In this estimate are included all persons concerned in the operations of mining, and who draw their support from it; wood-cutters, teamsters, and blacksmiths, as well as those engaged in digging and smelting lead-ore, &c. The estimate is supposed to embrace a period of three years, ending 1st June, 1819, and making an average product of 3,726,666 lbs. per annum, which is so near the result arrived at in the preceding details, as to induce a conclusion that it is essentially correct, and that the mines of Missouri, taken collectively, yield this amount of pig-lead annually.
The United States acquired possession of the mines in the year 1803,fifteen years ago last December; and, assuming the fact that they have annually produced this quantity, there has been smelted, under the American government, fifty-five million pounds of lead.
On the view which has now been taken of the Missouri mines, it may be proper here to remark—
1. That the ores of these mines are of the richest and purest kind, and that they exist in such bodies as not only to supply all lead for domestic consumption, but also, if the purposes of trade require it, are capable of supplying large quantities for exportation.
2. That although at different periods the amount of lead manufactured has been considerable, yet this produce has been subject to perpetual variation, and, upon the whole, has fallen, in the aggregate, far short of the amount the mines are capable of producing. To make these mines produce the greatest possible quantity of lead of which they are capable, with the least possible expense, is a consideration of the first political consequence, to which end it is desirable that the reserved mines be disposed of, to individuals, or that the term for which leases are granted be extended from three to fifteen years, which will induce capitalists, who are now deterred by the illiberality of governmental terms, to embark in mining. That there be laid a governmental duty of two and a half cents per pound on all imported pig and bar lead, which will exclude foreign lead from our markets, and afford a desired relief to the domestic manufacturer. The present duty is one cent per pound. But this does not prevent a foreign competition; and the smelters call for, and appear to be entitled to, further protection.
3. That although the processes of mining now pursued are superior to what they were under the Spanish government, yet there is a very manifest want of skill, system, and economy, in the raising of ores, and the smelting of lead. The furnaces in use are liable to several objections. They are defective in the plan, they are constructed of improper materials, and the workmanship is of the rudest kind. Hence, not near the quantity of metallic lead is extracted from the ore which it is capable, without an increase of expense, of yielding. There is a great waste created by smelting ore in the common log furnace, in which a considerable part of the lead is volatilized, forming the sublimated matter which adheres in such bodies to the sides of the log furnaces, and is thrown by as useless. This can be prevented by an improvement in its construction. To pursue mining with profit, it is necessary to pursue it with economy; and true economy is, to build the best of furnaces, with the best of materials. At present the furnaces are constructed of common limestone, which soon burns into quicklime, and the work requires rebuilding from the foundation. Not only so, but the frequency with which they requireto be renewed, begets a carelessness in those who build them, and the work is accordingly put up in the most ordinary and unworkmanlike manner. Instead of limestone, the furnaces ought to be constructed of good refractory sandstone, or apyrous clay, in the form of bricks, which will resist the action of heat for a great length of time. Both these substances are the production of that country, and specimens of them are now in my possession.
4. From the information afforded, it has been seen that the mines are situated in a country which affords a considerable proportion of the richest farming-lands, producing corn, rye, wheat, tobacco, hemp, flax, oats, &c., in the greatest abundance, and that no country is better adapted for raising cattle, horses, hogs, and sheep. The country is well watered, and with the purest of water; the climate is mild and pleasant, the air dry and serene, and the region is healthy in an unusual degree. Every facility is also afforded by its streams for erecting works for the manufacture of white and red lead, massicot, litharge, shot, sheet-lead, mineral yellow, and the other manufactures dependent upon lead. The country also abounds with various useful minerals besides lead, which are calculated to increase its wealth and importance. It is particularly abundant in iron, zinc, manganese, sulphur, salt, coal, chalk, and ochre.
5. That a systematic organization of the mining interest would have a tendency to promote the public welfare. To this end, there should be appointed an officer for the inspection and superintendence of mines. He should reside in the mine country, and report annually to the proper governmental department on the state of the mines, improvements, &c. His duty should consist in part of the following items, viz.:
a.To lease out public mines, and receive and account for rents.
b.To prevent the waste and destruction of wood on the public lands.
c.To see that no mines were wrought without authority.
d.To keep the government informed, periodically, of the quantity of lead made at the different mines, and of new discoveries of lead, or any other useful minerals; and,
e.To explore, practically, the mineralogy of the country, in order fully to develop its mineral character and importance. Connected with these duties, should be the collection of mineralogical specimens for a national cabinet of natural history at Washington.
The superintendent of mines should be a practical mineralogist, and such a salary attached to the office as to induce a man of respectable talents and scientific acquirements to accept the appointment. To allow the manufacturers of lead every advantage consistent with the public interest, the rent charged on mines should not exceed two and a half per cent. on the quantity manufactured, which is equivalent to the proposed governmental duty on imported lead, whereby the revenue wouldnot only be kept up, but might be considerably enhanced. The foregoing details exhibit an annual produce of 3,726,666 pounds of lead, which, it is presumable, may be half the quantity the mines are capable of producing, with proper management. But, estimating the lead at four cents per pound, and taking that as the average quantity, the annual rents, at two and a half per cent., will create a revenue of thirty-two thousand four hundred and ninety dollars.
This subject is believed to be one that commends itself to the attention of the government, which has, from a policy early introduced, reserved the mineral lands on the public domain. No one can view it in the light of these facts, without perceiving the propriety and necessity of an efficient organization of this branch of the public interest.
[12]The following sketch of the life of Burton is given by Colonel Thomas H. Benton, of St. Louis, in the Enquirer of that city, October 16, 1818:—"He is a Frenchman, from the north of France. In the fore-part of the last century, he served in the Low Countries, under the orders of Marshal Saxe. He was at Fontenoy when the Duke of Cumberland was beat there by that Marshal. He was at the siege of Bergen-op-Zoom, and assisted in the assault of that place when it was assailed by a division of Marshal Saxe's army, under the command of Count Lowendahl. He has also seen service upon this continent. He was at the building of fort Chartres, on the American bottom; afterwards went to fort Du Quesne (now Pittsburgh), and was present at Braddock's defeat. From the life of a soldier, Burton passed to that of a hunter; and in this character, about half a century ago, while pursuing a bear to the west of the Mississippi, he discovered the rich lead-mines which have borne his name ever since. His present age cannot be ascertained. He was certainly anold soldierat fort Chartres, when some of the people of the present day were little children at that place. The most moderate computation will make him a hundred and six. He now lives in the family of Mr. Micheaux, at the little rock ferry, three miles above St. Genevieve, and walks to that village almost every Sunday to attend mass. He is what we call a square-built man, of five feet eight inches high, full chest and forehead; his sense of seeing and hearing somewhat impaired, but free from disease, and apparently able to hold out against time for many years to come."

[16]On this passage, Mr. Silliman remarks, "that sulphur is not poisonous to men or animals.... Thecarbonateof barytes is eminently poisonous; but we have never heard that the sulphate is so. May not the licking around the furnaces expose the cattle to receive lead, in some of its forms, minutely divided? or, if it be not active in the metallic state, both the oxide and the carbonate, which must of course exist around the furnaces, would be highly active and poisonous. Is it not possible, also, that some of the natural waters of the country may, in consequence of saline or acid impregnations, dissolve some of the lead, and thus obtain saturnine qualities? We must allow, however, that we are not acquainted with the existence of any natural water thus impregnated."—Jour. Sci., Vol. III.

A CATALOGUE OF THE MINERALS OF THE MISSISSIPPI VALLEY.
In the arrangement of this catalogue, the order introduced in Professor Cleveland's mineralogical tables, has been chiefly observed. It is the commencement of an investigation into the physical history, character, and mineral resources of the West, which it will become the duty of future observers to continue and perfect. The field is an extensive one, and invites attention. The order and beauty that are observed in this branch of natural history, afford as striking proofs as any of the other departments of it, of that design which, in so remarkable a manner, pervades the organization of the various classes of bodies, animate and inanimate, on the surface of the globe. So far as respects mineralogy, its species and varieties have not all been seen, in crystallized forms, agreeably to our imperfect state of microscopical knowledge; but as far as the species have been brought within observation, in the classes of crystals and crystallized ores, they rival, in their colors and exact geometrical forms, other systems of bodies.
In revising the list, those specimens are dropped, respecting which further reflection or examination has shown, either that the early descriptions were imperfect, or that the quantity of the mineral was deficient.

First Class.
1.Nitre—Saltpetre.This salt, in its efflorescent state, exists extensively in the limestone caves of Missouri and Arkansas. It also impregnates the masses of earth found in these recesses. This earth is lixiviated with wood-ashes, which allows the nitre to take a crystalline form. I visited a large cavern, about eighty miles south-west of Potosi, where this salt was manufactured, and observed its efflorescences in other caves in the Ozark range.
2.Muriate of Soda.About one hundred and fifty thousand bushels of common salt are annually made from the United States' saline on Salt river, in Illinois. It appears, from the remains of antique broken vessels found in that locality, to have been manufactured there by the ancient inhabitants. There is a saline, which has been profitably worked, on Saline creek, in St. Genevieve county. Two salt springs are worked, in a small way, in Jefferson county, Mo. The springs in Arkansas are reported to be extensive, and rumors of rock-salt on its plains have been rife, since the purchase of Louisiana. The hunters whom I met in the Ozark range, invariably affirmed its existence, in crystalline solid masses, in that quarter; from which also, it is to be recollected, De Soto's scouts brought it, in 1542.
3.Sulphate of Barytes—Heavy Spar.This mineral is found, in considerable quantities, at the principal lead-mines of Missouri, west of the Mississippi. It presents its usual characters—it is heavy, white, shining, opaque, and easily fractured. It is sometimes found crested, columnar, prismatic, or in tabular crystallizations. Its surface is frequently covered by a yellowish, ochrey earth, or ferruginous oxide. It sometimes exists as the matrix of the sulphuret of lead—more frequently, as one of its accompanying minerals.
4.Carbonate of Lime.
a.Calc. Spar.This form of the carbonate of lime is common in the lead-mine regions of Missouri. At Hazel run, it constitutes, to some extent, the gangue of the lead-ores. It is generally imbedded in lumps in the red clay mineral soil. These lumps are round, externally; but, on being broken, reveal a rhomboidal structure, and are beautifully transparent.
b.Stalactites.This form of the carbonate of lime is found in a cave on the head-waters of Currents river, in Missouri. The stalactites are found in concretions resembling icicles hanging from the roof, or incolumns reaching to the floor. The specimens are translucent. Stalactites are also found in a very large cave (Winoca) on Findley's fork, one of the tributaries of White river, Arkansas. They form two large vases in this cave, which are filled with the most crystalline water.
c.Stalagmite(Calcareous Alabaster). The cave which has just been mentioned on Findley's fork, affords this mineral in small, solid globules, which strew the floor of the cave.
5.Fluor Spar.The elevated lands on the west banks of the Ohio, near the picturesque shores of Cave-in-Rock, in Illinois, disclose this mineral. It exhibits its well-known character. It is generally of a purple, or amethystine hue, and crystallized, as its primary form, in cubes. Externally, these crystals are dull. Its association here is with the ores of lead, which have been extensively searched for in former times. It is plentifully found, sometimes in large crystals, which have an external appearance as if they had been subjected to the influence of turbid water. It has been thus far, chiefly, explored in the diluvial stratum.
6.Gypsum.Foliated masses of this mineral occur in the river cliffs in St. Clair county, Illinois. It is found in large quantities near the salines in Upper Arkansas. Dr. Sibley, speaking of the formation in that vicinity, says: "It is a tract of about seventy-five miles square, in which nature has arranged a variety of the most strange and whimsical vagaries. It is an assemblage of beautiful meadows, verdant ridges, and rude misshapen piles of red clay, thrown together in the utmost apparent confusion, yet affording the most pleasing harmonies, and presenting in every direction an endless variety of curious and interesting objects. After winding along for a few miles on the high ridges, you suddenly descend an almost perpendicular declivity of rocks and clay, into a series of level and fertile meadows, watered by some beautiful rivulets, and adorned here and there with shrubby cotton trees, elms, and cedars. These meadows are divided by chains formed of red clay, and huge masses of gypsum, with here and there a pyramid of gravel. One might imagine himself surrounded by the ruins of some ancient city, and that the plain had sunk by some convulsion of nature more than one hundred feet below its former level; for some of the huge columns of red clay rise to the height of two hundred feet perpendicular, capped with rocks of gypsum, which the hand of time is ever crumbling off, and strewing in beautiful transparent flakes, along the declivities of the hill, glittering like so many mirrors in the sun."
7.Sulphate of Magnesia.A large and curious cavern has been discovered in the calcareous rocks at Corydon, near the seat of government of Indiana, which is found to yield very beautiful white crystals of this mineral. To what extent these appearances exist, is unknown; but the cavern invites exploration.
8.Alum.Efflorescences of the sulphate of alumina exist in a calcareous cavern in the elevated ranges of Bellevieu, in the county of Washington, Mo. No practical use is made of it.
9.Quartz.This important family of mineral bodies exists, in many of its forms, on the west banks of the Mississippi. They will be noticed under their appropriate names.
a.Granular Quartz.There is a very large body of this mineral about eight miles west of St. Genevieve, near the Potosi road. It is known as the site of a remarkable cave. The sides, roof, and floor of the cave, consist of the most pure and white granular quartz. It is quite friable between the fingers, and falls into a singularly transparent and beautiful sand. Each of these grains, when examined by the microscope, is found to be a transparent molecule of pure quartz. It possesses no definable tint of color, is not acted upon by either nitric or muriatic acids, and appears to be an aggregation of minute crystals of quartz. It occurs in several caves near the road, whose sides are entirely composed of it; and its snowy hue, and granular structure, give it the appearance of refined sugar. It appears to me to be composed of silex nearly or quite pure, and possesses, as I find on treatment with potash, the property of easy fusibility. Could the necessary alkali and apyrous clays be conveniently had at this spot, I cannot conceive a more advantageous place for a manufactory of crystal glass.
b.Radiated Quartz.This mineral is found in great abundance at the Missouri lead-mines, where it bears the striking name of mineral blossom, or blossom of lead—an opinion being entertained that it indicates the presence or contiguity of lead-ore. Examined with care, it is found to consist of small crystals of quartz, disposed in radii, which resemble the petals of a flower. These crystals are superimposed on a basis consisting of thin lines, or tabular layers, of agate. It is found either strewn on the surface of the soil, imbedded in it, or existing in cavities in the limestone rock.
c.Chalcedony.This species is brought down the Mississippi or Missouri, and deposited in small fragments along the Missouri shore. It also constitutes the principal layers in the thin tabular, or mamillary masses, which constitute the basis of the radiated quartz. Most commonly, it is bluish-white, or milk-white.
d.Agatized Wood.Fragments of this mineral are brought down the Missouri, and deposited, in occasional pieces, along the banks of the Mississippi.
e.Hornstone—Chert.This substance appears to have been imbedded extensively in the calcareous strata of the Mississippi valley; for it is scattered, as an ingredient, in its diluvions. Frequently it is in chips, or fragments, all of which indicate a smooth conchoidal fracture. Sometimes it consists of parts of nodules. Sometimes it is still solidly imbedded inthe rock, or consolidated strata, as on the coast below Cape Girardeau, Mo. Indeed, so far as observation goes, it characterizes all the district of country between the western banks of the Mississippi river, and the great prairies and sand deserts at the foot of the Rocky mountains. Its color is generally brown, with different shades of yellow, black, blue, or red. It appears nearly allied to flint, into which it is sometimes seen passing. It runs also into varieties of jasper, chalcedony, and common quartz; and the different gradations from well-characterized hornstone, until its distinctive characters are lost in other sub-species of quartz, may be distinctly marked. The barbs for Indian arrows, frequently found in this region, appear to have been chiefly made of hornstone.
f.Jasper.This mineral also appears to have been imbedded in the silico-calcareous rocks of the western valley; and it is found, in the fragmentary form, on the banks of the Mississippi, and also on its plains below the Rocky mountains. The fine yellow egg-shaped pebbles of White river, are common jasper. Several specimens, picked up in a desultory journey, possess striking beauty. The first is a uniform bottle-green, very hard, and susceptible of a high polish. The second is the fragment of a nodular mass, consisting of alternate concentric stripes of green, brown, and yellow; the colors passing by imperceptible shades into each other. A specimen found in Potosi consists of alternate stripes of rose and flesh red.
g.Agate.This mineral is picked up, in a fragmentary form, along the banks of the Mississippi. Its original repository appears to have been the volcanic and amygdaloidal rocks about its sources, which have been extensively broken down by geological mutations, during ante-historical periods. The fragments are often beautifully transparent, sometimes zoned or striped. Sometimes they are arranged in angles, presenting the fortification-agate. The colors are various shades of white and red, the latter being layers of carnelian. All the pieces found in this dispersed state are harder than the imbedded species, and are with difficulty cut by the lapidary.
h.Opal.A single specimen of this mineral, from the right banks of the Ohio, near Cave-in-Rock, Illinois, is of a delicate bluish-white, and opalesces on being held to the light. It is not acted on by acids. This locality is remarkable as yielding galena, heavy spar, blende, calcareous spar, fluor spar, pyrites, coal, and salt. It belongs to the great secondary limestone formation of the Ohio valley. It is cavernous, and yields some fossil impressions.
i.Red Ferruginous Quartz.This occurs as one of the imbedded materials of the diluvion of the Mississippi valley.
k.Rock Crystal.Very perfect and beautiful crystals of this mineral are procured near the Hot Springs of Arkansas. They consist, generally, of six-sided prisms, terminated by six-sided pyramids. Some of theseare so perfectly limpid, that writing can be read, without the slightest obscurity, through the parallel faces of the crystals.
l.Pseudomorphous Chalcedony.Lake Pepin, Upper Mississippi. This appears to have been formed by deposition on cubical crystals, which have disappeared.
m.Tabular Quartz.West bank of the Mississippi, Missouri. Of a white color, semi-transparent. The plates are single, and the lines perfectly parallel.
n.Hoary Quartz.West banks of the Mississippi, Mo. The character of hoariness appears to be imparted by very minute crystals, or concretions of quartz, on the surface of radiated quartz.
o.Common Quartz.This mineral is found in veins of from one to eight or ten feet wide, in the argillaceous rock formation in the vicinity of the Hot Springs of Washita. It is also seen, in very large detached masses, on the south bank of White river. The character of these rocks will not be recognized on a superficial view; for they have a gray, time-worn appearance, and are so much covered by moss, that it was not until I had broken off a fragment with a hammer, that I discovered them to be white quartz. Pebbles of quartz, either white or variously colored by iron, are common on the shores of White river, and, joined to the purity and transparency of the waters, add greatly to the pleasure of a voyage on that beautiful stream.
p.Buhrstone.Raccoon creek, Indiana. This bed is noted throughout the western country, and affords a profitable branch of manufacture. It covers an area of from ten to fifteen acres square. Its texture is vesicular, yet it is sufficiently compact to admit of being quarried with advantage, and the stones are applied to the purposes of milling with the best success.
q.Sedimentary Quartz—Schoolcraftite.This mineral occurs three miles from the Hot Springs of Washita. It is of a grayish-white color, partaking a little of green, yellow, or red; translucent in an uncommon degree, with an uneven and moderately glimmering fracture, and susceptible of being scratched with a knife. Oil stones for the purpose of honing knives, razors, or tools, are occasionally procured from this place, and considerable quantities have been lately taken to New Orleans. It gives a fine edge, and is considered equal to the Turkish oil-stone. It appears to me, from external character and preliminary tests, to consist almost entirely of silex, with a little oxide of iron. Its compactness, superior softness, specific gravity, and coloring matter, distinguish it from silicious sinter. It has been improperly termed, heretofore, "novaculite." It contains no alumine. It sometimes reveals partial conditions, or spots, of a degree of hardness nearly equal to common quartz.
r.Carnelian.Banks of the Mississippi, above the junction of the Ohio. Traces of this mineral begin to be found, as soon as the heavy alluvial lands are passed. It is among the finest detritus of the mineralsof the quartz family, brought down from upper plains. The fragments, in these lower positions, are small, transparent, and hard, colored red or yellowish.
s.Basanite—Touchstone.This mineral is found in the Mississippi detritus; but no fixed locality has been ascertained.
10.Pumice.The light, vesicular substance, found floating down the Missouri and Mississippi, is not, properly speaking, a true pumice, capable of the applications of that article in the arts; but it cannot be classified with any other species. It is more properly a pseudo-pumice, arising from partial volcanic action on the formations of some of the tributaries of the Missouri, which originate in the Rocky mountains. It is brought down by the June flood, sometimes in large masses, which, as the waters abate, are left on the islands or shores. It is incompletely vitrified, consisting of spongy globules. The masses are irregularly colored, agreeably to the vitrified materials, red, black or brown. Its tenacity is very great.
30.Mica.In the granitical, or primitive district, at the sources of the St. Francis. The great body of these rocks is a sienite, or sienitic granite, or greenstone. Like the northern granitical tracts, the mica is generally replaced by hornblende. The folia, usually, are small.
31.Feldspar.With the preceding. The great bulk of these granitical formations consists of red feldspar. Where the greenstone becomes porphyritic, the feldspar is a light green.
32.Hornblende.With the preceding. This mineral assumes its crystalline form, in large areas of the sienite rock. With the two preceding minerals, mica and feldspar, and common quartz, it constitutes the mountain peaks of that remarkable district. It is the only locality, except the Washita hills, where these formations rise to an elevation above the great metalliferous sandstone, and carbonaceous deposits of the central area of the Mississippi valley, south of the Sauk rapids, above St. Anthony's falls, and the head-waters of the St. Peter's, or Minnesota river. The latter constitute the northern limits of the great horizontal, sedimentary, semi-crystallized rocks west of the Alleghanies.
33.Greenstone Porphyry.With the preceding.
34.Puddingstone.In the tongue of land formed by the junction of the Ohio with the Mississippi, directly beneath the alluvial lands at the old site of fort Massac, and at the village called "America." Also, in large, broken blocks, along the west shores of the Mississippi, near the "chalk banks," so called, in Cape Girardeau county, and at Cape Garlic, on the west banks of the Mississippi.
33.Native Alumine—White, friable, pure Clay.At the head of Tiawapeta bottom, Little Chain of Rocks, west banks of the Mississippi, Cape Girardeau county, Missouri. This remarkable body of white earth is locally denominated chalk, and was thus called in the first edition of this catalogue. It is employed as a substitute for chalk, but is found to contain no carbonic acid, and is destitute of a particle of calcia. It appears, from Mr. Jessup,[18]to be nearly pure alumine. The traveller, on ascending the Mississippi from the mouth of the Ohio, passes through a country of alluvial formation, a distance of thirty-five miles. Here the first high land presents itself on the west bank of the river, in a moderately elevated ridge, running from south-east to north-west, and terminating abruptly in the bank of the river, which here runs nearly at right angles with the ridge, and has been worn away by the action of the water. This ridge consists of secondary limestone, overlying a coarse reddish sandstone, which, at the lowest stage of the water in summer, is seen in huge misshapen fragments, at the immediate edge of the water, and at intervals nearly half way across the river, as well as on the Illinois shore. The mineral occurs in mass, abundantly. It is nearly dry, of a perfectly white color, and chalky friability. It embraces masses of hornstone, resembling flint. It also occurs at a higher point on the same shore, two miles below the Grand Tower.
34.Plastic White Clay.Gray's mine, Jefferson county, Mo.
35.Opwagunite[19]—Geognostic Red Clay.Prairie des Couteau, between the sources of the St. Peter's river and the Missouri. It exists in lamellar masses, beneath secondary masses. It is of a dull red color, is soft, compact, easily cut, and is a material much employed and valued by the Indians for carving pipes, and sometimes neck ornaments. Occasionally it has brighter spots of pale red. It is also found on the Red Cedar, or Folle Avoine branch of Chippewa river, Wisconsin, of a darker color, approaching to that of chocolate. It is polished by the Indians with rushes.
