Chapter XXXVI: Introduction: OF THE PALÆONTOLOGICAL ROCKS.--After passing some fifty (2)

3. _Variegated Clay._--On the banks of the River St. Peter's, Upper Mississippi. Neither the quantity in which it exists, nor the precise locality is known. Its color is white, variegated with stripes, spots, or clouds of red or yellow.

4. _Azure Blue Clay of St. Peter's._--The locality of this substance, as communicated by the Indians, is the declivity of a hill, in the rear of the village of Sessitongs, one mile above the confluence of the Terre Blue River with the St. Peter's. It is found near the foot of this hill, between two layers of sandstone rock, in a vein about fifteen inches in thickness. This vein is elevated about twenty feet above the waters of the Terre Bleu, and does not extend far in the direction of the river. Having been resorted to by the Sioux Indians a long time, a considerable excavation has been made, but the supply is constant. The color of this mineral substance (its distinguishing character) is an azure copper blue of more or less intensity. It is ductile and moderately adhesive, when first taken up, or when moistened with water, but acquires an almost stony solidity on drying. It is considerably adulterated with sand or particles of quartz. It parts with its moisture rapidly on exposure to the atmosphere, and dries without much apparent diminution of volume.

5. _Green Clay of St. Peter's._--This differs little from the preceding, except in its color, which is a deep or verdigris green, admitting some diversity of shades. Its composition appears to be, essentially, alumina, silica, carbonate of copper, water, and iron.

6. _Opwagunite_; _Calamet Stone_; _Pipe Stone._--The last of these terms is a translation of the first, which is Algonquin. Under these names, a peculiar kind of stone, which is much employed by the Indians for pipes, has been alluded to by travellers and geographers from the earliest times. It appears to be a variety of argillaceous wacke. Its color is most commonly a uniform dull red, resembling that of red chalk. Sometimes it is spotted with brown or yellow, but these spots are very minute, and the colors usually faint. It is perfectly opaque, very compact in its structure, and possessing that degree of hardness which admits its being cut or scraped with a knife, or sawed without injury to a common hand-saw, when first raised from the quarry; but it acquires hardness by exposure, and even takes a polish. But it is not capable of receiving a polish by the usual process of rubbing with grit-stone and pumice, these substances being too harsh for it. The Indian process is to scrape or file it smooth, and give it a polish by rubbing with the scouring rush. Its powder is a light red, and emits an argillaceous odor when wetted. This substance is procured at the Coteau des Prairie, intermediate between the sources of the St. Peter's and the Great Sioux Rivers. Some other places have been mentioned as affording this mineral, particularly a locality on the waters of Chippewa River; but the mineral procured here is chocolate-colored.

e. _Magnesian Minerals._

1. SERPENTINE.

At Presque Isle Point, Lake Superior, common and precious, in isolated masses; also, in connection with, and imbedding native copper, along the southern shore of Lake Superior, at Ontonagon River, &c.

2. STEATITE.

At Presque Isle, near River au Mort, Lake Superior, in connection with the serpentine formation. Also, at the Lake of the Woods, of a black or very dark color, where it is employed by the Indians in carving pipes.

3. ASBESTOS.

_Common Asbestos._--In serpentine and steatite, at Presque Isle Point, Lake Superior. Also, in minute veins, in detached masses of diallage and serpentine rocks, on the west shore of Lake Michigan. These veins are no more than a fourth of an inch in width; and the fibres of asbestos occur transversely. They are very flexible, and easily reducible into a flocculent mass.

f. _Barytic Minerals._

SULPHATE OF BARYTES.

_Lamellar Sulphate of Barytes._--In detached masses, imbedded in diluvial soil, at the mines of Peosta, or Dubuque, on the Upper Mississippi, where it is accompanied by sulphuret of lead, calcareous spar, &c. Also, at the Mine au Fevre (now Galena), and at the mouth of the Sissinaway River, on the east banks of the Mississippi, between Prairie du Chien and Fort Armstrong. Its colors are white or yellow, and it is frequently incrusted with a thin coat of yellow oxide of iron. It is most commonly opaque. The only translucent specimen seen was procured at Dubuque's mines.

g. _Strontian Minerals._

SULPHATE OF STRONTIAN.

_Foliated Sulphate of Strontian._--At Presque Isle (Wayne's Battle Ground), on the Maumee River, Wood County, Ohio. It occurs in veins and cavities, in compact limestone, most commonly in the form of flattened prisms. Its color is blue, frequently a very light or sky-blue, and the crystals are fully translucent, or even transparent. In some instances, they appear to have suffered a partial decomposition, and fall into fragments in the act of raising, or are covered with a white powdery crust, frequently visible only on the summits or terminating points of the prisms. The same limestone yields crystallized calcareous spar. Both these substances are abundant in the rocky banks and in the bed of the Maumee. Also, on Grosse Isle, Detroit River, Michigan.

h. _Bituminous Minerals._

1. BITUMEN.

_Petroleum._--Occurs in cavities, in loose fragments of limestone rock, along the west shore of Lake Michigan, between Milwaukie and Chicago. These masses of rock lie promiscuously among fragments of quartz, granite, sandstone, fossil madrepores, &c., along the alluvial shore of the lake, and appear to have been washed up from its bed. The petroleum is in a free and liquid state; but, where it has suffered an exposure to the atmosphere, it has acquired a stiff and tar-like consistence passing into _maltha_. Not unfrequently, fragments of mineral coal are also found scattered along these shores, and there is reason to conclude that a bituminous formation exists in the contiguous inferior strata forming the basin of the lake.

2. GRAPHITE.

_Granular Graphite._--In a small vein, in the clay-slate of the River St. Louis, at the head of the nine-mile portage. It is coarse-grained and _gritty_.

3. COAL.

_Slaty Coal._--The only spot where this mineral has been observed, in situ, is at La Charbonniére, on the west banks of the Illinois River, at the computed distance of one hundred and twenty miles south of the post of Chicago. It is here seen in horizontal strata, not exceeding two or three inches in thickness, interposed between layers of sandstone and shale. Breaking out on the declivity of the bank of the river, where the overlaying strata are constantly crumbling down, and thus obscuring the seams, no very satisfactory examination could be made in a hasty visit; but the nature and position of the rock strata and soils, and the general aspect of the country, do not justify the conclusion that the bed is of much thickness or extent. Valuable beds may be discovered, however, by exploring this formation. This coal has a shining black color, a slaty structure, inflames readily, burning with a bright flame. It is very fragile where exposed to the weather, falling into fine fragments. Hence, a very black color has been communicated to the contiguous and overlaying soil, which is manifestly more or less the result of disintegrated coal.

Detached fragments of coal, corresponding in mineral characters with the above, are occasionally found around the southern shores of Lake Michigan. The inference, as to the existence of coal around the shores of this lake, is obvious. And we are led to inquire: Does the La Charbonniére formation of coal exist in the sandstone and limestone strata forming the table-land between the Illinois River and Lake Michigan, and reappearing around the basin of the latter, but at such a depression below its surface as to elude observation? And, if so, does not this coal formation extend quite across the southern portion of the peninsula of Michigan? The secondary character of the region alluded to, so far as observed, the horizontal and relative position of the strata, and the general uniformity which is generally observed in the species and order of the coal measures, favor this suggestion.

i. _Soda._

1. MURIATE OF SODA.

No traces of salt are known to have been discovered in those parts of the territory of the United States situated north of latitude 46° 31´ (which is that of the Sault Ste. Marie) and _east_ of the Mississippi River. The great secondary formations which pervade the western country cease south of this general limit, and with them terminate the salt springs, the gypsum beds, the coal measures, and other connected minerals which are generally found in association. It is one of the most important facts which the science of geology has contributed to the stock of useful information, that, in the natural order of the rocky and earthy deposits, muriate of soda always occupies a position contiguous to that of gypsum. This intimate connection between the sulphate of lime and the muriate of soda, enables us, by the discovery of the one, to predict, with considerable but not unerring certainty, the presence of the other. It adds weight to an observation first made among the salt formations of Europe, to find its general correctness corroborated by the relative position of these substances in the United States. These remarks will apply particularly to the salt formations of New York, and to some portions of the muriatiferous region of Virginia and the Arkansas.

There appears to be a salt formation extending from the northwest angle of the Ohio through Michigan, for a distance of two hundred to three hundred miles. It commences in the Seweekly country, passing around the Sandusky River of Lake Erie, where an extensive bed of granular gypsum has recently been discovered, and continues, probably, northwest, so as to embrace the Saganaw basin, and reach quite to the end of the peninsula, and embracing, perhaps, the Gypsum Islands of Lake Huron, ten miles northeast of Michilimackinac. All the brine springs and gypsum beds noticed in the region are situated in the line of this formation.

During the fall of 1821, a number of gentlemen at the Island of Michilimackinac united in the expenses of a tour for exploring the Skeboigon River, a stream which originates in the peninsula of Michigan, and flows into Lake Huron opposite the Island of Bois Blanc. The particular object of this party was to ascertain the precise locality of certain salt springs reported to exist upon that stream. They proceeded to the places indicated, and examined several springs more or less impregnated with salt, but reported that, owing to the jealousy and hostility of those bands of Indians who were found upon that stream, they were not enabled fully to accomplish the object in view.

There are several salt springs reported to exist near the Indian village of Wendagon, on the Sciawassa River, and others on the Titabawassa River, the principal tributaries of the Sagana. Little is, however, known respecting these springs, but the water is represented to be so strongly impregnated, that the Indians manufacture from it all the salt necessary for their villages.

Grand River Valley has also been mentioned among the localities of salt water and gypsum rocks.

Hints may thus be derived of value to the future commerce of the country. Scarcely any of the new states are without indications of the existence of salt. Every day is adding to the number of localities.

In the region _west_ of the Mississippi, I was informed that salt occurs, in the crystallized form, in the territories of the Yanktons, who inhabit the flat country at the sources of the River St. Peter's. In certain parts of these plains, the salt exists on the surface. It is mixed with earth, in specimens brought to me, but crystallized in cubes, very imperfect, of a gray or grayish-white color. The Indians scrape it up from certain parts of the prairies or plains, where the salt water is prevented from draining off.

2. ALKALINE SULPHATE OF ALUMINA.

This salt exists, in the form of efflorescences, in the cavities and fissures of rocks along the southeast parts of the shores of Sagana Bay, Lake Huron, and in the argillaceous formations at Erie, on Lake Erie, Pennsylvania.

* * * * *

These positions embrace the principal localities of minerals noticed. In travelling rapidly through a remote wilderness, there was but little opportunity to explore off the track; and the whole observation was confined to the mere surface of the country, which is much obscured by diluvial and alluvial formations.

It will be seen that the region of Lake Superior has been a fruitful field for mineralogical inquiry, and it is one which invites further exploration. Its mineralogy affords a variety of interesting substances which are objects of scientific research, and it may be anticipated to be the future theatre of extensive mining operations. The country northwest of Lake Superior, and the Upper Mississippi north of the Falls of St. Anthony--consisting mostly of upheaved primitive rocks and the pebble-drift, or diluvial, formations--has furnished but few subjects of mineralogical remark.

The district of country between the Falls of St. Anthony and Prairie du Chien, in common with the more southern portions of the Mississippi Valley, partakes of all the interest which the mineral kingdom presents in a calcareous and metalliferous country of secondary formation. It has added considerably to my collection. It is probable the Rivers St. Peter's, St. Croix, and Chippeway would well reward exploration; but the mines of Dubuque particularly invite a mineralogical survey. Their future importance cannot fail to be duly appreciated.

If the country has put on an aspect unfavorable to mineralogy, its geological features have been observed to sustain its interest.

Much of the interest growing out of the examination, for the first time, of the mineralogy and natural history of the country, is such as to commend itself, in an especial manner, to the consideration of men of science, and of associations devoted to scientific details, rather than the department of a government. To these former, nature is a storehouse of facts, and a perpetual anxiety is felt by this class of observers to know the range, not only of our rock formations, but of our plants, shells, fossils, and other classes of objects in our physical geography. Such desires I have endeavored, as far as my means permitted, to gratify. The fresh-water conchology of the lakes and rivers visited was often attractive, when other objects excited little interest. The species collected in this department have been referred to the New York Lyceum of Natural History.

With these remarks, the result of an arduous and interesting journey through a part of the continent hitherto unexplored, I have the honor to conclude my report, and to terminate the trust confided to me.

I am, sir, with respect,
Your obedient servant,

DEPARTMENT OF WAR, 3d December, 1822.

The Secretary of War, to whom was referred the resolution of the
Senate of the 8th May last, requesting the President of the United
States "to communicate to the Senate, at the commencement of the next
session of Congress, any information which may be in the possession
of the Government, derived from special agents or otherwise, showing
the number, value, and position of the copper mines on the south

department.

All which is respectfully submitted.

J. C. CALHOUN.

To the PRESIDENT OF THE UNITED STATES.

SAULT STE. MARIE, October 1, 1822.

SIR: In reply to the inquiries, contained in a resolution of the Senate of the United States, respecting the existence of copper mines in the region of Lake Superior, inclosed to me in a note from the War Department, dated 8th May, 1822, I have the honor to submit to you the following facts and remarks:--

1. In relation to "_the number, value, and position of the copper mines on the south shore of Lake Superior_." The remote position of the country alluded to, the infrequency of communication, and the little reliance to be placed on information derived through the medium of the aborigines or of traders, who are wholly engrossed with other objects, presents an embarrassment at the threshold of this inquiry, which must be felt by every person who turns his attention to the subject. The information sought for demands a minute acquaintance with the natural features and mineral structure of the country, which can only be acquired by personal examination; and it is a species of research requiring more leisure, better opportunities, and a freer participation in personal fatigue, than usually falls to the share of tourists and travellers. Not only are those difficulties to be encountered which are inseparable from the collection of isolated facts in a new and unsettled country, but those, also, which are peculiar to the subject, connected as it is, at every stage of the inquiry, with the prejudices and superstitions of the Indian tribes. [B.] It can, therefore, excite little surprise that, after having been the theme of speculation for more than a century, and obtained the notice of several works of merit in Europe,[236] both the position and value of these mineral beds have continued to the present times to be but partially known. To ascertain more clearly their value and importance to the Republic were objects more particularly confided to me as a member of the expedition sent by the Indian Department, in the year 1820, to traverse and explore those regions. My report of the 6th of November of that year--a copy of which, marked A, is herewith transmitted--gives the result of that inquiry. After a lapse of two years, little can be added. Reflection and subsequent inquiry convince me that the facts advanced in that report will be corroborated by future observation. No circumstance has transpired which is calculated to prove that my suggestions with regard to the fertility and future importance of those mines are fallacious; on the contrary, all information tends to strengthen and confirm those suggestions. Specimens of pure and malleable copper continue to be brought in to me by the aborigines from that region, but it is not deemed necessary to particularize in this place the additional localities. It will be sufficient to observe, that the number of these new discoveries justifies the expectations that have been created respecting the metalliferous character of the region of the Ontonagon, and the south shore of Lake Superior. [C.]

[236] _Vide_ Jameson's Mineralogy, Parkes's Chemical Catechism,
Phillips's Elementary Introduction to Mineralogy.

I shall here add the result of an accurate analysis made upon a specimen of this copper at the mint of Utrecht, in the Netherlands, at the request of Mr. Eustis, minister plenipotentiary from the United States, who carried samples of the American copper to that country. The report of the inspector of the mint, which communicates the result of this analysis, has the following remarks upon the natural properties of this species of copper, and the mode of its production: "From every appearance, the piece of copper seems to have been taken from a mass that has undergone fusion. The melting was, however, not an operation of art, but a natural effect caused by a volcanic eruption. The stream of lava probably carried along in its course the aforesaid body of copper, that had formed into one collection, as fast as it was heated enough to run, from all parts of the mine. The united mass was probably borne in this manner to the place where it now rests in the soil. The crystallized form, observable everywhere on the original surface of the metal that has been left untouched or undisturbed, leads me to presume that the fusion it has sustained was by a process of nature; since this crystallized surface can only be supposed to have been produced by a slow and gradual cooling, whereby the copper assumed regular figures as its heat passed into other substances, and the metal itself lay exposed to the air.

"As to the properties of the copper itself, it may be observed that its color is a clear red; that it is peculiarly qualified for rolling and forging; and that its excellence is indicated by its resemblance to the copper usually employed by the English for plating. The dealers in copper call this sort _Peruvian copper_ to distinguish it from that of _Sweden_, which is much less malleable. The specimen under consideration is incomparably better than Swedish copper, as well on account of its brilliant color as for the fineness of its pores and its extreme ductility. Notwithstanding, before it is used in manufactures, or for the coining of money, it ought to be melted anew, for the purpose of purifying it from such earthy particles as it may contain. The examination of the North American copper, in the sample received from his excellency the minister, by the operation of the cupel and test by fire, has proved that it does not contain the smallest particle of silver, gold, or any other metal." It is a coincidence worthy of remark, that the suggestions offered by the assayer respecting the volcanic origin of these masses of copper, are justified by the leading features of the Porcupine Mountains, and by the melted granites found upon the heights called Grande Sables and Ishpotonga.

2. The second and third inquiries of the resolution relate to "_the names of the Indian tribes who claim the mines, and the practicability of extinguishing their title_." By the treaty concluded at this post on the 16th of June, 1820, the Ojibwai[237] Indians cede to the United States four miles square of territory, bounded by the River St. Mary's, and including the portage around the falls.[238] This is the most northerly point to which the Indian title has been extinguished in the United States. The different bands of Ojibwais possess all the country northwest of this post, extending through Lake Superior to the sources of the Mississippi, where they are bounded by the Assennaboins, the Crees, and the Chippewyans of the Hudson Bay colony. Their lands extend down the Mississippi to the Sioux boundary, an unsettled line between the junction of the River De Corbeau and the Falls of St. Anthony. South of Lake Superior, they claim to the possessions of the Winnebagoes, on the Ouisconsin and Fox Rivers, and to those of the Pottawatamies and Ottoways, on Lake Michigan. The Wild Rice, or Monomonee Indians, are an integral part of the Ojibwai nation, deriving their name from the great reliance they place on the zizania aquatica as an article of food. They live in small, dispersed bands between the Ojibwais of the lake, and the Winnebagoes of Fox River. Those residing among the Ojibwais speak the same language, but with many peculiarities and corruptions on the waters of Green Bay. They claim the respective tracts upon which they are located. These are, principally, the valleys of the Fox and Monomonee Rivers, and the rice lands contiguous to the Fol. Avoine, Clam Lake, and Lac de Flambeau, which lie on the table-lands between Lake Superior and the Mississippi.

[237] For the different names applied to this tribe of Indians, see
Appendix H.

[238] _Vide_ acts passed at the second session of the 16th Congress
of the United States, page 88.

The right of soil to all that part of the Peninsula of Michigan not purchased by the United States is divided between the Ojibwais and the Ottoways. The former claim all the shores and islands of Lake Huron situated north of the Saganaw purchase, except those in the vicinity of Michilimackinac and the St. Martin, or Gypsum Islands, which were ceded by treaty on the 6th of July, 1820.[239] Their territories continue north, through the River St. Mary's, embracing the country on both banks, and the islands in the river, saving Drummond's Island, which is garrisoned by the British, and the Four Mile concession at the Sault or Falls, now occupied by a detachment of the United States' army. It is not deemed necessary to point out the limits of their territories with more precision, or to pursue them into the Canadas, where they are also very extensive. It will sufficiently appear, from this outline, that the discoveries of copper on the south shore of Lake Superior are upon their lands. That some of these discoveries have been made upon, or will be traced to, the possessions of the North Monomonees, is also probable.

[239] _Vide_ acts passed at the second session of the 16th Congress,
p. 91.

With respect to the practicability of extinguishing the Indian title, no difficulty is to be apprehended. Living in small villages, or tribes of the same mark, scattered over an immense territory, and often reduced to great poverty by the failure of game and fish, it is presumed there would be a disposition among their chiefs and head men to dispose of portions of it. Those districts which most abound in minerals, presenting a rough and rocky surface, are the least valuable to them as hunting-grounds; and the goods and annuities which they would receive in exchange must be vastly more important to them than any game which these mineral lands now afford.

3. "_The probable advantage which may result to the Republic from the acquisition and working of these mines._" How far metallic mines, situated upon the public domain, may be considered as a source of national wealth, and what system of management is best calculated to produce the greatest advantages to the public revenue, are inquiries which are not conceived to be presented for consideration in this place; nor should I presume to offer any speculations upon topics which have been so often discussed, and so fully settled. In applying axioms, however, to a species of productive industry, the results of which are so very various under various situations, great caution is undoubtedly necessary; and it must appear manifest, on the slightest reflection, how much the comparative value of metallic mines, equally fertile and productive, ever depends upon situation and local advantages. Dismissing, therefore, all questions of abstract policy, I shall here adduce a few facts in relation to the fertility of these mineral beds, and their position with respect to a market--points upon which their value to the nation must ultimately turn.

That copper is abundantly found on the south shore of Lake Superior has been shown. It is unnecessary here to add to, or repeat the instances of its occurrence, or to urge, from an inspection of the surface, the fertility of subterranean beds. All the facts which I possess in relation to this subject are before you, and you will assign to them such importance as they merit. It is a subject upon which I have bestowed some reflection and much inquiry, superadded to limited opportunities of personal observation, and the result has led me to form a favorable estimate of their value and importance. It is not only certain that a prodigious number of masses of metallic copper are found along the borders of the lake, but every appearance authorizes a conclusion that they are only the indications of near and continuous veins. Some of these masses are of unexampled size, and all present metallic copper in a state of great purity and fineness. Of its ductile and excellent qualities for the purposes of coinage and sheathing, the analysis of Utrecht leaves no doubt. It is true that a mistaken idea has prevailed among travellers and geographers respecting the weight of the great mass of copper on the Ontonagon River; but it is, nevertheless, of extraordinary dimensions, and I have endeavored to show, from their works, how these errors have originated, and that the metal is disseminated throughout a much greater extent of country, and in masses of every possible form and size. Until my facts and data can, therefore, be proved to be fallacious, I must be permitted to consider these mines not only fertile in native copper and its congenerous species, but unparalleled in extent, and to recommend them as such to the notice of the Government.

But, whatever degree of incertitude may exist respecting the riches of these mines, their situation with respect to a market can admit of no dispute. As little can there be concerning the advantages which this situation presents for the purposes of mining and commerce. Let us compare it with that of other mines, and appeal to acknowledged facts for the decision. The value of a coal mine, a stone quarry, or a gypsum bed, often arises as much from its situation as its fertility. But the proposition may be reversed with respect to a metallic mine, the value of which to the proprietor arises more from its fertility and less from its situation. Gold, silver, copper, tin, lead, &c., when separated from the matrix of the mine, are so valuable that they can bear to be transported a long journey over land, and the most distant voyage by water. Their worth in coined money, produce, or manufactures, is not fixed in the particular circles of country where they are dug up, but depends upon the seaboard market, and embraces all countries. The silver of Mexico and Peru circulates throughout Europe, and is carried to China. It is no objection to those mines that they are situated in the Cordilleras, or upon the high table-lands of the American continent, and must be carried a thousand miles upon the backs of mules to the seaside. The very discovery of those mines has rendered many poor silver mines of Europe of no value, although possibly situated in the environs of the best silver markets in the world. It is the fertility, and not the situation of such mines, that constitutes their chief value; and it is so with many of the coarser metals.

The tin of the Island of Banka, and the Peninsula of Siam in Asia, and the copper of Japan, find their way to Europe, and are articles of commerce in the United States. The cobalt of Saxony is sent to Pekin, and the platina of Choco, to all parts of the world. In all these instances, the fertility of the mines compensates for every disadvantage of situation. But this principle is not alone confined to mines of tin, copper, &c.; it even holds true of the heavy and bulky articles of iron, lead, and salt. The lead of Missouri finds a market at New York, Philadelphia, and Boston, and will be carried to Europe. It is no objection that it must be conveyed in wagons forty miles from the interior, and sent a voyage of 3,000 miles in steamboats and merchant ships. The great fertility of the mines counterbalances the disadvantages of its remote position from the market, and it is the price of the metal in the market which always regulates its price at the mines. The malleable iron of Sweden is consumed on the summits of the Alleghany, although its strata are replete with iron ore, which is worked at numerous forges along the rivers which proceed from each side of it. It is believed that the salt springs of Onondaga, from their copiousness alone, would supply a vast portion of the interior and seaboard of the United States with salt, even if the facilities of water carriage had not been presented by the Erie Canal. The value of such mines and minerals ever depends as much upon the abundance as upon the favorable position of them. It is far otherwise with quarries of stone, gypsum, marl, fossil coal, &c., whose contiguity to a good market establishes their value. No abundance of these articles would justify a land carriage of one hundred miles. They constitute a species of mining, the profits and value of which increases in the ratio of the surrounding population, and as the country advances in improvements. But this advantage is far less sensibly felt, and cannot be considered essential to the successful working of mines of silver, copper, &c. Neither the remote position, therefore, of the Lake Superior copper mines, nor the want of a surrounding population, present objections of that force which would at first seem to exist; and it is confidently believed that, if their fertility is such as facts indicate, they may be opened and wrought with eminent advantage to the Republic. But let us examine their situation with respect to a market, and compare it with that of other mines of the same metal, and of some of the coarser metals, which bear a considerable land, and the most distant water carriage. To favor the inquiry, let it be granted for the moment that proximity of situation to a market, or free water carriage, are indispensable to the success and value of the most fertile mines.

Assuming the confluence of the Ontonagon River with Lake Superior (which is apparently the centre of the mine district) as the place where the metal is first to be embarked for market, it must be carried down the lake 300 miles to the Sault or rapids of St. Mary's. Here, if it is in barges, it may descend the rapids in perfect safety, as is the invariable practice of the traders on arriving with their annual returns of furs and skins from the north. If in vessels, it must be transferred either into boats or carts, and carried half a mile to the foot of the rapids, where it will again be embarked in vessels, and transported through the Lakes Huron, St. Clair, and Erie, and their connecting straits, to Buffalo, a distance of 650 miles. The progress made in the construction of the great canal which is to connect the lakes and Atlantic, is such as to leave no doubt upon any reasonable mind of the full completion of that work with the close of the year 1824. Through this channel, the transportation is to be continued in boats or barges, by a voyage of 353 miles, to the Hudson at Albany; thence a sloop navigation of 144 miles, which, for speed and freedom from risk, is perhaps unequalled in all America, takes it into the harbor of New York, making the entire distance, from the mouth of the Ontonagon, 1,447 miles. From New York it is distributed to our naval depots, and to the markets of Europe. It is exchanged for the lead of Missouri, the iron of Sweden, or the silver of Mexico; and the same ready communication transports the return cargo to Buffalo, from whence the commerce is extended, by means of the lakes, throughout western New York, Pennsylvania, Ohio, Indiana, Illinois, Michigan, and the interminable regions of the north. Thus it is seen that, when the Erie Canal is completed, a free and direct water communication, from the mines to one of the best markets in America, will exist, in which the rapids of St. Mary's are the only interruption, and this is only an interruption to large vessels. Not only so, but the Ontonagon River may be ascended many miles with vessels of light burden, and thus the copper of Lake Superior, wafted from the heart of the interior, and from the base of the Porcupine Mountains, into the harbors of New York, Philadelphia, &c. Of this whole distance, 1,047 miles are now navigated by the largest class of river craft and lake schooners; the balance of the distance is the length of the Erie Canal. (See Note D.)

Let it be recollected that there are no mines of copper situated upon the margin of the sea, and that every quintal of sheet copper, bolts, nails, &c., which we receive from Great Britain, Russia, Sweden, or Japan, is transported a greater or less distance on turnpikes or canals, before it reaches the place of shipment. The richest copper mines of the Russian empire are seated on the summits of the Uralian Mountains; those of Fahlun, in Sweden, and Cornwall, in England, are scarcely more favored as to position; and, owing to a want of coal, all the ores raised at the latter are transported into Wales to be smelted.[240] But we need not resort to Europe for instances. All the lead raised at the fertile mines in Missouri is transported an average distance of forty miles in carts and wagons before it reaches the banks of the Mississippi. Steamboats take it to New Orleans, a distance, by the shortest computation, of 1,000 miles. But it must still pass through the Gulf of Mexico, and encounter the perils of the Capes of Florida, and a voyage of 2,000 miles along the coast of the United States, before it reaches its principal marts. The average cost of transporting a hundredweight of lead from Mine au Breton and Potosi to the banks of the Mississippi, during the year 1818, was seventy-five cents. The distance is thirty-six miles. The price of conveying the same quantity from the storehouses at Herculaneum and St. Genevieve to New Orleans, by steamboats, was seventy cents. The distance exceeds 1,000 miles. Hence, it costs more to transport a given quantity thirty-six miles by land than to convey it 1,000 by water. These rates have probably varied since, but the proportionate expense of land carriage, compared to that of water, will remain the same. A quintal of copper may, therefore, be transported from the mines of Superior to Buffalo or Lockport, in New York, for the same sum required to convey an equal quantity of lead from Potosi to St. Genevieve. If we consider the city of New York as the market of both, no hesitancy or doubt can be experienced as to the decided and palpable advantages possessed by the northern mines. It is only necessary to adduce these facts; the conclusions are inevitable. In every point of view, the distance of these mines from the market presents no solid objection to their being explored with profit to the nation.

Pig copper, which is the least valuable form in which this metal is carried to market, is now quoted in the Atlantic cities at 19 cents per pound; sheathing, at 27; brazier's, at 32. I have no data at hand to show the amount of these articles consumed in the United States, and for which we are annually transmitting immense sums to enrich foreign States. But those who best appreciate the advantages of commerce will readily supply the estimate. It would be an interesting inquiry to ascertain how much of the sums yearly paid for sheathing copper, bolts, nails, engravers' plates, &c., is contributed to the wealth of the respective foreign States who possess mines of this metal. We can look back to a period in the history of Great Britain, when that power did not contribute one pound of copper to the commerce of Europe. During a period of nine years, closing with the memorable year (in American history) of 1775, the produce of the copper mines of Cornwall was 2,650 tons of fine copper. (See Note E.) Since that time, the yearly returns of those mines exhibit a constant increase; and the copper mines of Great Britain are now the most valuable in the world. The amount produced by the mines of Cornwall and Devon, after deducting the charges of smelting, for the single year of 1810, was 969,376 pounds sterling. (See Note F.) The clear profits of the Dolgoath mine, one of the richest in Cornwall, for a period of five months, during the year 1805, was £18,000, which is at the rate of £43,200, or $192,000, per annum. Next to Great Britain, the most considerable mines of Europe are those of Russia, Austria, Sweden, and Westphalia, as it was in 1808. Of less importance are those of Denmark, France, Saxony, Prussia, and Spain. The proportion in which the British mines exceed those of the most favored European nation is as 200,000 x 67,000. (See Note G.)

There is another consideration connected with this subject which is worthy of remark. Should it be inquired what would be the effects of the purchase of these mines upon the condition of the Indian tribes, the reply is obvious. It would have the most beneficial tendency. They would not only profit by an exchange of their waste lands for goods, implements of husbandry, the stipulated services of blacksmiths, teachers, &c., but the intercourse would have a happy tendency to allay those bitter feelings which, through the instigation of the British authorities in the Canadas, they have manifested, and still continue to feel, in degree, towards the United States. The measures which the President has recently directed to be pursued to assuage these feelings of hostility, and to induce them to cherish proper sentiments of friendship and respect, are already in a train of execution that bids fair for success. Continued exertions, and the necessary and proper means, are all that seem necessary to confirm and complete the effect; and whatever measures have a tendency to increase the intercourse of American citizens with these "remote tribes," and to give them a true conception of the power and justice, and the pacific and benevolent policy of our Government, must favor and hasten such a result.

_Notes._

(B.)

Among the numerous superstitions which the Indian tribes entertain, that respecting mines is not the least remarkable. They are firmly impressed with a belief that any information communicated to the whites, disclosing the position of mines or metallic treasures situated upon their grounds, is displeasing to their manitos, and even to the Great Spirit himself, from whom they profess to derive every good and valuable gift; and that this offence never fails to be visited upon them in the loss of property, in the want of success in their customary pursuits or pastimes, in untimely death, or some other singular disaster or untoward event. This opinion, although certainly not a strange one to be cherished by a barbarous people, is, nevertheless, believed to have had its origin in the transactions of an era which is not only very well defined, but must ever remain conspicuous in the history of the discovery and settlement of America. It is very well known that the precious metals were the principal objects which led the Spanish invaders to penetrate into the interior of Mexico and Peru, and ultimately to devastate and conquer the country, to plunder and destroy its temples, and to tax and enslave its ill-fated inhabitants. It is equally certain that, to escape these scenes of cruelty and oppression, many tribes and fragments of tribes, when further resistance became hopeless, fled towards the north, preferring the enjoyment of liberty and tranquillity upon the chilly borders of the northern lakes, to the pains of servitude in the mild and delightful valleys of Mexico, and the golden plains of the Incas. In this way, many tribes who originally migrated from the north, along the Pacific Ocean, to the Gulf of California, and thence over all New Spain, were returned towards the north over the plains of Texas and the valley of the Mississippi; those tribes nearest the scenes of the greatest atrocities always pressing upon the remoter and less civilized, who, in turn, pressed upon the nations less enlightened than themselves, and finally drove them into the unfrequented forests of the north. Among these terrified tribes, the traditions of the Ojibwais affirm that their ancestors came, and that they originally dwelt in a country destitute of snows. Many tribes who now speak idioms of their language were left upon the way, and have since taken distinctive names. Among these, are the Pottawatamies, the Ottoways, &c. The latter formerly were, as they still remain, the agriculturists. The Miamis and Shawnees, whose languages bear some affinity, preceded them in their flight. The Winnebagoes, speaking a separate and original tongue, came later, and preserve more distinct traditions of their migration. All these tribes carried with them the strong prejudices and fixed hatred excited by the cruelty, rapacity, and cupidity of their European conquerors; and, above all, of that insatiable thirst for gold and silver which led the Spaniards to sack their towns, burn their temples, and torture their people. Cruelty and injustice of so glaring a character must have made upon their minds too deep an impression ever to be forgotten, or completely erased from their traditions. To that memorable epoch we must, therefore, look for the origin of that cautious and distrustful disposition which these tribes have since manifested with regard to the mines and minerals situated upon their lands; and the circumstance seems to offer an abundant excuse, if not a justification, for those prevarications and evasions which present a continual series of embarrassment to every person who seeks through their aid to develop the mineral resources, or describe the natural productions, of their territories. Hence, too, the cause why they are prone to imagine that all mineral or metallic substances obtained or sought upon their lands, are susceptible of being converted or _transmuted_ into the precious metals.

(C.)

The following _additional_ localities of native copper, derived from sources entitled to respect, and accompanied, in some instances, by specimens of the metal, may here be given:--

1. Grand Menou, or Isle Royal, Lake Superior. Captain----, of the schooner----, in the employ of the Hudson's Bay Company, on Lake Superior, describes this island as affording frequent masses of copper. While becalmed off its shores in the spring of 1822, and, afterwards, in coasting along the island for a distance of one hundred miles, his men frequently went ashore, and never failed to bring back with them lumps of metallic copper, which they found promiscuously scattered among the fragments of rock. These were more abundant in approaching its southwestern extremity, where they unite in representing it to exist in a solid vein. Specimens of limpid quartz, chalcedony, and striped agate, were also brought to me from this island. [J. S. J. J.]

2. On the extremity of the great peninsula, called by the natives Meenaiewong, or Keweena Point, which forms so prominent a feature in the physiognomy of Lake Superior. It occurs in the detached form. [J. H. J. J.]

3. At Point aux Beignes, which is the east cape of the entrance into L'Ance Quewiwenon. A mass from this place was raised from the sandstone rock, which predominates there. [J. Y. B.]

4. At Caug Wudjieu, or the Porcupine Mountains, Lake Superior; in masses, enveloped with a green crust, along the banks of the Carp, or Neemaibee River, which originates in these mountains. [W. M. G. Y. J. J.]

5. On the banks of Lac Courterroile. This lake lies near the source of the River Broule, or Cawesacotai, which enters Lake Superior near La Pointe. It occurs in the alluvial soil, which is a kind of loamy earth, with pebbles intermixed, but of a rich quality, and timbered with beech and maple. It is found mostly in small, flat masses, more or less oxidated. [B. G. J. G. Y.]

6. In a vein on the shore of Lake Superior, between La Riviere de Mort and St. John's, a little to the west of Presque Isle. [J. J.]

7. On the northeast branch of the Ontonagon River. [J. H.]

8. In the precipitous bluffs called Le Portail, and the Pictured Rocks. A green matter oozes from the seams in these rocks, and forms a kind of stalactites, which is apparently a carbonate of copper. [G. Y.]

These localities embrace a range of more than two hundred miles along the south shore of Lake Superior, which proves how intimately this metal and its ores are identified with the rocks and the soil of that region.

(D.)

In all our calculations respecting the position and advantages of these mines, too much stress cannot be laid upon the facilities of the lake navigation. It is believed that a ton of merchandise, or a barrel bulk, can be transported through the lakes at the same rates that are paid in the coasting trade of the United States. Nor is the risk greater. The best data which I can command, induce me to conclude that a quintal of copper can be conveyed from the place of shipment on Lake Superior, to the city of New York, for _one dollar_. The present price of transportation, for a barrel bulk, from Buffalo to Mackina, may be stated, on the average of freights, at 8_s._, New York. The mean weight of a barrel bulk, taking flour as the standard, may be safely put down at 200 lbs. gross, being 50 cents per cwt. But it must be recollected that there is no return freight; and, consequently, that this sum covers the expenses not only of the outward and return voyage, but still leaves a profit to the owner. Messrs. Gray and Griswold, sutlers of the 2d regiment, paid 9_s._ 6_d._, New York, per barrel bulk, from Buffalo to the Sault. This gives a result of 59 cents per cwt. But, if a return cargo could be obtained, one-half of this sum would afford an equal profit on the voyage; and it is believed that the article of bar copper could at all times be conveyed from the Sault to Buffalo for 20 cents per cwt. Being a very convenient species of ballast, it would oftentimes be taken in lieu of stone, and, consequently, cost no greater sum than the price of carrying it on board. But the facilities and cheapness of the lake navigation cannot, perhaps, be better illustrated than by stating the price of provisions at the post of St. Mary's, every article of which is carried from 300 to 700 miles through the lakes. The following statement of the assistant commissary has been politely furnished at my request:--

SAULT STE. MARIE, October, 1822.

DEAR SIR: Agreeably to your request, I send you a statement of the actual cost of subsistence stores furnished at this post for the use of troops at present making the military establishment, ordered by the Government to this place.

The prices of the several articles below enumerated are at a small advance on the stores of the settlers outside of the cantonment.

The expenses of subsisting, or rather of maintaining, a garrison at this place will be as small, if not less, per annum, than at any other frontier post in our country. The provisions for the soldier cost as little, I believe, as at any other post, and next year we shall be able to raise all the forage for the use of our beef cattle, and the horses and oxen of the quartermaster's department.

I am, dear sir, yours, &c.,
W. BICKER,
