Ned was not yet fairly out from the tree, when he paused, for his ear detected something alarming. It was the soft splash of water, such as is made by a person who is carefully wading along, and it sounded fearfully near to where he was. He assumed at once, because of the peculiar sound, that it must be caused by some one who was hunting for him, and no one could be hunting for him except some of the Apaches from whom he fled. If any doubt remained in his mind, it was removed a moment later, when he heard a whistle from the same quarter whence came the sound of the wading. The signal was instantly responded to in the same manner by some one upon shore. "They're Indians," he said. "They know that I must be somewhere in this neighborhood and they've made up their minds to search until they find me." For two or three minutes all was as still as the tomb. It seemed as if the redskins were listening, in the hope of learning something of the fugitive through their sense of hearing when their eyes had failed them so long. If such were the case, they were disappointed, for the boy crouching in the gnarled tree would have suspended his very breathing, had it been in his power to do so, lest he should betray himself. When the splashing noise was heard again, it sounded almost beneath him, and, yielding to a most dangerous curiosity, which, however, he could not restrain, he reached one hand into the foliage, drew it aside and looked down. Not more than twenty feet distant he saw the figure of Lone Wolf, the Apache chief! He stood in the water up to his knees, and, at the moment the fugitive looked, had passed a short distance beyond the tree, so that his back only was visible. Had it been a few minutes sooner, the warrior would have assuredly seen the white, scared face that peered upon him from among the leaves. But, as it was, he was all unconscious of the fact that he was so near the prize for which he and several of his best warriors had been searching for hours. Two of them had paused beneath the tree and carefully examined the branches without discerning the hiding place, and they were now moving forward again, carefully examining everything on each side of the stream where it seemed possible for a cat, even, to conceal itself. Lone Wolf would have given his right arm, almost, rather than have his prisoner elude him. He had been completely deceived by that little artifice of lameness, and it was not until a full half hour after Ned's disappearance that he began to suspect that something was amiss. The trail was taken up at once and followed without trouble to where it entered the water. Here the real task began, for the hardness of the bed of the creek prevented them from tracing the footsteps where the clearness of the current would have enabled them to do so, had the circumstances been otherwise.
