hundred feet in length; the angle of defcent is about 45 degrees, The roof of this cavern is of rock, through which the water is continually percolating. The ftalactites which hang from the roof ap like icicles on the eves of houses, and are continually increasing in number and magnitude. The bottom and fides are daily incruft, ing with fpar and other mineral fubftances. On the fides of this fubterraneous hall are tables, chairs, benches, &c. which appear to have been artificially carved. This richly ornamented room, when illuminated with the candles of the guides, has an enchanting effect upon the eye of the fpectator. The general cause of these astonishing appearances, we conclude, from the various circumstances ac companying them, is the water filtrating flowly through the incum bent ftrata; and taking up in its paffage a variety of mineral substances, thus becoming faturated with metallic particles, gradually exfuding on the surface of the caverns and fiffures, in a quiefcent ftate, the aqueous particles evaporate, and leave the mineral fubstances to unite according to their affinities.

At the end of this cave is a circular hole, fifteen feet deep, apparently hewn out in a conical form, enlarging gradually as you descend, in the form of a sugar loaf; at the bottom is a spring of fresh water in continual motion, like the boiling of a pot; its depth has never been sounded.

In fome low lands over against the great Ox Bow, a remarkable fpring was discovered about twenty years fince; it dries up once in two or three years, and burfts out in another place; it has a strong fmell of fulphur, and throws up continually a peculiar kind of white fand, and when the water is left to fettle, a thick yellow fcum rifes on

its top.
