About 25 yards north of Nellie's Grotto is "The Vestry," a cavern about 12 feet high, 8 feet wide, and 20 feet in length. It is called The Vestry, because of its propinquity to some very fine cathedral-like architecture, and not because any minister requires it to robe himself in, or because it is used for the meetings of any parochial assembly. This Vestry runs east and west, and there is here a large area of unexplored caves. Indeed, it may be said that there are in almost every part of the mountain openings which indicate the possibility of the existence of new and lovely caverns. It is also probable that in process of time it will be found that all the principal chambers are connected by passages which by a little enlargement may make intercavernous communication complete between all the best known caves. That this is likely may be gathered from an incident which occurred a few months ago. There were then at the Cave House four black cats, slightly marked with white. On being petted, the playful animals would not only purr their thanks, but also follow like dogs. One day the most venturesome of them went with a party into the Lucas Cave, and travelled with them a considerable distance before it was missed, and then it was thought that it had returned to the daylight. In the evening, however, it was not in its accustomed place on the hearthrug, and about the middle of the following day it was discovered in the Imperial Cave on the other side of the Grand Arch! The attention of the party was attracted by the doleful cries of the animal, which had by that time realised the fact that it had lost itself in a dangerous place. Some doubt might have existed as to the identity of the cat found in the Imperial with that lost in the Lucas Cave, had it not been that with the party that took it in were two boys, who had carried it now and then, and permitted its extremities once or twice to come in contact with their lighted tapers. They were able to identify it by "the drips of sperm on its back, its burnt whisker, and the singe on the tip of its tail!" Thus a very interesting fact was established which but for the accidental brandings would have been doubtful. The visitor returns to the Fairies' Bower and the Grand Stalactites junction; and about 20 yards north-west from the junction he arrives at the Crystal Palace, which is fenced in by wire-netting in order to protect its marvellous grandeur from that class of sightseers who appear to be unable to look at anything except they can place their unwashed paws upon it--in which case impressions are mutual.
