“How do you know this?” asked Tanar.
“I discovered it once when I was hunting. I came upon a strange tunnel leading from that along which I was making my way to the upper world. I followed it to see where it led and I came at last to the opening in the ceiling of this cavern, from whence one may see all that takes place below without being himself seen. When I was brought here as a prisoner I recognized the spot immediately. That is how I know that one may escape if he has proper help.”
“Explain,” said Tanar.
“The wall beneath the opening is, as I have discovered, inclined backward from the floor to a considerable height and so rough that it can easily be scaled to a little ledge beneath the opening in the ceiling, but just so far beneath that one may not reach it unaided. If, however, I could lift you into the opening you could, in turn, reach down and help me up.”
“But how may we hope to climb the wall without being seen by the guards?” demanded Tanar.
“That is the only chance of capture that we shall have to take,” replied Mow. “It is very dark there and if we wait until another prisoner is brought and their attention is diverted we may be able to succeed in reaching the opening in the ceiling before we are discovered, and once there they cannot capture us.”
Tanar discussed the plan with Jude, who was so elated at the prospect of escape that he almost revealed a suggestion of happiness.
And now commenced an interminable wait for the moment when a new prisoner might be brought into the cavern. The three conspirators made it a practice to spend most of their time in the shadows at the far end of the cavern so that the guards might become accustomed to seeing them there, and as no one other than themselves was aware of the opening in the ceiling at this point no suspicions were aroused, as the spot where they elected to be was at the opposite end of the cavern from the entrance, which was, in so far as the guards knew, the only opening into the cavern.
Tanar, Jude and Mow ate and slept several times until it began to appear that no more prisoners ever would be brought to the cavern; but if no prisoners came, news trickled in and one item filled them with such alarm that they determined to risk all upon the hazard of a bold dash for freedom.
Some Coripies coming to relieve a part of the guard reported that it had been with difficulty that Xax had been able to suppress an uprising among his infuriated tribesmen, many of whom had conceived the conviction that Xax was saving all of the prisoners for himself.
