MINERAL RESOURCES OF THE WEST.
A LETTER TO CHARLES G. HAINES, ESQ., SECRETARY OF THE ASSOCIATION
FOR THE PROMOTION OF INTERNAL IMPROVEMENTS AT NEW YORK.
New York, October 5th, 1819.
Sir: In reply to your communication of the 4th inst., I submit the subjoined remarks on the following questions:—
I. "To what extent are the lead, and other mines, worked in our western country, either by the United States' government, or by individuals?"
In the extensive region to which this inquiry has allusion, are found numerous ores, salts, ochres, and other minerals; and the catalogue is daily increasing, by the discovery of new substances, which promise to become important to the commerce of the western country; but the only mines worked are those of lead, iron, and coal.
