armed chair, which is very 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 higher than my head. I took my cane and gave a sweep the whole length of it, when down they fell; but soon, like so many imps, they tormented us until we reached the narrow defile, when they left us. We returned by Wilkins’s armed chair, and back to the second hopper, where I found the mummy before-mentioned, and which had been placed there by Mr. Wilkins, for preservation in another cave.’
Indiana Cave.—In the southern part of Indiana there is a remarkable cave, which abounds in Epsom Salts, and which is thus described by Mr. Adams.—‘The hill in which it is situated, is about four hundred feet high, from the base to the most elevated point, and the prospect to the south-east, in a clear day, is exceedingly fine, commanding an extensive view of the hills and valleys bordering on Big Blue river. The top of the hill is covered principally with oak and chesnut. The side to the south-east is mantled with cedar. The entrance is about midway from the base to the summit, and the surface of the cave preserves in general about that elevation; although I must acknowledge this to be conjectural, as no experiments have been made with a view to ascertain the fact. It is probably owing to this middle situation of the cave, that it is much drier than is common.
‘After entering the cave by an aperture twelve or fifteen feet wide, and in height, in one place, three or four feet, you descend with easy and gradual steps into a large and spacious room, which continues about a quarter of a mile pretty near the same in appearance, varying in height from eight to thirty feet, and in breadth from ten to twenty. In this distance the roof is in some places arched, in others a plane, and in one place, particularly, it resembles an inside view of the roof of a house. At the distance above-named the cave forks, but the right hand fork soon terminates, while the left rises by a flight of rocky stairs nearly ten feet high, into another story, and pursues a course at this place nearly south-east. Here the roof commences a regular arch, the height of which from the floor varies from five to eight feet, and the width of the cave from six to twelve feet—which continues to what is called the Creeping Place, from the circumstance of having to crawl ten or twelve feet into the next large room. From this place to the Pillar, a distance of about one mile and a quarter, the visitor finds an alternate succession of large and small rooms variously decorated; sometimes mounting elevated points by gradual or difficult ascents, and again descending as far below; sometimes travelling on a pavement, or climbing over huge piles of rocks, detached from the roof by some convulsion of nature, and thus continues his route until he arrives at the Pillar.
‘The aspect of this large and stately white column, as it heaves in sight from the dim reflection of the torches, is grand and impressive. Visitors have seldom pushed their inquiries further than two hundred or three hundred yards beyond this pillar. This column is about fifteen feet in diameter, from twenty to thirty feet in height, and regularly reeded from the top to the bottom. In the vicinity of this spot are some inferior pillars of the same appearance and texture.
‘I have thus given you an imperfect sketch of the mechanical structure and appearance of the cave. It only remains to mention its productions.
‘The first in importance is sulphate of magnesia, or Epsom salts, which, as has been before remarked, abounds throughout this cave in almost its whole extent, and which, I believe, has no parallel in the history of that article. This neutral salt is found in a great variety of forms, and in many different stages of formation, sometimes in lumps, varying from one to ten pounds in weight. The earth exhibits a shining appearance, from the numerous particles interspersed through the huge piles of dirt collected in different parts of the cave. The foregoing remark applies with truth, not only to the surface, but to three feet below it. This is the greatest distance hitherto examined. The walls are covered in different places with the same article, and reproduction goes on rapidly. With a view to ascertain this fact, I removed from a particular place every vestige of the salt, and in four or five weeks the place was covered with small needle-shaped crystals, exhibiting the appearance of frost.
‘The quality of the salt in this cave is inferior to none, and, when it takes its proper stand in regular and domestic practice, must be of national utility. With respect to the resources of this cave, I will venture to say that every competent judge must pronounce them inexhaustible. The worst earth that has been tried will yield four pounds of salt to the bushel, and the best from twenty to twenty-five pounds.
‘The next production is the nitrate of lime, or saltpetre earth. There are vast quantities of this earth, and equal in strength to any that I have ever seen; and when potassium can be more conveniently obtained than at present, the manufacture of saltpetre must be a lucrative pursuit. There are also large quantities of the nitrate of allumina or nitrate of argyl, which will yield as much nitrate of potassium or saltpetre, in proportion to the quantities of earth, as the nitrate of lime.
‘The three articles above enumerated are first in quantity and importance; but there are several others, which deserve notice as subjects of philosophical curiosity. The sulphate of lime, or plaster of Paris, is to be seen variously formed; ponderous, crystallized, and impalpable, or soft, light, and rather spongy. Vestiges of the sulphate of iron, are also to be seen in one or two places. Small specimens of the carbonate, and also the nitrate of magnesia, have been found. The rocks in the cave principally consist of carbonate of lime, or common limestone.
‘I had almost forgotten to state, that near the forks of the cave are two specimens of painting, probably of Indian origin. The one appears to be a savage, with something like a bow in his hand, and furnishes the hint that it was done when that instrument of death was in use. The other is so much defaced, that it is impossible
