All that the youth could do was to attempt to follow the route that Fred had taken when he set out to place himself on the other side of the game. It was guesswork to trace his footsteps, but the elder youth made the effort. When he had progressed half the distance, however, he paused, convinced that his labor was utterly useless. He called to Fred, repeated their familiar signals and fired several charges in air, with no more response than at first. "He has been either killed or carried off by a party of Indians," was the conclusion that forced itself upon him. And with this conviction came the certainty that it was out of the power of Jack Dudley to do anything for his friend. He might tramp back and forth for nights and days, but with no success, for Fred Greenwood was gone--whither? Had Jack been skilled in woodcraft, possibly he might have discovered some signs along the valley that would have enlightened him, but he was untrained in the ways of red men and was not equal to the task. A dog that knew how to track a person would have been of immeasurable value, but such a canine was not to be had. One memory clung tormentingly to the searcher. It was the demoniac face of Motoza, the Sioux, when Fred Greenwood compelled him to return the Winchester of Jack. There could be but one interpretation of that expression, and it boded the worst for the missing youth. "Motoza feels no affection for me, but his hatred of Fred is so intense that he is bent on revenging himself; yet I did not think he would strike so soon." The afternoon was drawing to a close, and Jack was fully two miles from camp. If he wished to reach their rendezvous before night he had no time to waste. The problem was now in the shape that Hank Hazletine's help was indispensable. If anyone could assist Fred Greenwood, the guide was the man. "He promised to meet us this evening, and if I wait I shall lose my way." Accordingly the lad faced in the direction of the plateau and pressed forward with energy. In his haste he kept the former landmarks in view, and his previous experience had given him a certain familiarity with the region which prevented his going astray. Once more he leaped the canyon, without pausing longer than to glance into its depths as he swung over it. He saw nothing of the bulky carcass of the grizzly bear that had fallen a victim to the marksmanship of himself and friend, and just as night was shutting in he reached the edge of the small plateau where the ponies were contentedly grazing. In one respect better fortune than he anticipated awaited him. Instead of being compelled to pass the intolerable hours in waiting for the coming of the guide, he saw he had already reached the spot. A fire was burning at the mouth of the cavern, and the sinewy figure of the veteran was observed as he moved to and fro before it. Detecting the approach of Jack, he stood erect and silently watched him as he drew near.
