That after maturity the relative amounts ami proportions of the ehief factors vary but little, even for a period of three months or more, provided the season does not change: e. acres planted May 4-6; 2^ acres planted May 7; 71 acres planted May 8-10; 12 acres planted May 17-28. The 12 acres were of the Honduras variety, and the remainder con- sisted of 51 different varieties. He says he was continually replanting and filling in the rows, until about June 15. At that time, notwithstand- ing all his efforts, at least £ of the land had no stand. The department paid him a rent, $12.50 per acre for the land for the season, and for all the labor employed on the crop. He delivered from his 28| acres 105 tons of sorghum, the entire crop being 110 tons. This crop cost the go vein men t $1,367.25. The land of Dr. Dean resembled that of Mr. Golden. It consisted of 40 acres, rented and managed in the same manner as the preceding. He began planting May 20 and completed the -first planting May 25. From that time until duly 15 he continued to replant. At this last date, as he reports to me, a crop of Early Amber was planted, which was ripe on September 15. He delivei ed 50 tons to the depart inent, and the rest was frost-bitten and rotten in the field. This crop cost the govern- uicnt $2,000. TEE SORGHUM SUGAR INDUSTRY. 11 The laud rented of Mr. Carlisle Patterson, consisting of about 65 acres, was divided into two lots, according to the statement of Mr. Cul- ver who had charge of it, one of which was planted with Early Amber, and the other with "Link's Hybrid." On Tuesday, May 10, the planting of this land commenced, and the work was renewed until Juue 18, when it was planted for the third time. The land was a pasture which had been heavily fed for years, and was plowed just before planting. Y~ou will not be surprised to learn from Mr. Culver that the first " lot of seed was nearly all destroyed by worms" on land like this, and that the worms continued their ravages until they were driven away by rolling the seed in coal-tar. The amount of caue delivered to the department from this land was about 100 tons. The cost of this crop to the gov- ernment was about $4,000. No manure or fertilizer of any kind was used on these parcels of land, either on the worn-out pasture which was filled with wire-worms, or on the old laud which had been previously cropped. The land of Mr. Patterson was a light sandy loam. This agricultural operation should be seriously considered. Mrs. Glass in her famous English receipt for cooking a hare commenced by saying, "First catch your hare." To those interested in the sorghum industry, whether on the land or in the mill, the foremost injunction is " First get your crop," by the exercise of all that wisdom in the selection of land, and the modes of fertilizing if necessary, and the care of the crop, which enables the farmer to raise the great corn crop of the West, and the valuable special crops of the East. On the ninety-three acres harvested, the yield was about two and a half tons to the acre. The yield of sirup and sugar from this was small. The result in the large mill and in a a smaller one devoted to special processes was very unsatisfactory. 1 should say the lesson learned from all this was what to avoid and not what to follow. To the farmers it gave so poor encouragement, that when I endeavored to employ them to raise a crop for the work of the present season, one of them experienced in the efforts of last year pro- posed to raise it for me at $15 per ton, and an inexperienced one pro- posed to raise it for $6, and finally concluded that he had better not raise it at all. At this stage of the proceedings, having satisfied myself that the experience of practical men endeavoring to work to a profit, was especially necessary for the development of the industry, and that a judicious selection of locality is necessary for this as for every other industry, I called upon the manufacturers throughout the country to contribute the results of their experience during the present year. To a circular issued by me in June last, calling upon them to furnish me information upon their various modes oi manufacture and the results, I have received nearly a hundred responses, and I feel confident that much valuable knowledge will be compiled from these communications. I have also secured from other sources accounts of work now going on, which 1 feel confident will be interesting to this association. In the report of the Academy of Sciences to which I have alluded, I 12 THE SORGHUM SUGAR INDUSTRY. find many references and opinions with which you are all familiar; and I also find elaborate statements of work performed (luring - this last summer and autnmn to which I call your attention, as the most recent information we have upon this subject. The committee having in the firs! draft of their report presented the condition of the Rio Grande Sugar Company in 1882, state, under date of October 12, 1882, that they are able to add the following information obtained by a personal examination of the plantation and sugar works of this establishment. They say: This company (the Rio Grande Sugar Company, Cape May County, New .Jersey,) are the present owners of their works, anil also of 2,400 acres of land, chiefly of a light and not fertile soil, being on the peninsular between Delaware Bay and the sea, within live or six miles of Cape May and 75 miles south of Philadelphia. April 19, 1882, and following, they put in, of Amber cane, 958 acres; Linke's Hybrid, 25 acres; Early Orange, 23 acres; and Honduras, 2 acres; in all, 1,008 acres. Warned by former ex- perience the company determined to own ami cultivate its own cane. The very cold and wet spring occasioned the loss of a considerable portion of the first planting, the loss being also due in part to deep planting by unskillful hands. The deficient portions were replanted in June, leaving such portions of the first planting as came up to grow together with the second planting. This circumstance worked consider- ably to the injury of such portions of the crop, and reduced the exponent of sugar notably. Notwithstanding this untoward circumstance the ciop, as we first saw it. near the close of September, presented a noble appearance of vast fields of luxuriant cane ready for the rolls, and still full of vigor and of a deep green color. The Amber cane stood about 8 to 10 feet in height; the Orange and Linke's Hybrid were higher, being from 12 to 14 feet. The Amber cane only was ripe at that time, and the harvest- ing had been in progress from the 28th of August, at the rate of 120 to 150 tons of the cane delivered daily to the mill, which is the present limit of the floors to accommodate the sugar wagons. The mill is a powerful apparatus of three rolls, each 5 feet long and 30 inches in diameter, driven by a steam-engine of 125 horse-power, crushing the cane with an opening of only one-sixteenth of an inch between the rolls. The stalks are uot stripped, only the dead heads are removed in the field. This mill is capable of crushing 300 tons or more daily, but the floor space of the works limits the out- post, as before stated. The product of sugar exceeds the most sanguine expectations of the projectors. The Amber cane, on a large area, stands not less than 10 tons to the acre on about TOO acres. The exact figures for the whole crop can be given only when the account ] s fully made up. Each day's cutting is accurately recorded, and so can now be safely stated. We saw the "strike" of the vacuum -pan of 1,600 gallons on the 28th of Sep- tember, and again on the llih of October, filling nine, wagons of one ton capacity each with "melada," yielding 2.1 or 3 barrels of sirup to the ton, The yield of sugar to the wagon would be, by estimate, greater by about half a 'barrel (the barrel holds 355 pounds) if more time could be allowed for it to stand before going to the centrif- ugals. From the mill the green juice Hows to a tank of 1,000 gallons capacity, whence it is pumped to defecators, after which it is hurried through the open pans to the vacuum- pan, where it is reduced to about 32 !>.. and thence to the Larger pail of 1,000 gallons, where it is raised to about 45° B., or a temperature of about 140 F. There are two "strikes" of this pan daily. The lack of space for cooling compels, at present, the working of the melada in the centrifugals, of which there are four, before it is com- pletely cooled, so diminishing. as just stated, by probablj a half barrel, tin' yield of *• firsts." We examined the books o Henry A. Hughes, the superintendent, who is a sugar boiler THE SORGHUM SUGAR INDUSTRY. 13 of twenty years' experience, which showed the juice of the daily workings, as tested hy polariscope, to have a coefficient of from 10° to 12° for the new juice, which is polarized several times daily. For the week ending the day of our first visit 656 tons of cane were crushed, yielding 115 barrels of sugar of 88°, and 89 barrels of mo- lasses of 47°. The first sugar was equal to 63 pounds to the tous of cane crushed. The fertilizers used on the laud of this plantation this year were about 25 bushels of lime, followed by 150 pounds of Peruvian guano, having as much sulphate of ammonia added as raised the nitrogen to 8 feet. This guano cost $53 per ton. A few acres were treated as an experiment, with fair results, with barn-yard manure; on about 20 acres fish guano alone was used, the effect of which was to reduce the available sugar by about l c on the polariscope. On the whole, the lime, the guano, and stable manure gave good results. Greeusand marl, which abounds in New Jersey, remains to be tested hereafter. The crushing of the cane with the leaves settles one of the "sor- ghum questions" on which there has been much difference of opinion-. In practice, on a large scale, the removal of leaves would involve an impracticable amount of labor. In the 1879 Report of the Department of Agriculture, p. 59, are experimental results showing an increase of both juice and sirup from the crushing of the entire plant (seed excepted). A small loss of available sugar and a gain of sirup will prob- ably result from crushing the blades with the stalks, a subject requiring further exami- nation. It is by no means improbable that in the plant's life the sucrose is elaborated directly in the leaf, and is gradually transferred to the stalk, where it accumulates. The fall returns for the crop of this year will not be in before the closing of this report. But we are able to state from a communication of date November 8, 1882, from the president, that the probable results of the season's work ending November 11 are as follows: 6,000 tons of cane, 950 barrels of first sugar, and 1,100 barrels, 50 gallons each, of molasses. The seed is not yet measured, and a full balance sheet re- mains to be made up, which may, perhaps, come in season to be added to this report. The Orange cane turns out rather better than the Amber, being richer in juice, and with an average test of 13° B. This committee have received from Mr. Knight, the sugar refiner of Philadelphia, a barrel of the sugar, sample of a lot of 350 barrels refined by him, of the Rio Grande Sugar Company. It. ranks, .on the independent judgment of experienced growers t© whom we have shown it, as " C" sugar. Analyses of the soils of different fields are now in progress to determine, if possible, the causes which influence such very unlike productiveness as the experience of the season of 1882 has shown to exist — the differences of yield being per acre : 3| tons with guano and no lime; 5^ tons with guano and no lime; 7i, 8, 15, 17 tons respectively. Since the completion of this report of the Academy, I have received the following statement with regard to the product of these works in 18S2: sugar, 319,000 pounds; molasses, 40,000 gallons. It will be observed that no reference is made in the report to the methods employed in the manufacture of the sugar. It is to be pre- sumed, therefore, that they are such as are usually employed in the pro- duction of cane-sugar. The committee of the Academy have also laid before me an interesting statement of the Avork of the " Champaign Sugar and Manufacturing Company," Champaign, 111., as follows: The undersigned have the honor to present to you the following report on the man- ufacture of sorghum sugar for the year 1882. Our report is necessarily incomplete, as we are still in the midst of our season's work ; but the gratifying l'esults thus far obtained will, we hope, warrant our reporting the data on hand. HENRY A. WEBER. MELVILLE A. SCOVELL. Champaign, III., October 28, 1882. 14 THE SORGHUM SUGAR INDUSTRY. As a result of the experiments carried on l),v the writers in the seasons of 1880 and 1881, the Champaign Sugar Company of Champaign, 111., was organized. The ohject of the company was to carry out, on a commercial scale, the production of sugar from sorghum, as was indicated by the laboratory experiments. The company was organ- ized with a capital stock of $25,000. The total expenditure for building the works and raising the crop, however, was more than $30,000. The main building is 40 by (in feet, and three stories high, with a lean-to, 4. r > by 30 feet, covering'the engines and Crushers. Near the main building are situated the boiler-house, with ninety horse- power boilers, and a kiln with twelve retorts for revivifying the bone-black. For the sake of convenience, the description of the apparatus will be given in con- nection with the process followed in the manufacture of sugar and sirup. The cane is conveyed by means of a carrier fifty feet in length, to the first mill, a "Cuba" No. 4, manufactured by Geo, I. Squier, of Buffalo, X. Y., who kindly consented to the use of his rubber springs for our second mill, which was originally one of the rigid kind. After leaving the first mill the begasse is moistened with a spray of hot water, and is conveyed by means of an intervening apron to the second mill. By the use of this second mill the sugar which is left in the begasse after passing through a single mill, as is pointed out in the report of our experiments, is practically all recovered. The juice from the two mills is pumped together to the juice-tanks, which are placed at the top of the main building, and have a capacity of about 3,000 gallons. From here it is drawn to the defecators, where it is exactly neutralized with milk of lime in the cold, heated to the boiling-point, aud thoroughly skimmed. These defecators are made of wood, lined with galvanized iron and supplied with copper coils for heat- ing. Four of them have a capacity of 660 gallons each, and one of over 1,300 gal- lons. After settling, the juice is allowed to run into the evaporators, where it is con- centrated to a density of 25° BaumC. The evaporators are two in number, eight feet in diameter, made of copper, and supplied with copper coils. From the evaporators the liquor runs into settling-tanks, and next through bone-coal filters. The filters are four in number, 2 feet in diameter, and twelve feet high. The liquor is next drawn up into the vacuum-pan, where it is concentrated to melada. The crystallization of the sugar takes place in the vacuum-pan, and could at once be run into the mixer and centrifugals. Owing to the fact that only one centrifugal has thus far been sup- plied, the strikes from the pan are usually run into crystallizing wagons and placed in a warm room until the sugar can be ''swung opt." There are fifty of these wagons having a capacity of 120 gallons each. The quality of the sugar produced is unobjectionable in regard to taste and color. It grades as extra yellow "C," and sells readily at the factory at 8^ cents per pound, in lots of five barrels. The molasses is of a dark color, but still is rich in cane sugar. It is stored up in barrels and will be kept until the cane is all harvested, when it will either be refined or worked over for a second yield of sugar. * The company raised 100 acres of cane, 8 acres of which is '• Kansas Orange," about 10 acres "Early Orange," and the rest "Early Amber." Private parties planted about LOO aires more, all of which was Early Amber, with (he exception of one field of Early Orange, containing 12.1 acres. 'fhe company began working up their Amber canes on September 21 . An analysis of the juice was made with t he following result : Specific gravity, Ihix 1 18 Cane sugar per cent .. 8.10 < rrape sugar do. .. 3.63 The best Amber cane of the company was grown on sod ground, the field contain- ing •")(! acres. The c position of t he \ u ice of th Ik field on October 21, was as follows : Specific gravity 1.060 Cane sugar per cent . . 10. IT < rrape sugar do. . . 2. I- THE SORGHUM SUGAR INDUSTRY. 15 Owing to the lateness of the season, one continuous run was made, and the cane raised by private parties was worked up with the company's cane, so that it will be impossible to give the yield per ton and acre before the close of the season's work. One field of Early Orange, grown by Mr. J. G. Clark, has been harvested .by itself and the products kept separate. Of this field and variety of cane, exact data can be given. The composition of juice, October 24, was as follows : Specific gravity 1. 070=16°. '.i Brix. Cane sugar • per cent . . 10. 82 Grape sugar do :!. 54 Number of acres in field, 1225. Total amount of cane stripped and topped tons . . 156 Yield per acre do . . . 12. 5 Amount of juice gallons. . 20, 939 Weight pounds.. 185,947 Per cent 59. 6 Weight of melada pounds. - 25, 920 Weight of sugar do 9,900 Weight of molasses do.. .. 116,020 Quantity of molasses gallons.. 1, 456 Yield of sugar, per acre pounds.. 790 Yield of molasses, per acre gallons . . 116. 5 In this statement the amount of water added in moistening thebegasse before pass- ing the second mill has been deducted from the total amount of juice obtained. The melada obtained from the Amber caue is fully as rich in sugar as that obtained from the Orange. The yield of sugar and molasses, per acre, will be lower for some of the fields of Amber, but for others it will be fully as high, and in a few cases per- haps higher. It is not more than fair to add that for this section of the country the season has been very unpropitious for the proper development of sorghum cane. This will be seen at a glance by comparing the analysis given here with those made in this locality last year and the year before, as given in our report. The necessary hot summer temper- ature for the production of a high percentage of sugar was entirely wanting. But on the whole, the sorghum sugar industry is to be congratulated, for this cold, wet sea- son, as the flattering results which we are, nevertheless, obtaining here, will forever silence the claim that sugar can be made from sorghum only underthe most favorable circumstances. Since the above account was reported to the Academy I have seen it publicly stated that this company has produced about 125,000 pounds of sugar and 22,500 gallons of molasses during the last season. They estimate the return at $75 per acre. Valuable statements have also been made with less detail than those I have fully laid before you, by Mr. Magnus Sweuson, of the University of Wisconsin, for the year 1882; Capt. E. Blakesley of the Faribault Refinery, Minnesota, for the year 1881; Mr. John B. Thomas, of the Crystal Lake Refinery, Illinois, for the year 1881; Mr. A. J. Russell, Janesville, Wis. ; all of which have been submitted to me by the Acad- emy. The following letter from Mr. Henry Talcott, president of the Jeffer- son Sugar Manufacturing Company, Ashtabula, Ohio, addressed to the 1G THE SORGHUM SUGAR [NDUSTRY. Department of Agriculture, 1 also find in the appendix to the report of the Academy. Mr. Talcott, under date of November 2, 1882, says: I have been endeavoring to .scenic a praci ieal method of producing the same results which tnej have obtained at the Rio Grande Company's works, where I have jusl been for myself — that our farmers could all adopt with small means, and make the industry universal. I think our company can show the world as comnlete success in about four weeks as the Rio Grande have done, on a much smaller and more simple scale. We are now crushing and boiling from ten to fifteen tons of cane stalks daily : Uave been doing this lor tour weeks past : our returns, in yield, are the same in sub- stance as the Rio Grande; but, unlike them, we have had ten or fifteen good hard white frosts, some of them hard enough to freeze ice on water thick as window-glass. Our cane was standing in the fields; we are yet cutting it. 1 had ten acres of it on my own farm. We see no ill effects from it (the frost) in our work. We have made just as good a yield of juice: it makes just as good sirup and sugar, and all we have lost, as far as we can discover, is the Leaves for our cattle fodder. Mr. G. ('. Potts wished me to notify you of this fact on my return home: also to send von some samples of our work. We cools in open pans, by the Stewart process, only much more perfect than he ever did his work (excepl in theory). F. C. Knight analyzed our mush sugar and finished sugar yesterday, in their refinery, and pronounced it the purest and best sugar they ever saw. The sugar was our "second." This year's stock is still in our hot-room granulating slowly, for we dare not cook it dry in open pans, for we are so liable to scorch it when near done, 80 we make time and warm room dO part of the work. We shall not use our centrifugal until the close of the month; shall then have from sixty to eighty thousand pounds of mush to work over. I shall make a complete and clear report of it to the department as 1 possibly can. I shall also visit the Champaign Works in Illinois next week and compare notes with them. 1 have an invitation to do so, and must see the bottom of this industry so far as it is practically developed. Of course the vacuum-pan and animal-bone filter make the refined sugar at once ; a specimen of it they sent me yesterday, and I in- close a little of it for you : but this expensive machinery, if it is more profitable, can- not be made to come in general use. < >ur farmers must do this work as handy as they can make good butter and cheese, to get them into it in anj great numbers. Our fac- tory are learning many of them to do the work, and several others are to-day making mush sugar at their own molasses factories, while we furnish them solution B. and do their centrifugal work. I will send a little sample of sugar we purged yesterday for Mr. 1'. A. I'pp, of Edgerton, Williams County, Ohio, who made it under our direc- tions, and then brought to the factory to sec our works, and with his own eyes see finished sugar of his ow n make. 1 guess he was as well pleased with the result as any fond mother could well be with Inr first born, lie ret uriied home with his sugar, and said he should now go shouting among his own people, for he had accomplished well what his people all said was an impossibility. The committee of the Academj state in this connection: It is from t lie States of New Jersey and 1 llinois 1 hat we are able to cite examples of success on so large a scale and attended with such an unequivocal result as fairly puts to rest any doubts as to the production of sugar on a great scale in a northern cli- mate with a commercial profit . Hence it is thai I have quoted the reports from Rio Grande and Champaign. These significant communications adopted by the committee of the Academy I present here for your consideration. I regret that 1 cannot add statements from manufacturers who will soon supply the Agricul- THE SORGHUM SUGAR INDUSTRY. 1? tural Department with reports covering the following points submitted to them in my circular of June 6, 1882, viz : 1.

The replies I shall receive to this circular will be published as soost as they can be properly arranged, and I doubt not they will contain a large amount of valuable and interesting and accurate information. It will, I doubt not, be gratifying to ascertain the extent of the sor- ghum industry in the country; and I have endeavored to arrive at this as far as possible by means of circular letters addressed to correspond* ents in every county in the Union. I have received imperfect reports from the following States, and I submit them in this connection, not as a complete return, but only as indicating to a certain degree the extent of the industry. During the season of 1882,24 couuties in Arkansas have produced 729,500 gallons of sirup, and no sugar, as returned ; 12 counties in Alabama have produced 520,125 gallons of molasses and j>i> sugar; 5 counties in Dakota have produced 139,648 gallons of molasses and no sugar; 42 counties in Georgia have produced 508,023 gallons of molasses and 5,150 pounds of sugar; 35 counties in Indiana have pro- duced 018,410 gallons of molasses and no sugar; 32 counties in Illinois have produced 000,633 gallons of molasses and 13,200 pounds of sugar ; 38 counties in Iowa have produced 491,949 gallons of molasses and 731 pounds of sugar; 32 counties in Kansas have produced 950,947 gallons of molasses and 100 pounds of sugar ; 35 counties in Kentucky have produced 853,700 gallons of molasses and no sugar; 10 counties in Louisiana have produced 81,800 gallons of molasses and no sugar; '>7 counties in Missouri have produced 1,408,350 gallons of molasses ami 2,400 pounds of sugar ; 22 counties in Minnesota have produced 267,483 gallons of molasses and 100 pounds of sugar; 16 counties in Michigan have produced 46,503 gallons of molasses and no sugar; 15 counties iu Mississippi have produced 530,100 gallons of molasses and 2,200 pounds of sugar; one county in Maryland has produced 1,200 gallons of mo- lasses and no sugar; 2 counties in New Jersey have produced 42,000 gallons of molasses and 319,000 pounds of sugar; 8 counties in New York have produced 101,261 gallons of molasses and 90,150 pounds of 7248 2 M 18 THE SORGHUM SUGAR INDUSTRY, wgar: 1!) counties iu Nebraska have produced 177,420 gallons of mo- lasses and 00,000 pounds of sugar; 20 counties in North Carolina have produced 371,300 gallons of molasses and 1,500 pounds of sugar; 1'.' counties. in Ohio have produced 201,555 gallons of molasses and 275 pounds of sugar; 1 county in Pennsylvania has produced 1,200 gallons of molasses and no sugar; 6 counties in South Carolina have produced 292,500 gallons of molasses and no sugar; .">L counties in Tennessee have produced 2,122,700 gallons of molasses and 50 pounds of sugar; 47 counties in.

You will observe that this is but a small number of the counties in the States enumerated, and that undoubtedly some of the best sugar- producing counties have been omitted. The census of 1880 thus far contains accurate statistics from only four States, viz : States. Acres. Sugar. Molasses. Pounds. Gallons.

There seem to be several methods by which ihe desired result can be obtained, the choice of which is to be governed by soil, climate, and atmospheric influences. The condition of the ciop depends, of course, on the state of the soil in which it is grown. The conversion of the crop into sugar depends upon tlif skill with which it is harvested and subjected to the various methods of manufacture — methods which may perhaps differ somewhat in differ- ent localities. 1 am informed by one of the most intelligent investigators that the attempt of chemists in many localities to eliminate the acids which inter- fere with the successful manufacture of sugar and of clear free sirup alike have been crowned with success during the present season. He is of opinion that the work requires '-the constant attention of the chemist schooled to this particular work," and he suggests that "the sorghum, factories now without a certain knowledge of the juice in all its stages will fail to produce sugar in any certain quantities." Thisob- THE SORGHUM SUGAR INDUSTRY. 19 server's views of tlie prospect of the business in Kansas, Minnesota, Wisconsin, and Illinois are encouraging. I have of con rs% spoken, gentlemen, not as an expert in this matter, but as an observer whose official duty it is to encourage every branch of agriculture in our country, by wise co-operation with those who are engaged in the work of tilling the soil. The fact that sugar can be made from sorghum has been proved. That it can be profitably made Professors Weber and Scoville have demonstrated, and have so declared to this association with their fig- ures before them. That there is a market for the product no man doubts. Whether it is a universal crop or not, time and experience alone can prove. When I asked Professor Weber, yesterday, "What are the ob- stacles Professor Goessmann found in Massachusetts which render sor- ghum sugar-making there impracticable?" his reply was: "Shortness of the season, danger of early frosts, and an incomplete development of the cane." Who can say, as yet, that this crop will take its place among the special crops of our extreme Northern and Eastern States, or will occupy the place now filled by the sugar cane of the South? Nor is this important. Like all other agricultural products, the profit of sor- ghum depends on locality, soil, climate, and the commercial status of the cultivator as regards the ownership of his land; whether he pos- sesses a plantation of thousands of acres or a small farm ; whether he sets up his own sugar mill and runs a sugar plantation or depends upon a neighboring factory for his market of the 'crop from his few acres. We have a right to expect that it will find its place, as every other crop has done, and will be accepted in its proper sphere either for the do- mestic supply of molasses when convenient and economical or for con- version into sugar where circumstances are favorable. It took many years for the great cotton and woolen and iron industries to establish themselves and occupy the market, but their founders made their goods, found their market, ami pocketed their profits. They worked with perseverance, economy, and great ingenuity and skill. You can follow their example. iftiasSES&t
