In the western part of the county are several medicinal springs, whereto numbers of people resort towards the latter end of summer, as much for the sake of escaping the heat in the low country, as for drinking the waters. Those most frequented are called the Sweet Springs, and are situated at the foot of the Alleghany Mountains. During the last season upwards of two hundred persons resorted to them with servants and horses. The accommodations at the springs are most wretched at present; but a set of gentlemen from South Carolina have, I understand, since I was there, purchased the place, and are going to erect several commodious dwellings in the neighbourhood, for the reception of company. Besides these springs there are others in Jackson’s Mountains, a ridge which runs between the Blue Mountains and the Alleghany. One of the springs here is warm, and another quite hot; a few paces from the latter a spring of common water issues from the earth, but which, from the contrast, is generally thought to be as remarkable for its coldness as the water of the adjoining one is for its heat: there is also a sulphur spring near these; leaves of trees falling into it become thickly incrusted with sulphur in a very short time, and silver is turned black almost immediately. At a future period the medicinal qualities of all these springs will probably be accurately ascertained; at present they are but very little known. As for the relief obtained by those persons that frequent the Sweet Springs in particular, it is strongly conjectured that they are more indebted for it to the change of the climate than to the rare qualities of the water. ------------------------------------------------------------------------ +LETTER + XVII. _Description of the celebrated Rock Bridge, and of an immense Cavern.—Description of the Shenandoa Valley.—Inhabitants mostly Germans.—Soil and Climate.—Observations on American Landscapes.—Mode of cutting down Trees.—High Road to Kentucky, behind Blue Mountains. — Much frequented.—Uncouth, inquisitive People.—Lexington.—Staunton.—Military Titles very common in America.—Causes thereof.—Winchester._ [Illustration: VIEW _of the_ ROCK BRIDGE. ] Winchester, May.
