They tore on, away from the noise of the flames, of the falling timber and the shouted commands, around the haystacks so close to the barbed-wire fence that the barbs cut his boot, off by the back of the quarters, and then upon the road that led from the reservation. If the pony could be kept on that road, there was small danger from dog holes. He would run himself out in time. The length of time was what was uncertain, however. A cow-pony can go a good many hours at a stretch. Cairness sat more erect, and settled down to wait. The motion was so swift that he hardly felt it. He turned his head and looked back at the flaming corrals, and, remembering the dead animals, wondered who had hamstrung them. Then he peered forward again the little way he could see along the road, and began to make out that there was some one ahead of him. Whoever it was scurrying ahead there, bent almost double in his speed, was the one who had hamstrung the mules and horses, and who had set fire to the corrals. The pony was rather more under control now. It could be guided by the halter shank. The man, still running, dodged from the road and started across country. Cairness wheeled and followed him. It was open ground, with not so much as a scrub oak or a rock in sight. The thick darkness offered the only chance of escape. But Cairness had chased yearlings in nights as black, and had brought them back to the herd. Down by the creek where the trees were thick, there would have been a good chance for escape, almost a certainty indeed, but there was little here. The man dodged again. It was just to that very thing that the pony had been trained. Habit got the better of stampede with it. It, too, dodged sharply. Cairness leaned far over and made a grab, but the first time he missed. The second he caught the neckerchief and held it, dragging the man, who resisted with all his giant strength, digging his toes into the ground as they tore along. And he was heavy. Cairness had no stirrup or pommel to trust to. He saw that it was a case of falling or of leaving go, and he decided to fall. The man would go underneath anyway. The man did go underneath and bravely offered resistance. Cairness had the twofold strength of his wiry build and of his bull-dog race. But Lawton--he knew it was Lawton now--would have been stronger yet, save that the three weeks' spree had told, and he was breathless. Cairness sat across him and held a revolver to his mouth. The life of the plains teaches agility of various sorts, but chiefly in the matter of drawing a six-shooter. "You fired the corrals," Cairness gasped. The fall had knocked the breath from his body. The under dog did not answer. "And you hamstrung those horses." No answer still. "Why did you do it?" No answer. "I'll break your jaws if you don't open them." The jaws opened forthwith, but no sound came, and Lawton struggled feebly.
