In the end "Jack," as Harold called the roan, walked up to his master and rubbed his nose against his shoulder. Harold then stripped away the bridle and pad at once, and when he put them on next day Jack winced, but did not plunge, and Harold mounted him. A day or two later the colt worked under the saddle like an old horse. Thereafter it was a matter of making him a horse of finished education. He was taught not to trot, but to go directly from the walk to the "lope." He acquired a swift walk and a sort of running trot--that is, he trotted behind and rose in front with a wolflike action of the fore feet. He was guided by the touch of the rein on the neck or by the pressure of his rider's knee on his shoulder. He was taught to stand without hitching and to allow his rider to mount on either side. This was a trick which Harold learned of a man who had been with the Indians. "You see," he said, "an Injun can't afford to have a horse that will only let him climb on from the nigh side, he has to get there in a hurry sometimes, and any side at all will do him." It was well that Jack was trained early, for as they drew out on the open prairie and the feed became better the horses and cattle were less easy to drive. Each day the interest grew. The land became wilder and the sky brighter. The grass came on swiftly, and crocuses and dandelions broke from the sod on the sunny side of smooth hills. The cranes, with their splendid challenging cries, swept in wide circles through the sky. Ducks and geese moved by in myriads, straight on, delaying not. Foxes barked on the hills at sunset, and the splendid chorus of the prairie chickens thickened day by day. It was magnificent, and Harold was happy. True, it was not all play. There were muddy roads to plod through and treacherous sloughs to cross. There were nights when camp had to be pitched in rain, and mornings when he was obliged to rise stiff and sore to find the cattle strayed away and everything wet and grimy. But the sunshine soon warmed his back and dried up the mud under his feet. Each day the way grew drier and the flowers more abundant. Each day signs of the wild life thickened. Antlers of elk, horns of the buffalo, crates of bones set around shallow water holes, and especially the ever-thickening game trails furrowing the hills filled the boy's heart with delight. This was the kind of life he wished to see. They were now beyond towns, and only occasionally small settlements relieved the houseless rolling plains. Soon the Missouri, that storied and muddy old stream, would offer itself to view.
