Denver was a beautiful bay stallion, the pride and terror of the ranch. He was noted for his speed and his vindictive hatred of the more plebeian horses, scarcely one of which but had, at some time, felt his teeth in their flesh--and he was hated and feared by them all. He stopped at the place where the trail forked, tossed his crinkly mane triumphantly and looked back. Freedom was sweet to him--sweet as it was rare. His world was a roomy box stall with a small, high corral adjoining it for exercise, with an occasional day in the little pasture as a great treat. Two miles was a long, long way from home, it seemed to him. He watched the hill behind a moment, threw up his head and trotted off up the trail to Denson's. Chip, galloping madly, caught a glimpse of the fugitive a mile away, set his teeth together, and swung Blazes sharply off the trail into a bypath which intersected the road further on. He hoped the Little Doctor was safe at Denson's, but at that very moment he saw her ride slowly over a distant ridge. Now there was a race; Denver, cantering gleefully down the trail, Chip spurring desperately across the prairie. The Little Doctor had disappeared into a hollow with Concho pacing slowly, half asleep, the reins drooping low on his neck. The Little Doctor loved to dream along the road, and Concho had learned to do likewise--and to enjoy it very much. At the crest of the next hill she looked up, saw herself the apex of a rapidly shortening triangle, and grasped instantly the situation; she had peeped admiringly and fearsomely between the stout rails of the little, round corral too often not to know Denver when she saw him, and in a panic turned from the trail toward Chip. Concho was rudely awakened by a stinging blow from her whip--a blow which filled him with astonishment and reproach. He laid back his ears and galloped angrily--not in the path--the Little Doctor was too frightened for that--but straight as a hawk would fly. Denver, marking Concho for his prey and not to be easily cheated, turned and followed. Chip swore inwardly and kept straight ahead, leaving the path himself to do so. He knew a deep washout lay now between himself and the Little Doctor, and his only hope was to get within speaking distance before she was overtaken. Concho fled to the very brink of the washout and stopped so suddenly that his forefeet plowed a furrow in the grass, and the Little Doctor came near going clean over his head. She recovered her balance, and cast a frightened glance over her shoulder; Denver was rushing down upon them like an express train. “Get off--your--H-O-R-S-E!” shouted Chip, making a trumpet of his hands. “Fight Denver off--with--your whip!”
