"Not much!" answered Phil. "Just wait till my horse gets his muscles limbered up a bit!" And then he urged his animal to a better gait, and slowly but surely crawled up closer to Roger. Dave said but little, for he was paying all his attention to Hero. He had studied horses from childhood, and he thought he saw in the steed he rode better staying qualities than in either of the other animals. He kept on directly behind his chums, but made no effort for the first half mile to pass them. "How far do we race?" cried the senator's son, presently. "To the patch of woods," answered Dave, indicating a growth about a mile distant. "All right--and--good-by to you!" returned Roger, merrily. "Dave, you aren't in it a little bit!" added Phil. And he sped after the senator's son, leaving Dave a full fifty yards in the rear. Dave saw that Hero was gradually warming up to his task. He clucked softly, and the little black horse pricked up his ears and increased his gait. Then Dave clucked again--he had heard Todd do this--and Hero went a little faster. On went the three boys, the fresh air of the plains and the mountains filling their lungs and causing their eyes to snap with pure delight. At that moment each of them felt as if he hadn't a care in the world. Phil and Roger were now neck-and-neck, with not quite half a mile of the race still to cover. Sixty yards behind was Dave. Still further to the rear was Sid Todd, now urging his horse forward, that he might see the finish of the contest. "Now, then, my little beauty, go!" cried Dave to his horse, and he clucked several times to Hero, and dug his heels into the steed's ribs. He had not miscalculated, and Hero responded instantly. Up he went into the air, and when he came down his ears were laid far back, and forward he shot like an arrow from a bow. Dave kept him to it, and gradually he ranged up between the others. "Hi, get back there!" yelled Roger, who was now slightly in advance. "You can beat Phil, but you can't beat me!" "Not much! He's not going to beat me!" put in the shipowner's son, and he urged his horse to do better. But this was impossible, and, inch by inch, Dave overtook him, and went to the front. It now seemed to be a race between Hero and the brown horse that the senator's son rode. Roger's mount was still in fine condition, but it must be confessed that the senator's son did not know exactly how to race him to the best advantage. He sawed a little on the reins, thus worrying the animal, and causing him to lose his gait. Then, with a bound, Dave came up, and the pair were neck-and-neck for the finish. "Go! go!" yelled Phil. "May the best horse win!" "Whoopee!" came unexpectedly from Sid Todd, and, grabbing his pistol from the holster, he sent three shots into the air, just to add to the excitement.
