Scenes and Adventures in the Semi-Alpine Region of the Ozark Mountains of Missouri and Arkansas

III. Combustibles.

36. Sulphur. In flocculent white deposits, in a spring, Jefferson county, Missouri.

37. Mineral Coal. Bituminous, slaty coal, constitutes a very large geological basin in the Ohio and Mississippi valleys, where it appears to have resulted from the burial of ancient forests. At Pittsburgh, I found it composing thick strata in elevated grounds, on the south banks of the Monongahela river. In an excursion up that stream, it characterizes its banks at intervals for forty miles. It inflames easily, burns with a pitchy smoke and bituminous smell, and throws out a great heat. It occurs in veins in limestone, along with argillaceous slate, indurated clay, red sandstone, and bituminous shale, which are arranged in alternate strata, one above the other, preserving an exact parallelism with the waters of the Alleghany, Monongahela, and Ohio rivers. The coal always constitutes a vein between the shale and clay which are found immediately above and below it. The clay appears to have originated from the decomposition of shale; for it may be observed in all stages of the decomposition, from a well-characterized argillaceous slate, to plastic clay.

The veins of coal are from a foot to nine feet in thickness, and the strata of coal, shale, limestone, &c., are repeated; so that the sides of the hills which afford coal, exhibit several strata, with the rock intervening, one above another. The greatest distance, in a perpendicular direction, from one stratum to another, is perhaps one hundred feet; and such is the regularity of the coal formation in this region, that the description of one pit, or bed, will apply almost equally to any other within a circuit of two hundred miles, every section of which is characterized by coal. Sometimes pyrites of a tin-white color are found mixed among the coal. In Missouri, it occurs at Florrisant.

38. Graphite—Plumbago. Twelve miles south of Potosi, Washington county, Mo., in a large body.

39. Sulphuret of Lead.

a. Galena. One of the most remarkable formations of this ore in America, if not in the world, is furnished by the metalliferous limestones of the Mississippi. Of these, Missouri furnishes one of the most celebrated localities. These mines were first explored by the renowned Mississippi Company, in 1719, and have continued to be worked during the successive changes which it has experienced under the French, Spanish, and Americans, to the present period. The number of mines now wrought is about fifty, and the quantity of lead annually smelted is estimated at three millions of pounds. The ore is the common galena, with a broad glittering grain, and bluish-gray color, and is found accompanied by sulphate of barytes, blende, pyrites, quartz, and calcareous spar. It yields, on assay, eighty-two per cent. of metallic lead, the remainder being chiefly sulphur. (Vide "View of the Lead-Mines.")

b. Granular Sulphuret of Lead. Mine La Motte, Madison county, Missouri.

c. Cobaltic Sulphuret of Lead. With the preceding.

40. Oxide of Lead. Earthy, yellow. Wythe county, Virginia.

41. Carbonate of Lead. Lead-mines of Missouri. It occurs in some of the mines as a crust, or thin layer, on ores of galena.

42. Sulphuret of Zinc. In the form of black blende. Lead-mines of Missouri.

43. Oxide of Zinc. Earthy, grayish-white. In the mineral called "dry-bone." Missouri lead-mines.

44. Iron.

a. Iron Glance. In the Iron Mountain and Pilot Knob, on the sources of the river St. Francis, Missouri. It occurs in vast masses, granular, and sometimes specular, without iridescence. Also, on White river, Arkansas.

b. Micaceous Oxide of Iron. Sources of the St. Francis river, Missouri. A vein of this ore, several feet wide, is found in red sienite, on the banks of the river St. Francis, at the Narrows, Madison county, Missouri Territory. Its unusual appearance has for several years attracted the attention of the inhabitants. It is situated four miles south of the extensive lead-mines of La Motte, and in the centre of a highly interesting geological and mineralogical section of country. The rocks at that place are the old red granite and sienite, in mountain masses, with veins of greenstone, greenstone porphyry, and gneiss.

c. Red Oxide of Iron. Flint river, Tennessee.

d. Brown Hæmatite. On the dividing ridge between Strawberry and Spring rivers, Arkansas.

e. Argillaceous Oxide of Iron—Ironstone. Banks of the Monongahela, Pennsylvania.

f. Sulphuret of Iron. Accompanying the ores and vein-stones of the Missouri lead-mines.

g. Magnetic Oxide of Iron. Fifteen miles below the Hot Springs, on the Washita river, Arkansas. In quantity.

45. Black Oxide of Manganese. On Big Sandy river, Kentucky. Also, on the sources of the Maramec and Spring rivers, Missouri, accompanied by the brown oxide of iron.

46. Native Copper. Scattered masses of this metal have been found on Big river, and also in a shaft sunk near Harrisonville, Illinois. Nothing, however, is known in America, to equal the vast quantities of this metal found in the trap veins on the banks of lake Superior.

47. Sulphate of Copper. On the Washita river, fifteen miles below the Hot Springs, Arkansas.

MINERAL RESOURCES OF THE WEST.

A LETTER TO CHARLES G. HAINES, ESQ., SECRETARY OF THE ASSOCIATION
FOR THE PROMOTION OF INTERNAL IMPROVEMENTS AT NEW YORK.

New York, October 5th, 1819.

Sir: In reply to your communication of the 4th inst., I submit the subjoined remarks on the following questions:—

I. "To what extent are the lead, and other mines, worked in our western country, either by the United States' government, or by individuals?"

In the extensive region to which this inquiry has allusion, are found numerous ores, salts, ochres, and other minerals; and the catalogue is daily increasing, by the discovery of new substances, which promise to become important to the commerce of the western country; but the only mines worked are those of lead, iron, and coal.

The lead-mines are situated in Missouri Territory, (formerly Upper Louisiana,) and extend on the western bank of the Mississippi for a distance of about one hundred miles, by forty in width, comprising the present counties of Washington, St. Genevieve, Jefferson, and Madison. The first lead-ore was discovered by De Lochon, La Motte, and others, acting under the authority of the Company of the West, as early as 1720. Since which period, the number of mines has been annually increasing by new discoveries, under the jurisdiction which has been successively exercised over that country by France, Spain, and the United States. The number of mines now worked is forty-five; thirty-nine of which are in Washington county, three in St. Genevieve, one in Madison, and two in Jefferson. The quantity of lead annually smelted from the crude ore, I have estimated at three million pounds; and the number of hands to whom it furnishes employment, at eleven hundred. A considerable proportion of these are, however, farmers, who only turn their attention to mining a part of the year, when their farms do not require their labor; the residue are professed smelters and miners, including blacksmiths and others, whose services are constantly required. The price of lead at the mines is now four dollars per cwt. It is worth four dollars and fifty cents on the banks of the Mississippi, at St. Genevieve and Herculaneum, and is quoted at seven dollars in Philadelphia. The ore exclusively worked is the common galena, or sulphuret of lead, with a broad glittering grain. It is found in detached pieces and beds in red clay, and in veins in limestone rock, accompanied by sulphate of barytes, calcareous spar, blende, quartz, and pyrites. It melts easily, yielding, in the large way, from sixty to seventy-five per cent. of pure metal. By chemical analysis I procured eighty-two per cent. of metallic lead from a specimen of common ore at Mine à Burton. The residue is chiefly sulphur, with a little carbonate of lime and silex. It contains no silver, or at least none which can be detected by the usual tests.

All the lead smelted at these mines is transported in carts and wagons to the banks of the Mississippi, and deposited for shipment at Herculaneum or St. Genevieve. The different mines are situated at various distances, from thirty to forty-five miles in the interior, and the cost of transportation may be averaged at seventy-five cents per cwt. In summer, when the roads are in good order, it may be procured at fifty cents; but in the spring and fall, when the roads are cut up, it will cost one dollar. The transportation from Herculaneum and St. Genevieve to New Orleans, may now be procured at seventy cents per cwt. This is less than the sum paid, previous to the introduction of steamboats on the Mississippi and its tributary streams. Hence, it costs more to convey a hundredweight of lead forty miles by land, in wagons and carts, than to transport the same one thousand miles (the distance from Herculaneum to New Orleans) by steamboats. An improvement of the streams of the mine country, so as to render them navigable at all seasons for keel-boats and barges, is therefore a subject of the first moment. The Maramec river, a stream of one hundred and eighty miles in length, and a hundred yards wide at its mouth, which enters the Mississippi eighteen miles below St. Louis, draws its waters from the mining counties of Washington, Jefferson, St. Genevieve, and the unincorporated wilderness on the south-east, and the fertile counties of Franklin and St. Louis on the north-west; and its south-eastern tributaries meander throughout the mine tract. The principal of these are Grand river and Mineral Fork, which are navigable in spring and fall for keel-boats of a small size, and might, I believe, be rendered so throughout the year, at an inconsiderable expense.

The lead-mines are exclusively worked by individuals, either under the authority of leases obtained from the United States for a limited time; on lands which were granted by the French or Spanish, and the titles to which have been subsequently confirmed by the United States; on unconfirmed lands; or in violation of existing laws.

There are few sections of the valley of the Mississippi which are not characterized by iron and coal. Iron-ore is abundant on the Ohio and its tributaries, particularly on the Alleghany, Monongahela, and Muskingum. It is worked at several foundries in the counties of Fayette, Armstrong, and Alleghany, in Pennsylvania. The most noted furnaces are at Brownsville, from which the extensive foundries at Pittsburgh are chiefly supplied with pig-iron. It is also worked at Zanesville, on the Muskingum, and on Brush creek, in Ohio; and a foundry at Cincinnati, and another at Louisville, in Kentucky, are supplied with pig-iron from the latter place. The ore is chiefly of that kind called the argillaceous oxide, and produces iron which is well adapted for steam-engine machinery, and for hollow-ware.

Stone-coal, of an excellent quality, is abundant at Pittsburgh, where it is largely consumed in iron-foundries, glass-furnaces, and other manufactories, and also in private dwellings. The most extensive pits or galleries are situated immediately opposite the city, on Coal Hill, where it has been pursued into the hill eight or nine hundred yards. It is found breaking out on the banks of the Alleghany at several places, at and near Kittaning, where beds of it have been opened; and I have even observed traces of it in the vicinity of Olean, near the head of Genesee river, in the State of New York. On the Monongahela it extends by Williamsport, Brownsville, and Greensburgh, to the vicinity of Morgantown, in Virginia; and such is the abundance of this mineral, and the uniformity and regularity which the geological structure of this part of the country presents, that there is no considerable section of it, within a circle of two hundred miles in diameter around Pittsburgh, which does not afford beds of good inflammable coal. Pursuing the Ohio down from Pittsburgh, it is successively worked at Wellsburg, Wheeling, Gallipolis, and Maysville. In Illinois, on Great Muddy river, and at Alton; in Missouri, at Florissant, and on Osage river; and in Arkansas, on the Washita river; this valuable mineral has also been found.

II. "What mines have been discovered?"

V. "Where are the most valuable mines to be found in the western country?"

The reply to these inquiries has been, in part, anticipated by the preceding details. Lead and other mines are, however, found in several other sections of the western country. An extensive body of lead-ore is found near Prairie du Chien, on the west bank of the Mississippi, about five hundred miles above St. Louis. The ore is in the state of a sulphuret, is easily reduced, and yields about sixty-two and a half per cent. of metal. These mines are worked in an imperfect manner by the savages, the Sacs and Foxes, the original owners of the soil; and considerable quantities are annually brought down to St. Louis by the north-west traders. Lead-ore is also found on the river Desmoines of the Mississippi, where it was formerly worked by the French—on the Osage, Gasconade, and Mine river of the Missouri; on the White river and its tributaries; on the St. Francis; and on the Arkansas, where it is combined with a small proportion of silver. It is also found at Cave-in-Rock, Gallatin county, Illinois, accompanied by fluor spar; at Drennon's Lick and Millersburgh, in Kentucky; and on New river, at Austinville, in Wythe county, Virginia. At the latter place, it has been worked without interruption for nearly fifty years; and the mines still continue to be wrought. The ore is galena, accompanied by the carbonate of lead, and the earthy oxide of lead; the latter of which is worked in the large way, as is said, to a profit.

Zinc is found in Washington county, Missouri, in considerable quantities; but only in the state of a sulphuret.

Copper has been found in small masses, in a metallic state, on Great Muddy river, and at Harrisonville, Monroe county, Illinois. A grant of land made to P. F. Renault, in 1723, at Old Peoria, on the Illinois river, specifies the existence of a copper-mine upon it; but the most remarkable bodies of copper which the globe affords, are stated to exist on the western shores of Lake Superior, and on the Upper Mississippi. It is found in the metallic state, but accompanied also, as is said, by the sulphuret and carbonate of copper. The ores stretch over a very extensive region, and have been traced as low as the falls of St. Anthony. There is, indeed, reason to believe that copper is disseminated from the west bank of Great Muddy river, in Illinois, in a north-west direction, to the western shore of lake Superior, as all the streams, so far as observed, which flow either north or south at right angles with such a line, afford traces of copper. Thus, the Kaskaskia, the Illinois and its tributaries, the St. Peter, Wisconsin, and the southern forks of the Wabash and Miami, all furnish specimens of copper, as well as lead, zinc, and iron. An attempt was made by President Adams to explore the copper-mines of the north-west; but I know not what success attended the undertaking. Considering the certainty with which all travellers, since the days of Carver, have spoken of the existence of these mines, with the daily concurrent testimony of traders from that quarter, and their great importance in a national point of view, it is matter of surprise that they have been so long neglected. Is not the present an auspicious time for authorizing a mission into that quarter, for the purpose of exploring its physical geography?

Iron is a mineral common to all parts of the western country. One of its most remarkable localities is the head of the river St. Francis, in Missouri Territory, where it extends through a considerable part of Madison and Washington counties. The most noted body is called the Iron Mountain, and is situated about forty miles west of the Mississippi, in Bellevieu, Washington county. The ore is here found in immense masses, and forms the southern extremity of a lofty ridge of hills, which consists chiefly of red granite, but terminates, in a rich alluvial plain, in a mass of solid ore. It is chiefly the micaceous oxide, accompanied by the red oxide, and by iron-glance. It melts very easily, producing a soft, malleable iron.

Coal is not less common, and may be considered among those extensive mineral formations which stretch, in so remarkable a manner, throughout the vast basin included between the Alleghany and Rocky mountains. Salt and gypsum may also be referred to the same great geological formations, as they are to be traced, accompanying each other, from the western section of New York, to the southern banks of the Arkansas, where immense quantities of salt and gypsum exist. Clay, flint, ochre of various kinds, saltpetre, alum, reddle, soapstone, plumbago, oil-stone, marble, serpentine, &c., may be enumerated among the useful minerals of less importance, which characterize that region.

III. "To what extent and advantage do you think the mines might be worked, under proper management and superintendence?"

IV. "Are the laws of Congress, which have been passed in relation to our lead-mines, salutary in their operation?"

I have stated the amount of lead annually produced by the Missouri mines at three millions of pounds, which, on reflection, I think is sufficiently high. But there are numerous difficulties opposed to the successful progress of mining in that country, by the removal of which, the amount would be greatly augmented. Some of these difficulties arise from the peculiar nature of the business, from a want of skill, or of mining capital in those by whom mining operations are conducted; but by far the greatest obstacle results from the want of a systematic organization of the mining interest by the United States, or from defects in existing laws on the subject.

Immediately after the occupation of Louisiana by the United States, inquiry was made into the situation and extent of the mines; and a law was passed, reserving all mines discovered on the public lands, and authorizing the territorial executive for the time being to lease out such mines for a period of three years. A radical defect in this law appears always to have been, that there was not, at the same time, authorized the appointment of a specific agent for the general management and superintendence of mines. Such an officer has long been called for, not less by the public interest, than by the intelligent inhabitants of the western country, who feel how nearly a proper development of its mineral wealth is connected with their individual prosperity and national independence. The superintendent should reside in the mine country, and such a salary should be attached to the office as to induce a man of science to accept it. His duty should be to report annually to Congress the state of the mines, their produce, new discoveries, and proposed alterations in existing laws. He should lease out and receive rents for the public mines—prevent the destruction of timber on mineral lands, and the working of mines without authority, and should be charged with the investigation of the physical and geographical mineralogy of the country. At present, the most flagrant violations of the laws are practised—mines are worked without leases—wood is destroyed on lands which are only valuable for the wood and the lead-ore they contain; and the government derives but a small revenue from those celebrated mines, which, whether we consider their vast extent, the richness of the ore, or the quantity of metal they are capable of annually producing, are unparalleled by any other mineral district in the world.

There is another feature in the existing law, which is not beneficial in its operation. It is that clause restricting the terms of leases to three years. To embark in mining operations with profit, it is necessary to sink shafts and galleries, build engines, and erect other necessary works, which are, in some degree, permanent in their nature, and require much time and expense in their completion. A considerable part of the period must, therefore, elapse before the mine can be put in a state for working; and no sooner is that done, and it begins to afford a profit, and promises a reward for the expense incurred, than the expiration of the lease throws all these works into the hands of some new adventurer, or more successful applicant. This prevents many from engaging in mining on the public lands, and especially those who would be best able to prosecute the business; and of the number who take leases, a great proportion continue to pursue the desultory method of mining in alluvial[20] ground, introduced at an early period by the French, but which is attended with very great uncertainty.

Improvements remain also to be introduced in regard to the processes of mining, the furnaces employed, and the method of raising the ore. Inseparable from this subject is the distribution of more enlarged practical and scientific views of mining and minerals generally, which might, in a great degree, be effected by the dissemination of practical treatises on the subject, or by the employment of experienced and skilful miners from Europe.

When such improvements shall be effected, with others to which it is not necessary here to advert—when miners are properly secured in the object of their pursuit, either by permanent purchases from government, or by leases for a long period of years—and when the facilities for transportation which that country is destined to afford, by the improved navigation of its streams, and by the introduction of turnpikes, roads, and bridges, are introduced, there is reason to conclude that the annual amount of lead produced will far surpass the proceeds of those mines under the present arrangement, and, indeed, it is impossible to calculate the extent to which it may be carried. It is, perhaps, a moderate estimate to say, that they are capable of being made to yield, by judicious management, six millions of pounds of lead per annum, and that they will furnish employment to three thousand hands.

During my late tour throughout the western country, including nearly a year's residence in the interior of Missouri, I devoted much time to this interesting subject, and have been enabled to collect a body of facts on the physical resources and character of that country, and particularly of its mines and minerals, which it is my design to lay before the public. I must, therefore, refer you to this work, which is now in press, for further details on this subject, and, in the mean time, I beg your indulgent perusal of this hasty outline.

With respect, Sir,
Your obedient servant,
Henry R. Schoolcraft.
