Presently, Leonard, who had fallen into one of his daydreams, woke up with a slight start and exclaimed,

“What a paradise!”

Jack smiled, and said, “I wonder whether it is a paradise without a serpent, as it is without an Eve? But your dreams, Leonard, if I remember, were mixed up with a comely damsel; and there is none here. I fear we shall have to regard her as the part that goes by contraries, as they say.”

Leonard looked hard at him, and there was evident disappointment in his glance and tone when he asked,

“Do you then think this place is uninhabited?”

“I do,” was the reply. “And I will tell you why. That stone that closed the entrance from the forest was placed there by some one, no doubt, and by some one inside. Yes; but how long ago? A very long time! Hundreds of years, I should say. It has taken quite that time for that stream of water to hollow out the little channel in the rocky side of the cave and play upon the cement until it has become loosened. The wood outside tells the same tale. It must be hundreds of years since any human beings made their way to and fro through the wood, to or from this place. Once there were many people here; and they were not ordinary people either, I can tell you. Not Indians, I mean, for instance. They were clever workers in stone. That ‘window,’ as I call it, through which we came in, is artificial.”

Elwood gave an exclamation of surprise.

“Yes; I noticed it, though you did not. I have little doubt that Monella noticed it too. The cavern was formerly all open, or, at least, it had a large opening, and I am almost certain its floor was originally level with the ground outside. If so, the present floor is artificial, and there are probably vaults beneath. Outside, the stonework is so artfully done that you see no trace of it; it appears to be all solid rock; but inside I saw distinctly traces of the joints. Then, look at these archways, at the one we are now sitting under! They have been worked upon too—to enlarge them, probably; to give more head-room when the floor was made higher. See! here are marks of the chisel!” And Templemore got up and pointed to many places where the marks left by the tool were clearly to be seen.

“Well,” said Elwood, “I suppose we shall solve the problem and set all doubts at rest before many days are over. For my part I am in a curious state of mind about it—half impatient, half the reverse. If it is to turn out as you say, I am in no hurry to terminate the uncertainty. This strange spot, the fact that we are really, at last, inside the wonderful mountain—these things open such a vista of marvellous possibilities that I—it seems to me—I would rather, you know——”

“Oh, yes, I know, you old dreamer,” Jack exclaimed, laughing. “You would rather wait and have time to dream on for a while than have your dreams rudely dispelled by hard facts. Now suppose we go and take a look round in the shade over there. We need not go out of sight of this entrance; so that Monella will find us immediately he returns.”
