"This is my bed, and if you should be tired when we get back from our tour through the caverns, or at any time, you can lie down here and sleep in perfect safety," said the girl.
"I thank you," answered Sybil, as they passed out of that division into another.
It was as the girl had told her, a net-work or cell-work of caverns, occupying, as far as it had been explored, several acres under the mountain. All these caverns bore a natural resemblance to each other. All had their roofs and walls incrusted with pearly spars and hung with glittering stalactites, and their floors covered with living moss; and all were connected by narrow passages, with the walls lapping past each other.
But some of these caverns were large, and lighted by crevices in the roof, and others were small and dark. Some of the passages between them were also wide and free, and some narrow and impassable. And in some black inaccessible holes was heard the fearful sound of subterranean waters. In one of the larger divisions of the cavern there were boxes and bales of merchandise, and silver plate and jewels; in another there was the complicated machinery of an underground distillery; and in still another was a collection of burglars' tools, counterfeiters' instruments, and firearms.
"I show you all! I do not fear to do so! You will never betray us, even if you have a chance; but you will never have a chance," said the guide.
"What! You would not keep me here for ever?"
"No; for we shall not stay for ever. Be comforted, lady! No harm is intended you," said the girl, as, having shown her guest all that was to be seen of the caverns, she conducted her back to the bedroom.
"I am very much surprised at all that I have seen," said Sybil. "I had no idea that there was a cave of such extent and beauty so near our home."
"I believe," answered the girl, "that there are many caves in the mountains, as there are many isles in the ocean, that have never been discovered."
Sybil looked up in surprise. "You call yourself the companion of thieves, yet you talk like a person of intelligence and refinement," she said.
