Note. The principal cave is from 50 to 80 Plwide k about
30 ft, high in general At the big room it is 100 ft. wide,
440 or 50 ft high It has been explored about 1 miles
from the termination of the narrows. The Clay impregnated
with nitre has been found, to be generally about 5ft. deep,
extending quite across the cave. Underthis Clay is a vast body
of fine dry sand the depth of which has never bun ascertained
The Clay in the principal cave produces 6 Us of Salt Petre to
every bushel – The sand produces 1listo the bushel

wuch waste in base The entrance of the cave is, in this side, wood two-thirds of the way up. It extends into the earth about 300 feet, branching into subordinate caverns, sometimes ascending a little, but more gen 136] erally descending, and at length terminates, in two different places, at basons of water of unknown extent, and which I should judge to be nearly on a level with the water of the river; however, I do not think they are formed by refluent water from that, because they are never turbid; because they do not rise and fall in correspondence with that in times of flood, or of drought; and because the water is always cool. It is probably one of the many reservoirs with which the interior parts of the earth are supposed to abound, and yield supplies to the fountains of water, distinguished from others only by being accessible. The vault of this cave is of solid lime-stone, from 20 to 40 or 50 feet high; through which water is continually percolating. This, trickling down the sides of the cave, has incrusted them over in the form of elegant drapery; and dripping from the top of the vault, generates on that, and on the base below, stalactites of a conical form, some of which have met and formed massive columns.

Another of these caves is near the North mountain, in the County of Frederic, on the lands of Mr. Zane. The entrance into this is on the top of an extensive ridge [37]. You descend 40 or 40 feet, as into a well, from whence the cave then extends, nearly horizontally, 400 feet into the earth, preserving a breadth of from so to go feet, and a height of from 5 to 12 feet. After entering this cave a few feet, the mercury, which in the open air Was gu" toap to $7", of Farenheit's thermometer, answering to **' of Reaumur's, and it continued at that to the remotest parts of the cave The uniform temperature of the cellars of the obavrvatory of Parts, which are go feet deep, and of all subterranean cavillea of any depth, where no chymical agents may be supposed to produce a tactitious heat, has been found to be 10°. of Reaumur, equal to 543". of Farenheit. The temperature of the cave above mentioned so nearly corresponds with this, that the differeho may be ascribed to a difference of instruments.

At the Panther gap, in the ridge which divides the waters of the Cow and the Calf pasture, is what is called the Blowing cave.
