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, crome 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 capital, the improvement of roads, and the general stimulus which is always imparted by successful enterprise to the industry of a country. I may be permitted to add in conclusion also, that an important service is always rendered true science, in restraining the uninformed from unprofitable adventures.

I have a wish to see the public survey of North Carolina undertaken, not only on account of its economical bearings, but from the conviction with which I am impressed, that it will equally promote the progress of science, and elevate the character of our country at large.

I have the honor to remain very truly and obediently yours.

CHARLES UPHAM SHEPARD.

To Hon. T. L. Clingman, but originally published in the New-York Albion.

My Dear Sir,—I promised my friends in the Western counties that they should hear from me through the Highland Messenger, and to the editor of that paper that he should receive one or two communications. As the person who undertakes to inform the public on subjects not strictly in the line of his profession is likely to fall into some errors, and to say some things which will not be thought very wise, I have wished that what I have to offer, might, before going to press, pass under the eye of one, who, like yourself, has long taken a deep interest in every thing connected with the mountain region, is well acquainted with the larger part of it, and in whose friendly feeling I could fully rely. The statements and remarks that are to follow, will fall naturally under the four heads of Elevation of the Country and Height of the Mountains, Soil and Agriculture, Minerals and Scenery.

The elevation of the highest mountain peaks was ascertained by me within certain limits of accuracy about eight years ago. So little was known about them before that time, that the Grandfather was commonly regarded as the highest of all. With the view of coming somewhere near the truth, one barometer was stationed at Morganton, and another carried to the tops of the mountains. Their elevation above that village was thus ascertained; but in order to get their height above the level of the sea, that of Morganton must be known, and for this there were no data in which implicit confidence could be placed. I finally fixed upon 968 feet as a moderate estimate, and in my desire to avoid an extravagant and incredible result, it now appears that the elevation assigned to Morganton, and therefore to all the heights measured, was somewhat too small.
