SALT SULPHUR SPRINGS.
In the County of Monroe, twenty-six miles southwest from the White Sulphur, are the Salt Sulphur Springs; they are two miles from Union, the county seat. From a pamphlet written by Dr. Mütter of Philadelphia, we copy the following account of these Springs:
"The Salt Sulphur Springs, three in number, are situated in the county of Monroe, in 37½° north latitude, 5° longitude west of Philadelphia, and at an elevation of about 1400 feet above tide water. All the springs are situated on 'Indian Creek,' a small limestone stream, which rises in a valley a few hundred yards above the Old or Sweet Spring, and after pursuing its 'devious way' for about 23 miles in a southwest direction, finally empties into New River, in Monroe County. It derives its name from the circumstance of the Indians, who, in former times were in the habit of entering the valley of Virginia from Kentucky and Ohio, almost invariably making it their 'Camping Stream.' Their graves, along with other traces of their frequent resort to this particular spot, are occasionally met with at the present day.
"The Salt Sulphur is hemmed in on every side by mountains. To the south and east, in full view, and about 10 miles distant, is Peters Mountain; due north, and about 14 miles distant, is a low spur of the Alleghany; and west, it is bounded by Swope's Mountain, at or near the base of which, are the two principal springs.
"It appears from the statement of some of the 'oldest inhabitants,' that the Old or Sweet Spring was discovered in 1802 or 1803 by Alexander Hutchinson, Esq., who was engaged in boring for salt along Indian Creek. For several years it enjoyed much celebrity, and was annually the resort of a large company.
