaporates much less than a surface of water, and a rocky sur- face or dry ground scarcely evaporates at all. The illustrious Dalton carried on experiments, in conjunction with Mr. Hoyle, in Manchester, on this point. He had a box filled with soil, and tried how much less water came oft' from it than from a rain guage : the difference of course was due to evaporation ; the rain was 33-56 inches; the evaporation was 25-16 inches. The evaporation from water was at the same time forty-four inches. That the evaporation from a surface of water is in these islands so low as the results of Dobson and Dalton indicate, is due to the moisture of the climate ; our atmosphere being already more or less loaded with vapour, and thereby prevent- ing any further increase. This is seen in the great amount of the evaporation from a surface of water in the continental states removed from the ocean. Thus, at IVIanheim, the eva- poration is seventy-three inches, whilst the rain is but twenty- one. Dr. Thomjjson values the average evaporation from the sur- face of Great Britain at thirty-two inches As the evaporation from soil is less (twenty-five by Dalton's result), and from shallow soil or rocky surface still inferior, we cannot be far from the truth in considering the quantity of rain that is not returned to the atmosj)here from the surface, to be one-third of that which falls. Tiie conclusion to wliich Ikiron Dupin ar- rives in discussing, for France, a question similar to that which OF IRELAND. 75 occupies us here, is ultimately the same, although some of the principles from which he calculates cannot, as I conceive, be considered as applicable to this country, as the extent of eva- poration is affected to an important degree by the geographi- cal contour of the surface, by the neighbourhood of the ocean, and by the prevailing winds. We have, in fact, considered the evaporating surface to be as the surface receiving the rain, horizontal and equal. But in nature such does not occur. Take the instance of a valley, bounded by sloping hills, clothed with a scanty verdure. It is evident that during rain the water flows rapidly down the sides of the hills, and collecting in the valley, converts its tran- quil rivulet for a time into a mountain torrent. The water is here removed from the surface of the hills before it has time to evaporate. It is accumulated under an area of probably not one-tenth of that on which it fell, and its tendency to eva- porate is reduced in the same degree. That such condition is not merely the fancy of a theorist, but is considered as real by the best practical authority, is fully shewn in the admirable Report on the proposed reservoirs of the Upper Bann, drawn up by Mr. Fairbairn. After general observations, nearly similar to those I have now made, he says : "in the case of the Deer Meadow Lake, bounded by movmtains M'hose ridge forms a rain guage of 1802 acres, with an average height of 500 feet above the reservoir, of which the area is 215 acres. Here the basin is to the reservoir as 1802 to 215, or 8 to 1 ; and as there can be but little evaporation, except from the reservoir, the loss is very small in proportion with the supply." Under these circum- stances he considers five-sixths of the rain that falls represents fairly the supply running into the reservoirs. We shall here- after see that the quantity of water rendered available by those reservoirs even exceeded Mr. Fairbairn's expectations. Without more circumstance, I shall therefore assume, that out of the thirty-six inches of rain that annually fall in Ire- land, twelve inches finally arrive at the sea, and in its course may become available to industry with a force proportional to the height through which it falls. This height requires also an approximated termination. 76 INDUSTRIAL RESOUKCES The limestone plain which occupies the central districts of the country rises to an elevation of about 300 feet, which is the height of the summit levels of the canals by which it is traversed. The mountainous districts of the north and south raise the average of the island much beyond this number, and we may arrive at a very tolerable approximation to the truth from the following considerations, which are based upon mea- surements conducted by the officers of the Ordnance Survey, and very kindly placed in my hands for the present object, by Captain Larcom, the distinguished officer uuder whose local direction the operations of that important work have been so ably carried on in Ireland. The total area of Ireland being 32,509^ square miles, it is found that there are, Between sea level and 250 ) , „ ^ -> . , , . , c • • • • 13, 242b square mues. feet of vertical height, 3 > « ^ Between 250 and 500 feet of height, . 11,797^ „ 500 and 1000 „ . 5,797J „ 1000 and 2000 „ . 1,5S9| Above 2000 in vertical height, ... 82| ,, Now if we consider the average elevation of these zones to be the arithmetic mean of the extremes, and that the average of the last term be 2500, which, although not, perhaps, abso- lutely true, cannot bo far from the truth, it results that the surface of Ireland is, in average, elevated above the level of the sea, to a height of 387 feet. Calculated on similar principles, the average elevations of the provinces are, Leinster, 378 feet. Ulster, 432 ,, Connaught, 266 ,, Munster, 453 ,, The number for Leinster is very materially influenced by Wicklow, of which the average elevation is 823 feet. With- out Wicklow the average of Leinster is reduced to 327 feet. The distribution of the surface at these various elevations above the sea, is graphically represented in the accompanying OF IRELAND. 77 map, in which the proportionate space occupied by the ground less than 250 feet in height, is left unshaded, whilst the areas between 250 and 500, between 500 and 1000, and between 1000 and 2000 are distinguished by shadings of different and pro- portionate intensities. The areas of more than 2000 feet in height, being but a few points, principally in Wicklow and in Kerry, are not represented, as on a map of such scale, they could not be rendered sufficiently distinct, -without danger of their areas being exaggerated. The relation of the watercourses to the vertical elevation of the surface, is by this map rendered very evident. The height of the districts in which the rivers take their rise, and the di- rection of the lines of greatest elevation which separate the catchment basins of the different rivers, can be estimated by its means. The exact outlines and other characters of the catchment and drainage basins are, however, precisely marked on another map, that on which the extent and localities of the principal bog deposits are shewTi. To this map reference will be again made. A comparison of the map of elevations with the geological map, ■will at once shew how uniformly the limestone occupies the country under 500 feet, and how instantly it is replaced by other rocks, where a greater elevation is obtained. By calculations founded on such principles, we arrive at the conclusion, that the average elevation of the surface of the country being 387 feet, the water which flows in our rivers to the sea, has an average fall of 129 yards, and now finally we may calculate the total water power of Ireland. We had for the total quantity of rain falling in a year 100,712,031,640 cubic yards ; of this one-third flows into the sea, that is 33,237,343,880 cubic yards, or for each day of twenty-four hours, 91,061,216 cubic yards, weighing 68,467,100 tons. This weight falls from 129 yards, and as 884 tons falling twenty- four feet in twenty-four bom's is a horse power, the final result is, that in average we possess, distributed over the surface of Ireland, a water power capable of acting night and day, with- out interruption, from the beginning to the end of the year, and estimated at the force of 3227 horse power per foot of fall, 78 INDUSTRIAL RESOURCES or, for the entire average fall of 387 feet, amounting to 1,248,849 horse power. But mechaaieal power is never thus unintormittingly driven, and if we reduce this force to the year's worli of 300 working days, of twelve hours each, we find it to represent 3,038,865 horse power : that is more than three millions of horse power. Of course much of this enormous quantity of force exists in localities where other circumstances may prevent it becoming useful. The perfect economy of the water for mechanical power may be inconsistent with other equally important ob- jects. Thus the drainage of the districts for agricultural pur- poses, or the maintenance of navigations, may require constant discharge and loss of a certain quantity of water. The various water machines also incur a certain loss of force in working, which may be estimated at a third. But still it may be con- sidered as decisively established that there is derivable from water power, of which I have here noticed only one source, an amount of mechanical force sufiicient for the development of our industry on the greatest scale. The manner in which this force is geographically distributed may be inferred from the position of the principal rivers, the structure of the country through which they flow, and the areas of catchment basins from which, through their tribu- taries, they derive their supply of water. The great central limestone district may be considered as transmitting its waters to the sea, by means of the Shannon, whose total basin is 4544 square miles. Barrow, Nore, and Suir, ,, 3400 ,, ,, And partly also by the Galway waters (Loughs Corrib and Mask), whose basin covers . . . 1374 square miles.

OF IRELAND. 79 The eastern flank of the Wicklow and Wexford mountains is drained principally by the Slaney, from a basin of 815 square miles. Avonmore, ,, 200 ,, ,, Avoca River, ,, 281 ,, ,, The southern counties of Munster supply the waters of the large rivers, which flowing in parallel valleys, east and west, discharge into the ocean on the south-eastern coast. These are : Blaekwater, Waterford, from a basin of 1219 square miles. Lee, Cork, ,, ,, 735 „ „ Bandon River, ,, ,, 228 ,, ,, In the north of Ireland there are three principal outlets for the waters ; by Lough Erne at Ballyshannon ; by the Lower Bann at Coleraine, and by the Foyle at Derry. The areas from which these rivers and their tributaries collect their waters are : Erne, 1585 square miles, Foyle, 1476 „ Bann, LTpper and Lower and the Main, 1266 ,, Blaekwater, Armagh, .... 526 ,, ,, Moreover, the littoral counties pour into the sea a large portion of their drainage waters, by means of a number of rivers of short course, and individually of trifling area of basin; of these may be taken as examples the Lagan at Belfast, drain- ing 227 square miles ; the Roughty at Kenmare, from 475 square miles ; the Main and Inney at Killarney, from 511 square miles ; the Feale and Gale, which unwater the south- western portion of the Munster coal district and discharge into the sea near Listowel, from a basin of 479 square miles. The relation of these areas from whence the rivers derive their supply of water, is rendered evident by inspection of the map, where it will be seen that the districts through which the various rivers flow, are separated from each other by mai'ked lines, which run along the crest of the highest in- 80 INDUSTRIAL RESOURCES tervening ground, so that the rain falling on opposite sides of such line must flow in opposite directions, and the drainage be consequently conducted to a different outlet, by which its waters may escape to the sea. The area thus enclosed and penetrated by a river will form the catchment basin of that river, and the watercourses provided must be of sufficient cai^acity and of sufficiently rapid descent to carry off all the water that may fall within that area, otherwise the district will be exposed to floods, and the surface being kept wet and cold, the soil may become marshy and unfit for profitable agriculture. The area of catchment basin, and the vertical height of fall, are thus the primary elements in relation to water power. The capacities of the various watercourses are also involved in the important questions of drainage and of inland naviga- tion. Now from the consideration that in average thei-e passes to the sea from the surface twelve inches of water, which from the entire area of Ireland, 32,513 square miles, is capable of generating 3227 horse power per foot of fall, it follows that it requires the drainage of just ten square miles to give water for an average horse power per foot of fall ; and on this prin- ciple the force capable of application from the waters of the individual rivers may be estimated. Of course it will be un- derstood, that the force of a tributary, or of the upper por- tions of the river itself, will not be that derivable from the total catchment basin, but from the portion of the basin which actually supplies water to the point where the power is re- quired. For most of the estimates of areas of drainage basins given above, I am indebted to the kindness of Mr. Mulvany, Com- missioner of Drainage. In some, though few, instances, I have obtained values for the water power of certain localities, which may give rather more special interest to the subject, after the general discus- sion that has just closed. The Shannon, that great river, which, penetrating the in- OF IRELAND. 81 terioi- of Ireland, navigable from the ocean to its source, rising in one coal formation, emptying itself through another, and washing the banks of our most fertile counties, delivers into the sea the rain collected from an area, which, according to Mr. Mulvany's estimate, embraces 3613 square miles of coim- try, north of Killaloe. This noble river, which at Lough Allen, near its source, is but 146 feet above the level of the sea, passes slowly along, falling but fifty feet in 150 miles, until it arrives at Killaloe, where its waters rush down the great rapids towards Limerick, and in a space of fifteen miles pre- sent a difference of level of ninety-seven feet, of which the available power may be estimated, at least with tolerable ap- proximation, from the returns and reports published by the Commissioners for the improvement of its navigation. In the geographical character of the basin of the Shannon, we find all the conditions for great evaporation fulfilled. The country, whose waters it receives, is flat, its streams sluggish, the soil upon its banks either deep and retentive clays, or ex- tensive bog. Expanding into numerous lakes of considerable size, often overflowing the lowlands on its banks, it may be considered as almost in the condition of presenting a true water evaporating surface. Still the quantity of water it carries to the sea is of extraordinary power. It has been observed that in wet weather, the level of the water in Lough Derg often rises two or three inches in twenty-four hours ; and has been known to rise twelve inches. As the area of the Lough is 30,000 statute acres, this extent of water weighs 3,000,000 tons for each inch, and hence, so much as 36,000,000 of tons have accumulated in a single day and night. The average diiference between summer and winter level of the Shannon at Killaloe, where narrowing from Lough Derg, it reassumes the river form, is about six feet, but the total of the rises of the water during the year are found, from a dis- cussion of the observations of three years, to be eleven feet. The rising of the waters occupied in average seventy-seven days : in falling to the summer level they occupied 107 days. The quantity of water thus accumulated in the great natural reser- voir of the Lough was 532,534,096 cubic yards, or 403,416,600 G 82 INDUSTRIAL RESOURCES tons, which is discharged in 107 days at the rate of 155,92f$ tons per hour. By this, a force continuous day and night of 177 horse power per foot of fall may be produced. An equal force is of course available whilst the river is rising, and thus through 184 days, or six months of the year, this enormous power is in action, independent of the ordinary discharge which goes on when the waters are at the lowest. When the river is high, the motive force available is far greater than that just now mentioned. An example furnished to me by Mr. Mulvany will shew this sufficiently. " On the 2nd of December, 1836, when the water was 13 feet on the upper sill of Killaloe lock, the observed discharge was 882,450 cubic feet per minute, and on the 10th of that month, the height was 14 ft. 1 in., on the 18th 14 ft. 4 in., at which height it continued until the 25th, with of course a yreutly increased discharge ; on the latter day it began to descend gradually. During the period mentioned, the whole lake rose four inches between the 3rd and 4th, and five inches in two days, between the 5th and 7th, and two inches in other days. These grand rises, at that height of water, extended over the flooded lands as well as the lake, that is, over a surface of from 36,000 to 38,000 statute acres." Now the discharge for the month of December, 1836, may certainly, from the description above given, be taken at one million cubic feet per minute, that is, one and two-third million of tons of water per hour, capable of producing 1885 horse power per foot of fall. The minimum discharge of the Shannon at Killaloe has been estimated by Mr. Mulvany, in the dryest summer, so low as 100,000 cubic feet of water per minute. This is equal to a force of 188 horse power per foot of fall. At this minimiun, however, the flow is kept but for a very short time, certainly not more than a month in the year, which is also the duration that may be allotted to the maximum elevation of the waters. Although it is not possible to deduce from these returns the actual average force exerted by the waters of this river, yet I consider from all the facts I have been able to collect, regard- ing its discharge at various seasons, that the mean cannot fall below .S50 horse power per foot of fall. For as tlie summer OF IRELAND. 83 level of the river, for which the minimum discharge is taken, does not last more than two months, and that during the six months of the rising and the falling of the waters, the force is at least 188 + 177 horse power per foot of fall, and finally, that the maximum delivery at winter level, lasts at least a month, there are nine months of which the force per foot of fall are 2 months at 188, 376 6 months at 365, 2190 1 month at 1885, 1885 Which give an average of 495 horse power. The other three mouths are certainly not below the six months of rising and falling, but in order that the final results may not be pos- sibly liable to any suspicion of exaggeration, I shall take the average force of water available per foot of fall, at 350 horse power, which gives for the ninety-seven feet of fall between Killaloe and Limerick, a total of 33,950 horse power in con- tinuous action, day and night, throughout the year. This, however, is by no means the whole power of the river, for although in the upper portion of its course it flows through a district unusually level, there is yet between Lough Derg and Lough Allen a total available fall of forty-six feet six inches. We may consider, that at the several points on the river, the supply of water will bear the same proportion to that at Killaloe, as exists between the respective areas of their catchment basins, and this is shewn to be a very legitimate assumption, since at Carrick, where the area of basin is about 350 square miles, the minimum quantity of water passing in summer through the bridge has been determined by Mr. Mul- vany to be 10,000 cubic feet per minute. This is just a tenth of the minimum at Killaloe, the basin at which is ten times the area of the surface drained at Carrick. The distribution of the falls on the upper and middle Shan- non will be, when the improvements now in progress are com- pleted, as follows. The area of catchment basin of the river, at each fall, and the average resuitiug horse power continuous, is given in the accompanying column of the table. r. -2 84 INDUSTRIAL RESOURCES AREA HEIGHT TOTAL OF BASIN.

The vast inequality of force at different seasons is the most remarkable disadvantage of water power. It can be perfectly and economically compensated for, as shall be seen hereafter. To judge of the evaporation which goes on in the basin of the Shannon, we must compare those practical results with what theory indicates. The area of the basin of the Shannon above Killaloe is 3613 square miles, and as thirty-six inches of rain give 0-3 continuous horse power per foot of fall for every square mile of basin, the total power of the Shannon, without evaporation, should be 1084 horse power per foot of fall. Its average is found to be about 350, and hence the Shannon transmits annually to the sea 11*6 inches of water collected from its extensive basin, a result re- markably in accordance with that of twelve inches (one-third of the rain) which I have taken as the average of Ireland. If we pass moi'e to the south we shall find a river in which different circumstances prevail. The Lee, rising amidst the picturesque solitudes of West Muskerry, passes by a direct and rapid course through mountainous country to Cork, where it joins the sea. I have calculated the area of country, above Cork, drained by the Lee at 562 square miles. The average rain should, therefore, produce 169 horse power per foot of fall. Some measurements were made at my request by a most intel- ligent friend, at a period when the river was very low, and ad- mitted of greater accuracy than at other times. lie found that there passed through the river in twenty-four hours, 442,800 OF IRELAND. 85 tons of water. This is at the rate of twenty-one horse power per foot. The water passing to the sea was, therefore, just one-eighth of the rain. This is in summer. The average delivery of tlie River Lee is certainly more than treble this. The power calculated from the average for Ireland of one-third of the rain, should be fifty-six horse power per foot of fall. But the rain in the west of Cork is above the average ; the course of the river is direct, and the slope of its basin precipitous. A river in the north of Ireland, concerning the practical efficiency of which we possess numerical data, is the Upper Bann; it rises in Down in the mountains of Mourne, and falls into Lough Neagh, near Lisburn. This river is the most fully economized in Ireland ; its banks present a picture of industry, of comfort, and intelligence, which I am glad to hold up as a pattern to other districts. The natural supply of the river was not enough for the demands of its industrious occupiers ; and Mr. Fairbairn, employed to examine how its capabilities could be increased, made a Report to which I have already had occasion to refer. I have calculated the total available catchment basin of the Upper Bann to be 256 square miles. Hence, without evaporation, and with the rain at thirty-six inches, which coincides very closely with the fact, in that locality, the horse power per foot of fall is seventy- seven. Now Mr. Fairbairn had estimated the force obtainable, when the water was fully brought into play, at eight working horse power. It has resulted, from even the partial execution of his plan, that the river is capable of increase, even beyond that, and ten working horse power per foot is what appears may be calculated on. Now this ten working horse power cor- responds to fifteen horse power on the theoretical standard I have assumed, which supposes there is no loss offeree, and hence the water practically available is exactly one-fifth of the rain. Such are the few facts regarding the actual water power of certain localities which I have been able to collect. It shews how much remains to be done in this department of practical science. If it in any way indicates the route ; if among my i-eaders some may be induced by these explanations to occupy themselves, whilst in the provinces, in those operations, really 86 INDUSTRIAL RESOURCES simple, only requiring care, by which the sectional area and the velocity of the current in a river are determined, the coun- try will be positively benefited ; for such determinations are at the basis of all investment of capital for industrial objects, and the want of them has often occasioned considerable loss of time and money. Before quitting this subject I may mention, that Mr. Bald has published some estimates of the water power of certain lo- calities. He considers that eighteen inches of rain pass to the sea. This is certainly above the truth. Consequently all his numbers are too high. Mr. Henessy, who has recently published an estimate of the total water power of Ireland, supposes, that four-fifths of the rain become available for industry. This proportion, although it may exist in certain mountainous districts, where the water collects rapidly in basins of small area, and passes with a short course to the sea, is certainly too large for an average esti- mate, and he has not attempted to support his views upon any definite numerical results. But Mr. Bald's measurement of the areas of the basins, and of the heights of fall of localities of water power in the west of Ireland, are very valuable, and I have from them calculated the available horse power of the Con- naught lakes, which, together with the area of catchment basin, and the mean height of fall, is given in the following table: LAKES.

We cannot, however, part from the subject without describing, though briefly, its prac- tical application. It is not my purpose to discuss the me- chanical details of water engines. This is done by special mechanical writers. Some engines are fitted for some uses and OF IRELAND. 87 for some localities, others for different conditions ; and it is essential to the connexion of our subject that a certain analysis of the economic efficiency of each should be given here. We may reduce the water engines to four classes. In the first the water acts by its weight ; of this kind is the overshot water-wheel. In the second the action is by impulse, as in the undershot wheel. In the third it is by pressure, as in the water pressure machine. In the fourth, it is by reactive pressure, as in Barker's mill ; and similarly reactive impulse gives origin to the horizontal wheel or turbine. The overshot water-wheel is the most important engine of water power. It is applicable under a great variety of cir- cumstances, and from its inertia it serves as a regulator as well as a producer of the velocity of machinery placed in con- nexion with it. Its construction requires considerable mecha- nical skill that its powers maybe brought fully into play; the form of the buckets; the quantity of water let into each bucket ; the point of the circumference at which the water is to be let on ; the exact centreing of it, so that its motion may be absolutely uniform ; all these are points to be carefully ex- ecuted, as the injurious results of a fault in the prime mover might be very serious. When an overshot water-wheel is well made, and well proportioned to the supply of water, we may consider that there is absorbed by the machine one-fourth of the power of the water, and that three-fourths are delivered capable of producing useful effect. In some wheels 80 per cent, of useful effect is obtained, but this seldom occurs. Wherever the supply of water is moderately large, and that the height of available fall lies between fifteen and fifty feet, the overshot wheel is certainly the engine to be adopted under ordinary circumstances. It is not liable to injury; it is easily repaired; and its prime cost, in relation to its power, is not considerable. In order to derive from it all its power, it must be recollected, however, that the water should act only by its weight ; the principle on which its maximum action depends being, that the water should enter the wheel without impulse, and should leave it without velocity. To fulfil this condition, as far as possible, should be the object of the engineer. 88 INDUSTRIAL RESOURCES In level countries, where, though the (juantity of water may be large, the height of fall may be but a few feet, the under- shot wheel is often employed. The water acquiring a velocity from rushing down an inclined race, strikes the float-boards near the bottom of the wheel, and communicates to the ma- chinery a portion of its own motion. The float-boards are generally set radial ; but sometimes they make an angle of 20° with the radius. In the latter case the water acts slightly by its weight ; but there does not appear to be much difference in the practical results. Now this undershot wheel must be un- derstood to be an imperfect machine. In the overshot wheel the theoretic value of the water is equal to its weight multiplied by its height of fall, and of this force three-fourths are actually available in practice. In the undershot, on the other hand, the theoretic power is but half the weight of the water multi- plied by its height of fall, and of this but two-thirds are avail- able in practice. Hence, the final performance of the undershot wheel is but one-third of the total theoretic power of the water expended. This machine should, therefore, never be used where any other is practicable : it is the least economic. Still in the level districts of Ireland numerous positions occur, where a large quantity of water falls through a height of from two to six feet. Here one-third of the power may be economized by an undershot wheel, and may suffice for all the industrial wants of that particular locality. Beyond six feet, however, I con- sider this machine not to be recommended. From six feet to fifteen feet of fall, the interval between the effective limiting height of water for the undershot and overshot wheels, a form of wheel intermediate to those, indeed compounded, as it were, of them, is most advantageously employed; this is the breast wheel. The breast wheel has float boards like the undershot, but instead of moving in an open race, it revolves in a carefully constructed channel, the sides of which are so closely fitted to its frame, as with the float boards to form in some degree a set of buckets. The water is let on somewhat below the axis, and entering the channel with some velocity, it acts at once by weight and impul.se. The power of the breast wheel OF IRELAND. 89 is intermediate to those of the wheels ah'eady noticed. It is in fact compounded of the two, and in the words of Barlow : ♦* The effect of the breast wheel is equal to that of an iinder- shot whose head is equal to the difference of level between the surface of the reservoir and the point at which it strikes the wheels, added to that of an overshot whose height is equal to the diiference of level between the point where it strikes the wheels and the level of the tail water." Now this gives for the breast wheel a theoretic power of 83 per cent, of the whole ef- fect of the water. In practice about a third of this is absorbed by the machine, and hence the available working effect of the breast wheel may be taken at 55 per cent., rather more than half of the calculated force of the water. M. Poncelet has proposed to form the breast wheel still more on the model of the overshot, by giving to the float boards a curved form, that they may act more effectually as buckets. He considers also that the principle of the overshot should be used in letting on the water, that is, that it should enter with- out impulse and leave without velocity. A model wheel con- structed on his plan gave a useful effect of 74 per cent, of the total power, and working wheels, of which many of large size have been erected in France, are found to economize from 70 to 60 per cent., below which none have fallen. They may be considered as giving in average two-thirds of the total power of the water, and are hence better than the breast wheels of ordinary construction. In conclusion I add, in a tabular form, the proportional available power by each kind of wheel and the heights of fall within which its use may be recommended. WHEEL.

It is that there is a great practical advantage in large wheels. The motive force acts to more advantage at the extremity of a longer lever. The angular velocity becomes small, which is one of the conditions neces- sary to a maximum economy, and the mass of the wheel acts as a fly wheel, and by its inertia preserves a regularity of movement which is of the highest importance in practice. Hence the wheels should always be as large as the mechanical circum- stances of their locality admit, and thus the practical limits above assigned are fixed. It will be seen from the numbers now given, that the average performance of breast and overshot water wheels, taken to- gether, is close to two-thirds of the calculated power of the water they expend. On this is founded a practical estimate of the power of mill streams, frequently employed by engineers, and which it is useful to know. It is that twelve cubic feet of water falling one foot per second is a horse power available. Now this is 720 cubic feet per minute, and as the cubic foot of water weighs 62-5tb, the weight is 45,0001b falling a foot per minute. This is four-thirds of the theoretic horse power, as I have stated at page 42, and thus one-third additional power is assumed as expended in transference to the machines. The water-pressure engine is a machine but little known in this country. In fact, borrowing as we do our mechanical ideas from England, a country, generally speaking, so rich in fuel as to render the economy of water power imimportant, water engines do not fix the attention of mechanists as they deserve. In mechanism the water-pressure engine is essentially the same as a steam engine, usually single acting. The valves and pas- sages are large, as water cannot be wire-dra\^^l like steam. A main-pipe from a reservoir at a distance brings the water to the valve box, through which it enters the cylinder, which, rais- ing the piston, it gradually fills : the entrance valve closes, the water is let off by the opening of an exit valve, and the piston falls by the weight of the macliinery with which it is in con- nexion. Some engines are madf (luubio-acting, in which case OF IRELAND. 91 they are absolutely constructed as the simple high pressure steam engine, but they use cold water in place of steam. Now as to the mechanical power of these engines. The water acts, not by its weight or impulse, but by its pressure. The height of head to give this pressure must, therefore, be con- siderable, but the quantity of water consumed may be very small. In a mountainous district, a reservoir is formed among the hills. From it the water is conducted, not by a costly em- bankment, but by a pipe of a few inches diameter. The ma- chine is erected at the most convenient locality. For every thirty-five feet of head, the pressure is one atmosphere on the piston ; fifteen pounds to the square inch. A head of 350 feet gives, therefore, ten atmospheres, and in mining districts, where such elevation is often available, those engines are pe- culiarly suitable. AYith such a head and a piston of a square foot of surface, moving with a mean velocity of two feet per second, there should be produced a force of seventy-eight horse power, and as the engine is foimd to deliver in practice 70 per cent, of the theoretical amount, the working efficiency of such an engine should be fifty-four horse power. The expen- diture of water would be 120 cubic feet per minute. The expenditure of the same water, acting by the same head, on an overshot wheel, would give seventy-three theoretic horse power, and in practice fifty-five horse power. The efficiency of the water pressure engine is, therefore, a little less than that of the overshot wheel, but it is to be remarked, that a head of 350 feet could not be made use of with any wheel. A wheel cannot be practically used over fifty feet, and hence 300 feet of fall should go to waste, five-sixths of the entire power, all of which is economized with the water-pressure engine. On the Continent the employment of water-pressure engines is very general. At Freyberg, one of the deepest silver mines, the Altemord Grube, is drained by an engine working with two single acting cylinders, which is fixed itself 360 feet below the surface. Its effective duty is seventy per cent, of the cal- culated power. In Bavaria, where the water-pressure engine has received its most remarkable improvements, from the hands 92 INDL'STRTAL RESOURCES of Reichenbach, the brine, from the saltmines of the neighbour- hood of Salzburg, is ti'ansmitted over the mountains, 1200 foot high, for a distance of seven miles, by means of a series of nine engines, that the evaporation may be carried on in a district where fuel is cheap. The effective duty of these engines is from 60 to 72 per cent, of the theoretical force. In France in various localities they are erected. One at Huelgoat in Finis- terre, which works with a column of water, sixty-five yards high, and draws up the waters from the lead mines from a depth of 305 yards, delivers 64 per cent, of the theoretical force, and when it is placed in connexion with the deeper pits, for which it was constructed, is expected to increase its efficiency to at least 70 per cent, of theory. These machines are now also being introduced into Corn- wall. Mr. Fairbairn and Mr. Darlington have erected water- pressure engines in the mines of that country. One erected by the latter engineer has two cylinders of fifty inches diame- ter and ten feet stroke. It is worked by a column of water thirty inches diameter and forty-four yards high. It works four to six strokes in the minute. The blow produced by the valve is almost totally gotten rid of by jieculiar mechanical arrangements invented by Mr. Darlington, but which need not be desci'ibed here. The power of this machine, calculated by the principles given above, from its dimensions and the supply of water, should be 166 horse power, which at 70 per cent, becomes 116 horse power of practical efficiency. I must remark, however, two disadvantages of this machine : 1st. The water flowing with a constant pressure into the cy- linder, imparts to the piston an accelerated motion, so that finally the stroke is terminated by a shock from the inelastic water, whilst in the steam engine, the steam acts as an elastic cushion, by which the piston is brought to rest, and injury to the machinery prevented. To remedy this, in the water en- gine, many plans are devised; an air vessel on the cylinder; springs under the working beam ; a cavity containing air in the piston. By means of such provisions this disadvant.agc is removed, and although the motion is not regular enough for certain delicate uses, yet for draining mines, and numerous OF IRELAND. 93 other purposes, it is most effectual. The second disadvantage is, that its parts, being like those of the steam engine, are somewhat complicated, and require more repair and atten- tion than those of water wheels. But in this it is not more troublesome than the steam engine, which nobody faults on that account. The machine which is popularly known as Barker's mill, and in which water issuing from an orifice gives motion to machi- nery by its reactive force, is not one with which I need occupy attention. Its theory indicates the maximum effect to be but one-half the true power of the water, and as in practice further deduction must be made, it is likely that not one-third is really economized. It is hence one of the worst water engines, and I only name it here because a modification of it by Messrs. Whitelaw and Skerrit of Glasgow has lately been brought for- ward, said to economize power in as great a degree as the overshot wheel. In the new form the horizontal arms are curved in such a manner, that the water, when passing from the centre, moves in a straight line, the arms by their curva- ture reti'eating as it advances. In this way the centrifugal force of the water, which, in the old straight arms, partly acted against the reactive force, is obviated ; indeed as it is exerted along the axis of the tube, it is added to the power generated by the reaction. The results of the use of this en- gine published by the patentees are highly favourable to it, but I understand, that in many instances it has not fulfilled expectation. Without intending, therefore, at all to dispa- rage this improved form of the reaction mill, I may observe that more extended practical knowledge of its power is re- quired before we can rank it with those useful machines already noticed. Finally, I have to describe a water engine of quite modern invention and of remarkable efficiency, the turbine, invented by M. Fourneyron. Coals being abundant, the steam engine is invented in England ; coals being scarce, the water-jiressure engine and the turbine are invented in France. It is thus the physical condition of each country directs its mechanical genius. The turbine is a horizontal wheel furnished with 94 INDUSTRIAL RESOURCES curved float boards, on which the water presses from a cylin- der which is suspended over the wheel, and the base of which is divided by curved partitions, that the water may be directed in issuing, so as to produce upon the curved float boards of the wheel its greatest efl'ect. The best curvature to be given to the fixed partitions and to the float boards is a delicate prob- lem, but practically it has been completely solved. The con- struction of the machine is simple ; its parts not liable to go out of order, and as the action of the water is by pressure, the force is under the most favourable circumstances for being utilized. The efl^ective economy of the turbine appears to equal that of the overshot wheel. But this economy in the turbine is ac- companied by some conditions which render it peculiarly va- luable. In a water wheel you cannot have great economy of power without very slow motion, and hence where high ve- locity is required at the working point, a train of mechanism is necessary, which causes a material loss of force. Now in the turbine, the greatest economy is accompanied by rapid motion, and hence the connected machinery may be rendered much less complex. In the turbine also a change in the height of the head of water alters only the power of the machine in that proportion, but the whole quantity of water is economized to the same degree. Thus if a turbine be working with a force often horses, and that its supply of water be suddenly doubled, it becomes of twenty horse power ; if the supply be reduced to one-half, it still works five horse power ; whilst such sudden and extreme changes would altogether disarrange water wheels, which can only be constructed for the minimum and allow the overplus to go to waste. Mr. Riihlman, who has published a very full Report on the theory of this machine, and on the practical performance of the more important of those erected on the Continent, con- cludes, that it is certainly wrong to suppose that turbines can altogether do away with the use of vertical wheels, and that the economy of 80 per cent, of the theoretical effect, obtained by Fournoyron with some wheels, cannot be expected in all cases ; but tliat certainly in practice from GO to 70 per cent. OF IRELAND. 95 may be depended on. As to the choice between turbines and vertical wheels, his decision is, that where there is a fall of a certain height, which may be economized by means of an over- shot wheel, such is to be preferred to the turbine, for when carefully arranged, the overshot wheel economizes more than 70 per cent, of the theoretical power ; the only exception to this may be in those cases, where, as in corn mills, the horizon- tal motion of the turbine may be directly utilized, or where the engine must work against considerable backwater, in which case the effect of the turbine is but very little affected, though the ordinary wheel loses considerably in power. But in all cases of very high or very low falls, Mr. Riihl- man, as well as all other engineers who have written on the subject, gives decided preference to the turbine, and considers, that their universal application to such circumstances can only be retarded by want of foresight and of knowledge of their actual performance. The extreme conditions under which the turbine will act, are shewn very satisfactorily by the result of one erected at St. Blasien, and by which is driven the machinery of a cotton mill, containing 8000 sj^iudles, with carding machines, beaters, and all other necessary engines. The flow of water was one cubic foot per second, but a height of 332 feet was available. On a fifty foot overshot wheel, this quantity of water would give but five and three-fourths theoretical, and but four and one-fourth practical horse power ; but the water, being col- lected at a distance of two miles, is brought to St. Blasien by a metal pipe eighteen inches diameter, and delivered to the tiu-bine with all its pressure available. The wheel of the tur- bine is but one foot diameter, and it makes about 2250 revo- lutions in a minute. Its theoretical force is thirty-eight horse power, of which nearly three-fourths or twenty-eight horse power is delivered in practice. Contrasted with this machine, are the great turbines erected at St. Maur, near Paris, to grind corn. The wheel of each turbine is six feet in diameter ; its paddles ten inches high. The head of water averages 11 ft. 9 in., and the discharge is thirty-four cubic feet per second. Each turbine drives ten pair 96 INDUSTRIAL RESOURCES of millstones, with all accompanying cleansing machinery, and in twenty-four hours grinds fifteen tons of corn. The theore- tical power of each turbine equals forty-five and a half horse power ; the practical efficiency is thirty-three. In another case where the height of the fall of water to a turbine was but thirteen inches, the economy in practice was 55 per cent, of the theoretical power. Having thus considered the machines by M'hich water power is rendered available to industry, it remains to examine some circumstances affecting it, which are not of inferior impor- tance. The worst feature of water power is, that its production does not depend upon the will of the person who employs it. Originating in cosmical laws, which, from their complexity, have as yet totally defied the predicting power of science, the amount of water flowing along any given river cannot be es- timated for any time in advance, and hence the manufacturer has open to him one or other of but two courses, each of which is beset with disadvantages, which I shall endeavour to enu- merate. In the first place, having estimated the smallest quantity of water that is available in summer, he may propor- tion his machinery, and work to that amount of power. But by doing so, he sees pass by him through the greater portion of the year, power many times as great as that which he eco- nomizes. The forces of nature flow by his door, but he knows not how to control them. The powers which could execute in a day that which occupies his factory for a week, are running to waste, but the intelligence which might arrest them in their course, and make them pay tribute, is not possessed by the manufacturer whose case we have taken, and hence he drags along an existence dull and unprofitable, until some turn of commercial circumstances seals his ruin. The alternative course by which the machinery is constructed of power suf- ficient for the employment of the average quantity of water, is accompanied by not less evils. In fact, in the dry season, in- dustry is arrested ; there is not water enough to work the mill : workmen unemployed, their families possibly without food, a prey to discontent, are conscciuencos sufficiently se- OF IRELAND. 97 rious ; whilst orders remaining unexecuted, contracts unful- filled, may entail loss of the most serious kind upon those whose capital is invested in such works. In addition we must consi- der, that upon a river, factories, by which its water is econo- mized, present great obstacles to the flowing of the current, and hence in case of sudden floods, by the arresting of the stream at the mill works, the lands higher up are rendered liable to inundations, which may be destructive to property and even life. Thus the employment of water power is liable to interruption, and may be productive of injury, affecting not merely the interests of the workmen and the capitalists who share in its advantages, but also of those at a distance who derive no benefit from its use. I believe that the disadvantages to which water power is liable, are fully expressed in the above statement. Now I do not hesitate to say, that they are all capable of being removed. If we give to the conditions of water power the same care that is bestowed upon the circumstances of steam power, those dis- advantages disappear, and we obtain from water, dm-ing the year, a steadiness of supply, and a regularity in work, that leave nothing to be desired. In fact, as we have under the earth vast deposits of coal, the source of steam power, from which we draw, at desire, the necessary supply, so is it necessary to organize on the surface vast depositories of water power to be made available at our will. In place of wretched mill ponds, by which a stock of water is scarcely secured for a week, there should be a basin so capacious, that the floods of an entire winter might be re- ceived, and thus invested for most profitable expenditure in summer. This is the course actually pursued where industry is most active and enlightened. I shall proceed to detail the circumstances of one or two such cases, in order that they may serve as examples of what may be done. The quantity of mechanical force that is brought suddenly into existence by the waters of a winter flood, and which, for want of sufficient reservoirs, is altogether lost in almost every case, may be exemplified by considering the quantity of water, which, during a few days of the winter of 1840, accumulated in H 98 INDUSTRIAL HESOUHCES Lough Derg. Tho depth of water on the upper sill of Killaloe lock on tho respective dates were : November 13th, 9 feet 8^ inches. 16th, 9 „ 9 17th, 10 „ 9 18th, 11 ,, 1 Stationary until, December 8th, 10 „ 9 „ 9th 11 „ 10th, 11 ,, 6 11th 11 „ 11 In the twenty-four hours of the 16th and 17th November, the water rose twelve inches, and in the three days and nights of December 8th to the 11th, it rose fourteen inches. Now each inch of water on this lake amounts to 8,000,000 of tons in weight. These floods, therefore, l)rought down, first in one day, 36,000,000, and then in three days, 42,000,000 of tons of water, over and above the vast discharge constantly going on at the orifice of the lake. Now if these masses of water could have been, by suitable engineering arrangements, preserved from immediate and useless expenditure ; if their discharge could have been spread over the entire year, these two quan- tities alone, of twelve and fourteen inches of rise of surface, the fruits of four days and nights of winter flood, would be able to generate, on the fall of the river below Killaloe, a force acting throughout the entire year, night and day, of 967 horse power. The mill owners On the Upper Band were exposed to all the disadvantages above stated. Floods drowning their mills in winter ; drought stopping their works in summer. Mr. Fair- bairn was employed to survey the district, and proposed the formation of three reservoirs, the circumstances of which I shall briefly describe in his own words. " Lough Island Heavy, which is the best situated reservoir, is a natural lake bounded north and south by land of conside- rable elevation. It has good feeders, which, with the overplus waters of the River Muddock, would give ample supplies, and fill tho reservoir once or twice in the year. The present area OF IRELAND. 99 of the Lough Is nhiety-two and a half statute acrea. On this is to be raised thii'ty-five feet of water, and drawn to a depth of forty feet under that height. The area thus enlarged will be 253 acres, equal to 140 acres thirty-five feet deep and 1 13 acres fifteen feet deep, making a total of 287, 278, 200 cubic feet of water. " The Deer's Meadow, embanked to 100 feet above the level of the river, will flood 215 acres to twenty-four feet average depth, having 224,769,600 cubic feet of water. The feeders are uncertain, being but the drainage of 1802 acres. This reservoir should, therefore, be the last executed. " Corbet Lough is a valuable auxiliary to the other two. It has excellent feeders, and controls every mill from its outlet to Lough Neagh. It may be raised eighteen feet above its summer level. It should then cover seventy-four and a half acres, and contain 46,783,440 cubic feet of water. The supply is from the flood waters of the Bann by a canal cut and land feeders. ' ' The sum of the three reservoirs : CUBIC FEET. ACRES.

Now as there are 350 feet fall, this is a total on the Bann, of 1750 horse power, and, adding the water of the river com'se, the power may be considered as eqiuvalent to 2800 horse power." The above is extracted from Mr. Fairbairn's Report ; he pro- ceeds to some estimates of the cost of these reservoirs. The total expenditure he values at £32,000, and deduces, that the annual cost of delivery of water should be £1860, arranged as h2 100 INDUSTRIAL RESOURCES below, and that oach reservoir gives for a shilling expense, the following number of tons of water : TOTAL EXPENSE.

Such was Mr. Fairbairn's plan ; I was aware that it had not been all carried into execution, but that such parts of it as were cai-ried out had produced even greater effects than he had estimated. Through the kindness of Mr. Bergin I was enabled to communicate with Mr. Bateman, who was Mr. Fairbairn's colleague in the execution of the works, and received from him, in answer to certain queries, replies which I subjoin. "Of the works authorized by Act of Parliament, the Lough Island Reavy Reservoir has been completed, and been in ope- ration for upwards of three years. " The land for Corbet Lough Reservoir is purchased, and the Deer's Meadow Reservoir abandoned. " Previous to the construction of the Lough Island Reavy Reservoir, the River Bann, where most closely occupied by mills and bleach works, had not water power mon; than equal to one or one and one-half horse power upon each foot of fall, during the dry periods of the year, for months together. *' The lowest power now is about five horse power to a foot of fall, being a gain, by means of the reservoir, of about three and one-half horse power per foot, and the regular full quan- tity is uniformly maintained. " Should tiie Corbet Lough Reservoir ever be completed, the minimum power of the river, below its outlet, will be brought up to about ten horse power per foot of fall. " In dry seasons, when the river has fallen to its lowest vo- lume, the discharge may probably be equal to from seventy to one hundred cubic feet per second. In floods it amounts to 3 or 4000 cubic feet per second. OF IRELAND. 101 "Below the Lough Island Reavy Reservoir there is a fall of 124 feet upon the River Muddock, partially occupied by small corn and flax mills. " On the River Bann, from its junction with the Muddock to the Corbet Lough Reservoir, there is a fall of forty-four feet and a half, at present occupied by limited establishments, which are capable of great improvement. The regular power now is never less than about five horse power per foot of fall. " Below Corbet Lough to the last mill on the river there is a fall of 168 feet ; on this portion the more extensive establish- ments are situated, — the whole fall being occupied. The river is now equal to about five horse power per foot of fall, and by an outlay of between 2 and £3000 on Corbet Lough may be increased to ten horse power per foot. "The mills have been gradually increasing since the im- provement of the river, but few are yet enlarged to the extent they may be. " The annual rate levied upon the river for the cost of the improvement is £10 per foot of fall, which will diminish as the works increase in value, and the river is more extensively occupied. As the measure of a river, when no other assistant power can be applied, must be taken at its minimum, the gain already acquired is about three and one-half horse power per foot, which, at the present rate, is equal to a cost per horse power per annimi of imder £3. The cost of the same power by steam in that district would be from £20 to £30 per an- num. " Should the full scheme be developed by the completion of the Corbet Lough Reservoir, the cost of the additional power will be little more than 20s. per horse power per annum. "J. F. Bateman." We here see how fully the so called natural disadvantages of water power are obviated. I shall in addition notice an in- stance taken from Scotland, where the result has been, not merely the inci'ease in amount and steadiness of power pre- viously existing, but absolutely the creation of a vast water power, where none had been deemed to exist before. The inhabitants of Greenock had long suffered from a want 102 INDUSTRIAL RESOURCES of water for domestic use. Several engineers had reported, that the circumstances of the locality did not allow of any co- pious supply of this necessary element of cleanliness and health ; but at last Mr. Thorn, having examined the surrounding coun- try, astonished the people of Greenock by asserting, that not merely water sufficient for domestic and municipal purposes might be brought in, but that water power might be made available for mechanical purposes to a very considerable amount. His scheme has been carried into effect. His calcu- lations have been more than borne out, and the rapid rise of Greenock as an emporium of commerce and industry is, in no small degree, due to the bold foresight of the engineer of the Shaw's Water Woi'ks. I shall extract a few notices of these works from an account of them printed some years since, and now extremely rare. "The distinguishing characteristics oi this scheme are the following Instead of erecting works on natural waterfalls, on the banks of rivers, in remote and almost inaccessible places, where immense capital must, in the first instance, be expended in forming roads and houses for the work people, as well as a heavy and perpetual charge for carriage to and from the seat of trade, — the water is carried, by an aqueduct, from the river and reservoirs, to a populous sea-port town, with a redundant unemployed population, where roads, harbours, piers, and every thing requisite for the most extensive trade and manu- facture, are already foi'med. Besides, by thus forming artificial waterfalls on advantageous grounds, every inch of fall, from the river or reservoir to the sea, is rendered available; whereas, by the former mode, only a very small part of the fall could, in general, be employed. In the present case a fall of 312 feet has been made available, of which not more than twenty was formerly occupied, or thought capable of being usefully employed. But, besides the immense advantage thus gained by increasing the fall, a still greater advantage is obtained from the greatly increased, and perfectly unil'unn, supply of water ; by the adajitation of the various reservoirs, aqueducts, basins, and self-acting sluices — as will be seen by the descrip- tion of the purtb which they respectively perform. OF IRELAND. 103 " The embankmeat of the great reservoir, which Is sixty feet high from the bottom of the rivulet, is now very nearly, and in a few months will be entirely, finished. " This reservoir contains two hundred and eighty-four mil- lions, six hxmdred and seventy-eight thousand, five hundred and fifty ("284,678,550) cubic feet of water ; and covers two hun- dred and ninety-four and three-fourths imperial acres of land. " The compensation reservoir contains fourteen millions, four hundred and sixty-five thousand, eight himdred and ninety-eight (14,465,898) cubic feet of water ; and covers about forty imperial acres. Its embankment is twenty-three feet high from the bottom of the rivulet. " The auxiliary reservoir, No. 3, contains four millions, six hmidred and fifty-two thousand, seven hundred and seventy- five (4,652,775) cubic feet of water : and covers about ten im- perial acres. " The other auxiliary reservoirs, Nos. 1, 2, 4, 5, and 6, are now about to be formed, and will contain something more than six millions cubic feet of water. " Thus, the reservoirs already formed, contain three hun- dred and three millions, seven hundred and ninety-seven thou- sand, two hundi'ed and twenty-three (303,797,223) cubic feet; and when the other five auxiliary reservoirs are finished, the whole will contain above three hundred and ten millions (310,000,000) cubic feet of water." Anxious to obtain information as to the actual condition and performance of these remarkable water works, and unable per- sonally to visit Scotland, I have to thank one of the most emi- nent men that coimtry has presented to the practical sciences, for a note descriptive of the power that is now produced by the water so economized. JVIr. Scott Russell replied to my in- quiries in the following words : " My dear Sib, — I had hoped to have been able to get a full and very satisfactory accoimt of the Shaw's Water drawn up for you by a competent engineer, resident on the spot ; but I find that so many delays are occurring to prevent this, that I now write to beg you will not calculate upon it : had my own time permitted I should have done so myself, but now, just when I might have hoped for leisure, I am taken from home. 104 INDUSTRIAL RESOURCES " I have, however, procured a copy of a now scarce pamph- let, printed some thirteen or fourteen years ago, before the works were finished, giving some accoimt of them as proposed. 1 may now add for your information, that every thing y)/-e weight. 150,000 500 feet fall. 50,000)75,000,000(1500.

" Thus then a power has been created and brought six miles and a half to the suburbs of populous towns, equal to the power of thirty steam engines of fifty horse power ; being equivalent to the creation of wealth or productive capital to the extent of £75,000 ; and the annual effect of which, when fully employed, will be something like the employment of 7000 people, and the annual distribution of something like £300,000 per annum in wages in a single town ; besides the supply of ample store of water for the use of the town. " Such, my dear Sir, is a hurried sketch of what has been accomplished : the accompanying pamphlet will tell you some- thing about the details. What further may be necessary for your pm-pose let me know, and I shall try and send it you. "J. Scott Russell." The greater number of Irish rivers are more or less analo- OF IRELAND. 105 goiis to the Shannon, in having lakes either at their origin or on their course, and hence present facilities for the aceiunula- tion of water power of the highest interest to the mechanical engineer. The concentration of the waters of a district in such reservoirs, by appropriate embankments, may be, and in most cases must be connected with another operation of the greatest importance to the agriculture of this country, the drainage of the surface. As an example of how both objects maybe at the same time secured, and how well the physical circumstances of the country lend themselves to their accomplishment, I may notice the relations of Lough Ennell, near MuUingar, to the River Brosna, by which its waters are carried to the Shannon. The facts are taken from Mr. Mulvany's Report. The catchment basin of the Brosna discharges almost alto- gether into the lake, the waters flowing directly to the river course being comparatively trifling. The ditference of winter and smnmer level is but two feet, yet by this a great extent of land is flooded. Mr. Mulvany proposes to deepen the channel of the lake and river by these two feet, by this means reliev- ing the flat lands, and rendering the winter accumulation of the water available for the supply of the mills upon the river during the dry smnmer seasons. The area of Lough Ennell is 3603 acres, and at two feet in depth it should discharge 314,000,000 of cubic feet. As in the case of the Dodder this supply would probably be available tvdce in the year, for the midsummer floods, though not so great as those of winter, will be in all cases sufficient to replenish such reservoirs. Hence as the difference of level of the Brosna issuing from Lough Ennell, and where it joins the Shannon, is 154 feet, a force continuous through half the year of 692 horse power, or four and one-half horse power per foot of fall, should be made available. The River Dodder, although trifling in magnitude, is yet of much interest to us, from the amount of industry which it sus- tains in the immediate neighbourhood of Dublin. There are situated on its banks at present twenty-eight mills occupied ■with various manufactures, as paper, flour, woollens, cloth, &c. This stream, passing by a highly inclined channel from the 106 INDUSTItlAL I1ES0UUCE3 flaiilis of tlic Dublin mountains to the sea, is liable to very great fluctuation in the amount of its discharge. It frequently has done great damage to the lands and edifices along its banks, by sudden floods, and in summer its waters fall so low, that the mills may be considered as being kept idle half time for a period of three months in the year. At present the occupied fall upon the Dodder is 370 feet. The total horse power which is now precariously available, is estimated at 926, which is two and a half horse power per foot of fall. The question of rendering the supply of water more uniform, and of economizing a larger proportion of its force, has been recently taken up by the Board of Works, at the re- quest of the mill owners upon the river, and an accurate survey has been made, and a Report drawn up by Mr. IMallet, whose union of scientific and practical skUl is so well known. Mr. Mallet proposes to form, by means of an embankment about 2000 feet long, and 100 feet high at its centre, across the head of Glenismaul, a reservoir with an area of 162 statute acres, and capable of containing 228,000,000 of cubic feet of water. The catchment basin of this reservoir should have an area of 6070 acres, cliiefly mountain bog, and from the quantity of rain which falls in that hilly district, Air. Mallett calculates, that the reservoir should be filled at least twice in the year, and hence a total annual quantity of water of 456,(X)0,U00 of cubic feet obtained, which Mr. Mallet values as equivalent to 1387 horse power in constant operation. On the construction of this reservoir, it appears by Mr. Mallet's Report, that the total force of the river should become practically equivalent to 2038 horse power. This is five and a half horse power per foot of fall; more than double that now irregularly in operation. The probable cost of these improve- ments may be taken at 86s. per annum per foot of fall, or 23s. per additional horse power. That is, the expense is just one- tenth that of the corresponding steam power, or one-seventh that of the mere coals for a steam engine. As I discussed the question of the cost of power so fully when speaking of the production of steam, it will suffice to no- tice briefly the circumstances of water power as to cost. It is OF IRELAND. 107 only necessary to contrast it with steam power. It is certainly much clieaper, not merely in Ireland, but in all places where it is available. An eminent manufacturer in Leeds said to me, that water power is cheaper than steam at the mouth of the coal pit. All evidence bears this out. In Mr. Fairbairn's Re- port, and Rlr. Bateman's letter, this point is decided, as re- gards the Upper Bann. Even at present it may be taken at £3 per annum per horse power, — steam costing from £20 to £30 ; it may thus be averaged at one-eighth. But ^Ir. Bate- man considers, that when the reservoir system is worked out, the horse power will be had for 20s. per year, not one-twentieth of the cost of steam. Regarding the Shaw's Water Works we also have money es- timates, which are highly valuable, as they place the relative cost of power by water and steam in contrast, not merely for Ireland, where steam is dear, but for the banks of the Clyde, where coal is at its lowest price. Mr. Thorn thus describes the system followed in Glasgow, which is different from any- thing here. With us a builder speculates only in houses, in Glasgow he speculates in cotton mills. " I have stated the cost of steam power at £30 for each horse power. Let us see its mai'ket price in Glasgow : there it is customary to provide a house for the manufacture, with the steam engine, great gearing, and steam pipes, — and keep the engine going twelve hours a day, and heat the work, for £50 for each horse power. " The cost of erecting a mill or factory, capable of contain- ing machinery for the cotton manufactm'e, to the extent of thirty horse power, with the great gearing and steam pipes, but ex- clusive of steam engine and engine-house, may be taken at £4200. Allow the landlord 8 per cent, on this sum, £336, and for heating the house by steam, £84, together £420 ; which is a fair return for every thing except the steam power. But the landlord draws for the whole a rent of £1500; which leaves for the power a rent of £1080: divide this by 30, the number of horse power, and it gives for each £36 annually. " The average water rent for each horse power at Greenock is £3 ; the average rent for two acres of land to be fued along 108 INDUSTRIAL RESOURCES with each mill site if required, is £16. The work being of fifty horse power, take one-fiftieth of this sum {(is. 5d.') for each horse power. Interest on £2000, the cost of a water wheel, arc, trows, &e., for a work of fifty horse power, £100; one- fiftieth of which is £2, making the whole cost of water power, for one horse power, at Greenock, £5 6s. 5d. " Thus each horse power, by water at Greenock, costs upon the whole £5 6s. 5d., being £30 13s. 7d. less than the cost of one horse power by steam at Glasgow. Besides, this calcula- tion includes the rent of two acres of land for each mill at Greenock, whereas at Glasgow no land is taken into the ac- count, except the spot on which the work stands. Were the same quantity of ground given to the mill at Glasgow, at the rate it brings there, it would throw the balance still more in favour of Greenock." Thus, whether we take jNIr. Bateman's value, which is for the bare supply of power ; or Mr. Thom's value, which includes the delivery of the power in a working form, we see that the cost of water power is not more than one-tenth of the cost of steam. Why then is steam so much used ? In the first place, water power is available only in certain localities, where other more influential circumstances may forbid the introduction of manufactures ; and secondly, the influence of the cost of power is generally so small in mechanical industry, that the question of saving in regard to it is swallowed up in more important questions. Still, wherever water power is to be had, it is al- ways employed in preference to steam, as I shall, in fact, shew; but it is first necessary to notice an objection to water power, of a very absurd kind, which, however, requires refutation, because it is held by many persons in Ireland, otherwise well informed, and exercises very considerable influence upon pub- lic opinion as to the manufacturing circumstances of the coun- try. This idea is to the effect, that there is an inherent defect in water power that must prevent its being ever extensively used in industry, to wit, that tlio water soaking into a water wheel at night renders whichever side is then undermost tlie heavier, and this preponderating afterwards, gives an unequal and jogging motion wiilcli unfits the wheel for any delicate work. OF IRELAND. 109 I shall transcribe, in order to preclude further misunder- standing on this point, one passage from the article " Steam Engine," in the Encyclopfedia Britannica. The article is written by Scott Russell. •' Mr. Lucy had constructed at Bii-mingham a flour mill driven by steam ; and it had been his object to obtain perfec- tion without any limitation of expense. He had got one of Bolton and Watt's best steam engines, and yet he found that his mill neither produced such perfect flour, nor moved so smoothly as mills driven by water. On the contrary, it was found that the irregularity of the motion produced a larger quantity of coarse than of fine flour, at a mercantile loss to the owner ; and it was likewise found that the irregular propulsion a tergo intervening with the uniform motion, towards which the millstones tended by their own momentum, produced a clanging reciprocation along the whole line of toothed gearing, which was most injurious, and rapidly destructive to the tooth- ed wheels. When we visited the spot in 1838, the ruins of for- mer wheels, most unequally worn and totally destroyed, were strewed about the yard. The usual plan of increasing the weight of the fly-wheel was resorted to without success ; and Mr. Lucy applied to Mr. Buckle to propose a remedy for the evil. This remedy Mr. Buckle found in the very simple con- trivance of a pneumatic pump. " So perfect was the action of this mechanism, that the fly- wheel had been wholly removed, and the engine and the whole mill-work were moving in the most smooth and effective man- ner. It was found that the change enabled them to give all the grinding stones a greater velocity than formerly, so that the quantity ground was greater, in the proportion of 5Q to 52, and the quantity of the finest or first flour, from the same wheat, was likewise much increased ; so that, both by quantity and quality, the owner of the mill was now able to ' command the market.' The same motion has subsequently been applied to cotton mills with perfect success; the quality and the quan- tity of yarn produced being much improved." Now it may be observed that ]\Ir. Russell does not proceed to explain that water power may be employed, but to describe 110 INDUSTRIAL RESOURCES the endeavours of engineers to rentier the steam engine as re- gular and as useful for delicate work, as the water wheel is found to be. In fact, cotton spun by water power bears, and has always borne, a higher price than cotton spun by steam power. Moreover, if we analyze the power employed in Eng- land in the spinning and weaving factories, we shall have very conclusive evidence on the point. In the estimate of the state of the cotton manufacture in 1833, drawn up by Mr. Baines, and of which the principal items are given in page 64, he con- siders that of the 4-1,000 horse power employed, there are Steam power, 33,000. Water power, 11,000. But we have much more complete and more accurate num- bers given in the Returns of tlie Factory Inspectors for 1839, of which the following is a summary. The total mill power -in factories subject to inspection in England was 83,264 horse power. Of these there were 62,846 horse power, steam ; 20,418 ,, ,, water; coinciding with Mr. Baines' general view of three- fourths steam ; and one-fourth water. In Lancashire, where coals are so cheap, we might suppose that nobody would use water, but we find : Total mill power inspected in Lancashire is 86,446 horse power : Consisting of. Steam, 32,123 horse power. Water, 4,323 ,, Thus, one-ninth of the total mill power of Lancashire is water power. But in order to estimate how far water power is valued, we must learn, not merely how muph is used, but how much is left unused. Now 1 have endeavoured to calculate, on the same principles as I adopted for the surface of Ireland in the b(!ginning of this chapter, the theoretical water power of Lancashire ; I have found that it is represented by 72,600 OF IRELAND. Ill horse power, taken as working continuously. Now the 4323 horso power economized, makes 6 per cent, of the entire ; and as there are in Ireland a million and a quarter of such horse power, it follows that if we economized our water all over Ire- land, in the same degree as water power is actually econo- mized in Lancashire, we should have at work a force of 75,000 horse power, that is to say, almost equal to the mill power of England returned by the Factory Inspectors. This shews how water power is valued in Lancashire. In fact, advantage is taken of every possible situation. The River Irwell, which passes by Bolton and Manchester, and washes the heart of the factory districts, is the hardest worked stream probably in the world. It has, from its first mill at Bacun to Prestolee near Bolton, a fall of 900 feet, of which 800 are ac- tually economized by mills. I do not know another example of such complete application of water power as in that place, where coal is on all sides available. We may, therefore, pass away from this question, of whether water power answers for mechanical purposes, which I should not have at all noticed, but that the public often receive a bold statement from a pub- lic man, without troubling themselves to examine whether it be likely that he understands what he talks about. Contrast with this the actual economy of water power in Ire- land. By the returns of 1839, there are employed in Ireland : Steam, 1503 horse power. Water, 2147 „ „ It has been found that to give to water power its full economy and value, it is necessary to secure its steadiness of supply by the construction of reservoirs, in which such quantity of water may be retained as shall suffice for the average performance of the machine during the entire year. Another mode of compen- sating for the deficient supply of water in dry seasons remains to be described. This consists in having also a steam engine of such power as to be supplemental to the water wheel, and according as water fails, to work the engine, so that the me- chanical force exerted by the steam engine and water machine together, may be constant. This mode is actually adopted in 112 INDUSTRIAL RESOURCES many localities. In the factories of IMessrs. IVIalcolmson at Portlaw in Watcrfoi'd, two engines of a hundred horse power, and two overshot wheels, of nearly equal force, thus work together. There is no mechanical difficulty in the co-adapta- tion of these prime movers. Where circumstances prevent the formation of great reservoirs, which, indeed, must perhaps always require the co-operation of several manufacturers, and, therefore, become practicable only in certain localities, the union of steam power with water power, so as to combine the economy of the one with the convenience of the other, presents probably a result beyond which industry need not go. I have so far described the amount and the application of water power, as it is derived from the residual rain water flowing down the declivity of the country to the sea. This is, in fact, all that is popularly understood by water power ; yet it is far from being the only source of mechanical industry which is derived from water. Another of great interest re- mains to be considered. From the observations hitherto made it appears, that around the coasts of Ireland the tide rises through a height, which may in average be taken at twelve feet. Our tides are de- rived, that is to say, they result from the action of those vast masses of water in the great oceans, which being raised above, or depressed below their proper level by the attractive forces of the sun and moon, force, in regaining their position, into, or di*aw from, the narrow seas and channels, such as ours, quan- tities of water, which thereby form true currents, as much so as the current of a river, and are equally available to produce mechanical effects. Hence the motion of the tide becomes a source of power, and tide mills form an important variety of water mills. In England they are scarcely used, coals being so cheap, but to us, by proper application, I am convinced they may become an important basis of industry. In order that the force available from the tide may be properly understood, it not being much noticed in mechanical books, I shall proceed to describe the principles of its application more in detail, than otherwise I should deem necessary. If we conceive a reservoir situated near the shore, and sc- OF IRELAND. 113 parated from the sea by a narrow canal, and that at low water the reservoir is dry, we will have the conditions necessary for the economy of motive power. Let the canal be provided with a sluice, and waiting until the tide has risen to a certain height, say two feet, let the sluice be opened, and the water let in, in such quantity that it shall rise in the reservoir as rapidly as the tide rises outside. Hence, through the period of the in- flux of the tide there will be a current through the canal, with a head of two feet. Finally, the reservoir tills to the same height as the sea outside. Then let the sluice be closed, and remain closed, until the tide has fallen two feet. On opening the sluice the water of the reservoir flows out with a head of two feet, and will continue until the tide is out ; the reservoir will then empty itself, and be ready for repeating this opera- tion the next tide. Now let us consider how this is circumstanced as to time. We may take the duration of a tide as twelve hours twenty minutes, and as the tide in average rises and falls twelve feet in that time, the mean rate of motion of the tide, in height, is found to be one foot in thirty-one minutes. We may take half an hour to a foot without sensible error. Now the tide being out, the sluice must be closed for an hour, in order to allow the water outside to get the head of two feet, with which it has to work. On opening the sluice, it will then flow into the pond, and so continue for five hours, when the tide will be fully in. The reservoir being then allowed to fill completely, for which there is ten minutes available, with additional sluices, the canal is to be closed for an hour, until the sea outside shall have fallen two feet. On opening the sluice the water will issue for five hours, with a two foot head, and then, by the extra sluices, the remaining water of the reservoir may be got rid of in ten minutes, so that it shall be ready to begin again. The current is thus, with two feet head, for five hours on the rise, and five hours on the fall of each tide ; that is for twenty hours out of the twenty-four. Let us now calculate the the- oretical power of this current. As a standard reservoir we shall take the area of an acre. When the tide is fully in, the water in the reservoir shall be as deep as the tide rises, that I 114 INDUSTRIAL RESOURCES is twelve feet. Of this, however, the two feet tiiat entered last is supposed not to have been mechanically employed. The water of the reservoir which may be used as power is, there- fore, ten feet deep. The acre contains consequently 435,600 cubic feet of water. This quantity passes in twice, and passes out twice, in every twenty-four hours ; that is, in the twenty- four hours there are available, 48,400 tons of water falling through two feet. Now as 884 tons falling twenty-four feet in twenty-four hours is a horse power, it follows, that the the- oretical power of the tide, used with two feet fall, is four one- half horse power for each acre of reservoir, in which the depth of the water is equal to the height of rise of the tide. Hence, ten acres of reservoir should give a theoretic force of forty- five horse power for twenty hours out of the twenty-four. Now if this were as in an ordinary stream, nothing could be more simple than the erection of an undershot wheel, which, economizing one-third of the theoretic power, should deliver one and a half working horse power for each acre of reservoir. But it is easy to observe two circumstances which render the construction of tide-mills more complicated, and their applica- tion more difficult. In fact, the current of water changes its direction every six hours, as the tide runs in and out. This, however, is easily met by mechanical contrivances of various and simple kinds, by which the direction of action of the cur- rent is altered, when its own direction changes, so that the motion transmitted to the machinery remains the same. This, therefore, is not a real difficulty, although it introduces some additional mechanism. But it is more important to consider, that as the level of the tidal water is continually changing, at the rate, indeed, of two feet in height per hour, the machinery capable of acting at the lower levels of the tide, should be totally submerged at the upper; particularly if in place of the average rise and fall, which we have taken at twelve feet, we consider the rise and fall at springs, which we may esti- mate at eighteen feet upon our coasts. From this comes the greatest difficulty in managing tide-mills. It is, however, surmounted in cither of two ways, which I shall but briefly notice. OF IRELAND. 115 In the first the force of the water is applied to bear up the wheel itself, so that it shall constantly float, rising and falling with the tide. This object has been eifected, by letting the pressure of the water act on a water-tight frame, within which the whole mechanism of the wheel is contained. It has been also done by making the extremities of the axle of the wheel rest on the pistons of an hydrostatic px-ess, into which water was injected by the wheel itself. All these means ai'e quite practicable ; they are not expensive, but they are troublesome, and the necessity for them has probably been the principal cause of the neglect into which the tide-mill has fallen. The second means of compensating for the change of level in the water consists in employing peculiar forms of wheels, of which many kinds have been proj)Osed, which work even submerged, or, at least, admit of being partly submerged without their power being all destroyed. Such wheels have been described by Belidor, Barlow, and other writers, but I shall not delay upon them. They have the merit of turning round when almost drowned, but they have the fault of not being able to do any im- portant proportion of work. The loss of power in such wheels is so great as to negative their practical employment. It is thus easily seen, that I do not strongly recommend those tide-mills, which are at present known, whether they work nearly submerged at a constant level, or that they change their level by the aid of complex machinery. I should not, in fact, direct attention to the tidal waters as an important som*ce of power, but that there has been recently invented a machine, which, I conceive, renders them truly available. It is the tur- bine, already noticed under another point of view. The acting force in the turbine is proportional to the difference between the pressure of the water inside and outside of its cylinder. It is no matter how deep it may be under water, provided this difference is kept up. It works with the same effect ; delivers out in practice the same per centage of the theoretic power, and hence realizes absolutely the conditions necessary for the perfect utilization of the motive power of our tides. If, re- tm-ning to the example of canal and reservoir, which I already I 2 116 INDUSTRIAL RESOURCES employed, there was placed behind the sluice a turbine, and the water let on at the head of two feet, the turbine would de- liver out practically two-thirds of the calculated force, at least, and continue to do so all the time that the rise or fall of the waters continued. The mechanical arrangements for the change of direction of rotation, for conducting the water to and from the top and bottom of the machine, are such as mil present themselves to the mind of every mechanical engineer, and would be of too purely technical a character for me to no- tice here. The turbine is, therefore, peculiarly the machine for econo- mizing tidal power. For each acre of reservoir it may be ex- pected to give at least three horse power, working twenty hours out of the twenty-four. In average for thirty-three acres of reservoir, on which the flood rises in average twelve feet, a working efficiency of 100 horse power may be calculated on. Now let us consider how many situations on our coasts there are, where flats left bare by the retreating tide, and covered many feet deep with water on its return, are utterly useless in their present state, but only require an embankment easily and cheaply constructible, to be converted into reservoirs for setting tide- mills at work. How many places are there, especially on our eastern coast, where reservoirs of vast size appear, indeed, as if presented by nature to tempt man to enterprize, leaving but little for him to do. Ballyteigue, Tacumshane, and the adja- cent bays on the Wexford coast, are examples of such in- lets ; narrow at the mouth ; capacious inside ; formed as if laid out by a skilful engineer. But in some such cases the tides, being complex from local causes, counteract the advantages of their form. The inlets along the shores between Dublin and Drogheda present also many similar cases, though not so curiously affected in adaptation. The areas included between the Kingstown Railway and the shore, may serve to exemplify the facility of embanking such reservoirs, and the tidal cur- rents by wiiich they are filled and emptied. I shall not at- tempt to calculate tiie mechanical power that migiit be created in those situations ; I siiall leave it as a useful exercise to OF lEELAND. 117 those, of whom I hope there are many, who may be led by what I have now stated, to think and examine for themselves, and to apply the bases of calculation which have been given in this and the preceding chapters to those instances, and to such others as their own observation may bring before them. 118 INDUSTRIAL RESOURCES CHAPTER IV.

INFLUENCE OF THE COST OF FUEL ON THE IRON MANUFACTURE. RECENT PROCESSES FOR ECONOMIZING THE AVASTE HEAT OF IRON FURNACES. UTILIZATION OF FUELS OF INFERIOR QUALITY. In the preceding chaptci* 1 have endeavoured to establish the conditions, under which are found in Ireland two elements, es- sential above all others to the prosecution of manufacturing industry, fuel and power, and to analyze the relation, which the cost of motive power in mechanical operations, bears to the other circumstances. There remain for examination, however, other subjects of not inferior interest or importance, and of these one will specially require a detailed notice, as it affects the industrial arts almost in an equal degree with the cost of fuel. I shall, therefore, endeavour to represent in the following no- tice, the circumstances under which this country is placed with regard to the supply and maiml'acture of in ni. This metal is, indeed, indispensable to an advanced condition of tiie arts. If we employ fuel to give motion to our machinery, we as inevita- OF IRELAND. 119 bly employ iron in the construction of the machine. Its various properties adapt it to oiir uses in an unparalleled degree : as we require massive strength or delicacy of form, whether we wish our material to be rigid or highly elastic, hard or soft, iron is that which satisfies our wants ; fusible in one condition, infusible, but highly plastic in another, it is capable of being moulded, welded, turned, ground, and polished ; whilst by the wise economy of nature, fortunately for man, being found in every country, and available at a small expense, its supply is practically unlimited. Its use has hence become at once the cause and measure of material progress. A nation without iron cannot emerge from the condition of semi-barbarism. Its chiefs may be magnificent in gold and jewels ; its wari'iors may be armed with shields and swords of bronze, on which the la- bour of long practised workmen may bestow a finish, admira- ble even at the present day ; but the rarity and cost, as well of material as of artificer, dei3rive the general population of all power to render those precious metals available to their domestic comfort. It is only where iron is obtainable ; where, cheap and abundant, it places within the reach of all, the means of constructing the various tools and instruments by which the arts and agriculture are so materially advanced, that civilization can become firmly grounded amongst a people. If we consider how each succeeding step in industry places the elements of material domestic comfort more cheaply in the power of a people ; that by this greater cheapness and facility of procuring the means of animal existence, there is afforded time for mental cultivation, and growing out of that, by pro- per discipline, a sounder morality, a love of peace and justice, we may well recognize in coal and iron, agents of civilization and of intellectual happiness toman, of whose powers, astound- ing as they appear, we trace but the infant energies — of whose final results we can no more apply a measure, than could the savage, who, sensible of the value of the tool, barters his golden ornaments for a knife, estimate the industrial and educational movements of the present day. The variety of properties which fits iron so wonderfully for its uses in the arts, is the foundation also of a variety in its 120 INDUSTRIAL RESOURCES money value, which I shall here notice, as it will be found to affect, in a very material degree, the circumstances of this country as to its manufacture. In fact, so cheaply is the metal itself obtained, that its subsequent adaptation to different uses demands a degree of mechanical skill and labour which over- shadows totally the cost of the iron employed ; and hence, in the following table, selected from results given by Babbage and Friedenberg, the increase of value is for the most part made up of the cost of labour bestowed upon the article in the various processes it passes through. The quantity of cast iron worth £1 sterling becomes worth the following sums, when converted into Ordinary machinery, £^ Larger ornamental work, 43 Buckles, .

Knives (table), 36 Needles, 71 Penknife blades, 657 Polished buttons and buckles, .... 897 Balance springs of watches, .... 50,000 Some centuries ago Ireland presented a picture of manufac- turing industry, such as we would now find, perhaps, in the interior of Russia, or the mountainous districts of northern Spain, but which the progress of the arts has banished from Britain and from central Europe. Covered with forests, and possessing iron ore, as we shall hereafter shew, of the highest purity in great abundance, Ireland was sprinkled over with small iron works, in which the wood charcoal was employed, and thus iron manufactured of excellent quality ; in fact, such as we now import from Sweden and Russia for all the finer pur- poses of cutlery and mechanism. Such kinds of iron furnaces may be considered as now belonging but to the history of art ; OF IRELAND. 121 yet in an historical point of view it is not uninteresting to ex- tract some particulars of this industry amongst ourselves, from the remarkable work on the natural history of Ireland, written by Dr. Boate two centuries ago. " Of the iron mines there are three sorts in Ireland, for in some places the oar of the iron is drawn out of moores and bogs, in others it is hewen out of rocks, and in others it is digged out of mountains : of which three sorts the first is called bog- mine, the other rock-mine, and the third with several names, white-mine, pin-mine, and shell-mine. " The first sort, as we have said, and as the name itself doth shew, is found in low and boggie places, out of the which it is raised with very little charge, as lying not deep at all, com- monly on the superficies of the earth, and about a foot in thick- ness. This oar is very rich of metal, and that very good and tough, nevertheless in the melting it must be mingled with some of the mine or oar of some of the other sorts : for else it is too harsh, and keeping the furnace too hot, it melteth too suddenly, and stoppeth the mouth of the furnace, or, to use the workmen's own expression, choaketh the furnace. " The second sort, that which is taken out of rocks, being a hard and meer stony substance, of a dark and rustle colour, doth not lye scattered in several places, but is a piece of the very rock, of the which it is hewen : which rock being covered over with earth, is within equally every where of the same sub- stance ; so as the whole rock, and every parcel thereof, is oar of iron. This mine, as well as the former, is raised with little trouble, for the iron-rock, being full of joints, is with pick-axes easily divided and broken into pieces of what bigness one will: which by reason of the same joints, whereof they are full every where, may easily be broke into other lesser pieces ; as that is necessary, before they be put into the furnace. "Of this kind hitherto there hath but two mines been dis- covered in Ireland, the one in Munster, near the town of Tal- low, by the Earl of Cork's iron works ; the other in Leinster, in King's County, in a place called Desart land, belonging to one Sergeant-Major Piggot, which rock is of so great a com- pass, that before this rebellion it furnished divers gi-eat iron works, and could have furnished many more, without any nota- 122 INDUSTRIAL RESOURCES Lie diminution ; seeing the deepest pits that have been yet made in it, were not above two yards deep. The land, under which this rock lieth, is very good and fruitful, as much as any other land thereabouts, the mold being generally two feet and two and a half, and in many places three feet deep. " The third sort of iron-mine is digg'd out of the mountains in several parts of the kingdom ; in Ulster, in the county of Fermanagh, upon Lough Earn ; in the county of Cavan, in a place called Doubally in a dry mountain ; and in the county of nether- Tyrone, by the side of the rivulet Lishan, not far from Lough Neagh ; at the foot of the mountains Slew-galen, mentioned by us upon another occasion, in the beginning of this chapter: in Leinster, in King's County, hard by Mount- mellick ; and in Queen's County, two miles from Mountrath : in Connaught, in Tomound, or the county of Clare, six miles from Limerick ; in the county of Roscommon, by the side of Lough Allen ; and in the county of Leitrim, on the east side of the said lough, where the mountains are so full of this metal, that thereof it hath got in Irish the name of Slew Nerin, that is, mountains of iron : and in the province of Munster also in sun- dry places. " This sort is of a whitish or grey colour, like that of ashes ; and one needs not take much pains for to find it out, for the mountains which do contain it within themselves, do commonly shew it of their own accord, so as one may see the veins thereof at the very outside in the side of the mountains, being not very broad, but of great length, and commonly divers in one place, five or six ridges the cue above the other, with ridges of earth between them. " These veins or ridges are vulgarly called pins, from whence the mine hath the name of pin-mine ; being also called white- mine, because of its whitish colour ; and shell-mine, for the following reason; for this stuff or oar being neither loose or soft as earth or clay, neither firm and hard as stone, is of a middle substance between both, somewhat like unto slate, com- posed of shells or scales, they which do lio one upon another, and may be separated and taken asunder very easily, without any groat force or trouble. This stuff is digged out of the ground in lumps of the bigness of a mans head, bigger or less OF IRELAND. 123 according as the vein affordeth opportunity. Within every one of these lumps, when the mine is very rich and of the hest sort (for all the oar of this kind is not of equal goodness, some yielding more and better iron than other), lieth a small kernal, which hath the name of hony-comb given to it, because it is full of little holes, in the same manner as that substance whereof it borroweth its appellation. " The iron coming of this oar is not brittle, as that of the rock-mine, but tough, and in many places as good as any Spanish iron." It would be difficult at the present day, independent of che- mical analysis, to furnish a better description than that given two centuries ago by Boate, as just quoted, of the bog-iron, which is found in patches in almost every part of this island, and of the ironstone; of which the very rich quality of Lough Allen, and that of the Leinster district, was even then recog- nized. I shall return hereafter to the question of their com- position, but before leaving Dr. Boate I shall extract his account of the financial condition of the iron trade in Ireland, as it will shew the difference between the cost of manufacture then, and in the present day. " To speak somewhat more particularly both of the charges and profits of these iron-works, we shall instance the matter in one of the works of the said Sir Charles Coot, namely that which he had in the lordship of Mountrath, in Queen's County. At that work the tun (that is twenty hundred weight) of rock- mine at the furnace head came in all to stand in five shillings and six-pence sterling, and the tun of white mine, which he had brought him from a place two miles further off, in seven shil- lings. These two were mixed in that proportion, that to one part of rock mine were taken two parts of white mine : for if more of the rock-mine had been taken, the iron would not have been so good, and too brittle ; and being thus mixed, they yielded one-third part of iron ; that is to say, of two tuns of white-mine, and one of rock-mine, being mingled and melted together, they had one tun of good iron, such as is called mer- chant's iron, being not of the first, but second melting, and hammered out into bars, and consequently fit for all kinds of use. 124 INDUSTRIAL RESOURCES " This iron he sent down the river Oure (by others called the Nure) to Rosse and Waterford, in that kind of Irish boats which are called cots in that country, being made of one piece of timber: which kind of ill favoured boats (mentioned also by us above) are very common throughout all Ireland, both for to pass rivers in, and to carry goods from one place to another ; and not only upon shallow waters, such as the aforenamed river is, in the greatest part of its course, but even upon the great rivers and loughs. " At Waterford the iron was put aboard of ships going for London, where it was sold for sixteen, othcrwhiles for seven- teen jjounds sterling, and sometimes for seventeen and a half; whereas it did not stand Sir Charles Coot in more than betwixt ten and eleven pounds sterling, all charges reckoned, as well of digging, melting, fining, as of carrying, boat -hire and freight, even the custom also comprehended in it. " In most of the other places did a tun of the iron-mine or oar come to stand in five, five and a half, and six shillings ster- ling at the furnace head ; and it was an ordinary thing, as well where they used white-mine, as where they mixed rock-mine with it, to have a tun of good iron out of three tuns of oar : in some places, where the mine was richer, they would have a tun of iron out of only two tuns and a half of oar. Nevertheless few of them gained more or as much as Sir Charles Coot, be- cause they had not the same conveniency of transportation ; and he himself did not gain so much bj^ his iron works in Con- naught, as by that near Mountrath, although the mines there afforded a richer oar, and that the tun thereof, did cost him but three shillings at the furnace, because that Lough Allen, whereunto the same mines and works are contiguous, gave him the opportunity of can-ying the oar by water from the mine unto the work, and that in boats of forty tuns. " The Earl of Cork, whose iron works being seated in Mun- ster, afforded unto him very good ojiportunity of sending his iron out of the land by shipping, did in this particular surpass all others, so as he hath gained great treasures thereby : and knowing persons, who have Jiad a particular insight into his affairs, do assure me, that he hath profited above one hundred thousand pounds clear gain by his said iron works." OF IllKLAND. 125 We thus see that two hundred years ago iron was an article of export from Ireland to London. In fact, as well in Ireland as in England, where, at the same time, the same processes of manufacture were followed, the vast quantity of wood consumed, to make charcoal for the iron works, gradually stripped the country of its forests, and with the supply of fuel, of course the working of iron was aban- doned. Similar causes are at the present moment in operation on the Continent of Europe, and limit the economic manufac- ture of iron by means of wood, to those countries in which a thinly scattered population admits of large tracts being occu- pied in growing timber. The wonderfully fortunate destiny of England, however, intervened at that very time, when her iron trade was in process of rapid annihilation. The energy and genius of one man, to whose name the deserved honour has never yet been paid by England, rescued her from be- coming a mere dependant for iron on the north of Europe, and by inventing the process of reducing iron by means of coke, made the first step in the path of technical discovery which rendered that country the industrial sovereign of the world. It would not be difficult to shew, that had not Dudley substi- tuted coke for charcoal in smelting iron, the conditions of in- dustry which gave field for Watt and Arkwright, could scarcely have existed. In Ireland there was no man like Dudley. The iron manufacture in England assumed a new and enlarged ex- istence. The iron manufacture of Ireland rapidly declined, and finally, a centm-y ago, in Kerry, the last charcoal furnace was extinguished, when they had burned out the last remain- ing wood. It is necessary now to examine, with all the aid which modern science, and the experience of other countries, may afford us, how the materials necessary for the manufacture of iron are circumstanced with us. The ores of iron that are actually employed as sources of the metal are of three kinds, the anhydrous peroxide, or specular iron ; the hydrous peroxide, including hematite and bog ore ; and the carbonate of iron, to which the clay-ironstone of the coal formations belongs. Of the first kind of ore, there is but one locality in which it 126 INDUSTRIAL RESOURCES has hitherto become of industrial importance, the island of Elba, which has been celebrated from the earliest ages for the goodness of its iron and steel, obtained by the working of this ore. It is the richest ore of iron that is known, containing 70 per cent, of metal ; but as it cannot be smelted on the spot, it has been rendered unimportant by the superior economy of working inferior ores in more suitable localities, and the cele- brity of Elba as a source of iron is now but a fact in history. To us this ore is not without interest nevertheless. It has been found, and in some quantity, in the south of Ireland. I possess excellent specimens from the Cosheen mines at Skibbe- reen, and from the Glandore mines in Carberry. It is there associated with ores of copper and of manganese, which being of far greater value, the iron ore is not looked after : but it might be of considerable use to mix with the poorer oi'es of other districts, should circumstances ever justify the practical development of iron working in Ireland. The second kind of ore is of more practical importance, being probably the most extensively diffused of all the com- pounds of iron. It presents itself under a great variety of forms, according to the rocks with which it is associated, and the circumstances under which it has had its origin, and hence furnishes to the mineralogist a number of species, the detailed description of which I need not enter upon. When quite pure this ore is a hydrate of the peroxide of iron, in which the oxide contains twice as much oxygen as the water, having the for- mula, 2Fe2 O3 -j- 3 HO, and containing : Iron, 600 Oxygen, 25-6 Water, 144 100 Various forms of it support the majority of the iron furnaces of France and Germany. In England it is not employed, ex- cept to bring up, by its richness of produce, the poorer ores of the coal districts, to the standard at which their working be- comes most easy. The forms of it requii-e notice as to their composition and distribution in Ireland. These are the brown OF IRELAND, 12? nodular hematite, and the ochrty or bog iron ore. In the pure state it is but rarely found, and is tlion associated with the specular iron, and with other ores in the rocks of the older for- mations. It is hence not smelted by itself. The brown iron ore is found in abundance associated with the beds of coal and fire-clay, and the ordinary ironstone, in the coal district of Tyrone. I have examined specimens of it, not picked, but taken at random from heaps of it thrown out of the pits, and which may, therefore, represent its usual quality. It is the variety termed popularly cayle-stone, and forms globular masses of a deep brown colour, which are generally hollow, and contain a kernel of a lighter colour than the exterior, with which, however, it agrees in constitution. The specimens I analysed yielded : Peroxide of iron, 80*79 Water, 11 -97 Magnesia, 0-27 Insoluble matter, 5 "81 Oxide of manganese, 1*16 10000 This ore should hence have given by appropriate treatment 57 of iron per cent., or from 35 cwt. of ore a ton of iron. Of the similar ores actually employed upon the Continent, there are scarcely any materially richer than this. The follow- ing numbers shew the composition of the principal French and German ores of this class : FRANCE. Gt.BM.AHY. l'aude. ALLKVARD. STYKIA. CARINTHIA. Peroxide of iron, . . Oxide of manganese.

We find in almost every deep morass, beds of it, sometimes a foot thick. It is hence called bog iron ore. This ore supported the majority of the small iron furnaces formerly scattered over the surface of this coun- try. It appears as a brownish clay, which dries to a mass, sometimes dense and hard, at others friable, and becomes much darker in colour when it dries. Its origin appears to be con- nected with the former existence of tribes of minute animals, of which the fossilized remains may be detected in it by the mi- croscope. This also explains a fact in its composition which seriously affects the quality of the iron obtained from it, the presence of phosphoric acid, and there occurs also black oxide of manganese, sometimes in such quantity that it might as well be called an ore of manganese as of iron. The bog iron ore of Ireland has not yet been analysed, but I annex the composition of three foreign specimens, in order that the nature of this mineral may be shewn. SCHLESWIG. DAMMEROW. POMEUAKIA.

They are at once very fusible and easily reduced. They pro- duce a metal whicii runs very thin and congeals slowly, so that it is propir for the manufafturo of cast iron articKs which do OF IRELAND. 129 not require much strength. As all the phosphorus of the ore passes into the metal, this is sometimes very fragile. The Ber- lin ornaments, which as specimens of casting, and as objects of art, excite so much admiration, are made of iron smelted from the bog iron ore of the vast morasses of the east of Prussia: analyses of two of these ores are amongst those just now given. I have not been able to ascertain the extent to which this ore of iron may now exist within our bogs ; nor do I consider it a question of much importance, as it will be hereafter seen, that ores of much richer character, and yielding a purer metal, are so abundant, as to render the bog iron ore merely an object of curiosity to us. The substitution, by Dudley, of coal coke for charcoal in the manufacture of iron, created a revolution, not only in the kind of fuel, but in the kind of ore employed, and indeed in the lo- calities where the manufacture could advantageously be car- ried on. Before that time, the minerals employed were the various kinds of hematites, more or less pure, such as we have in Tyrone, and the bog iron ores ; but it was found, that in almost every coal district there occurs an ore of iron, quite different from those, and which is now known as clay-ironstone. The richness of this ore varies very much, but being found in immediate proximity to the fuel, and still more the coal beds presenting various other mineral materials of use in the manu- facture, it was found more advantageous to smelt it than to bring either richer ores from a distance to the fuel, or the fuel any distance to the richer ores, and hence the iron manufacture was located, and has since remained, in the coal districts of Great Britain, which the superior economy of its processes and of its materials will probably maintain as its head quarters for numerous ages to come. In fact, the manufacture of iron requires a variety of ma- terials, which it would be very expensive to bring together, did their sources lie at considerable distances, and hence the cost of the metal produced should be considerably higher, and thereby its extent of use and of manufacture limited in propor- tion. But by an organization of nature, of which it is impos- sible to exaggerate the wisdom and the importance to mankind. 130 INDUSTRIAL HESOURCES the coal measures rest upon, and contain beds of hard and in- fusible sandstone, of -which the most refractory portions of the furnaces may be built. The coal rests usually on clay, of which the best tire-bricks may be formed ; dispersed in layers through the slate which covers the coal, is found in abundance the iron ore, whilst the limestone necessary as a flux, lies on the edges of the coal basin, Avhere the underlying calcareous strata come to the surface. Now this combination of sandstone for hearths, clay for crucibles and for bricks, lime for flux, ore and coal for smelt- ing, is not restricted to any one coal district. The same is found in England and Wales, the same in Scotland, and in fact, were any one of those materials absent or difficult to be pro- cured, the economic manufacture of the metal would be im- possible. A knowledge of these circumstances is necessary, that we may compare the means which we possess in Ireland for making iron, with those of other countries. That there is ore is cer- tain, that there is fuel is certain, but if the ore, the fuel, the clay, and all the other conditions do not conspire, the economic manufacture becomes impossible, and an attempt would only ruin those who unadvisedly engaged upon it. The clay ironstone which has thus become almost the ex- clusive source of iron to Great Britain, occurs in groat abun- dance in this country, in the coal districts of Leinster and of Connaught ; it is not of the same quality or appearance in both, and as the diff^erence is not without importance in its ap- plication, it will be necessary to notice each in turn. It will hence be easily understood, how, in order to trace the localities of the clay ironstone, it is necessary to revert to the description of the coal formations given in a former chap- ter, and indeed to complete their history by an account of the ores of iron which they contain. I shall, however, only enter into detail with regard to two of those districts, those of Con- naught and of Leinster, as the other coal districts do not ap- pear to me to present any features sufficiently promising in relation to iron to render them important. In the Leinster district a succession of beds of slate, sand- OF IRELAND. 131 stone, and clay, are associated with the coal, according to an order which has been very perfectly illustrated by the Reports of Mr. Griffith already noticed. The clay ironstone occurs abundantly in nodules disseminated through the layers of slate, from which they separate spontaneously by weathering, or are easily detached. The total thickness of this slate is estimated at 239 feet, distributed in eight beds. Its characters are re- presented by those given in the following words of Mr. Grif- fith's description of the second bed from below. Its thickness was thirty feet. " Spheroidal slate-clay, containing balls of clay ironstone frequently one foot in thickness. By spheroidal slate-clay is meant a species of hard slate, which on being exposed to the atmosphere, divides into large flattened spheroids ; on being struck the outer coat comes off, and leaves a smaller spheroid, which being again struck, a second concentric coat is separated, and so on until the nucleus is met with, which sometimes is composed of hard claystone, and sometimes of clay ironstone. The ironstone contained in this bed is very rich, and in many places remains of ancient excavations are still visible, where this bed has been wrought in search of ironstone, and indeed some of the iron furnaces may be seen." All the other beds assimilate to this in character. The quan- tity of ironstone present is of course in proportion to that of the rock in which it is disseminated ; its quantity may be in- ferred from the results of borings given by Mr. Griffith. Thus in a deep bore-hole at Massford, down to the four foot coal, where the total depth was sixty-eight yards, the layers of pure ironstone amounted to thirty-eight inches, and the strata were found to be constituted of Sinking to rock, 8 yards. Sandstone, 31 ,, Slate-clay, 25 „ Ironstone, 1 ,, 2 inches. Coal and kelve, 3 ,, GS yards. k2 132 INDUSTRIAL RESOURCES In a boring at Moncen Roc, near Massford, which oxtcnded eighty-four yards, six feet nine inches of pure ironstone were found. The strata consisting of Sinking by pit, 16 yards. Sandstone, 32 ,, Slate-clay, 31 ,, Ironstone, 2 ,, 9 inches. Coal and kelve, 3 ,, 84 yards. It is necessary to describe more specially the properties and composition of this ironstone. Specimens presented to me by Mr. Wandesford, from his collieries at Castlecomer, gave the following I'esults : The colour is dark gray when fresh, but becoming rust co- loured by long exposure to the air. The specific gravity is about 3*250. When ignited it loses 29 per cent, of its weight, and the residue is strongly attracted by the magnet. Two different specimens analysed, gave the following results : No. 1. No. 2. Protoxide of Iron, 5108 48-03 Lime, "16 1"51 Magnesia, 1*05 4-24 Alumina, 1"86 1'45 Insoluble matter 1392 16-17 Carbonic acid, 31-93 28-60 10000 10000 Of these ores No. 1 contains 39-7 per cent, of iron, and No. 2 37 "6. As they were not selected for analysis on accoimt of any apparent superiority to other specimens, they may pro- bably represent the ordinary run of the ironstone of the Leins- ter district. The supply of the iron ore in this district is not limited to the clay slate lying deep among the coal strata. The other sources of it are thus described by Mr. Tighe in his Survey of the county of Kilkenny : " We have already seen that the slate &e IRELAND. 133 covering the collieries contains nodules of iron ore, and this ore is very heavy and rich, but some of the best iron mines lie open to the surface, and form the upper strata of entire hills. Hills of this kind run in a north-east direction from Lady Or- mond's demesne towards the colliery. On the lands of Agha- mucky is a hollow road cut to a great depth through a rich mine of iron ; from this place the ore was formerly carried to be smelted at Mountrath, in the Queen's County, as long as the timber lasted in that neighbourhood." The i-ichness of these ores may be inferred from the account of Boate, that when the ore was good, two and a half tons of it gave a ton of iron, but in common, one ton for three was expected. The abundance of ironstone found in the Connaught coal dis- trict gave origin to several works for the reduction of the metal at that early period, when the extensive woods supplied charcoal for the furnaces ; and almost without intermission, since the invention of the method of smelting by means of coal and coke, attempts have been made at various times, and by different individuals, to carry on iron works in that locality. These attempts have hitherto failed, owing to circumstances, of which most were of a nature purely personal, and cannot be noticed here. Other sources of failure were connected with the conditions of the manufactures and of the locality itself, and it will be in another place important to trace and illustrate those, in order that we may judge whether the difficulties, be- fore which so many have sunk, are in themselves really insur- mountable. It is necessary first to describe the composition and distri- bution of the ore. On the eastern shore of Lough Allen rises the Iron Moun- tain (Slieve-a-Nierin), a hill of considerable elevation. It con- sists of alternate beds of sandstone and slate-clay resting upon the basis of the upper limestone. The great bed of slate-clay varies from 300 to 500 feet in thickness ; others are of different but lesser magnitude. In this clay the nodules of ironstone are disseminated in abundance ; and the rains, washing away the softened and decomposing clay, the balls of ore are carried down to the shore of the lake, whence, and from the beds of 134 INDUSTRIAL RESOURCES the rivulets, they are collected by the peasantry and brought to the works for use. At the base of this mountain, on the eastern side of the outlet of the lake, lies Drumshambo, where this ore was formerly smelted. I shall hence designate this ore from the eastern side of the basin as Drumshambo ore. In purity it is somewhat superior to that which is found on the western side. The southern and western division of this coal field is popu- larly known from the River Arigna, which is its northern bomi- dary, and whose name became notorious by the iron works established on its banks, the history of which has so fatally in- fluenced industrial enterprize in Ireland. The stratification of the mountain is similar to that of the opposite side ; resting on the limestone of the surrounding countrj% occurs the great bed of slate-clay, 600 feet in thickness, and containing nume- rous beds of ironstone, from half an inch to two feet in thick- ness. Their number is, as Mr. Griffith mentions, almost in- credible, but the most important occur from 200 to 300 feet above the limestone. The same eminent geologist describes the thin beds as being in most cases the best, but that of Alta- gowlan, which is a foot thick, was amongst the richest iron- stone Mr. Griffith ever saw. The usual form is that of nodules, in size from an egg to that of a bull's head ; but it forms also strata, or sheets of considerable extent. In many places the bed of the River Arigna, in its whole breadth, is formed of a flag of ironstone, which is often many perches in length. On this side of the lake also, owing to the weathering of the slate-clay, the nodules of ironstone are deposited in vast quantities in the beds of the mountain streams. Were the ore employed this source would soon become exhausted, and of course the beds of ironstone should then be worked in situ, as they are else- where, Mr. Twigg, whose observations on the Arigna district are the most recent, thus speaks, in his Report made to the Direc- tors of the Arigna Company in 1830 : " The ironstone mines have been examined, and the result found extremely favourable. A greater variety of ironstones I never met with, from which, by a proper admixture and proper managi'iuent, I have no OF IRELAND. 135 hesitation in saying, that pig-iron of best marks, and fit for foundry work of every kind, may be obtained. The iron mines begin in Rover, and continue for two miles and a half. I mea- sured several of the beds to more than two feet thick, in some places laid bare in the ravines, and in the bed of the Arigna river we can get any quantity at the shortest notice. There is enough to last two furnaces for 250 years." In quantity there is no doubt but that the ironstone of this tlistrict is practicably inexUaustible. In order to ascertain its quality, I have effected accurate analyses of numerous speci- mens of it, obtained from different portions of the district. Their detailed characters and composition follow : CLAY IRONSTONE NODDLES FROM ARIGNA No. 1. No. 2. No. 3.

Nos. 1 and 4 were absolutely free from that impurity. As none of these were picked specimens, the average of all of them may be fairly calculated as the material available on the large scale at Lough Allen, and the mean of the above five analyses gives : Protoxide of iron, 51 'SG Lime, 1*59 Magnesia, 1*92 Alumina, 0*98 Insoluble clay, 12-82 Carbonic acid, 31*33 lOO-OO and this contains 40 per cent, of metallic iron.

MM. Dufresnoy and Berthier have analysed the ores of iron worked in Staffordshire and in South Wales. Their results are briefly the following. In Staffordshire the thick, rounded nodules, having a black- ish grey fracture, are called yuhhins; these are rare. The usual OF IRELAND. 137 ore is in thin, flattened veins, bluish grey in colour, and is called blue-Jiat. These consist, in 100 parts, of BLUE-FLAT.

Protoxide of iron, 52'50 Lime, 2-66 Insoluble residue, 12"66 Carbonic acid, &c., 32*18 10000 This ore gives 40*5 per cent, of iron. Every thing which gives more than 20 per cent, of iron is reckoned as ore, but the price depends on the quality. Thus the gubbins are worth more than twice as much as the blue- flats. The following analyses give in a similar manner the compo- sition of the rich and usual kinds of the Welch ore : USUAL ORE. RICH ORE.

A series of accurate analyses of those ores has been made by Dr. Colquhoun, of which the most important are subjoined. 138 INDUSTRIAL RESOURCES CROSS BASKET IRONSTONE.

The ironstone of Kilkenny is but little inferior to that of Arigna, whilst the ores of Lough Allen attain a richness in iron, only equalled by the black hand ironstone of Glasgow. It is necessary, however, to trace further the conditions of the iron manufacture in these districts, for, as has been already mentioned, such is the economy required in this department of industry, that unless there be upon the spot all the materials to be used, the cost of obtaining them would be too high. Now in order to smelt and work iron, there are required building ma- terials for the furnaces, which must be formed of infusible sand- stone and of the most refractory bricks, for which fire-clay is necessary. These substances are found abundantly interstra- tified with the slate-clay and coal ; their detailed description will be given elsewhere, but their properties are such, as may be now assumed to present no obstacle to the manufacture. To flux the earthy material of the ore, lime must be added. This is in all cases accessible, as the whole coal field rests on lime- stone, which presents itself on every side within .short distances. Finally, the coal necessary for the smelting of the ore is deriva- ble from the same formation ; but as our coal beds are thin and limited in size, and hence more difficult to work than the larger beds of the British coal fields, it becomes a question whether the greater price of the coals in Ireland is not pi'ohi- bitory to the manufacture. In order to appreciate how far this acts, it is necessary to trace somewhat in detail the conditions of the smelting process, and the proportions of the materials used. The smelting of iron from the ore is accomplished in fur- naces of great size, generally termed high furnaces. Their dimensions vary ; the height is usually from forty to fifty feet ; the external form is that of a massive tower, the interior is di- 140 INDUSTRIAL RESOURCES vided into four portions, of different forms, and acting dif- ferently in the smelting process. The lowest is the hearth or crucible, formed of the most refractory sandstone of the coal field, built as a rectangular prism, and wdening at top into the second portion, which is built also of sandstone. From this the dimensions of the cavity rapidly expand, forming the lower body, or boshes ; this part of the furnace is conical, with its base upwards, on which the body of the furnace rises, consti- tuting about two-thirds of the entire height, and extending to the top, where it supports a chimney of about ten feet high. Near the bottom of the furnace are formed apertures, by which the pipes from the blowing machines are introduced, to force air into the furnace. These apertures are termed tuyeres. On one side of the hearth is the arrangement for opening, so that the melted metal may be run out as soon as a suitable quan- tity has collected, and also that the slags formed in the process may be discharged as they come down. Such being the structure of the furnace, the process followed is easily understood. The ore contains oxide of iron : the fuel contains carbon ; when these are heated together the oxygen unites with the carbon, and the iron is set free. The iron it- self combines also with some carbon, so that it assumes the state of metal or cast iron, in which, being fusible, it melts, runs down to the bottom, and accumulating in the crucible, is run off at certain intervals into moulds prepared on the floor of the apartment in sand, where solidifying, it forms the masses commercially termed pigs. It may have been remarked, how- ever, that the ore contains from 10 to 20 per cent, of foreign materials, su(;h as silica, alumina, magnesia, and that the fuel employed contains ashes from 5 to 15 per cent, of the same materials. These, at a high temperature, would react on the oxide of iron, and interfere with its reduction ; and also form- ing difficultly fusible clinkers would impede the descent of the fuel and ore, and disturb the progress of the operation. All this evil is avoided by the use of a certain quantity of lime. This, uniting with the silica and alumina, forms an easily fusi- ble slag, a kind of glass, which runs down into the crucible, where it floats upon the li(juid iron, and as it accumulates, OF IRELAND. 141 is run off through an aperture temporarily opened for the pur- pose. Before placing these materials in the high furnace, there are two preliminary operations performed. First, the calcining of the ore, and second, the cokeing of the coal. For these pro- cesses, as they involve the expulsion of a lai'ge body of volatile matter at a low heat, would, if carried on in the high furnace, produce such a cooling effect as might retard, if not stop, the work entirely. The mineral is broken into small pieces, and being mixed with some coal, this is set on fire and allowed to burn slowly. About 30 per cent, of the weight of the ore is thus driven off, consisting of carbonic acid, and of any water that it contained. The loss which the Irish ores suffered by calcination has been described already. It may be mentioned, however, that when the roasting takes place in the air, the iron is partially converted into peroxide, whilst, when it has been effected in close vessels, the residue contains the iron as black magnetic oxide, and carbonic oxide is evolved. The cokeing of the coal for the purposes of the ironfm'naces is accomplished by a partial combustion in great heaps, by means of such a limited supply of air, that little but the vola- tile portions of the coal is driven off. The quantity of coke produced varies, according to the quality of the coal and the care with which the process is conducted, being from 50 to 65 per cent, of the weight of the coal. The quantity and quality of the coke obtained from the different varieties of Irish fuel have been given already. Such being the general conditions of the process of smelting iron from the ore, it now remains to trace the elements of its money cost, and to apply the experience and results of other districts to the circumstances which prevail in Ireland. I shall, therefore, first briefly describe the estimates of cost of fabri- cating pig-iron in Staffordshire and Wales. The facts and numbers I shall give are derived from the Voyage Metallur- gique en Angleterre, published in 1837, by a commission of the most eminent French engineers. The market price of iron has changed very much since that period, but the cost of produc- 142 INDUSTRIAL RESOURCES tion has alterod but very little : certainly not in any degree to affect the conclusions we may draw. From an examination of the work of six high furnaces in the vicinity of Dudley in Staffordshire, it results that the average materials necessary to produce a ton of good pig-iron are : Coal, 3 tons, 16 cwt., 60 !b. Ore, 2 tons, 18 cwt., 100 lb. Flux, 13 cwt., 100 lb. The coal for roasting the ore, as well as that for making coke, is included ; but it is necessai'y to add the small coal used in the engine to drive the blowing machine. This may be taken at ten cwt. Now the prices of these materials are, Small coal, from 2s. to 3s. per ton. Coal for coke, from 6s. to 7s. per ton. It may be taken at 6s. The ores vary from 4s. to 10s. per ton, seldom falling below 7s., which may be taken as the average. Finally, it has been found, from an experience of several years, that the sundry expenses of labour, superintendence, interest, &c., incurred in producing a ton of pig-iron, are from 22s. to 23s. The cost of production is, therefore, as follows : Coal for roasting and cokeing at 6s. Ore ,, ,, at 7s. Limestone for flux, at Gs. . Small coal for engine, at 3s. . . Labour and general expenses, . £3 11 7 Mr. Aikin has given an account in the Technical Repository of the proportions used in Shropshire, which are, in order to form a ton of iron, 2 tons, 16 cwt. of ironstone; Or, 2 tons of roasted ore. 12 cwt. of coal for the roasting. 4 tons, 10 cwt. of coal for the furnace ; Or, 2 tons, 4i cwt. coke. 10:V limestone for flux. There is here much more coal used than in Sfaifordshire, £1 3 1 8 3 11 1 6 1 2 6 OF IRELAND. 143 where it is dearer. Mr. Aikin does not give the pecuniary es- timate of the process. In Wales the iron works are on a much larger scale than in Staffordshire, and most of the iron is made for I'efining into bars. These circumstances affect very materially the pro- portions of the materials, and the cost of production of the metal. At the great iron works ofCy-fartha, nearMerthyr, belong- ing to Mr. Crayshaw, the proportions and cost of the materials, and other expenses for producing a ton of iron, were, when the French Engineers wrote, as follows : 3 tons 10 cwt. coal, at 4s. per ton, . . £0 14 3 tons mineral, at 10s. per ton, ... 1 10 14 cwt. limestone, at Is. 6d. per ton, . 10 Labour, 12 Rent, 1 31 Management, 009 Repairs, &c., 010 £3 2i At Mr. Hunt's of Pontypool, for the ton of metal the mate- rial required and the cost were : 6 tons of coal, at 4s., £14 14 cwt. of small coal for roasting and en- gine, at Is. 6d., Oil 3 tons, 3 cwi;. of ore, at 7s., 12 1 15 cwt. limestone, at 2s. 6f/., .... 1 10 General expenses and interest, .... 110 £3 10 The coal used in these works is of bad quality, and hence the large quantity consumed. Finally, the following estimate shews the cost of production of iron at Abersichan, whei'e, however, it must be remarked, the cost of materials is but the mere cost of raising the ore and coal from the pit, as the mines are on the works them- selves. 141 INDUSTKIAL REaOTTUCEa Labour, £075^ Carriage of materials, 17^ Coal, 3 tons, 2 cwt., at 2s. 5d., ... 076 Ore, 2 tons, 17 cwt., 99lb, at a«. 6 so great a variety of jiurposes ; but the preparation of malleable iron from the pig metal requires additional processes, and the subject «ould riinain imperfect OF IRELAND. 155 were not the circumstances of these further branches of the manufacture of iron noticed. The change of pig-iron into bar requires thi'ee operations, viz., refining, puddling, and balling. This last is not imiver- sally practised ; but it is best to consider it here as being em- ployed. The refining is conducted in a small blast furnance, with a shallow rectangular crucible. The crucible is filled with coke, the pigs of metal are laid on it and covered up with coke, and the fire being lighted, and the air let on, the metal fuses, runs down into the crucible, and much of its carbon is disengaged as carbonic oxide gas. Some slags from other operations are added to save the crucible from being cut up, and often scoriae of iron from the forges, or hematite, or oxide of manganese, is added, which favour the elimination of the carbon from the metal, and diminish the loss which occurs. When the treatment of the metal has been completed, the Jiiie metal is rim out on a level surface of sand, so that it forms a thin plate, which is cooled rapidly by throwing water on it, and it is then broken and transferred to the puddling furnace. As an example of the proportions of expense of this process, the following abstract of the work at Verteg in South Wales may be taken ; it does not diff"er materially from Staffordshire. To produce a ton of fine metal it took 1 ton, 2 cwt., 1 qr. of pig at £3 6s., . . £3 13 5 14 cwt. of coal, at 4s. per ton, .... 2 10 Cost of cokeing the coal, 4 Cost of labour, made up of.

It appears to burn, the carbon which gave it its fusi- bility is gradually woi'ked out, and it becomes less liquid, and finally breaks into granules like sand. On increasing the heat, 156 INDUSTRIAL RESOURCES these agglutinate, and tlio workman, kneading them together with suitable tools, gradually works the entire into a mass, which taken from the furnace is already plastic and malleable. It is rolled into bars by being placed between grooved cylin- ders, made to revolve by a powerful engine, and these bars, if the iron be wanted of superior quality, are balled, by being heated in a reverberatory furnace still more intensely than in puddling, and many bars being welded togetner, and drawn out again by the roller, the highest degree of purity and homo- geneity is given to the material. The total cost of these processes, as carried on in Stafford- shire, was found by the French Commission of Inquiry to be, in the period from 1828 to 1837: To produce a ton of fine metal: 221 cwt. of pig, at £3 12s., £4 1 3 packs of coke, 041 Workmen, 014 Blast and management, Oil Repairs and sundries 11 Cost of a ton of fine metal, £4 7 6 To convert this fine metal into miU bar iron by puddling and rolling, there are for a ton of product : 22 cwt. of fine metal as above, .... £4 16 3 20 cwt. of coal, 056 10 cwt. of slack for engine, 14 Labour, viz..

On doing so in suitable proportions it is found that there are paid for 4 tons, 9 cwt. of ore at 7s., £1 11 3 8 tons, 6 cwt. of coal at 6s., 2 9 10 1 ton, 16 cwt. of slack at 3s., .... 036 Limestone per ton, 5 6 Labour, management and repairs, ... 2 17 6 £7 9 7 The total quantity of fuel consumed is therefore just ten times the weight of the bar iron produced, and makes 40 per cent, of the entire cost. It is hence easily intelligible how the iron manufacture naturally limits itself to the coal district. It must be recollected that the above estimates are derived from Staffordshire, where the cost of making iron is high, and were taken some years ago, when the cost of labour and ma- terials was much greater than at present. Thus the merchant bar iron would now be sold for about £6 per ton. And if we take a final estimate at the prices for which it has been already shewn that pig iron can be made at Arigna, considering labour and supei'intendance to be the same as in Staffordshire : 4 tons of ore at 5s., £10 10 tons of coal at 4s. 9rf., 2 7 6 1 ton of limestone, 2 6 Labour and general expenses, .... 2 17 6 £6 7 6 Thus merchant bar iron can be made at Arigna at the same price as it is now made in Staffordshire, and indeed cheaper, as 158 INDUSTRIAL RESOURCES the quantity of ore is calculated from the average of Stafford- shire, of 30 per cent., whilst Arigna ore yields 40 per cent, of iron. Hence 5s. might have been taken from the above esti- mate of cost. It is now necessary to pass to a branch of this subject which is of considerable importance to Ireland. The refining of iron by means of turf or turf charcoal, A few words will briefly point out its bearings. The iron which is smelted by means of pit coal always preserves a degree of impurity of constitution which reduces its strength and deteriorates its structure, so that for the finer purposes of machinery and of cutlery, Eng- land is indebted for much iron to Russia and Sweden, as in these countries, the smelting and refining being carried on by means of wood, the metal is obtained in absolute purity. Hence the great difference of price between the British and foreign iron ; common English bar being sold at £6 per ton ; whilst Swedish and Russian iron bars will cost £15, £25, or even £35 per ton, according to their quality. Now we possess in Ireland the means of preparing those irons of superior quality, and of replacing, if not the finest, at least the ordinary sorts of Baltic iron. The elements necessary to produce such metal are ores of great purity and a vegetable fuel of proper kind. The ores we have already seen to be abundant. The vege- table fuel is found abundantly in our turf. In England it can be easily understood that the manufacture of iron by turf is not thougiit worthy of notice. On the Con- tinent, however, where the promotion of native industry is an object of primary importance, and where the limited develop- ment of the coal districts obliges them to economize every source of fuel, it has been not merely tried, but is extensively carried on at present in France, in Prussia, and in Bavaria. These countries resemble our's in their relations to fuel, and it is by observation of what they do, that we may learn how to economize our own resources. I shall accordingly proceed to describe how turf is applied in the manufacture of iron abroad, and then endeavour to apply their residts to the peculiar cir- cumstances of Ireland. At Ransko, in Bohemia, there is an extensive iron work consisting of high furnaces for tlie smelting of pig-iron from OF IRELAND. 159 the ores ; of cupolas for the remelting of pig and making cast- ings, and the reverberatory furnaces and machinery for the manufacture of bar and plate. The ore that is employed is the clay ironstone, and is of very moderate quality. For fuel, is used a mixture of turf and charcoal. The turf is light, it is dried in the air, but not in any way prepared or pressed. The cubic metre of it weighs 225 kilos, and costs 1*34 franc. This is at the rate of 3s. per ton. The furnaces are blown with hot air at the temperature of 280° Fah. The proportions of ma- terials and products that are given from an average of long experience, is, that to make a ton of iron, there is consumed 34 cwt. 3 qrs. of turf, which costs 8s. 9d., and 30 cwt. of char- coal, costing 24s. 7d. The fuel for the smelting costs, there- fore, 33s. 4d., and the other expenses bring the total cost of the pig-iron to £3 13s. per ton. The fuel used in the cupolas and furnaces is the same, and the quality of iron is of the very highest character. At Konigsbrunn in Bavaria, are iron works peculiarly worthy of attention, as from the Report of the French engineers sent to examine them, it appears, that " they execute with tm'f alone the puddling and second fusion, reheating and roll- ing, finally, all the operations which are efPected with coal in the English furnaces." The turf employed is prepared with unusual care, as, owing to the excessively high price of fuel, every economy is impor- tant. It is not pressed, but is dried perfectly in stores of vai-ious kinds, of which two deserve especial notice. The first kind of store is heated by a fire-place belonging to itself. The other mode of drying the turf consists in an arrangement by which the waste heat of the various puddling and reheating furnaces is economized. The turf, as finally delivered at the furnace, is charged at the rate of 13s. per ton. It is of an average quality. Berthier found it to consist of Volatile matter ' 70*6 Carbon, 24*4 Ashes, 5-0 100-0 160 INDUSTRIAL RESOURCES and to give by ignition with litharge 143 times its weight of lead. The furnaces employed in these works all require peculia- rities of construction, arising from the bulk of the fuel being so much greater in proportion to its weight than when wood or coal is used. These peculiarities it would, however, be te- dious to describe here. They can be found on reference to the original memoirs and drawings ; it is only the results that are of importance to the immediate object of this work. It is found that in order to deliver a ton of puddled iron, there are required twenty-two and ahalfcwt. of pig, and there are consumed thirty and a quarter cwt. of turf, for which the densest is always selected. Of this puddled iron twenty-four and a half cwt. are reheated and rolled, vnth the consumption of thirty cwt. of dense turf, and the produce is a ton of small bars of iron of fine quality. The cost of manufacturing the fine bar iron by this turf is, therefore, per ton : 27^ cwt. of pig-iron, which is charged at £6 13.S. per ton, that being the selling price £9 14 Turf, at 14.S. per ton : 37 cwt. for puddling, i 2 7 6 30 cwt. for reheating, ) Labour and general expenses, .... 10 10 Cost of fine bars per ton, £11 19 8 Such are the financial circumstances of Ihe manufacture of iron in a country where there is really a scarcity of fuel, and •where the introduction of English iron is practically pro- hibited. I may add, that the consumption of turf has been found to be— For running a ton of iron in castings, twenty-one and a half cwt. of pig, and twenty-two cwt. of turf. For heating and rolling a ton of sheet iron, twenty-one cwt. of flat iron and thirty cwt. of turf. OF IRELAND. 161 In the iron Avorks of Ichoux, department of the Landes in France, no fuel is used in puddling but turf. The turf of mo- derate quality costs at the rate of 8s. per ton. The ton of puddled iron is given by twenty-two cwt. of pig, and forty-five cwt. of turf. M. Alex of Lauchhammer has substituted turf for coal in his puddling furnaces. It requires two and a half times as much turf as coal : the usual work being, that twenty- five cwt. of pig, worked up with twenty-six cubic feet of turf, gives twenty cwt. of iron rolled into bars. The perfect similarity of the charcoal of dense turf, and es- pecially of compressed turf, to that of wood, has been men- tioned in a former place. It has been tried as a substitute for wood charcoal in iron works, and with complete success. In the high furnaces of M. ftluller at Wendenhammer, wood charcoal has been replaced by an equal volume of turf charcoal, and this method has been so beneficial, that the quantity of ore worked off was materially increased. In the high furnaces of Wachter at Neunhammer, when half of the charcoal of wood was re- placed by turf coke, the charge of ore was raised from 3861b to 464tb. The quality of iron produced was excellent. Finally, MM. Moser and Wagner, who have examined minutely into the various conditions of this branch of industry, conclude, that both for smelting and refining iron, the coke of turf is as good and useful as an equal weight of wood charcoal. It is unnecessary to multiply quotations of evidence of this kind. The great fact which is to be recollected is, that turf and turf coke answer perfectly for making and refining iron, and from the quantities of materials and products, which the experience of the French and German workers has found to answer, and the cost of those materials, as we know they can be had with us, we may proceed to calculate what are the financial conditions of the subject. To produce a ton of pig-iron at Ransko, there are required thirty-five cwt. of turf and thirty cwt. of wood charcoal. Now for the latter may be substituted the turf coke, provided it be compressed ; and as the turf may be taken at 4s. per ton, and the coke at •20s., taking the ore and labour to be the same as M 1G2 INDUSTRIAL RESOURCES in our final estimate regarding the manufactui-e at Lough Al- len, mth coal, it becomes : 2J tons of ore, at 5s., £0 12 6 15 cwt. of limestone, at 2s. 6(Z 19 35 cwt. of turf, at 4s., 7 30 cwt. of turf coke, at 20s., 1 10 Labour and general expenses 12 6 Total cost of a ton of pig, £3 13 9 Such iron should, however, not be sold as mere pig or used in castings. Its fine quality would peculiarly fit it for being made into bars : now the Konigsbrunn results enable us to see what those bars should cost in Ireland. The calcidation is : 27^ cwt. of pig made as above and costing £3 6s. 3rf. per ton, £4 11 1 Tiu-f, at 4s. per ton : 37 cwt. for puddling, | 13 5 30 cwt. for reheating, J Labour and general expenses, for which, in order to avoid an error in deficiency, I will take double the German cost, . . 118 £6 6 2 Hence the ton of charcoal iron in bars would be made for six guineas. Now the price of the foreign charcoal iron ranges from £15 to £35 per ton. It cannot be made in England, for the wood charcoal is £4 per ton in the Forest of Dean, where some little remnant of the manufacture lingers. They have no extensive peat deposits. If they boast of their greater ex- tent of underground repositories of fuel, we may point to our's which lie upon the surface. We must learn, however, to em- ploy them i)roperly, and with economy, or else we would shew ourselves utterly unworthy of tlie riches with which Providence has blessed our country. The consumption of fuel at Ransko is greater than elsewhere with charcoal furnaces. Thus in Pennsylvania, a ton of metal is obtained from forty-one cwt. of ore, and between twenty- OF IRELAND, 163 five and twenty-seven cwt. of wood charcoal. On the Con- tinent, the ton of metal requires from thirty to thirty-four cwt. of charcoal. So that if tm'f coke alone can be substituted for the wood charcoal, the above estimate may have the cost of the turf removed, and the ton of pig iron should come to about £3 10s. The introduction of the hot blast into charcoal fur- naces has been found attended with the remarkable saving of from one-fourth to one-third of the entire quantity of fuel. With turf charcoal a similar economy might possibly arise, but I shall retain as illustration the cost of production already cal- culated. Although the iron is not prepared from the ore by means of charcoal in any part of England, yet iron bar is manufactured by a mixed process of refining with coke and charcoal, from which a product is obtained of sucli excellent quality as to sell for £14 per ton, and to replace for such purposes as chain cables, nail rods, boiler plates, piston rods, &c., the iron of the north of Europe, which is now, indeed, employed only for con- version into steel for the purposes of cutlery. The quantity of charcoal used in such processes of refining is about four cwt. and a half, per ton of iron. In this method of working also the- charcoal from turf may ultimately be utilized. The consumption of fuel in these processes is so great, and its cost enters so largely into the expense of the manufactm-e, that it becomes important to fix attention upon every mode by which any economy may be effected. The attention of chemists and engineers has been especially directed to this point upon the Continent, and now also in England it is attracting the notice it deserves. During the work of a high iron furnace, the air which is blown into the fire escapes from the top, changed essentially in composition. Its oxygen has, of course, gone to support the combustion of the furnace, but in place of the escape of useless products, as nitrogen and carbonic acid, there is gene- rated a large quantity of combustible gas, which takes fire on escaping, and generates that pale cone of flame by which the high furnace is so well characterized. The gaseous material M 2 1G4 INDUSTRIAL RESOURCES thus passing off was found, on analysis by Bunsen and Ebcl- nicn, to consist of : Nitrogen, from 630 to 60-2 Carbonic oxide, ,, 30*7 ,, 19-7 Carbonic acid, ,, 5*9 ,, 12'8 Hydrogen, ,, 0-4 ,, 7'3 1000 100-0 Now as the quantity of air blown in may be calculated, the quantity of the combustible gases given off may be inferred, and the conclusion finally aiTived at is, that in the high fur- naces a quantity of fuel is carried off under the form of com- bustible gases, which amounts to from 55 to 65 per cent, of the total boating value of the fuel introduced into the furnace, and also, as the gases pass off at an intense heat, they carry away thereby at least 10 per cent, of the heat produced by the com- bustion, so that the quantity of fuel that is really employed in producing the heat by which the iron is smelted, does not amount to more than from 25 to 35 per cent, of that which is actually consumed. This vast loss, of course, more than dou- bles the cost of fuel in the process, and the following means have been devised and successfully employed for utilizing it in other ways. The upper portion of the high furnace, where the charge of ore and fuel does not be yet ignited, is lined with a cylinder of iron, sustained by stays some inches from the brick work. The great body of the gas rushes into this space, where it has not to act against the solid mass of smelting materials. Into this space horizontal flues open on each side, leading to a metal chamber, where they unite, and from which the gas is delivered by nozzles on the floor of the reverberatory furnaces, in which the puddling and reheating is carried on. The chimney of the puddling furnace gives draft sufficient to draw in all the gas. The result practically found is, that the temperature pro- duced by the combustion of the combustible gases of the high furnace is fully sufficient for the puddling and refining of the iron ; and thus tiie fuel (coal, charcoal, or coke) witii which the high furnace is ciiarged, may be made to serve for the en- OF IRELAND. 165 tire conversion of the ore into fine bar iron. Now if we con- sider that it is usually taken in average, that to produce a ton of bars requires ten tons of coals, of which four tons only are used in the high furnace, it is evident that the economy of heat, by the methods now described, may reduce the cost of the bar iron per ton by the price of six tons of coal, and of course the advantage will be proportionally greatest where fuel is dearest. The proportion of hydrogen in the gas evolved, depends on the presence of watery vapour in the air blown into the fui'- nace, and of course varies with it. On this principle is founded another method of economy. I have mentioned, when speaking of the modes of applying anthracite, that when the vapour of water is passed over it at a high temperature, a mixture of hy- drogen and carbonic oxide gases is evolved, by means of which a flaming property is given to that coal : this is the basis of Kymer's and Leighton's patent. This process is em- ployed on the Continent, in order to economize very inferior fuels, such as slaty coal or earthy turf. The plan was origi- nally invented by Ebelmen, but it is now applied in many places. A small furnace is built like an iron furnace, which may be blown either with air or steam. The top may be closed, ex- cept at the times of introducing fuel. From near the top pass lateral flues, which conduct the gaseous products to a chamber, from whence they are led to the furnaces where they are to be burned. Such a furnace is termed a generator. If it be blown vnth air, the products are the same as the gases of the high iron furnace. If it be blown with steam, the products are similar to those given with steam and anthracite. The fol- lowing analyses give the composition of the gases resulting from a generator with very bad coal : BLOWN WITH MIXED BLOWN WITH AIB. AIR AND STEAM, Carbonic acid, . . . 0'5 5-5 Carbonic oxide, . . 33-3 27-2 Hydrogen, .... 28 14-1 Nitrogen, .... 63"4 53-2 1000 1000 166 INDUSTRIAL RESOURCES In the same generator, a fire of turl' blown with air in its usual condition, gave: Carbonic acid, 10-79 Carbonic oxide 21-04 Hydrogen, 9-36 Nitrogen, 58-81 100-00 It is hence evident that even with the worst fuel, by proper arrangements, the purest fire, that of flame, can be obtained ; and thus the local differences of quality of coal or turf almost obliterated by the application of suitable mechanical construc- tions, guided by a correct knowledge of chemical principles. It remains to notice one further mode of economy of fuel that has been adopted with complete success, not merely on the Continent, but also in certain works in Staffordshire. It con- sists in conducting the flues from the puddling furnaces under and round the boilers of the steam engine, so that the water in these last may be boiled, and the steam power for rolling, &c., may be generated by the heat, which should otherwise pass up the chimney and be lost. The results obtained at Abbainvillc may be taken as an ex- ample of the amount of the savings so effected. It is there found that each pound of coal burned in the puddling furnace, evaporates 3-7 pounds of water in the steam boilers. Hence, the economy is at least half of the practical value of the fuel. The steam engine is thirty horse power, and is in almost con- stant activity for driving the cutters, rollers, and punches. The works contain two puddling furnaces. The produce was 1000 tons of bar iron from 487 of coal and 1137 of pig, and this proportion of fuel remained the same, whether the steam engine was driven by the waste heat, or by independent fires. I have noticed these sources of economy, because they, and all similar ameliorations, arc not merely important to be kno^vn in order that the cheapest means of manufacture may be adopted, but that thcjy arc peculiarly of vital interest to us, who labour, as compared with the sister kingdom, under a cer- OF IRELAND. 167 tain disadvantage in regard to fuel. Every thing which dimi- nishes the quantity of fuel, diminishes the amount of this dis- advantage, and hence removes the greatest difficulty felt in the financial success of industry in Ireland. Thus if the Eng- lish manufacturer have an advantage of Is. per ton in the price of coals, and that there be ten tons of coal used to make a ton of iron bars, his advantage is 10s. ; and that 10s. may enable him to send his iron to every part of Ireland, and to destroy our market. But if, by processes in which fuel is economized, the bars be made with five tons of coal, in place often, then his total advantage in fuel becomes but 5s., and this may not be, indeed would not be, sufficient to enable him to keep possession of the Irish market. It is evident also that if one party adopt methods of economy, and the other party do not, the scale is at once and decisively turned in fa- vour of the party who avails himself most rapidly of all im- provements. 168 INDUSTRIAL RESOURCES CHAPTER V.

The numerous other metallic and mineral bodies which are required for the purposes of the arts, must be sought in localities of other and various geological nature ; and hence, in order that a proper rej)rosontation may be given, as well of the actual mineral resources of Ireland, as of the extent to which those resources are capable of i)eiiig developed, it will be ne- OF IRELAND. 169 cessary briefly to enumerate the species of rocks of which the surface of our country is composed, the mode of theii* arrange- ment, and such facts regarding their chemical composition as bear upon technical or agricultural industry. On looking over a map of Ireland, it may be observed that towards the coast the surface is occupied for the most part by mountain ranges, whilst the central portion of the island con- stitutes an almost uniform plane. This diversity of geogra- phical character is accompanied by a difference of geological structure of the most decided character : the mountainous country consisting of the various older or primitive rocks, while the central plain is formed by the limestone, which has been already described as the basis upon which the various tracts of coal formation rest. Almost every district presents in the mineralogical character and arrangement of its rocks, something peculiar in detail, which should be described in a work on the geology of Ireland, and on which many important essays have been published by the Geological Society of Dub- lin; but here such details would be out of place, and I shall only notice the mode of arrangement and constitution of those rocks in a general point of view, and in their principal situa- tions. In the order of formation, which is usually adopted, we may consider the principal rocks found in Ireland, inferior to the carboniferous limestone, to be, granite ; mica-slate ; clay- slate ; old red sandstone ; yellow sandstone. There are also rocks which do not appear limited to a certain position in the above series, but present themselves accompanying sometimes one, sometimes another member of it; of these are quartz rock, various porphyries, and greenstones. In order to render more easily intelligible and definite the fol- lowing brief account of the geological structure of the coimtry, the distribution of the principal classes of rocks has been laid down in the accompanying map. It is not intended to repre- sent every locality of a rock, or every rock that occurs in any locality. It should, on such a scale, in that case become too crowded, and the parts too minute to be of any practical use, but considering the rocks of Ireland to belong to nine principal classes, in their usual order: 170 INDUSTRIAL RESOURCES 1. Granite aud gueiss. 2. Mica-slate. 3. Lower clay-slate. 4. Upper clay-slate. 5. Old red sandstone series. 6. Carboniferous limestone. 7. Coal formations. 8. Newer strata, including sandstone, chalk, and tertiary clays, which collectively occujjy but a small space, and that only round the edge of Antrim. 9. Trap and basaltic rocks. The relations of these classes of rocks to each other, and to the general surface, may be simply represented by the different shadings, as explained upon the map ; the carboniferous lime- stone, which occupies so large an area of the country, being left unshaded for distinction sake. The granite rises from under the other more recently depo- sited formations, at various points, situated mostly along the coast. There are four principal tracts of granite, that of Wicklow, of Gahvay, of Nuwry, and of Donegal. The first is the most extensive ; it commences a few miles from Dublin, on the shore at Dalkey, and stretches in a south-westerly di- rection to near New Ross in Wexford, a distance of sixty-six statute miles. Its greatest breadth is from Kilkea to Sandiford, eighteen miles. The granitic district of Galway commences at the town, and forms the entire of the northern coast of the Bay of Galway. Its northern edge passes by Oughterard to Roundstonc : including the islands, its area is roughly elliptical, with axes of thirty-six miles by twelve. On the eastern coast a granite district, occupying part of the counties of Armagh and Down, constitutes tiie greater part of the hills of Carlingford and the mountains of Alourue, which from opposite sides give so mucli picturesque eft'ect to the Bay of Newry. The extreme range of this granitic district is twenty-eight miles by twelve. The north-western coast of Donegal constitutes the fourth im- portant locality of this rock. Intermixed with vast veins of quartz, it strctciics inland about eighteen miles, and its south- OF IRELAND. 171 eastern edge from Ardara to Glen ranges almost rectilinear for thirty-five miles. In addition to these localities there are numerous others where the rock comes up to the surface, only in small patches. This occurs in Tyrone, in Sligo, Fermanagh, Mayo, and Cavan ; in Kilkenny, and in several parts of Wexford. These smaller masses, however, are not of any industrial interest. The rock granite is of complex constitution, being a mixture of various minerals, of which, however, three are so predominant that they are properly considered its characteristic elements. They are quartz, felspar, and mica. The granite of the vici- nity of Dublin is distinguished for the whiteness of its felspar and the complete absence of hornblende. The granite of the Mourne mountains, on the other hand, contains abundance of hornblende, and the felspar is of a flesh red colour. In many places the texture of the rock is so close that it admits of being worked for artificial purposes, and when polished presents a beautiful appearance, from the varied colours and disposition of its constituent minerals. Other varieties are unfit for this use, from the rapidity with which they are decomposed on ex- posure to the air ; thereby producing the materials of other rocks, as well as the clays of purest quality, and best adapted for the manufacture of earthenware. It is the felspar which is thus altered. This mineral is rich in potash, being composed of Silica, 63*5 Potash, 17-7 Alumina, 16'8 1000 When it is decomposed, the alkali and most of the silica are (•arried off by the drainage water, and furnish to the cidtivated soils of the lower country, those materials so necessary to the growth of their crops of grain. The alumina, with some silica, remains as clay, the uses of which will come again under our notice. The principal lead mines of Ireland are situated in granite. Copper is also found, but not abundantly. It is the usual re- ceptacle of the ores of tin and of the precious metals. The 172 INDUSTRIAL RESOURCES mines which have been found and worked in the granite dis- tricts, will be hereafter fully described. Closely associated with the granite, and usually in contact with it, is mica-slate. This rock is not mucli developed in Leinster ; a narrow fringe of it merely edging the granitic dis- trict of Wicklow and Wexford. In Donegal and Galway it assumes a more important character. Of the former county, by far the greatest part consists of mica-slate, which commencing at the edge of the granite, spreads over the remaining area, and passing into Derry and Tyrone, forms also in these coun- ties the characteristic rock, until it disappears under the sand- stone formation, which, ranging in a circular sweep from Malin-head to Ballyshaimon on the western coast, constitutes its boundary. In Galway a large tract, ranging northward from the granitic district, is formed of mica slate, and this rock occurs extensively also in Mayo, where, although separated by some intervening narrow strips of other rocks, it may be considered as part of the Galway district. Tlie chemical character of mica-slate is by no means defi- nite or uniform ; it graduates by insensible degrees into the rock, which usually lies upon it, the clay-slate, and frequently, by the development in it of felspathic crystals, it passes by slight gradations into that kind of granitic rock, which, still preserving traces of stratification, is called gneiss. The mica- slate has no special metalliferous character, but it is important to remark that the granite is most likely to be rich in metals near its junction with mica-slate. It will be seen hereafter, that the lodes or veins of ore are usually found cutting the line of junction of these rocks. In chemical constitution, mica is very complex, and may yield to the soil, by its decomposition, a greater number of in- gredients than almost any other mineral ; it contains potash, lime, and magnesia, besides silica, alumina, and often soda. It is a material, however, very little susceptible of decompo- sition, as is seen by examining a fragment of weathered gra- nite, where the quartz and mica will be found to remain per- fectly unaltered, whilst the felspar may have totally rotted awav. OF IRELAND. 173 The clay-slate, which usually rests upon the mica-slate, is one of the most important rocks of Ireland, as well from the ai-ea over which it extends, as from the quantity of minerals it in- cludes. The counties of Wexford, Louth, Down, Watei'ford, Cork, and Kerry, are for the most part constituted of this rock, which, however, appears at the surface in various other lo- calities of less extent. Under the name of clay-slate, there have been, until lately, confounded two formations of very different geological character, and occupying different geogra- phical positions. I shall call them by their simplest titles of lower and upper slate, as those names are least liable to mis- apprehension. Of the lower slate there are two great districts ; one north of Dublin, the other south. The northern clay-slate formation commences at Drogheda, and continues along the coast, interrupted only by the granitic protrusion of Carling- ford and Mourne, to near Belfast. Inland, its southern edge ranges almost due east and west until it comes near the Shan- non at Longford. Aline from Belfast to Longford, by Armagh and Clones, marks its remaining boundary. Within this great area, which includes almost entirely the counties of Louth and Down, with parts of Longford, Cavan, Monaghan, and Armagh, the continuity of the clay-slate is interrupted in nu- merous places by the appearance of other rocks upon the sur- face. The only one deserving of remark, is that extending from Moynalty by Kingscourt to Carrrickmacross. It is an insulated district of limestone, with millstone grit and some rocks of the coal formation, and thin veins of coal, of which the character has been mentioned in page 15. The southern districtof lower slate spreads on each side of the Wicklow and Wexford granite, with which it in many places lies in contact; the usually interposed sheet of mica-slate being absent. On the eastern and southern flanks, the clay-slate extends down to the sea-shore and to the River Suir. On the west it is much less developed ; forming the range of hills bounding the granite mountains along the counties of Dublin and Kildare until it reaches the valley of Barrow near Athy. From Wexford, the clay-slate, intersected by the valley of the Suir, crosses into Waterford, of which county it constitutes 174 INDUSTRIAL RESOURCES a large proportion, extending along the coast to near Dungar- van, and westward to where it is overlaid by the sandstone rocks, which form the crests of the Cummeragh and Monavul- lagh mountains. Tlie upper slate, wliich is distinguished from the lower, not merely by its relative position, but by being found to contain imbedded fossils of specific character, of which traces of primi- tive organic life the lower slate appears to be nearly destitute, occupies the greater part of the south-west of Kerry, and the adjoining portions of the county of Cork. Its eastern limit is from Dunmanway to near Macroom, whence, stretching towards Mallow, it constitutes the group of the Boghra mountains, from which the northern edge of the slate district passes due east and west, by Mill-street and Killarney, to tiic Atlantic coast at Doulus Head. The coastward boundary of the upper slate is remai'kable for the bold character of its promontories, which, truly peninsular, project far into the ocean, and are separated by the magnificent bays of Bantry and Kenmare. Some of the most picturesque scenery of Ireland lies within this fiokl, as well as some of the loftiest mountains ; Mangerton and Macgillicuddy's Reeks, Dunloe, and Glengariff, have given to this geographical district, a celebrity from which the oppor- tunities for industrial enterprize which it presents, may pos- sibly derive an extraneous interest. Independent of minor objects, there may bo signalized as belonging to it, one of the most productive copper districts, that of Allihies and Bereha- ven, and in the island of Valentia, the quarries for slates and flags, which afford so large an amount of profit and employment. The peninsula of Dingle consists principally, its western ha'if exclusively, of this upper slate; although it is geographi- cally isolated from the main portion of the rock just noticed, by the interposition of the limestone and of the Munster coal formation, wliich at Oastlemain haven stretches down to the coast. In the other parts of Ireland the upper or Silurian slate is found in but few localities, and there developed but to a small extent. The most remarkable is at Pomcroy in Tyrone, on the edge of the great mica-slate district of Derry, from which OF IRELAND, 175 it is separated by a narrow band of granite. This patch of slate has become of much scientific importance from the study of its peculiar fossils by Captain Portlock, but it does not pos- sess any industrial features that interest us. I have mentioned that the quartz rock, although not itself possessing a stratified structure, is yet usually associated with those formations of mica-slate and the upper and lower clay- slates, and makes its appearance in great beds or projecting veins, frequently capping the mountain ranges, or isolated hills of the slate districts just now described. The greatest development of quartz rock in Ireland, is in Mayo and in Donegal. In Mayo the northern coast from Erris Head to Bealdarig, consists of quartz, which extends inland to near Lake Carramore, and to the south, some of the highest moim- tains, as Nephin, in the interior of the county, are formed of isolated masses of it. Similarly circumstanced are the Bina- bola (twelve Pins) mountains in Connemara, which, situated in the midst of mica-slate, consist of quartz. In the north of Donegal are found vast veins of quartz, from one to three miles broad, more or less interrupted by the ad- jacent granite and mica-slate, and by the protrusions of green- stone and primitive limestone. The largest and most inland of these veins passes fromCullaff Bayin Innishowen, southwest by Buncrana and Ramelton, crossing Lough S willy, and finally tapering off at Firtown near Ardara. Its length is about twenty-three miles. From this to the north-eastern coast, se- veral parallel and similar beds occur, of which the highest mountains in the county are composed, as Muckish, from which such excellent sand for technical uses is obtained, andErrigal. The north island of Arran also is formed by a projecting rock of this materia] . Proceeding south we meet with quartz in connexion with the clay-slate of Wicklow and Wexford. The peninsula of Howth, and the summits of the Sugarloaf Mountains and of Bray Head, which give so much picturesque beauty to the en- trance of Dublin Bay, are composed of quartz. In Wexford a great number of isolated hills are capped with it, and the dis- trict of Forth consists almost exclusively of this material ; 1 76 INDUSTRIAL RESOURCES this is the most southern point of Ireland in which quartz rock is found. Resting on the clay-slate, upper and lower, according to its distribution, and occupying, in the geological series, the inter- val extending from the upper slate to the carboniferous lime- stone, occur a number of rocks, which extend over a very large area of the country, and which, being by no means homo- geneous, either in their mineral character or their chemical composition, it is very difficult to describe without entering into too much detail. These rocks are usually siliceous, the grain varying from the finest sand to large pebbles ; they are hence called sandstones, sandstone conglomerates, &c. The siliceous material is cemented by a paste, usually aluminous, but more or less coloured by iron, whence the trivial distinctive names, as red or yellow, have been derived. In certain localities the upper beds of this formation are less siliceous, and assume a slaty structure, and hence Mr. Griffith, the highest authority on the subject of our local geology, considers, that interposed between the clay-slate and the limestone there may be dis- tinguished three formations, — the old red sandstone, which is lowest, and by far the most largely developed ; the yellow sandstone, resting on the red, and usually accompanying it ; and the carboniferous slate, which has been traced but in one portion of Ireland, in Cork, where it occupies a considera- ble area. The old red sandstone is most extensively developed in the south of Ireland; it forms the greater part of the county of Cork, commencing to the west at the limits of the district of the up- per slate, on which it rests, and extending eastwards until it meets the ocean, to which it forms the boimdary of Cork and Waterford along the greater portion of this coast. Stretch- ing northwards from Cork, almost to the foot of the Wexford granitic ridge, the mountain ranges of Knockmeldon and Com- meragh, and also those of the Galtees, and the Rooley moun- tains, are constituted of this old red sandstone : these moun- tain groups being only separated by the valleys of the Black- water and Suir, into which the limestone of the central plain ramifies. The highest portions of these mountains generally OF IRELAND. 177 shew the clay-slate breaking out from under the red sandstone, and illustrating the geological order of superposition, whilst along their flanks, where they emerge from contact with the limestone, a fringe of the more recent yellow sandstone is ge- nerally to be traced. More to the centre, a great number of isolated patches of this sandstone break through the general flatness of the lime- stone country, especially in Longford and Roscommon; but the greatest development of it, within that district, is in the range of mountains which, under various names of Slieve Boughta, Silvermines, Slieve Bloom, the Arra, Slieve Phelim, &c., occupies a considerable area in the counties of Clare, Lime- rick, and Tipperary, and in the Queen's County, extending north and south from Limerick to near Loughrea, and east- wards to near Mountmellick. The central and highest points of the several portions of these mountains are of clay-slate ; the flanks and general mass are old red sandstone, whilst the edge is fringed with the newer or yellow sandstone, on which the limestone of the sm'rounding level country rests. Through a gorge in this mountain range, at Killaloe, the Shannon rushes, its vast waters being precipitated from the level expanse of Lough Derg down the rapids of Doonas and Castletroy to- wards Limerick. In the Arra mountains on the eastern side of the lake, are the well known slate quarries of Killaloe, which, together with numerous localities of mineral and metallic sub- stances in this district, will be hereafter noticed. Between the mica-slate, clay-slate, and quartz rocks, which form the west of Mayo, and the limestone, is interposed a large tract of old red and yellow sandstone, which from the north coast at Killala, skirts by Loughs Conn and Cullin, and reaches the Atlantic again at Westport. In Tyrone another large field of old red sandstone apjiears. It extends from near Cookstown to the shores of Lough Erne, about twenty miles, and its breadth is about six miles, marked by Omagh and Bal- lygawley, which are just on its boundary. Scattered around, and some miles from it, are several smaller patches of the same rock, and of the yellow sandstone, which, however, could not be described without entering too much into detail. This sand* N 178 INDUSTRIAL RESOURCES stone district may be considered as interposed between the great mica-slate formation of Derry and Donegal, and the more southern limestone country, of which the arms stretch up by Monaghan and Clogher to Coal Island and the basin of Lough Neagh. The only locality in which the third member of this geologi- cal series, the carboniferous slate, is found developed, is on the south-eastern coast of Cork. There it rests on the yellow and red sandstone, and forms a band, of which the usual breadth, as from near Bandon to the Old Head of Kinsale, is about seven miles, and the greatest length, from Dunmanus Bay to the mouth of Cork harbour, about thirty-four miles. In the promontories of Dunmanus and Skibbereen, the central mountain ridges are of the old red sandstone, on which, at each side near the coast, rests the carboniferous slate : the newer rock, as in most instances, occupying the troughs or more level area between the bolder elevations of those lower in geo- logical order. Several valuable mines of copper, lead, and manganese are situated in this rock. Already in the commencement of this work, the general distribution of the limestone rock, and also of the strata of the coal formation which rest upon it, has been noticed ; and at- tention was directed to the great development of the millstone grit, or sandstone of the coal formation, in Leitrini and Ros- common, the circumstances of which, particulai-ly the marine cliaracter of its fossils, induce Jlr. Grifltith to consider it a dis- tinct formation, lying between the carboniferous limestone and the true coal strata. The Connaught coal field would, there- fore, require, in a purely geological sense, to be distinguished fi-om the other coal districts which are not connected with the millstone grit formation, but are more recent and superior to it, in order ofsuperposition. These considerations are, however, of interest only in philosophical geology; they are not con- cerned in the practical description of our coal districts given in a preceding chapter, and hence do not require further notice. The limestone strata yield for industrial purposes a great va- ri(!ty of building stones and marbles. Tiie sandstones and con- glomerates are used for building, and for millstones. The OF IRELAND. 179 most important localities for such uses will be hereafter enu- merated. The rocks superior in geological order to the coal formation, are found in Ireland to occupy but a very limited area, being confined almost exclusively to the north-eastern corner of the island, forming the county of Antrim, with some portions of the contiguous counties of Derry and Armagh. In an ascending order the rocks met with in this district are, magnesian lime- stone, new red sandstone, black shale, lias limestone, green- sand, and chalk. These rocks present themselves, however, but on the edges of the district, as the whole is covered with a thick mass of tabular trap (basalt), from which the most characteristic features of the country are derived. Viewed from a distance it appears as a high table land rising from the flat country, or from the sea. Its outline is marked by lofty precipices and barren cliffs, especially along the eastern coast, where masses of black trap from 200 to 300 feet in thickness, often columnar, surmoimting precipices of chalk, of dazzling brightness, of 60 or 100 feet high, present a series of objects, which, for beauty of conti'ast and pictm-esque effect, are sel- dom rivalled. The vast flood of trap and basaltic rocks which overspread this part of Ireland, has, in many cases, so altered the mineral character of the underlying rocks as to render them very un- like the rocks which occupy the same geological position in England. Still they are completely identified by the fossil contents, and in general distribution are as follows. The magnesian limestone is found but at Hollywood, on the southern side of Belfast Lough. It is a true dolomite, and has been exported to Glasgow to make sulphate of magnesia. In composition it is the same as the dolomites found in various other places in Ireland, of which the more imjjortant shall be noticed hereafter. The new red sandstone, which in England covers so large an area, and is of so much industrial importance, from its being the depository of rock salt and gypsum, is with us but of very limited extent, and is totally destitute of the former valuable mineral. The sandstone, which is usually brownish red, con- n2 180 INDUSTRIAL RESOURCES sisting of grains of quartz cemented by a paste, which, though usually argillaceous, is sometimes calcareous, contains much mica, and is often striped with various colours, from decompo- sition of its ferruginous contents. This sandstone comes to the surface at various points along the edges of the basaltic field ; but its principal development is in the valley of the Lagan, which it constitutes from above Moira by Lisburn to Belfast. Resting on the sandstone are the gypseous marls, which, as a source of plaster of Paris, I shall again notice. To these succeed shales and limestones, which are of the forma- tion termed lias, in England, and finally, the chalk, which pre- sents all varieties of hardness, from its usually soft condition, to that of a hard and granular, but beautifully white marble. Some isolated patches of new red sandstone are found rest- ing on the limestone of the more central districts, and also on the coal district of Tyrone. The coal strata of Monaghan, described pp. 15 and 173, are surmounted by the new red sand- stone, and by marls, important for a large deposit of gypsxmi, to which I shall again refer. Strata of the tertiary epoch are found in Ireland, only at the southern shore of Lough Neagh, where the clays containing wood coal occur. These have been sufficiently noticed in page 31 as a source of fuel. Finally, the igneous rocks, which, according to differences in minute mineral character and structure, receive the various names of trap, basalt, greenstone, &c., cover over the entire table laud of Antrim, These rocks are remarkable for the complexity of their chemical composition and the varieties of imbedded minerals which they contain. They are hence de- composed with great rapidity, and produce ochres and clays of various and beautiful colours, of which beds of great extent occur in Antrim. The soil formed round the edges of this dis- trict, by the mixture of the decomposing trap and subjacent rocks, is one of the most naturally fertile that is found in Ire- land. Such are the general characters of the geological structure of Ireland. The various groups of rocks differ remarkably in OF IRELAND. 181 their chemical composition, and consequently are applicable to very diversified uses. Their composition, and also the cir- cumstances under which they have been found, and the agen- cies to which they have been subjected since their formation, influence materially their mineral contents, and it will be found that the distribution of the several kinds of mineral substances of use in the arts, coincides very closely with the geological arrangement of the rocks. It will be more convenient, how- ever, for the present, to abandbn all geological considerations, and merely consider how the several mineral substances of leading interest are circumstanced in Ireland. 1st. Of the Copper Mines. The ores of this valuable metal are found distributed through- out the clay-slate districts in a great number of localities, more or less abundantly. In many places the indications are so trifling g,s not to offer any inducement to enterprize ; in others, so abundant as to have given origin to numerous extensive and prosperous mining establishments. The mines of copper at present in practical work, may be conveniently described as forming three great groups, all on the sea side. The first, in the county Wicklow, occupying the valley of the Ovoca. The second is in the county of Waterford, occupying the dis- trict of Knockmahon, and the third, occupying the south- western angle of the island, is situated in the southern por- tions of Cork and in Kerry. Each of these districts deserves special examination. A number of smaller mines which are scattered through other parts of Ireland may be noticed more brieflj' afterwards. Before proceeding to that subject it will be found convenient to remark, that the copper ores most usually found, and which alone become practically of importance, are three in number. 1st. The carbonate of copper, of which there are two kinds, green and blue. The green, or malachite, is not unusual in mines, but occurs only in small quantity. It is very rich in metal and very easily worked. It consists of carbonic acid, water, and oxide of copper in the following proportions. 182 INDUSTRIAL RESOURCES Oxide of copper, 72-07 Carbonic acid, 19-82 Water, 8-11 100-00 It hence yields 57 '7 per cent, of copper. This mineral, when pure, possesses a beautiful structure and colour, which render it very valuable for ornamental uses. The blue carbonate is still rarer tliantho green. It is termed azurite. Its composition is, Carbonic acid, 25-43 Oxide of copper, 69-36 Water, 5-21 100-00 and it yields 55-5 per cent, of copper. 2nd. The subsulphuret of copper, grey copper ore. This ore is sometimes found very abundantly, and is the most valuable of all the ores of copper. More commonly, however, it is only found in small pieces mixed with the ordinary ore. It consists of Sulphur, 20 Copper, 80 100 3rd. The ordinary, or yellow copper ore, copper pyrites. Tills mineral, knowu by its brilliant golden yellow colour, is a double sulphurot of iron and copper, and contains, when pure, Sulphur, 34-78 Copper, 34-78 Iron, 30-44 100-00 In some of the foreign mines the grey sulphuret is the pre- dominant mineral, but in all the Irish, indeed also in all the English mines, it is the copper pyrites which forms the material produce; the other ores being but casually found and in very triflingjiuautity. OF lUKLAND. 183 The copper pyrites is associated almost universally with iron pyrites, the bi-sulphuret of iron, the peculiar uses of which shall be hereafter specially noticed. The effect of this mixture is to reduce the per centage of copper, which is further de- pressed by the impossibility of separating, even by the most per- fect machinery, all the adherent rock and veinstone from the ore. Hence copper ore, which contains 12 or 15 per cent, of copper, as sent to market, is considered very rich. The average produce of the copper mines of Cornwall does not exceed 7 per cent. The ore is of course valued according to the quantity of copper which it contains, subject to certain deductions, which it is not here necessary to explain. Metallic ores are very rarely found disseminated through the general substance of the containing rock, indeed where they are so, they are seldom worth the trouble of extracting. A rock of which the mechanical and chemical structure is uniform, very seldom contains any important quantity of copper or other ores. These occur where a rock has been violently acted upon subsequent to its formation ; its strata dislocated and its substance split up by the forcible entry of other kinds of rocks, which, penetrating its mass, form veins, ramifying in various directions, and traceable sometimes for hundreds of miles. It is in those veins, Avhere many different materials are brought into contact, and that the forces of heat and electricity probably awakening the chemical affinities of the elements of the rocks, induce their action on one another, that metallic deposits occur : the vein rock, which is very commonly quartz or sulphate of barytes, or fluor spar, having within it or at its side a vein of ore more or less rich, but unfortunately very capricious in its distribution and in its magnitude. Usually, however, the more violent the action on the containing rocks appears to have been, the richer are its metallic contents. If several veins meet, cross, and shatter one another, the ore is likely to occur in masses or bunches at this point, and where the structure of therock be- comes regular, almost universally the metallic veins disappear. The substance of the vein rock is often termed the gangue or matrix of the ore, or the veinstone. The separation of the ore from it, by picking, pounding, and washing, forms an extensive 184 INDUSTRIAL RESOURCES series of operations, for the description of which the standard works on mining and metallurgy may be consulted. Such being the circumstances under which metallic ores are usually found, I shall pass to the description of the districts of the copper mines of Ireland. 1st. Of the Wlcklow District The principal features of this district have been so accurately described by Mr. Weaver, who was for many years principal conductor of the mines, that I shall do little more than abridge his description, and add thereto such facts as I have been able to collect illustrative of their subsequent progress and their present condition. The metalliferous clay-slate district occupies but a small space, being very narrow in breadth, and not more than ten miles long, from Croghan-Kinshela on the south, towards West Acton on the north. Metallic substances are diffused throughout the entire space, in slight layers, in cotemporaneous veins, and in massy beds, which last are principally composed of copper pyrites and iron pyrites. The line of the excavations of the works in Connoree and Tigroney extended in 1819 upwards of 1000 fathoms. At various depths in the mass of the clay-slate occur beds of what is technically termed soft ground, which consists of decomposed slate of various tints, abounding in particles of jiyrites of iron, and sometimes copper and arsenic, and usually accom- panied by a considerable body of greyish or yellowish-white clay. When brought to the surface and exposed to the action of the air, these bodies rapidly decompose, and absorbing oxygen form alum, sulphate of iron, and sulphate of copper. A similar decomposition takes place under ground, and hence the drainage water of the district contains a very sensible quan- tity of copper, which has been, and indeed is, economized by conveying the water as well from the lower as from the upper mines into tanks, where the muddy particles are allowed to subside. The clean water is then run into pits containing scrap iron, which causes the precipitation of the copper and dissolves in its place. An idea of the ijuantity of copper thus saved from waste, may be formed from the fact, that during Mr. Weaver's management there were 442^ tons of impure preci- OF IRELAND. 185 pitated copper sold, the value of which was £12 12s. per ton. The quantity of iron consumed was 429 tons, 14 cwt. Each bed of soft ground contains one or more layers of cop- per pyrites, or mere iron pyrites, varying in thickness, and sometimes acquiring a breadth of several fathoms. Five of such beds are met with, one in Connoree, two in the old or upper mine of Cronebane, one in the new or lower mine, and one in Tigroney. That in Connoree contains abed of ore about four feet thick, consisting of a fine-grained intermixture of galena (sulphuret of lead), grey ore (sulphuret of antimony), and blende (sulphuret of zinc), with pyrites of copper, iron, and arsenic. A similar compound occurs in the second bed of the upper mine of Cronebane. The more southern bed contains much iron pyrites, and has yielded, at different periods, some thousand tons of grey copper ore, which, in the greater depth of the mine, passes into copper pyrites. The third bed, in Cronebane, situated on the western side of the hill, has proved the most valuable, the greater part of its width being occupied by copper ore, which in the upper part consisted principally of grey ore, but at greater depths passed into copper pyrites with iron pyrites. The bed of solid ore has varied from one to three fathoms in breadth ; no quartz or spar of any kind attends these beds. The more productive parts of the bed have, in several instances, yielded from ten to fifteen tons of merchantable ore per cubic fathom, the average produce of which has varied from five to seven per cent, of copper. The bed in Tigroney had yielded only iron pyrites when Mr. Weaver wrote. Beds of iron pyrites, from a few feet to some fathoms in thickness, have appeared in the firm and flinty slate, as in the deep levels of Tigroney and Cronebane. In the flinty slate are found also several cotemporaneous veins of quartz, having rich copper pyrites, accompanied sometimes by azure copper ore, and whose average produce is from 10 to 12 per cent, of cop- per. These veins range with the slate, ramifying, and where they coalesce, forming a body sometimes twelve feet wide, with four or five feet of solid ox"e, but they seldom continue produc- tive for more than thirty fathoms in length. Small veins of this description are very numerous. The mines of Connoree, Cronebane, and Tigroney, so often 186 INDUSTRIAL RESOURCES mentioned above, are situated on the north bank of the Ovoca River. The structure and circumstances of the southern side, on which are the mines of Ballymurtagh and Ballygahan, are precisely similar. It is, therefore, unnecessai-y to enter on a description, which should be mainly a repetition of what has been already said. The quantity and value of the ore raised in th s district, at various periods, may be inferred from the following numbers. In the twelve years ending 1799, the mines of Cronebane yielded 7533 tons of ore, containing 9 per cent, of copper. In the twelve years ending 1811, the produce was 1934§ tons, containing 5^ per cent, of copper. After this period, owing to many conspiring causes, very little ore was raised for many years. Mr. Griffith states, that in 1826 the copper ore raised in Cronebane sold in Swansea for £12,354 14s., and the ore raised at Ballymurtagh sold for £3373. The latter was worked by the Hibernian jMining Company, on a single metallic bed, con- taining copper pyrites with some blende. The lode (vein) at eighty fathoms depth yielded per fathom of driving four tons of dressed ore, of 5i per cent, produce. The ore, he calculates, cost the Company, when finished, £7 per ton, and certainly left little, if any, profit. The following tables, illustrative of the actual condition of the mines of this district, have been extracted from the notes of sales at Swansea, and from notices published in the Mining Jommal. The quantities of copper ore from each mine, which was sold at Swansea, and its value, was in 1836 : MINE. TONS. VALUE.

The quantity of ore sold at Swansea has, however, fallen off very much, as is shewn* by the above returns, owing to the copper being now exten- sively smelted in the neighbourhood of Liverpool, and also to the poorer ores of the Wicklow district being extensively ex- ported to various localities of chemical manufacture, where the sulphur, as well as the copper which they contain, is econo- mized. The true produce of this district at present may be judged by the following table of the ores raised and sold from the Ballymurtagh mine, worked by the Wicklow Copper Mining Company, for which I am indebted to the kindness of Mr. Wright. 188 INDUSTRIAL RESOURCES " BALLYMURTAGH, CO.

It is here seen that the industry of this region has acquired a vast development within the last ten years. This arose from another branch of mining industry coming into play ; the trade in iron pyrites as a source of sulphur. In tlie Wicklow district the copper ore is associated with such vast quantities of iron pyrites, that in order to raise it, it is necessary to quarry the latter to a large amount, which very much enhanced the cost. But when there arose an outlet for the bisulphuret of iron, the mining for the copper ore became much more remunerative, and hence the vast quantities which have been sent to market since that period. It has been seen that by the operations of the Ballymurtagh mine, about £12,000 is annually distributed in wages to about 700 persons. Including the other mines, the total number of persons deriving employment from the mineral industry of the Ovoca district may be considered as brought up to about two thousand. 2nd. Of the Waterford District The geological character of the slate district of Waterford has been already noticed. That part of it which includes tlu; Knockmahon mines, is situated on Iho sea coast, close to tiie vilhi'n' ol'lJonuiahon, and extends OF IRELAND. 189 from the Bay of Dimgarvan on the west, to the Bay of Tramore on the east. It has been long known for its mineral treasures ; many of the metalliferous veins having been worked by the ancient inhabitants. One almost insulated promontory is per- forated like a rabbit burrow, and is known as the Dane's Island; the peasantry attributing these ancient mines, like all other relics of remote civilization, to that enterprizing people. In the abandoned workings antique tools have been found, stone hammers and chisels, and wooden shovels. These work- ings were easily carried on, as the metalliferous veins presented themselves at the face of the cliffs on the sea shore, and they were abandoned as soon as, by the accumulation of water, or an exhaustion of the richer ores, they became difficult to ma- nage. Within a range of three miles, taking Bonmahon as a centre, a great number of lodes of lead and copper are distinguishable in the cliffs, some of considerable Avidth, but others compara- tively small. The direction of the principal lodes is about 20° south of east, but others vary considerably from this. The principal lodes dip towards the north. The most productive at present in course of working, occur in the clay-slate, although they sometimes penetrate through the strata of other rocks, as hornstone, which are found within the slate. In this hornstone Mr. Holdsworth has remarked the presence of several ores of cobalt, but not in quantity. The lead veins, which con- tained galena (sulphuret of lead), and calc spar, are not worked. The cop2)er lodes consist of quartz, and produce na- tive copper, sulphuret of copper, grey copper ore, and black oxide of copper. Sulphuret of zinc, carbonate of iron, and sul- phate of barytes occur occasionally, and also argentiferous sulphuret of lead. It has been seen already that there is found, in addition to the ordinary clay-slate of this district (Cambrian slate), a small deposit of the superior slate containing fossil remains (silu- rian), which is found so much developed further south and west. It is, however, here not of practical importance. In the following letter from Captain Petherick, the manager of these mines, additional circumstances of their structure, 190 INDUSTRIAL RESOURCES as well as their actual extent and workings, are well de- scribed : " My dear Sir, — The rock formation in which the metalli- ferous veins of this district occur is principally clay-slate of a light blue colour, and immediately in contact with the produc- tive part of the vein it is generally in a softened or partially decomposed state. " The veins are composed of hard compact quartz, inter- mixed occasionally, particularly where they prove unproduc- tive, with angular fragments of clay-slate ; the quartz is the matrix of the ore. " Our principal vein varies in width from six inches to up- wards of thirty feet, but its average size is probably from ten to twelve feet : it is, in fact, an unusually large lode ; nume- rous smaller veins also occur on each side of it, some of which have been worked with partial success, but as far as they have yet been explored, they have vmiformly become small and un- productive in depth, and at present our operations, with a few trifling exceptions, are exclusively confined to the larger vein. " The mining ground leased to the Mining Company, ex- tends about four miles along the coast, and nearly three miles inland. " Grey snlphuret of copper, native copper, and the red oxide of copper, occur occasionally in the shallow workings, but in comparatively small quantities ; the most abundant, and therefore the most remunerative ore, is the yellow pyrites, and in the deeper levels no other kind of ore is met with. "The average per centage of the produce of these mines is 9» to 10 per cent. "The greatest depth we have yet worked is about 800 feet from the surface ; and the greatest length of our underground workings is rather more than an English mile, in a direct line. " The number of persons in constant employment in these mines is about 1200; and of that number 140 are females em- ployed in cleaning the ores. No females are ever permitted to go underground. OF IRELAND. 191 " It is a remarkable characteristic of this district, at least I have never observed it elsewhere, that a part of the vein is composed of a conglomerate of pepples of quartz and copper, in an undurated clay-jjaste. Sometimes the fragments of quartz are angular, but more frequently they occur in a rounded state ; and occasionally the copper is disseminated in small particles throughout the paste. When I have an op- portunity I will take the liberty of sending you a few speci- mens of the conglomerate, which I am sure will be interesting to you. ' ' Your's, very faithfully, "John Petherick." The mines of this district, at present working, consist of four groups, which are held by the IMining Company of Ireland from different proprietors. They are, Knockmahon, Kilduane, Bonmahon, and Balinasisla. In the returns of ores sold, these divisions are not distinguished, and hence the following table gives only the aggregate produce, and the average value of the entire : YEAR. TONS.

This extension has been accompanied by some very re- markable circumstances, to which I shall hereafter direct at- tention. The ores are dressed at Knockmahon by very perfect ma- chinery, which is set in motion by overshot wheels, of which one is forty feet diameter and four feet wide : for which there is an ample supply of water. In these operations, as well as in mining, employment is given altogether to an average of 1200 persons, whose earnings fluctuate with the produce of the mine. The sum paid by the Mining Company for labour, in this dis- trict, is not less than £2300 per month. 192 INDUSTRIAL RESOURCES 3rd. Of the soutli-western District The space occupied by the clay-slate i'onuation in the counties of Cork and Kerry, has been found rich in mineral indications ; but in many cases, where ti'ials have been made, often at very great expense, the result has been unpromising. Of these failures many may be traced to the incompetency or imprudence of the undertakers, but others to the peculiarities in the nature of the ground, which could not have been foreseen. Some mines have been remarkably productive, of which the Allihies mine, belonging to Mr. Puxley, and conducted by Captain Read, is an excellent example. Although indications of metalliferous veins have been noticed in all parts of this vast district, it is especially towards its edge, round the sea coast, where it is more or less in contact with, or in the vicinity of the older slate, or of the old red sandstone, that the more important deposits are found, and hence proceeding from east to west we may trace the series of mining localities of greater or less importance from Skib- bcreen in Cork, to Kenmare and Killarney. Between Skibbereen and Skull, at the village of Ballydehob, a vein of copper ore was found of considerable extent upon the surface, and of good produce. This mine was worked with activity for about four years ; it gave employment to about 200 persons, and many thousand tons of ore were shipped to Swansea. It was foimd, however, that according as the work- ings descended below the surface the lodes became impove- rished, and it was ultimately abandoned as unprofitable. It is stated that parties are about to make new trials of this mine. About ten miles west of Skibbereen, on the property of Lord Audley, are metalliferous veins in great number, on which mines have been opened, known as the Audley mines, and which, like the Arigna Iron Company, have been the means of bringing into disrepute Irish industrial enterprises, through the fault of jobbing speculators in London. The district of these mines comprises about 5500 acres. The principal lodes are three in number, not far asunder. The first consists of quartz, with bright yellow copper and iron pyrites, which has lu-'cn found to contain usually about 8 per cent, of copper. In the second, which has been but littli' worked upon, particles of OF IRELAND. 193 carbonate of copper (malachite), with nodules of grey sulphu- ret of copper, are disseminated through the clay-slate rock. The third, the Cappagh lode, is that which was principally worked upon. It contained copper pyrites and grey copper ore. The produce was so rich, as to give 55 to 65 per cent, of copper, but these indications, so favourable near the surface, diminished as the works went down, and the mines were, after some time, abandoned. It being considered that their failure in the hands of Mr. Hall, their first undertaker, arose from want of capital, the Mining Company of Ireland took them in hands, and expended £12,000 in fully examining their value. The shaft on Cappagh was sunk to 120 fathoms, and works were extended in levels 200 fathoms. The indications of the veins on the surface shewed that they should intersect at that depth, and it was hoped that, as very frequently occurs in mines, a great deposit of metallic ore should be found at the junction. On the contrary, it was discovered, that after their junction they became unproductive, and the works were aban- doned. At Horse Island, similarly, the ore near the surface yielded in some cases 55 per cent, of copper, and 230 tons which were sold at Swansea, realized £2800, but on the shaft being sunk to forty fathoms, the lode, like the others, became impoverished, and the IMining Company surrendered their lease to the proprietor of the soil. A company was afterwards formed in London, which purchased at an enormous sum, up- wards of £100,000, the right of working these abandoned mines, and their affairs have been in litigation ever since. The whole produce sold by this Company (the West Cork Mining Company) appears, by the Swansea returns, to have been 173 tons of ore, which realized £1601 12s. A comjiany formed as that was could not come to good in any way, and it is to be hoped, that the future operations in this field may be executed by persons more deserving of success, and more competent to secure it. South of the district of the Audley mines, on the shores of Roaring-water Bay, are situated the mines of Roaring-water, of Cosheen, and of Skull. At Roaring-water the lode is fri- 19-i INDl'STRIAL RESOURCES able quartz and gossan, with bunches of black and grey cop- per ore. As the workings descend, this passes into rich yellow copper pyrites, which is described as free from iron pyrites. This is a new mine. I do not know that it has yet sent any ore to market. I trust that the indications of rich produce shewn upon the surface, may not be found to vanish further down. Of the mines of Cosheen and Skull, the former is situated on the shore, the latter on the island of that name. The Cosheen mine was commenced in 1839 by Messrs. Connell and M 'Mullen of Cork. It is advantageously situated on the side of a hill at Skull harbour. A deep adit level has been driven in, just above high water mark, for about 250 fathoms, in the course of the principal lode. This adit drains the mine, and by it the ore is extracted ou a railway. The adit is now being driven farther south to cut some parallel lodes which had been suiierficially explored. The arrangements for working this mine have been made on an extensive scale, under the direc- tion of Mr. Thomas. The number of hands employed is about 130, and I trust, that its proprietors will continue to receive the benefit they deserve, for an enterprize which has brought comfort to a hundred families that had previously no employ- ment. The ore from these mines, which are but a short time open, was, as given in the Swansea returns : In 1840, Cosheen, 126 tons, value, . £1164 2 In 1843, Cosheen, 360 „ ,, . 2605 15 Skull, 84 ,, „ . 134 8 The most important mine in this district is that conducted by Captain Reid, near Ballydonegan Bay, on the west side of the promontory of Here. The existence of mineral deposits in this locality was first recognized by Colonel Hall, and pointed out by him to the projjrictor, Mr. Puxley. Tlic following par- ticulars as to its actual state were communicated to me by its very skilful manager : This mine was commenced about thirty-three years ago, OK IRELAND. 195 under the name of the Allihies mine, but as the workings are now removed from the land of Allihies, the name of the Bere- haven mine has been adopted for it. In the space of three or four miles are several veins, most of which run east and west, and dip to the north. Some of these were found on trial un- productive, and were abandoned ; but two veins, one called the Mountain, being situated 450 feet above the level of the sea, on a large east and west lode, the other, the Camlnche vein, which rims north-east, have furnished the principal workings. In the JNIountain, a groat quantity of copper ore has been raised ; there is still obtained about 200 tons per month, of about 10 per cent, produce. The principal working is about 760 feet in length, and 852 feet in depth. The lode is sixty feet wide in one place, but branches and narrows in other places to three or four feet. It consists of quartz and cojjper pyrites. It is all blasted with gunpowder. The deepest levels had been hitherto rather unproductive, but just now, ore of excellent promise has been raised from them. The Caminche vein is worked for about 570 feet in length and 912 in depth. The engine shaft sinks sixty feet more. The~vein runs north-east and dips south-east. It has been very productive ; the ore is cleaner than in the Mountain vein; the breadth of the lode is from one to twelve feet. There are employed in these mines about 1000 persons, as follows : Miners, 400 Smiths and joiners, 30 Helpers, 25 Laboui'ers, 245 Boys 170 Girls, 130 Mr. John Reid, who is engaged in this mine under the di- rection of his father, kindly furnished me mth the following analysis of the usual quality of ore : he found it composed of o2 196 INDUSTRIAL RESOURCES Copper, 10-2 Iron 10-8 Sulphur, 14-8 Quartz, 63*9 Loss, 0-3 100-0 A short distance from these copper veins, is a vein of lead, which was worked some years ago, and some ore raised, but as it did not promise very well, the workings were not pro- ceeded with. Owing to the conformation of the surrounding country, there is no command of water power at Allihies, and all the machi- nery for crushing and dressing the ore is driven by steam en- gines, of which there are five at work. The ore raised in this mine is about the same quality as at Knockmahon, varying from 10 to 13 per cent, of copper. In the return made to the Railway Commissioners in 1837, the average annual produce is given at from 6000 to 7000 tons, valued at £9 per ton. I find by the returns of sales at Swan- sea, that the produce was in YEAR. TONS.

At Holyhill, near Bantry, workings have been executed on a vein of copper ore, but are not now in operation. At Ardtully, near Kenmare, is a copper mine worked by the Kenmare Mining Association. The produce is the ordinary copper pyrites of moderate richness. The principal shaft has been sunk about twenty fathoms, and the levels extend about sixty. The lode of (juartz and calc spar is about five feet wide: it lies at the junction of the clay-slate and limestone. OF IRELAND. 197 In 1843, there were sold at Swansea from this mine thirty-one tons of ore, wliich brought £275 18s. The workings of it are as yet but in their infancy. There are about 100 persons em- ployed on this and the lead mines belonging to the same com- pany and situated close by. The Lakes of Killarney mark the line of junction of the un- derlying slate and sandstone rock, with the limestone which fi*inges the Munster coal field. Along this line, metallic in- dications have been found in several points, on two of which mines were opened, which, although not now wrought, deserve some notice from the extent to which they were at one time worked, and the peculiar circumstances under which they were abandoned. These localities are Mucruss and Ross Island. The Mucruss mine was situated near the head of the great lake, by which, and the River Laune, a complete water com- munication was opened to the sea at Castlemaine. The lode was five feet wide, and was worked at the depth of thirty-six fathoms on the front shaft, and about twenty by another, sunk some distance to the east. The ore was copper pyrites mixed with much iron pyrites. This mine was worked with great profit from the years 1749 to 1754, but difficulties arising from the circumstances of the European war caused its abandon- ment. A curious fact in the history of this mine deserves at- tention. There was found in great profusion a mineral of a granulated metallic appearance, as hard as stone; its colour on the surface dark blue, tending to a beautiful pink. It was not copper ore ; it was thrown away as rubbish : nobody knew what it was, except one workman, who recognized it to be cobalt ore (arseniuret of cobalt), a mineral of great value, from Avhich the beautiful blue glass and smalt blue is made. This man managed to get away upwards of twenty tons of it as rubbish. Long afterwards a more candid miner, who visited the works and saw some specimens of it, told the proprietor its value ; but the deposit of it had been worked out in order to explore for copper ; the produce had been thrown away as useless, and it only remained for the mine owner to ruminate 198 INDUSTRIAL RESOURCES on the fortune he might have made, if he had possessed a pro- per knowledge of his business. Ross Island, in the great Lake at Killarney, consists of limestone ; the metallic lode which passes through it is parallel to that of ]Mucruss. It dips under the lake at an angle of 30°, which circumstance ultimately led to the abandonment of the mine, for the ore being disseminated through a large quantity of rock, the excavations were necessarily large, and the pursuit of the richer veins was pushed so near the surface, that the water of the lake broke in in such profusion as to render the effective drainage impracticable. The quantity of rock brought up with the ore was another source of loss, as the cost of dress- ing was thereby rendered very heavy. The quantity of ore raised whilst this mine was at work averaged 200 tons per month. It was, however, very rich. The poorest sold for £14 per ton, and the richest for £40 : the average being about £20. The total value of the ore raised in four years, and sold at Swansea, was £80,000. The number of hands employed was about 500. In order to drain these mines a steam engine was put up, and that an idea may be formed of how carelessly matters were ma- naged at that time, it may be here mentioned, that whilst every square mile of the vicinity furnished abundance of turf for the trouble of cutting it, the steam engine was supplied with coals from England at two guineas a ton. The range of mountains which occupies the north of Tip- perary, and forms the gorge of Killaloe, has been found to contain several veins of lead and copper. Of these some are now worked : others have been abandoned after trials, which were not finally satisfactory. I shall notice these mines but briefly. These mountains consist of clay-slate, fringed in most places by the old red and by the yellow sandstone, but in others coming directly into contact with the edge of the lime- stone of the plain. At such a junction is situated Silvermines, deriving its name from old and profitable workings which are now exhausted. A split between the limestone and clay-slate of several fathoms wide at top, and twenty-five fathoms deep. OF IRELAND. 199 was occupied by soft decomposing clay, with lumps of sand and limestone, cemented by various metallic substances, iron ochre and pyrites, sulphuret and carbonate of lead, sulphuret and carbonate of copper, and sulphuret of zinc. Lead was ex- tracted from this mass, and the lead so obtained being un- usually rich in silver, gave to the vicinity the name it at pre- sent bears. In the clay-slate tract, south of Silvermines, are several me- talliferous veins. In Knockeenroe a powerful vein, consisting of quartz and iron pyrites, with some galena, ranges nearly east and west, and may be traced for a considerable distance, until it sinks under the sandstone which caps the hill. In the latter part of its course it contains copper pyrites. This vein has been examined by Mr. Taylor, who, after some trials, gave it up, and then the Mining Company of Ireland, at the time when the monopoly of the sulphur trade had led to an active demand for iron pyrites, essayed to work through the great mass of sulphur oi-e, hoping that its sale would enable them to finally ascertain the prospects of copper ore in its interior. It was found, however, that the inland position of the mines, and the refractory nature of the rock, rendered the iron py- rites raised too costly for sale in the English market, and hence the Company was obliged to abandon the investigation without having penetrated through the vast body of sulphur ore which forms the vein. Higher on the mountain, above the junction of the sandstone and clay-slate, are three veins of smaller di- mensions, they consist of quartz with sulphate of barytes, and the sulphurets of lead, iron, and zinc. In the valley of the Newport River are situated the mines of Lackamore. The lode consists of carbonate of lime and iron, bearing rich copper ore in bunches. This mine has been long known and worked. In 1812, when Mr. Weaver wrote, the workings had extended 120 fathoms in length, at a depth of 30 fathoms. After that time they were abandoned, but have been recently brought into activity. There are now about 200 persons employed, and there were sold at Swansea from this mine, in 1840, 111 tons of ore, which produced £1153 7s. > and in 1843, 260 tons of ore, which realized <£ 238(3 IBs. 200 INDUSTRIAL RESOURCES In the slate district north of Dublin there have been found veins containing ores of copper, which, however, were small and irregular, and have not been found in any case, as yet, pro- fitable to work. At Lough Shinny, near Rush, three veins oc- cur, on which extensive workings have been made, and a good deal of ore raised from time to 'time, but the operations do not appear to be continuously carried on. On the coast at Sal- tcrstown, in Louth, veins of lead and copper appear, which were tried and abandoned by the Hibernian Mining Company. At Brownstown, in IMeath, a vein of copper pyrites has been found traversing the limestone. Some superficial workings had been made upon this vein, but they have not been since prosecuted. In Tyrone, some miles from Dungannon, a number of masses of grey sulphuret of copper have been found, some of consider- able size ; they were imbedded in a soft vein in the conglome- rate, resting on the old red sandstone, very near the junction of the two rocks, and were coated with a film of malachite. The geological character of the ground is certainly an unusual one for a connected vein : but trial works are now being ex- ecuted, and it is to be hoped that the enterprising undertakers may be successful. The ore found is decidedly verj' rich ; spe- cimens of it, which I examined, were pure grey sulphuret, containing 80 per cent, of copper. Such are the general features of the copper mines that have been, or are now, worked in Ireland, so far as I have been able to discover. Indications of copper have been reported as found in several localities, that I have not noticed, as I as- certained that no real workings had been made, and that the evidence of the importance of the indications, did not appear to be of sufficient weight to justify me in inserting them in the present work. In what has preceded it may be remarked, that I have spoken always of the quantity of copper ore raised in the Irish mines as being indicated by the returns of sales at Swansea. In fact, the facilities afforded in that locality for the economical smelt- ing of metallic ores are so great, that it has become the centre of the C()ppt'r trade ; and the ores of Cuba, of Cornwall, and OF IRELAND, 201 of Ireland, mostly converge to South Wales, in order that the metal may be extracted. In estimating the circumstances of any locality where copper ore may be found, the means of con- veying it to the shore for exportation foi'm, therefore, an im- portant element : and fortunately almost all the districts in Ireland, in which copper mines exist, lie directly on the coast, or near our navigable rivers. The treatment of the copper pyrites for the extraction of the metal, consists in a long series of processes, alternately of an oxidizing and deoxidizing character, which have for their object to remove the sulphur and prevent the reduction of the iron of the ore, whilst the copper may be separated in the me- tallic state. These processes are altogether usually eight in number, and are performed in reverberatory furnaces, at very high temperatures. Hence the consumption of fuel is very great, and its cost makes up a large proportion of the ex- pense of the operation. I will briefly describe the nature of this process, as it is of considerable interest in a scientific point of view, and then point out the numerical estimate of its cost. The first object in the smelting process is to roast the ore in a current of air, so that the sulphur may be burned out, and the metals, copper and iron, may be oxidized. If the ore contain arsenic, or other volatile impurities, they also are driven off. Most of the sulphur passes away as sulphurous acid gas, but some remains as sulphuric acid united with the oxides of iron and of copper. If now this mixture were at once submitted to a reducing action, the metal obtained would be a mixture of iron and copper ; this is to be avoided, for such a product would be very intractable and difficult to purify. It is necessary to reduce the copper without reducing the iron, and for this, advantage is taken of the principle that the sili- cates of the metallic oxides are not reducible by contact with carbon. The quartz, which usually forms the vein-stone in copper mines, remains attached to the particles of ore in such quantity, as generally to constitute half its weight. Now when the roasted ore is subjected to a strong heat, the silica of the quartz unites with the metallic oxides, and forms silicates ; but 202 INDUSTRIAL RESOURCES as it is wished to form oaly silicate of iron, the oxide of copper must be protected, and this is done by adding to the roasted ore, lime, or else a quantity of the slags formed in a subsequent process, and which consist principally of oxide of iron. Either of these being a stronger base than the oxide of copper, com- bines with the silica in preference, and there is thus formed a fusible slag containing silicates of lime and iron, and a very impure metallic copper which flows underneath. In this part of the process also, the residual sulphur is expelled, for the silica, in combining with the metallic oxides, expels the vo- latile sulphuric acid they had previously retained. The mass of impure copper thus gotten, and termed matt or coarse metal, is purified by a series of roastings and reduc- tions, which act on the principle that iron is more oxidizable than copper. The matt being melted is oxidized by the air, the iron oxidizes first, and the scoriae of oxide which form on the surface of the molten mass are skimmed off. Sometimes sand is added, which combines with the oxide of iron, and prevents any of it from being accidentally reduced by the flame. In this way the iron is gradually all worked out, and the copper assumes the characters by which it is known to be ab- solutely pure. These processes are best carried on with an ore which con- tains from 8 to 10 per cent, of copper, and hence the advan- tage which a central smelting district like Swansea presents, of enabling the metallurgist to mix together ores of various origin and richness, so as to produce accurately the composi- tion with which his process succeeds best. Thus the poor ores of Wicklow and of Cornwall serve to dilute the richer ores of Cuba, of Berohaven, and Knockmahon. Such a mixture pre- pared for smelting, and analysed by Mr. Richard Phillips, was found to consist of Copper, 9 Iron, 20 Sulphur, 14 Earthy materials, 57 100 OF IRELAND. 203 This had been formed by mixing together equal parts of Cornish ores, of ores from Knockmahon, and of Wicklow ore from Connoree. The fuel consumed in producing a ton of metallic copper is usually reckoned at from 18 to 20 tons. The value of the ore of course varies with the price of copper, which recently has fallen very much. At 8^ per cent, of metal the weight of ore necessary is 12^ tons, which may be considered as averaging £6 10s. per ton. The coals cost in Swansea usually 6s. per ton, 20 tons therefore cost £6 sterling, and as the ton of fine copper is now worth about £90, the cost of fuel makes up about 6| per cent, of its value. If the copper ore raised in Ireland were smelted on the coast, the price of fuel would be certainly double that in Swansea, and make up 13^ per cent, of the cost of the product. This precludes altogether the introduction of this industry amongst us, but I shall have occasion to notice certain operations to which the ore might be subjected before exportation, and from which considerable advantage might be derived. Mr. Strom has recently directed attention to the great saving of fuel in smelting copper ores by the method followed on the Continent. This consists in roasting the ores in heaps in the open air, and then smelting them in blast furnaces, not unlike the high furnaces of the iron manufacture, but of smaller size. In this manner the fine copper is produced with an expenditure of 13^ tons of coal, almost exactly two-thirds of the quantity consumed in the reverberatory ftirnaces employed in England. He states also that there is actually a smaller loss of copp^ during the operation. The money saving by this method should be in Swansea £2, or in Ireland £4 per ton of fine cop- per, and it is hence a subject well deserving consideration. In order to complete this sketch of the industrial condition of the copper mines of Ireland, I shall add the following resume of their produce, as compared ^vith that of the English mining district of Cornwall. The total quantities and values of copper ores from Ireland sold in Swansea were in 204 INDUSTRIAL RESOURCES 1836, . . 21,819 tons, . . £163,864 10 value. 1840, . . 19,580 „ . 127,910 13 „ 1843, . . 17,509 „ . . 117,625 4 „ The apparent diminution arises from the causes described in page 187, and which have principally affected the returns of the Wieklow district.

It remains for us to apply the same energy and perseverance to the development of our mineral resources. 2nd. Of the Lead Mines. Lead is even more extensively diffused through Ireland than copper, and is found in a much greater variety of rocks, so that I shall not endeavour to trace the distribution of our lead mines in any geological point of view, but describe them in the order of their practical importance, first noticing the constitu- tion of the ores which they usually contain. •That which is pre-eminently called lead ore is the yaleiia or sulphurct of lead. In 100 parts it contains Lead, 86-6 Sulphur, 13-4 Its colour is bluish grey; its lustre brilliant metallic: it crystallizes in cubes, and when broken generally forms cubical fragments ; but its structure varies very much. The carbonate of lead, or white lead ore, is occasionally found in quantity, but many mines do not contain it at all. It forms white crystals or masses, which consist of OF IRELAND. 205 Lead, 77'6 Oxygen, 60 Carbonic acid, 16-4 100 The sulphate of lead is, like the carbonate, white and crys- talline, but is distinguished from it by not dissolving in dilute nitric acid. It contains Lead, 68-4 Oxygen, 5-3 Sulphuric acid, 26-3 100-0 This ore is of still less frequent occurrence than the carbo- nate. Both may be considered as only accidentally present, the lead ore, for which a mine is worked, being always the galena. The granitic district of Dublin and Wicklow is intersected by a great number of veins containing ores of lead ; they lie along its eastern boundary, and cross, in an oblique direction, the juncture of the granite with the mica-slate. Veins have been worked along this line at Dalkey, and Killiney, on Bally- corus, at Powerscourt, Djouce, Lough Bray, Lough Dan, Glenasane, Glendalough, Glenmalur, and Shillelagh. Of these many have been found ultimately unproductive, and the only portions of this district which it is necessary to describe in detail, are those of Glendalough, of Glenmalur, and Bally- corus. A The mountains which enclose the lake and ruins of the Seven Churches consist of granite, through which run numerous veins of quartz, associated mth which are found the ores of lead, and in some instances traces of copper. Their general distri- bution is as follows. At the head of Glenasane, a little above the junction of the granite and mica-slate, a vein of quartz six feet wide, with blende, galena, and some copper pyrites, passes nearly from east to west, and were it continuous would join the veinofLuganure. The latter, the most important in the district, runs altogether in granite. It crosses the mountain Coma- 206 INDUSTRIAL KKSOUKCES derry, and has been accurately traced through a course of 900 fathoms ; its ascertained depth being 180 fathoms. This vein is usually five feet wide, but in one place it expands to twelve feet. The ju'incipal vein-stone is quartz. The granite in con- tact with the lower surface of the vein is generally soft and decomposed to a depth of from one to three feet. This vein yielded, according to Mr. Weaver, in some portions of its course, per cubic fathom, from three to four and a-half tons of galena, which is found either in layers parallel to the walls or in disseminated masses. White lead ore is not uncommon. There are also found sulphuret of zinc, copper pyrites, and phosphate of lead. The produce of this vein usually yielded seventy per cent, of metallic lead. A few fathoms west of this is another vein in the granite ; it is three feet wide, and con- sists of quartz with galena and white lead ore. The Glendalough vein ranges east and west, crossing the glen obliquely. Its course is down the southern flank of Coma- derry, and it reappears high on the mountain of the opposite side, south of the Waterfall. Its line has been traced for about half a mile, it appears to range far into the granite on the western side, but not to penetrate much into the mica-slate. Its width varies from five to seven fathoms. The great mass of it is quartz. It contains numerous minerals, principally galena, with copper pyrites, sparry iron, and sulphate of ba- rytos. The lead ore of this vein produces 70 per cent., and the copper ore gave from 10 to 15 per cent, of metal. In the W^aterfall and ravine at the head of Glendalough are smaller %eins, in which lead and copper ores have been found, but on which no workings have been carried on. On the Luganure vein, and on some smaller veins discovered on both sides of Glenasane, and which are probably outliers from it, a number of shafts have been- sunk and very extensive workings made. The old Luganure mine, as well as the Hero mine, have ceased to yield any produce, but the mine of Rip- plagh, on the east, and one on the; western side of the glen, lately opened at the base of Luganure mountain, are now actively worked by the Mining Company of Ireland, and yield a very fair quantity of ore. They are termed the Luganure mines. OP IRELAND. 207 The state of activity of their operations and their amount of produce are shewn by the quantity of dressed ore obtained, which was In 1842, 675 tons. In 1843 547J „ The ore raised is dressed by hand labour and machinery, to which motion is given by water power derived from the rivulet which passes through the glen. To this Lough-Nahagan serves as a copious reservoir, which has been rendered fully available to the purposes of the dressing works. The dressed ore is brought on cars to the Company's smelting works at Ballycorus, where it is worked up along with ores from other sources, by processes to which I shall, after a little, return. The metallic lead is manufactured into sheet or pipe, so as to suit the markets in which it may be sold. The lead mine situated on the hill of Ballycorus, contains two lead veins, which at the surface are nearly parallel, and cross the junction of the granite and mica-slate, which takes place on the summit. In the workings these veins have been found sometimes to diverge, and at others to coalesce, and were then in every case found to yield valuable bunches of ore. These veins had latterly, however, become unproductive, and although some limited explorations were still carried on by the Mining Company, this mine was not reckoned as being at the present time in actual work ; but within the last few months, it has assumed a new interest, by the vein of lead ore being found to contain a rib of native silver, the condition of which will be described more fully, further on. In its vicinity are situated the Mining Company's smelting works, to which all their lead ores are brought for the purpose of their reduction and manu- facture. On the northern side of Glenmalur, where the granite and mica^slate join in Lugduflf mountain, a powerful metalliferous vein presents itself, forming an acute angle with the course of the valley. It has been traced for above 400 fathoms, but probably extends much farther. The vein, as described by Mr. Griffith, is, on an average, fifteen feet thick, and excepting 208 INDUSTRIAL RESOURCES where there are bunches of ore, is divided into five parts. There are three feet of a soft slaty vein containing much talc, then a vein of white quartz, from one to three feet thick, which usually contains ore, next three feet of soft talcj' matter, simi- lar to the first, then two feet of quartz, in which most of the ore has been found, finally, a third layer of the soft talcy matter extends to the opposite wall of the lode. The lead ore of this mine is considered to be unusually free from zinc and antimony. It has yielded very abundant produce, several large bunches or masses of ore having been met with in the course of the workings. The productiveness has, however, latterly diminished. The number of persons employed on it is at present about thirty. On the same and on the opposite side of Glenmalur, several other veins, containing indications of lead, have been discovered, but no serious trials of them have been made. The clay-slate districts, which have been found so rich in copper, yield also abundant indications of lead, but, up to the present time, few of the mines that have been worked have yielded a profitable return. Of very few of them have there been as yet detailed examinations made, and hence it will be sufficient to notice them succinctly. At Caime in Wexford, the clay-slate is penetrated by a vein of quartz, ramifying very much, and bearing galena, white lead ore, sulphuret of zinc, with copper and iron pyrites. This vein is of considerable magnitude ; at forty-seven fathoms in depth, being twelve feet wide. Several years ago some quantity of copper ore was exported from this mine, and also large quan- tities of galena, but it was abandoned until a few years back, when its working was i-esumed by the Mining Company of Ire- land, but it is questionable how far its working may be profita- ble at deep levels. The lode is considered to yield about three tons of ore per fathom. The quantity of dressed ore obtained was, In 1842, 503 tons. In 1843, 270 ,, The ore usually contains "5 per cent, of metal, and is sent to OF IRELAND. 209 Ballycorus to be smelted. The number of hands employed is about 130. In the clay-slate of the north of Ireland, which spreads over the Counties of Louth, Armagh, and Down, several lead mines have been opened. In Armagh at Derrjnioos, a vein of lead was worked for several years by the Mining Company of Ireland, but finally abandoned. It yielded about 200 tons of dressed ore per annum. It was in this mine that were made the trials of turf as fuel for the steam engine employed in draining, which have been given in a former chapter. At Keady, in the same county, a vein of lead was found, of which Sir Charles Coote, in his Survey of Armagh, speaks in the following words : " This mine is on the estate of the College of Dublin, the lands are held by the Earl of Farnham ; the late Earl expended large sums in sinking and working, but made no profit of it. It is rather wonderful, and indeed proves the value of these mines, that he was not a considerable loser, as he had no active part- ner to superintend works under ground which he never saw himself. The vein is so rich and abundant, it would be well worth the attention of the monied undertaker." This atten- tion, as far as I can learn, has not since been given to that district. In Down, at Clonligg, near Newtownards, is a lead mine which is at present worked to a moderate extent. At Dun- drum, in the same county, a vein containing lead ore has been discovered, and superficial trials of it made. In the slate districts of the south of Ireland, veins contain- ing lead have been found at Ardmore in Waterford, and in several of the localities already mentioned as the depositories of copper ore. In Kenmare only is the extraction of lead ore at present actually carried on, and the circumstances are so similar to those described in page 196, for the mine of copper of the same place, that it is unnecessary to notice it further. The workings for lead carried on at Silvermines have been also sufficiently described already in page 199. There is nothing doing at pi'esent in that locality. In Ringabella creek on the southern coast of Cork, a vein occurs in the carboniferous slate, in which lead ore is found. p 210 INDUSTRIAL RESOURCES It has boen worked from timft to time by different persons. Its frequent abandonment does not speak much in its favour, but may have been due to want of knowledge or of enterprize on the part of the undertakers. Lead ore has been met with in several localities in the granite and mica-slate district of Connemara, but no workings hitherto entered uijon. In the same class of rocks in Donegal, lead veins have been found, and at Kildrum a mine was worked for some time by the Mining Company of Ireland, but it has been given up, and is, I believe, now idle. The limestone formation affords numerous indications of metallic contents, principally lead: copper pyrites, iron pyrites, and blende, have been found in small quantities, but galena alone has been met with in such quantity as to be profitably worked. The vein stone is usually calcareous spar, accom- panied by brown spar. The limestone of the centre of Ireland is, as Mr. Weaver remarks, singularly ill-calculated for the conducting of mining operations. It occupies the lowest and richest part of the country, and frequently supports a great depth of alluvial matter and soil. Hence the drainage of the mines becomes difficult and expensive, and the cost of fuel, and damage to the land, are important. The number of localities in which lead ore has been found in the limestone district is considerable, and some of the deposits have proved of value. Near Dublin, at Clontarf, a vein of lead ore, accompanied by blende, appeared on the sea shore, where it was WTought until the tide broke in on the workings, and the mine became filled up with water. In almost every direction round Dublin small veins of galena have been found in the calp, as at Dol- phin's Barn, Castleknock, Kilmainham, &c., but none of them maintained their produce to any depth, or were of a magnitude which would justify any extensive trials. In the counties of Meath, at Beauparc and Athboy, and of Kilkenny, in several localities, lead ore has been found, but only at Floodhall was a mine ever actually worked. From it considerable profit is said to have been derived, the lead ex- tracted having been very rich in silver. No workings are at present carried on. In Longford, close to the town, load ore OF IRELAND. 211 has been raised, and in Kildare, at Wheatfield, on the banks of the Grand Canal, a large deposit of pure galena was found, in connexion with a vein of calcareous and brown spars, on which extensive works were erected, but after some time the store of mineral was exhausted. The lower limestone of the east of Clare has been found to contain several very large deposits of galena, which have been worked by Mr. Taylor with great success. From his account of them given to the Geological Society of Dublin, the follow- ing is extracted : Milltown Lead Mine " The Milltown lead mine in the ba- rony of TuUy, in the county of Clare, is probably one of the oldest mines in Ireland. At one time, it may be supposed, that there must have been a rich deposit, the ancient excavations being very extensive. " The Royal Irish Mining Company took a lease of it about twelve years ago, but after partially clearing the old workings, and driving a level for a short distance into the north side of the mine, they abandoned the speculation, after raising above eleven tons of ore. " In the year 1836, a grant of this mine was taken from the present proprietors, Anthony Colpoys and George O'Callaghan, Esqrs., by John Taylor, Esq., of London, whose name is so well known, and deservedly identified with the mining interests of England. " The ancient workings were now completely cleared, and some rude tools discovered, such as oaken shovels and iron picks, the latter of an extraordinary siee and weight ; also the remains of fires, which had been evidently made use of to crack and loosen the masses of calcareous spar and carbonate of lime, in which the ore of this mine is chiefly imbedded. The spar is very beautiful, being perfectly white, and much of it transparent. " After considerable labour and expense, Mr. Taylor's agents were disappointed in the expectations they had formed of making fresh discoveries of sufficient importance. The works, therefore, were abandoned in April, 1838, after rais- ing forty tons of ore, which, upon an average, yielded about p2 212 INDUSTRIAL RESOURCES 75 per cent., of lead, and 37 ounces of silver for each ton of ditto. " Within half a mile of this mine, upon the estate of James Moloney, Esq., of Kiltannon, are the celebrated Tomines, or immense natm'al vaulted passages of limestone, through which the River Ardsullas winds a most extraordinary course. The place is extremely curious, and the stupendous masses of rock forming a gigantic roof over the river, present a scene of magnificence which can never be forgotten by those who have viewed it. " The same river loses itself again among the cavernous strata of limestone rocks near Quin, and afterwards passing through the picturesque lake of Dromoland, falls into the Fer- gus, below Castle Fergus." Kilbricken Lead Mine, in the Barony of Bunratty and Parish of Dura — " In the year 1833, attention was awakened by the circumstance of the accidental discovery of lead ore, by persons in his employment, on the estate of John M'Donnell, Esq., of New Hall, near Ennis. " The first specimens were found by persons while cutting the new line of road between Moriesk and the new town of Clare ; after which more important discoveries were made on the Farm of Moniuve, by the tenant, John Egan, while cutting a drain through his bog. " The specimens and description of soil and calcareous spar, in which these stones of ore were discovered, having been submitted to the inspection of Mr. Taylor, in London, he de- termined on sending agents to examine the district, and in consequence of their report, some experienced miners were despatched from England, through whose exertions about twenty-five tons of lead ore were raised and shipped, which sold at a very high price, being found to assay for lead 70 per cent., and for silver 120 ounces per ton. " At this time, however, the rush of water from the sur- rounding bogs was found to be an insuperable obstacle to further progress, without the aid of machinery, and it was then determined to stay the proceedings until a steam engine of sufficient power to contend against the difficulty, should OF IRELAND. 213 be despatched from England. This engine was erected and put to work in 1837 ; operations are now going on upon an extensive scale, and great hopes are entertained of a success- ful result, but it is too soon to form an accurate opinion upon this point. " This mine is situated within two and a half miles of Quin, and is about six miles from Ennis." Ballyhickey Lead Mine, in the Parish of Clooney and Barony of Bunratty " This is the richest lead mine which has been discovered in the coimty of Clare, and is upon the estate of Hugh Singleton, Esq., of Hazlewood; in a direct line of dis- tance it is about a mile and a half east from Kilbricken, and here lead ore was discovered nearly at the surface. Operations were commenced by Mr. Taylor's agents in the Autumn of 1834, and with decisive success, so much so, that an export of 125 tons took place the following spring, and from that period to the present, not less than 2300 tons have been shipped from the port of Clare to the River Dee, averaging by assay, 77 per cent, for lead, and 15 ounces for silver in the ton of lead, and a considerable quantity of ore is still raised and shipped monthly." " The three deposits of ore above mentioned, occur in large veins of calcareous spar, which traverse the limestone rock of this country ; they differ from any hitherto observed in the mining districts of England and Wales, and indeed upon the Continent of Europe. The veins of spar are of immense width ; in places from twenty to thirty feet, and they run ge- nerally a little to the north of east and south of west. " The quantities of ore found at Milltown and at Kilbricken are so small, and the masses of spar so large, that it is not easy to trace the intersection of veins or branches at the points of deposit, as distinctly as at Ballyhickey. There the bunch of ore, the richest probably that was ever seen, taking the number of tons raised, and the number of solid fathoms of ground broken into account, occurs upon the intersection of two veins. The main vein runs N. E. and S. W., and its tributary falls in the angle of 45°. At this point the mass of ore was from sixteen to twenty feet wide, in places, almost 214 INDUSTRIAL RESOURCES pure ; in others, raised with sulphuret of copper and zinc. The total length of the rich branch was about forty feet, and it is still orey at the depth of eleven fathoms ; how deep it may be worth pursuing is a question yet to be solved. The quan- tity of water is not considerable, although the mine is situated in the middle of a boggy piece of land. An engine, however, has been erected, for the double purpose of grinding the ores, and pumping the water. Fresh intersections of veins are still sought after, being the places at which only other deposits are expected." The lead ore, as dressed for smelting, usually contains from 60 to 70 per cent, of metallic lead. This is combined with sulphur, and mixed with the material of the associated minerals, prin- cipally quartz, and often sulphate of barytes. The mode of extracting the metal is simple : by calcining the ore in a cui*- rent of air, at a temperature just below redness, the sulphur and metal both become oxidized, and the greater part of the former is expelled as sulphurous acid gas. On then increas- ing the heat and excluding the air, so that the combustible gases of the fuel act directly on the roasted ore, the oxide of lead formed in the first stage of the process is reduced, and the metal separates. The smelting is usually carried on in a reverberatory furnace, by which the oxidizing and reducing processes are effected in turn, by regulating the admission of the air. The bed of the furnace is dished, so that the melted lead trickles down from all parts of its surface to the centre, and when it has collected in proper quantity, is run off by an aperture in the side of the fiu-nace, into moulds, where solidi- fying, it forms the pig lead of commerce. There are two cir- cumstances of this process which require further notice. First, the draught of the furnace carries up into the chimney a very sensible quantity of the roasted ore, which would be a source of serious loss, were it not that the chimney is provided with a considerable extent of horizontal passages, in which the fine powder of the lead ore deposits itself, and at certain intervals these flues being cleared out, the matter found there is added to the other products of the ore, and all smelted together. Second. Although, in roasting the ore, the greater part of OF IRELAND. 215 the sulphur is burned out, yet a quantity ofit is converted into sulphuric acid, which unites with oxide of lead and forms sul- phate of lead. This is not further changed by calcination, but when the reducing fire is applied, this sulphate of lead, losing all oxygen, would reproduce sulphuret, and thus so much of the material be brought back to its primitive state. To avoid this, the smelter adds to the roasted ore a quantity of lime, which combines with the sulphm'ic acid and sets free the oxide of lead, which is then perfectly reduced. The lime is also useful in preventing the silica (quartz) present in the ore, from seizing upon oxide of lead, and thus producing loss. It takes the silica, as it does the sulphuric acid, from being a stronger base. The slags which are formed in this process consist of the earthy matters of the ore, melted up with the lime which had been added. They also contain a large quantity of lead, so that they are set aside, and being mixed with the material extracted from the flues of the furnace chimney, are smelted in an operation by themselves, and the metal they contain ex- tracted. Third. A great deal of the success of this mode of smelting depends on a very curious reaction of that part of the ore which has been fully roasted, on that which has not been altered. It will be easily understood, that when sulphuret of lead and oxide of lead are melted together, the sulphur of the one and the oxygen of the other unite to form sulphurous acid gas, and the lead of both separates in the metallic state. Expressed in che- mical symbols, Pb S and 2 Pb O give SO, and 3 Pb. The pro- portions by weight being that 120 parts of sulphuret of lead, and 224 parts of oxide of lead, give 32 parts of sulphurous acid, and 312 parts of metallic lead. A similar reaction takes place when sulphuret of lead and sulphate of lead are ignited together ; all sulphur and all oxygen are evolved as sulphurous acid, and all the lead separates. The weights engaged are 120 parts of sulphm-et of lead, and 152 parts of sulphate of lead, and there are produced 64 parts of sulphiu-ous acid gas, and 208 parts of lead. In chemical formula; : Pb S and Pb O SO^ give 2 Pb and 2 SO,. Now these processes of reduction are 216 INDUSTRIAL RESOURCES independent of the consumption of fuel. The surface of the ore having been suitably roasted, so as to generate oxide and sulphate, it is mixed thoroughly with the unaltered mass be- neath, and the reactions occurring, metallic lead separates in abundance, and sulphurous fumes pass off. In order to afford an idea of the influence which the cost of the fuel used in the smcilting processes exercises on the value of metallic lead, I shall add the numerical results, which have been obtained at Lord Grosvenor's Works at Holywell in Flint- shire, and at the Works of the Mining Company of Ireland, at Ballycorus, near Dublin. The ore smelted at Holywell averages 71 per cent, of metal, and is found to yield, by the process above described, in prac- tice, C(5 per cent., so that the loss is but 5 per cent. The combustion of coal during the process is half a ton per ton of ore, which amounts to 15 cwt. 17tt) for each ton of metallic lead. At Ballycorus, where the lead ores from the mines worked by the Mining Company of Ireland are smelted, and the lead wrought into sheet and pipe, litharge and shot, the quantity of ore worked up in the year 1843 was : From Luganure mines, 547^ tons. From Caime mine, 270 ,, which delivered 10288 pigs of lead, weighing 588 tons, 4^ cwt., equivalent to 72 per cent. The total fuel consumed in the smelting operations was 551 tons of coal and eight tons of coke, making together nineteen cwt. of fuel per ton of lead. The pig lead being now sold at £17 per ton, the coals at I2s., make up 3^ per cent, of the cost of the reduced metal. The quantity of fuel given, as consumed in smelting the lead at Ballycorus, includes that employed in a process not per- formed at Holywell, which is the extraction of silver from the m(?tallic lead. This is now practised to a very considerable extent. In noticing the lead mines of Clare, the fact of their yielding silver has been mentioned, and almost all the Irish galenas are argentiferous. So rcmai'kably is this the case. OF IRELAND. 217 that formerly the lead smelted in Ireland was so hard and brit- tle, that it was accounted inferior to the English in our own market, and would not be bought, but was sent over to Eng- land and to Holland to be refined. This purification consisted in removing from it the silver which it contained, and then it was sent back fitted for its proper uses, and was sold at a higher price. These processes are now all carried on at Bal- lycorus, and so perfectly as to leave nothing to be desired as to economy of method and purity of product. It is conducted as follows : The lead having been obtained by the ordinary smelting pro- cess, it is remelted, and the concentration of the silver effected by the very ingenious plan invented by Mr. Pattinson. This is founded on the fact that an alloy of lead and silver is more fusible than pure lead. Hence, the lead being melted, is al- lowed to cool very slowly, until it begins to solidify. What becomes solid contains no silver, and by removing the grains of lead as they form, with a perforated ladle, the silver is con- centrated in the portion which remains liquid, so effectually, that ultimately, after several repetitions of the process, the whole quantity of silver is obtained, united with about one-tenth of the lead, whilst the remaining nine-tenths of the lead is free from silver, and is sent to market. The rich portion of the lead is then cupelled. A shallow crucible, or capsule, is formed of bone dust and ashes ; in this the lead is melted, and then a strong blast from a bellows is blown across its surface ; the lead is oxidized, and the oxide of lead is partly absorbed by the porous cupel, partly blown off over the edge of the cupel, and being collected forms the litharge of commerce. This process is continued until all the lead is oxidized, when the dull film, which had throughout covered the melted metal, passes off, and the pure silver re- mains. It is allowed to solidify in the cupel, and removed from it when cold. The old cupels are broken up, and smelted with the slags to extract the oxide of lead they had absorbed. The quantity of silver contained in the lead ores of Ireland, so far as it has been experimentally ascertained, is as follows ; 218 INDUSTRIAL RESOURCES The proportions of silver to a ton of lead are generally found to be: From Luganure mine, Wicklow, ... 3 ounces, From Caime mine, Wexford, . . . . 12 ,, From Ballyhickey mine, Clare, ... 15 ,, From Kilbrieken mine, Clare, . . . .120 ,, From Tollyratty mine, Strangford, Down, 10 ,, The average produce of silver extracted from the lead ores of the mines worked by the Mining Company of Ireland during 1843, was seven ounces and a half to the ton of lead, and the total quantity was 4261 ounces, which sold for £1157 10s. 8d. The precise localities of the more important deposits of cop- per and lead ores, are marked on the map which represents the distribution of bog and the catchment basins of rivers.

LIST OF VARIETIES AND LOCALITIES OF MARBLES. Of THE Gold Mines of Wicklow. Towards the close of the last century native gold was ac- cidentally found to occur, disseminated in the bed of the streams which descend from the northern flank of Croghan Kinshela ; a mountain which lies on the confines of Wicklow and Wex- ford, and at the junction of the granitic ridge with the clay- slate. Considerable quantities of gold were collected by the people. It occurred in massive lumps, and in small pieces, down to the minutest grain. One piece weighed twenty-two ounces ; another eighteen ounces ; others nine and seven oimces. The gold was found accompanied by other metallic substances dispersed through a kind of stratum, composed of clay, sand, gravel, and fragments of rock, and covered by soil, which sometimes attained a very considerable depth (from twenty to fifty feet) in the bed and banks of the different streams. Shortly after the discovery of the occurrence of gold, the business of its extraction was taken up by the Government, under the management of ISIr. Weaver and some others. The method followed was that usual in gold mining districts, of washing the clay or soil in vessels with water ; the metal, from 220 INDUSTRIAL RESOURCES its great density, settles domi, and the lighter earthy impuri- ties are decanted. The valuable material is thus concentrated by a succession of washings, until finally the operators are ena- bled to pick out the particles of precious metal. The further operation of dissolving out with mercury the particles of gold too fine to be recognized by the eye, was, in some instances, had recourse to. The total quantity of gold collected by the Government workings, in about two years, was 945 ounces, which was sold for £3675 ; but the cost of the workings, and of various trials made in search of the original deposit of the gold, exceeded this return, and the workings having been interrupted, were not again resumed by Government. It has been calculated that at least £10,000 was paid to the country people for gold, collected before the Government took possession of the works. This native gold is of a rich yellow colour, soft, and mallea- ble. Its specific gravity is 19. An assay of 24 grains of it, effected by Mr. Weaver, gave pure gold 22-58, and silver 1-43. Another assay of it, by Mr. Alchorn, Assay Master in London, gave, for 24 grains, 21| fine gold, 1^ silver, and three- eighths of a grain of an alloy of copper and iron. The localities that have yielded gold in the largest quantity are Ballinvally, Ballintemple, and Killahurler, all situated in the same valley. The gold is associated with magnetic iron- stone, sometimes in masses of half a hundred weight ; also iron pyrites, brown and red hematite, wolfram, manganese, and fragments of tin-stone in crystals, together with quartz. From the nature of these attendant minerals, of which most are known to occur in the quartz veins of the adjacent mountain, it was hoped that by tracing up the rivulets to their sources, and laying bare in various directions the underlying rock, the metalliferous veins might be discovered, from the dis- integration of which the sand and soil of the bed of the streams had been produced. All such trials proved useless, and the question as to the source from whence the gold of those streams in Wicklow has been derived, remains still un- answered. OF IRELAND. 221 A few years since this district was leased to a London Com- pany, under whose directions some workings were carried on, in a very imperfect and trifling manner, up to a short time since, when they were finally abandoned. Neither the intelli- gence nor the energy necessary for success in such undertak- ings appears to have been applied. It is questionable whether under any management this source of mineral wealth could be rendered profitable, and mines of the precious metals are certainly those which this country can best aiford to do without. In other localities in Wicklow particles of native gold have been found, as at Croghan Moira, at Ballycrea, and Ballyna- capogue, but the quantities were too trifling to be an object of practical working. There is no doubt but that sources of native gold were known to the Irish at a very remote period. The abundance of gold ornaments and weapons, which are so peculiar to this island, and for which no source by importation can be as- signed, is sufficient evidence of this, as well as the testimony of our ancient writers, descriptive of the use and manufacture of this precious metal. That it was much more abundant here than in England is shewn by the fact mentioned in Delarnes' History of Caen, that when, after the Norman conquest of the British Islands, treasure was exacted from both to the exchequer of Normandy, the tribute exacted from England was 23730 marcs of silver, but from Ireland 400 marcs of sil- ver, and 400 ounces of gold, an enormous quantity for those times. Native Silver has also been found in Wicklow in a bed of iron ochre in the upper ground of Cronebane. The particles were seldom so large as to be visible to the eye, but the silver was extracted by fusion witli lead, and subsequent cupellation. It was auriferous, containing thirty grains of gold in each ounce. This deposit has been long since exhausted. Since the publication of the first edition of this work an event of considerable interest to mining in Ii-eland has oc- curred, — the discovery of native silver associated with the lead ore in the mine of Ballycorus (page 207). The native silver. 222 INDUSTRIAL RESOURCES which is quite pure and filamentous in structure, forms a rib in some places half an inch in thickness, but usually thinning out from that and lying quite close to the thin vein of galena, for which some workings had still been carried on by the Mining Company of Ireland. The quartz rock around is im- pregnated with silver in minute particles to a considerable distance. The economy of working this native silver is, how- ever, bv no means yet decided. The great hardness of the rock in which it is contained, and the irregularity of its dis- tribution, render it a question of much uncertainty. The Mining Company are, as I understand, about to erect and carry on the necessary works with their usual energy and prudence. The occurrence o^ tinstone in Ireland is of very considerable importance, as this metal, indispensable in the arts, and of high price, is one of the most valuable elements of mineral in- dustry. Hitherto it has been found, however, only dissemi- nated through the auriferous soil of Wicklow ; no veins or workable deposits of it having been met with. Of the remaining metals of practical importance many have been found, and in some cases their mines have been worked in Ireland, but they have not attained much development hitherto. The oxide of manganese occurs at Howth in the vicinity of Dublin, in Wicklow, but more especially at Glan- dore, on the southern coast of Cork, where considerable quan- tities of the ore have been raised. In the Glandore mine, the principal variety of ore is the true peroxide ; the hydrated sesqui-oxide is also found. The ore occurs associated with veins of quartz. The rock of the locality itself is the upper clay-slate, of which so much of the mining district of the south of Ireland is composed. The earthy hydrated peroxide of man- ganese is of very common occurrence, but I do not know any locality in which its quantity or its quality would re 0-3 100-0 100-0 1000 100-0 100-0 It is hence seen that whilst certain ashes, as that of Fra- mont, could only act as a form of calcined marl, and hence be but moderately useful to vegetation ; others contain a great number of elements, as magnesia, potash, soda, sulphuric acid, &c., which may prove in the highest degree beneficial. Dif- ferences of this kind are probably the origin of the conflicting evidence as to the results of the application of such substances as manures, by which practical agriculturists are so much puzzled, and we thus see that before employing those matc- I'ials a correct knowledge of their composition should be ob- tained. OF IRELAND. 285 In none of the ashes above analysed was there phosphoric acid found, and as its presence or absence affects very mate- rially some of the most important actions of manure, Boussin- gault endeavoured to ascertain whether it was at all present. He never could detect it in turf ashes, yet Sprengel names it as a constant constituent of the turf ashes of Holland and Lu- neburg, in the pro^iortion of from one to two jier cent. I con- sider Boussingault the higher authority in such a case, which, however, is really one of the most difficult problems of chemi- cal analysis, and, therefore, it is very desirable that special investigations should be directed to that point in the examina- tion of the ashes of Irish turfs. The phosphoric acid so abundantly deposited in those parts of plants employed as food, is destined to the formation of the osseous skeleton of the animal, and on its death returns to the soil, to be again absorbed into the composition of plants, and become the material of the bones of a new race of animals. Phosphate of lime and other compounds of phosphoric acid are thus most essential elements of plants, and, under the form of bones, ground or otherwise prepared, hence become one of the most usual manures. It is to be feared that before very long considerable loss will accrue to the corn and other food crops of this country, from the deprivation of the soil of this essen- tial ingredient. The cattle exported from Ireland carry out in their bones a vast quantity of phosphoric acid derived from the soil. Of the cattle whose flesh is eaten in the country, the bones form a considerable article of export, as the attention of our agriculturists has not yet been awakened generally to the importance of restoring them to the soil. Let it be recol- lected, that in lib of bone there is the phosphoric acid be- longing to "iStb of wheat, or of 2o0lb of potatoes ; that this phosphoric acid is indisjiensable to the healthy growth of the plants and of the animals by which they are consumed, and hence will appear the vital importance to agriculture of pre- serving, as far as possible, these valuable materials, and re- turning them to the soil. The coast of Ireland furnishes vast quantities of valuable manure in the sand which is dredged from a greater or less 286 INDUSTRIAL RESOURCES depth in the various bays, and in the sea weed which is col- lected at low water. Of the sea sand there are two kinds, one containing intermixed abundance of small shells, univalve and bivalve, which in many cases contain then- living tenants, so that this sand used as manure supplies a very appreciable quan- tity of animal matter. Its general composition may, therefore, be understood, although as the proportions of its elements con- tinually fluctuate, a single analysis of it could have but little authority. The silicious sand usually amounts to from 30 to 60 per cent. ; the shells to from 20 to 50, and, beside carbo- nate, jdeld some phosphate of lime and of magnesia ; there is generally from 3 to 6 per cent, of animal matter, which yields nitrogen by its decomposition, and, finally, from 5 to 10 per cent, of water, which holds in solution common salt, and the other ingredients of sea water. This manure furnishes actu- ally thus a great variety of substances to the soil, and although its principal action must be analogous to liming, yet the far- mers are certainly right in preferring it to ordinary lime. Another variety of sea sand used as manm-e is the coral sand, which is found but in certain localities, as Bantry Bay, and some of the inlets of Connemara. It consists of silicious sand, intermixed not merely with ordinary sea shells, but with fragments of a material usually termed coral, but which natu- ralists now consider to be of vegetable origin. This, however, does not affect its chemical composition, as the oi'ganic matter, whether animal or vegetable, is very rich in nitrogen, and exceedingly active as a manure. The usual proportions of sand and coral fragments are each about 40 per cent. ; the remain- der being organic matter and water. The coral contains some phosphate of lime, and this variety of sand is popularly es- teemed as being much preferable to that more commonly found. Boussingault considers the quantity of azotized matter in it, as dredged on the French coast, where also it is much used for manure, such as to render it equal in utility to its own weight of farm-yard manure. Roundstone Bay is the principal depository of this kind of coral upon the west coast ; it there forms banks, and occurs of several species. As it has been separated under the name of OF IRELAND. 287 Nullipora from the true corallines, and its place in the scale of nature a good deal disputed, I thought it important to make an accurate analysis of the usual form of it (Nullipora poly- morpha), which might, at the same time, illustrate its scien- tific position and its agricultm-al value. I found it to consist of : Carbonate of lime, 77"31 Carbonate of magnesia, 7 ■54 Phosphate of lime, 0-37 Organic matter, 10-50 Water 4-28 100-00 The organic matter was foimd to contain a very decided quantity of nitrogen. That I may give an idea of the extent to which the shell banks on our coasts are available as sources of these ma- nures, I shall extract briefly some estimates of the quantities raised at Derry, and on the southern coast of Cork. The for- mer is taken from Captain Portlock's Report on the Survey of Derry and Tyrone, the latter from a most interesting commu- nication by Mr. Francis Jennings. '• The shell banks of Lough Foyle form, when the tide is out, extensive flats, which are firm enough to be walked on without any inconvenience, and they are resorted to by numerous boats for loads of shells, and though this system has been pursued for more than a century, they exhibit no appearance of a fai- lure in the supply. The shells hitherto examined are all of recent species ; and it becomes a question whence they came. There are engaged is raising the shells 285 men for 26 weeks, at 10s., £3,205 50 boys .... at 6s., 390 The cost of the labour alone is thus, . . . £3,595 There are annually employed about ninety-four boats, of tonnage from below eight to sixty tons. The aggregate ton- nage of forty-one of the largest boats is 1306 tons. The total 288 INDUSTRIAL RESOURCES quantity of shells raised each summer is about 59,496 tons, which on the shore immediately opposite the bank sell for Is. per ton ; but at Derry and Strabane for Is. 6d. to 2s. per ton. Altogether Captain Portlock considers the shell banks of Lough Foyle to be worth £5,000 per annum to the country. " They are particularly useful in bringing bad lands into cultivation, and in ameliorating stiff wet clays, deficient in calcareous mat- ter, being applied at the rate of from thirty to sLxty barrels per acre. They are preferred to lime, as warming and brittle- ing the land." In this the silicious sand is probably most use- ful by giving porosity to the clay. Mr. Francis Jennings, to whose union of zeal and scientific knowledge I am indebted for much information regarding the industrial condition of the south of Ireland, has kindly drawn up for me the following account of the use of sea sand as a ma- nure, along the coast of Cork. I present it without alteration, that its value and authenticity may not be lessened. " The harbours and coasts of the south and west of Ireland abound in a calcareous sand, which is employed by the agri- culturists for manure in very considerable quantities ; that r.aised in Bantry Bay and the west, is termed coral sand, from the similarity of its appearance to portions of coral, but is in reality a semi-vegetable ; that kind is, however, unknown in the harbours of Kinsale, Youghal, and the intermediate dis- tricts of the coast, which, from a microscopical examination, is composed of comminuted shells, pulverized rock, portions of the shells of the Crustacea, a)id in many cases no inconsiderable number of minute spiral and bivalve shells, containing the fish, either dead or alive. " To the large proportion of phosphate of lime contained in the crustaceous remains, and the nitrogenized matters of the fish, much of its importance, doubtless, is due. Its colour varies from a reddish brown to a blue and brownish black, dependant not alone on the remains of the shells, but also on the prevailing rock in the vicinity. The sand raised in the harbours of Cork, Kinsale, Oyster Haven, and Ringabella, is dredged from depths varying from about ten to thirty feet ; that taken in Youghal, and the bays and strands intermediate OF IRELAND. 289 between it and Kinsale, excepting those already mentioned, is shovelled from the strand into carts and boats, generally at low water, and then taken up the country to its various desti- nations. " In a few of those places already named, I have been able to ascertain, with tolerable precision, the average amount raised per annum, which from Youghal harbour and strand is about 300,000 tons, 130,000 of which are taken by boats, of various degree of tonnage, to the different landing places on the Bride and Blackwater, as far as Cappoquin. "In Oyster Haven, an inconsiderable creek west of Cork harbour, there are thirty-two boats, of about tM'elve tons bur- den each, employed in dredging sand, some of which make about 150 boat loads each, in the year. These principally be- long to the farmers, and the men, when paid in money for their work, earn Is. 4(1. per man for each cargo delivered, and a boat-load or two at the end of the season, as a perquisite, there being three men employed in filling and working each boat, which takes about twenty full dredges to complete its cargo ; in many cases the men are partly paid by the use of a portion of land for a sufficient length of time to raise a crop of potatoes. The sand can only be raised in calm weather, and the labour is very sevei'e. The annual amount raised in this creek is about 37,000 tons, and a boat-load, M'hen sold, brings, accord- ing to the weather, from 6s. Gd. to 7s. Gd. These data, in connexion with the quantity raised in Cork, Kinsale, and Ringabella, which is a very small creek off Cork harbour, are by no means accurate ; the amount in those places taken to- gether is, I am confident, considerably underrated at 1,000,000 tons. Much of that raised in Cork harbour is, after a water carriage of ten or twelve miles, taken into the country on one- horse cars by working farmers, a distance of ten and twelve miles on hilly roads, which affords strong evidence in favour of its value as a manure ; and it is placed on limestone ground as well as on the soil resulting from the decomposition of the old red sandstone and carboniferous slates. It is not, however, to be supposed that the raising of sand on the coast is con- fined to those places already mentioned. Every strnnd, nook. 290 INDUSTRIAL RESOURCES and bay to which access can be had, by either a horse with panniers, or a cart, is taxed to supply its quota of sand ; and in many places of small extent, I have seen over fifty carts taking it at low water ; that which is raised then being con- sidered the best, and only inferior to that which is dredged. When it is, therefore, considered the number of places from which sand is raised, an approximation can only be obtained by inquiries requiring no ordinary degree of care and at- tention. "The amount of carbonate of lime contained in the sand varies considerably ; some of a dark blue colour, from Oyster Haven, which I tried a few years ago, contained 65 per cent. " It may be inquired, is the supply inexhaustible? The an- swer, as far as regards the dredged sand, might probably be given in the affirmative, but in many places the strands, for- merly covered to the depth of many feet, at present yield none except after heavy gales, and the inhabitants must either give up its use, or resort to the dredge for a supply. The amount of sand to the acre varies according to its price. In those places where it is about 6d. per ton, 800 cwt., or 40 tons, is by no means an unusual quantity to be applied every season, for many years together. " In considering its agricultural value, the quantity of salt water it contains must not be omitted, for the calculations are made not as to the amount of dry sand, but the state it is in after some hours' draining ; moist to the touch, but not wet. From its daily increasing consumption, and great value when taken far inland, I believe it would form one of the most con- siderable branches of internal traffic, at least in the south of Ireland, if canals existed which would allow of its being for- warded at moderate charges." From a note furnished l)y the Duke of Devonshire's agent to Mr. Jennings, it appears that there are engaged in the pro- curing of sand at Youghal 363 horses, with carts containing 14 cwt. 18 donkies, with carts containing 7 cwt., each drawing twelve loads per week. OF IRELAND. 291 35 lighters, of 35 tons average tonnage, which take two loads per Aveek. And the total quantity of sand raised annually is estimated at 293,503 tons, in the harbour of Youghal alone. Along the coast, large quantities of seaweed are collected for the pui'pose of being applied as manure, especially for pota- toes. It is found that the deeper the water where it is taken up the more powerfully it acts. This is probably owing to its greater luxiu-iance, and containing in its tissue a greater mass of sea water, which yields valuable saline materials to the soil. Exact analyses of the seaweeds used in Ireland have not j-^et been made. Boussingault found those used on the coast of France to be the fucus digitatus and the fucus saccharinus. These contain, when fresh, about 40 per cent, of water, and the dry material contained from 1-58 to 2*29 of nitrogen. He considers it, when fresh, equivalent to about its weight of farm- yard manure. Latterly this material has been transported to considerable distances into the interior, having been first dried by exposure to the sun. Its saline constituents are, of course, those of sea water, muriate and sulphate of soda, and of mag- nesia, with traces of lime and iodine. Such are the manures which the existing pliysical structure of the country places at the disposal of the agriculturist. They are in origin and constitution principally mineral, and are usually poor in one important element necessary to the support of plants, nitrogen. I have already noticed that to certain plants the atmosphere is itself a source of nitrogen, but it is not so to all, not even to the most important ; the giving of nitrogen to the soil is, therefore, a most essential office of ma- nures. To effect this a variety of means have latterly been afforded to the farmer, as the nitrates of potash and of soda, the salts of ammonia, the decomposed excrements of sea birds, guano, and numerous other even more complex bodies, all of which serve the purpose, all of which promote the fertility of the soil and favour the growth of plants, when judiciously ap- plied, but none of which possess any real utility over the ma- nure available on the farm, suitable to every crop, and most readv in its action. To this manure it is, therefore, highly 292 INDUSTRIAL RESOURCES important for the economical farmer to direct attention, in or- der that correct ideas may be formed as to the care which it deserves, and the relation which it bears to the crops, and feeding operations of the farm. If we consider the final application of farm produce, it will appear that comparatively little of it is absolutely removed from off the ground, and that by much the larger proportion is consumed within the limits of the farm, in the provisioning and stalling of the various animals. The corn which is sold, or the animals which are sent to market, remove from the farm certain quantities of inorganic materials and of nitrogen, which must be replaced, in order to sustain its fertility, and the cost of replacing which must be considered a necessary and fair deduction from their money price ; but the straw of the corn crops, the tops of turnips and potatoes, contain a much larger quantity of those materials which need not be removed from off the farm, but, on the contrary, should be most care- fully returned to the soil, to serve for the support of future crops of plants. It is similarly with the produce consumed by the animals as food. Each day's food serves but to replace in its organization the materials which are daily thrown off from its frame. The dejections and excretions of the animal must, therefore, represent the food which it consumes, and thus by returning to the soil all such materials, the sustenance of the animal is really deprived of any power of diminishing the fer- tility of the soil. I do not here consider the case of fat- tening animals, but only such as are sustained in an uniform condition and health ; but the fattening does not affect the principle in any important degree. Now these various materials, the straw of the corn crops, the tops of the potato and turnip crops, the excretions and dejections of the animals sustained upon the farm, all mixed and subjected to the reaction which soon sets in amongst their chemical ingredients, constitute farm-yard manure. It is made up of the remains and products of every kind of crop : it con- tains, therefore, the elements of every kind of crop. Its state is continually changing, as it is more or less rotted, and hence no two specimens of it would probably agree exactly in consti- OF IRELAND. 293 tution, but still, as illustrating in a general point of view the nature of its elements, I shall add the results of analyses made by Boussingault of that which, in a half rotted condition, he puts out on his experimental farm. The manure, in its usual form, contains in average 79*3 per cent, of water, and 20*7 of perfectly dry material. The dry material contained : RICHEST. POOREST. AVERAGE. Carbon, Hydrogen, Nitrogen, . . . . , Oxygen, Salts and earth, . 40-0 4-3 2-4 27-6 25-7 32-4 3-8 1-7 25-8 36-3 35-8 4-2 2-0 25-8 32-2 100-0 100-0 100-0 The ashes of this manure contain in 100 parts : Carbonic acid, . 2-0 Phosphoric acid, 3-0 Sulphuric acid, 1-9 Chlorine 0-6 Silica, sand, and clay, 66-4 Lime, 8-6 Magnesia, 3'6 Oxide of iron, and alumina, 6*1 Potash and soda, 7-8 On comparing this with the analyses of the ashes of various plants, given in page 276, it will be at once evident, that every constituent which they require is present in the farm- yard manure. It is, therefore, of the most vital importance to those whose livelihood depends upon the produce of their farms to economize as completely as possible this valuable ma- terial. A dung heap formed on the ordinary ground of the farm-yard, allows of the escape of the most valuable portions of the manure by drainage through the porous soil. By ex- 294 INDUSTRIAL RESOURCES posui'e to the weather during wet seasons the most active of its elements may be washed away. These disadvantages may be removed at very trifling cost by the adoption of such modes of collecting and preserving the manure as are employed in other countries. The dung heap should be formed upon an impervious floor of brick-clay or of cement, this to dip towards the centre, so as to form a shallow tank, towards which the floors of the various stables should have such inclination as would enable the drainings to be conveyed by suitable chan- nels to the central tank. By such an arrangement nothing goes to waste; the liability to loss by rain is obviated, and even the smallest farmer will very soon find the cost and trou- ble well repaid by the improvement, as well in the quantity as in the quality, of his stock of manure. I am not disposed to undei'rate the importance of the various artificial and foreign manures, the effects of which on the fer- tility of the soil have been in many cases wonderful, often by their activity jjroducing results to which the farm-yard ma- nure would be incompetent, and by their portability presenting, in many localities, a real advantage. Nevertheless, in the ex- isting state of education in this country, it is, as I conceive, far more useful to point out to the struggling farmer how to take advantage of the materials which now run to waste about his stables, than to send to him to lay out ready money, of which he generally has so little, for a fertilizer, of whose spe- cial properties and nature he is probably quite ignorant, and which has seldom any great advantage over well prepared farm-yard manure.

I HAVE SO far considered the exhaustion of the soil by plants, with a view to the restoration of the deficient ingredients through the agency of manures. There is, however, another mode of restoring fertility which is of practical importance, as it has led to the greatest of all improvements in liusbandrj', the rotation of crops. A soil which has been exhausted be- comes restored by lying at rest for a certain time, particularly if it be well broken up and fresh surfaces be exposed to the action of the atmosphere, in fact then by the decomposition of the mineral masses which the soil contains, a fresh soil is pro- duced. The organic remains of the former crops become also rotted, and assume a form suited for the nutrition of young 296 INDUSTRIAL RESOURCES plants, ami thus after a season's fallowing, still more after lying out of cultivation for some years, the soil resumes a very considerable degree of fertility. But it is evident that this process entails considerable loss by the land being so long idle, ' and it becomes of great importance to the farmer to make some use of the land, whilst this process of regeneration is going on. This is actually done by changing from one kind of culture to another ; whilst the land is recovering from the ef- fects of one plant it is capable of sustaining a plant which does not act upon it in the same way, and after this a third, dif- ferently exhausting from either of the others, will give a course or rotation of three years, during any two of which the ground is recovering from the exhausting action of the plant grown during the third. I take this only as an example, for it is found that three years is too short a term to be of much prac- tical utility. In selecting the plants adapted for such a rotation, we must be guided by their chemical composition, and by their mode of growth. The results of both, however, lead to the same con- clusion. In addition to those elements which arc common to all plants used as food, certain plants are remarkable for the great quantity of silica they take from the soil, such are the grasses and corn plants ; certain others for the potash they take up, such are turnips, the beet, the potato ; others again for the quantity of lime, as the pea, vetch, clover, tobacco, &c. Such are the kinds of plants that should succeed each other in a rotation, and the proportionate action of each class may be judged from the follo\ving table derived from Liebig's investi- gations. From a space of land of 247 acres, he found there were taken up by ALKALINE SALTS. SALTS OF LIME AND MAGNESIA. SILICA.

WHKAT. BEET. 1171b 112ib 37ftb. The reason of tlie beat taking so little phosphoric acid is, that it is not allowed to form its seed, and in all plants it is in the seed that the phosphates are principally deposited. From these numbers it is evident, that on such a field, if by the gradual decomposition of its soil it could furnish but 200tb of alkaline salts, and 200lb of lime and magnesia salts each year, we could grow upon it but half the proper crop of beet, for a full crop would require 3601b of alkaline salts, and also only a half crop of peas, for the full crops would require 3711b of lime and magnesia salts. The continuous culture of either plant would, therefore, be most improfitable and injm-ious, but if we cultivated beet one year and peas the other, the soil would have two years to prepare the materials which each crop would require to take up in one. There would be available 4001b of each kind of salts, and thus so far from exhaustion, there should be a surplus steadily increasing the fertility and augmenting the produce of the soil. As it is seen in the above table that the quantity of alkaline and earthy salts taken up by the corn crop (wheat) is so much less than that required for the other kinds of plants, and that the principal demand of the corn crop on the soil is for silica, of which we may consider it certain that no soil is in danger of being exhausted, it might appear natural to conclude that the corn crop should be that least detrimental to the ground, whilst it is well known to practical agriculturists, that white or corn crops are amongst the most exhausting. Their inju- rious action on the soil is, however, not so much due to the inorganic materials they take up as to the nitrogen, for which clement they are altogether dependent on the soil, whilst other kinds of plants act upon the atmosphere, aborbing nitrogen, and actually serving rather to enrich the soil upon which they grow, than in any degree to impoverish it. This in in fact what constitutes the remarkable relation between the white crops and green crops as members of a rotation. The former 298 INDUSTRIAL RESOURCES exhausting the soil of nitrogen, the other fixing in the soil nitrogen derived from the air, and thus preparing for the nu- trition of the corn crops that may succeed it. The complete illustration of this principle is due to Bous- singault, who has established it as well by experiments on individual plants in the laboratory as by the operations of an extensive farm. Thus on growing corn in artificial soil deprived of nitrogen, it was found that the plant, when arrived at its full maturity, contained only the nitrogen that had originally existed in the seed. On the other hand, on growing peas in the same way, the quantity of nitrogen in the mature plant was found to be much greater than had been in the seed, and for this there was no other source than the atmosphere. The following tables will shew how fully this result is borne out on the large scale. In a three years' cultivation of two successive crops of wheat manured and then a year of fallow, the produce was 3318 kilogrammes of wheat, and 7500 kilos straw per hectare, from 20,000 kilos of manm-e. Now taking these dry, the fol- lowing table shews their composition and the relation of their constituents. WEIGHT DKY. CARBON. HYDRO- GEN. OXYGEN. NITRO- GEN. ASHES.

On the other hand the carbon of the crop is nearly treble that of the manure, verifying, in an admirable manner, the atmos- OF IRELAND. 299 pheric origin of the carbon of plants, to which I have ah-eady alluded. Hydrogen and oxygen were also gained abundantly, and almost exactly in the proportions to form water. In contra-distinction to this corn culture may be placed the results of the continued growth of lucern for five years, fol- lowed by a crop of wheat, all at the expense of 44,000 kilos of farm-yard manm-e per hectare, put out on the land at the com- mencement of the period. These results were published by M. Crud, an eminent agriculturist. PRODUCE PER CONTENTS IN HECTARE. 1 NITROGEN.

Now as the residues of these green crops which remain in the soil, contain a corresponding quantity of nitrogen, they are the means of transferring to it such portions of that ele- ment as serve, if not fully to sustain its fertility, at least pre- vent the exhausting action of the white crops from being so soon or so severely felt. This is still more fully carried into effect when these crops, or the last growth of them, in place of being consumed, are ploughed into the soil, where they act as the best form of manure, their fresh and juicy structure facilitating theii* decomposition, and their composition being 300 INDUSTRIAL RESOURCES such as to provide almost every element subsequently re- quired. The substitution of these plants as sources of food for the animals of the farm, for the common, or as they are called, the natural grasses, has been one of the most important improve- ments in husbandry. The following table, which is collected from the best authorities, exhibits the quantity of actual nu- tritious material which is usually derived from an acre of land. CROP. WEIGHT. STARCH AND SUGAR.

L'360 1800 240 420 120 180 1720 2400 It is here seen, that turnips and carrots yield from five to seven times the actual quantity of food that the corn crops give, also that potatoes and clover yield twice as much, and as it should be always the object of the farmer to do as much as possible in a given time, on a given space of ground, he should fix his attention on those systems of culture which thus pro- duce the greatest quantity of food, and by the least exhaustion of the soil. Practical experience bears out fully the principles I have here endeavoured to explain. The Board of Agriculture in England directed special inquiries as to this point, and the re- sult led to the general conclusion, that one year of tai'es, rape, potatoes, turnips, or cabbage, gives thrice as much food as one year of medium pasture grass. In his very useful Lectures on Agricultural Chemistry, Professor Johnstone adopts the same general proposition, but he couples it with some money estimates which I consider it important to notice. He says: OF IRELAND. 301 " With the exception of rich pastures, it is said that land under clover or turnips will produce three tinies as much food for cat- tle as when under grass. If such a green crop then alternates with one of corn, the land should every two years produce as much food for stock as if it had been three years lying in grass, besides the crop of corn as food for man, and of straw for the production of manure." Professor Johnstone then proceeds to discuss the money value of the produce of simi- lar pieces of ground under such crops, and concludes, that ' ' although more food is raised by converting the land to arable purposes, and more people may be sustained by it, yet more money would be made by meadowing the land, where a ready market exists for the hay, where it is allowed to be sold off the farm, and where abundance of manure can be obtained for the purpose of topdressing the land every year." In order to arrive at this result he takes the prices of produce as follows : Hay, £5 per ton. Turnips, 10s, per ton. Barley, 4s. per bushel. WTieat, 7s. per bushel. Such a price for the hay could certainly be obtained only in exceptional cases : the other circumstances he mentions could only be realized in some few localities, and there is no doubt, but that, as a general principle in agriculture, the cultivation of green crops and artificial grasses is not only that by which the largest quantity of food is raised, but also that by which the greatest money return is afforded to the farmer. The natural moisture of the climate of Ireland, coupled with the general fertility of the soil, and especially that of the cen- tral district, where the subsoil is limestone gravel, produces a tendency to rapid growth of a sweet and luxuriant grass, in consequence of which the lands of these localities are almost exclusively devoted to grazing. It is certain that on the west- ern coast the humidity of the atmosphere is such, as on an average of years may present a serious obstacle to the ripening of corn crops and the safe completion of the harvest, but it is 302 INDUSTRIAL RESOURCES also certain that the tendency to adopt grazing in preference to tillage-agriculture, as a pursuit, is much more connected with the habits of the agricultural classes than with the nature of the soil, or the character of the climate. Mere industry has been in Ireland, for many generations, connected with the idea of a vulgar and depressed caste. The possession of the land with perfect idleness constituted in itself the criterion of res2:)ectability. The working of a tillage farm, even if more profitable, was thus fatal to the social position of the occupier ; whilst if he kept only a herd to mind some cattle, and spent his time and money in hunting and in drinking, trusting to protection for high prices, and to Providence to pay his debts, he mixed with the notables of the land and looked down with scorn ineffable on all that savoured of occupations vile, of industry or intelligence. Those ideas have been already verj' considerably disturbed. Prior to the introduction of turnip husbandry, and to the cul- tivation of the artificial grasses, it might be a question between the relative profits of grazing and of a very imperfect tillage, which gradually reduced the land to a condition of almost per- fect barrenness ; especially where the advantage of capital was altogether in favour of the former : but grazing is in reality but the production of food as well as tillage. An animal makes no food, it only assimilates that which is produced by the plants on which it feeds. A crop which produces three times as much food will, therefore, feed three times as many cattle, and it is hence unavoidable that as agriculture progresses the ordinary grass crops will be replaced by the more nutritious carrots, turnips, clover, &c. ; the animals, in place of roving over ex- tensive grounds which recal the idea of the prairie existence of a half civilized hunting population, shall be suitably confined, that their food may not be wasted in muscular efforts inconsistent with their ultimate perfection as food for man. The rearing of cattle will thus, in itself, become a branch, as it is really one most important, of tillage husbandry, and the manure thus ren- dered available will serve most efficiently to the production of corn and other exhausting crops. It is in such form that agri- OF IRELAND. 303 culture should finally be carried on in Ireland, and as it actu- ally is in other countries, where industrial intelligence has been more active. There are, however, many difficulties to over- come and prejudices to remove before that point can be arrived at, but in the mean time, every even trivial effort will lessen the obtacles on the way. The greater amount of food produced by the system of turnip and potato husbandry, is noticed by M. De Jonnes, in relation to its influence on the social circumstances of the people of this country, in words which are worthy of quo- tation. " On seeing what immense riches are obtained in England by the cultivation of the various species of green food, as supple- mentary to corn crops, and which are obtained; like them, by plough husbandry on a great scale, we are astonished at how recently this agricultural improvement, which has nearly dou- bled the means of subsistence, has been carried into effect. It was only in the middle of the seventeenth century, that turnips have been cultivated in England, and that the use of clover had been introduced. Scotland, more backward in every respect, obtained the potato culture only in 1739, and these precious vegetables were first cultivated in the Highlands in 1743. But it is particularly in Ireland, where the soil is fresh and fertile, that these new kinds of crops have prospered. In that island the potato gives an annual produce of 42,000 to 52,0001b, per hectare. (2-47 acres S.) On dividing that number by four to reduce it to the standard of nourishment which wheat affords, the hectare thus cultivated affords 10 to I3,0001b weight of subsistence. Newenham even considers three pounds of pota- toes as equivalent to one pound of wheat, and if so the 10,000lb of nutriment given by the hectare, as a minimum, when it is cultivated with potatoes, represent 45 hectolitres of wheat and the 13,000lb, are equal to 58. This is the double and treble of the best crops of wheat. This vast productiveness has mul- tiplied potatoes in Ireland, so that they form the basis of the subsistence of the entire country. That is an evil, for a social condition where each family, or nearly each individual, has his 304 INDUSTRIAL RESOURCES field, which furnishes his immediate nutriment, without any ne- cessity for marlsetiuf^, without the assistance of tho miller or the baker, without occasion to demand assistance from his neighbours, that society is deficient in the elements most ne- cessary to the progress of its civilization. From the great pro- duce of its corn crops it would be easy to establish a mixed system of nutriment in Ireland." There are few questions regarding agriculture which have been more keenly discussed, and there is certainly none more vitally important to this country, than the circumstances, as re- gards the magnitude of farms, and the mode of applying labour, under which the greatest amount of produce can be obtained from the land and the greatest quantity of employment given to the people. It is well known that in Ireland the subdivision of farms has been carried on to an extent which has been pro- ductive of most serious evils, moral and industrial. It is not within the objects of this work to discuss either the causes or the eflFects of the existing state of things, but first exhibiting the mere statistical facts of the number and size of farms, and some connected circumstances that will hereafter require com- ment, I shall proceed to consider the general principle of how the greatest quantity of produce can be obtained from the soil. By the returns of the census of 1841, the number of farms in Ireland, and their magnitude, was PROVINCES. FARMS FARMS. PROM 1 TO FROM .5 TO 3 ACRES. 15 ACRES. FARMS FROM 15 TO 30 ACRES.

This geogra- phical association is very much at variance with other social circumstances, and it will form just now an interesting object of inquiry. The wonderful revolution effected in the mechanical arts by the invention of spinning and weaving machinery, and the ap- plication of steam power, by means of which these operations were concentrated within the walls of factoi'ies, and carried out on an immense scale by the application of enormous capital, had fixed the attention of agriculturists, especially in Scotland, where the very generally sound education of the people had ren- dered them active in the utilization of new ideas. It hence became the leading principle with agriculturists, that in the cultivation of the land the same methods were to be followed as had been so successful in the cotton manufacture ; that small and individual holdings should be concentrated into one vast agricultural establishment ; that human labour should be dis- pensed with as much as possible, and replaced by mechanical power : and the activity of head and hand which accompanied the introduction of this system had certainly the effect of so efficiently improving the modes of cultivation, and increasing the amount of produce, as to have gained almost universal ap- probation for the principles upon which the proceedings of its advocates were based. Yet it is not difficult to trace between the conditions of ma- nufacturing and agricultural industry, differences so essential and so great as to render very doubtful whether any methods can be really common and successful with both. The raw 306 INDUSTRIAL RESOURCES material of a manufacture is subjected to a series of processes which are carried on under the same roof, or at least within a small space, and which occupy but little time. Every thing in the mechanism is constructed for rapidity of work, its superi- ority to human labour consisting not in greater excellence, but in greater velocity of action. The materials are brought to the seat of power, which is fixed, and all its parts being made solid, are little liable to injury, and the cost of the exertion of power is reduced to a minimum. If we compare with this the condition of a farm, we shall find almost entire discrepancy. The operations are not confined to a house, but are spread over, perhaps, several hundred acres. The processes require for their completion many months, from seed time unto harvest, and do not admit of any important interference. The power necessary must be exerted at different times, in different places, and, therefore, cannot be fixed ; it must be locomotive, and as such, the power of animals is cheaper, under the circumstances, than the power of steam. Thus the fundamental conditions of a farm are quite different from those of a factory, and the question of the relative advantages of small or of large farms must be considered on other grounds. This comparison is, however, independent of certain subsi- diary operations of agriculture, which are realh^ mechanical in their nature, and which are more economically accomplished by machinery, such as threshing and winnowing, certain modes of preparing food, &c. ; these are, however, no more agricul- tural than the grinding of corn to meal and flour. They need not be accomplished on the farm. If we suppose a farm of 1000 acres, which requii-es the aid of threshing machines and other instruments for the preparation of its produce, it is evidently the same as if there were a 100 farms of 10 acres, from which the produce was sent to a central point, where a mill and machinery were erected, for the use of which they paid as much as should reasonably remunerate the proprietor. The question, as to whether the large farm or the many small farms should give the greatest amount of benefit in produce and employ- ment, is evidently not thereby aftected. The question is, in fact, one almost incapable of per feet sol u- OF IRELAND. 307 tion, from the very diiferent aspects which it presents in dift'er- ent localities, and under different conditions of proprietorship. But I certainly consider that if there be a final advantage in favour of farming on a great scale, and by all mechanical ad- vantages, it cannot be of any considerable amount. If the ques- tion be put to a farmer of Scotland, or of the north of England, he will answer, decidedly and at once ; invest great capital, throw aside manual labour, and introduce machinery; cultivate several hundred acres : but has this method led to great results in the hands of these very men ? In the mechanical arts we know that the corresponding system has organized anew social power, that colossal fortunes have been on every side created, that large cities have sprung into existence, and employment has been given to the majority of the inhabitants of Great Bri- tain. The wholesale system of agriculture has nothing what- ever of such results to shew ; on the contrary, every day new demands are made for amelioration in its condition. The as- sistance of science is on the one hand invoked, the protection of the legislature is on the other hand demanded ; the agricul- tural labourer is thrown for existence on the woi'khouse, or for employment on the manufacturing town, where, even under existing circumstances, he obtains a rate of wages which the agricultural capitalist cannot afford to pay. Although the general question is thus so difficult to decide, yet if we proceed to the ai^plication of it to the actual state of Ireland, it becomes essentially simplified. Large farm cid- tivation is possible only in countries possessing a thin and scattered population, or else in countries where the existence of extensive manufacturing employment removes the inhabit- ants of the agricultural districts to other places. Thus certain Scotch counties had actually a smaller population in 1841 than in 1831, owing to the migration of the labourers to the manu- facturing districts. In such counties the tendency must be to increase the size of farms, and to introduce, as far as possible, mechanical substitutes for human labour. Also in the north of England, where there is a constant drain of population from the country districts to Newcastle, to Leeds, to Manchester, and Liverpool, it is evident that the tendency being to take X 2 308 INDUSTRIAL RESOURCES the agricultural labourers from their farming occupations, the farmer must endeavour, as best he can, to make himself inde- pendent of them. In Ireland, however, the circumstances are widely different ; a large population is totally dependant on the land for its subsistence. As shewn in page 250, two-thirds of the inhabitants are exclusively devoted to agriculture, and if the agricultural operations of the country, that is to say, the production of food from the soil, and its exportation to feed the inhabitants of another country, be carried on with a sys- tem of cultivation which does not afford employment, the great majority of the people of Ireland must either die of starvation, or be supported in idleness, by a money tax on the earnings of the industrious classes, or finally, be removed from the country, at an expense which, if judiciously applied at home, would enable them to support themselves and families in posi- tive comfort and independence. Voluntary emigration carries off in fact just the class of per- sons whom it is most important to keep at home ; persons of both foresight and enterprize, and possessed of some small capital. The expatriation of the very poorest classes, whe- ther at the public expense or at the cost of individuals de- sirous of removing them, has been found, from the expense, impossible, in any degree sufficient to affect the rate of in- crease of the population. The other alternatives are not likely to meet with approval, either upon moral or on pru- dential grounds, and hence as the great fact, the existence of the people, still remains, the question of what can be done with them must one time or another be fairly met. The only answer is, enable them to support themselves. Give them em- ployment, and as, especially in this country, any manufac- turing system, to be healthy, must be slow in growth, the em- ployment must be agricultural, and I am convinced that such employment may be given, without any injury to the interests of the laud-owner or farmer, nay with a positive amelioration of their condition, provided the proper means be taken to as- certain the true conditions of the problem. Destitute of personal agricultural experience as I have no lesitation to own myself, and consequently feeling competent OF IRELAND. 309 to interpose my own opinion only in such physical and chemical portions of these subjects as stand in immediate connexion with my special pi-ofessional pui-suits, I should not have entered upon this subject, but that I have found the evidence of the most eminent and intelligent persons connected with Irish agricultm'e to agree completely with the views I have ex- pressed. Thus, as to the comparative profit of small and large farms, Mr. Blacker, by whose exertions so much benefit has accrued to Armagh, in his Essay on the Management of landed Property in Ireland, which was honoured with a gold medal by the Royal Dublin Society, says: "Supposing, then, an extensive estate to have recently fallen out of lease (under which circumstances alone such a consolidation as I have re- commended would be at all practicable), and that such a di- vision had been actually made, by which it may very generally happen that two-thirds of the farms will be found not to ex- ceed five to eight acres, it may be asked, how can these tenants live upon such small portions, and still more, how can they pay rent ? I answer without hesitation, they can live com- fortably, and pay as high a rent as any large farmer whatever, if the plan is pursued with them which I have recommended, and have characterized as one in which was involved the hap- piness and comfort of thousands." And again, he remarks in a note: "I am firmly persuaded, that the small farmer who holds his o\m plough or digs his own ground, if he follows a proper rotation of crops and feeds his cattle in the house, can undersell the large farmer, or in other words, can pay a rent Avhich the other cannot afford ; and in this I am confirmed by the opinion of many practical men who have well considered the subject, and I think it will not appear extraordinary, that such should be the case, to any one who reflects that the English farmer of 700 to 800 acres, is a kind of man approach- ing to what is known by the name of a gentleman farmer in this country. He must have his horse to ride, and his gig, and perhaps an overseer to attend to bis labourers ; he cer- tainly cannot superintend himself the labour going on in a farm of 800 acres. Add to this, he must appear himself, and have his family also to appear in a superior rank, and his farm must iO INDUSTRIAL RESOURCES not only enable him to pay his rent, and yield him the support he requires, but it must also be chargeable with the interest of the large cajjital which is necessary to its cultivation ; besides all these drawbacks, which the small farmer knows little ;ibont, there is the great expense of carting out the manure from the homestead to such a great distance, and again carting home the crop. A single horse will consume the produce of more land than would feed a small farmer and his wife, and two children ; and what is more than all, the large farmer says to his labourers go to your work, but when the small farmer has occasion to hire them, he says come; the intelligent reader will, I dare say, understand the difference perfectly. Now if it is really the case that the small farmer has the advantage over the larger, it will be easy accounting for what Mr. Paulet Scroupe observes in his letter to the agriculturists of the west of England, of the Irish farmers being able to undersell the English in their own markets, because the Irish farmers are, generally speaking, small farmers, and the English are large farmers." I am indebted for some numerical statements regarding this question to a gentleman, upon whose judgment I would place the fullest reliance, from his being at once practically ac- quainted with the system of large farms of North Britain, and minutely conversant with the relations of science to agriculture, Mr. Butler of Ballyconra. In answer to some queries which I sent to him upon this head, he says : " In the first place, what number of persons might be taken as deriving steady employment from the labour of such farms through the year, and in each case, besides men, what employ- ment may be afforded to women and children ? In reply, I shall take two farms, one of 200 acres, the other 20 acres, in pre- ference to loo and 10. " FARM OF 200 ACRES. 16 men constantly. 1 boy 12 women about one-half tiie year. 20 men, 3 weeks in Spring.

This, I think, should not be estimated at less than . . . £50 Extra laboTirers, chiefly men, at inter- vals, to the amount of about ... 10 Horse work, 17 £77 " Second. Supposing in each case rent regularly paid, and that in the larger farm the produce be charged with all inte- rest of capital invested, and wear of machinery and horses, and that the sum allocated to the support of the farmer's family, be such as should be derived from any other kind of industry by a man of the same capital and intelligence, should there be any difference in the amount of rent per acre which the large and small farm could pay, and what would you consider that difference to be, and on what side ? " According to a comparative calculation I have made, it % appears to me, that a farm of 20 acres would bear as high a I ^^ rent as a farm of 200 acres, an d such_has bee n my expe- •""^ rience as an _agent in this co untry ; at the same time it is I stoutly asserted in some of the best cultivated districts in \ England and Scotland, the larger the farm the higher the rent it is able to bear, and they have experience on their side. But I do not think that the small farm system ever got a fair trial | there. I dare say that where the landlord builds and keeps up » 312 INDUSTRIAL RESOURCES the tenants' houses it might be cheaper to him to build and keep up one house and steading suitable to a 200 acre farm, than to build and keep up ten cottages, &c., on ten farms of 20 acres each, and it would certainly save him trouble. So perhaps in proportion to the outlay, he might get a higher rent for 200 acres, than he would get from 20 acres. " Thomas Butler." Without proceeding to further quotation on a subject which has already far exceeded the limits originally designed, I shall only remark, that the fact of small farms being able to pay at least as high a rent as large farms appears well-established, and the greater amount of employment that is given is beyond any question. This latter circumstance it will be useful to consider a little further, in connexion with the population and the quantity of cultivatable land in Ireland. In his valuable work on agriculture. Professor Low gives some estimates, from which it results that he considers a 500 acre farm to give an amount of occupation equivalent to the employment of twenty persons throughout the entire year. Now it has been already shewn that the area of land available for cultivation is about 18,000,000 of acres, made up of: Land actually cultivated, 13,464,300 Land capable of cultivation, .... 4,600,000 Now if this be divided into 36,000 farms, of 500 acres, there will be given by their cultivation employment for 720,000 in- dividuals, but as the actual agricultural population amounts to 5,406,743, the difference, or four millions and a half of human beings will be thrown on the world without any means of sub- sistence. They may be considered as forming 850,000 fami- lies, and as it is found that the emigration of a family costs at least £50, the removal of these multitudes, whether paid for by themselves or by the State, should cost the enormous sum of forty-two millions and a half of money. On the other hand, as the total number of existing agricul- tural families is 974,188, it results that from the available land there could be allocated to each a farm of seventeen statute acres. That this quantity i.s sufficient to support a family. OF IRELAND. 313 paying full rent, is a matter of which there is no doubt, and it is thus evident that the finding means of employment for the population is not so difficult, nor requiring such hidden re- sources as is often thought. It does require, however, one condition, at present, unfortunately scarcely obtainable, and on which attention is not yet sufficiently fixed, an amount of general industrial and agricultm-al education, that may enable the landlord to set an example to his tenantry in the disposi- tion to improve the agriculture of his district, and may enable the tenantry to follow that example, and to apply his precepts each to his individual case. The landlord shovdd be, in fact, not merely the proprietor of his peasantry : he should be their preceptor and their friend. That the greater or less magnitude of farms is not in any way necessarily connected with the condition of agriculture, or with any other elements of social comfort of the population, becomes fully evident on reference to the table of the sizes of farms given in page 305. It is there seen that in Connaught the average size of farms is almost exactly the same as in Ulster, and yet these two provinces are the extremes of igno- rance and of intelligence, of activity and of industrial indo- lence, which this island presents. The difference has certainly nothing to do with the smallness of the farms, and that such farms are sufficient, when properly managed, for the support of even more than the average number of individuals in a fa- mily, is shewn by Mr. Blacker, in a passage which disposes so perfectly of the redundant population question, that I shall not again allude to it. In his valuable Essay, Mr. Blacker says : " I cannot conclude without endeavouring to answer one ob- ! jection, which may be made to the opinions I have supported in the foregoing ; I allude to my objecting to the expulsion of small holders for the purpose of consolidating farms, in re- gard to which it may be asked, if this is not done, the popu- lation is increasing so rapidly, that as families grow up, sub- | division must go on, until at length the whole community will/ become paupers ? I mig ht fairly ask in I'c turn, how the plan/ 1 of tui'ning out these families will prevent pgHpcri'swt ? It seemsf 1 , .. \ 314 INDUSTRIAL RESOURCES to me that the latter plan is by much the surest way to pro- duce such a result. But the most satisfactory answer to the question will perhaps be arrived at, bv j^nj^^ tjiaYouHnp^ to nsc er- t.aiu how far the apprehensions of a superabundant population, a t present so generally entertained, may or m ay not be justi- f ied by facts ; for if it should appear there was land enough in the kingdom for all its inhabitants, now existing, and for" as many more as could be anticipated in any reasonable ti me, and t hat nothing more was wanting but p rop er regulations to mak e it avai lable for their wants, t hen the 'objection mav be fai rly considered to be set aside. In a late publication entitled ' Ire- land as it was, is, ana ought to be,' a table is given of the acreable contents and population of each coxmty in Ireland, which may be supposed, at least, so far relatively accurate, as to afford data for the following calculations. From this table t appears t hat the county of Armagh contains 212,755 ac res, an d a population of 220^653 spuls^ a nd that the entire kingdom co ntains 17,190,726 acre s, and 7,839, 4G L> soids; no w, in the county of Armagh, by a recent surve y, more th an one-seventh of the sur face is ialten up by lakes and unprofitable land, and tlie remainder is, for the greater part, but indifferently cu lti- vated, and yet the peasantry are bette r clothed, lodged, a nd fed than they are in most other counties in Ireland^ I cannot, therefore be accused of taking away from the comforts of the rest of the kingdom, by taking the coimty of Armagh as a standard, and its proportion of improfitable surface is not very remote, I believe, from the average of the others ; if, then, 212,755, the number of acres in Armagh, give a po^iulation of 220, G53 souls, 17,190,726 acres, the entire contents of the kingdom, ought to give a population of 17,828,888, in place of 7,839,469, the population at present. It, therefore, appears, t hat supposin g the other parts of Ireland to be as well culti - vated^s Armagh, it would support about two and a half times the n umb er of its present inhabitants, and be able to export provisions largely besides ; for Armagh, notwithstanding i ts population, e xports pork, butt er, and grain in great quantiti es. But before deciding finally upon the population which the kingdom could support, it ought to be examined how far the OF IRELAND. 315 county of Armagh (the standard taken) has arrived at'its full complement ; and in regard to this I would say, ft*om a pretty general knowledge of it, that under an improved system of agricidture, and a regular rotation of crops, t he produce would b e treble of what it yields at present, and I think this may be considered as practicall y pro ved, if I can shew far mers po s- sessing land of average quality, who being induced to change their manner of cultivation in the way already described, are now receiving f u^J treble produce from the iden tical sa me farm to what it formerly yielded ; but supposing it only to jdeld double as much, it would follow, that the population of Armagh, if that jDenc'ficial chaiigo became general, might be doubled also, without in any degree lessening the comforts of the inhabitants ; which increase being taken as the basis of the calculation, and applying it to the whole of Ireland, would make it adeg^uate to the support of better than thirtv-five mi llions of soul s. "When, tln-rei'or.-, it is cuusidcri.'d wluit un- exhausted, I might say unexplored, resourees remain for the maintenance of any incn/asi- of inhabitants that can he ex- pected in any definite period, it must, I think, be evident to every i-etlecting person, that all fears as to a surphi a population are perfectly ideal, and that it is its miequal distrib _ution, an d not its aggregate amount, which is to be deplored." The jirimary object of agriculture, as hitherto discussed, is the production of food, which process necessarily requires the numerous elements essential for animal subsistence, and causes the exhausting action upon the soil which has given occasion to the great diversity of crops, of manures, and of rotations, of which I have endeavoured to explain the principles. There are, however, certain kinds of crops, and those of great prac- tical value, which, when their culture is considered in a proper point of view, become almost free from exhausting action, and as some of these are actually of the highest importance to in- dustry in Ireland, I shall pass to the description of their lead- ing features. I have mentioned as being well established by experienc e, that after the first stage of growth of a plant, the assimila- tion of its carbon is carried on by the decomposition of the at- L 316 INDUSTRIAL RESOURCES mosphere, as may be exemplified in the case of the corn crop and fallow, of which the numerical conditions are given in page 298. The more woody portion of the stem is thus formed almost exclusively from the air and water, as the ligneous fibre, independent of some minutiae of its structure not affect- ing the present question, is composed of carbon united to oxygen and hydrogen in the proportions which form water ; its formula being C,8 H,^ 0,2. This composition of woody fibre, as affecting the cultivation of fibre crops, leads to important agricultural results, which will require full examination. Lig- neous fibre is, however, but one of a class of bodies having the same character. The different varieties of starch and sugar are of precisely similar constitution, all being composed of carbon and of the elements of water ; thus in chemical for- mulae they are expressed by Starch, C,, H,qOjq Crystallizable sugar, Ci^H,, Oj, Grape sugar, C,2 H,2 Ofj None of these bodies contain nitrogen, or, when pure, any inorganic matter. The plants which contain these bodies re- quire for their healthy growth, nitrogen and mineral elements, and consequently exhaust the soil ; but when we take out of a potato its starch, or when we extract from the sugar-cane or beet-root its sugar, the residual portions of the plant contain all the materials that had rendered the plant exhausting, and are capable, if restored to the soil, of acting as a most valua- ble manure, and in fact enabling the land to produce successive crops of starch or sugar without any sensible diminution of its fertility. Of all the starch-bearing plants the potato is that which af- fords the greatest quantity of produce from a given surface of land. The different varieties of potato differ, however, very much, and the following table will indicate exactly the circum- stances of the most important kinds. The plants were grown all on the same quality of land, and the analyses are by Payen, the eminent French agricultural chemist. OF IRELAND. 317 100 PARTS CONTAINED VARIETIBS. 1 CWT.

Thus an acre of large yellow potatoes, which gives but 9^ tons of tubers, produces two tons three cwt. of starch, whilst the acre of Slow Island potatoes, which produce fourteen tons of tubers, give only one ton fifteen cwt. of starch. In cultivating the plant for the purpose of extracting this mate- rial, it is, therefore, of the greatest importance to attend to the existence of these varieties. The preparation of starch from the potato is an operation of very simple kind, and well adapted for the industry of the smaller towns, where potatoes would be usually cheap. It re- quires only the most ordinary skill, and involves Httle ma- chinery, the greatest nicety in it being perfect cleanliness, and care that the washings be well finished and with pure water. The operations of the manufacture are 1st. Washing the tubers. 2nd. Rasping them to a pulp. 3rd. Pressing the pulp. 4th. Washing the rough starch. 5th. Draining and drying the produce. 6th. Bolting and storing. Of these operations it is only necessary to notice one or two in detail. The breaking up of the tubers into a pulp is accomplished by means of cutting cylinders, to which the potatoes are sup- plied from a hopper, nearly as grain is to a mill. The more 318 INDUSTRIAL RESOURCES rapidly the cutters move the finer is the pulp produced, and the more perfect the subsequent extraction of the starch, and hence they generally make 600 to 900 turns in the minute, and as these cylinders are usually about twenty inches in diameter, their periphery moves with a velocity of from 1000 to 1500 yards in a minute. A single cylinder of the above dimensions, and of sixteen inches long, making 800 revolutions in a minute, will reduce to pulp about fifty bushels of potatoes per hour. This for the twelve working hours is about ten tons. The object of pressing or sifting the pulp is to separate the fecula from all foreign substances, especially from the cellular tissue, which, being coarser, rests on the sieve through which the fine starch passes. A great variety of mechanical ar- rangements have been constructed for this purpose, which fulfil their object, but there remains always with the residual pulp 2 or 3 per cent, of the fecula, which it is impossible to obtain. The starch, difi'used in the current of water by which it has been washed out from the pulp, is run into vats, where it is poured off, and fresh water put on : finally the starch is taken out and dried on floors. As it consolidates into very firm masses, it requires finally to be broken down by a kind of bolt- ing machine, before being put up for sale. It is necessary to add some valuation of the money circum- stances of this manufacture. An acre of potatoes, very well manured, and on good land, may be considered to produce nine tons of potatoes, which may be taken as worth £13. From such potatoes it may be expected, that, with proper care, 15 per cent, of pure starch may be extracted, and hence, from the 9 tons, 27 cwt. The market price of the potato starch is variable ; it has been 30.s. per cwt., but it only on rare occa- sions falls below 20s. Taking it at 20s. the value of the pro- duce of the acre becomes £27, leaving for cost of manufacture and profit £12, and of this certainly a large proportion should be profit. I do not think I value the potatoes too low, as, of course, the manufacturer, if not himself the grower, would purchase for store at proper seasons, and avail himself of the lowest terms. OF IRELAND. 319 But this calculation of advantage supposes the starch to be the only valuable matter extracted from the potato, which is far from being the case. The residual pulp, which, when per- fectly dry, amounts to about 5 per cent, of the entire weight of the tubers, has been found a most nourishing food ; in fact, it contains most of the nutritious part of the root, the mere starch which was removed being comparatively much less important in nutrition. This pulp, if moist, putrefies rapidly, it is rich in nitrogen, and in fact analogous to animal substances in com- position, and consequently, if not required for food, would form, by being made with lime and clay into a comijost, a ma- nure of great value, and especially suitable for restoring to the potato ground the substances which the crop in grow- ing had removed. The waters, with which the pulp' is first washed, dissolve a quantity of the soluble constituents of the potato. They rapidly puti-efy, and exhale an odour so rotten as to have rendered the starch factories near Paris a nuisance to the neighbourhood, iintil it was suggested to emjiloy this water as a manure, which has been perfectly successful, and at once removed an important drawback to this branch of in- dustry, and materially increased the fertility of the surround- ing farms. If these residues be properly economized, it is evident that the cost of growing the potatoes may be materially diminished. The atmosphere, in itself, furnishes in fact the cai'bonic acid and water from which the starch is formed, and if the matters taken from the soil in each crop, be returned to it in the resi- dues of the manufacture, the cost of manure, so heavy for this particular plant, may be almost entirely obviated. In this country, where the extensive use and culture of the potato have become almost a national characteristic ; where labour not requiring considerable skill is to be had so cheap ; where potatoes are at their minimum price ; it is not merely to be regretted bvit absolutely disgraceful to ourselves, that we import from Scotland and from France, large quantities of the potato starch to be consumed in Ireland. The starch is not the only material extracted from potatoes, and extensively available in the arts. The potato itself, re- 320 INDUSTRIAL RESOURCES duced to flour, is at present extensively employed upon the Continent in the preparation of a very wholesome quality of bread, and the starch itself is consumed in making confec- tionary, jellies, sago, tapioca, in thickening paper, and in a variety of uses, by which such quantities of it are employed as to render its manufacture a really important and extensive de- partment of industry. The most remarkable of all the appli- cations of potato starch is, however, one to which the excise laws of this country would probably j)resent invincible impe- diments. It is the preparation of sugar and of spirits. Under the influence of certain chemical agents, simple, yet peculiar in their action, and to which it would not be my province here to refer in detail, starch is converted into sugar, and this sugar, by fermentation, yields spirits. On the Continent the manufactui*e of spirit from corn is almost abandoned. Potato spirit is almost universally used ; and in flavour it so resembles brandy that it is well known that a large quantity of the French brandy brought into London, is potato spirit from Ham- burgh coloured with burned sugar. A branch of industry which has acquired considerable deve- lopment upon the Continent of Europe, is that of preparing sugar from the root of the red and yellow beet. The circum- stances of this country do not appear to favour its introduc- tion, Vjut as it is immediately connected with the starch manu- facture already noticed, and that very exaggerated ideas re- garding it are often conceived, I shall briefly notice the general conditions of its preparation. For this purpose the documents recently published, during the inquiry instituted by the French Government, afford satisfactory data. In order to render the results more immediately intelligible, I shall i-educe the weights, values, and measures, from the French to the English standard. The crop of beet roots which is usually obtained in France, varies from ten to sixteen tons per statute acre. The mean produce may be taken at twelve tons. For the cultivation of the acre, it appears that the labour required is, forty-six days of a man's work, and fourteen days of a horse's. The total OF IRELAND. 321 cost of the crop to the farmer appears to be, in average, £7 lis. 6d., made up of Rent and taxes, £2 Manure, 236 Labour, 1 13 Seeds, &c., 120 Pulling and carriage, 13 £7 11 6 The average crop, of twelve tons per acre, stands the farmer, therefore, in 12s. 6d. per ton. A disadvantage of the crop is usually considered to be, that it occupies the ground so long, as often to interfere with the wheat-sowing in autumn. The seed of the beet is placed in the ground as early as it can be considered at all safe from frost, and it continues growing very decidedly to September, and hence the pulling of it is retarded to the latest moment. Now it is, at that season, peculiai'Iy liable to injury from frost, or from wet. A fact discovered by Peligot will, however, if borne out by practical experience, remarkably simplify the cul- tivation. He found that the juice of the young beet root is so much richer in sugar than that of the mature plant, that the total quantity of sugar in the plant may be considered to be the same at all ages, and hence, if tlie roots be pulled up in summer, although the weight of the crop is much less, yet, as the quantity of sugar is not smaller, the market value of the crop is the same. Thus the ground becomes available much earlier, for other agricultural operations, and the plants being pulled in a drier and steadier season, are much less liable to injury from exposure to the weather. The mode of treatment of the roots, in order to prepare the sugar, is not complex. The roots are broken up, by suitable machines, into a soft pulp, and this is submitted to excessive pressure, between folds of cloth, in hydrostatic presses. The juice which flows out is clarified by lime, and evaporated , down, first in ordinary boilers, but subsequently in pans heat- ed by steam, sometimes by evaporation in vacuo, precisely as is adopted for the clarifying and refining of ordinary cane 322 INDUSTRIAL RESOURCES sugar, with which the product, when obtained pure, is identi- cal in properties and composition. The following estimate of the cost of production of the beet- root sugar, in a factory working up thirty-six tons of roots daily, is taken from the summary of the official results given by M. Dumas. The numbers are reduced to the Bi-itish standards, and the price of coal in Ireland substituted for theT French value. The daily expenses of the factory are 36 tons of beet-root, at 16s. 8rf. ... ^30 5^ tons of coals, at 12s 3 6 Bone-black, 360 Lime, 080 Labour, 52 persons, 5 19 Cloths, for pressing, 16 Repairs, lighting, insurance, rent, taxes, and sundries, 6 13 Interest on the capital invested, which is shewn to be, by other estimates, £12,500, 430 Total daily expense, £54 11 The quantity of sugar actually' contained in the beet-root varies from 7 to 10 per cent, in its weight, and, from good materials, and the employment of the best methods, 7 per cent, is available as pure product, after all waste of manufacture ; but the ordinary produce to be calculated on is 5 per cent., which, from the thirty-six tons of beet-root, amounts to thirty- six cwt. of refined sugar, delivered daily from such a factorj% which, on the above outlay, would cost the manufacturer 30s. 4d. per cwt. ; but there are some important deductions to be made from this. It will be recollected, that the sugar is a material which, like starch, contains no nitrogen, and, when pure, no inorganic matters. It hence is formed, during the growth of the plants, by the mere concurrence of air and water, and the other mate- rials of the beet-root, which remain behind after the sugar is extracted, contain the nitrogen and salts which render the beet useful as food, or available as manure if returned to the soil. OF IRELAND. 323 Hence the waste pulp of the sugar works is greedily purchased up by the farmers, and also the skimmings of the boilers, which are found to be a powerful manure, and are sold at a certain price. As it is impossible to obtain all the sugar crystalline, a certain quantity is converted into molasses, or treacle, and this is sold to the distillers for the manufacture of spirits. The ex- penses must, therefore, be credited by the values of these pro- ducts, which are daily as follows : 18 cwt. of pulp, at 6s. 3(/ £5 12 6 12 cwt. of treacle, at Is. 8d 10 6 cwt. of skimmings, at Is 6 £6 18 6 The nett expenditure is, therefore, for each day, £47 12s. 6d. and at 5 per cent, of produce, the sugar costs per cwt. 26s. 6d. or, 2|d. per lb. As by suitable culture and manipulation the produce may be increased to 7 per cent, without any notable increase of outlay, I may add, At 6 per cent, the sugar costs 22s. 2c?. per cwt., or 2^d per tb. At 7 per cent, the sugar costs 19s. per cwt., or 2c?. per tb. It, however, is not to be supposed that the Government would allow of a manufacture, which, although giving exten- sive employment to the population of this country, and opening out a new field for agricultural enterprize, might seriously di- minish the revenue now derived from duties on sugar imported from abroad. Beet-root sugar, if manufactured here, should be, of course, submitted to the same duties as are levied on sugar of colonial origin, and as this amounts to 27s. per cwt., or 3d, per lb, the final cost to the manufacturer, of sugar made in this way, should be therefore so far increased. This may not allow, at present prices, a profit sufficiently large to tempt capital and enterprize into so novel a track. It will be remarked, that the factory estimate supposes the beet-root bought at 16s. 8c?. per ton. It cost the farmer, as shewn above, 12s. 6d. ; he has, therefore, 4s. 2c?. per ton nett profit, or, for the twelve tons, £2 10s. per statute acre. In estimates which I have seen of the beet-root sugar manufac- y2 324 INDUSTRIAL RESOURCES ture, the produce per acre is often taken at twenty or forty tons, as may really be obtained ; but in such case there is little or no sugar ; it has been used in forming the woody matter of the roots, and hence the light crop described above is that finally most productive. In relation to the actual agricultural and manufacturing in- dustry of Ireland, it is still more important to describe the cir- cumstances of those crops which have for their ultimate and valuable product, the vegetable fibre. Of these fibre crops, those of most interest are flax and hemp, especially the former, on which so large a proportion of the population of the north of Ireland may be considered to depend for subsistence. The flax plant, to which I shall first direct attention, may be cultivated on any soil of moderate fertility, but, of course, will grow in greatest luxuriance, and yield its largest produce, where the land is most fertile. It is, however, indispensable, that the soil be rendered thoroughly open, and perfectly clean. The order of rotation with other crops varies in different coun- tries, but on the Continent, as in Belgium, where its cultiva- tion is best understood, the ordinary custom is, to bring it in after a corn crop, and not to introduce it into the course more frequently than once in seven years. The flax is a very ex- hausting crop, and hence requires abundance of manure, which is supplied to it in Belgium, in the most effective form, as liquid manure. It will be shewn, immediately, that the flax contains but little lime, the presence of which, in a caustic form, in the soil, appears to be injurious to the plant, hence it is proper, whore lime has been necessary to the soil, to inter- mit the culture of flax for a certain season. The composition of the soil on which the cultivation of flax may best be carried on, being a problem of the highest practi- cal interest to this country, the Flax Improvement Society of Ireland, in pursuance of their laudable objects in promoting this branch of industry, commissioned me to make analyses of some soils which iiad produced remarkably good crops of flax. The soils were all light clay loams, and afforded th(! following results, which I extract from the Report of the Society. OF IRELAND. 325 No. 1. No. 2. No. 3. Silica and silicious sand, . . 73-72 69-41 64-93 Oxide of iron, 5-51 5^29 5^64 Alumina, 6-65 5-70 8^97 Phosphate of iron •06 -23 •81 Carbonate of lime, .... 1-09 •53 1^67 Magnesia and alkalies, with traces of sulphuric and mu- riatic acids, •32 •25 •45 Organic matters, .... 4-86 6^67 9-41 Water, 7-57 ir48 8-73 99-78 99^58 100-11 The organic matter in these soils was rich in nitrogen ; their fertility is, therefore, from the analyses, easily understood. A point which may be noticed in relation to the growth of flax is, that its quality is essentially improved by thick sowing. This arises, not from there being more flax grown, but from the closeness of the plants forcing them to grow upwards with a single stem to gain access to the air, and thus to prevent their branching, by which the fibre is shortened, and rendered irregular. Every thing in the cultivation of this plant is sub- servient to the formation of a long and delicate woody fibre, and it is owing to this fact in the practical history of the flax, that certain sources of economy in its agriculture, which I shall point out, become practicable. The ligneous or woody fibre, which finally is converted into the linen thread, is composed of the same elements as starch and sugar, and in nearly the same proportions. Omitting cer- tain minute diff'erences between the true fibre and the matter which occupies its cells, its composition may be expressed by the formula C,gH,2 Ojj and, when pure, it contains no inor- ganic matter. Its elements are, in 100 parts : Carbon 50-00 Hydrogen, 5-55 Oxygen, 44-45 326 INDUSTRIAL RESOURCES Hence this fibre, which constitutes the entire money value of the flax crop, is produced during the life of the plant, by the elements of the atmosphere, and the materials taken from the manure and from the soil are, in reality, employed by the plant in organizing substances which do not make any return to the farmer, but which are, on the contrary, under certain circumstances, considered to be positively a disadvantage. It is, therefore, of importance, that it should be understood, that by a proper system, the growth of flax and similar fibre crops should be destitute of all exhausting influence. That the ma- terials drawn from the soil by such a crop should be foimd in the waste products of its manufacture, and should be available by being returned to the soil, to restore it to its original con- dition of fertility. In order to render this principle fully intel- ligible, I shall enter into some detail regarding the processes to which the flax is subjected, and the nature of the products obtained from it. The flax, when it has grown to suitable maturity, according as the design is to allow it to ripen its seed or not, is pulled, and either immediately, or in the next spare season, according to the circumstances of the locality, it is subjected to the process termed rotting or watering. In the stem of the flax there may be recognized three structures, the outer skin or epidermis, covering a close network of fibres which encloses the plant as in a sheath, and in the centre a stem of dense pithy material. The fibrous network is connected together by a glutinous matter, which must be decomposed before the fibres can be separated from the stem, and it is to soften and rot this substance that the plant is steeped. If the steeping be con- tinued too long, the fibre itself may rot, and be weakened and injured in quality ; if the stooping be not continued long enough, the fibres are not thoroughly separated from each other, and the quality of the flax is coarser than it might be. The gene- ral tendency is not to rot the flax enough, but it is a process requiring very careful management and attention, to conduct it with the greatest advantage. In order to ascertain what occurs dm-ing the steeping of the flax I instituted chemical examinations of the substances and OF IRELAND, 327 process. I have already given the composition of the pm-e ligneous fibre, and in the following tables are shewn the results of my analyses of the composition of the flax stem as it grows, and of the ashes which it yields. These are in fact its organic and its inorganic elements. The composition of the ash varies very sensibly vsdth that of the soil upon which the plant is grown, but it is not necessary to introduce that consideration for the present object. FLAX PLANT.

This arises from the solution of the gluti- nous material which had cemented together the pure fibres. To examine this material, I employed it as it is produced when the steeping water is dried down, and the following tables shew its organic composition, and the composition of the ashes which it yields. I term this substance, for brevity sake, flax-steep extract. 328 INDUSTRIAL RESOURCES FLAX- FLAy-STKKI' EXTRACT STEEP EXTRACT. WITHOUT ASUKS. Carbon, 30-69 52-93 Hydrogen, 4-24 7*31 Nitrogen, 2-24 3-86 Oxygen, 20-82 35 90 Ashes, 42-01 100-00 10000 It is thus seen, that the steep-water dissolves out a great quantity of nitrogen, and of the inorganic materials of the stem; in fact, that it removes from the plant almost every thing that the plant removes from the soil. This is confirmed by looking to the composition of its ashes, which are shewn by the following analytical results. There are foimd 42 parts of ashes, in every 100 parts of flax-steep extract, consisting of Chloride of potassium, 3-8 Sulphate of potash, 4-4 Carbonate of potash 3-8 Carbonate of soda, 13-2 Silica, 5-5 Phosphate of iron and alumina, .... 3-2 Phosphate of linie 21 Carbonate of lime, 4-0 Carbonate of magnesia, 2-0 Total quantity, 42 per cent. The steep-water thus dissolves, especially, the alcaline in- gredients, and the phosphates of the plant, and hence leaves the rotted stems in a condition of almost pure ligneous matter. The stems of the plant, after having been thus steeped, un- dergo a rough bleaching and drying, by being t/rassed for some days. They are then broken by the hackle, and finally, the fibre separated from the residual woody pith or chaff, by the operation of scutching. These operations may be carried on either by hand or by machinery, and the relative value of the systems may hereafter rc^quire attention. The fibre, after these processes, is sent to market; it passes into tlie hands of the •i OF IRELAND. 329 linen manufactiu'ers, and becomes the element of mechanical industry, such as has been treated of in the earlier chapters of this work. Now the agriculturist should steadily bear in mind, that the fibre which he sells to the flax spinner has taken nothing from the soil : all that the crop took out of the soil he has still in the steep- water, and in the chaff of the scutched flax, and if, after suitable decomposition, these be returned to the land, the fertility of the latter will be I'estored, and thus materials, at present utterly neglected, and even a source of inconve- nience, may be converted into most valuable manure. That the water in which flax has been steeped possesses powerful influence as a manure, has been observed by various persons ; thus round the edges of bog holes used for steeping, a luxuriant and tender herbage often arises in vivid contrast to the surrounding barren peat. Various agricultural authori- ties have noticed its beneficial effects when experimentally used, but I shall only quote, in order to shew the attention it deserves, the following notice by Mr. Wakefield- " The water in Avhich flax has been immersed is, in Ireland, entirely ne- glected, but Mr. Billingsby mentions it as an excellent manure, and no country in the world, perhaps, aff'ords better opportuni- ties of employing it than Ireland. I made frequent inquiries about it, but could never hear of a single instance of its being used. The author of the Sm'vey of Somersetshire (Mr. Bil- lingsby) says : ' it is observable, that land on which rotted flax is spread to prepare it for heckling, is greatly improved thereby, and if it be spread on a coarse sour pasture, the her- bage will be totally changed, and the best sorts of grasses will make their appearance. Having myself cultivated flax on a large scale, and observing the almost instantaneous effect pro- duced by the water in which the flax was immersed, I was in- duced, some years ago, to apply it to some pasture land, by means of watering carts similar to those used near London for watering the roads. The effect was astonishing, and advanced the land in value ten shillings per acre.' " The chaff remaining after the scutching might also be formed into manure, and has actually boon found of as much 330 INDUSTRIAL RESOURCES value as its composition would indicate. Thus, in fact, the farmer sending to marlvct only the fibre of the flax, which de- rives notliing from the soil, has the opiJortunity of economiz- ing in other and highly remunerating modes all the residual materials. This chaff was found to consist of Carbon, 50-34 Hydrogen, 6-33 Nitrogen, '24 Oxygen, 41*32 Ashes, 157 10000 Its nutritive quality cannot be material, but mixed wth the water of the flax-steep, it should complete the restoration to the soil of the constituents of the growing flax. The average produce of scutched flax, as given by Wake- field, reduced to the statute acre, is 5431b from nineteen gal- lons of seed. This is thirty-four stones of sixteen poimds. The usual produce of Scotland is stated by Low, to be forty stones, and at present by the Reports of the Flax Improve- ment Society, the produce in the north of Ireland may be taken as averaging forty-two stones. The weight of the flax- straw, when quite dry, may be taken as approximating to about two tons. IVIr. Crosthwaite, whose intimate acquaintance with all branches of this industry renders his authority highly valua- ble, considers that there are about 100,000 acres imder flax in Ireland, and that the produce is about 30,000 tons, of an ave- rage value of £50 per ton. This is 6s. 3d, per stone, and should give about £12 10s. for the usual produce of the statute acre. The quantity of flax grown appears to be on the increase, and its quality also to be improving, as by the Report of the Flax Society it appears, that the amount of the crop in 1841 was 25,000 tons, averaging £45 per ton, whilst in 1843 it was 36,465 tons, and the average value was considered to be at OF IRELAND. 331 least £55. This increase of value being, if not wholly, cer- tainly in great part, attributable to the exertions of that very useful Society. The value of the flax crop depends in a very material degree, indeed it might be said entii'ely, on the care taken in the pre- paration of the fibre. The value which it may assume under careful management, and the final amount of employment which it gives, is shewn by the following fact : ' ' Mr. William Blakely, a tenant of the Dean of Dromore, on the townland of Corcelany, near Waringstown, grew, last season, three statute acres (about 1a. 3r. 16p., Irish measure) of flax, which he managed strictly according to the directions of the ' Society for the Promotion and Improvement of the Growth of Flax in Ireland.' The produce of this field has been recently purchased for 15s. per stone, by Messrs. M'Murray, and Hen- ing, of Waringstown, the eminent cambric manufacturers, who say, it is equal, if not superior, to ant/ fax they ever saw before, and that they have given 36s. per stone for foreign flax, of an inferior quality. " A large portion of this flax has been delivered to Messrs. M'Murray and Co. ; but some still remains to be dressed by the celebrated machinery of Mr. Henry, of Keady. Should this part be as productive as that already furnished, the entire produce of the three acres will be 120 stones; which, at 15s., will give to the farmer £90 ; but he has a certainty of 100 stones, which will realize him £75. " This flax is now in process of conversion into cambric pocket-handkerchiefs; it is capable of being spun to thirty hanks to the pound, and is to be spun by hand. Mark, now, the em- ployment this will give. "It will give constant employment, for twelve months, to 1 58 women to spin it ; eighteen weavers will be occupied a like period in weaving ; and it will employ forty women for a year to hemstitch (or vein) the handkerchiefs, thus giving constant employment, for twelve months, to 210 persons. "It is cu' 'ous to trace the result of the process which this flax is now imdergoing: — It will produce 210 webs of cambric, each web containing five dozen handkerchiefs ; each dozen 332 INDUSTRIAL RESOURCES will be worth 50j.-., and the entire, when finished, will be wortli £2,600." " If arguments in favour of the Flax Imjjrovement Society were needed, the case specified in the above letter would fui*- nish them. The farmer alluded to was induced to try what he could do in the way of growing flax, by reading a small tract issued by this Society, which accidentally fell into his hands. The land on which he sowed the seed was the most barren part of his farm." Where so much depends on the mechanical and chemical treatment of the plant after the crop has been pulled, it is easily conceivable that under the ordinary circumstances of the Irish farmers, it is difficult to carry out the preparation of the fibre, so as to give it the best quality, and in fact in Bel- gium and Holland, where the flax cultivation and manufacture are in their most advanced state, the growth of the plant and the fabrication of the fibre are totally distinct occupations. The crop is purchased by a factor, who takes the dressing into his own hands, and, being devoted to that one department, is acquainted with all mechanical arrangements and details ne- cessary to success, and it frequently happens that the farmer actually obtains for the crop, as grown, more money than he should have obtained for the imperfectly dressed produce of it, and is spared the loss of time, of labour, and interference with other business, which, retaining the mechanical treatment of the flax in his own hands should necessarily entail upon him. In the present state of industry, I conceive the general adoption of the system of factors as indispensable to progress. With- out improvement in quality of product, the manufacture can- not extend, and without the preparation of the fibre being taken up, and cultivated as a distinct profession, no important amelioration in it can be expected. From the importance of the flax culture, as well to the far- mer as to the manufacturer, it might be supposed that it should be at least cultivated to such an extent, as to supply our own industrial wants. Such, however, is far from being the case ; every year a largo quantity of flax is imported into Great Britain and into Ireland from the Baltic ports, and from OF lEELAND. 333 Belgium ; the total quantities for three late years are shewn in the following table : FROM WHENCE IMPORTED. 1840. TONS. 1841. TONS. 1842. TONS. Russia, Prussia, Germany, Holland, Belgium, France, Other countries, . . . Total tons, . . . 43,520 6,779 405 5,650 4,032 2,164 99 48,472 5,533 519 6,024 4,865 1,477 478 40,720 5.624 815 4,828 2,475 866 385 62,649 67,368 55,713 It is worth observing, that the diminished importation of 12,000 tons of 1842, is almost exactly the quantity by which, owing to the exertions of the Flax Improvement Society, the home crof) had been increased at the same period. The agricultural employment which the flax crop gives, may be estimated from a statement by Mr. Blacker, whose ability as a judge is so well known; he says: "After the most mi- nute calculation by practical men engaged in the growth of flax, the labour necessary for every acre of flax is computed to be seven days of a man, fifty-four days of a woman, and four and a quarter days of a horse. Now 55,610 tons weight [which was the import in 1833, when Mr. Blacker wrote], supposing each statute acre to produce four cwt., which is a full average crop, would be the produce of 278,050 acres, which, according to the above estimate, would require in labour equal to the employment of 6,488 men for 300 days in the year, 50,015 women for the same number of days, and 3,939 horses for ditto." It appears thus, that thei-e is twice as much flax imported into Great Britain from foreign ports, as there is grown in this country, and yet there is no actual impediment to its cul- tivation, for it appears to be uniformly a remunerating crop, where attended to with ordinary care, and may, by the proper application of scientific principles to its culture, be rendered 334 INDUSTRIAL RESOURCES one of the least expensive or exhausting crops tliat the agri- culturist can have to do with. There is finally to be noticed, in relation to the secondary advantages of the flax crop, the utilization of the seed, either as food or for sowing. It appears now well established, that the fibre is not injured by allowing the plant to form the seed, and that the seed may be saved in good condition imder the ordinary circumstances of our climate. This is a very impor- tant addition to the value of the crop : the seed being employed for preparing oil : the residual linseed cake being a very va- luable food for cattle, or for manure ; or the imripened seed in the capsules, or bowes, as they are termed, may be at once given to cattle. The husks of the seedvessels have been used as food for cattle in the north of Ireland, and by the testimony of Mr. Nevin, and of Mr. Charley, with remarkable advan- tage. In fact, it would appear that there is no part of this very remarkable plant that is not directly or indirectly capable of being applied to useful purposes. The great value of it to this country is, however, that its cultivation supplies not merely a source of agricultural, but also of manufactiu'ing employment. In this respect, it is far more beneficial than a food crop of the same money value, or occupying the same ground. The flax, as it leaves the hand of the farmer, gives a livelihood to the dresser, from him it passes to the spinner, to the weaver, the bleacher, and perhaps to the embroiderer, according to its destination. JNIr. Andrews illustrates the actual profit and em2)loyment given by the crop described page 33, in a calculation which, after coi'rcction of a few typographical errors, stands thus : " 100 stones at 13s. — £75; each stone calculated to produce 5^1b. of dressed flax — in all 550ib. — spun to 30 hanks to the lb, will produce 16,500 hanks. About 158 females will be em- ployed twelve months in spinning, at the rate of two hanks jjcr week (six working days) ; wages for spinning each hank, about Is. 8^., or nearly 'id. per diem for each spinner. This quan- tity of yarn would make 210 webs of cambric pocket-hand- kerchiefs, each web containing five dozen. About 18 weavers Avould be twelve months weaving this quantity, allowing each OF IRELAND. 335 man a month for each web (17i weavers exactly) ; wages per web, £2 : or from 9s. 6d. to 10s. per man per week. About 40 females would be employed twelve months in needlework (hemstitch or veining) ; each could do one handkerchief on each working day; wages, 8s. per dozen, or 8c?. per day. The goods, when finished, would be worth £2 10s. per dozen. " 158 spinners 12 months, or 52 weeks, at about 3s. 4d. per week, . . . £1,369 6 8 18 weavers 12 months, at £24 per annum, 432 40 needlewomen 52 weeks, at 4s. each per week, 416 216 persons employed.

While thus recog- nizing the benefits which are likely to accrue to Irish indus- try from this modern institution, it is important not to forget how much we owe to others. The Royal Dublin Society, almost immediately on its foundation, applied itself anxiously to pro- mote the culture of flax, and to improve the methods of its preparation. They obtained the assistance of persons well experienced in the Belgian processes, and so early as 1739 published a volvune of papers, principally occupied with direc- tions for the growth and treatment of flax, and which contained, intelligibly laid do\ATi, almost every detail of the processes now being introduced as the newest and most advantageous. Owing to the disastrous social condition of the country, which 336 INDUSTRIAL RESOURCES has SO kept it back in every branch of peaceful enterprize, the beneficent intentions of the Royal Dublin Society were not carried out, but now that with renewed energy, it labours to awaken Irish industry, that it possesses in numerous junior societies, so many active co-operators, and that the people, by education and steadiness of habits, are become more fitted for the pursuits of peaceful industry, it is to be hoped that the seed shall no longer be scattered upon an unfruitful soil, but spring forth with a sound and vigorous vegetation, which may bring peace, abundance, and contentment to the land. It only remains to indicate, in a general manner, the extent to which the mechanical manufacture of flax is prosecuted in this country. In the work on Ireland, published by Mr. and Mrs. Hall, some statistical results are given, which they ob- tained by personal inquiry in Belfast, and which, though pro- bably above the truth, are not more exaggerated than is usual with such general estimates. They consider that there are in Belfast, now at work, 155,000 spindles, consuming 210 tons of flax per week, and that there are employed in the manufacture of flax, 170,000 hands. They estimate the total number of per- sons supported by the linen trade as not less than half a mil- lion : that the annual value of the linen cloth manufactured in Ulster is not less than £4,000,000 : the capital involved in its production not less than £5,000,000, and that the annual amount of wages paid to those engaged in the manufacture amounts to £1,200,000. This sum, for the 170,000 above mentioned, would make the average wages to be only 2s. 9d. per week. The extent of this manufacture stands in such relief from the usual absence of all manufacturing industry in Ireland, that we frequently attach to it a degree of importance and an idea of absolute magnitude that it does not really possess. Thus we often hear the linen manufacture spoken of as being the staple of this country, whilst wool and cotton are in return the natural manufactures of the sister kingdom. In reality, how- ever, Ireland is almost as much behind in this as in every other branch of industry. The town of Diuulee alone is considered to manufacture as much linen as all Ireland, and the relation OP IRELAND. 337 which the manufacture of flax bears in the three kingdoms, is exactly shewn in the following table, which is extracted from the Report of the Factory Inspectors for 1839, since which period no sensible alteration has taken place. In England there were 169 mills, worked by 4,200 horse power, and employing 16,573 persons. In Scotland 183 mills, worked by 4,845 horse power, and employing 17,897 persons. In Ireland forty mills, worked by 1,980 horse power, and employing 9,017 persons. It is difficult to reconcile this official return with the estimate of Mr. Hall, just before quoted ; as the proportion of home-spun and woven linen goods can scarcely be so considerable as to accoimt for the discrepancy. Finally, the following extracts from official tables will shew, as far as documents allow, the actual, or, at least, recent, extent of the export trade in linen products.

It is needless for me to point out how strenu- ously our efforts should be directed to the extension of a branch of industry, which, in its various departments, affords, from a given surface of land, employment to a greater number, and a greater variety of individuals, than any other branch of human occupation. The agriculturist, the mechanist, and the chemist, are all equally occupied with its preparation ; and, certainly, the natm'al circumstances of the country are such as to adapt it, in a singularly perfect manner, for the development of the flax and linen manufacture, to an indefinite extent. The linen manufacture has been, hitherto, almost exclu- sively confined to the north of Ireland. This does not ai'ise from any physical circumstances of soil or climate, or from the greater facilities of access to mechanical power ; on the con- trary, the soil of Ulster, if we except the valley of the Lagan, and some scattered districts, is not, by any means, equal to the soils of the south and centre. The growth of this depart- ment of industry in Ulster, is owing rather to moral causes. Its population was, essentially, of a class devoted to industrial pursuits, and eager after the independence and power which pecimiary success confers, and which was within their reach ; whilst in the south, the wretched remnants of feudal barbarism paralysed all tendency to improve. The lord was above in- dustry ; the slave was below it ; and hence, although the cir- cumstances of a fertile soil, easy access to markets, and abun- dance of motive power, wore, in themselves, favourable, the blessings which nature presented were loft unutilized, by the ignorance and inertness of the people. OP IRELAND. 339 In fact, if we consider the situation of tliose countries in which the manufacture of linen and other flax products has become the charactex*istic fact of their industrial history, we shall find the soil and geographical condition quite different from those of the north of Ireland. In Egypt, whose dignitaries were clothed in purple and fine linen, and from which the cul- ture of flax has spread over the civilized world, the soil was formed by the mud carried down in the overflowings of the Nile, and spread over the surface of the lower coiui try along its banks. The soils of Belgium and Holland, the countries now most remarkable for the excellence and abundance of their flax in- dustry, have been produced by the acciunidated mud deposited by the vast rivers, which, draining the greater part of Europe, discharge their waters into the German Ocean, by numerous channels. The rivers which flow into the Baltic afford, also, on the low grounds along their banks, the seats of the flax agriculture of Russia, and Northern Prussia ; and, guided by these analogies, may we not ask, where are the similar soils, or districts, in our own country ? They are abundant, and available along the line of the principal river. The lands hitherto liable to flood, by the irregular risings of the Shannon, but, by the improvement of its channel, about to be permanently rendered available to agriculture, amount to not less than 32,500 acres above Limerick, whilst below that city, the cau- casses, or marshy grounds, of the extraordinary fertility men- tioned by Wakefield, are to be foimd. Such soils afford the most complete parallel to those districts of Egypt and of Bel- gium, which have been for ages the seats of the growth of flax. The water power at Killaloe, fully described at page 83, places at the hands of the manufactm-er, the means of every mechanical preparation of the crop. The river furnishes for 200 miles the most convenient access to domestic markets, and the port places him under equally favourable circumstances for the foreign trade. So remarkable a combination of facilities for industrial success is rarely to be met with. The flax had formerly been actually cultivated to some extent in certain parts of the south and centre of Ireland, and the quantity of produce obtained was found decidedly greater z 2 340 INDUSTRIAL RESOURCES than the average of the crops given in the north of Ireland. I am informed by experienced persons, also, that the quality of the fibre was of a delicacy but seldom met with in the ordinary flax of Ulster. Neither the cultivation nor the manufacture was adopted by the people with the energy and patience which alone can lead to success. The encouragement to industry was unhappily associated with other objects, which deprived it of all power of really bettering the condition of the people ; which interposed between those who might have served as efficient teachers, and those who were to derive instruction, a barrier which, it is to be hoped, the experience of centuries has at last shewn cannot be removed by measures of cruelty or menace. Connected with the cultivation of flax, as a department of agriculture, and of subsequent mechanical industry, is that of hemp, which, in all its states, indeed, bears an almost perfect analogy to the growth and preparation of flax. During the war, when access to the Baltic, from whence the great supply of hemp is drawn, was difficult, this plant was cultivated in this country with some success. The crop appears to require a good soil, and in its preparation a degree of care, which the general run of farmers were not capable of applying to it, and hence, since that period, the attention of agriculturists having been exclusively fixed on corn and other food crops, its culti- vation has been totally abandoned. The constitution of the hemp plant is almost exactly like that of flax. It is pulled, with suitable care, in regard to the ripening of the seed, which its dioecious structure requires. The plants are steeped, until the gummy material which connects the fibres is softened, and rotted ofi", and then, after drying, and a certain amount of bleaching on green land, the fibrous skin is peeled from the stems, and the fibre obtained clean by scutch- ing with appropriate instruments. The hemp fibre, like the flax fibre, consists of purely woody matter, having the chemical composition of C, J H, J 0|2, and contains neither nitrogen nor saline matters. It is hence formed in the plant by the agency of the atmosphere alone, and the materials which the plant extracts from the soil, or from the manure used in its cultiva- OF IRELAND. 341 tion, are found, not in the fibre, but in the waste of the pro- cesses of its preparation. The water in which it had been steeped, the chaff which remains when the fibre is cleaned off, contain various substances, which, when properly returned to the soil, give it back all that the plant in growing had removed from it, and hence would restore its original condition of fer- tility. In this way the hemp may, like flax, be rendered one of the least exhausting crops, and the profit on its cultivation in- creased, of course, in the same proportion. In order to establish these principles by chemical analyses, I instituted an examination of the hemp plant and its products, analogous to that which has been already noticed regarding flax. The following were the results. The hemp plant con- sists of: THE STEM. THE LEAVES. Carbon, 39-94 40-50 Hydrogen, 5-06 5-98 Oxygen, 48-72 29-70 Nitrogen, 1-74 1-82 Ashes, 4-54 22-00 100-00 10000 The ashes of the plant (stem and leaves), consisted of Potash, 7-48 Soda, -72 Lime, 42-05 Magnesia, 4-88 Alxuuina and oxide of iron, -37 Silica, 6-75 Phosphoric acid, 3-22 Sulphuric acid, 1-10 Chlorine, 1-53 Carbonic acid, 81-90 100-00 When the hemp is steeped, the wat«r acquires very strongly narcotic properties and a disagreeable odour. On drying it down a brown extract is obtained, which was composed of 342 INDUSTRIAL RESOURCES Carbon, 28.28 or 55-66 Hydrogen, 4-16 ,, 8-21 Nitrogen 3-28 ,, 6-45 Oxygen, 15-08 „ 29-68 Ashes, 49-20 Without the ashes. 100-00 100-00 This material contains so large a quantity of nitrogen, as well as of saline matters, as to shew that when it had decom- posed it should become a most valuable fertilizer. The steeped hemp stem, as it remains after pulling off the loose tibrous coat, is little more than ordinary wood. It con- tained Carbon, 56-80 Hydrogen, 6*48 Nitrogen 0-43 Oxygen, 34*52 Ashes, 1'77 100-00 The cultivation of the hemp is not likely to be in future as important as hitherto it has been. The substitution of iron for hemp in the standing rigging of ships, and the introduction of coarse Egyptian flax in the manufacture of various fabrics where previously hemp had been used, will probably limit very much its consumption. It is only from its close analogy to the flax, and the identity of principle by which so much economy may, as I believe, be introduced into the cultivation of both, that I have here noticed it, even thus briefly. I have endeavoured, in the foregoing observations, to notice briefly the questions regarding Irish agriculture, which ap- peared to me most intimately connected with its position as an important branch of industry. It has been shewn that the amelioration of the processes of cultivation requires a very ex- tended knowledge of chemical and mechanical science. That husbandry as an art, so far from presenting the monotonous and almost passive routine in which rustic existence has been dreamed away, requires to be placed parallel with the other OF IRELAND. 343 great departments of human occupation, in the amoxmt of in- telligence which its successful practice calls into play. Until, by suitable education, the minds of the agricultural population of all classes are awakened to a knowledge of what their art really depends upon, all secondary exertions for its improvement must be completely futile. There exist in Ireland millions of acres of land perfectly well adapted for cultivation, but which have never yet supplied a morsel of food for man. It is weU established that on the lands actually cultivated there might be raised three times the amount of food that is now produced, were a suitably improved system of agriculture brought into general use. And yet there exists in Ireland a population, starving and xmemployed, wearing out a miserable existence on the charity of those only a degree less wretched than themselves, or sup- ported by a tax levied on the industry of the more energetic and more instructed classes. Were the true conditions of agricultural success generally imderstood such could not be the case. The cultivation of these wastes, which, as evidence of the most decisive and practical character has shewn, can be easily and economically reclaimed, would give remimerative occupation to hordes of those who now are among the weightiest burthens of the land. The productiveness of the soil being augmented by proper drainage and deep working, and the pastoral system replaced by the turnip and green crop husbandry, by which so much more food is raised and so much more employment given, it would be found that, so far from the existmg numbers of the people being too great to be supported by the soil, the new conditions of agricultm'al activity would provide means of pro- fitable occupation for a much greater number than that pro- portion of om- population, which can, even now, be considered as dependent on it for the means of life. 344 INDUSTRIAL RESOURCES CHAPTER IX.

NOTICE OF THE QUESTION OF GO- VERNMENTAL CONTROL IN THE CONSTRUCTION AND MANAGE- MENT OF RAILWAYS. It is not enough that a country may possess, in the fertility of its soil, or the richness of its mines, the materials for the creation of industrial wealth, but also there must be the means of bringing these resources into play by land and water com- munication. By their aid the different substances necessary OF IRELAND. 345 to manufactures are brought to the localities where the pro- cesses to which they are to be subjected can be carried on with most advantage, and the produce be conveyed to the situations where its sale may be effected with most profit to the owners. Direct and safe modes of communication are, therefore, indis- pensable to the development of industrial pui'suits, as well for the procuring access to raw materials, as to secure markets for the manufactured goods. It is, however, not wonderful that, industry having received so little extension imtil a few years back, the means of communication should still remain in Ireland comparatively undeveloped. The internal communications of a country demand attention, however, on grounds of far higher order than their merely fa- cilitating mercantile transactions ; they are connected with the highest moral aims of the legislator, by their influence on the habits and the conduct of the people. The isolation in which man is condemned to live, in a district destitute of roads, or where transport is difficult and expensive, is fatal to his pro- gress in civilization and humanity. He grows up in ignorance of his feUow-men ; his mind, limited to the circle of a few ideas elsewhere obsolete, looks upon all deviation from them as fraught with injury and ruin. The results of new methods in the management of land or labour, which within a few miles are actually producing the greatest benefits, remain utterly unknown to him. The stimulus of contact with persons above him, and yet not too far removed from his own sphere to pre- vent the ambition arising within him of exerting himself to attain the comfort and consideration which they enjoy, does not present itself to his mind. His isolation and his ignorance remove him equally from the instructor, and the instructor from him, and he resists with violence, by which, in the ab- sence of reasoning, he can alone shew his will, the intrusion of all novelties calculated to break through the miserable mo- notony in which his forefathers and himself have vegetated. An enlightened French minister, in speaking of the cost of the manufacture of iron in France, as affecting railroads, said : "The question of the price of iron, — it is the question of roads, the question of communications, of intercourse between man INDUSTRIAL RESOURCES man, of the obliteration of prejudices, of the production of tual amity, of morality, and civilization." /These considerations are borne out in a very remarkable nfanner by the results of the construction of roads in certain parts of Ireland, that had been previously destitute of the means of transport. The consequence of not having roads is illustrated by the evidence of Mr. Fetherstone, who, describ- ing some of his important bog improvements to a Committee of the House of Commons, says : ' ' The oats these lands grow is so very fine, and of such a rich gold colour, that if we can pos- sibly get it down to the lowlands, we sell it freely for seed oats, but the roads being so bad, we i>ut it to the purpose of illicit distillation. It is a great deal cheaper to distil it than to bring it to market, for we could only bring a sack at a time, and we distil it on the spot at once, and on that accovmt very little of it finds its way to the market." . . . "There are no roads at all. I was obliged to take my carts to pieces and carry them on horses' backs, and then I made the roads through my part of the mountain. The mountain is alluvial laud, and produces anything. The oats are beautiful, and an enormous crop ; but what is the good of it ? you cannot send it to mar- ket. There are no gentlemen residing in that mountain coim- try, and the people are in a lawless state." The combination of facts is here important. A fertile soil, its produce available only by outraging the laws, demoralizing the people, and ren- dering them fit for the perpetration of those insane outrages, which we too often have to record. For this the remedy is not Draconic legislation, but making roads ; not blindly punishing the people for being savage, but opening to them the means of civilization and honest industry. When this is done, it is remarkable how instantly the very poorest of the people hasten to avail themselves of its benefits. When Mr. Nimrao was engaged in the construction of the Con- namara roads, his workmen were actually inconvenienced by the country cars conveying produce and objects of traffic, even up to the spot which the engineers were at the moment com- mencing to render passable. Similar instances occurred else- where. In the district called Pobble O'Keefe's country, on the OF IRELAND. 347 limits of the counties of Cork, Limerick, and Kerry, which had been a place of refuge for malefactors and desperadoes of all kinds, and had remained totally uncultivated, a set of roads were made under the direction of Mr. Griffith. As the roads advanced, cottages and farm houses sprang into existence along their sides ; cultivation extended itself from their edges into the waste. The bad characters that had inhabited it dis- appeared, and a single policeman has marched a prisoner through the entire district, without any other than the most friendly greetings along his way. The whole organization of the locality has been changed, and at the same time with a pecuniary benefit to the public funds, which I shall hereafter notice. The effects of opening out with roads some very desolate parts of Clare, are thus described by a gentleman of intelli- gence and station, in a communication to the Board of Works, the accuracy of which the Commissioners guarantee. * ' Communications have been effected between large towns through mountain districts, whereby the distance will be m each case shortened, and in which districts, previous to the construction of these roads, no wheel carriages of any kind could be used. ' ' The immediate effect has been to excite the minds of the people to the pursuits of honest industry ; they can now bring lime into the mountains, and they can carry produce out of them. "Illicit distillation has been checked, first by a market being opened for the sale of grain, and secondly, by the facili- ties afforded to the revenue officers in their search after pri- vate stills : the consequent benefit in a moral point of view is immense. "The soil of the moimtain districts having been hitherto unworked, has been found, by burning and liming, to produce potatoes in such abundance, and of such excellent quality, that very large quantities have been taken from the neighbourhood of Lough Grana (the parts most known to the writer) to the county Limerick, the excellence of the roads making the trans- port easy; thus the deficiency of food in some parts of the 348 INDUSTRIAL RESOURCES country has been made good by the superabundant crops in these mountains. " Gentlemen who before could never reach their properties in these districts, are now led to visit and reside on them, and form plans for their improvement. " In the execution of these roads the resources of the coun- try have been developed ; quarries of stone fit for building, of slate, and of limestone, have been discovered, which will be of incalculable advantage in the imiJrovement of the country, and in thus stimulating the industry of the inhabitants. " In a few years the lands will contribute to the county rates, and thus repay fully the sums assessed for their formation, while the Government will be amply indemnified by the im- proved habits of the people, and the growing consumption of exciseable articles." Such being the results of the opening out of communications through the country, it may well be supposed that it shoxild form one of the dearest objects of a Government anxious for the improvement of the people, and that the sums necessary for such purposes should be most heartily afforded. It is to be regretted that such is not found always to be the case. The benefits derivable are often so remote, and are spread over so great a space of country and of time, that they do not present, to ordinary statesmen, a sufficiently definite aspect to justify the actual advance of sterling money; it may, therefore, be not without interest to point out that such advance is really an investment of capital on the part of the Government, and one generally yielding profits of a high, even usiu-ious return. The town of Clifden in Connamara, and the surrounding country, were, in 1815, in such a state of seclusion that it con^ tributed no revenue whatsoever to the State, and up to 1822, its agriculture was so imperfect that scarcely a stone of oats could be got. In 1836, Clifden had become an export town, having sent out 800 tons of oats, and it produced to the re- venue annually £7,000. From the expenditure in Connaught in eleven years of £160,000 in public works, the increase of / / OF IRELAND. 349 annual revenue derivable from the province has become equal to the entire amount. In Cork, where Mr. Griffith expended £60,000 in seven years, there has been stated to be an annual increase of cus- toms and excise of £50,000 immediately derivable from the territories benefited by those works. Those should not be called grants of money, but investments of capital, with realization of enormous profit. An individual would most happily advance the money if he were allowed to appropriate a fourth of the returns. Such sums, therefore, when advanced by the State, should not be looked upon as boons or favours, as they too frequently are, but as a part of the ordinary duties of a Government. Three quarters of a century ago, when Scotland, poor, bar- barous, and ignorant, lay at the feet of England, withering under the results of two unsuccessful rebellions, the central Government saw the necessity of creating at once such a sys- tem of internal communications, as whilst it enabled the in- struments of Government to penetrate to every portion of the country, should also place at the disposition of the inhabitants the means of pacific intercourse and trade. Hence between canals and roads a million and a half of money was given to Scotland. Of this there was to be no repayment. Other large sums, as a quarter of a million to Leith Harbour, were lent at very moderate interest, and an arrangement was made, that for all roads required in Scotland, the State pays one-half of the expense, and the locality is burthened only with the other moiety. It is not with any idea of objecting to those grants that I here mention them. On the contrary, they were per- fectly proper, and the Government did its duty to Scotland nobly, although some of the plans, such as the Caledonian canal, were failures as to the particular result : but what has been the consequence to Scotland ? How much of the intelli- gence and business habits, the general morality, and amena- bility to law, by which the people of that country are distin- guished, is due to the abundant means of intercourse with each other, and with their richer and more cultivated neighbours ? 350 INDUSTRIAL RESOURCES Certainly a great deal, Scotland furnishes to the State moi*e revenue, in proportion to her population, than Ireland does, but she certainly does not return a larger proportion of profit on the sums which the State has expended in the sound improve- ment of her people. A great deal has been latterly done towards improving the roads of the more remote districts, as also in erecting fishery piers and forming harbours, as shall be hereafter noticed, by the Board of Works, who were enabled to grant loans of small sums of money, for such objects, on other sums being contributed by individuals. Although the restrictions placed upon the Board by its constitution limited its powers very much, forcing it to require a high rate of interest and an un- usual amount of security, yet these loans were in many cases of exceeding use. The grant from the Board of Works formed a nucleus, round which the subscriptions of the local gentry generally accumulated, so that objects for which otherwise no means could be obtained, were thus carried rapidly into effect. Such local works were also of the peculiar use that they could be carried on in general at times when other employment was slack, and they required principally the rough labour furnished by the inhabitants of the district. Thus, not long ago, a part of Kerry, near Kenmare river, was suffering under the mise- ries of almost famine. By the aid of the Board of Woi-ks the construction of some roads was started, and the population was set to work. Being paid their weekly wages, they were enabled to purchase abundant food. Their cottages have ceased to be the abode of disease and misery. A way being opened for the produce of their fields, their agriculture has become more active. A school has been erected on thej-oad side, and industry and education having been now introduced among that so lately wretched people, there is every hope of a steady progress in social comfort. The total sum granted by the Board of Works since its es- tablishment, about twelve years, appears to have been about £104,000. The fund so productive of good consequences was, therefore, about £9,000 per annnm. This grant either has been or is immediately to be abolished. OP IRELAND. 351 The expense of lund carriage is so considerable, even on the best roads, as to present material obstacles to the exten- sion of commercial intercourse. It may be estimated for general goods throughout the country at Gd. per ton per mile, and even under the conditions of steady traffic with returns, as in the case of the carriage of coals from the colliery dis- tricts, I have been obliged to estimate its minimum amount at 3d. per ton per mile. The cost of manufactured goods as well as of produce is thus heightened considerably by the cost of carriage ; their use is limited to a smaller circle of the people, and, therefore, every means that can be devised for lowering the cost of transport should be energetically made available. The most important reduction in the cost of transport is made by the Substitution of water for land carriage. For this Ireland is peculiarly fitted, the extent of her principal rivers, and the number and magnitude of her lakes presenting natural means of communication, such as are seldom equalled, and the structure of the central country affording facilities for the construction of canals not easily surpassed. In fact Ireland is a country peculiarly fitted for inland navigation and for traffic, there being no point on the surface of the island more than twenty-five miles distant from the sea, or from a naviga- ble lake or river. Without entering into lengthened detail I shall proceed to notice each of the principal lines of navi- gation. In every point of view, the Shannon, which has already' ob- tained so much of our notice in relation to the coal fields and iron mines, the agricultural districts, the slate quarries and sulphur ores upon its banks, deserves to rank as the main channel of water communication throughout Ireland. Its na- vigable length is divided into several portions, on which the vessels differ in build and magnitude according to the cu-cum- stances of the river. Below Limerick the estuary is navigated by steamers of considerable size, which ply daily to Kilrush and Tarbert. From Limerick to Killaloe the navigation, partly canal and partly in the narrow portion of the river, is effected by passage boats drawn by horses. The expanse of 352 INDUSTRIAL RESOURCES Lough Derg and the river to Athlone admits again of steamers ; some of considerable size, which ply upon the lake, others smaller for the river channel. Beyond Athlone regular steam traffic has not yet penetrated, but Lough Ree, Loughs Boda- rig and Boffin, and Lough Allen, will admit of being navigated by vessels of the first class, and after a little time the river channel will be throughout so much improved as to allow of the large steamers passing from Killaloe to its most northern termination, and thus dispense altogether with the use of smaller vessels in the narrow waters, and the cost and trouble of trans-shipment. It is singularly illustrative of how little reflection was de- voted to Irish subjects — of how slightly the true and only means of consolidating a people by giving them common habits of industry, of sociality, and of traffic, was thought aboutin rela- tion to this country, that the Shannon was for so many genera- tions looked upon as an useful barrier and defence against the uncivilized tribes, who dwelt beyond its boundary. The cost of maintaining in good I'epair, the various fortifications at what were called the passes of the Shannon, was defrayed with plea- sure, but the ijdea^ of rendering fortifications useless, of erect- ing the bulwarks of the State in the hearts of the inhabitants by fostering their industry, by encouraging their oommerce and agriculture, and promoting their odupatioii, did not occur to the statesmen of that epoch. Lot us hope that a Inttor era has arrived. It is not within my object to enter into any account of the successive steps taken towards the improvement of the Shan- non. Large sums have been expended on it, and these form very frequently a subject of public complaint, from those who either do not or will not understand the vast results to Ire- land, which must flow from the completion of the navigation. A few miles of a canal in Canada, has cost more than treble the entire money laid out upon the Shannon, with this differ- ence, that every improvement of the latter river leads to an increase of revenue which repays the money expended, whilst in the case of the Canadian canal, the money was an absolute and final grant. The alterations now being carried on under OF IRELAND. 353 the care of the Board of Commissioners, are defrayed partly by public funds and partly by a rate levied on the counties along the river. This principle is very equitable, and there is no doubt but that the final result ■will be so advantageous to those districts as fully to atone for the necessity of advancing monej', which certainly is inconsistent with the usual financial habits of the western province. Works such as those in process of execution on .that river, are, in fact, lessons in industry to the population of the neigh- bourhood. The people are not only employed so as to earn a subsistence, but being brought into contact with workmen of a higher class, and of steadier habits, they become themselves gradually improved in character. " Such public works," in the words of Mr. Spring Rice (Lord Monteagle), "produce, as their ordinary effect, extended cultivation, improved habits of industry, a better administration of justice, the re establish- ment of peace and tranquillity in the disturbed districts, a do- mestic colonization of a population in excess in certain dis- tricts, a diminution of illicit distillation, and a very considera- ble increase of revenue." The total sum expended by the Commissioners for the im- provement of the Shannon, up to the 4th March, 1844, is £316,346 lis. Sd. The amoimt of employment given in the construction of locks, &c., along its course, may be judged from the following return of the average number of persons employed daily: 1B4L 1842. 1843.

They are in 1841. 1842. 1843. 727 men. . . . 1884 men. . . . 2064 men. It is now time to close this notice by recording the actual amount of traffic, according to the latest returns that have been published. The actual length of navigation on the lower Shannon, from Limerick to Kilrush, is forty-four miles. The number of pas- sengers by steamers in 1836 was 23,851. The quantity of goods carried at the same time is not given in the returns to the Railway Commissioners. The navigation by track-boat between Limerick and Kiila- loe, which is partly river and partly canal, extends for four- teen miles, in a circuitous course. In 1836 there were taken by packet boats 14,600 passengers, and the trathc was : In 1831, 28,212 tons, paying £1092 14s. Od. tolls. In 1836, 36,018 „ „ £1514 2s. Od. ,, On the Middle Shannon the navigation is lake, river, and partly canal. There are on it five steamers of a total tomiage of 710 tons. One of 100 horse power ; the others of from 20 to 30. In 1836 the number of passengers was 4083. The quantity of traffic at two distant periods is shewn by the fol- lowing numbers. The smallness of the tolls is owing to the relations of the Companies of Inland Navigation, and of the Grand Canal. YEARS. NO. OF BOATS. TONNAGE.

Of the other rivers which penetrate to such considerable dis- tances into the interior of the country, there are few available for navigation beyond the points where the estuaries terminate. The Blackwater, which, at least to Fermoy, a distance of thirty-five miles, might be so easily adapted to navigation, is as yet available only to Cappoquin. On the Suir, the trade boats ascend to Clonmel ; on the Nore to Innistiogue. The Bar- row, however, affords an example of our river navigation fully developed, as by means of it, and of a branch of the Grand Canal, a water communication is established between Dublin and New Ross. The total length of the navigation opened out from Dublin to the sea below Waterford, is upwards of 120 miles. The boats are from 30 to 50 tons. The traffic was in 1800, 19,828 tons, producing £1,405 tolls. 1820, 41,262 ,, ,, £3,827 „ 1835, 66,084 ,, ,, £4,966 „ Some other rivers, as the Foyle, the Slaney, are navigated 2a 2 356 INDUSTRIAL RESOURCES to a certain distance with the assistance of the tide, but they are not at all navigable in the proper sense, as applied to their ordinary river channels. The natural difficulties which rivers often present to navi- gation, as well as their not being found in the precise localities where other conditions render moans of communication impor- tant, render it often more economical to create a perfectly new route by a canal, than to alter or improve the circumstances of a river. The canals of Ireland are referrible to two systems ; one destined to connect the Shannon with the Irish Sea at Dublin, the other to connect the great inland sea, Lough Neagh, -ndth the British Channel at Newry and Belfast. The Royal Canal from Dublin to the River Camlin, by which it enters the Shannon, at Tarmonbarry, has a total length of ninety-two miles. Its summit level is at Mullingar, where, at fifty-three miles from Dublin, it is 322 feet above the level of the sea. Its supply of water is derived from Lough Owel.

The total number of passengers who travelled by this canal, in the year 1837, was 46,430. The Grand Canal, leaving Dublin by the southern extremity, passes nearly parallel, and at a very few miles distance, from the Royal Canal, for a certain portion of its length. It joins the Shannon at Shannon Harbour, and, on the other side of the river, is continued to Ballinasloe. Its total direct length is ninety-nine miles. Its branches are numerous ; to Kilbeggan, and to Edenderry ; to Athy, where it communicates with the OF IRELAND. 357 River Barrow, to Portarlington, to Mountmellick, and to Naas. In addition, there are two branches into the great boggy dis- trict of the central countries, the drainage of which partly supplies the canal with water. These branches serve also as reservoirs, there not being any natural lakes along this line. The total length of these extensions of this navigation, is sixty- five miles, making, in all, 164 miles of canal. The stmimit level is about Robertstown, at a distance of twenty-six miles from Dublin, and 279 feet above the level of the sea. The number of passengers travelling by the packet boats on the Grand Canal, was, in 1833, 54,812; in 1835, it rose to 72,748, and, in 1837, was 100,695.

It commences at Belfast, its entire length from which is twenty-eight and a-half miles. Its course is partly tidal, partly river, and partly canal. The usual tonnage of the boats is fifty tons. In 1836, there passed 894 boats, carrying 44,700 tons of goods, and paying £2,060 10s. 8rf. tolls. The toll is 9^d. per ton for the entire length, and the freight, from 5s. to 6s. The Newry Canal, communicating with the sea, about two miles below the town, passes northwards, for sixteen and a-half miles (Irish), to Whitecoat, where it joins the Bann, and by it passes into Lough Neagh. There are no passenger boats on this canal. In 1837, the trafiic was, 102,332 tons, producing, in tolls, the sum of £3,505 lis. 5rf. 358 INDCSTRIAt RESOURCES The coal field of Tyrone, so fully described in the first chap- ter, had been originally supposed to be of much greater extent than subsequent examination has proved, and a canal was con- structed, at the public expense, for conveying its produce to a distance. This canal, of about eleven miles, extends from Coal Island to the River Blackwater, a short distance from its confluence with Lough Neagh. The mining operations of that district being now so limited, the trade on this canal Is pro- portionally small. In 1836, its total traffic was 7,291 tons of coals. Within the last few years, an important line of canal com- munication has been opened, the Ulster Canal, which, com- mencing from the River Blackwater at Charlcmont, near its junction with Lough Neagb, passes to the south-west, by Mo- naghan and Clones, and joins, after a course of forty-eight miles, the Upper Lough Erne. The eastern and western seas are thus nearly connected, by a line of water communication, which only requires some improvements at Enniskillen, and in the lower lake, to be perfectly continuous from Ballyshannon to Belfast, a distance of about 130 miles. This lino has been in operation too short a time, to test its efficiency by the amount of traffic hitherto called into play, yet it is gratifying to observe, that, aXveSiAy, the facilities of transport \\3.\g pro- duced a considerable increase of industrial activity along its course. Thus, in the years ending April 1st, the traffic was 1843, tons, 13,371, producing £1,261 toll, 1844, „ 17,583, „ £1,976 „ The increase being, one-third of tonnage, and one-half of tolls, shewing the increase of traffic in the more valuable com- modities. Through the valley of the Boyne from Drogheda, by Slane, to Navan, a distance of nineteen miles, and below Drogheda for two and a-half miles to the sea, a navigation is carried on, partly by the livor channel and partly by canal. There are no passage boats. lu IS^IG. the total tralfic was 10,194 tons, producing about £G40 in tolls. Sucii being the circumstances of the canal and river naviga- OF IRELAND. 359 tions, it remains to notice the mimerous lakes available for the purposes of communication. Some of these have been already mentioned, as, in fact, expansions of the Shannon, and need no further reference. In many places, lines of canals have been proposed, and some surveys executed, which, however, have not led to fur- ther results. A very useful project of this kind, was the im- provement of the navigation of the Nore, above Innistiogue. Pei'haps, however, the most important line of inland naviga- tion proposed, in addition to those already existing in Ireland, is that for which surveys were executed by Mr. Mulvany, and which would connect the Ulster Canal and Lough Erne with the Shannon, at Leitrim. The length of canal on this line would be twenty-eight and a-half miles, and twenty-one miles of steam navigation on Lough Oughter, to K'lleshandra. The estimated total cost was £170,000. The importance of this connexion may be estimated by a glance at the map, when it will be seen, that the network of inland navigation of the north- east of Ireland, is separated from the water communications of the south and centre, by the tract which this canal would in- tersect, and that, consequently, the two systems of traffic, now isolated, would by it be placed in connexion. Limerick would thus come into direct communication with Enniskillcn and Ballyshannon, on the western, and with Belfast on the eastei-n, coast of Ulster, and a total line of 716 miles of inland naviga- tion be opened out. The want of water carriage, in that part of the country, is shewn by the fact, that the heaviest articles of traffic, even timber, are brought from Newry, to Ballina, within a few miles of the Shannon, more by land, at an ex- pense of 6f/. per ton per mile, whilst water carriage, including all expenses of freight, tolls, &c., never exceeds 2^d. Inquiries lately made with reference to the drainage of the districts along this proposed canal, have shewn the feasibility of an important modification of it, in which the line passing from Leitrim by a series of small lakes and river courses, at present navigable but not connected, should reach Lough Erne direct, and the artificial water cuts, in place of being twenty- eight and a-half miles, should be but eight. The cost of com- 360 INDUSTRFAL RESOURCES pletiiig this important navigation in this form shonUI be but £80,000 beyond the expenses of drainage tor agricultural p\ir- poses. Ireland possesses not only the largest river in the British Islands, but also the largest inland sea, Lough Neagh, the coasts of which are formed by the Counties of Derry, Antrim, Tyrone, Armagh, and Down. Its area is estimated at about 100,000 acres. Its height above the sea is forty-six feet. It drains a considerable extent of the east of ITlstei-, the rivers Blackwater, Upper Bann, and Ballinderry flowing into it, and its superfluous water being removed by the Lower Bann. The shores possessing but little elevation, it is destitute of the pic- turesque character which heightens the interest of so many of our lakes, but as it presents above 100 miles of coast in a country swarming with an intelligent and industrious popula- tion, and by the Coal Island, Nowry, Ulster, and Lagan Ca- nals it is placed in communication with a large extent of the north of Ireland, it promises to be the future centre of exten- sive internal traffic. Already a commencement has been made. Steam vessels have been placed upon the lake, which collecting at various ports on the northern and western shores, the goods and jjassengers, convey them to the south and east. Porta- down, which unites the advantages of being placed on the Bann, pear the junction of the Newry Canal, and of being the pre- sent terminus of the Ulster Railway, is the principal emporium of the traffic on Lough Neagh. This precise amount of the steam traffic, I am not able to state in exact numbers, though it is certainly considerable. The upper and lower Lough Erne, extending altogether a distance of about thirty miles, have been rendered in great part available for internal comnmnieation to Enniskillen, by the completion of the Ulster Canal. In fact, the multiplicity of islands in the upper lake renders its navigation similar to that of a canal. The lower lake, however, presents an important field for tlie introduction of steam traffic upon its ample sur- face. Its area is 27,045 aci'cs. It is situated in average 150 feet above the level of the sea, and the channel contracting OP IRELAND. 361 above Belleek to the river form, its waters are precipitated over a ledge of rocks, forming a magnificent cascade. Again at Ballyshannon a similar cataract occurs, by which the waters of this great basin are finally passed into the sea. The power of these falls of water has not been accurately calculated. It is certainly equivalent to many thousand horse in constant operation, and, if utilized with the facilities which those lakes and the canal would give for distribution of produce, the result should be most beneficial to the population of the surrounding districts. After the Shannon at Killaloe and Doonas, there is nothing in Ireland comparable as a source of mechanical power to the Erne at Belleek and Ballyshannon. The picturesque solitudes of Lough Gill have been invaded by the power of steam for communicating between Sligo and Dromohaire. When the Shannon improvements are completed, the steamers on Lough Allen will be separated from those of Sligo by only a few miles of hilly country, presenting no insu- perable obstacle to intercourse. The province of Connaught is, however, that which deserves most attentive notice in relation to its navigable lakes. Its soil is not inferior to that of the rest of Ireland ; some of the sweetest pastures, and most productive lands, are found with- in its limits. Its coasts abound with fish ; its mountains are rich in ores ; its people are willing to work, and travel hun- dreds of miles seeking for work, even at a rate which only allows them to sustain existence. Yet that province is the reproach of Ireland and the bye-word of Great Britain. Its population is relieved by charitable subscription from recurrent famines. Little more than one-half of its area has been made available for cultivation, and it is but a few years since its in- terior was first rendered accessible to industry by the forma- tion of proper roads. There exist in Connaught, independent of the Shannon Loughs which form its boundary, two groups of lakes, pecu- liarly fitted for navigation. The most important of these, con- sisting of Loughs Mask and Corrib, communicate with the sea at Gal way by a river about three miles long, with a fall of four- teen feet, of which the water-power is described in page 86. 362 INDUSTRIAL RESOURCES The area of Lough Corrib is 50,700 statute aci-es. Its length from Galway to Maam by Cong is about twenty-live miles, its breadth very variable, at greatest about fourteen miles. Its depth of water is fully sufficient for navigation. Its islands contain more than 1000 acres of fertile land. The waters of Lough Mask are poured into Corrib, but by subteraneous channels, the lakes being separated by a ridge of land of three miles broad. The area of Lough Mask and of Carra, which is an offset from it, is 26,265 acres. Its height eighty feet above the sea level. To bring these three lakes into navigable communication with each other and with the sea, there would only be required about three miles of canal. The direct length of navigation opened would be about forty miles, and a coast of nearly 200 miles would have a cheap and ready outlet for its agricultural produce. The second group of lakes in Connaught stands in connexion with that fine river, the Moy, which draining 1033 square miles of country, falls into the sea at Ballina. These are Loughs Conn and CuUin. Their area is about 14,000 acres. They present a direct navigation of eleven miles and fifty- three miles of coast. The height and power of the fall from these lakes is given in page 86. Surveys of this district, with a view of opening this exten- sive lake navigation to the coast, and thus enabling the inhabi- tants to send out for export the produce of their fields at a low cost, were made by Mr. Bald. He shewed that the carriage by water would be in those localities not more than one-sixth that by land. That by an arrangement of canals, including but seventeen locks, a navigation of fifty-three miles direct could be secured, available to a district containing 800,000 inhabitants, who now possess none but the rudest and most expensive means of intercourse. It is to be hoped that such criminal neglect as has hitherto impeded the progress of all such plans for ameliorating the condition of the people, may not continue. When a famine occurs in Connaught, money is raised in London to buy them bread as charity. It is much fitter that suitable means should OF IRELAND, 363 be adopted for enabling the people to earn it by honest la- bour. When the navigation of the Connanght lakes is proceeded with, it will become an important problem to determine on the mode of communication with the Shannon. For this, various plans have been proposed, but it would be premature for me to enter upon the discussion of any of them. A mode of transport which at the present day occupies public attention much more than the common roads, or water-ways which I have so far noticed, is the railway. Though totally modern, not yet a generation old, this new agent in inter- course has assumed an importance, which entitles it to be con- sidered as a power in promoting the development, not merely of industry, but of civilization. I shall of com-se not enter into any general description of the theoretical circxunstances of railways, or of steam power as used upon them, but having first noticed the condition of the existing and proposed rail- roads in Ireland, I shall apply myself to the brief discussion of two questions which I consider important to this country, that is, in whose hands the general control of railways should be placed, and by what kind of power motion shovdd be pro- duced upon them. We possess in actual operation but four railways in Ire- land. The Kingstown Railway, extending from Dublin to the pier at Kingstown Harbour, six miles, lies along the southern shore of the bay, and may be considered as altogether a pas- senger line for that extensive suburban villa district.

None of the lines here mentioned, require any special notice OF IRELAND. 365 as to the nature of the ground passed over, and details as to their cost and financial condition would be out of place. The importance of railways as a means of developing the industrial resources of a country, especially in the absence of those other aids, by which, in many countries, their ne- cessity is rendered less urgent, had long been felt by all seriously interested in the prosperity of Ireland, and led to the formation of the Railway Commission in 1838, which, under the principal guidance of the late Mr. Drummond and Sir J. Bur- goyne, published a Report, which, although some details of its propositions may be combated or deviated from, remains a mas- terpiece of physical and statistical investigation, and \\'ill connect the names of its eminent authors permanently with the records of Irish progress. The strictness of official caution led to an es- timate of the final return of profit, probably less than the cir- cumstances justified, certainly much less than projectors were disposed to promise in the share market, and hence the effect of the Report was to damp the enthusiasm of railway specula- tions. The principal of governmental control which was strongly advocated in the Report, and to which I shall by-and-by re- turn, was also adverse to the feelings of those disposed to invest money in such undertakings, and was opposed to the existing English practice. Owing to these and other still more unreasonable influences, the provisions of the Report have not been in any one instance carried into effect, and the im- provement of the condition of the people, which its authors had so fondly anticipated, remains as distant as six years ago, when the Report was written. The Commissioners proposed the formation of two great lines of railway, one to the south-west, and the other to the north-west, from Dublin, starting from Bai-rackbridge : the south-western line was to have passed by Palmerstowoi and Lucan to Sallins, Rathangan, Monasterevau, Portarlington, and Maryborough. Near the latter, at the summit of the limestone country, between the valleys of the Nore and Barrow, it was proposed to form a branch to Kilkenny by Abheyleix and Ballyragget. 3G6 INDUSTRIAL RESOURCES " The distance between DuMin and the commencement of this branch is 52^ miles, and thence to Kilkenny is 2C>^ miles, making a total length, from Dublin to Kilkenny, of 79 miles. "From the Maryborough summit, the line has been con- tinued though the limestone country to the road from Borris- in-Ossory to Rathdowney, which it crosses at the distance of 66 miles from Dublin, and three miles from Borris-in Ossory, on the Limerick road ; and this point, which will serve as a station for passengers and merchandize from the towns of Roscrea, Borris-in-Ossory, Castletown, Mountrath, and the districts surrounding them, must eventually become a point of very general resort. "From the road to Borris-in-Ossory, the line pursues its south-western direction, passing near to the towns of Rath- downey, Templemore, and Thurles, to Holycross, in the county of Tipperary, where it is proposed that the line to Limerick should diverge. " This line has been laid out with great care, skirting as close as levels would permit to the south-eastern base of the range of the Keeper Mountains, and thence, without encount- ering any difficulty, proceeding in a direct line to the city of Limerick. " The distance by the proposed line of railway between Dublin and Holycross is 89| miles, and between Holycross and Limerick 35 J miles, making a total distance between Dublin and Limerick of 125^ miles. This distance is only six miles longer than the direct post-road between those points, a cir- cumstance we deem very satisfactory, when it is considered that the proposed railway communication between Limerick and Dublin will be effected by a divergence from the Cork line of only 35 J miles in length. " From Holycross the main Coi*k line proceeds in a southern direction to Cashel, and thence to Marhill, near New Inn, in the county of Tipperary, at which point it is intended that the line to Clonmel and Waterford should commence; but, to complete a direct railway communication between Limerick and Waterford, it is also proposed that this branch-line should be continued in a western direction, from Marhill towards OF IRELAND. 367 Limerick, and, crossing the River Suir at Golden, join the line from Holycross to Limerick at Donaghill. " The distance from Marhill, by Golden, to Donaghill, is 13 miles; and by adopting this arrangement there will be a saving of distance between Limerick and Waterford of 14^ miles ; without it, all the traffic from Limerick to Waterford must necessarily pass from Donaghill, round by Holycross to Marhill, in order to reach the commencement of the Waterford line. " Continuing in a southern direction from Marhill, the Cork line follows the valley of the River Suir to Cahir, situated at the eastern extremity of the Galtees Mountains, at which point, owing to the physical structure of the country, it has been ne- cessary to adopt a south-western course, passing through the narrow valley interposed between the Galtees and Kilworth Mountains, whence it continues by Michelstown to Kildorrery, and thence to the town of Mallow, situated on the River Blackwater. "From Mallow the main line takes a direct southern course to Cork, and necessarily crosses a ridge of slate country, which intervenes between the limestone valleys of the River Blackwater, at Mallow, and the River Lee, on which Cork is situated. " Here experience fully confirms the remarkable circum- stance to which allusion has been made, in treating of the geology of the country, that throughout the whole of the linos which have been described, no engineering difficulties worthy of notice occur, as long as we continued in the limestone country ; but the moment we attempt to cross the slate dis- trict, situated between Cork and Mallow, we encounter an elevation of 222 feet in 7 miles 3 furlongs, which must be over- come by adopting steeper gradients than those required for any other part of the lines we have described, and which never leave the great limestone district of the interior of the country. Owing to this favourable nature of the ground, we have not found it necessary to cross any of those high table lands, which can only be traversed by tunnelling ; but by allowing the lines to undulate to a certain degree with the surface of 368 INDUSTKIAL. RESOUHCES the country, according to the revised system of gradients, all deep cuttings have been avoided. Hence the several rail- ways which we recommend for the south of Ireland can be formed at the comparatively moderate expense stated in the estimate contained in Mr, Vignoles' Report." For the northern line it was proposed to form a trunk to Navan, and from thence two main branches, one west to Enniskillen, and one north to Armagh, which, communicat- ing with the Ulster Railway, would thus reach Belfast. The surveys for this line were executed by Mr. Macneill. The Report proceeds : " By reference to the map it will be seen that the first 28 miles, namely, from Dublin to Navan, are common to both the Armagh and Enniskillen lines ; at Navan they diverge, that to Belfast taking a north course, passing near to Carrickma- cross, and through Castleblaney to Armagh ; the distance between Navan and Armagh being 37^ miles, and the total distance from Dublin to Armagh 85^ miles. " Between Dublin and Navan, where the line crosses the limestone country, the gradients are better, and the average cost per mile will be £4,200 less than where it passes through the slate country already described, which extends nearly for the whole distance from Navan to Armagh. " The north-west or Enniskillen line, on diverging from the Armagh line at Navan, has been laid out in the valley of the River Blackwater, passing through Kells and Virginia. As far as Kells the country is unusually favourable, but between that point and Cavan, and from thence to Newtown-Butler, in the County of Fermanagh, the cost of forming will be consider- able, owing to the hilly character of the slate district. Beyond Newtown-Butler the line passes through the flat country skirting the north-eastern margin of ITpper Lough Erne. In such a locality the gradients, as might be expected, are ex- cellent, and the cost is proportionally reduced. " The town of Enniskillen, situated between Upper and Lower Lough Erne, may be considered as a central station, towards which both passengers and commercial traffic may be expected to converge for a considerable circuit, including the OF IRELAND. 3G9 important towns of Londonderry, Letterkenny, Strabane, Omagh, Donegal, Ballyshannon, and Sligo, and hence, for the present, it is considered to be the most suitable for the termi- nation of the north-western railway. " In forming a comparison of the advantage which the lines to the north and north-west of Ireland, recommended by us, possess over the others to which we have alluded, there is only one which traverses the interior of the country, to which we think it necessary to refer, namely, that from Dublin to Armagh, passing through Ardee and Castleblaney, already mentioned. " For general purposes this line would not be favourable to the views adopted by us ; it is not sufficiently near the coast to be used for connecting the important commercial towns of Newry and Dundalk with Dublin ; and, on the other hand, it does not strike far enough into the interior to render any por- tion of it suitable for a main lint; to the north-west. " In an engineei-ing point of view it is likewise inferior, in- asmuch as it is proposed to cross the River Boyne, by an em- bankment, about 460 yards in length, the greater portion of which, as shewn by the section, would exceed 100 feet in height ; while the line which we propose crosses the river above Navan, by an embankment of 260 yards in length, and at an average height of but 33 feet ; and likewise between Castleblaney and Armagh the line is not so advantageous, either in length or gradients, as that laid out under our direc- tion. " In respect to the coast line, which has been surveyed from Drogheda by Dundalk to Newry, we have to observe, that it may be considered altogether in the light of a speculation which has no reference to the internal commercial traffic of the country, but as one which will afford a desirable facility for passenger intercourse between the important commercial towns which it is intended to connect." Such were the propositions of the Railway Commissioners in 1838. There were also various lines proposed by private companies, of which the following are the most important. A line to Kilkenny, which leaving Dublin at Kilmainham, passed parallel to the line adopted by the Commissioners, but 2b 370 INDUSTRIAL RESOURCES at a higher level, and crossed the Grand Canal at Sallins : it then passed across the Curragh of Kildare to Athy, and fol- lowed the left bank of the Barrow by Carlow to Leighlin Bridge, from whence, along the foot of the Colliery Hills, it passed to Kilkenny. This line, considered solely as regarding Kilkenny, was perfect, but it was not adapted for such con- tinuations and branches as could render it a part of a general southern system. A railway from Limerick to Waterford was one of the first proposed in Ireland, and surveys were executed by Nimmo, whose favourable opinion of the locality has been confirmed by all succeeding engineers. Regarding it the Report says : " By reference to our passenger and traffic maps it will be seen, that between Limerick and Clonmel the present inter- course is comparatively trifling ; but the known resources of the country are so considerable, that rational expectations might be entertained of a favourable result from a railway which would open a direct communication from the coimties of Clare, Kerry, Limerick, and Tipperary, to the markets of Bristol, the south of England generally, and to London. " Still we cannot admit that, if abandoned to its otvti local resources, this railway would yield profits sufficient to re- munerate a comjjany for its construction. But blended, as we propose that it should be, with the general lines of intercom- munication between Dublin, Cork, Limerick, and Waterford, we conceive that the expense of the connecting branch, thir- teen miles in length, between Donaghill and Marhill, already alluded to, will be considered as a minor consideration when compared with the advantage which the country must derive from the completion of a direct railway communication between Limerick and Waterford." A company is now formed for constructing this line, and there is little doubt but that it will be one eminently useful and remunerative. From the period of the Railway Commissioners' Report imtil some few months back, the establishment of extended railwav intercourse through Ireland had been almost totally lost sight of. The formation of the Dublin and Cashel Rail- OF IRELAND. 37l way Companj' has been, however, the herald to a period of ao- tivity and enterprize which, although possessing many of the characters of a speculative paroxysm, cannot pass over with- out conferring vast benefit upon the country, by creating a network of the most efficient means of communicationj^and leading indirectly to a rapid advance of industrial ideas and operations. The number of railway projects now imder con- sideration is so great, and many of them competing and con- flicting lines, that they cannot be expected or desired all to be carried into effect, and it will, therefore, suffice for the ma- jority to mention, in very few words, their general direction. The Dublin and Cashel Railway, the works for which have been just commenced, and which will probably be the main stem of all the lines branching to the south and west, passes by Sallins and Kildare, to Monasterevan, and thence by Por- tarlington, Maryborough, and Thurles, to Cashel. This route differs but little from that recommended by the Commissioners. The country through which it passes is highly favourable. It is thrown rather more into connexion with the intervening tovras, and thereby, probably, the facilities for traffic aug- mented. Cashel is but a small change of terminus from Holy- cross, which the Commissioners recommended, and which will be in practice, most probably, the point of derivation of the secondary lines. There are proposed, in connexion with the main Cashel stem, an extension to Cork, which, passing from Holycross by Tipperary to the north of the Galtee mountains, should pro- ceed by Kilmallock, Buttevant, and Mallow, into Cork. In competition with this, other parties propose to carry out the Commissioners' line, which, proceeding south of the Galtees, passes by Mitchelstown to Mallow, from whence the course of both lines nearly coincide to Cork. Beyond Cork a line will probably be extended to Bandon. From Tipperary a branch is proposed to proceed westward to Limerick, and to be continued on the north bank of the Shannon and Fergus to Ennis. Very important branches of the Cashel line, are those pro- posed to Wexford and Kilkenny, the former starting from the •2 b 2 372 INDUSTRIAL HESOURCES trunk at Kildai'e, enters the valley of the Barrow, and passes by Athy to Cai'low. From thence it crosses through the goi'ge in the granite ridge, and entering the valley of the Slaney, descends by Ne\vtownbai*ry and Enniscorthy, to "Wexford. The Kilkenny branch is proposed to skirt the western edge of the Leinster coal field, passing by Ballyragget and Abbeyleix, and joining the main stem at Maryborough. Short lines connecting Kilkenny and Wexford with Water- ford are proposed. The Kilkenny connexion is proposed to be laid down, as an experiment, with wood, impregnated with plaster of Paris, after trying which the company \\ ill probably adopt some more rational method of proceeding. To bring the western coast at Galway into direct communi- cation, by railway, with the metropolis, is the object of several plans, one of which is to form a branch of the southern line at Portarlington, which, proceeding by Tullamore to Athlone, should then pass by Ballinasloe to Galway. A very simple and economical line might be formed on the bank of the Grand Canal, joining the Cashel trunk at Sallins, and extending to Ballinasloe. Another proposal is to foi-m a line on the banks of the Royal Canal to Mullingar, from whence branches should extend to Longford and Athlone, but it is said that this Com- pany objects to going beyond the Shannon. This is quite fair, as regards the speculators, who naturally wish to have to do only with the most profitable portion, but the Government should look to the benefit of the country at large. The line to the Shannon should not be granted to any company which would not go beyond the Shannon to the western coast. To connect Dublin with Belfast, a line is now proposed, in continuation of the Drogheda line, to Portadown, where it will communicate with tlie Ulster Railway. The distance of this junction line will be fifty-six miles ; with the exception of the vicinity of Newry the route does not present any important difficulties, and Sir John Macneill's estimate for its construc- tion is £12,000 per mile. The general direction is the same as the coach road. From Drogheda there is also contem- plated a railway to Navan and Kells, a distance of twcnty- tliree miles; tiiis line, being principally in the valley of the OF IRELAND. 373 Boyne, along the junction of the limestone and slate districts, is peculiarly favourable, and is estimated to be completed for £10,000 per mile. By an extension of this branch a commu- nication may be formed with the Shannon by Longford, and thence to Sligo, which would give the north of Connaught a very direct means of access to the eastern coast for the expor- tation of agricultural produce, and also probably bring into more active play, the field for enterpi'ize which the vicinity of Lough Allen presents. The Ulster Railway Company are about extending their line by Armagh to Monaghan, and thus opening out the cen- tral counties to Belfast. The line to be pursued beyond that point is not determined on. The inland line abutting on Enniskellan, proposed by the Commissioners, has been already noticed. This being aban- doned now, it is proposed to connect that important town with the Dublin and Belfast coast line, by a railway which should proceed either by Monaghan and Armagh to Newry, or by Castleblaney to Dundalk. The latter line certainly appears the more favourable in its general character. From Ennis- killen a line is projected by Omagh and Strabane to London- derry, and from Omagh also a line has been proposed by Dun- gannon to Coleraine. From Belfast a line is projected to pass by Carrickfergus to Ballymena. Such are the principal plans now under consideration for form- ing railways in Ireland. It is to be hoped that the decisions of those, to whose lot judgment will ultimately fall, may be guided by an enlightened desire for the sound prosperity of the coun- try. In all of the lines of railway so far noticed, whether in actual work or only proposed, the source of power in use or contem- plated is the ordinary locomotive engine. There has, however, been recently brought into play a means of locomotion on rail- ways which bids fair to replace, at least in many localities, that hitherto in use ; it is by atmospheric propulsion, of which, in fact, this country has become the most remarkable example. 374 INDUSTRIAL RESOUKCES by the specimen of it which is in action for a mile and three- quarters from Kingstown to the village of Dalkey. On an ordinary line of railway, as, for example, the Kings- town line, the weight of the train and engine is usually about forty-five tons, of which the engine weighs fifteen tons, and the carriages and passengers about thirty. It hence follows that of the total power required to move the train, one-third is actually absorbed in the motion of the engine without any return. The cost of fuel necessary to produce steam is thus half as much again as should suffice if there were only the use- ful load to move, and the importance of this difference will be at once felt, on considering that the cost of power is by far the largest item in the expense of working a railway, and in the cost of power the fuel is again the predominant item. Thus, in the years ending respectively March 6th and 27th, 1844, the expenses on the existing railways were : ULSTER. KINGSTOWN. Cost of power, .... £3729 12 8 £8128 18 8 Of which the cost of coke was, 1850 9 10 2264 17 H Whilst the cost of main- tenance of way was but 1048 10 7 2253 11 8 And the total gross ex- penditure, .... 14539 20599 12 6 The annual cost of the fuel expended in giving motion to the engines, without reference to the carriages, goods, or passen- gers, and on which no profit accrues, is, consequently, on the Ulster line, about £600, and on the Kingstown line, about £750 per annum, besides a proportion of the general expenses which cannot be well separated. The great massiveness and weight of the locomotive engine render necessary also a degree of strength in the rails, bridges, and embankments of the line, which otherwise might w ell be dispensed with. Thus we may consider a passenger carriage to weigh, as is usual, three tons, and to contain twenty-eight passengers, Avhieh, at fourteen to a ton, gives two tons, making the whole weight five tons, or we may allow it to be even six OF IRELAND. 37-5 tons, which, if the carriage be provided with but four wheels, gives a pressure upon each wheel of a ton and a half. The construction of all the bearing parts of the railway must be in accordance with this amoimt of pressure. If, however, the locomotive engine be taken into account, its weight being con- sidered, as is usual, as fifteen tons, and that it be supported on six wheels, the pressure on each wheel is two tons and a half, and the strength of every portion of the line must be aug- mented beyond what would suffice for the paying part of the train, in the proportion of 5 to 3. Now to make the railway stronger, in the ratio of 5 to 3, involves far more than an in- creased expense in the proportion of 5 to 3, and it may be safely asserted that so far as all the parts which are common to both systems of locomotion on railways are concerned, the existence of the locomotive engine considerable increases the necessary expense of construction. On the principle of atmospheric propulsion, which is now in action upon the short railway from Kingstown to Dalkey, the power is applied at a fixed point to work an air pump, by which the air is continually removed from an iron pipe, which is laid down along the centre of the line. The carriages are con- nected with this pipe by a piston, upon which, when the inter- nal air is exhausted, the external air presses, and as it is found practicable, on the line of a mile and three-quarters, to obtain a vacuum of twenty-four inches in the barometer, there is gene- nated an effective pressure of twelve pounds per square inch of piston area, or for the pipe of fifteen inches diameter, a force of 21291b. The valve mechanism which regulates the passage of the air, and opens and closes the apertures in the tube as the train passes, is found in practice to be so far perfect as to leave, after all leakage, a force equivalent to that of the most powerful locomotive engines, generated in the most economical manner, and possessing in'its application peculiar advantages for railway intercourse. In the cost of power it has been shewn, that one of the larg- est items is the cost of coke. On the Ulster Railway, the coke cost 34s. per ton, mitil they began to manufacture for them- 376 INDUSTRIAL RESOURCES selves, and even then it cost 26s. The Dublin and Kingstown Company pay for coke at the Gas Works 2Ss. 4f/. per ton. Now in the locomotive boiler the coke does not evaporate more than eight times its weight of water : but if the fuel be bm-ned under a fixed engine, and that in place of coke, coal be used, which can be had for 12s. per ton, the ton will evaporate, with Cornish boilers, at least twelve tons of water, and the steam power, to produce which should cost £1000 for coke in a lo- comotive engine, may be generated with the fixed engine for £S'33 worth of coal. Not merely may coke be burned to work the air pump of an atmospheric line, but in localities where coal might be expensive, turf may be used, and thus the system becomes at once applicable to the centre and west of Ireland, where gas coke should be unattainable except at a great expense. The advantages of fixed power do not even stop here. The power need not be that of steam. At every change of level along a line of railway in this country, water power may be made available, and in such case the economy in substituting it for the most expensive form of steam power may be estimated from what has been so fully discussed in the third chapter. A further important economy in the principle of fixed power communicated by the flexible medium of the atmosphere, is that its cftect does not alter with the inclination of the road. On an incline the locomotive engine has to draw up itself as well as the train. Let us suppose an incline where the total drag on the engine is doubled ; now unless the velocity of the transport is sacrificed, or an additional engine employed as help, the size of the train must be reduced, and this reduction must be made altogether at the expense of the paying part of the train, so that finally at certain inclines the engine could only draw itself up, and be incapable of bringing any load. It is this peculiarity of the locomotive engine that has hitherto rendered it the object of engineers to avoid inclines, and to re- tain the lines as nearly horizontal as possible, even at a vast sacrifice of cost in the construction. If, however, the power be fixed at a distance, and be brought into action on the train by the fioxible medium of the atmosphere, the mechanical force OF IRELAND. 377 will always move a proportional amount of carriages or goods, while the heavy locomotive being absent, all tend to remune- rate the line for the loss of transport. Hence, inclines are available on the atmospheric plan, which would be absolutely impracticable on a line worked by locomotives, and by this, as well as the other considerations previously noticed, the gene- ral engineering conditions of the railway become exceedingly simplified. The more intimate connexion with the line by the pipe and piston which gives steadiness to the atmospheric train, and enables it to traverse curves too sharp for the safe passage of an ordinary train, is another advantage : besides that the absence of the locomotive, from which, in most cases of acci- dents, the injury is sustained, presents an additional source of safety. The only source of expenditure on an atmospheric line, which does not exist to as great an extent on the locomotive line, is that of the iron exhaustion pipe. This, however, cannot be equivalent to the sources of economy I have described, and hence I do not hesitate to conclude, that in regard to facility of execution, of economy in working and construction, and in safety and rapidity of transit, the principle of fixed power working by atmospheric pressure deserves the most attentive consideration on the part of those engaged in railway enter- prizes, especially in this country, where the substitution of cheap coal, or turf, or still cheaper water power, for expensive coke, may, in many districts, make the difference between a profitable line, or a losing speculation. Such being the general conditions of the application of at- mospheric power to locomotion, it remains to notice the gene- ral construction of the trial line now in operation between Kingstown and Dalkey. It is erected on a line of tramway formerly used for conveying stone to Kingstown Harbour. The total length is a mile and three-quarters. Its average inclination is 1 in 115, but in some parts it is 1 in 57: a slope on which a locomotive engine could move little besides itself. It presents several curves sharper than any constructed on or- dinary lines of railway, one of less than an eighth of a mile 378 INDUSTRIAL RESOURCES radius, so that on this short lino there are actually so many obstacles, that its success may be considered as decisive, so far as the application of the power is concerned. The engine at Dalkey is of 100 horse power ; this is, for iilterior objects, much greater than that required. The usual average velo- city of the trains ascending the line is thirty miles, but a ve- locity of sixty miles per hour is easily attainable. The trains descend the line from Dalkey by the force of gravity. They occupy usually about three minutes and a half in the ascent, and about foiu* minutes in the descent of the mile and three- quarters. The pipe used on this line is fifteen inches diameter. It is in ten feet lengths, which weigh each twelve cwt. There should be, therefore, per mile 528 lengths, weighing 317 tons, and the iron in the screws and valves might amount to about sixteen tons, making a total of 333 tons of iron per mile of sin- gle way, which is the only point in which this mode is more ex- pensive than the ordinary railway. The Dalkey atmospheric line will probably be extended to Wicklow, or even farther south along the coast, and thereby satisfactoi'ily bring into play the full powers of this remark- able mechanism of locomotion. The influence of the railway system on the industrial and social circimistances of the country, is so great, as to demand, upon the part of the Government, the most careful super- vision. This has not been as yet accorded to it. When rail- ways were first proposed, their results were not foreseen, nor their vast power understood, even by their advocates, still less by the Government, and hence, being looked upon as individual speculations, into which every capitalist should be at liberty to enter, when and where he liked, and to realize as much pro- fit as he could, there was only required a parliamentary pro- cediu"e, similar to that necessary for obtaining permission to open a new line or branch of common road. The railway, when once opened, took possession necessarily of the entire intercourse between its terminations. It instantly abolished the usual and previous modes of travelling, and this once ef- fected, all fear of competition was removed, and the cost of the transport was rendered such as the managers thought would OF IRELAND. 379 be most remunerative. The velocities were also kept far be. low what the system is capable of producing, for the expense increases very rapidly with the velocity, and hence to obtain the greatest amount of profit the speed must be kept low. When a proposition for a new railway is brought before Par- liament it is inevitably o^jposed, either by those who, desirous of forming a line in a different direction, advance their claims to a monopoly of their own ; or by such as, having property along the line, are desirous of obtaining the greatest possible amount of compensation, and seek to enhance their importance by strong representations of the injury they sustain. By such opposition the expense of obtaining the necessary bill is enor- mously increased ; landed proprietors of influence in either house, through whose localities the line may pass, require to be conciliated ; the energies of the law agents and others em- ployed for the adverse parties, are exerted to the uttermost, as, no matter how the railway eventuates, whether the pro- prietors ever realize a fraction on their investment, or the pub- lic derive any increase of means of intercourse, the law and engineering expenses must be paid, no matter how enormous they may have become. Those expenses have actually amounted in many cases to £2000 per mile on the entire line, and in ave- rage are not less than £1000 per mile, wherever there is opposi- tion, no matter whether well founded or not. All this must ultimately be defrayed by the public. The companies regard it of course only as a part of their investment, on which profit is to be made equally with that for the construction of the rail- way, or for the expenses of the power. These preliminary operations fm'nish, however, a rich harvest to solicitors and engineers, and hence have arisen throughout England a vast number of railway enterprizes, which, undertaken without suitable investigation as to their final results, have brought ruin upon those persons who were induced to embark their pro- perty in them. There are altogether in operation in the Bri- tish Islands 1732 miles of railway. Of these 1014 miles pay an interest of £6 6s. 7c?. per £100 on their capital, which amounts to £4 19s. 4rf. per cent, on their market price. There are 571 miles of railway on which the return in no case ex- 380 INDUSTRIAL RESOURCES ceeils £4 per cent, on the paid up capital : in a few it amounts to £2 10s., and in some but to lOs. per £100. The remaining 147 miles consist of branch lines, subordinate to the first class, and producing about from 3^ to 4 per cent. It is thus evident that nearly one-third of the entire extent of railway in England has been an absolutely unfortunate speculation, and yet on these bad lines a total capital of £18,500,000 has been ex- pended, the present value of which is now not more than £13,000,000. On the other hand the companies which are in possession of the great lines of intercourse realize enormous profits. The London and Birmingham having cost £3,923,000, pay £11 2s. per cent. The Liverpool and Manchester, and Grand Jimc- tion, having cost respectively £1,515,000 and £2,319,000, pay each £10 per cent., the maximum allowed by law. The lines of intercourse being thus absolutely private speculation, one set of capitalists are ruined, another set are enriched, but the public, so vitally interested in the main question of facility of intercourse, is left totally out of consideration. With those examples of profit on one side and of loss upon another, it is easily understood that no difficulty would be found in obtaining capitalists ready to construct those leading lines which are certain of being the great means of intercourse with the capital of the country. But capitalists will not be forthcoming to extend those lines into the variety of districts where the means of intercourse are most required ; where the railroad would be a som-ce of social stimulus towards improve- ment, and by connecting together the most remote parts of the island, and the extremes of our civilization, diffuse the activity of industry and good example over all its parts. That would not pay. The great trunks near Dublin will certainly pay ; and hence the capitalists will obligingly take possession of them. And similarly, if all the provisions which come up for the supply of Dublin, were conducted to the same market, and that the power was given to an individual to levy what toll he liked before the inhabitants could get any food, there is no doubt but that we would find capitalists ready to build the OF IRELAND. 381 market. Such a case is just the parallel to the main trunk railways. Let us conceive this country destitute of roads, and that an individual undertook to make a road, on condition that no per- son should be allowed to travel or hold communication with his neighbour except by his road ; that no person should, w-hen on the road, travel at a greater or less speed than the owner of the road approved of ; that no person should travel at any other hours than those which the owner ordered ; and that the owner should have the power of charging any sum he chose for the use of his road ; and finally, that this power should be eternal ; that no matter what advances the district made in industry, intelligence, activity, it should still remain bound to the conditions of this road proprietor. Would not this be an intolerable grievance ? And yet every item in that catalogue is realized in the actual circumstances under which railways are placed. For the idea of competing lines, which shall keep the existing companies on their good behaviom', is perfectly chi- merical ; the practical fact being, that the railway, once formed, is a monopoly of the strictest kind. Similar considerations have presented themselves to almost every person who has had occasion to study the general rela- tions of railways. The following passage from the concluding section of the Irish Commissioners' Report, is illustrative of the general argvunent, and valuable in addition, as shewing the deliberate opinion of some of the most eminent men by whom questions of the kind have been considered. " It is a favourite opinion with many that all undertakings of this description are best left to the free and unfettered ex- ercise of private enterprise, and that the less the State inter- feres, either in prescribing their execution, or controlling their subsequent operation and management, the better. " We are fully sensible of the great advantages to be ob- tained by allowing full scope to the vigour, energy, and intelli- gence of individuals associated for such important purposes ; and that it would be equally inconsistent with the interests and with the rights of society were such exertions crippled or re- strained by unnecessary or impolitic regulations. But we I 382 INDUSTRIAL RESOURCES prehend that the essential diiference between railways and any other description of public works has been overlooked, and that power and privileges have been conceded to private com- panies', which should be exercised only under the direct au- thority of the State, or under regulations enforced by effective superintendence and control. " So great are the powers, so vast the capabilities of a rail- road, that it must, wherever established, at once supersede the common road ; and not only will all the public conveyances now in use disappear, but even the means of posting will, in all pro- bability, rapidly decline, and eventually, perhaps, cease to be found along its line. These effects may be expected as the necessary consequences of opening a railway. Its superiority is too manifest and decided to admit of rivalry -, it possesses almost unlimited means of accommodation ; no amount of traf- fic exists on any road, or is likely to exist, which a single rail- way is not capable of conveying ; no concourse of passengers which it cannot promptly dispose of; the velocity of the loco- motive, when impelled even at a very considerable reduction of its full power, surpasses the greatest speed which the best appointed coach on the best made road can maintain : in short, where the capabilities of the system are brought fully into ope- ration, they present such an accvmiulation of advantages, as to render it an instrument of unequalled power in advancing the prosperity of a country. ' ' It therefore deeply concerns the public, whose welfare is inseparably connected ^vith all that tends to improve the in- ternal resources, or to maintain the commercial and manufac- turing superiority of these counti-ics, that such works should be promoted ; and consequently, every encouragement, consis- tent with the regard due to other interests, should be given to capitalists who may be willing to undertake them. Their pro- positions should be submitted to a competent and duly consti- tuted t)-ibunal ; and if approved, sliould be adopted and stamped as national enterprizes. As such they should be protected from all unnecessary expense — from extravagant demands for com- pensation — from vexatious opposition, and from the ruinous OF IRELAND. 383 competition of other companies. To that extent they have a strong claim on the protection of the State. "But, on the other hand, the public interest would require that they should be bound by such conditions, and held subject to such well-considered regulations and effective control, as shall secure to the country at large the full benefit and accom- modation of this admirable system. " The practice hitherto followed in England has been almost the very reverse of that which we here recommend. No pre- liminary steps are taken on behalf of the public, to ascertain whether the proposed railroad be well adapted to its specific object, or calculated to form a part of a more general system. The best and the worst devised schemes are entertained alike, being equally exposed to ojjposition, and left equally impro- tected against the difficulties which interested parties may raise up against them. Nay, a railway bill may be passed, or it may be rejected ; but the fate of the project merely proves the number and influence of its respective supporters or oppo- nents. Its failure or success is no test whatever of its merits, as a measure of general utility ; for that consideration forms a very small part of the inquiry before Parliament." It appears from all these considerations that the great chan- nels of public intercourse should not be rendered private pro- perty ; that, in the language of an enlightened Belgian minis- ter, to whose reports on other subjects I shall have occasion elsewhere to refer: " the object desired in the construction of a railway should be not the gain of an individual, but the ex- tension of the traffic and communications of the country to the utmost limits of the public capability, at the lowest rate of charge, at which the original outlay can be reimbursed." . . . " The project undertaken by Government is an establishment which should neither be a burthen nor a source of revenue, and requiring merely that it should cover its own expenses, consisting of the charge of maintenance and repairs, with a further sum for the interest and gradual redemption of the in- vested capital." The systems upon which the railways of Eng- land and of Belgium have been constructed are thus completely 384 INDUSTRIAL RESOURCES opposite, and the way in which each worjcs, is such as might have been expected from this opposition of principles. As the able author of the pamphlet entitled Railway Reform says : " The object of the one is to tax the public the maximum of the most profitable rate, that of the other the minimum of the most economical expenditure ; the one to produce the greatest profit to private individuals, and the other to confer the greatest benefit on the whole community. What are the relative charges by each ? On one of our railways, from London to Birming- ham for instance, the distance is 112 miles, and the fare by the mail is £1 12s. 6d. For the same distance in Belgium, in a similar class carriage, the fare would be fourteen francs, or just one-third of what it is in England." I have endeavom'ed thus to explain the reasons which have induced me to conclude, that it is, at the present time, a vital question with this country, on what plan the organization of a network of railways should be constructed. I have left out of question the argument which has often been advanced vidth much force, that private companies proceed to the execution of such works with a carelessness of expenditure which could be avoided if the entire were under strict central superinten- dence. It is true that many lines of railway in England have cost sums so enormous, as to manifest the most wasteful ex- travagance, or the most discreditable carelessness, but I con- sider that a great jDart of this high expenditure arose from the ignorance and timidity of engineers, who, the system being in its infancy, considered themselves limited to a horizontality of line, which enormously increased the outlay. The future lines, whether private or governmental, will be much more economically executed than such undertakings have hitherto been. This, however, does not alter the general conclusion that the great highways of the country should belong to the country, and that the means of intercourse of the population should be under the regulation of the State. It is of course not within my duties nor my powers to propose such measures as would give the public a proper control over the times, charges, and velocities of the means of intercourse. Such plans have been brought forward, and by those whose OF IRELAND. 385 knowledge and position rendered them peculiarly competent to the task. Thus let capitalists make the railway, but let their investment be not a speculation but a stock, on which they should get a secure but limited interest, and at 4^ per cent, abundance of capital could be obtained ; let the districts within a certain distance of the line secure that interest ; if the railway realize a higher interest, let the difference go to alleviate the other burthens on the land of the vicinity. Now it must be recollected that no prudent capitalists will make a railway for themselves, unless with a moral certainty of its pay- ing more than 4|- per cent., so that the diffei'ence of result is, that should the line be made by the capitalists for the country, if it paid 6 per cent, the country would have 1^ profit to apply to other local objects, and could control velocities, arrange hours, and reduce fares as they thought fit, whilst if the capi- talist make the railway on his own account, he pockets the entire 6 per cent, of profit, and the public has no control, but must submit to any regulations he likes to make. The landed proprietors in many of our counties were, how- ever, terribly frightened at the idea of the localities being made liable for the interest, and the most exaggerated state- ments were circulated as to the amount for which the districts would thus be responsible. I believe that if the subject was generally understood, this alarm, which was so fatal to the im- portant principle of keeping in their own hands the control of their own highways, would be dissipated. The probable lia- bilities have been in fact accurately calculated, and are as fol- lows : If we suppose, as was at one time contemplated, three trunk lines issuing from Dublin, and fiassing northwards to Armagh, westwards to Mullingar, and southwards to Cashel, their cost, according to the highest estimate which had been made, should be. To Cashel, 100 miles, £1,300,0(30 To Mullingar, 49 miles, 459,600 To Armagh, 92 miles, 1,185,100 Total, 241 miles, £2,944,700 2 c 386 INDUSTRIAL RESOURCES And to secure the repayment of 4^ per cent, interest, the dis- tricts through whicli^the lines passed should be liable to assess- ment, in proportion to their vicinity to the railway, and the probable benefit derived from it. If the line realized 4^ per cent., of course the districts had nothing to pay. If it realized more than 4^^, of course the districts had the overplus as abso- lute gain. But if there were a deficiency of receipts of 1 per cent., then the localities should be assessed in the amount of from nine-tenths of a penny, to one and two-tenths penny per statute acre of arable land per annum, for the lands judged most benefited, and in from one-sixth to one-tenth of a penny for those least benefited. Supposing no return whatsoever on the railway, and that the entire interest had to be made up, the tax should be per acre of arable land, from4J. to 5jd. for the districts most, and Id. to 1|8. where tiie precise proportions of a factory are given, the total expenses of transport to Ireland arc 1 "4 per cent, of the n suit. Tills is probably not exceeded, if it lie equalled, uj)on OF IRELAND. 393 any other part of the eastern coast. In the case, however, of the development of manufacturing enterprize upon the western coast, and along the Shannon, the cost of transport of cotton from Liverpool would be much heavier. If paid for by ma- nufactured goods, the cotton of the Southern States, or of Surat, would be delivered in Limerick or Gahvay, freed from the delays and danger of a channel voyage. It will be, indeed, an epoch in the history of Ireland, when a bale of cotton direct from New Orleans is spun and woven at Killaloe, and in part returned as printed calicos or muslins from Limerick to the States. The man who first accomplishes that, or any equiva- lent result, will have effected a revolution. The woollen manufacture has been at all periods considered as of high importance in this country, so that at certain times it was deemed necessary to take measures to moderate its prosperity. Where ill-judged efforts for its encouragement alternated with violent attempts at its suppression, the ob- ject of the latter was of course finally accomplishod, and at present the woollen trade does not form an exception to the general stagnation of industry, which is so unfortunately characteristic of this country. In considering how far the natural condition of Ireland leads us to expect the develop- ment of this industry to any important degree, it is ne- cessary to consider the growth of wool which we possess, not merely in relation to its quantity, but also to its quality and structure. A very large quantity of wool is grown in Ireland. The grazing counties of the limestone plain afford an herbage peculiarly agreeable to sheep. The total number of sheep in Ireland is given in page 258, as somewhat above two millions. In Ulster, where industry and agriculture are most advanced, the pastoral habits are weakest. In Connaught the reverse conditions exist. To 100 acres of arable land, there are in Ulster but six sheep, wliilst there are in Connaught twent}'- four. It would be useless to attempt to calculate from this, the quantity of wool, as in iact each fleece yields numerous kinds of wool, which form (juite distinct objects of manufacture. There is no doubt, however, but that were the wool grown 394 INDUSTRIAL RESOURCES in Ireland manufacturtd in it, there shoukl be called into play so great an amount oi' mechanical industry, as would aiford employment to a large portion of the people. At present great tpiantities of wool are exported from this comitry, particularly to France, and several French houses have established agencies in the centre and west of Ireland for the more direct purchase of the wool. This wool is in France manufactured into the mousselines de laine, so deservedly popular amongst our coun- trywomen, by whom, I trust, they would not be less esteemed, had they been spun, and woven, and printed without leaving Ireland, and thus have given comfortable means of living to thousands of our countrymen. There are two kinds of woollen goods, which are formed by different modes of manufacture, and these, again, are founded on essential differences in the structure of the wool. Worsted goods are formed of wool, the fibres of which are long, and have little twist. In such goods the web is formed only as the web of cotton or linen goods, by the opposition of the fibres, alternately crossing and parallel. But, in what are properly woollen goods, as in broad cloths, after the web has been so formed, it is subjected to a violent beating, in the tucking or fulling mill, during which the cloth shrinks very much in length and breadth, but thickens, and the individual threads of the web so mix in with each other that they cannot be distinguished, until it is much worn, and becomes thread-bare. Now, for such goods, a different kind of wool must be taken than for worsted goods. The fibre must be short, and more twisted. These varieties of wool are known as short and long stapled. The cause of this difference is, that each fibre of wool consists of a series of joints, and at each joint there are a set of pro- jections, like the barbs of a fish hook. In long stapled wool these barbs are few, and very weak ; in short stapled wool they arc numerous, and strong. If a handful of the latter be worked in the hands, the fibres will gradually interlace, and, by these barbs catching in each other, will lock into a kind of web, quite independent of spinning and weaving : they will felt. It is in this way that tlio liodies of hats are made, as all furs possess the same property. Hence, the making of cloth requires the OF IRELAND. 395 spinning and weaving of the web, in the first instance, and the subsequent partial felting of the fibres, in the tucking mill. I notice these particulars, as the climate and vegetation of a country exercise remarkable infiuence on the staple and struc- ture of the wool which the sheep produce, and thus, finally, on the description of manufactured goods. In moist cold climates, such as that of the British Islands, the natural wool of the adult sheep is universally long stapled, and unfit for felting: whilst in dry climates, with hot summers, the wool is short stapled, and felts strongly. The wool produced not merely in Ireland, but in England also, is thus exclusively adapted for the worsted trade; and that of Ireland being of an excellent qua- lity of fibre, is much sought after for the finer kinds of worsted, such as those already noticed of French manufacture. For woollen cloths, and similar goods, the wool is imported from the Con- tinent. The great plains of the east of Europe support vast flocks of sheejj, from whence we derive our Silesian and Saxon wool. The dry plains of South Australia are also favourable to that growth of fibre, and hence has been created, within a few years, a branch of trade most important to that colony. It has been often an object with English wool-growers, and landed proprietors, to produce this felting wool in England, and thus get rid of the necessity of purchasing abroad ; but it has been found impossible, after the most expensive expi?riments in im- porting sheep of particular flocks. It has been found that in two or three generations, even of the pure breed, the influ- ence of the climate and food totally changed the character of the wool, and brought it to the same quality as that of the native animals. It is thus evident that the manufacture of the native wools of Ireland can lead but to one department of that important branch of industry, that is. the worsted trade. With regard to wool- lens, this country, like England, must import wool, and hence will be under the same conditions of access to raw materials as the sister kingdom. In no degree are we less favourably placed. The Messrs. Willans, so extensively and so favourably known in Dublin, and who have also large factories at Leeds, have often and in public declared, that they carry on trade as 396 INDUSTRIAL RESOURCES favourably in Ireland as in England : the low price of coals in Yorkshire being fully counterbalanced by the cheapness of water-power, and a certain advantage in wages here. A substance which is the basis of more chemical manufac- tures than any other, is common salt. It yields chlorine, and is thus the original material of all the beautiful arts which in- volve bleaching processes. It yields soda, and this is an ingre- dient in soap, in glass, and numerous other substances not so universally kno^vn. In curing provisions, and as a manure, it is of extensive use, and as a condiment, it becomes a part of our daily food. There is, probably, no one material, the ab- straction of which would occasion so many deficiencies in the habits of a civilized people. Of this important substance, there is no natural deposit in Ireland. Salt is found usually in the new red sandstone, aud the gypseous marls which lie above the coal strata ; and thus about Chesshire are situated the great salt mines and pits of England, These formations exist in Ireland only in the north-eastern district, about Belfast, as described page 179, and they have not been found to contain any indications of salt mines. We are, therefore, dependant on England for our supply of this valuable material. Its price is so low, that the cost of transport increases its cost in a very important degree, and hence the various chemical manufac- tures, which require large quantities of salt, labour under a much greater proportional disadvantage in this country than the mechanical manufactures do, in regard to fuel, to produce steam. Salt, however, could be obtained, although not so economically, by the evaporation of sea-water. It is thus formed on the coast of Southern Europe ; the strong heat of the sun drying down the water, which is run into shallow re- servoirs. With us, the sun is not strong enough, and rain is too frequent to allow of such methods being adopted ; but by employing the plans that are actually adopted in Germany, to concentrate the waters of the weak bi'ine springs in those lo- calities, where there are no mines of rock salt, the sea-water of our coasts might be concentrated partially, perhaps to a half, and then the evaporation should be finished by means of coal OF IRELAND. 397 01' turf. It would occupy too long, and would, indeed, be su- perfluous, to describe those plans of evaporation. I shall only notice that the cost of the fuel that would be at least required to obtain a ton of salt, should be about 18s., and the other ex- penses would probably make the salt from sea-water cost, on the coast of Ireland, not less than 25s. per ton. The ordinary English salt seldom costs more in Liverpool than 10s. or 12s. per ton. Such are the conditions of these three important materials of industry, cotton, wool, and salt, as regards Ireland. We arrive now at the consideration of a most influential element in manufacturing calculations — the cost of labour, the lowness of which has been popularly considered as the most eminent inducement this country can present to the capitalist to em- bark in industrial undertakings. That human labour can be obtained in this country on lower terms than almost any other in Europe, is too well known to require examjjle. A population, for which the existing modes of cultivation do not supply occupation on the land, and which is not, as in the sister kingdom, drafted off to manufacturing employments in the towns, must, in order to live, accept of any terms of remuneration which they can get in exchange for labour. It is thus that 8d. or lOd. per day is found to be the usual rate of wages, at a distance from large towns, and that, even on such terms, thousands of men remain unemployed during the greater portion of the year : this nominal cheap- ness is, however, by no means necessarily economy in final cost. A wretched man who can earn, by his exertion, but 4s. or 3s. a week, on which to support his family and pay the rent of a sort of habitation, must be so ill fed, and depressed in mind, that to work, as a man should work, is beyond his power. Hence there are often seen about employments in this coimtry a number of hands, double what would be required to do the same work, in the same time, with British labourers. The latter would probably be paid at least twice as much money per day, but in the end the work woidd not cost the employer more ; although the wages, therefore, in the former 398 INDUSTRIAL RESOURCES example wero lowor, laboui' was not cheaper, on the oontrai'v, somewhat higher, as the trouble of overseeing twice the num- ber of men is a source of additional expense. When I say that the men thus employed, at low wages, do so much less real work, I do not moan that they inttmtionally idle, or that they reflect that as they receive so little they should give little value ; on the contrary, they do their best honestly to earn their wages, but supplied only with the lowest descriptions of food, and perhaps, in insufficient quantity, they have not the physical ability for labour, and being without any direct prospect of advancement, they are not excited by that laudable ambition to any display of superior energy. If the same men are placed in circumstances, where a field for increased exertion is ojoened to them, and they are made to understand, what at first they are rather incredulous about, that they will receive the full value of any increased labour they perform, they become new beings : the work they execute rises to the highest standard, and they earn as much money as the labourers of any other country ; wages are no longer low, but labom* is not, on that account, anything dearer than it had been before. An occurrence at a certain public work will exemplify this principle. Many hundreds of men were em- ployed at lOf/. per day. They worked slowly, and ineffectually; the work was not progressing, and as time was an object, a parcel of English labourers were introduced, who were paid Idd. per day, which they fully earned. None of the Irish la- bourers were dismissed, but they struck work, and demanded that all should have I8d. per day. The Englishmen feared for their lives. The police and military were called out, and the affair might have eventuated in a scene of blood, adding another to the tales of horror so industriously circulated about the savageness of the native Irish, At this moment one of the principal engineers, an Irishman, respected by the people for his abilities, and esteemed by them as a comitryman, came amongst them, and penetrating into the mass of excited la- bourers, arrested and gave into custody all the ringleaders. The crowd of labourers would not do him an injury. He then, in place of the common practice of saying they were OF IRELAND. 309 brutes, and none but English labourers were fit for any useful purpose, quietly explained to them that the Englishmen did much more work and deserved to be paid higher, but that ho would be very willing to secure 18(/. per day to every man, who would do as much work as the Englishmen, and more, if they could do more. He shewed them that from their rude way of managing their tools they wasted their strength, and that by simple improvements a great deal of time could be saved in their operations. The people knew and trusted him ; the police and military were withdrawn ; the whole body of labourers went to work, and after the first Saturday night they found, that without combination or violence, they could earn more money by laying themselves down steadily to do more work. After some weeks there were very few of the men earning less than 18c?., and many of them were earning at the rate of 2s. 6d. per day. In this case wages ceased to be low, precisely as the effi- ciency of work increased. The cheapness of labour is thus shewn to be quite different from the nominal rate of wages. This diiference is not peculiar to this country, it exists as forcibly in regard to certain countries of the Continent. Thus the iron manufacture in France is actually more retarded by this cause than by the greater proportional cost of fuel, which is popularly considered the most important. The manufactui'e of iron, including the extraction of the fuel, and of the iron ore and flux, as well as the actual smelt- ing and refining of the metal, occupies as many hands in France as it does in England, although the quantity of produce is not one-third so great. In fact, an iron work in Great ]jri- tain producing 10,000 tons of iron per annum, would employ 145 men, or a man for every sixty-nine tons of iron. In France it would require two furnaces for the same quantity of metal, and they would employ 445 men, or a man for every twenty- three tons. Hence, there are three times as many hands for the same work, and although provisions are so much cheaper and wages lower in France, more money must be paid to work- men there than in England to produce the same quantity of 400 INDUSTRIAL RESOURCES iron. In fact, in trades requiring consicleraV)]e mechanical skill, wages are actually lower in Englaud than in any other country, in consequence of there being so much more com- petition amongst persons so qualified. In every industrial occupation there are actually involved two totally distinct offices, which are paid for in very different de- grees. These are the animal force, and the mental exertion which directs it. The question of relative cheapness or dear- ness of labour altogether depends on the relative proportions we want of those, and the proportions in which they are pos- sessed by the man we hire. Now, owing to the general absence of industrial activity in this country, the mental power is not at all so universal as in Britain. It is hence dearer in Ireland, whilst animal force, destitute of industrial skill, being less abundant in Great Britain, is dearer there than it is with us. A bricklayer in London gets 22s. per week, and his labourer I4s. ; a bricklayer in Dublin gets 25s. per week, and his la- bourer but 9s. These proportions are often said to be caused by combination and threats against employers. It is not so ; the fact being that men who know how to set bricks are pro- portionally more abundant in London, and men who do not know how to do it are more abundant with us. This diversity produces both the power of combining, and the diffei'ence of wages. Considering man merely as a source of animal power, it is gratifying to have it proved, that when at all well fed, there is no race more perfectly developed, as to physical conforma- tion, than the inhabitants of this island. Professor Forbes in- stituted an extensive series of observations of the size and strength of the students attending the University of Edin- burgh, who may be considered as fairly representing the mid- dle classes of their respective countries; and I have subjoined the similar results of Professor Quetelet, regarding the stu- dents of the University of Bruxelles. The strength indicated is that shown by pulling out the stem of a spring dynamome- ter. OF IRELAND. 401 AVERAGE HEIGHT 1 AVERAGE WEIGHT IN INCHES. IN POUNDS. AVERAGE STRENGTH IN POUNDS.

In all operations, therefore, where brute force is required, there is no question but that we possess in Ireland, in the ac- tual population, a vast amount of power ; but the progress of art and of intelligence must lead us to consider such employ- ment as unsuited to a being endowed with the noble capacity for improvement that belongs to man. It should be his pre- rogative to subdue the greater strength of other animals, and to adapt the wondrous forces of external nature to his ends, by virtue of the intelligence with which he is provided, and the labouring force of man must be considered as lying truly dor- mant, so far as its true uses are concerned, until it be quickened by the energetic fire of industrial education. It is in this re- gard that Ireland is actually weakest, and that most difficulty may be expected in any i'uture development of our industry. No matter to what side we turn, or what problem of manu- facturing or agricultural improvement we proceed to, we find the difficulty of procuring skilled workmen or superintendents, and hence all such positions are occupii'd by natives of the 2d 402 INDUSTRIAL RESOURCES sister island, to the exclusion, as it would appear unfair, of the natives of this country. Such an idea is, however, quite unjust. Irishmen are not appointed to those situations because they are not educated for them. Scotchmen and Englishmen obtain them because they learn what is necessary for such duties. The remedy for this is not to declaim against intrud- ing foreigners, but to learn those trades so well as to make it the direct interest of the employer to give his countrymen the preference. Every intelligent Englishman or Scotchman who comes to Ireland should not be looked upon as an intruder, but as a schoolmaster. If there did not exist a blank in our in- dustrial system which it suits him to fill up, he would not come. He is a-head of us in practical skill and habits, and it should be our object to imitate him, learn from him, and, if possible, excel him, and when he finds that we know as much as he does, he will not come. He then would be better off at home. Skilled labour is thus shewn to be certainly dearer in this covmtry than in Great Britain, whilst unskilled labour is much cheaper. The final question of whether, for manufacturing industry in general, labour is cheaper here, is therefore not capable of receiving a decided answer. It must dejiend alto- gether on the proportions which the skilled and unskilled la- bour bear to each other. The total cost may actually be greater than in England. I am disposed, however, to con- clude, from tolerably numerous inquiries, that in most of the departments of manufactm-e, the balance is in favour of this country, and that the total cost of labour is so much less as to counteract many of the smaller advantages, as in fuel and freights, which the manufactm-er of the sister kingdom sliouhl otherwise possess. That, however, no such real difference in cost of effective labour here and in England exists, as is popu- larly thought, may, I trust, be considered as established by the foregoing evidence. A condition absolutely essential to industrial progress is freedom of labour. This freedom must be complete ; it must exist as regards master, as well as regards man. A work- man must have the most perfect liberty to place what value he OF IRELAND. 403 likes upon his labour. If he does not wish to work for certain wages, it is his affair ; and it were intolerable tyranny to con- trol his will ; but with that limit the right of the workman ceases. As he should not be controlled himself, he has no right to control others, and all interference of men to prevent their fellow-operatives from working below a certain rate, must be denounced as not merely contrary to existing law, but to the plainest principles of common sense, and utterly destruc- tive of the best interests of industry, not merely the interests of the employer, but, in an equal degree, of the men them- selves. It would lead me too far from my proper object, were I to enter upon this question, so important to be truly under- stood by the working classes. I shall, therefore, pass from considerations which should be but general in their applica- tions, and notice only one point in which the topic concerns this country. It is often asserted that an important obstacle to the intro- duction of manufactures into this country, is from the combi- nations which exist among the several branches of trade, and which subject the employer to laws and to restrictions so in- tolerable, as to prevent him from venturing amongst us. He, therefore, remains in England or in Scotland, where he is free to use his capital and machinery, to employ or not employ, as he thinks fit, and is not disturbed by clamour of combinators. To judge how far this cause can influence this country we must probe deeper than the surface. No person really conversant with the progress of industry in the two countries would assert that there is more combina- tion here than in Great Britain. The history of industry in England for the last century presents a series of the most violent outbreaks, riots, and combinations, murders of the most amiable employers, destruction of machinery and mills ; in fact, such an array of illegal interference with the just rights of property and labour, as would, if judiciously worked up by an active editor, supply materials for a history of Great Britain that has not yet been written. But these events are lost sight of by the public in the vast extent of British indus- try. The ringleaders are punished ; the general mass roturn 2d 2 404 INDUSTRIAL RESOURCES to their work ; in no case has the object of tlie strike been at all successful, for the unfortunate artisans seeking to enforce from particular localities or employers what the general pro- gress of industrial discovery opposes, must yield before the movement of the age, and by warring against, in place of moulding themselves to it, suffer too often under its evils, without being able to participate in its good. In this country, however, cases of combination derive an ex- trinsic imjjortance from causes quite independent of their true nature. Our industry is so limited in amount, that a disagree- ment, which in England would never be heard of, except by those immediately concerned, becomes a topic of universal comment, and, unfortunately, the organs of public opinion are too often hurried by the eagerness of political feeling into speak- ing of a quarrel between an employer and a few men, as if it were a general outbreak of the working against the employing classes. Thus some time ago a sugar bakery was erected in Cork, and the proprietor very prop rly brought over from England bricklayers conversant with the modes of setting the pans and other apparatus. For the rough work, to which only they were really competent, Irish bricklayers were employed, but these, finding that the Englishmen worked for lower wages than the Cork standard, refused to work with them. In this they were perfectly justified. The Irish bricklayers had a clear right to leave work and stay idle, if they preferred it to earning money. But they went further, and demanded that the English bricklayers should be dismissed, and that none but the workmen at high rates of wages should be employed. Here they were totally in the wrong, and the proprietor very pro- perly refused to comply. The idle workmen stood about the gaces for a few days; their wives favoured the proprietor with a course of Munster billingsgate; but the intervention of a few policemen restored order, and the matter was really so unim- portant that in a week it was forgotten in Cork. But it was not forgotten elsewhere. The journals took it up, and concealing that the whole affair was a dispute about working for wagi;s under the ordinary rate, they seized on the question of English and Irish, and poured out on the poor OF IRELAND. 405 ignorant Cork workmen and their unhappy country, column after column of vulgar abuse and contumely. We were sa- vages, brutal rioters ; the whole was but one indication of the hatred we bear to Englishmen ; of the stupid obstinacy with which our barbarism repels the introduction of intelligence and civilization from the sister kingdom : and not only were such absurdities printed by the most eminent daily press, but the articles were reprinted in works pretending to be purely statistical, and it was inferred, that Ireland is in a state of social barbarism ; that if mills were erected they would be burned ; if masters gave employment their throats would be cut ; that the means of earning wholsome food and healthful habitations, of dressing comfortably, and educating their children to useful trades, are looked upon in Ii'eland as ob- jects sedulously to be avoided; that tlie native Irish have an in- domitable and natural taste for rags and dirt, for sloth and hunger, for violence and murder. We can afford to laugh at such tirades now. After all the schoolmaster is abroad. Besides the fact of the importance of such strikes being magnified by the imwholesome appetite for political excitement which pervades this country, there is another, perhaps still more influential in its operation upon trade. Employers are in Ireland much less able to stand out against strikes than in the sister kingdom. They possess less capital ; its rapid cir- culation is a matter of more pressing necessity, and hence any temporary interruption is more felt. But still more important is the circumstance, that in Ireland, employers are more de- pendent on their men, than those of the same class in England. They do not in general know their own trade as well. If an English workman refuse to do a piece of work, the master can, if he chooses, do it himself, and this gives the employer a moral superiority and power, which the Irish manufacturer, in too many cases, does not possess. To tliis there are, I am aware, many and brilliant exceptions, and these exceptions are the more important, as their success, well merited by their energy and industrial knowledge, becomes a beacon to others on the same track. In every case that I have known of, in this country, where the master shewed himself possessed of the really high 406 INDUSTRIAL RESOURCES qualities, which the direction of extensive industry requires, combination has been unknown, or, if attempted, has eventuated in the establishment of the employer, and of his trade, in a better condition than before. There is but one remedy for combination ; education. Not merely intellectual education ; not merely to brighten up the faculties of a man, as you polish and smooth the parts of a machine, that it may do more work, and with less friction : but that education which developea equally the moral and in- tellectual mind. And this education is as much required for the employer, as for the employed. If knowledge alone be o-iven, it will confer power ; whoever knows most must ulti- mately command, be he master or man, and if his morality be low, he will oppress ; he will insist upon rights, and neglect his duties. Educate, therefore, the moral faculties of all classes. There may thus be generated what is more than all else wanted to give happiness, tranquillity, and wealth to Ireland, a sympathy between the higher and lower classes, a sense of their mutual dependence, and mutual duties, a pleasure in the re- cognition of each other's joys, and reciprocal condolence in those sorrows which fall to the lot of every rank. Manufac- turers, otherwise well informed, have said, " what have I to do with my workmen, but to receive their labour and pay them for it? 1 have no connexion with them once they leave the factory ?" That is not right. Is it nothing to the employer whether his workmen spend their evenings happily with their families, or in drunkenness, in gambling, or perhaps theft ? Which would be most likely to make honest servants, and steady workmen? Which would be most likely to prevent an attempt to destroy his propei-ty, or perhaps his life? There can be but one answer. Independent of moral grounds, the kindness, sympathy, and attention of an employer to his work- men, is the safest and most profitable money speculation in which he can engage. So far from the habits of the working classes of this country being adverse to the introduction of industrial occupations, they have made, within the last few years, unparalleled strides in the habits which best conduce to industrial success. I do OF IRELAND. 407 not hesitate to assert, that the existing generation in this country is half a century in advance of that which is dying off, and that the generation now at school will be a century in ad- vance of us. We were reckless, ignorant, improvident, drunken, and idle. We were idle, for we had nothing to do ; we were reckless, for we had no hope ; we were ignorant, for learning was denied us ; we were improvident, for we had no future ; we were drunken, for we sought to forget our misery. That time has passed away for ever. In Ovoca, on pay days, where 2000 men are employed, 500 gallons of whiskey used to be bought by the miners, and drunk upon the works. The men spent the night in fighting, whilst their wives and children begged in vain that some of their wages should go for provisions and for clothing. There is now upon pay days no whiskey whatsoever sold. The wives of the workmen receive their wages for them, and quarrelling is unknown. Some years ago, the village of Bonmahon presented, on pay days, a scene of strife and drunkenness, which always required the intervention of the police, and often rendered the position of the superintendants dangerous. At present nothing of the kind is kno^vn, a temperance hall for social quiet meetings, and extensive school rooms for the education of the children, are now built, and the same number of individuals are able to earn £300 per month more than they formerly received, by the greater steadiness and attention to their work, which accom- pany their improved domestic habits. I might adduce a great nimiber of such examples, but it is not required. The children are at school ; the parents are sober and steady. The revenue collected on ardent spirits has been diminished to one-half; notwithstanding that the export trade has augmented. The sums in the Savings Banks are not ma- terially augmented yet, and it is better not ; the mere desire to amass money is, after all, not what we want most. Greater desire to live comfortably, to eat of better food, to live in bet- ter houses, to wear superior clothing, to buy good books, these are passions far more useful to the people, a^d more important to encourage, than the mere accumulation of money, which there 408 INDUSTRIAL RESOURCES is no danger will come, if it be not already present, and wil] lead to its usual results. Labour, as it exists in Ireland, if it be unskilled, is thus now in the best possible condition for receiving the impulse of skilled direction. It becomes, hence, vitally important to pro- vide for the proper direction of the nascent energies of the people. We have passed the line which separates progress from inactivity. May our future course be guided by intelli- gence and morality. There is another circumstance, so popularly counted on ps a most material obstacle to the development of industry in Ireland, that I cannot leave the subject without briefly ad- verting to it, that is the want of capital. This has been the bugbear of Irish enterprize for many years. England has capital, Ireland has not ; therefore England is rich and in- dustrious, and Ireland is poor and idle. But where was the capital when England began to grow rich ? It was the in- dustry that made the capital, not the capital the industry. An idle or ignorant man will lose his capital where an active and intelligent man will create a capital. We leave our fields in barrenness, our mines unsought, our powers of motion unapplied, waiting for English capital. Labour is capital ; intelligence is capital ; combine them and you more than double your amount of capital. With such capital England commenced, as Ireland must commence, and once that we have begun and are in earnest, there will be no lack of money ca- pital at our disposal. The subject must, however, be more numerically stated. So far from being unable to extend our industry for want of capi- tal, we do not employ the capital we have in active industry. When money is made in England it is re-invested in the same or in a similar branch, concerns are increased, and transac- tions multiplied, until the amount of capital attains the vast dimensions which we now see. If some money be made in trade in Ireland, it is not so treated, it is withdrawn from trade, and stock is bought, or land is bought, yielding only a small return, but one with the advantage of not requiring intense exertion or intelligence, and free from serious risk. Ca- OF IKELAND. 409 pital cannot, therefore, increase with a rapidity at all com- mensurate with English progress ; but that capital of great amount does truly exist in Ireland available for industrial uses, if the owners had a taste therefor, is certain. More than two millions of Irish capital is transferred every year to Englan d in purchase of English Government stock. Many^ of th e &ig- lish railways have a nume rous Iri sh proprietar y. The property in steam vessels belonging to Dublin is only exceeded in amount by that of London, and is actually greater than the united steam property of Bristol, Hull, and Liverpool. With such facts, it is useless to say we have no capital ; we do not want t he capital so much a s we do the know ledge and disposition to employ it. Let it not be supposed I object to English capital ; on the contrary, money is too good a thing to refuse, and especially from our dear sister, who has got abundance of our money on much better terms than she is likely ever to give any of her's. But I do not think that English capital will be employed in the direct advancement of our manufactures or agriculture, al- though it certainly will, indirectly, and thus be of immense ser- vice to us. But suppose an Englishman possessed of £50,000, and wishing to invest it in spinning cotton : he has his choice to go to Manchester or Killaloe. In the former place, he has coals cheap, workmen of every class at hand, machinery made at his door, market established, and if he wants to sell in Ire- land he has canal and railway to Liverpool, thence steam to Dub- lin, and canals then to the Shannon. If he comes to Killaloe, he has to bring his machinery, and all his higher workmen, to bring cotton, and to settle amongst a people concerning whom his ears have been stuffed with newspaper stories, some unfor- tunately true, but mostly false. His sympathies are at his home, and unless profits were considerably higher, he should remain at home, and such would certainly be his course. Now profits cannot be sensibly higher in Ireland than in England. There is, therefore, no inducement for him to come. Take woollens, or any other branch, in place of cotton, and, by a similar chain of facts, we shall be led to the same conclusion. But some English capitalists have settled amongst us, it L 410 INDUSTRIAL RESOURCES may be said, and hence the above reasoning cannot be abso- lute. There are some, as the Willans, who have cloth mills here and in Leeds, but they settled here at a time, when, by a system of differential duties, trade between England and this country was impeded, and to which it would be a most bar- barous retrocession in industrial economy to think of returning. They have not dismantled their factory, because cloth can be made as cheap with us, but they have not materially extended, because cloth is as easily brought from Leeds. English capi- talists will establish factories in France, Austria, and Belgium, because the tariffs of these countries secure them higher re- turns than English competition allows. They are paid higher as schoolmasters for the natives. This country does not afford such advantages, and hence we cannot expect them to come. To this there may be individual exceptions, arising from pecu- liar instances of enterprize, but this does not affect the ques- tion as regards the country generally. For active industry, English capital cannot be expected, and if it do revive, it must be by Irishmen and Irish capital. English capital may, and, I have no doubt, will, be highly useful in the operations of what I may term passive industry; in the creation of the various collateral aids to commercial business. If an English capitalist have a few thousand pounds to invest in shares, he will as soon put it into an Irish railway or a canal as into an English one, if it promise the same re- turns. Hence the vast accumulation of money of the sister kingdom may be most usefully employed in rendering our rivers navigable, in completing our water intercourse by canals, in constructing our lines of railway, and thus, whilst it brings to the owner at least as must profit as it should do if laid out in England, it will prevent such works from absorbing the ca- pital of Irishmen; who, on the spot, and familiar with the people, if they were properly acquainted with the structure and capabilities of the country, and thoroughly educated in their trades, might apply their individual capitals to the creation of active industry. By means of English capital also, agricultural industry may be, and is in progress of important amelioration. The owners of land were very generally loaded with monetary OF IRELAND. 41 1 obligations incurred at a high rate of interest, which are now being rapidly removed by means of loans from England, at moderate charges ; the estates thus freed will enable their pro- prietors to devote more money, and, it is to be hoped, intel- ligence, to their improvement, and therewith the improvement of the people. The large amount of Ii'ish capital thus liberated from the land, will become available for active industry, and must, indeed, bfe very energetically employed to produce the equivalent of what had been received. Acting in this way the sister kingdom may be most useful and most powerful in advancing the industrial condition of this country ; it will be profitable, and, therefore, she will finally do it. The investment of English capital and of Irish enter- prize must, however, go hand in hand. The railway is of no use unless there be a suitable increase of traffic. The means of transport are not wanted f there be not products of industry to convey. English capital, therefore, even where it might be most useful, may totally fail in its object, and its invest- ments give no profit, imless the morals of the people, their taste for industrial pursuits, and their education, be promoted wdth the utmost zeal. Numerous companies have been, from time to time, formed in England, for the purpose of developing some branches of the industrial resources of Ireland, especially our mines. They have been almost universally failm*es, and Ireland, as a field of enterprize, has been hence at a discount in the English market. It is not difficult to see why they failed ; the causes were ignorance of the country, and want of economy. Thus, to work a coal mine in Ireland, an overseer and miners are employed, who know perfectly how coals are worked at New- castle, and who bring over steam engines and gins, on a scale proportionate to the English beds, but totally unfitted for the localities of our coal fields ; the natural disadvantages are heightened by the want of adaptation on the part of the sys- tem pursued ; the overseer is not himself vitally interested, his employers are at a distance, and under such circumstances it need not be a matter of wonder that the concern does not pay. 412 INDUSTRIAL RESOURCES It is thus shewn, that many of those conditions, as dearness of fuel and want of capital, to which is popularly attributed the absence of extended industry in this country, are, in reality, by no means so powerful, and in fact do not present obstacles to our progress greater than what are every year surmounted in other places ; on the other band, we find, in the abundance and economy of water power, in the extent of our mines, and the fertility of our soil, in the capabilities of our rivers and harbours for water transport, and of the general surface of the country for land carriage, so many circumstances in an unusual degree favourable, and leading to the most sanguine expecta- tions of the results of industrial enterprize. To what then is it due that we have made so little way ? Why is it that our people are unemployed, or are driven to seek the means of living by periodical emigrations to fulfil the lowest offices in another land ? AVhy is it that our harbours are bare of ships, our rivers undisturbed by the bustle of industry and inter- course, our fields producing but a third of what they might supply ? that where activity exists, or that progress is now being made, it is to be traced, with but few exceptions, to the introduction of the natives of the sister kingdom, into whose possession there thus pass the most valuable domains of enter- prize which this country offers, whilst the Irish population rests in the lowest grade, and but rarely manifest the quali- ties which the time requires. The fault is not in the country, but in ourselves ; the ab- sence of successful enterprize is owing to the fact, that we do not know how to succeed ; we do not want activity, we are not deficient in mental power, but we want special industrial knowledge. England, which in absolute education and in general morality is below us, notwithstanding our criminal violence, is far above us in industrial knowledge. The man who knows not how to read or write, who has never been at clmrch, who never taught his child to reverence the name of his Creator, will be a perfect master of his trade. The ma- chines he constructs, or the products he elaborates, will be most perfect in their parts, most suited to their purpose, and most economical in their cost ; from the task which he under- OF IRELAND. 413 takes nothing will turn him aside ; he knows that time as well as labour is required for an industrial result ; he invests his time as he invests his money, as regularly and as extensively ; his steadiness and perseverance in his pursuits are thus part of his industrial knowledge ; his acquaintance with the pro- babilities of his trade prepares him for difficulties, and hence enables him to surmount them. Such things, he knows, must be in ordinary course, and thus he works constantly on, through alternations of success and failure, to his final triumph. In this industrial knowledge we are deficient. An Irishman takes up a branch of trade ; after a time he finds it requires more capital than he expected, and he becomes involved. He finds that the profits are less than he had hoped, or he discovers that foralongtimehecan make no profit, and he is discouraged. Circumstances arise which he is not prepared to meet; the conditions of the branch of industry may have changed since he first entered into it, and finally he loses, perhaps, all that he had embarked in trade, simply because he did not know his trade well enough. An eminent Belgian minister, M. Briavionne, having occasion to describe the importance of attending to the education of the working and commercial classes in that coun- try, drew his examples of the consequences of neglect, and of attention to it, from the existing position of the British Is- lands. He asks: " What has produced the difference between the rich and flourishing condition of England, and the poverty and weakness of Ireland? Industrial knowledge." He stre- nuously urges on the Belgian legislature the necessity of at- tending to industrial education, lest Belgium should become like Ireland. The education necessary for industrial pursuits is very ge- nerally underrated in this country, and from this cause alone springs a great deal of our want of industrial knowledge. Our ignorance is so great, that we are even Incapable of estimat- ing its extent. If a boy is to be sent to a profession, great care is taken with his education. Literature and science pre- sent themselves to him hand in hand. A reputation, the best passport to professional success, may, it is said, be founded on school and college character, and his ambition is excited by 414 INDUSTRIAL RESOURCES the social and political eminences which professional men may attain. But if he is going to trade, education, it is thought, would be thrown away on him. If he can read and write and cypher, it is supposed to be enough. Should an ambitious parent desire to give his son a good education, although he is to be in trade, he puts him through college. He devotes the best years of his youth to reading Grecian poetry, and Latin plays ; to learning by rote the dialectics of the middle ages, and principles of abstract metaphysics, and awakens, after the so- lemnity of getting his degree, to find that he is to obtain his living by principles and pursuits to which his education has had no reference whatsoever. He finds that the safety of his property may depend on the navigation of a sea, of which he never heard whilst labouring for months to understand the geo- graphy of the Odyssey ; that the mode of growth, or the che- mical composition of a plant, of whose existence neither Greek nor Roman knew, may be the means of gaining or of losing fortune, and of it he has been left in ignorance ; that his daily commercial intercoiu'se is with men and nations, of whose lan- guages and whose customs he is totally ignorant, whilst he has spent his youth in learning how he should have spoken had he lived three thousand years ago. It is very well for those, who, independent in fortune, and devoted rather to ease than enterprize, wish to dream through an existence which offers to them but roses they did not plant, to seek in the literature of past ages, an elegant and innocent occupation. Indeed, to all classes the literature of present and of former times, of our own and of foreign coimtries, presents a relief from the weary continuity of action, which industrial pro- gress requires. To the man of business, there can be no en- joyment greater than to transport himself from the anxieties of the desk or factory, to communion with the best lessons, which human intelligence has handed down, or to obtain, within a few volumes, the records of the greatest deeds, the noblest struggles, and the holiest thoughts which have been allowed to man. But this is not his business. This knowledge is not that by which he is to live, and the first object of one depen- dent on his own exertions must be to learn to employ them, to OF IRELAND. 415 educate his faculties specially with regard to their future iise in the development and the improvement of every part of what- soever line of business he embarks in. The idea of there being no direct connexion between trade and education, has derived support, with many persons, from the examples of individuals, highly educated, failing entirely when they engaged in trade, whilst other men, of no education whatsoever, have been brilliantly successfid in industry. This argument is, however, when analysed, strong on the other side. What is called education by those persons, is not so, it is, on the contrary, worse than no education whatsoever. If a man knows Greek and Latiu, if he can expound all the niceties of metaphysics, what does it avail him when he proceeds to spinning cotton, or to smelting iron ; quite the reverse. His habits and modes of thought are at every moment shocked by the rough clashing of the realities on which his fate depends. His mind, accustomed to discussions, which, whether right or wrong, leave life as it has been before, becomes appalled at the stern calculations of a problem, in which his liberty, his home, his fortune is involved. The man is not able for his position, and he fails ; but he fails not because he was an educated man, but because he was not educated for his trade. On the other hand, who are those uneducated men that suc- ceed in trade ? A yoimg man, wanting to sell spectacles in London, petitions the Corporation to allow him to open a little shop without paying the heavy fees of freedom. He is refused. He goes to Glasgow, and the Corporation refuse him there. He makes acquaintance with some members of the University, who find him very intelligent, and permit him to open his shop within their walls. He does not sell spectacles and magic lanterns enough to occupy his time ; he occupies himself at intervals in taking asunder and remaking all the machines he can come at. He finds there are books on mechanics written in foreign languages ; he borrows a dictionary, and learns those languages to read those books. The University people wonder at him, and are fond of dropping into his little room, in the evenings, to tell him what they are doing, and to look at the 416 INDUSTRIAL RESOURCES queer instruments he constructs. A machine in the University collection wants repairing, and he is employed. He maices it a new machine. The steam engine is constructed, and the giant mind of Watt stands out before the world, the author of the industrial supremacy of his country, the herald of a new force of civilization. But was Watt educated? Where was he edu- cated? At his own work-shop, and in the best manner. Watt learned Latin, when he wanted it for his business. He learned French and German ; but these things were tools, not ends. He used them to promote his engineering plans, as he used lathes and levers. Arkwright began his career a barber ; he had a taste for mechanical combinations, and spent all he could save by cutting hair, in putting together wheels and levers, making little ma- chines, which sometimes answered his purpose, and sometimes not. At last, he put them together after a manner which has led to momentous consequences. He invented, or at least he rendered practicable, the spinning by rollers, and created the basis of the cotton trade in England. Was he not educated ? Did he not educate himself, whilst carrying his wigs and barber's apparatus from house to house, thinking about his models of machines, and so wrapt up in them, that his wife, in a passion, burned them all, for which he removed from her, and stipulated that she should let him invent in quiet. He was not as great a man as Watt. His education did not go so far, but it was his real industrial education which made him the founder of a vast manufacturing art, and enabled him to be- come one of the wealthiest subjects of Great Britain. Tracing the history of men successful in a less prominent degree than Watt and Arkwright, we are led to the same re- sult. Their success is proportional to the conjoint action of their mental power and knowledge. That knowledge is often difficult to acquire. So far from industrial pursuits not re- quiring education, they do require it in much greater degree than any of the so-called professions. Industrial knowledge is much more difficult to acquire, and much more extensive in its range, than professional knowledge ; and yet, in Ireland, its acquisition has not been attended to in any efficient degree, bF IRELAND. 417 nor have the general principles, upon which its communication should be foimded, been at all generally understood. Every department of agricultural and of manufacturing in- dustry has its origin in scientific principles, practically applied. The weaving of a woollen cloth, the rolling of an iron rail, or of a brass ornament, the construction of a clock, the prepara- tion of soap, or of oil of vitriol, all require the discovery of a certain principle, which, working by a certain process on cer- tain materials, elaborates the product. Sometimes a process, with particular materials, is hit upon long before the principle of its action becomes known, and the art exists, but cannot extend itself, for with any other materials, the process cannot answer, whilst with any other process, the materials are not suited ; and hence, although the art may arrive in that limited form to great perfection, it is impossible to transplant it to other places or into other hands. On the other side, a scien- tific principle may be discovered, and yet remain long barren of practical results. Science and art, which should distribute, by progressing hand in hand, the highest blessings of industry and civilization, are thus often separated, and the more so, that the persons by whom each is cultivated are kept asunder by the false ideas as to what really constitutes education. The man of science, occupying himself with the interesting paths of abstract discovery, thinks not of community of objects, or of feeling, with the dark, coarse-handed operatives, who, in the furnace or the forge, work up the really practicable solu- tion of his problems ; whilst the worker, equally ignorant of the importance of bringing together their respective modes of ex- periment and inquiry, considers science, like the dead languages, as characterizing the position of the upper classes, from whom, intellectually as well as socially, he keeps apart. The real fact is, that only of late years has science at- tained a position of such accuracy and power as that it could efficiently come to the assistance of the arts in devising new methods, or in suggesting the use of new materials. The phenomena of a manufacturing process are so complex, are so affected by little details of working, by temperature, by mois- ture, by presence or absence of air, by mechanical conditions, 2e 418 INDUSTRIAL RESOURCES and by molecular forces, that the problems were really too complex and difficult for science, in its existing state, to grap- ple with ; and, in most cases, a process was brought to prac- tical perfection, not by the direct advice of a man of science, but by the continued working of a number of practical men, who, at great expense, intense labour, and numerous trials, brought it to succeed. The man of science may then be able to tell him why it succeeds ; but the artizan is often tempted to say, that he is not particular as to why, provided it does succeed, and he is disposed to consider as imnecessary, and practically inapplicable, that scientific knowledge which alone ordinary scientific men can supply. The artizan is, however, as much in error in neglecting ab- stract theory as the philosopher in regarding practical results distinct from science. When theory teaches us what is really essential in a process, it enables us often to simplify that pro- cess and to render its working more economic ; or it may ena- ble us to modify it so, as to carry it on in other places, where the materials originally necessary could not be had. It is thus, that even where the practice of the art has preceded theory, the latter facilitates the extension and improvement of the art. But such cases are much less numerous than is really thought. He who devises a process has almost universally a theory, and the only difference is, that if the theory be wrong, he stumbles in the dark, until, by long continued practice, he works rightly in spite of his theory, whereas, if he had kno^vn the true theory, he would have lighted upon the proper practice in the begin- ning. In every great improvement that has been effected in the arts, a distinct idea of the object and of the means of effect- ing it, that is, a scientific theory, has been first conceived. Watt had the idea of the steam engine distinct in his mind be- fore he ever made an engine. Under these circumstances, it is evidently of the greatest consequence to render the theore- tical ideas of the practical worker and inventor, as distinct and exact as possible, that is, to superadd upon his al ady practical education, so much acquaintance with science, as may enable him fully to understand the properties of the sub- OF IRELAND. 419 stances upon which he operates, and the laws of action to which they are subjected. To give an industrial education, therefore, it is necessary to unite the two elements — science and practice. Science should be taught especially with a view to the application of its prin- ciples. Practice should be followed with constant reference to the principles upon which it rests. In this way, the elements of the highest industrial progress should be obtained. The economy of any process, the effective duty of any machine, the real value of any material, would be tested by the application of direct calculation to the results produced. The manufac- turer never could be taken by surprise, for the different ope- rations of his works would all be conducted under a system of numerical control, which should render it impossible that any- thing important could escape his observation. The practice of the arts is that which is most diftlcult to be learned, and that in which we labour under the greatest disad- vantage. In England, every manufacturing town is a great school of practical education, where each branch of mechanical and chemical industry is carried on, on a vast scale, and by a variety of processes. Her workmen, thus educated, though otherwise illiterate, pass into other countries, and are thus serving, most efficiently, to develope throughout Em-ope the different branches of native industry. Amongst us, such schools of industrial education, are, as yet, scarcely existant. For the acquisition of this practical knowledge, we must look therefore to Manchester, Leeds, and Birmingham. These are the uni- versities, in which the persons desirous of developing the in- dustrial resources of Ireland must graduate. The English workmen, although perfect in thus carrying out the processes to which long experience has conducted them, are destitute, owing to the low state of general education in that country, of the power of applying the aids of science to their modification, or further improvement. The processes adapted to the nature of materials in certain districts of England, are inapplicable in others, and still more in other countries, and it is on this ac- count that so many schemes for utilizing our sources of indus- try have failed totally in the hands of the English workmen 2e 2 420 INDUSTRIAL RESOURCES imported to carry them out ; because they found themselves under new circumstances, and with materials which differed from what they had been used to, and did not know the prin- ciples of their trade at all sufficiently to enable them to intro- duce proper modifications. A person about to be educated for industrial purposes should, therefore, be first thoroughly grounded in the general princi- ples of the natural and physical sciences, and in elementary ma- thematics. All this can be done with far less expenditure of time, of trouble, and of money, than is usually incurred with the Greek and Latin, for which, in industrial pursuits, there is sel- dom the slightest use. Thus grounded in general education, he should pass to his special branch, according as he is to be a chemist, a maker of machines, a worker in metals, or of other trade. Of all the objects used in his peculiar occupation he should acquire the most minute knowledge; their properties and composition ; their adulterations ; where they are found ; how they are obtained ; what can be substituted for them ; how they can be made. All these are things on which may depend, at each step of his future progress, whether he follows a losing trade, or whether he be eminently successful. To this general education should be added the experience of the workshop. The simplest operation in the arts requires a degree of manipulative skill that no books, no words can give. The most perfect theoretical acquaintance with the construc- tion of machines and the nature of various materials used would not enable a man to do good work. But if the man has obtained the manual skill by working practice, there is no doubt but that the knowledge of the tools he is using and of the mate- rials he works upon, will enable him to do it better than he otherwise could. The practical education of the artizan in the place of actual working is, therefore, of all the most im- portant, and requires most time. The ultimate object of the previous discipline in science is to enable him fully to avail himself of the opportunities of improvement in his art which the workshop continually affords. This subject of industrial education is, as it appears to me, specially important to this country, as without it any available OF IRELAND. 421 development of our industrial resoui'ces must be almost impos- sible. In every branch of manufacture England is already in possession of the field, and if we only learn from her, and are competent merely to follovt^ her routine processes, we must re- main alvFays behind in the march of industrial improvement. There is no physical disadvantage in this coimtry to render it necessary that we should always remain destitute of manufac- tures as we are at present. But we certainly do not possess any advantage over England. On the contrary, her charac- ter is already made ; her mechanism is already in operation. To keep a market does not require at all as much exertion as to obtain one ; and hence it is only by the most strenuous ex- ertion, and by the most perfect knowledge of his trade, that an Irish manufacturer can have any chance of success. To suc- ceed against his English competitor, he must know more than him. It is evident that we have much to change, yet it is not impossible. The practical part of education for industry must be effected in the factory. But all that part which consists in general and special scientific discipline might be most efficiently carried on by means of institutions of a collegiate character. The central School of Arts and Manufactures in Paris, foimded under the direction of Professor Dumas, deserves, in this point of view, to be considered as affording an excellent example. In Prussia and Austria similar institutions have been organized imder the care of the government ; and in England and Scotland also the necessity of adding scientific knowledge to practical education has been acknowledged by the foundation of de- partments for that purpose in connexion vnth various local institutions. A century ago, long before the necessity of connecting sci- entific knowledge vnth the arts was felt elsewhere, an associa- tion was founded in this country expressly for that purpose. The Dublin Society, whose exertions in the advancement of husbandry and the other useful arts were so eloquently de- scribed by Arthur Young, and admitted by him to be the origin of all the similar societies in England, has, from that period to the present, undeviatingly promoted the objects for which it 422 INDUSTRIAL KKSOURCES was founded. The liberality of the government of that time placed at its disposal great sums of money, which were applied to the prosecution of various plans conceived to be advan- tageous to the country. That it effected vast good is undeni- able. But at that period it was too much in advance of the o-eneral population for its beneficial power to come fully into play. The country was not ready for an extensive industrial movement. Since that time its funds have been progressively diminished ; its departments necessarily curtailed ; its scientific and industrial organization limited in extent and still more in powers. But there appears some hope that the darkness which overhung those days is about to dissipate, and that the Royal Dublin Society may be enabled agaiu to become the centre of industrial education for this country. Its means of effecting good, were it supported by anything like the sum to which this country is entitled for such objects, are very great : — its fine Botanic Garden, in which all expe- riments regarding agriculture might be so efficiently put in ac- tion; its Museums of Agriculture, and for Natural History, as well as for all industrial products and materials ; the re- sources of its extensive Laboratory, in which investigations calculated to smooth down the many difficulties which beset the path of enterprize in Ireland might be so well conducted ; its almost continuous courses of lectures on every branch of applied science, and the means recently placed at its disposal of having similar courses of lectures delivered in provincial towns ; the triennial exhibitions of manufactures, the annual cattle shows, in which the progress of our artizans and agri- culturists may be registered, and rewards stimulating them to honourable ambition may be distributed; and, finally, the Schools of Art, which, although not exclusively connected with industrial objects, are yet most powerful adjuncts thereto, by enabling the manufacturer to bring to bear upon the improve- ment of certain branches of trade, aforceof fancy and cultivated taste that not only may be, but has been found most conducive to success. With such facilities for communicating all that general scientific education which I have described as the basi.s of sound industrial knowledge, the Royal Dublin Society may OF IRELAND, 423 be the source of important advantages to Ireland. It is not now, as half a century ago, when its members were so far before their age, and were so separated from the general population, that their plans of improvement, their premiums, and their bounties, falling upon a soil unprepared by previous workings for the reception of the seed of energy and science, yielded not a commensurate return. The people now are competent to work out the precepts W the* Society. The Society has be- fore it the noble task of giving to the people such precepts and example as may draw forth the slumbering energies of Ireland, and create employment, with its constant attendants, comfort and tranquillity. To the middle classes of Ireland, to whom specially the in- dustrial fortunes of the country must be committed, the Royal Dublin Society should become the source of scientific education. It belongs to the middle classes : not to any section or subdi- vision of the people, but to Ireland. Its objects are truly Irish. Its office is not to perpetuate the middle age absurdity of an exclusive university, but to explain to all the modes by which we may become more learned in om* respective trades ; more skilled in all the processes by which we have to support our families ; how we may become more intelligent and more wealthy, and hence inevitably more powerful and more re- spected. It deserves fully the sympathy and co-operation of every Irishman. In discussing the general question of the relations of scientific knowledge to the pursuits of industry, I have spoken of industry more as regards manufactures than agriculture, because it sim- plified, in a corresponding degree, the conditions of the ques- tion, and enabled me to treat of it more briefly. Every argument proving the necessity of knowledge to the manufacturer, applies however, equally to the agriculturist ; and, as in the existing circumstances of Ireland, manufacturing industry can only come into play by slow degrees, it is by improvements in agriculture, for which education is absolutely necessary, that the most rapid and most extensive amelioration in the condition of the people must be effected. Agricultural education is, therefore, the object on which immediate attention should be concentrated in 424 INDUSTRIAL RESOURCES this country. It should, like other industrial education, con- sist of the general scientific discipline which has been already described, and be perfected by the practical education of a well conducted farm. For the commencement of this education, the- arrangements of the Royal Dublin Society are eminently adapted, and the co-operation of the Royal Agricultural Society, which embodies almost every landed interest in Ireland, will be a most powerful stimulus to those who have to live by agricul- ture, to avail themselves of such means of increased knowledge. The practical education of the farmer or land-steward can be completed in those schools, of which so many are now in opera- tion, or about being formed, as at Templemoyle and Lough- Ashe. That contemplated on a larger scale, at Leopardstown, cannot fail, if carried out upon a proper plan, to be of great utility. We will hear no more of the superiority of Scotch farming, or of the exclusive employment of Scotch stewards, if Irishmen set themselves about learning their trade as well, and fit themselves, by steadiness and practical knowledge, for such situations. That these views are in no material degree unsound, is fully shewn by the fact, that the Commissioners of Education have, in organizing the plan of instruction for the poorer classes, always considered industrial education as a necessary element of their system. What can be of higher beneficence to a popu- lation, than the instruction of the child in the general princi- ples of the trades, by one or other of which the man will have to support a family. This object, however, could not be fully carried out by the means hitherto available ; and hence the Commissioners have, for reasons such as are described above, concentrated their eiforts upon agricultural education. Even in this, their plans cannot be yet fully brought into play. The schoolmasters have to learn the principles of agriculture, be- fore they can teach them ; and this education of the educators, is the step now in process of working out. The scientific lec- tures, by eminently qualified teachers ; the practical workings on the model farm, landcr the directions of a highly skilful agriculturist, will, after a little, enable the Commissioners of Education to settle in each parish a schoolmaster, who will be OF IRELAND. 425 also a minister of industrial progress, and by whose precepts and example, the seed of practical intelligence shall be culti- vated, and return hundred fold. "With such a system of edu- cation, and with the habits of temperance, of moral conduct, and fixity of purpose, which, it is acknowledged, are growing rapidly upon the Irish character, there is no fear for the work- ing classes. It is the middle classes that have most difficulties to overcome, most bad habits to break from. I have endea- voured to indicate to them at once the sources of material pros- perity, which the country possesses, and the means by which alone, as I conceive, they can acquire the power of properly utilizing them. I have been asked, whilst engaged in the consideration of this subject, " Would you seek to introduce into Ireland that manufacturing system, which, whilst creating vast wealth for a fortunate few, throws the majority of the population into a state of moral and physical wretchedness and destitution, to which there is, absolutely, no parallel in this country ?" The Reports of the Employment Commissioners have revealed a depth of moral and social ignorance, of degrading barbarism, in the midst of the very pinnacles of civilization and of wealth, which it were guilt even to contemplate being disseminated amongst our population. No, if it were necessary, in develop- ing our industrial resources, to become as parts of England are, I would not desire the change. But the condition of the working classes in England does not belong to the fact of their being industrious. Isolated districts in that country, numerous localities in America, and on the Continent, shew the perfect feasibility of the union of the most steady industry with edu- cation, with morality, and with cleanliness. K a large pro- portion of the working classes in England are ignorant, are immoral, are drunken, and are unhealthy, it is because no effi- cient system of moral and intellectual education has ever been in operation with them ; that their habitations are crowded into filthy and unwholesome lanes, and that, when released from the toils of their working rooms, they rush to the ale-house to seek a destructive stimulus to their exhausted frames. Is it wonderful that such a condition of society should produce un- 42fi INDUSTRIAL RESOURCES wholesome fruit ? Individual associations in England have endeavoured to remedy this deplorable condition. Their active benevolence and their wealth have founded schools for tem- poral and spiritual instruction, have opened mechanics' insti- tutes and reading-rooms, and thus have given to thousands the opportunities of elevating themselves from the darkness in which their fellows are still immersed. But these local and individual efforts cannot remedy the system. The causes which have led to the bad results of the manu- factm'ing system in the sister kingdom, do not exist with us. Ireland can never become a great manufacturing country, such as England is. Her physical constitution does not supply ma- terials. The proportion of the people employed in factories can, therefore, never be so great. Her sources of power, whe- ther it be coal or turf, or water, lie distributed so uniformly through the land, that the concentration of manufactures, on a few localities, as in England, cannot occur. Hence the evils of vast, unhealthy, manufacturing cities need not be feared. Above all, with temperate habits, and with the education which the National system will give to every individual of the grow- ing race, there is no danger but that industry may be accom- panied by intelligence, intelligence by morality, and all by the steadiness of purpose, and tranquillity of habits, on which the happiness of the family and the peace of the community de- pend. This is the result Avhichit should be the object of all to gain. This would render us independent of the wretched po- litical differences on which we waste our strength. Vast in its consequences, it is yet simple in its means of at- tainment. It only requires that each man intending to live by the land, should learn what the land is, and what can be done with it. That, having so learned, he should apply himself stead- fastly to the practical working of his occupation. So he is cer- tain of success. Success will render him independent; inde- pendence will render him respected, and respect will bring him power. Thus knowledge is power. Practical knowledge ; for power is essentially practical. Such are the circumstances influencing industry in Ireland, which, falling within the range of subjects connected with my OF IRELAND. 427 professional duties, I have thought it not unimportant, at the present time, to offer for public consideration. I have not en- tered into every source of employment which this comitry could afford. T hus I h ave touched but lightly on the details of Jte I cultivation of waste l andS] and not at all alluded to the subject, so important in itself, of fisheries. These topics I did not in- \ troduce, because their importanc e and their practicability are I ^'"'^ universally recognized . My object was to point out that the constit ution o f the rocks and soil of Ireland, its contents in ores a nd f uel, its su^plyof water, its extent of lakes and rivers, its harbours, all fitted it for industry in agriculture, in manufao- ' tures, and in commerce, in a degree, which, although not en- titling it, like England, to grasp at the commercial and manu- ; facturing sceptre of the woi'ld, would certainly enable it to be \ the source of employment and comfort to its own people. For \ the attainment of this end, it was necessary to remove some errors regarding the true foundations of industrial success, to describe, with a certain detail, how far the materials for in- dustry exist naturally in Ireland, and to point out, how in- dispensable to the employment of even the richest gifts of na- ture is practical education in industrial knowledge. If even a few are induced, by the facts and arguments I have brought forward, to reflect upon these topics, to discuss them, and, if satisfied, to act steadily upon them, I shall consider my object as being: grained.
