The country westward of the Alleghany abounds with springs of common salt. The most remarkable we have heard of are at Bullet's-lick, the Big-bones, the Blue-licks, and on the north fork of Holston. The area of Bullet's-lick is of many acres. Digging the earth to the depth of three feet the water begins to boil up, and the deeper you go and the drier the weather, the stronger is the brine. A thousand gallons of water yield from a bushel to a bushel and a half of salt, which is about eighty pounds of water to one pound of salt. So that sea-water is more than three times as strong as that of these springs. A salt spring has been lately discovered at the Turkey foot on Yohogany, by which river it is overflowed, except at very low water. Its merit is not yet known. Dunning's lick is also as yet untried, but it is supposed to be the best on this side the Ohio. The salt springs on the margin of the Onondago lake are said to give a saline taste to the waters of the lake. There are several medicinal springs, some of which are indubitably efficacious, while others seem to owe their reputation as much to fancy and change of air and regimen, as to their real virtues. None of them having undergone a chemical analysis in skilful hands, nor been so far the subject of observations as to have produced a reduction into classes of the disorders which they relieve; it is in my power to give little more than an enumeration of them. The most efficacious of these are two springs in Augusta near the first sources of James' river, where it is called Jackson's river. They rise near the foot of the ridge of mountains generally called the Warm spring mountains, but in the maps Jackson's mountains. The one distinguished by the name of the Warm spring, and the other of the Hot spring. The Warm spring issues with a very bold stream, sufficient to work a grist mill and to keep the waters of its basin, which is thirty feet in diameter, at the vital warmth, viz. 96° of Fahrenheit's thermometer. The matter with which these waters is allied is very volatile; its smell indicates it to be sulphureous, as also does the circumstance of its turning silver black. They relieve rheumatisms. Other complaints also of very different natures have been removed or lessened by them. It rains here four or five days in every week.
