The only minerals in _Mississippi_, are amethyst, of which one crystal has been found; potter's clay, at the Chickasaw Bluffs, and near Natchez; sulphuret of lead in small quantities, about Port Gibson; and sulphate of iron. Petrified trunks of trees are found in the bed of the Mississippi, opposite Natchez. In Arkansas Territory are various species. Here may be found the native magnet, or magnetic oxide of iron, possessing strong magnetic power. Iron ores are very abundant. Sulphate of copper, sulphuret of zinc, alum, and aluminous slate are found about the cove of Washitau, and the Hot Springs. Buhr stone of a superior quality exists in the surrounding hills. The hot springs are interesting on account of the minerals around them, the heat of their waters, and as furnishing a retreat to valetudinarians from the sickly regions of the south. They are situated on the Washitau, a large stream that empties itself into Red river. The _lead mines_ of Missouri have been worked for more than a century. They are distributed through the country from thirty to one hundred miles southwest from St. Louis, and probably extend through the Gasconade country. Immense quantities of iron ore exist in this region. Lead is found in vast quantities in the northern part of Illinois, the south part of the Wisconsin Territory, and the country on the opposite side of the Mississippi. These mines are worked extensively. Native copper in large quantities is found in the same region. Large quantities of iron ore is found in the mountainous parts of Tennessee and Kentucky, where furnaces and forges have been erected. Also, in the hilly parts of Ohio, particularly at the falls of Licking four miles west of Zanesville, and in Adams and Lawrence counties near the Ohio river. With _iron ore_ the West is profusely supplied. _Bituminous coal_ exists in great profusion in various parts of the Western Valley. The hills around Pittsburg are inexhaustible. It extends through many portions of Ohio and Indiana. Nearly every county in Illinois is supplied with this valuable article. Missouri, Kentucky, and Tennessee have their share. Immense quantities are found in the mountains along the Kenhawa, in Western Virginia, and it is now employed in the manufacture of salt. The Cumberland mountains in Tennessee contain immense deposits.
