ornamentation, and having minute stalactites projecting from the sides. All about it are nodules of delicate fretwork, as lovely as the coral of the ancient sea out of which this mountain was made millions of years ago. On the apex is a gracefully-tapered cone; and hard by is a small stalagmite covered with prickles as sharply defined as those of the echinus. All around are limestone pictures of surpassing loveliness. There is not much variety of colour, but the formation is infinite in its variety. It is intended to have the hideous and perilous-looking volcanic funnel previously mentioned guarded by wirework, which is necessary to ensure the complete safety of sightseers. If an unfortunate wight were to trip, he might fall a distance of about 70 feet, and be shot without ceremony into the Devil's Coach House. One remarkable stalagmite in the vicinity of this infernal shaft is shaped like a hat, and another is like a gigantic mushroom. The floor of the cave is thin, and when stamped upon vibrates in imitation of an earthquake wave. Stalactites in rich profusion depend from the roof, and here and there are clumps of bats, clinging together like little swarms of bees. The stalactites are tipped with drops of lime-water clear as crystal at the lowest point, and becoming gradually opaque. It is also noticeable that while the drops at the ends of the stalactites appear to be perfectly still globular bodies, their molecules seem to be in perpetual motion. The opaque part of the drops thickens until it resembles sperm, and then the gradation is almost imperceptible until it unites with the solid formation. All around are curiously-shaped drives, one of which has been explored until it communicates with the Imperial Cave. It is not an inviting entry, for it is low and narrow, and has sharp stalactites on the roof. The floor is covered with very fine dust, about the eighth of an inch thick, which, however, seems not to rise, and when struck with a hammer the sound is like a blow struck upon a carpet, and the dull thud reverberates in the caverns below.
