A curious thing happened. Jack was looking in the direction named, when, with startling suddenness, an Indian shot into sight on the furthest rock, beyond which the canyon made a sweeping curve that shut off further view. His appearance was like the upleaping of a Jack-in-the-box at the touch of the spring, but the explanation was evident: he was making his way down the gorge from above, when his leap from one rock to another brought him thus abruptly into view. This was interesting of itself, but a still more interesting discovery came with the second glance at him. He was Motoza, the Sioux! It looked as if Hank Hazletine, with all his subtlety and woodcraft, had failed to do that which came of itself to Jack Dudley. The actions of the Sioux showed he was unusually careful about being seen as he emerged from the canyon into fuller view, for, after leaping to the rock which stood at the door of the gorge, he stood a minute, then leaned forward and peered around the sides as far as he could without losing his balance. He next stood erect and looked keenly across the pool, and apparently at the very spot where the boy lay hiding. "What a face!" muttered Jack; "I never saw one so ugly, with those daubs of paint; and his eyes shine just like that rattlesnake's we killed. It can't be he sees me," added the youth in alarm, as he cowered still lower; "one would think he could look through a stone." But nothing less than the Roentgen ray would have revealed the young man, who was stealthily watching the ferocious buck. The latter must have decided that the coast was clear, for with another bound he landed upon a rock quite a way from the opening of the canyon, and a second leap placed him on the shore where three of his race had been standing when discovered by Jack and Fred. Motoza did not linger, but moved with a very rapid stride across the open space, where he was in full view of anyone in the vicinity. "If I were sure you had done any harm to Fred," muttered Jack, never removing his eyes from the repellant countenance, "I believe I could treat you as we did the grizzly bear without a sting of conscience. The idea of your harming a hair of the head of Fred Greenwood, who showed you tenfold more mercy than you deserved--my gracious! he must have seen me." This involuntary exclamation was caused by the fact that the Sioux was following a bee-line for the spot where Jack lay. Believing a meeting inevitable, the youth placed his hand on his revolver, the preferable weapon in the event of coming to close quarters. But at the last moment Motoza turned to the left and passed among the rocks within a couple of paces of the youth, who held his breath until he was gone.
