All the cowboys hated Satan, and with good reason. More than one of them bore marks of the horse's sharp teeth, and all of them could tell stories of narrow escapes experienced while feeding him or otherwise going through duties that called them into the neighborhood of the beautiful but vicious animal.

He was pastured in lonely grandeur in a spacious corral, shunned by all, but apparently happy enough in spite of this. The three boys often watched him at a safe distance, and regretted that his evil temper made it impossible to be friendly with him. Satan often lost many a lump of sugar or delicious carrot that he would have gotten had he been of a more friendly nature, in this way resembling many humans who build up a wall of reserve or ill-temper about them, and so lose many of the good things of life.

Soon after the arrival of the boys at the ranch Mr. Melton decided to purchase another stallion, as the demand for good horses at that time was exceptionally great. Accordingly, one day another horse made his appearance in a corral adjacent to that in which Satan was kept. The new horse was a good-sized bay, but not quite as large as Satan, although a little younger. The two corrals were separated by a double fence, so that, while the two horses could get within a few feet of each other, they could never get close enough to fight.

From the very beginning they exhibited a mutual hatred, and it was evident that if they ever got within striking distance of each other there would be trouble. Everybody on the ranch was strictly enjoined to keep the gates between the corrals securely fastened, however, and there seemed no possibility of the two rivals meeting.

"But if they ever should," one of the men had remarked, "there'd be some scrap, take it from me. There's nothing in the world worse than a fight between two stallions."

"Why, are they so vicious about it?" Bert, who was standing near, had asked.

"Vicious!" exclaimed the cowboy, "why, vicious ain't no word for it, nohow. They're just devils let loose, that's all."

It was only a few days after this that, as the boys were seated around the table in the ranch house eating luncheon, in company with their host, one of the cowboys dashed into the room, breathless and red of face.

"Satan an' the bay are fightin'," he cried; "somebody must 'a' left the gates open an'——"

But Mr. Melton did not wait to hear any more. Leaping to his feet he dashed through the door in the direction of the corrals. The three comrades followed close on his heels. As they reached the open they could hear shouts and cries and the thudding of hoofs. Mr. Melton increased his pace, and in a few moments they had reached the scene of action.
