large, standing in the middle of the avenue, and is encircled with many smaller ones. Columns of spar, fluted and studded with knobs of spar and stalactites, drapery of various colors, superbly festooned and hung in the most graceful manner, are shewn with the greatest brilliancy from the reflection of lamps. ‘A part of the haunted chamber lies directly over the bat room, which passes under it, without having any connection with it. I was led into a very narrow defile on the left side of this chamber, and about a hundred yards from Wilkins’s armed chair, over the side of a smooth limestone rock, ten or twelve feet, which we passed with much precaution, for had we slipped from our hold, we had gone to that “bourne whence no traveller returns,” if I may judge from a cataract of water, whose dismal sound we heard at a very considerable distance in this pit, and nearly under us. However, we crossed in safety, clinging fast to the wall, and winding under the haunted chamber, and through a very narrow passage for thirty or forty yards, when our course was west, and the passage twenty or thirty feet in width, and from ten to eighteen feet high, for more than a mile. The air was pure and delightful in this, as well as in other parts of the cave. At the farther end of this avenue, we came upon a reservoir of water, very clear and delightful to the taste, apparently having neither inlet nor outlet. Within a few yards of this reservoir of water, on the right hand of the cave, there is an avenue leading to the north-west. We had entered it but forty feet, when we came to several columns of the most brilliant spar, sixty or seventy feet in height, and almost perpendicular, which stand in basins of water, that comes trickling down their sides, then passes off silently from the basin, and enters the cavities of stone, without being seen again. These columns of spar, and the basins they rest in, for splendor and beauty, surpass every similar work of art I ever saw. We passed by these columns, and entered a small but beautiful chamber, whose walls were about twenty feet apart, and the arch not more than seven feet high, white as white-wash could have made it; the floor was level as far as I could see, which was not a great distance, as I found many pit-holes in my path, that appeared to have been lately sunk, and which induced me to return. We returned by the beautiful pool of water, which is called the pool of Clitorius, after the _Fons Clitorius_ of the classics, which was so pure and delightful to the taste, that, after drinking of it, a person had no longer a taste for wine. On our way back to the narrow defile, I found some difficulty in keeping my lights, for the bats were so numerous and continually in our faces, that it was next to impossible to get along in safety. I brought this trouble on myself, by my own want of foresight, for as we were moving on, I noticed a large number of these bats hanging by their hind legs to the arch, which was not a foot
