"It may be—perhaps I can go with you," I suggested. But he would not hear of it, and set out again alone in the opposite direction to that which he had taken previously.
In a few minutes he returned, reporting no better success than before. On that side, he said, the wall of the cavern was quite close. There was no sign anywhere of water; but to the left there were several narrow lanes leading at angles whose sides were nearly parallel to each other, and some distance to the right there was a broad and clear passage sloping downward directly away from the cavern.
"Is the passage straight?" I asked, struck with a sudden idea. "Could you see far within?"
"A hundred feet or so," was the answer. "Why? Shall we follow it? Can you walk?"
"I think so," I answered. "At any rate, I must find some water soon or quit the game. But that isn't why I asked. Perhaps it explains the sudden disappearance of the Incas. They knew they couldn't follow us through that narrow crevice; what if they have made for the passage?"
Harry grumbled that we had enough trouble without trying to borrow more.
We decided to wait a little longer before starting out from the cavern; Harry helped me to my feet to give them a trial, and though I was able to stand it was only by a tremendous effort and exertion of the will.
"Not yet," I murmured between clenched teeth, and again Desiree sat on the hard rock and supported my head and shoulders in her arms, despite my earnest remonstrances. Harry stood before us, leaning on his spear.
Soon he left us again, departing in the direction of the crevice by which we had entered; I detected his uneasiness in the tone with which he directed us to keep a lookout around in every direction.
"We could move to the wall," I had suggested; but he shook his head, saying that where we were we at least had room to turn.
