ADVERTISEMENT To arrive at a reasonable accuracy in describing a new and partially explored country, the explorations of which have been by very many different individuals, a mode of giving the description must be adopted corresponding to that by which a conflict between two armies is described. No one person having been able to see all the different points to be described, the statements of various persons must be taken, in order to a knowledge of the whole. In preparing this work, therefore, I have had recourse to eveiy available source of information, scrutinizing and comparing the dif- ferent statements. And to the end of my principal object, that of presenting, in a condensed form, the disseminated facts which great national interests require the public to be in possession of, I make no apology, but would give full credit for the copious drafts and conden- sations from the Reports of Officers of State and general governments, as well as the personal communications of many intelligent gentle- men, for whose contributions I am under many obligations. Facts and information which I have been enabled to obtain only by perseverance, toil, and personal observation, are joined therewith, to- gether with deductions sifted from concurring accounts by old voya- geursy half-breeds and Indians, delivered in their barren compound, from the Indian, French and English languages. It is with feelings of regret and justice to the ever-to-be-lamented dead, I say, that for the Geological and Mineralogical information herein presented in a condensed form, I am indebted to Dr. Hough- ton's Official Reports, and perhaps, in a strict construction of those terms, am, in other parts, more a compiler than tk*r THE AUTHOR.

CHAPTER I. Having visited tlie mining region the past season ; having neglected no means in my power to ascertain the truth or falsity of the statements, and of my suspicions as to that, by many imagined, " El dorado" of the North ; having taken great pains and labour to arrive at local facts, under the recollection of the " many grains of allowance" with which I had received the best authenticated statements myself; having no interest of name or nature in the effect my state- ments may produce, except that in common with all other citizens, in an early and prompt development of those inter- nal resources of our country which will leave us independent of foreign supplies ; I comply with the wishes of many acquaintances, who desire the information I have obtained, too lengthy in detail for the frequent repetition necessary to gratify personal friends only, by this publication of facts as I found them, without " fear or favour," " nothing extenuat- ing, or aught set down in malice." I am impelled to this publication, too, not more that the truth and real merits of the country may be known, than to rihow, by such deductions as the careful reader will make, that '* all is not gold that glitters." The realities are suffi- cient ('* and to this end must we come at last,") to insure all that should be desirable to accomplish, except the ulterior objects of those w^iose " baseless fabrics of the brain" must fall, and visionary schemes, in the end, '* come home to roost." 1* ( 4 ) Upon the capitalist is the dependence for the necessary means of developing our mineral resources, and upon correct information only can he be expected to furnish it. Over- wrought and gilded statements, through whose glossing the careful and discreet man sees their hollowness, may deceive many, and accomplish the ends of some, but will also retard or prevent great results, v/hich candour and truth might have produced, but for the doubts which discovered duplicity throw in the way of investigation. Congregated capital has been necessary in all countries and times for the development of mineral resources. Nature, in her organization of matter, decreed it " when the waters covered the face of the earth;" and, as much as she has favoured this region over all otliers with her mineral wealth, there is also, as elsewhere, written upon it, " Thou shalt eat thy bread by the sweat of thy brow." Abundant and pure as are our lead and iron, our copper is not less so ; and if there is one fact which characterizes the bounty of nature to ours over the mineral of all other countries, it is that/«c^ and peculiarity of our Lake Superior native copper, that it is in no instance contaminated ivith alloys of other metals. The assertion of which fact, when made by Dr. Houghton, was treated as a burlesque by scientific men at home and abroad, who called it " backwoods mineralogy." His representations as to the great abundance of copper indicated by " surface appearances," were treated as " new country stories," and Dr. Houghton, smarting under this ridicule, pursued his researches for ten successive years be- fore his reports elicited any public attention. He has gone down to his grave in those depths, though immeasurable, and upon a rock, though unseen, which he knew and could determine in his system of philosophy, as well as if " the waters rolled back" when he came to their margin. He has gone, too, in the day when that future he had so long and confidently anticipated — was come, which, by its develop- ments, was about to consummate the silent but prevailing ambition of fifteen years of toil, leaving one point only fully established — that the accepted systems of geology and miner- alogy are in many particukirs inapplicable to the scene of his labours — of which the above is one proof. True it is, and lamentable too, that wild and exaggerated, ( 5 ) not to say entirely false statements have been made of min- eral wealth there, to be heaped together without labour or means, which could not fail suddenly to enrich the fortunate holder of a few shares of some particular stock. Between the extremes the capitaUst must designate, or nothing can be done in bringing out the wealth of such mines as do exist and have a value. Many have already embarked, but nothing like a number adequate to the field presented. Extreme caution is not a fault, but often loses what investigation and promptness would have garnered. The first workers of our iron almost invariably failed for the want of means, and from an influence felt by them from afar, but never seen — neither of which exist in reality now. A few years will, as in lead and iron they have, show our capacity to supply the world with copper, not less imagined at present, than it was that we would now do it with lead, when the law of 1803 was passed, with a view to ascertain if we could not produce a portion, however small, of our own consumption. Look now at the mighty result. We send it to China, and above it is piled our cotton cloths and wooden clocks, and who can say that copper will not follow ? Lead is worked, and many fortunes have been made in its production. Copper must be worked in the same man- ner. The mining is the same — the smelting differs—but copper ore is worth vastly more than lead, while the cost of mining is about the same. This reduces the whole subject to one or two questions, viz. : Ts there copper ore as stated ? and, where are its locations'? These questions the reader will find answered in the following pages ; and if he will read them carefully, and qualify himself, as he may, by their contents, he will be able to determine correctly between pro- positions now or hereafter made for investment, which are real, or which are " kiting." If he is too much engaged to do this, but goes in, hap-hazard, he may hand down at his death some " shares" which had long before formed fellow- ship with North Carolina '* gold stock." I am not about to advance objections to, or recommenda- tions of, any companies, other than may exist in a list of companies working, and which is not intended to be invidi- ous, if it shall be so construed. I give the list with the object of showing what has really been done in the country ; and ( 6 ) there are other companies, who have equally favourable positions, prospects and leases, who will another season pro- ceed vigorously in their contemplated operations. That there are differences between the companies is mat- ter of course ; and those diffeiences consist in some leases being for three miles square, and subsequent ones for one mile square. Some companies arc located upon good har- bours, enjoying facilities which others do not. Some com- panies have several of these three mile leases : some com- panies have several one mile leases. A company may have only a single permit for one mile square, which may again in some part, not forty rods square, have more value than another company's possessions covering miles of land and the best harbours. By this it will be seen how necessary it is to be well informed as to localities, geology and mineralogy, as well as facilities, which are so materially to affect the value of points proposed for the investment of capital. That the reader may commence his voyage understand- ingly, before we start to coast round the shore, I have pre- sented for his careful perusal with the maps, a broad view of the whole country, defining the location of the various strata of rocks, of which the mountains and valleys are com- posed, and where those are met with. I have given the different kinds of rock, and where they occur, together with the mineralogical contents of those rocks, immediately following ; so that wherever any of those rocks are found, he may look for their described contents. If those are not there, non» other will be ; vice versa, wlierever described minerals are found, there look for the rocks to which they belong. A close study of the few pages here presented upon this matter of '• formation, place, and contents of the different rocks," will enable you to see clearly your way through the country, and also the contents of the hills and mountains, and bottoms of the lakes. A small fragment, picked from the beach at White Fish Point, may have been years upon the journey from the place of its detachment, and that place may be hundreds of miles from you, which you have never been nearer to than at present ; still, you will be able to put your finger upon the spots of the nativity of its kind. So will it in a very short time be with regard to specimens ( 7 ) of copper. A careful perusal of the contents of the different rocks, and a familiarity with specimens which I have depo- sited at the American Institute, will enable you to tell at a glance what rock, region, and often the vein, a specimen has come from ; and what has come to be called " grafting,'' or taking specimens from one location, and pretending that they came from another, where the rock is different, you will soon detect. I have also given a list of native metals, their appearance, colour, consistency, gravity and situation found in. I present a hst of terms used by miners, v/ith their signi- fication, accompanied with certain geological and mineralo- gical terms which occur in the pages. I also show the entire coast, the rivers, harbours, islands, Fon du Lac and St. Louis rivers. ^ To the traveller for pleasure, let me say a few words. When you shall have read the round upon which I have taken the coaster, you will probably shrink from the toils of following the shore, and wish to go direct and quick from place to place, or tarry a time at one place and then go to another — in either case, there will be every provision next season. A steamboat, large, staunch, commodious and safe : a propeller with all these qualities also, and a number of very convenient schooners, as will be seen by the hst of vessels on Lake Superior. If you are in pursuit of pleasure, whether lady or gentleman, you can find it in the Lake Superior region, provided you can be pleased witli grand scenery, water-falls, lakes and mountains. You can ramble in search of Agates and Cornelians, in which, of all I have seen engaged, I have never known one tire of the amuse- ment yet ; to become so fatigued as to stretch upon the peb- bled shore and search within the reach, then crawl a space and there search on, and still as anxious and intent as when first beginning, till time, who is flying while you are absorbed and unconscious of his flight, l)egins to dim your vision with a dechning sun, and weaken discrimination of the prize you seek ; — then rousing to consciousness, you see the sun that hung high in the heavens when you comjnenced your search, just sinking in the waves, and reflecting, you seem to have been away in another world and just Returned ; you look about for some known object almost doubting your identity ; ( s ) reluctantly you shape your course for home, but hope Hnger ing hangs upon the way ; though fatigued and O'erloaded with the selections fancy found, You'll pick, look — ' one more,' you'll say — " Another with those 't are to be ground," Or examined dry, be thrown away. This is Agate hunting, as all will testify who have tried it, the most fascinating and bewildering yet certainly innocent amusement. I have seen a staid and dignified old Governor stretched at length upon the shore from very exhaustion, absorbed and lost to every thing but examining agates, con- suming half an hour in scrutinizing and admiring the varie- gated tints, the beautiful blending of shades and colours, and die regularity of the myriads of diverging and concentrating Mies of different colours in an agate he gazed upon, not larger in circumference than a dime ; or tired of this you can wander away with " hook and line," to the bright and beau- tiful lakes that lie among the hills ; or take your gun, for The Pigeon and the Partridge's there, The wild Duck and the timid Hare — hut no snakes! I have never heard of any in the country. Or take a bark canoe, which two or three trials will make you at home in, for they are much easier to get the " hang " of, than most persons suppose ; go to the adjacent islands, run into the caverns and grottos which cannot be reached in any other way. You may find rare agates there after a gale, and when you return, keep along tlie shore and examine the bottom marked by the white spar veins discernible at thirty or forty feet deep, or nearer shore with a forked stick bring up the stones you fancy agates beyond the reach of those on shore, and when you get back you will have an appetite ; the tonic air of that region, and the v/ater, will make a new being of you in a few weeks. The air is bracing yet soft, and is pleasant in " dog days," witliout producing that faintness and lassitude of the warm weather you have been used to : and the water — well, you will not be singular, you will then say you have never drank any water before ; and when you return whence you came, and again drink of that you once thought delicious, you will condemn it as an adulteration, or spurious. ( 9 ) To the invalid, I have a few words to say, for his infor- mation ; I am not " cracking up the country," for I shall write nothing that all who go, will not find as I represent it, or all who have been will not confirm, either on this or any other subject of their acquaintance which I treat upon. To you I say, go thei ; although your health is impaired you cannot be injured,' and I know one gentleman who had been south ; had been to Havannah without any benefit ; one season on Lake Superior restored him, as he said, to com- parative health ; he was a companion ' du voyage.' I don't know why it should not relieve consumptives as well as others, all who go there declare they feel much better — and I know I did. I was under a slight chronic and cutaneous alfliction ; I was told that the lake Fanny Hoe, on which Fort Wilkins stands, was so much impregnated with mineral, that a soldier died from drinking of it. I asked if the other soldiers had not drank it as well as he, and was informed they had, but its water had since been analyzed and found to contain too much copper. Upon this I resolved to drink the water of Fanny Hoe lake, brackish as it might be, and continued to do so while there, and I firmly believe it to be beneficial in cutaneous affections. 1 didn't die, as the soldier did, but felt better every day I remained. One thing is certain — the half breeds and natives all live to a great Jige, notwithstanding tlieir exposures: and sickness from fevers, colds, inflammations and agues, is scarcely known ; the healthy and ruddy appearance of all you meet will be a stronger guarantee and more satisfactory evidence, on your arrival, than any philosophical reasons I am able to give. I am assured there will be prepared early next spring, accommodations for travellers and sojourners, at all the places desirable to stop at. Even now, every hospitality is afforded which can be, but especial preparations will be made early, for next season's " passengers and baggage to and from the steamboats." The maps herewith presented, are the most correct possi- ble to be oftered at this time. The chart of Lake Superior is perfect. It may not be generally known, that Lake Huron and Lake Superior have been as perfectly surveyed as science and time can do it, and this chart is a result. Lieut. Bayfield was several years engaged by direction of the British govern- ( 10 ) ment upon this work. The chart herewith, is a copy reduced by the " London Society for the diffusion of useful knowledge," from the map reported by Bayfield as a result of his labours. Its accuracy is attested by all of any acquaintance with that Lake and shores. The map of the Mineral Region and Locations made, was taken from the standard map in the office of the Mineral Agency at Copper Harbour, containing the locations made up to the 1st day of November last. I have added to it many lakes, harbours, rivers and islands. So far as leases are granted, this map is perfect in designating locations, be- cause the survey is made by a United States surveyor before the lease issues, and their locations may be depended upon. The numbers and squares designating Locations, are in the main likely to be correct when in the vicinity of Leases, for in such cases the locators have established cor- ners and lines of those surveyed Leases to work from, in measuring and describing their own. But as I am dealing in facts with the reader, I must say, what experience has al- ready shown, and the future must confirm, that there are difficulties in designating upon a map, without any great right lines fixed to govern it, the precise position of an isola- ted survey. The location may be correct in all particulars as described, the starting and governing points all known, and the measurements correct, while its position upon the map would be erroneous from the want of a base and right line whose measurements would fix it accurately. Another, and which may hereafter be a prolific source of difficulty and contention, when positions come to be defined as de- scribed, by correct surveys, is the variation of the magnetic needle in the mineral region ; accompanied too with the known difficulty of measuring distances correctly in the thick bushes, except by the most patient and careful attention to accuracy, obtained slowly and by great labour, and an ad- herence to an undeviating system ; then seldom, or never without the solar compass to determine at every station the '* variation." In this particular, of such paramount importance in making a location, some I know, and many I doubt not, have heen negligent — defining their starting points, courses and distances by a pocket compass, and pacing their mea- ( " ) surements. All can judge of the probable results in such cases from a statement given me by Mr. Hill, one of Dr. Houghton's head surveyors, that there were places in the mineral region, where the compass would, following a given course by it, lead on a semi-circle in running one mile. Now suppose an individual, in locating a permit with an ordinary surveyor's compass, has started his course east at one of these places, and has run a semi-circle ; he does not know that he has so ran, and consequently says in his de- scription, " from thence, east one mile to a blazed Spruce tree, which is the north-east corner." He does not know but it is so, and goes and marks his position and gets his permit certified with this description. When this location is run out by his given courses and distances, with a corrected com- pass, his "blazed tree" is found to be about three-fourths of a mile from where he supposed it was ; and the mineral he intended to locate upon, is off of his location. To what ex- tent this is the case I have no means or disposition for esti- mating. Again, there have been persons lingering about the office at Copper Harbour, with pockets full of Permits for persons never in the country, and never intending to be there, who came to be known by the name of " Pa^^77^ec5," from their putting their paws upon the shoulder, and "a word in your ear " to every explorer who had really made examina- tions, the moment he arrived. One would not be done with his *' one side " inquiries, before another ^^zm;, and, "a word in private " — each hoping to get an unguarded word on which to locate some of his "friends' permits." I was told, with what truth I know not, though my authority was an * old 'un,' that some of the Pawnees have been "awfully stuck," to use his expressions; " for," said he, "some of their per- mits are located where they can't touch land up, nor down^ nor sideways — and others ainH nowhere.'''' This might have been true in some particulars, but usually the " Pawnees," where a location was marked on the map by an explorer, located around that, and bounded from its description in making out their own, which I have no doubt in many cases will cover the spot the explorer intended. An anecdote is related of two of these Pawnees in whom the habits of" pri- vacy" was extreme, meeting when each had communications for the other. They met in an open space, twenty rods from ( 12 ) any person, and after whispering in each other's ears as if announcing their mutual desire to be "private," locked arms and walked to a more remote position. CHAPTER II. A VIEW OP THE SHORES, RIVERS, BAYS, HARBOURS, AND ISLANDS OF LAKE SUPERIOR. All explorers, with scarcely an exception, when they set out for the first time, encumber themselves with about as much that is useless as that is useful. I will therefore state what is necessary only, as the necessaries are usually found quite burdensome enough. If you intend to " coast round," you must provide at the Sault St. Mary a bark canoe sufficient for your number, and provisions for the estimated time, which must allow for de- tentions, &c., until you reach Grand Island, as there, at Granite Point, (Dead River,) and L'Anse, provisions will probably be obtainable next season. You will require a tent, two blankets for each, a camp kettle, frying pan, tin cups and plates — if you are nice, a coffee-pot, ground coffee, and sugar; but the plates, coffee-pot, &c., may be dispensed with, and often are, the kettle or frying-pan being the dish from which each helps himself,— the knife is in your belt. The sail of your canoe is laid upon the boughs, which are first spread upon the ground in the tent, and then your blankets. At landing, the canoe is not allowed to touch the bottom, but you get out into the water and unload it, which is then lifted out upon the shore, turned bottom upward, and your stores are secured under it ; your tent is pitched, a fire built, &c. This is all, however, the work of the voyageurs, who, from practice, will despatch it with a facility that will quite astonish a new traveller. Your clothing should be a pair of thick-soled boots of cow- hide ; no stockings are required, but most persons wear them, and consequently have the nightly recurring duty of drying them almost dry, and thus putting them on damp in the morning, producing a contest between the boots and feet of ( 13 ) entrance and resistance, rather disagreeable. A pair of pants of cotton canvass, and a coat of the same to reach below the knee, with side and breast pockets. Cotton canvass is found to be as good as anything to turn water, and the best to turn the brush, which is a work of labour and perseverance often to be endured for hours in exploring. A red flannel shirt, will not require so often washing as a cotton one, and " it is always warm and dry, though never so wet and cold ;" be- sides, washer-women are rather scarce, and when you have performed the office yourself a few times, you will become less fastidious in relation to such matters. A red woollen comforter. No suspenders ; they will confine you in crawl- ing under logs and limbs, and through difficult passages in the cedar thickets. A belt, carrying a hatchet and knife, buckled round the waist, will sustain your pants, and allow free exercise of your body and limbs. A wool hat, with wide brim and low, round crown, is the best to turn rain and brush. A pocket compass, and perhaps a pipe, completes your equipment, saving a few fish hooks and line. These are the really necessaries, though most travellers are not con- tent with them. Experience, however, shows the necessity of being divested of everything which may be dispensed with ; for, portages and journeys have to be made, in whicli every thing, even the canoe, must be carried for considerable dis- tances, on which occasions •' blessed be nothing." Habit, however, brings power of endurance which many would not believe, and I have seen a packer, himself weighing less than. 145 lbs., who could take upon his back 200 lbs. weight, and make good time upon the portages. In coasting, it is necessary to have at least one good *' voyagcur^'*'' as they term themselves, who will most prob- ably be a Frenchman or a half breed, who understands the coast and weather-signs, — superintends the unlading and camping — interprets— knows where fish may be taken — the proper places for landing, and whose counsels — as to whatever hnplicates safety or convenience must be followed, and with rare exceptions may be ; for, experience makes them wise in things which gives their knowledge the appearance of intui- tion, when contrasted with their general endowments — as, the coming of a storm, the probabilities of reaching a par- ticular necessary landing-place by a given time, &c., f abrupt and precipitous cliffs upon the immediate shore, as dso a range of well defined hills, a little in the interior, vhich have an elevation of from two hundred to three hun- Ired feet. After appearing, for a few miles upon the coast, his rock gradually stretches into the interior, following the ine before described as the most northerly bound of the outer rap range of hills, and invariably occupying a place to the lorth of this range, and it may be observed, nearly or quite, continuously as far as Montreal river, which stream it crosses It a short distance above its mouth, thus making its length vithin the limits of Michigan, computing its southerly cuiTe, something over one hundred and forty miles ; but the rock loes not cease at Montreal river, for it may be seen at short ntervals in the interior as far westerly as the head of Lake Superior. At the trap knob of Granite Point, the conglomerate is mperfectly developed, but on the south-westerly side of Isle Royale it is much more perfectly so, flanking the hills of trap upon the southerly side. The conglomerate is imper- fectly stratified in masses of immense thickness, and it dips upon the south shore of the lake regularly to the north and north-west (in conformity with the variation of the trap hills in their direction) and usually at angles of thirty to eighty degrees, while upon Isle Royale and the north sliore, the dip is reversed, being south and soutli-eastcrly, or in other words the rock upon all sides dips in the direction of tlie lake basin. Upon the south shore a little east of Montreal river, this 6 ( 62 ) rock was estimated to be 5,260 feet (nearly a mile) thick, and it wedges out or thins so rapidly, that near its eastern pro- longation the estimate was 1000 feet. Its greatest estimated thickness upon the north coast was 2,300 feet. The trap dykes of this rock, are usually parallel to the line of stratification and dip, and are from fifty to several hundred feet thick, sometimes continuing several miles. In addition there are veins of a more recent date traversing the conglomerate and the dykes always at high angles with the line of the conglomerate. These last veins, which are usually more perfectly developed near the junction of the conglomer- ate and trap, or for a few thousand feet on each side of that junction, are clearly seen true veins and are with few unim- portant exceptions the only veins of this range which are metaliferous. For minerals of the conglomerate rock — see " Minerals of Conglomerate and Red Sand Stoned CHAPTER VI. Mixed Cotiglomerate and Sand Rock. — This rock is made up of an alternating series of conglomerate and red sand stones which rest conformably upon the conglomerate rock last described, dipping with that rock into the bed of Lake Superior. This mixed rock was not noticed upon the north side of the lake, or upon Isle Royale, but upon the south shore the rock was traced continuously for a distance of about one hundred and thirty miles, extending from a few miles westerly from the extremity of Keweenaw point, to Mon- treal river. It follows the line of the conglomerate before described, stretching from Keweenaw point in a south-wes- terly direction, and again curving to the north-west, forming as it were, a crescent, the result of which is, the rock only appears for a limited distance upon the lake shore at Ke- weenaw point. From a point eighteen miles easterly of Montreal river it wedges out or thins rapidly ; proceeding west, and towards the head of the lake it wholly disappears or becomes merged in ( «a ) le conglomerate below and sand rock above. Its greatest bserved thickness was four thousand two hundred feet. The conglomerate portion of the mixed rock consists of ;rata of conglomerate varying from a few feet to several undred feet in thickness and composed of materials in all aspects resembling the constituents of the conglomerate )ck already described, and similarly situated. Tlie sand stone portion of the formation occurs in a strata f very nearly corresponding thickness, and the two rocks lay be said to form nearly equal portions of the mass. But le material of which this sand stone is composed difters idely from that of the true sand rock lying above, for while re latter is chiefly made up of the quartz ore materials, the >rmer is composed of materials bearing a close analogy in imposition to those of the conglomerate rock itself; or in ;her words, the sand stone consists cliiefly of green stone so luch comminuted as, when cemented, 'to compose a coarse md stone. It will thus be seen that the members of this irmation differ only in the degrees and fineness of the ma- rial, and the character of this material will explain suffi- ently why the true conglomerate and the mixed rocks are iferable to the same origin, for the materials of the several lembers of the group have their origin from the trap rock, fid as a whole, may perhaps be regarded as a trap-tuff. The coarser conglomerate of the formation is scarcely jparated by lines of stratification, and the strata appears 3ually in mass, embraced between the strata of sand stone, it the stratification of the latter rock is perfect, and it bears adence of having been deposited in shoal water, in the very :>undant, perfectly defined ripple marks which it exhibits trough its complete range. No fossils were noticed in con- action with either the mixed rock or conglomerate lying 3I0W it. Dykes of green stone occasionally appear in the mixed »ck, but less frequently than in the rock below. These ^kes almost invariably occupy places between the strata of le rock, and correspond in position to the direction and dip * the rocks by which they are embraced, or in other words, le rocky matter composing the dykes appears to have been ijected in a plane corresponding with that of the stratifica- Dn of the embracing rock. As in the conglomerate below. ( 64 ) these dykes have produced very great changes in the colour and structure of the mixed rocks bounding them on either side. In addition to these, the mixed rock is occasionally (though less frequently than the rock below) traversed by veins or cross courses of a more recent origin than the dykes (which latter tliey usually cross at a high angle,) their course being usually at an angle of sixty degrees opposed to the line of bearing of the mixed rock. These cross veins are usually made up- of a calcareous spar or a sub-granulai' lime-stone, and more rarely of some variety of quartz and imperfect trap rock, the latter usually of the amygdaloid variety. For minerals of the mixed conglomerate and sand rock, see Minerals of the Conglomerate^ Mixed and Red Sand Stone, CHAPTER VII. Red Sand Stone and Shales. — This rock and its accom- panying red and gray shales occupies a much larger extent of country bordering upon Lake Superior, than any other single rock or group of rocks. It rests upon the primary and me- tamorphic rocks, immediately west from Chocolate River ; upon the conglomerate and mixed rocks, from near Eagle River, of Keweenaw Point, west to the head of Lake Supe- l^or ; upon the primary trap, metamorphic and conglomer- ate rocks of the north shore of the lake, and upon the con- glomerate rock of Isle Royale. It is this rock which forms the basis of the level plateaus, or valleys, occupying the spaces between the several ranges of hills south from Lake Superior, and west fi-om Chocolate River. In these last situ- ations this rock is frequently seen undisturbed to surround the basis of isolated knobs of granite, though w^hen near to, or in contact with knobs of trap, there are invariably evi- dences of very great disturbance. The rocks of this group are thickest at their westerly prolongation, thinning out as they proceed easterly. With the exception of that portion of the coast from Point Iroquois to Grand Island, the predominating rock upon the immediate coast, both on the south and north shore, there is ( G5 ) \ sand stone, for even the primary trap and conglomerate 3 almost invariably skirted with it. It is over this rock It the waters are discharged at the Sault St. Mary. On th the north and south shores this rock invariably dips into ; lake. This is the chief rock that appears upon the immediate ast of the south shore of Lake Superior, and it may be d, almost the complete coast of the lake. In coasting tsterly, from Grand Island to the head of the lake, one >uld imagine he had seen little else than red sand stone, d in fact, were he to confine his examinations to the shore >ne, would see no other rock for nineteen-twentieths of the itance. It is the only rock seen, in place, from Grand and to Chocolate River ; and from Chocolate River to 3weenaw Point, embracing the complete width, of the pri- iry, metamorpiiic, and trap ranges — the hills forming 3se groups are ahuost invariably surrounded or flanked their bases with this sand rock, so that even along this rtion, the hills are cut off from the lake by a narrow belt it ; and northerly from Keweenaw Point to the head of I lake, no other rocks appear upon the coast, except a few ip dykes in the vicinity of the Porcupine Mountains, and Iron and Black rivers, and a more recent deposit of clay d sand west of Keweenaw Point. It is also the southerly le of Isle Royale. The materials of which this rock is composed differ widely tm that of the sedimentary rocks described ; for while they e made up of materials clearly of trappean origin, in which very rarely quartz, this under consideration is composed materials, the predominating portions of which are clearly rived from the granitic and metamorphic rocks, in which artz is abundant, though with this there is usually associ- 3d more or less sand, that has all the characteristics of the mminuted trap, constituting that portion of the mixed ck before referred to. Magnetic iron sand sometimes he- mes a constituent of the red sand rock, and occasional ntinuous strata of several inches thickness, are almost tiolly composed of this material. The components of this ck are usually cemented by calcareous matter, highly col- ired by the peroxyde of iron, frequently associated with giilaceous matter. 6* ( 66 ) While the chief mass of the rock is a coarse grained and somewhat compact sand rock, there are portions of the for- mation where there are well-formed red and gray flags, and red and green shales, forming as it were beds of a very con- siderable thickness, and occupying large districts of country. These red and green shales are more largely developed in that district extending from Granite Point westerly to Ke- weenaw Bay, and upon the south shore of Keweenaw Point, extending from the head of the bay to near the extremity of the point, and largely developed. These shales more usually occur in alternating bands of deep red and green colours, the red greatly predominating, and thus are made up of ar- gillaceous matter of sand, the whole material being of ex- treme fineness. On the south side of Keweenaw Bay, near its head, an argillaceous rock appears and extends for a short distance along the coast, which is an anomaly. The rock is evident- ly embraced in, or rather may be said to constitute a mem- ber of the sand stone series, but it differs widely from any other rock seen in connection with it. It sometimes appears in the form of a slate, though usually a compact strata, fre- quently of several inches in thickness, closely resembling indurated clay. Innumerable strata or thin layers compose the mass, being of different colours, red, gray, dark brown, alternating in the same hard specimen. Its material possesses an extreme degree of fineness, and is so soft as readily to be cut with the knife, rendering it a material from which the Indians have long manufactured pipes. It is too soft for use in sharpening tools. The rocks belonging to the red sand stone formation, bear the evidence of having been deposited almost universally in shoal water, for the ripple marks occur abundantly at all points where the rock takes on the decided character of sand rock, and these ripple marks may frequently be seen for many miles together, as clearly and distinctly defined as they are in many of the shoal bays. Fossils are rare in these red sand rocks. This rock is less frequently traversed by dykes of trap than either of the rocks described, though dykes sometimes trav- erse the whole of the several rock formations up to and in- cluding the red sand stone. Upon portions of the north ( 67 ) (Bst, where conglomerate and mixed rocks are more fre- lehtly wanting, and where the red sand stone is brought ore nearly in contact with the trap, these dykes are of more ^quent occurrence. It is deserving of remark, where the iver rocks are either in part or wholly wanting, the red nd stone usually becomes of a deep brown colour, and the aterial of which the sand is composed, gradually changes )m that before described to green stone. The Sand Rock. — It has been estimated that at its west- [y prolongation, the sand rock attains a thickness of 6,500 St, gradually diminishing to the St. Mary, where it com- ratively runs out. The red also thins out proceeding utherly or inland from the coast, at a more rapid rate than 3 fifteen feet to a mile allowed the sand rock, as was most tisfactorily shown when connected with the several pri- iry, metamorphic and trap ranges of hills, for all, or near- all the valleys after passing the outer northerly range of ip hills are based upon this sand rock, and since we have ery reason to believe that this sand rock was deposited in rt during the gradual elevation of the several chains of lis,- it would follow that over these districts which were ist elevated the rock would attain its greatest thickness. The red sand rock south of Lake Superior, as well as »on the immediate coast, dips regularly northward, while at upon the north coast dips invariably southerly, or, as s been already said of the lower rocks, this rock dipsreg- arly upon all sides into the basin of the lake, being in- cased however in quantity as it approaches the primary and stamorphic ranges. The line of cleavage of some of the embers of the lower sand rock and shales is frequently ■egular, and opposed to the true stratification of the rock.

It is a gray or brownish sand rod almost wholly composed of quartz grains usually feebl cemented with calcareous matter, in which it differs from tb red sand rock, as well as in epoch of disposition, and shou] not be confounded with it. Besides, while the red san rock dips regularly northerly, this gray sand rock dips £ regularly southerly, conforming to the hmestone resting upo it, while itself resting upon the uplifted southern edge of tli red sand rock below. From Point Iroquois it stretches westerly, in an elevate and regular chain of hills, to Taquaimenon Bay, wester] from which the shape of the coast is such that these hills c not again appear upon it, until we reach that precipitoi portion of the lake coast known as the Pictured Rock where the effects of waves and frosts upon its feebly cemen ed materials have left portions in overhanging precipices, b the destruction and removal of weaker and less resisting po tions, creating caverns and domes, both grand and fantasti From the Pictured Rocks the hills composed of this stor stretch off to the south-west, passing entirely south of the pr mary trap and metamorphic regions to a distance unknowi This, like the lower sand rock, abounds in ripple mark and its line of cleavage regular and frequently opposite tl line of stratification, passing over considerable districts ( country. Two indistinct species of fucaides were the on. fossils found. The estimated thickness at the Picture Rocks was 700 feet, thinning out, like the others, towar( the east. Tertiary Clays and Sands. — Stratified clays and sar are seen at many points, and continue for long distanc* upon the coast of Lake Superior, and they are largely deve oped at many points in the interior of the country, whic sometimes attain a thickness of 200 or 300 feet, and aj spread over the less elevated portions of the district, beinj in many instances, the covering of the rock forming the va leys and plateaus, and sometimes forming the lake shore. ( 69 ) CHAPTER VIII. MINERAL VEINS. "It will be necessary to keep the relation which the rocks and veins traversing them, have to each other, constantly in view.} Veins are intersected with other veins, and sometimes with reins of other metals at both acute and right angles. Two ines approaching each other, generally have a large deposit it their confluence. It is a good sign if the branches or odes enlarge in width or depth, but bad if they are liorizon- :al or rising. It is a sign of a poor vein if it separates or di- vides into strings and sharp extremities. It is even a worse sign when a vein descends perpendicular, than when it runs lorizontal. Copper will pay for working when only six nches wide, and Tin when only three inches wide, in the Cornwall mines. The richest depth for Copper Ore, in nines which have been worked, has been found to be from 10 to 80 fathoms (from 20 to 60 for Tin,) although great juantities may be raised at 80 to 100 fathoms, yet the quali- y decreases and the Ore is too apt to be decayed. The reins of the Cornish mines run East and West varying some L5 degrees. The veins of Lake Superior run N. E. and S. W. with slight variations. True Veijis. — The northwesterly range of hills, commenc- ng at the extremity of Keweenaw point and stretching in a 5. W. direction into the interior, are more clearly of .the rappose origin than either of the other ranges, and the rock )f the southerly portion of this range is greenstone, while :hat of the northerly flank is almost invariably either an amygdaloid or a rock approaching to toad stone. So far as the hills lying south of this northerly range are concerned, they would appear to be as a whole, deficient in minerals and the rocks are not apparently intersected by k^einr: or dykes of any more recent date than that of the up- lift of I le northerly trap hills, near the Lake. Veins of a date posterior to the uplift of the trap rock last mentioned, are of frequent occurrence, and traverse a portion af the trap range, pass into the conglomerate and sometimes completely across the three seciimentary rocks, immediately above the trap, for an unbroken length of several miles, rare- ly varying more than 12 or 15 degrees from a right angle to ( 70 ) the course of the sedimentary rocks, cutting across the dyke and conforming to the dip of the sedimentary rocks. These veins all belong to a single epoch and must be regarded as Ti-ue Veins, and all carry the same mineral contents ; and, from examinations it is confidently believed that most if not all the metalliferous veins of the upper peninsular or Lake Superior region belong to the epoch of those under consid- eration. It is true, native metals (particularly copper,) are found in places in the greenstone, but the quantity is small and almost ahvays may be traced to a connection with met- alliferous veins in the vicinity. Native Copper in very thin plates was occasionally no- ticed as occupying the joints of the greenstone of Isle Roy- ale, though in small quantities, but the veins so far as exam- ined there, are less perfectly developed in their passage across the conglomerate, and very rarely contain any traces of Zinc. In speaking of the greenstone. Dr. Houghton says, " I not only include the true greenstone, but also those altered forms of gneiss and gneissoid granite which are sometimes associ- ated with it, while the outer or northerly portion of the same range is usually composed of an amygdaloid form of trap." CHAPTER IX. I R R E G U L A R F ALSE VEINS. "* After perusing the following chapter, the reader will have perceived that the condensations from Dr. Houghton's re- port ceased with the last, which treated of Regular Veins. I wTite this chapter in the hope of inducing more thorough examination and minute investigation into In-cgular Veins. The great bane and loss in mining operations is the vast amounts expended and thrown away upon irregular^ or false veins, which proceeds from lack of power or knowledge to decide between true and false ones. This the reader may call a " conglomerate" chapter, if he will. If the suggestions it contains shall induce inve|tigation of the subject, their ob- ject will be fulfilled, whatever may be thought of their phi- losophy or orthodoxy — against any arraignment for either, ( 71 ) I here enter my caveat, that one possibility is just as good as another, in defining the probable resuhs of an indemon- strable proposition. Where veins intersect the lake's shores, they are almost invariably marked by the appearance of the white spar cov- ering, which, in many instances, are several feet wide, and may be traced by the eye into the water thirty to forty feet in depth. Several of these wider ones occur between Cop- per and Eagle Harbours, in which, when the spar has been removed, boulders and ragged deposites of native copper have been found of various sizes. And from one on the conglomerate edge of the shore, on Lease 15, belonging to the Boston Company, I saw already taken out, two pieces of native copper, one weighing 800 lbs., the other some 60 lbs., which were cut off with chisels and sledge ham- mers from an embedded sheet, four inches thick at the place of detachment, leaving the imagination to fix its own esti- mate of the quantity or extent of that portion remaining in the vein. Scientific men have heretofore contended that native copper existed only, disseminated and as boulders — here, at least, it appears in a sheet, but to what extent, can oi)ly be determined by working. In some of these veins, as at Agate Harbour, different kinds of ore, or, I think, different stages of advance from ore to native copper, are found — such as the mother of ores, glaus, green carbonate, and black sulphuret, all taken from the same vein. This vein and the one from which the na- tive copper spoken of above was taken, are but one mile apart. Native silver and native copper are often taken out attach- ed to each other. Some of the veins, by the reports of analyzers, have a preponderance of silver over the copper from the same vein or rock. See Dr. Jackson's report of the Eagle River vein. Irregular veins are of very frequent occurrence as well upon the surface as below it, which often present the best appearances, and afford specimens very likely to deceive the novice in exploring and mining. There may be injections into a crevice only, which extend but a short way in depth or length ; and though well filled while the cone rai?ed by the interior pressui'e continued, and during which, all the ( 73 ) crevices were wide below in proportion to their depth, and would, had this great cone held its apex attitude, been well filled veins, no doubt leading to large deposites like true veins ; but by the subsequent action they are not ; for that cone's fallen and depressed apex is now the synclinal axis of Lake Superior, to which the strata around it dip. When the gas by which it had been swelled forth found vent and escaped, it carried forth in the explosion those boulders of primitive rock and native metal found in all directions, and then, fol- lowing, forth rushed the conglomerate, and found its level ai-ound the trap hills, which, with fire above and fire beneath, were softened — then it was amygdaloid, greenstone and trap were blended, and then was the native copper disseminated — more in some places than in others, according to the heat and supply of the ore. The apex or cone raised by distend- ing the earth, unsupported at the escapement of the cause, gradually settled back, sinking lower and lower as the inte- rior heat and pressure abated, and the matter in cooling con- tracted, closing first upon the surface, and shutting, as they descend, the seams and crevices opened by the expansion. The closing of those seams, veins, or crevices, in this way, compressed and forced down their contents as far as they closed. Failing, however, to resume their places, in many instances, have left to unknown depths true veins, defined by the wall rocks, which, though showing they have been rent asunder, are also smoothed by the action of heat. In some instances, there is but one defined wall rock, while the other side is filled with native copper, disseminated through- out, as at the deep shaft of the Eagle River. In other cases, as in the Pittsburgh Company's drift, three miles back of Eagle River, both sides are workable, and the metal is dis- seminated in the general rock, showing that the rock had been so heated as to either take up the copper when coming in contact, or to smelt such portions of the ore as it might have possessed in its organization, the latter of which is rather sustained by the frequent occurrence of toadstone, showing that something has passed away as a gas. By this it will be readily seen why miners follow a vein that widens as it descends, even though no ore be immediately found, and discard a vein that contracts, or runs up, or even hori- ( rs ) zontal. Their experience has taught them the results to expect. I have no doubt that we have samples of the inner coat- ing of the earth which is next and in contact with the inte- rior fire or latent heat, presented in the lava^ thrown forth, but changed in quality and appearance by the great heat they are subjected to in their passage ; a heat much more intense than that of the heated matter of the interior, which certainlij is not a fiame, but probably a dull latent fire ^ draw- ing sufficient of oxygen from the earth to keep it like coals imbedded in a grate, and which glow on the admission of the ail". This may reasonably be supposed to be the state of the interior fire until an active property is added. There is but one active property which can reach this fire that will make it the active cause sufficient to produce the effects presented in earthquakes and volcanoes, which property must be oxy- gen. There is a certainty that the supply of oxygen must come from accident too, or there would be a periodical suc- cession of these effects, which is not the case, but whose oc- currence irregularly, shows their origin to be dependant upon an accidental supply of something necessary to the effects witnessed. There is but one way this property necessary to combustion can be accidentalli/ furnished, and it is this: — The best estimates make the earth or shell over this latent fire ten miles thick, which in proportion to the size of the globe, (some eight thousand miles in diameter) is quite a vhin rind, and composed too, of particles constantly changing their position, as the globe changes its shape, through which are distributed veins of various sizes carrying water. The particles of matter forming the globe are continually chang- ing their position, from the tendency which their weight •^aves them towards the equater, (hke clay upon the potter's ;jpindle,) the globe thereby enlarging at the equater and flat- tening at the poles, a process, whose results already have enabled the vision to range sixty miles v/ithin the polar cup; and, by the enlargement of the equator and preponderance of weight on the periphery, instituted a third, or oscillating motion north and south, known as the sun's declination. In this gradual and imperceptible movement of the matter com- posing this rind or skin, over the interior fire, it sometimes 7 ( 74 ) will occur that one of these veins of water in it will be open- ed upon this interior world of latent fire, and the active pro- perty necessary to combustion is thereby furnished. This vein does not furnish sufficient to extinguish, it only feeds. A kind of inflammation commences^ and the supply of oxy- gen in the vrater continuing, active heat and fire are pro- duced. The disease increases and follows up the stream it feeds upon enclosing its way in its melting rocks and tak^ ing new supplies from other streams it meets with ; and thus proceeding, opens at length to some fountain, which, pouring down its v/aters too copious to be consumed, are changed to steam. That steam, increasing and expanding, must escape. The column of the entering water is exerci- sing a hydrostatic power strong as the surrounding rocks themselves ; the steam increases and expands till the rocks split to their foundations; — the earth swells forth: — its weight compresses the steam for an instant : — the uplift set- tles back crackint]^ and breaking in all directions. If these throes shall dam up or cut off the supply of water, and after a partial escapement, leave a circumscribed and steady supply, the interior inflammation of the region will have an issue cafled a volcano. The mountains are raised and may remain or partially settle back. But, if the supply continues upon the fire, the gas will generate and expand, the earth still con- tinues to swell forth, opening wide interior, and raising the apex of the cone at every succeeding expansion of the in- creasing power, till, breaking through, the humid steam first shoots up a cloud filled with dust and ashes, followed by in- tensely heated matter, composed of contributions from the different strata it has made its way through to the surflice ; there the oxygen of the atmosphere rushes to it and gives the outpouring mass a blazing glow. Into the vacuum thus formed, the distended cone settles back, — perhaps gradually, — may be quickly, drawing the dip of surrounding strata to an axis. This may be so, or it may not be so. I have never seen such operations — only the effects. Who will suggest a better way of doing a large job of strata piling, mountain and valley, earthquake and volcano making l Should it be that the different ores are distributed pro- miscuously through the interior of the earth, in horizontal layers or strata of various thickness and at different depths, ( ''o ) we may begin to account for native metals, or those found in such purity as to be called so. These ores being soft and earthy in their beds, are carried up by the first escaping col- umn ; some ejected in the explosion as dry dust, other por- tions, smelted in their passage, thrown forth, cooled, form the boulders ; other portions in their liquid state run into cav- ities or cooling in the seams remain, showing, that in their particular cases, the necessary heat and accompaniments for smelting the ore, had somewhere combined. In other in- stances where the combination was less perfect, other states of purity are presented, as the boulders of black oxyde, hav- ing 70 to 80 per cent copper; and the sulpturets and sul- phates all indicating different degrees of perfection in the action which the ore has undergone. The reader who is opposed to theories, may say this di- gression is a *' foolish philosophy," and has nothing to do with mining. But from what I have seen of the mines and veins, I am of opinion it will be found worth thinking upon by all " exp/ore?-s," and ^^ prospectors.^^ Were this the proper place, I would like to carry this theorising a little further, and endeavour to show, as I be- lieve, that this world has undergone, and will again, changes in its nature, constitution^ and power of production, of not only animal but vegetable organizations, involving causes and effects, in whose history our system of geology is the record of the things of yesterday, and that the prophet Daniel's " Overturn ! Overturn ! Overturn !" three times repeated, had a meaning in natural philosophy which the Schools do not teach, or the Savans understand in this day, viz : — that the oscillations of the globe, from the enlarge- ment of the equator, and flattening of the poles, will, in 12,000 years, as the Hindoos say, change its axis, which will undoubtedly be known, as it was to Noah, seven years ahead, by the immense ratio of the yearly increase of the arc described upon the heavens, and marked by the heavenly bodies, as the sun's delineation, when the consummation approaches. Also show, that Daniel's " time, times and a half time," and " restoration of all things," was a part of the same subject, and would require the time of two and a half changes of axis, or the great Egyptian cycle of 30,000 years, which would restore places and limbs of the ( '6 ) earth to their positions of latitude and relation to the planets geocentrically, which they had occupied at the commence- ment of that cycle, when the earth would probably be a perfect globe, and the sun have no declination. Further, that, at each of these changes of the axis of the globe, the earth, or rind often miles thick, is liable to be " burned, and not consumed," by the rushing in of sufficient water and air to extend the combustion, till the rind or earth breaks in by continents, and the v/hole be changed by fire ; when she will lose her electricity and magnetism, (from over heat, as a magnetic needle will,) and, consequently, her atmo- sphere and motion, and be like the moon, a cold, dead body — a sort of balance-weight receiver of the surplus magnetism of the overcharged members of the system, and giving it to the negative as they approach her in their orbits ; — (" that time no man knoweth, not even the angels in heaven ;") — until after an " eternity," from the surplus moieties at times retained, her magnetism or life may be vicuperated, and iu proportion will motion on her axis return ; with motion, proportionate atmosphere will again come ; with atmosphere, humidity and temperature : — these will act upon, change and decompose the surface ; her eternity is passed — time and vegetation commence ; stinted and sickly shrubs, at first, as on she rolls, turning her equator to the sun, in time will become trees ; and magnetism is busily at work the while, assorting to their different spheres and places, the materials of the different rocks and metals, and preparing ingredients for living organic productions, perhaps only to he originated when the sun has no declination ; and when there would be no variation of the magnetic needle, from either " terrestrial " causes in changes of axis changing the lines of circulation of the fluid : or from " celestial " causes in the varied positions of the planets in their orbits, unequally charged : and which harmonious recurrence may have formed the Egyptian cycle of 30,000 years. Those who think Moses wrote of " the beginning " witliout under- standing his subject, or that Daniel spake without a mean- hig, can have little or no idea of the wisdom of the Egyp- tian magicians, (men of science,) whose store-house of science, learning the arts, was the pyramids, which, when opened 1300 years ago, contained innumerable specimens of now ( 77 ) lost arts, as " glass that would bend without being broken," — the written history of the world, " sealed up to the end" — a written out system of astronomy — the names of the stars, and how they moved in their courses — the various medicines and poisons, and how they operated. For a minute account of which, see " Description of the Pyramids of Egypt, by John Greaves, Professor of Astronomy, Oxford," published 1646 — which work is supposed to have originated with King James I., of England, called the *' learned fool," — who, while Prince, travelled in Egypt, Arabia and Persia, having with him Mr. Greaves, in whose name this book, containing descriptions, measurements and drawings of the pyramids, was published. But ! — my enduring reader, these are matters a long way from Lake Superior, and the Copper Mines, and this is a book of facts — not theories ; yet, if you shall find yourself next season, as a Tourist or Explorer, in that land of the " mountain and flood," where Summer's sunset hours are farther up the arch of night, than in the latitude you left, — if there, far from society and social haunts, by your camp- fire musing, or chmbing some mountain-peak, observe the stars wending their way through space, and then remember these suggestions upon the destiny of worlds — may they in- duce a wider range of thought, and ** Lead thy will submissive to great Nature's laws — Admire effects — and know they have a cattle. 7=^ ( 78 ) MISCELLANEOUS. WORKING COMPANIES. LAKE SUPERIOR MINING CO. Eagle River. Charles H. Gratiot is the a^ent and manager. This is the Pioneer Company in working, followed closely, however, by the Pittsburgh. This company have one shaft about one mile back from the river of eighty-five feet deep with drifts from it ; also five others of various depths from twelve to forty feet. They have a drift started into the hill from the bed of the creek at a lower altitude than most of their shafts, which may be made an adit if necessary in future. They have about thirty buildings in all upon their location, and one hundred and forty men and women, and children in numbers. They have a stamping machine driven by water, with sieves and washers attached. Their saw-mill is down within eighty rods of the lake. Piles of ore, esti- mated at twelve hundred tons, broken up, lay about and look like the prepared stone for McAdamizing. The veins are native copper disseminated, and silver is represented to be more than usually abundant in this vicinity, but in what degree or quantity over what is often found in metaliferous veins remains for working and extracting to determine. Great regularity prevails here, considering there is no law, and every thing manifests that energy, industry and capital are uniting their efforts. The width of these veins cannot be determined with accuracy — the whole depth of the deepest shaft showed but little or no demarkation, as the copper seemed distributed in all directions throughout the rock. This company have sent down 4,573 lbs. of extracted native copper. The amount sent forward is no criterion to judge their works by. They have made large expenditures and yet, although they have large quantities of broken rock ready for crushing, they did not get their machine ready till very late, and although it has cost dearly in transportation, &c., ( 79 ) it does not perform the work estimated or required. But improvements will continue to be made in all these matters, and ultimate profits, I doubt not, will pay present losses, emanating from a want of knowledge and experience in the business. The rock of these works is the amygdaloid, containing disseminated globules and leaves of native copper and silver. Sometimes silver and copper are found in the same globule. The vein is represented by Dr. Jackson to be eleven feet wide and traceable for a mile. It is my opinion that there is no clearly defined vei?i eleven feet wide — I think the whole rock of the vicinity of these shafts contains disseminated me- tals and may be worked, a circumstance, however, not pe- culiar to this particular place. I think the same fact exists on many of the neighbouring locations. But none of the locations are yet explored to any extent. The following statements of the richness and value of the Eagle River Ore, are from Dr. C. T. Jackson : — Analysis of 1500 grains of the Rock. — Silver from the metals, 114 grs. 49 pwt.'s; copper, 27.51 ; silver from the washed ore, 3.75 ; copper, 90.35. Amount of silver, 1 18.24 ; do. of copper, 162.86. Refined or pure silver obtained by reduction of the chloride 114.5 grs. The analysis above detailed gives the quantity of silver in a ton of the rock — 152.66 — valued at $20 per lb. av. $3,053 20. A ton of the rock contains 203.57 of copper, valued at 16 cents per lb. ; value of one ton of the rock, $3,036 77. The above was Dr. Jackson's first report. The following one was subsequently made, I believe at a session of Philo- sophers in New Haven : — In a ton of the rude ore as delivered by the miner at the pit bank on Eagle River there is the following per centage : Of silver ^87,25 Of copper 42,10 Total $129,35 And in a ton of the ore as delivered at Boston there is $568 worth of silver and over $200 worth of copper ; so that it is more properly a silver mine than a copper mine ; 17 lbs. 9 oz. of the clean metal was obtained from 50 lbs. of ( 80 ) the ore, by careful assay. 50 lbs. of copper ore gave 1 1 lbs. 4 oz. in large pieces of copper and silver, besides the wash- ings ; and an assay of that yielded 663 grains of pure silver, or equal to 25 2-lOths of silver to a ton of ore. PITTSBURGH COMPANY. The Pittsburgh Company is located at Copper Harbour, under the management of Dr. William Pettit, general agent for their several works in operation. —At this place, on Lease No. 4, on Lease No. 5, on the lake west of Eagle River, and on Lease No. 12, adjoining it. Lease No. 4 covers Copper Harbour, Porter's Island, and Manganese Lake. They have erected seven or eight good log buildings, including storehouse, blacksmith shop, «fec. The vein they are working runs west of south from the har- bour, where it first appears in the conglomerate at the water's edge, some eight feet wide of spar, and thence to Lake Fanny Hoe 80 rods south. Again it appears in the mountain oppo- site. Upon the high ground back from the bay some 50 rods, is a shaft 14 feet deep, which seemed to be on a branch rather than the vein, the ore in it being only five or eight inches wide, and inclining much to the west. About ten rods east- erly of this shaft, was one 34 feet deep, which was, instead of a regular shaft, a " fining up" of the crevice between the wall rocks, which pitched to the east. This opening was 20 feet long at top, and the walls approached at the time of their pitch within 18 inches of each other, but widened below ; rather a tight squeeze to pass in the ore tubs, although they were v/ell greased v/ith mud. The drifting belov/ is along this crevice, from which the famous black oxyde of the Pitts- burgh Co. is taken, and from which it is raised by "Jack" &. Co. for $50 per ton. Jack failing in his contract when- ever a " horse" comes in, and working by the month till it is removed, when he again contracts ; of which he informed me confidentially, as I was looking for a "job," which he took the liberty of inferring from my dress and use of miners' phrases, as well as willingness to go down in the "tub," which soft clothes and soft nerves are not prepared for. To be suspended in "a hole in the ground," 80 feet deep. ( 81 ) — to hear the chck of the hammers and drills below you, and have it seem as if you never would reach the bottom, and twice as long in going up, is rather squeamish at first, but "nothing when you get used to it." A third shaft, 80 feet deep, is 20 rods further south on this vein, at the bottom of which the "drift" is more west. In reaching this depth, red sandstone was passed for a considerable portion of the descent, and from thence the drifting for the vein, which was just beginning to yield again. A gang is also now at work upon probably the same vein a little west of south from this shaft, in the mountain side across the lake, where I think the work should have been begun, and all the expenditures made in driving " drifts" at different altitudes into the mountain's side, as this company's superintendent back of Eagle River, Mr. Jennings, is now doing. From the deep shaft it is 20 rods to Lake Fanny Hoe, which is very deep, and bold banks, probably a perpendicular wall, towards which, 80 feet from the surface, the south-westerly drift is progressing, and must there stop. Extract from Stockton's Report. ** A vein of copper has recently been opened on Keweenaw Point, near Fort Wilkins, which has already yielded several tons of ore ; specimens of which have been submitted to Dr. Houghton, state geologist of Michigan, who, by analysis, has found it to contain from seventy to seventy-four per cent, of copper. Specimens of the same ore have also been subjected to analysis by Dr. M'Clintock, assayer of the United States mint at Philadelphia ; and the result of the exami- nation appears from the following extract of a 1-etter from Dr, M'Clin- tock to William Pettit, M.D., who has kindly furnished it for my use : ' Having found leisure, since the receipt of your letter through Dr. Jones, to make an analysis of the copper ore from Lake Superior, to which it refers, it affords me great pleasure to transmit the result. ' 100 parts of the ore contains of — Silex . . 7-00 Metallic Copper 70-00 Oxygen . .17-50 C '^■R^ parh «niH { ^1*' according to Klaproth, Carb. Acid, &c. 5-50= J ^.°^ witer ^ ^'^^ carbonic acid, ^ ' (_V31 water. " The mass of the ore is a peroxide of copper, producing a rich blue colour with aqua ammonia, which the protoxide fails to do. The blue carbonate of copper constitutes but a small portion of the specimen, and seems to dip into its interior. The carbonates always contain a portion of water, and you will therefore find the latter estimated with the carbonic acid, &.C., 5-50 being the absent parts ; and no trace of sulphur having been discovered, they are assumed to have been the ( 82 ) • carbonic acid of the blue carbonate, and the water necessarily dissoci- ated with it. " I send you the pure metallic copper precipitated from a solution of 50 grains parts of the ore ; it weighs 35 grains parts, and is there- fore equal to 70 parts in 100. " The absence of iron, sulphur, &c., adds greatly to the value of the ore, by rendering the smelting much easier, and insuring a better article when smelted." Dated February 4, 1S45. Leases No. 5 and 12, belonging to this company, are on the lake shore immediately joining and west of Eagle River^ and under the sub-management of Mr. Joseph Hussey, who has commenced building, &c., on No. 12, but to what extent he has progressed I did not learn. The veins upon this location are said to be good, corresponding with those opened in the region east and back of them, on the other Pittsljurgh Lease No. 5, and Albion Lease No. 10. Lease No. 5 is under the sub-management of Mr. R. Jen- nings — is three miles back from Eagle River, to which a waggon road is made, which attains an altitude in tliis dis- tance of 300 feet above the lake Here arc fine substantial log buildings of good size, blacksmith and cooper's shop, &c. The vein is native copper, disseminated in amygdaloid trap, and runs perpendicular with N. W. and S. E. course or nearer, perhaps, N. and S. into a prrcipitous hill 300 feet high, upon the top of which the work was formerly com- menced with a shaft, but which Mr. J. abandoned on taking charge, and proceeded to open drifts at three different alti- tudes into the Iiill horizontally, which, when necessary, will be connected by ventilating shafts. The " offal rock" from these drifts is thrown off a barrow run, and the ore sent down in a chute. This vein was working very fine, three feet wide where I saw it, and presented appearances of being dissemi- nated throughout the rock. Ore sent produced 33,577 lbs. NEW YORK AND LAKE SUPERIOR MINING COMPANY. At Dead River, Agate Harbour and Eagle River, — Edward Larned is general agent, and Charles Larned i.<; the sub-agent and manager at Dead River. He has seven- teen persons, fifteen men and two women. These are Eng- lish and Irish. The overseer is a Cornish miner, who seems ( ^JJ ) to understand his business. They have erected five log- buildings, including a storehouse and blacksmith's shop, and a root house. Their buildings and shaft commenced, are on the north end of the point near the north bay, and on the west side of the river. Their shaft is opened considerably above the lake from which the hills rise back. Mr. Larned went on with his men about the fifth of October last, and had put up his buildings and worked but five days at the shaft, when I was there, October 28th. The shaft commenced here is upon a lead vein, from which they took three tons in the five days they had worked. The harbours of this place I have described before. The river is a rapid river, (not dead) affording beautiful falls and scenery in its course, a ad water power at hand, though for a short distance affording a good place for vessels, if the mouth shall have the sand bar removed. The country is hilly in the rear, v.'ith good valleys, furnishing maple, oak, ash, bass-wood, pine and birch. Of the two last they burn their charcoal. This location is represented by Professor F. Sheperd to contain copper and silver, but it has not been thoroughly explored. Adjoining this on the west, and belonging also to the N. Y. and L. S. M. Company, covering Presque Isle, is Lease No. 29. The rock is granite as at Granite Point, thrown up through the red sand stone which appears at Garlic River three miles west in cliffs, but generally forms the plateaus between the granite hills, which seem to have thrust them- selves up through it. No ores except iron and zinc are found in sand stone strata ; but copper is usually found m the granite above and at their junction. Same — Agate Harbour. — This place is also described iu coasting, and is covered by Lease No. 18, belonging to this company. The sub-agent at this i)lace is Mr. Marlet, and Mr. Hitchings conducts the mining operations. There are at this place twenty-five men, four women, a number of children, to which was added a native Irishman in the first week. They have erected since their commencement on the 29th September last, five commodious log houses, inclu- ding store house and blacksmith's shop, a root house or cel- lar above ground, twenty-four by sixteen, and sunk one shaft ( 84 ) forty-five feet, and another twenty-two feet. The buildings and vein are on the outer neck of land, or conglomerate rock which covers the eastern end of the harbour, near half a mile from its extremity. The vein was opened at the lake bank, by sinking a shaft, which is the forty-five feet one. The spar vein of the surface was about 18 inches in width at starting. The spar continues to its present depth, afford- ing a green sulphuret. The wall rocks have gradually divi- ded since passing the conglomerate of the surface, and which filled the depressed line of the vein. Quantities of what is termed the mother of ores has been raised, with green and black sulpheret and spar. About thirty rods S. W. from this shaft another is sunk upon the vein at a point where an E. and W. vein intersects. The conglomerate was passed at about nine feet, and the wall rocks of the two veins were but a few inches apart, in which was again found the mother of ores, green sulpheret and spar together ; and when down twenty feet the wall rocks began to separate, and a black sulpheret was found. The E. and W. vein being about ten inches, the N. and S. about five at this point, we took a double handful of the black sulpheret, which was of dark marly appearance, and hke black earth, which we put in an iron melting ladle sat upon the forge fire and covered over with charcoal ; it melted and poured off (what did not escape through the pores of the ladle,) yielding a piece of copper the weight of a cent. From this, others can judge its rich- ness as well as I can. They have here two cows, pigs, poultry, and all that is necessary for pushing their works rapidly. There are several veins on this location, and two shafts have been sunk on a vein running into the liill across the bay, but which were abandoned on commencing opera- tions on the penisula. I think this last vein, which is in the trap rock, might be traced to the neighbouring hills, and worked by drifts to greater advantage than putting down shafts on the low altitudes. This, like all of the other loca- tions of this company, has not been thoroughly explored. Even Shooneaw Lake, one mile back, is diflionlt to find. Lease No. 31, on Eagle River, belongs to this company, and is under the sub-agency and management of Mr. Bur- chard. This location is on the east branch of Eagle River, and the wagon road from Eagle Harbor to Copper Falls has ( 85 ) been exteiidecl west to Mr. B.'s place of operations. He went on with supplies and fifteen men on the 12th Oct., and on the 25tli had his road made and buildings well advanced. The works on this location will be in the same range of trap hills with the Copper Falls' works. This company also hold Leases No. 3'2 and 17, which are next south of Copper Harbour, and bordering on the south on Keweenaw Bay, and through which the Little Montreal river runs to the Baye Bris. Neither these nor their other Leases, Nos. 19, 22, 23, at the mouth of the Montreal River, are yet worked. THE ISLE ROYALE COMPANY. Cyrus Mendenhall is agent and manager. They have Leases Nos. 16 and 27, east from Copper Harbour, which is No. 4. Mr. Mendenhall has been at work nearly the whole summer, with from four to seven men, and now has ten. This location is composed of conglomerate ridges next the lake, with granite breaking through in small knobs and hills. He has three small buildings near a little land-locked boat harbour cut in the conglomerate shore by the action of the lake. He has sunk at this place a shaft forty-five feet deep in the trap rock, obtaining some green sulphurets, but on the whole thus far without finding any quantity of value, but a gradual increase in the indications as the shaft descends, and which undoubtedly would lead to ore, but at what depth, perseverance alone can determine. While I was at Copper Harbour, a new vein of native copper was brought to Mr. Mendenhall's knowledge by a soldier of the garrison, on the award of Col. Todd and Capt. Albcrtis, who gave the sol- dier, after examining the vein, for finding it, $50 cash, and $500 to be paid from the first product of the vein. This vein I examined in company with Mr. Mendenhall and Geo. N. Saunders, Esq. The native copper makes its appear- ance in a thin sheet widening inwards. Its outer edge was the eighth of an inch, but I have a piece broke out with a hammer, three-fourths of an inch. It presents itself thronjrh a crack or vein in one of the trap knobs of a hill, 100 rods south-west from their present works, which comes through the conglomerate covering of the surface of this vicinity. 8 ( S6 ) This vein Mr. M. intended to commence upon as soon as he could erect his permanent buildings, which he is doing near the eastern extremity or arm of Copper Harbour, on an inlet of which he has this season raised potatos, turnips, &.C., and which will produce good hay. This company have also Lease No. 17, v/hose north-east corner joins the south-west corner of Lease No. 4, (Copper Harbour) which is a very hilly location, and its south-east corner cuts upon Kewee- naw Bay — Lease 24 which is seven miles up the Montreal River, Lease 25, five miles up the Montreal River, Leases 28 and 29, on the Montreal ; for these locations men with provisions went up very lately, merely to hold and " pros- pect." V EAGLE HARBOUR COMPANY. At Eagle Harbour. This Company's location is on Lease No. 3 ; Mr. Sprague is Agent and Manager of the work. He has twelve men — has been lately erecting buildings, and preparing for future operations. The vein is in the Trap River, immediately on the South shore, 100 rods west of the Harbour. Here are two or three shafts, and the deepest is 33 feet, in sinking which, he thinks he has obtained sufficient ore to pay for the work. The product is native copper dissemi- nated in trap, and similar to that obtained at Copper Falls three miles back. Mr. S. has all that is necessary to pro- ceed vigorously with his work this winter ; there is a good water fall one mile back. They are intending to lay out a village plat here next spring, and erect a public house. It is a first rate harbour, and a beautiful site for a town. This place will probably do the commercial business for the adja- cent country, including Eagle River. THE COPPER FALLS COMPANY. Mr. Childs is Agent and Manager of this work. Their location is Lease No. 8. It is three miles, and a good wagon road, back from Eagle Harbour. Mr. C. has erected six log buildings. He has turned the course of a small stream, ( ^' ) and commenced on the vein in its bed, drifting into a liill on an altitude of 100 feet from tlie base, and, I suppose, 300 feet above the Lake. The product of this vein, which is two feet wide, is native copper disseminated in amygda- loid trap. The spar, and other similarities, would indicate it the same vein that Mr. Sprague is working at Eagle Har- bour, or the one being worked at Grand Marias, by the North Western Company. It is from this place the road is continued by the New York Company, to their works on Lease No. 31. THE BOSTON COMPANY. Two miles East of Agate Harbour. Joseph Hempstead is Agent and Manager of their works, which are on Lease No. 15. This lies upon the Lake shore, next east from Agate Harbour. He has erected five first rate commodious log buildings, and has a force of twelve men. His buildings are two miles east of Agate Harbour, and 100 rods from the Lake. The land falls from his build- ings south to a beautiful little Lake, half a mile long, eighty rods wide, at each end of which, up and down the valley, are fine Ijeaver meadows of black alluvial deposit. One mile west from his buildings is a native copper vein, from which, next the Lake, was cut and blasted oif a piece of pure copper, which lay on the bank when I was there, weigh- ing probably 800 pounds, and another of 60 pounds ; the first was three feet long by eighteen inches wide, and eight inches thick. It was rather an oval form, and the wide end thickest. This Company also own Leases No. 13 and 14, on the south-eastern extremity of Keweenaw Point, but are not working them. There is a most perfect natural road from this place to Agate Harbour, running upon a conglomerate, flat ridge, smooth and level. BOHEMIAN COMPANY. Back of Agate Harbour. S. Mendlebaum is the Manager and Agent of this Com- pany, which is working on Lease No. 35. The location ( 88 ) joins its nortli-west corner to the south-east corner of Agate Harbour. The works of this Company are on the head waters of Little Montreal River, in the amygdaloid trap, about half a mile south of Musquito Lake — a Lake two miles long, with a handsome island in its east end. He had a company of men, on the 20th October, making a road to Agate Harbour, and putting up buildings, and making preparations for winter's work. Ore taken from the vein at the first blast, is certified by Dr. C. T. Jackson to yield twelve and a half per cent, cop- per from the crude rock of the vein ; which, he represents, as similar in all respects to the veins of the Eagle River vicinity, except that the globules are fewer and larger. NORTH WESTERN COMPANY. At Gi'and Marias Harbour, Mr. Bailey is Agent and Manager for this Company, which is located upon the peninsula, on the eastern side of Eagle Harbour, which also forms the west side of the Grand Marias Harbour. Mr. B. had just commenced his buildings on the east side of the peninsula, when I was there on the 18th of October. He had seven men, and provided with all the necessaries to proceed to mining when his buildings should be finished. The vein on which operations will be commenced has been opened with blasts, and looks well upon the surface. The mineral is the native copper dis- seminated in the trap, as upon the west side of Eagle Har- bour. Its width appears about the same. The fact is, it is very difficult to determine the width of these veins of native copper disseminated, for throughout this whole region, the dissemination extends into what is generally called the wall rock, while the spar and vein stones in the conglomerate define the width. Half a mile back from Grand Marias, is Island Lake, which is one and three-quarters of a mile long east and west, and a half to three-quarters of a mile wide, with an island in it formed of conglomerate rock, and bearing a few- trees I have left off the mineral map, the dividing line between ( 89 ) the west line of Lease No. 18, and the west line of Lea^e No. 9. My reason for so doing, is that there is a claim be- fore the Commissioners for the Grand Marias, or a strip covering the vein, which is resisted by the Eagle Harbour Company. I am satisfied, by walking from Agate Harbour to Eagle Harbour, that there is surplus lands between these lines ; but the difficulty originated in measuring from Cop- per Harbour to Agate Harbour, and then from Eagle River to Eagle Harbour, without closing the work between these points. THE SUPERIOR COMPANY, Adjoining Copper Harbour. George N. Saunders is manager and agent for this Com- pany. Their location is Lease No. 1, and next west adjoin- ing Copper Harbour. There are to be seen several distinct spar marked veins, in passing this location in a boat. Mr. Saunders was preparing buildings, and had men employed for winter operations. From one of them, upon whom I can rely, I am informed the veins " prospected" upon afford excellent specimens of native copper and ores, with. indica- tions of large quantities. ALBION MINING COMPANY. Three miles south of Eagle River. This Company have Lease No. 10, which is cut by the west branch of Eagle River, and a stream falling into the lake on the west. The location covers and gives name to the Albion Rock heretofore described. They have con- tracted for the erection of buildings and opening the road this winter, from Jennings' works on Lease 5, intersecting his road to mouth of Eagle River. NORTH AMERICAN COMPANY. West of Eagle River. John Bacon is agent of this Company. Their location is on Lease No. 7, which, like those of the previous described 8=^ ( 90 ) working companies, is a three miles square permit. A west branch of the Eagle River runs through it. Their place of operations is two and a half miles west of the mouth of Eagle River, and their vein is, like all the others of this vicinity, native copper disseminated. He had a force of ten men, and was preparing his buildings on the 15th of Oc- tober. CHIPPEWA MINING COMPANY. On the Ontonagon and Eagle Rivers. This company is located on the Ontonagon and Engle Rivers, as I was informed by their agent at Copper Har- bour, Mr. W. H. Morell, and which I find reiterated in the following extracts from a very interesting article of that gen- tleman, published in the New-York Courier and Enquirer. I have made an exception in this case and put down the Chippewa Company as a working company upon his and the following representations. The others I speak from per- sonal visit and knowledge of The article alluded to in speaking of the Ontonagon River says : — " In the last eight miles of its descent to the Lake, it falls at the rate of one hundred feet or more to the mile, laying bare the trap rocks which there form its bed, and exposing to the explorer the veins that traverse them. Here numerous veins containing copper have been found, most of which have been covered by permits belonging to the Chippewa Mining Co., and in proving which they have a force now at work whose operations will be continued through the winter. *' At the promontory forming Keweenaw Point, the course of the veins is from ten to twenty-five degrees south of east ; higher up the Lake, at Black River, and other lo- calities, their course is as much, and oftener more, west of south. These veins vary in width from a mere hne to several yards, and their mineral contents, whether of silver or cop- per, are for the most part found in a native state, although in a few instances the sulphurets, and other rich ores of cop- per^ have been discovered. But it must be recollected that but comparatively little of this region has been exposed to ( 91 ) the explorer, and it is reasonable to expect that other veins, perhaps of greater extent and richer in quality than those now discovered, may yet be developed." The last extract corroborates not only my own observa- tion, but the representations of nearly all explorers of the Lake Superior Mineral regions, that the great preponderance of copper is found in the native state disseminated which all analyzers thus far acknowledge, is unalloyed with other metals.
