Jack sat there most of the afternoon, and from his chair trained his horse, and it proved as Hugh had said, that before supper time Pawnee knew that a blast on the whistle meant that he was to be offered a lump of sugar, which he was always ready to take. Jack was perfectly delighted with his success, and determined that he would keep up this education of the horse until it had been so thoroughly trained that it would seek him at the whistle wherever he might be. The interest that he felt in this lightened up the next two or three days wonderfully. Each day he hopped about on his crutch a little more easily, and at last he was able to put his injured foot to the ground without much pain. He worked with Pawnee down in the corral and out on the flat in front of the house, and at last he took the rope off the animal and turned it loose, letting it wander where it would, and when he found that he could call the loose horse from a distance of a quarter of a mile, and it came galloping or trotting toward him at the sound of the whistle, he felt that he had really accomplished a great feat. Hugh congratulated him heartily on his success. "I had a horse once," he said, "that I trained to do this, and there was lots of times when it was mighty handy to me. Most folks think that a horse is just a fool and don't know nothing; but it ain't so. A horse, if you treat it right, is a mighty knowledgeable critter, but most people don't know enough to see what there is in one, and think you can't get nothing out of it without you use a quirt, spurs, and maybe a club. Of course it's a mighty nervous animal, and it's always been used to being chased, and so it is scary, but there's lots of sense to a horse if you take it right." At length Jack's foot was well enough for him to ride; but his first two or three rides were close about the ranch and on old Grey, which could be trusted not to make any sudden movements, and so not to oblige Jack to use his lame foot, which, however, was recovering rapidly, the cold water treatment, which Hugh had insisted on giving it having proved very effective. During this period of his confinement, Jack had seen more of Shep, the ranch dog, than he ever had before. This was a big yellow shaggy shepherd dog, very affectionate and a very good watch dog, but rather a foolish, puppy-like beast, that was not especially popular with anyone. Hugh had said of him, "That dog there thinks he's a runner, and he thinks he's a fighter too, and he ain't neither one nor the other. He'll start off and chase an antelope or a jack rabbit, like he thought he was going to catch it without any trouble, but the things run off ahead of him, not a bit scared, and he just runs himself down and comes back with his tongue hanging out a yard, looking, and I expect feeling, like a fool. He ain't never caught nothing yet, and I don't expect he ever will catch anything."
