A chorus of fierce yells answered him, and the slow movement of the wild-looking array changed into a swift, pell-mell gallop. It had been a whoop of discovery. At no great distance from the knoll upon which Great Bear had sounded his war-cry a voice as shrill and as fierce, although not as powerful, replied to him with the battle-yell of the Lipans. In another instant, the wiry mustang which carried an Indian boy was springing away at his best pace eastward. Probably it was well for his rider that the race before him was to be run with a light weight. Red Wolf was all alone, but if Great Bear was hunting Lipans, they, on their part, were on the lookout for Comanches. Their cunning chief had read, as clearly as had Travis, the wrathful face of Great Bear. He had camped for one night in the comparatively secure vicinity of San Antonio. Shortly after he and his braves began their homeward ride that morning, he had given to his son and to several others orders which were accompanied by swift gesticulations that rendered many words needless. What he said to Red Wolf might have been translated,-- "We are to strike the chaparral on a due south line from the fort. Ride a mile to the west of our line of march. Keep your eye out for enemies. If you see any, get back to us full speed. Great Bear has sixty braves. Maybe more. We are only twenty. He would wipe us out." Away went Red Wolf. He was only a scout, but he was a youngster doing warrior duty, and he felt as if the fate of the whole band depended upon him. It was another big thing to add to his remarkable experiences of the day before,--a fort, guns, a grand cock-fight, and the heroes of the border,--white chiefs who were famous among all the tribes. More than all, and he said so as he rode onward, he had been spoken to by the Big Knife of the palefaces, and he had not only seen but had handled the "heap medicine knife" itself. He was now almost a brave, with a name given him by the hero, his father's friend, and he was burning all over with a fever to do something worthy of the change in his circumstances. He was well mounted, for he was the son of a chief, and there had been a drove of all sorts to select from. The mustang under him was a bright sorrel,--a real beauty, full of fire, and now and then showing that he possessed his full share of the high temper belonging to his half-wild pedigree. Mile after mile went by at an easy gait, and the watchful scout had seen nothing more dangerous than a rabbit or a deer. He was beginning to feel disappointed, as if his luck were leaving him. It was hard upon a fellow who was so tremendously ready for an adventure if none was to be had. He even grew less persistently busy with his eyes, and let his thoughts go back to the fort. "Heap big gun," he was remarking to himself. "Kill a heap. Shoot away off."
