Seeing his mistake, Warren tried to right matters by a less abrupt approach. He dropped to a slow walk, holding out his hand and uttering soothing words. Had he done this at the beginning, he would have had no trouble in capturing any horse he desired, but the animals identified him as a stranger, and continued shy. The finest, which he had sought first to catch, closely watched him as he slowly approached, but at the very moment the heart of the youth was beating high with hope, he swung his head around and trotted beyond reach. Warren turned his attention to the one that was nearest, and by a sudden dash aimed to catch his halter, one end of which was dangling in the snow. As he stooped to grasp the thong, it was whisked from under his hand, and the pony galloped beyond his reach. The bitter disappointment made Warren desperate. He had undertaken an impossible task. He might succeed had more time been at his command, but the Sioux were liable to appear any minute. It would not do for him to be caught in this situation. He must abandon the attempt and get back among the trees and rocks, where there remained the bare possibility of eluding the red men. "What the mischief has become of Jack?" he muttered, facing about and breaking into a lope for the ridge. "If he were only in sight, he would come to me at once. Hello! just what I feared!" At that juncture he detected something moving among the trees. It was not clearly seen, but not doubting that the Sioux were coming, he broke into a run for cover, not daring to risk a shot until partial shelter was secured. In his affright he did not dare glance to the left even, and held his breath in thrilling expectancy, certain that with every leap he took he would be greeted by a volley, or that the Sioux would throw themselves across his track to shut off all chance of escape. That they did not do so was not only unaccountable to him, but gave him the hope that possibly he might still elude them. Bending his head, he ran with might and main. The distance was not great, but it seemed tenfold greater than it was, and a slip of the foot, which came near bringing him to his knees, filled his heart with despair and made him certain that he would soon join Tim Brophy. He heard his pursuers at his heels. Despite his own fleetness, they were outspeeding him. Nothing could save him from being overtaken before reaching the ridge. Suddenly a peculiarity in the sound made by those at his rear caused him abruptly to halt and look around. Then, to his unbounded delight and amazement, he recognized his own pony, Jack, striving hard to keep him company. CHAPTER XXV. THE PRAIRIE DUEL. Warren Starr could have hugged his pony in his transport of delight. Until a moment before he was sure several of the Sioux were upon him; when, wheeling about, he was confronted by Jack, whom he had been desirous of meeting above every other person or animal in the world.
