To the Editors of the National Intelligencer.

Ashville, North Carolina, October, 1848.

Gentlemen: As you have recently been publishing a series of letters in relation to that portion of the Alleghany range which is situated in North Carolina, you may, perhaps, find matter of interest in the subject of this communication. My purpose in making it is not only to present to the consideration of those learned or curious in geology facts singular and interesting in themselves, but also, by means of your widely disseminated paper, to stimulate an inquiry as to whether similar phenomena have been observed in any other parts of the Alleghany range.

A number of persons had stated to me that at different periods, within the recollection of persons now living, a portion of a certain mountain in Haywood county had been violently agitated and broken to pieces. The first of these shocks remembered by any person whom I have seen, occurred just prior to the last war with England, in the year 1811 or 1812. Since then some half a dozen or more have been noticed. The latest occurred something more than three years ago, on a clear summer morning. These shocks have usually occurred, or at least been more frequently observed, in calm weather. They have generally been heard distinctly by persons in the town of Waynesville, some twenty miles off. The sound is described as resembling the rumbling of distant thunder, but no shaking of the earth is felt at that distance. In the immediate vicinity of the mountain, and for four or five miles around, this sound is accompanied by a slight trembling of the earth, which continues as long as the sound lasts —that is, for one or two minutes. After each of these shocks the mountain was found to be freshly rent and broken in various places.

Having an opportunity afforded me a few days since, I paid a visit to the locality, and devoted a few hours to a hurried examination. It is situated in the northeastern section of Haywood county, near the head of Fine's creek. The bed of the little creek at the mountain is probably elevated some twenty-six or seven hundred feet above the level of the ocean. The valley of the French Broad, at the Warm Springs, some fifteen miles distant, is twelve hundred feet lower. They are separated, however, by a mountain ridge of more than four thousand feet elevation above the sea, and there are high mountains in all directions around the locality in question. The immediate object of interest is the western termination of a mountain ridge nearly half a mile to the east of the house of Mr. Matthew Rogers. The top of this ridge, at the place where it has been recently convulsed, is some three or four hundred feet above the creek, at its western extremity, but it rises rapidly for some distance as it goes off to the eastward towards the higher mountain range. The northern side of this ridge I had not time to examine, but the marks of violence are observable at the top of the ridge, and extend in a direction nearly due south, down the side of the mountain four or five hundred yards, to a little branch; thence across it, over a flat or gentle slope, and up the side of the next ridge as far as I went, being for three or four hundred yards. The tract of ground examined by me was perhaps half a mile in length from north to south. The breadth of the surface subjected to violence was nowhere

The sides of the mountain generally are covered by a good vegetable mould, not particularly rocky, and sustaining trees of large size. But along the belt of convulsion the rocks are much more abundant, and there are only young trees growing, the elasticity of which enabled them to stand during the shocks.

With reference to the mineral structure of the locality, it may be remarked that that entire section seems to constitute a hypogene formation. It consists of granites, gneiss, sometimes porphyritic, hornblende rock, micaceous schists, clay-slate, and various other metamorphic strata. The nearest aqueous rocks that I know of are the conglomerate sandstone and sedimentary limestone, in the vicinity of the Warm Springs, fifteen miles distant in a direct line. If any volcanic rock has been found in hundreds of miles I am not aware of it. The mountain itself bears the most indubitable marks of plutonic origin. It consists mainly of a grayish white granite, in which the felspar greatly predominates, but it is sometimes rendered dark by an excess of mica in minute black scales. This latter mineral I saw also there in small rather irregular crystals. Some portions of the rock contained, however, its three ingredients, in nearly equal proportions; the quartz, in color, frequently approaching ash gray. In several places I observed that the granite was cut vertically by veins of gray translucent quartz, of from one to six inches in thickness. There were also lying in places on the ground lumps of common opaque white quartz, intersected by narrow veins, not exceeding half an inch in thickness, of specular iron, of the highest degree of brilliancy and hardness that that mineral is capable of possessing. It may be remarked that there are, in different directions within two miles of the locality, two considerable deposits of magnetic iron ore. The only rock which I observed there possessing any appearance of stratification seems to consist of mica, hornblende and a little felspar, in a state of intimate mixture. Having but a few hours to remain there, I do not pretend that there are not many other minerals at the locality; but I have no doubt but that the predominating character of the formation is such as I have endeavored to describe it, and I have been thus minute, in order that others may be able to judge more accurately in relation to the cause of the disturbances.

Before visiting the locality I supposed that the phenomena might be produced by the giving way of some part of the base of the mountain, so as to produce a sinking or sliding of the parts; but a moment's examination was decisive on this point. It not unfrequently happens that aqueous

rocks rest on beds of clay, gravel, &c., which may be removed from underneath them by the action of running water or other causes. Cavities are thus produced, and it sometimes happens that considerable bodies of secondary limestone and other sedimentary strata sink down with a violent shock. This, however, is found to be true only of such strata as are deposited from water. But at the locality under consideration the rocks are exclusively of igneous origin, and, I may add, two of the class termed hypogene or "netherformed." For though felspar and hornblende have been found in the lower parts of some of the lavas, where the mass had been subjected to great pressure and cooled slowly, yet quartz and mica have never been found as constituents of any volcanic rock, not even in the basaltic dikes and injected traps, where there must have been a pressure equal to several hundred atmospheres. It is universally conceded by geologists that those rocks of which these minerals constitute a principal part, have been produced at great depths in the earth, where they were subjected to enormous pressure during their slow cooling and crystallization. Prior, therefore, to the denudation which has exposed these masses of granite to our view, they must have been overlaid and pressed down while in a fluid state by superincumbent strata of great thickness and vast weight. It is not probable, therefore, that any cavities could exist, nor, even if it were possible that such could be the case, is it at all likely that a granite arch which once upheld such an immense weight would in our day give way under the simple pressure of the atmosphere; or, even if we were to adopt the improbable supposition that the mass of granite compos­ing this mountain had been formed at a great depth below the present sur­face of the earth, and forced up bodily by plutonic action, there is as little reason to believe that any cavities could exist. In fact, they are never found under granites. On looking at the surface of the ground at this place there is no appearance to indicate any general sinking of the mass. At the top of the ridge, where the fractures are observable across it, there is no variation in the slope of the surface or depression of the broken parts. Immediately below it, where the mountain has great steepness, equal at least to an inclination of forty-five degrees, where the line of fracture is parallel to the direction of the ridge, the surface is sunk suddenly ten or fifteen feet. This state of things, however, would inevitably be produced at such an inclination by the force of gravity alone, causing the parts sep­arated by the shock to sink somewhat as they descend the mountain side. Lower down, where the steepness is not so great, the elevations much ex-

ceed the depressions. The same is true of the appearances on the south side of the branch, where the surface is almost level for several hundred yards; and I think that any one surveying the whole of the disturbed ground will be brought to the conclusion that there has been a general upheaval rather than a depression, and that the irregularities now observable are due to a force acting from below, which has, during the shocks, unequally raised different parts of the surface. One of the earlier geologists, while this science was in its infancy, would probably have ascribed these phenomena to the presence underneath the surface of a bed of pyrites, bituminous shale, or some other substances capable of spontaneous combustion, which had taken fire from being penetrated by a stream of water or some other accidental cause. If such a combustion were to take place at a considerable depth below the surface, and should to a great extent heat the strata above, they would thereby be expanded and thickened so as to be forced upward. Such an expansion, though it would be less in granite than in some other strata, as shown by your fellow-townsman, Col. Totten, would nevertheless, if the heated mass were thick and the elevation of temperature considerable, be sufficient to raise the surface as much as it appears to have been elevated; such expansion, however, being necessarily from its nature very gradual, would not account for the various violent shocks nor for the irregular action at the surface. On the other hand, if the burning mass were near the surface, so as to cause explosion by means of gases generated from time to time, it is scarcely conceivable that such gases, while escaping through fissures of the rock above, should fail to be observed, inasmuch as a great volume would be necessary to supply the requisite amount of force, nor is it at all probable that such a state of things would not be accompanied by a sensible change of temperature at the surface. The difficulty in the way of such a supposition is greatly increased when we consider the form of the long narrow belt acted on, and from the recurrence of the sudden violent shocks after long intervals of quiet. Such a hypothesis in fact I do not regard as entitled to more respect than another one which was suggested to me at the place. As it has no other merit than that of originality, I should not have thought it worth repeating but for the statement of fact made in support of it. While I was observing the locality, my attention was directed to an elderly man who was gliding with a stealthy step through the forest, carrying on his left shoulder a rifle, and in his right hand a small hoe, such as the diggers of ginseng use. His glances, alternating between the distant ridges and

the plants about his feet, showed that while looking for deer he was not unmindful of the wants of the inhabitants of the Celestial Empire. On my questioning him in relation to the appearances, he said that he had observed them often after the different shocks; that the appearances were changed each time at the surface; that I ought to see it just after a shock, before the rain and leaves had filled the cracks, adding that it did "not show at all now." He expressed a decided opinion that the convulsions were produced by silver under the surface. On my remarking that though I knew that that metal, in the hands of men, was an effective agent in cleaving rocks and excavating the earth, yet I had not supposed it could exert such an influence when deeply buried under ground, he stated in support of his opinion, that one of his neighbors had, on the north side of the mountain, found a spring hot enough to boil an egg. He also added that some three years since he had seen on the mountain, two miles to the north of this one, but in the direction seemingly of the line of force, a blazing fire for several hours, rising up sometimes as high as the tops of the trees, and going out suddenly for a moment at a time at frequent intervals. He declared that at the distance of a mile from where he was, the brightness was sufficient to enable him to see small objects. Several other persons in the vicinity I found subsequently professed to have seen the same light from different points of view, and described it in a similar manner. As no one of them seems to have thought enough of the matter to induce him to attempt to approach the place, though some persons represented that they had subsequently found a great quantity of " cinder" at the point, the statement of fact is not perhaps entitled to more weight than the hypothesis it was intended to support.

It is probable, however, that some difficulty will attend any explanation that can be offered in relation to the phenomena at this place. We know that the elevation of the surface of the earth is at many places undergoing a change, so gradual as not to be observed at any one time. Some of the northwestern parts of Europe, for example, are experiencing a slow upheaval equal to five or six feet in a century, while on the coast of Greenland the subsidence, or depression, is such that even the ignorant inhabitants have learned that it is not prudent for them to build their huts near the edge of the water. Similar changes are observed in various other places, but they obviously bear no analogy to the facts under consideration. Again, it is well known that earthquakes from time to time agitate violently portions of the earth's surface, of greater or less extent; that

be the only locality affected. It might be supposed that there is at this place a mass of rock, separated wholly or partially from the adjoining strata, reaching to a great depth, and resting on a fluid basin, the agitation of which occasionally would give a shock to the mass. Though such be not at all probable, yet it is conceivable that such a mass might possess the requisite shape; and if at the top, instead of being a single piece, it should have a number of irregular fragments resting on it below the surface, then it might be capable of producing inequalities observable after each successive convulsion. From the form, however, of the belt acted on, as well as from other considerations, such a hypothesis is only possible, not probable. It would perhaps more readily be conceded that there was in the solid strata below an oblong opening, or wide fissure, connected with the fluid basin below, and filled either with melted lava, or more probably with elastic gas, condensed under vast pressure, so that the occasional agitations below would be propagated to the surface at this spot. Or if we suppose that steam, at a high heat, or some of the other elastic gaseous substances, should escape through fissures from the depths below, but have their course obstructed near the surface, so as to accumulate from time to time, until their force was sufficient to overpower the resistance, then a succession of periodic explosions might occur. Such a state of things would be analogous to the manner in which Mr. Lyell accounts for the Geysers, or Intermittent Hot Springs, in Iceland, except that the intervals between the explosions in this instance are much greater than in the other. It is easy to conceive that the shocks of some former earthquakes may have produced the requisite condition in the strata at that place.

     Or, should we reject all such suppositions, it might be worth while to inquire whether this and similar phenomena may not be due to electricity? The opinion seems to have become general with men of science, that there are great currents of electricity circulating in the shell of the globe, mainly if not entirely in directions parallel to the magnetic equator. The observations and experiments of Mr. Fox have, in the opinion of a geologist so eminent as Mr. Lyell, established the fact that there are electro­magnetic currents along metalliferous veins. Taking these things to be true, it may well be that the electricity in its passage should be collected and concentrated along certain great veins. During any commotion in the great ocean of electricity, the currents along such lines, or rather where they are interrupted, might give rise to sensible shocks. The exceedingly quick vibratory motion, often observed on such occasions, seems analogous

to some of the observed effects of electricity. In the present instance the line of force appears to coincide with the direction of the magnetic needle. It is also represented that the sound accompanying the convulsions is heard more distinctly at Waynesville, twenty miles south, than it is within two or three miles to the east or west of the locality, seeming to imply that the force may be exerted in a long line, though it is more intense at a particular point. In adverting, however, to the manner in which the phenomena observed at this place might possibly be accounted for, it is not my expectation to be able to arrive at their cause. One whose attention is mainly directed to political affairs, and who at most gets but an occasional glimpse of a book of science, ought neither to assume, nor to be expected to accomplish this. I have adopted the above mode of making suggestions as to the causes, solely to enable me to explain the facts observed in a more intelligible manner than I could do by a mere detail of the appearances and events as narrated. Perhaps those whose minds are chiefly occupied with the consideration of such subjects will find an easy solution of these phenomena. Should this letter be instrumental in eliciting information in relation to similar disturbances elsewhere in the Alleghany range, then its publication may answer some valuable purpose.

Messrs. Gales & Seaton.

P. S. Since writing this letter, I have been apprized of a similar convulsion which occurred six or seven years ago, at a place some forty miles distant from this in a southwesterly direction. My informant says that at his house the ground was agitated for some minutes during a rumbling sound, and that a few miles off, the earth was rent and broken for the distance of two miles in length and nearly a half mile in breadth. Though I have not seen the locality, I have no doubt of the truth of the statement, nor of the general resemblance of the phenomena to those I have described above.

To J. S. Skinner, Esq.

House of Representatives, Feb. 3, 1844.

Dear Sir: Your favor of the 30th ultimo was received a day or two since, and I now avail myself of the very first opportunity to answer it. I

do so most cheerfully, because, in the first place, I am happy to have it in my power to gratify in any manner one who has done so much as yourself to diffuse correct information on subjects most important to the agriculture of the country; and, secondly, because I feel a deep interest in the subject to which your inquiries are directed.

You state that you have directed some attention to the sheep husbandry of the United States, in the course of which it has occurred to you that the people of the mountain regions of North Carolina, and some of the other Southern States, have not availed themselves sufficiently of their natural advantages for the production of sheep. Being myself well acquainted with the western section of North Carolina, I may perhaps be able to give you most of the information you desire. As you have directed several of your inquiries to the county of Yancey, (I presume from the fact, well known to you, that it contains the highest mountains in any of the United States,) I will, in the first place, turn my attention to that county. First, as to its elevation. Dr. Mitchell, of our University, ascertained that the bed of Tow river, the largest stream in the county, and at a ford near its centre, was about twenty-two hundred feet above the level of the ocean. Burnsville, the seat of the court-house, he found to be between 2,800 and 2,900 feet above it. The general level of the county is, of course, much above this elevation. In fact, a number of the mountain summits rise above the height of six thousand feet. The climate is delightfully cool during the summer: there being very few places in the county where the thermometer rises above 80° on the hottest day. An intelligent gentleman who passed a summer in the northern part of the county (rather the more elevated portion of it) informed me that the thermometer did not rise on the hottest days above 76°.

You ask, in the next place, if the surface of the ground is so much covered with rocks as to render it unfit for pasture? The reverse is the fact; no portion of the county that I have passed over is too rocky for cultivation, and in many sections of the county one may travel miles without seeing a single stone. It is only about the tops of the highest mountains that rocky precipices are to be found. A large portion of the surface of the county is a sort of elevated table-land, undulating, but seldom too broken for cultivation. Even as one ascends the higher mountains, he will find occasionally on their sides fiats of level land containing several hundred acres in a body. The top of the Roan (the highest mountain in the county except the Black) is covered by a prairie for ten miles, which affords a rich

I have been somewhat prolix in my observations on this county, because some of your inquiries were directed particularly to it, and because most of what I have said of Yancey is true of the other counties west of the Blue Ridge. Haywood has about the same elevation and climate of Yancey. The mountains are rather more steep, and the valleys somewhat broader; the soil generally not quite so deep, but very productive, especially in grasses. In some sections of the county, however, the soil is equal to the best I have seen.

Buncombe and Henderson are rather less elevated—Ashville and Hendersonville, the county towns, being each about 2,200 feet above the sea. The climate is much the same, but a very little warmer. The more broken portions of these counties resemble much the mountainous parts of Yancey and Haywood, but they contain much more level land. Indeed the greater portion of Henderson is quite level. It contains much swamp land, which, when cleared, with very little if any drainage, produces very fine crops of herdsgrass. Portions of Macon and Cherokee counties are quite as favorable, both as to climate and soil, as those above described. I would advert particularly to the valleys of the Nantahalah, Fairfield, and Hamburg, in Macon, and of Cheoh, in Cherokee. In either of these places, for a comparatively trifling price, some ten or fifteen miles square could be procured, all of which would be rich, and the major part sufficiently level for cultivation, and especially fitted, as their natural meadows indicate, for the production of grass.

In conclusion, I may say that, as far as my limited knowledge of such matters authorizes me to speak, I am satisfied that there is no region that is more favorable to the production of sheep than much of the country I have described. It is every where healthy and well watered. I may add, too, that there is water power enough in the different counties composing my Congressional district, to move more machinery than human labor can ever place there—enough, certainly, to move all now existing in the Union. It is also a rich mineral region. The gold mines are worked now to a considerable extent. The best ores of iron are found in great abundance in many places; copper, lead,* and other valuable minerals exist.

* Since writing this letter I have discovered there the diamond, platina, blue corundum in large masses, of brilliant colors, and the most splendent lustre, sapphire, ruby, emerald, euclase, amethyst ; also in various localities, zircon, pyropian garnet, chrome ore ; and manganese, and barytes in large veins; likewise plumbago of the finest quality.

That must one day become the great manufacturing region of the South. I doubt if capital could be used more advantageously in any part of the Union than in that section.

For a number of years past the value of the live stock (as ascertained from books of the Turnpike Company) that is driven through Buncombe county is from two to three millions of dollars. Most of this stock comes from Kentucky and Ohio, and when it has reached Ashville it has travelled half its journey to the more distant parts of the Southern market, viz. Charleston and Savannah. The citizens of my district, therefore, can get their live stock into the planting States south of us at one half the expense which those of Kentucky and Ohio are obliged to incur. Not only sheep, but hogs, horses, mules, and horned cattle can be produced in many portions of my district as cheaply as in those two States.

Slavery is, as you say, a great bugbear, perhaps, at a distance; but I doubt if any person from the North, who should reside a single year in that country, whatever might be his opinions in relation to the institution itself, would find the slightest injury or inconvenience result to him individually. It is true, however, that the number of slaves in those counties is very small in proportion to the whole population.

I have thus, sir, hastily endeavored to comply with your request, because you state that you would like to have the information at once. Should you rind my sketch of the region a very unsatisfactory and imperfect one, I hope you will do me the favor to remember that the desk of a member during a debate is not the most favorable position for writing an essay.

With very great respect, yours,

T. L CLINGMAN.

J.S. Skinner, Esq.

To the Editor of the Highland Messenger.

You published a few weeks since an extract from an article in Silliman's Journal, contributed by Prof. Shepard, in which he described a diamond sent him from this region a few months since. As that extract excited some interest in the minds of a number of my friends who are engaged in the mining business, I inclose you a letter from Prof. Shepard, the publication of which I am sure would be acceptable to many of your readers. I may remark in explanation, that within the last few

years I have sent Prof. Shepard some hundreds of specimens of minerals collected in this and some of the other western counties of the State. In some instances a doubt as to the character of a particular mineral induced me to take this course, but more frequently it was done to gratify those of my acquaintances who wished to have their specimens examined by one in whose decision there would be absolute acquiescence. I knew too, that I should by these means be able favorably to make known to the public the existence in Western North Carolina, of such minerals as might be valuable in a commercial point of view, or interesting to the scientific world. The letter which I send you, was received in reply to an inquiry directed to Prof. Shepard, as to what was his opinion generally in relation to the minerals of this region, and what he thought of the propriety of a more careful survey of it than has hitherto been made. The answer, though merely in reply to my inquiries, is of such a character that I feel quite sure that its publication will be alike creditable to the writer and beneficial to the public. Even should it fail to produce any such impression on the minds of our legislators as might induce them to direct a complete geological survey of the State, its publicity may in other respects prove beneficial.

I have been pleased to observe that the letter of Prof. Mitchell, in relation to some of the minerals of this region, which appeared in your paper a year or two since, aroused the attention of a number of persons to that subject, and has been the means of bringing under my observation several interesting minerals. By going (whenever leisure has been afforded me,) to examine such localities as from their singular appearance or any peculiarity of external character, had aroused the attention of persons in the neighborhood,—I have induced many to manifest an interest in such subjects, so that there is in this legion a considerable increase in the number of individuals who will lay up and preserve for examination singular looking minerals. Others are deterred from so doing, lest they should be laughed at by their neighbors as unsuccessful hunters of mines. Doubtless they deserve ridicule, who, so ignorant of mineralogy as not to be able to distinguish the most valuable metallic ores from the most common and worthless rocks, nevertheless spend their whole time in travelling about the country under the guidance of mineral rods or dreams, in search of mines. But, almost every one may without serious loss of time and with trifling inconvenience to himself, preserve for future examination specimens of the different mineral substances he meets with in his rambles. He

ought to remember that by so doing he may have it in his power to add to the knowledge, wealth and happiness of his countrymen. Partially separated as this region of country is by its present physical condition from the commercial world, it is of the first consequence to its inhabitants that all its resources should be developed. Opening valuable mines, besides diverting labor now unprofitably, because excessively, applied to agriculture, would attract capital from abroad and furnish a good home market to the farmer.

Should the proposed Railroad from Columbia to Greenville, S. C., be completed, I am of opinion that the manganese and chrome ores in this and some of the adjoining counties would be profitably exported. Though the veins of sulphate of baryta in the northern part of this county, contain pure white varieties suitable to form an adulterant in the manufacture of the white lead of commerce, yet for want of a navigable stream, it is not probable that they will ever be turned to account in that way. They have, however, at some points, a metallic appearance at the surface, they lie at right angles to the general direction of the veins of the country, go down vertically, and being associated abundantly with several varieties of iron pyrites, oxides of iron, fluor spar and quartz, and containing traces of copper and lead, will doubtless at no very distant day, be explored to a greater or less extent. There is not a single county west of the Blue Ridge, that does not contain in abundance rich iron ores. In some instances these deposites are adjacent to excellent water power and limestone, and are surrounded by heavily timbered cheap lands. The sparry carbonate of iron, or steel ore, of which a specimen some years since, fell under the observation of Prof. Mitchell, though he was not able to ascertain the locality from which it came, is abundant at a place rather inaccessible in the present condition of the country. It is not probable that in our day the beautiful statuary marble of Cherokee, both white and flesh-colored, will be turned to much account for want of the means of getting it into those markets where it is needed. Besides the minerals referred to in Prof. Shepard's letter, some of the ores of copper exist in the western part of this State. I have the carbonate, (green malachite,) the black oxide, and some of the sulphurets. Whether, however, these, as well as the ores of lead and zinc, (both the carbonate and sulphuret exist here,) are in sufficient abundance to be valuable, cannot be ascertained without further examination than has yet been made.

Many persons are deterred from making any search, and are discour-

aged because valuable ores are not easily discovered on the surface of this country. This is not usually the case any where. Gold, it is true, because it always exists in the metallic state, and because it resists the action of the elements better than any other substance, remains unchanged, while the gangue, or mineral containing it crumbles to pieces and disappears, and hence it is easily found about the surface by the most careless observer. Such, however, is not generally the case with metallic ores. On the contrary, many of the best ores would, if exposed to the action of the elements, in progress of time be decomposed, or so changed from the appearances which they usually present when seen in cabinets, that none but a practised eye would detect them at the surface. In the counties west of the Blue Ridge, there has been as yet no exploration to any depth beneath the surface of the ground, with perhaps the single exception of the old excavations in the county of Cherokee. According to the most commonly received Indian tradition, they were excavated more than a century ago, by a company of Spaniards from Florida. They are said to have worked there for two or three summers, to have obtained a white metal, and prospered greatly in their mining operations, until the Cherokees, finding that if it became generally known that there were valuable mines in their country, the cupidity of the white men would expel them from it, determined in solemn council to destroy the whole party, and that in obedience to that decree no one of the adventurous strangers was allowed to return to the country whence they came. Though this story accords very well with the Indian laws which condemned to death those who disclosed the existence of mines to white men, yet I do not regard it as entitled to much credit. At the only one of these localities which I have examined, besides some other favorable indications, there is on the surface of the ground in great abundance that red oxide of iron, which from its being found in Germany above the most abundant deposites of the ores of lead and silver, has been called by the Germans the Iron Hat. Also something resembling that iron ore rich in silver, which the Spaniards called pacos, is observable there. It seems more probable, therefore, that some of those companies of enterprising Spaniards, that a century or two since were traversing the continent in search of gold and silver mines, struck by these appearances, sunk the shafts in question and soon abandoned them as unproductive. But which of these is the more probable conjecture, cannot perhaps be determined, until some one shall

be found adventurous enough to reopen those old shafts.    I am, however, keeping your readers too long from the interesting letter of Prof. Shepard.

T. L. CLINGMAN.

New Haven, Conn., Sept. 15, 1746,

Hon. Mr. Clingman,—Dear Sir:—To your inquiry of what I think of the mineral resources of Western North Carolina, it gives me pleasure to say that no part of the United States has impressed me more favorably than the region referred to. It is proper, however, to state, that my acquaintance with it is not the result of personal observation, but has been formed from a correspondence of several years standing with yourself and Dr. Hardy, and from the inspection of numerous illustrative specimens supplied to me at different times by my colleague, Dr. S. A. Dickson. of Charleston, S. C., and by the students of a Medical College of South Carolina, who have long been in the habit of bringing with them to the college samples' of the minerals of their respective neighborhoods. I may add to these sources of information, the mention of not unfrequent applications made to me by persons from North Carolina, who have had their attention called to mines and minerals, with a view to their profitable exploration. Nor shall I ever forget the pleasure I experienced a year or two since, on being waited upon in my laboratory by a farmer from Lincolnton, who had under his arm a small trunk of ore in lumps, which he observed that he had selected on account of their size, from the gold washings of his farm during the space of a single year. The trunk contained not far from twelve hundred dollars in value, and one of the specimens weighed two hundred and seventy-five dollars.

I have recognized in the geological formation of the southwestern counties of North Carolina, the same character which distinguishes the gold and diamond region of the Minas Geraes of Brazil, and the gold and platina district (where diamonds also exist) of the Urals, in Siberia. It is this circumstance, beyond even the actual discoveries made with us, that satisfies my mind of the richness of the country in the precious metals and the diamond. The beautiful crystal of this gem which you sent me last spring, from a gold washing in Rutherford, however, establishes the perfect identity of our region with the far-famed auriferous and diamond countries of the South and the East.

Neither can there remain any doubt concerning the existence of valuable deposites of manganese, lead, chrome and iron, in your immediate vicinity, to which I think we are authorized to add zinc, barytes and marble. I have also seen indications of several of the precious stones, besides the diamond, making it on the whole, a country of the highest mineralogical promise.

Enough has already been developed, as it appears to me, in the minerals of the region under consideration, to arouse the attention of prudent legislators to this fertile source of prosperity in a State. If a competent surveyor of the work were obtained, under whose direction a zealous and well-instructed corps of young men, (now easily to be obtained from those States in which such enterprises are just drawing to a close,) could take the field, I have no doubt that numerous important discoveries would immediately be made, and that the entire outlay required for carrying forward the work, would in a very short time be many times over returned to the people from mineral wealth, which now lies unobserved in their very midst. But the highest advantages of such a survey would no doubt prove with you as it has done elsewhere, to be the spirit of inquiry which it would impart to the population generally, producing among their own ranks an efficient band of native mineralogists and geologists, whose services, in their own behalf, in that of their neighbors and the State at large, would, in a few years, greatly outweigh all that had been achieved by the original explorers. It is thus in the States of New-England, New-York, Ohio, Pennsylvania, New Jersey and Maryland, that there are scattered every where through those communities, numbers of citizens, who having first had their attention called to the subject by the scientific men appointed by the Legislature, have now become fully competent to settle most of the questions which arise relating to the values of the unknown mineral substances, which from time to time are submitted by their less informed neighbors for determination. A very observable impulse has in this way been given to the development of underground wealth; and many valuable mines are in the course of active exploration, which but for these surveys and the attendant consequences of them, would now remain not only unproductive but unknown. Nor is the mere mineral yield of these mines to be considered in determining the advantages that accrue to a community from such enterprises. The indirect results to the neighborhood in which the mines are situated, are often very great; such for example as those flowing from the increased demand for farming produce, from the free circulation of

It appears that the valley of the French Broad is a trough, or depression, extending quite across the great back-bone of the United States, having the parallel, but considerably higher valleys of the Nolachucky and Pigeon on its two sides. Ivy Ridge is the boundary of this valley on the north-east, the ford of Ivy creek, near Solomon Carters, having very nearly the height of Ashville. The difference of temperature and climate corresponds to the indications of the barometer, grain and wild fruits ripening sooner about Ashville, than in the neighborhood of either Burnsville or Waynesville. At the ford of the Tuckaseege, on the road to Franklin, we are at the bottom of another deep and warm valley, but this does not, like that of the French Broad, extend across the whole range of the Alleghanies.

These measurements are not altogether without value, to the people of Haywood and Macon, showing as they do, what is the amount of obstacle that has to be overcome in carrying a road from Tennessee into South Carolina, along the Tuckaseege. Such a road should be made, or rather the existing one should be greatly improved, and the route altered in some places. There is likely to be a good deal of travel along it, but the gap in the Blue Ridge, where it is to pass, is about 1500 feet higher than that at the head of the French Broad.

There are but two routes by which the highest peaks of the Black Mountains can be reached, without an amount of labor which few people are willing to undergo. One is by the head of Swanannoa, This brings us to a point a little higher than the top of the White Mountains in New Hampshire. The other is from the south fork of Tow. It is represented as quite practicable, and leads to the highest summit.

Agriculture.—The mountain counties, Ashe, Yancey, Buncombe, Hen-

derson, Haywood and Macon, do not appear to have adopted fully those modes of culture which are the best suited to their soil and climate, and which are likely ultimately to prevail. For this two reasons may be assigned.

1.   The great amount of travel, through the counties of Ashe, Henderson and Buncombe, (but especially the two last,) between the Atlantic states and the West, has created a demand for the different kinds of grain,
and given a direction to the industry of the population of those counties, which but for the circumstance mentioned, would be neither natural nor profitable.  The roads have consumed all the corn that could be raised.  The practice of the farmers living near the roads, which will answer very well for them, (especially if somewhat more attention be paid to the cultivation of the grasses), may be expected to have an under influence in the remote parts of those counties.

2.   The families by whom these counties were settled, were from below the ridge, and carried with them into the mountain region, the kind of husbandry to which they have been accustomed in the warmer and drier parts from which they came. It is only gradually that men change the habits and practices of their earlier days. This influence of custom is exhibited on the northernmost range of counties in North Carolina, along the Virginia line, where the culture of tobacco prevails much more extensively than a little farther south, where the soil is equally well adapted to the growth of that noxious weed.

The latitude and elevation—and of course the temperature of the mountain counties as far as it depends upon these two, are very nearly the same with those of ancient Arcadia—the country of herdsmen and shepherds. Their soil is different, having been formed by the decomposition of primitive rocks—granite, gneiss and mica slate—whilst limestone abounds in Arcadia, as well as other parts of Greece. But it is to the raising of cattle and sheep and the making of butter and cheese for the counties below the ridge, that it may be expected there will be a tendency in the industry of the mountain region for many years. The quantity of rain falling there, is greater than in the eastern parts of the state, and luxuriant meadows of the most valuable grasses, but especially of timothy, may be easily formed. This is for winter food. But the summer pastures, too, are susceptible of great improvement.

Whilst the Indians held possession of the country it was burnt over every year. The fire destroyed the greater number of the young trees.

that were springing up, and the large ones remained thinly scattered, like the apple trees in an orchard with large open spaces between. In these, the different kinds of native vines and other wild plants,—pea vine, &c., contended for the mastery, and each prevailed and excluded the other according to the vigor of its growth. Macon county still exhibits in some parts the appearance which the whole back country of North Carolina may be supposed to have borne when the first settlements of the whites were made. But after the Indians had been removed and large quantities of stock were introduced, the cattle and horses lent their aid in this contest of the different vegetable species and in favor of the worst kinds. They ate out and destroyed such as they found palatable and suitable for the nourishment of animals, whilst such as are worthless were permitted to grow and occupy the ground. In the mean time the annual firing of woods that had been practised by the Indians having ceased, bushes and small trees have overspread and shaded a large space that was formerly covered with herbage. For these two reasons, therefore, because the best kinds of vegetables have been in a great measure eaten out, and destroyed, and because of the thickening of the forests, the range (even if the population were still the same) would be greatly inferior to what it was fifty years ago.

It is necessary here as in other cases that the industry and ingenuity of man should come in to direct, and to some extent, control the operations of nature. The best grasses—best for pasturage, must be introduced and made to take the place of such as are worthless. The milk, butter, and cheese would be improved in quality as well as increased in quantity. As the wild onion, where eaten by cows, gives milk a flavor that is intolerable to some persons, so it may be expected that bitter and unpalatable weeds of every kind will give it a wild and savage taste; that it will be inferior in purity and richness to such as is yielded where the sweetest and best grasses are the only food. It appeared to me as I rode down from the Flat Rock to Ashville that there were very extensive tracts in Henderson and in the southern part of Buncombe now almost waste and worthless, which would, in the course of a few years, be converted into artificial pastures; not the most fertile in the world—but such as would amply repay an outlay of capital upon them; that the marshes and low grounds would be drained, and rank timothy take the place of sedge and other coarse grasses that afford no nourishment. In the immediate neighborhood of the Flat Rock I saw that the good work had been begun and made a considerable progress.
