On that hard rock we lay for many weary hours. We had no food; but for that I would soon have been myself again, for, though my wounds were numerous, they were little more than scratches, with the exception of the gash on my shoulder. Weakened as I was by loss of blood, and lacking nourishment, I improved but slowly, and only the cold water kept the fever from me.

Twice Harry went out in search of food and of an exit from the cavern. The first time he was away for several hours, and returned exhausted and empty-handed and without having found any exit other than the one by which we had entered.

He had ventured through that far enough to see a group of Incas on watch at the other end. They had seen him and sprung after him, but he had returned without injury, and at the entrance into the cavern where we lay they had halted abruptly.

The second time he was gone out more than half an hour, and the instant I saw his face when he returned I knew what had happened.

But I was not in the best of humor; his terror appeared to me to be ridiculously childish, and I said so in no uncertain terms.

But he was too profoundly agitated to show any anger.

"You don't know, you don't know," was all he said in answer to me; then he added; "I can't stand this any longer. I tell you we've got to get out of here. You don't know how awful—"

"Yes," said Desiree, looking at me.

"But I can scarcely walk," I objected.

"True," said Harry. "I know. But we can help you. There must be another exit, and we'll start now."
