Jack Dudley suddenly gripped the arm of his friend and drew him back from the boulder on which they had been sitting. Fred nearly lost his balance, and did not know what to make of the proceeding until both checked themselves at a safe distance and cautiously peeped forth. Then the cause of Jack's excitement became apparent. From the pines on the other side of the stream, and near the middle of the depressed portion, three Indians stepped into view. The first anxiety of the youths was to learn whether Motoza was one of them; but he was not. All were strangers. They were dressed much the same as the vagrant Sioux, and, like him, their faces were painted, and their coarse black hair dangled loosely about their shoulders. They were armed with rifles; but two of the weapons seemed to be the long, old-fashioned muzzle-loaders, while the third carried a Winchester. Although they emerged from the pines in Indian file, they spread apart and walked beside one another to the edge of the broad stream, where they stopped, as if that were the end of their journey. Their gestures showed they were talking energetically, though of course not the slightest murmur reached the youths, who took care to screen themselves from view while cautiously peeping forth. Even after the warning words of their guide they felt no special alarm, for they believed the red men were from the reservation near by, and would not harm any one. If they attempted it, Jack and Fred felt they had the advantage of position, sheltered behind the rocks, far above their enemies, down upon whom they could fire with their Winchesters, should the necessity arise. It was quite certain that the three belonged to one of the hunting parties whose signal-smoke the boys had seen earlier in the day. Their action was curious. They did not look up the bank, so that the boys might have been more careless without being discovered; but it was apparent that two of them were arguing with the third, who was more excited than either of his companions. Finally he turned away and made as if to pass up the canyon, after the manner of Hank Hazletine. He leaped out upon one of the rocks, then bounded as lightly to another, and then to a third, which took him within the canyon. The others watched him without protest or action. Evidently the Indian who had started off so hurriedly was more impulsive than his companions, for after his third leap he remained standing on the rock; and, although it would have been easy for him to spring to the next leading up the canyon, he refrained from doing do. Instead, he looked around, and then deliberately rejoined his friends, who showed no surprise over his reverse movement. They spoke only a few words to one another, when they moved back in Indian file toward the growth of pines, among which they passed from sight and were seen no more.
