The fellow, instead of approaching, merely stood and stared; his eyes bulging and his jaw dropped. And then another savage face appeared, and a third and fourth and fifth, craning their necks over the shoulders of their fellows whom they could not pass upon the narrow ledge. Each face was the picture of awe and fear, but for what reason I did not know, nor did I learn until ten years later. That there were still other braves behind those who regarded me was apparent from the fact that the leaders passed back whispered word to those behind them.

Suddenly a low but distinct moaning sound issued from the recesses of the cave behind me, and, as it reached the ears of the Indians, they turned and fled in terror, panic-stricken. So frantic were their efforts to escape from the unseen thing behind me that one of the braves was hurled headlong from the cliff to the rocks below. Their wild cries echoed in the canyon for a short time, and then all was still once more.
