"I've chosen him, and I'm going to bag him, whatever happens," thought our hero, as he raced along. "I'll follow in after the beast."

Pressing his horse with both knees, and urging him forward with voice and spur, he managed to wedge himself in the last line of moving buffalo. Another effort and he passed right through it, and was almost within shot of the animal he wanted. Then he heard a sharp report on his right, followed by a shout, and, turning, saw Steve riding hard towards him.

"Yer've got to be careful in thar," shouted the hunter. "Mind their horns, and jest see that when he falls the others don't come tumbling on ter yer. Now, let him have it."

Steve was within a few feet of Jack now, for the hunter felt anxious for the safety of his young friend.

"I never seed a new 'un with more grit," he was saying to himself. "The most of 'em would be content to ride up behind, and fire from a little distance. But Carrots ain't like that. I've noticed he's a way of doin' a thing proper or not at all. He's bound on making a point-blank shot."

That, in fact, was Jack's intention, and, careless of the tossing heads about him, of the horns turning this way and that, and of the angry bellows, he pressed his horse still more forward, till he was right up against the beast he had selected. And there, jammed in the press, and going hard all the while, our hero stood up in his stirrups, watched for the right moment, and fired his weapon, aiming just behind the moving shoulder.

"Pull out!" shouted Steve, "Pull out or they'll carry yer along."

To retire from the position he had taken up was not an easy task, as Jack soon found; for behind him a solid wall of buffalo swung along, while the animal he had fired at still galloped forward as if it had received no wound. It seemed, indeed, as if our hero had failed. But he was not the lad to give in easily. Food was wanted for the camp, and this was the very first opportunity he had had of showing his prowess. Once more he spurred up beside the beast and sent a second bullet crashing into his body. And then there was a sudden change in the situation. The buffalo dropped like a log, while the animal immediately behind tripped, fell on his nose, and in doing so knocked the legs of Jack's mount from under him. In an instant there was a scene of dire confusion. Jack went flying far ahead, over the ears of his horse, while Steve, who was riding just behind him by then, came a terrible cropper. Clouds of dust were thrown into the air, and dimly seen through it were struggling beasts, feet lashing here and there, and frightened eyes. Never had Jack heard such a bellowing. It seemed as if all the buffalo in that country were round him, and then, as suddenly, they were gone. The beasts who had fallen got to their feet and charged madly by him, leaving him alone with the one he had shot, stretched just a foot away from it, while farther behind was his horse, looking at him, as if the poor beast still wondered what had happened. As for Steve, he lay very still, one boot remaining in his stirrup, while his well-trained beast stood close beside him, grazing, as if buffalo had never existed, and as if such a thing as a catastrophe had never occurred.

Jack clambered to his feet and ran to Steve, to find him conscious, and lying with eyes wide open.

"Jest lift my foot out of the stirrup," he said cheerfully, but in a voice little above a whisper. "We was goin' fast, I guess? and I wasn't lookin' for a fall. Reckon my back's badly shook, 'cos I ain't got no power over my legs. Pain? No. I ain't any, but it's queer fer me to be lying here unable ter move."
