After a lapse of nearly an hour, he descended by what is called the “passage of the chimney,” and joined the other guide. Thence returning to the chief area or city, where the lamps were trimmed for the last time, he entered the spacious avenue which led to the second hoppers. Here he met with various curiosities, such as spars, petrifactions, &c.; and these he brought away, together with _a mummy_ which was found at the second hoppers. He reached the mouth of the cave about three in the morning, nearly exhausted with nineteen hours of constant fatigue. He nearly fainted on leaving it, and on inhaling the vapid air of the atmosphere, after having so long breathed the pure air occasioned by the niter of the cave. His pulse beat stronger when in the cave, but not so quick as when on the surface. Here the doctor observes that he has hardly described half the cave, not having named the avenues between its mouth and the second hoppers. This part of his narrative is of equal interest with what has been already given. He states that there is a passage in the main avenue, upward of nine hundred feet from the entrance, like that of a trap-door. By sliding aside a large flat stone, you can descend sixteen or eighteen feet in a very narrow defile, where the passage comes on a level, and winds about in such a manner, as to pass under the main passage without having any communication with it, at length opening into the main cave by two large passages just beyond the second hoppers. This is called the “glauber-salt room,” from salts of that kind being found there. Next come the sick room, the bat-room, and the flint-room, together with a winding avenue, which, branching off at the second hoppers, runs west and south-west for more than two miles. It is called the “haunted chamber,” from the echo within: its arch is very beautifully incrusted with limestone spar; and in many places the columns of spar are truly elegant, extending from the ceiling to the floor. Near the center of this arch is a dome, apparently fifty feet high, hung in rich drapery, festooned in the most fanciful manner for six or eight feet from the hangings, and in colors the most rich and brilliant. By the reflection of one or two lights, the columns of spar and the stalactites have a very romantic appearance. Of this spar, a large elevation, called “Wilkin’s arm-chair,” has been formed in the center of the avenue and encircled with many smaller ones. The columns of the spar, fluted and studded with knobs of spar and stalactites; the drapery of the various colors superbly festooned and hung in the most graceful manner, these are shown with the greatest brilliancy by the reflection of the lamps.
