He did not have to wait long. He had not thought to do so. How full the woods were of blood-scenting and man-eating things none knew better than he. His ear, keen and trained, caught the patter of a distant approach. "Wolves," he said to himself at first, and then "Hyenas," for the step was puzzling. He was perplexed. The step was regular, and it was not in the forest on either side, but was coming up the path. A terror came upon him and he had crawled deeper into the shades, when he noted that the steps first ceased, and then that they wandered searchingly and uncertainly. Then, loud and strong, rang out a voice, calling his name, and it was the voice of Oak! He could not answer for a moment, and then he cried out gladly. Oak had, in the forward-rushing group, seen Ab's hurt and fall, but had thought it a trifling matter, since no outcry came from those behind, and so had kept his course away and ahead with the rest. But finally he had noted the absence of Ab and had questioned, and then--first telling some of his immediate companions that they were to lag and wait for him--had started back upon a run to reach the place where he had last seen his friend. It was easy now to arrange wet leaves about Ab's crippling, but little more than temporary, wound. The two, one leaning upon the other and hobbling painfully, and each with weapons in hand, contrived, at last, to reach Oak's lingering and grumbling contingent. Ab was helped along by two instead of one then, and the rest was easy. When the pathway leading to home was reached, Oak accompanied his friend, and the two passed the night together. Ab, once on his own bed, with Oak couched beside him, was surprised to find, not merely that his physical pain was going, but that the greater one was gone. The weight and burning had left his breast and he was no longer angry at Oak. He thought blindly but directly toward conclusions. He had almost wanted to kill Oak, all because each saw the charm of and wanted the possession of a slender, beautiful creature of their kind. Then something dangerous had happened to him, and this same Oak, his friend, the man he had wished to kill, had come back and saved his life. The sense which we call gratitude, and which is not unmingled with what we call honor, came to this young cave man then. He thought of many things, worried and wakeful as he was, and perhaps made more acute of perception by the slight, exciting fever of his wound.
