At the end of another hour Jack Belllounds came out of the house, gazed around him, and then stalked to the barn where he kept his horses. For a little while he was not in sight; then he reappeared, mounted on a white horse, and he rode into the pasture, and across that to the hay-field, and along the edge of this to the slope of the hill. Here he climbed to a small clump of aspens. This grove was not so far from Wilson Moore's cabin; in fact, it marked the boundary-line between the rancher's range and the acres that Moore had acquired. Jack vanished from sight here, but not before Wade had made sure he was dismounting. "Reckon he kept to that grassy ground for a reason of his own--and plainer to me than any tracks," soliloquized Wade, as he strained his eyes. At length Belllounds came out of the grove, and led his horse round to where Wade knew there was a trail leading to and from Moore's cabin. At this point Jack mounted and rode west. Contrary to his usual custom, which was to ride hard and fast, he trotted the white horse as a cowboy might have done when going out on a day's work. Wade had to change his position to watch Belllounds, and his somber gaze followed him across the hill, down the slope, along the willow-bordered brook, and so on to the opposite side of the great valley, where Jack began to climb in the direction of Buffalo Park. After Belllounds had disappeared and had been gone for an hour, Wade went down on the other side of the hill, found his horse where he had left him, in a thicket, and, mounting, he rode around to strike the trail upon which Belllounds had ridden. The imprint of fresh horse tracks showed clear in the soft dust. And the left front track had been made by a shoe crudely triangular in shape, identical with that peculiar to Wilson Moore's horse. "Ahuh!" muttered Wade, in greeting to what he had expected to see. "Well, Buster Jack, it's a plain trail now--damn your crooked soul!" The hunter took up that trail, and he followed it into the woods. There he hesitated. Men who left crooked trails frequently ambushed them, and Belllounds had made no effort to conceal his tracks. Indeed, he had chosen the soft, open ground, even after he had left the trail to take to the grassy, wooded benches. There were cattle here, but not as many as on the more open aspen slopes across the valley. After deliberating a moment, Wade decided that he must risk being caught trailing Belllounds. But he would go slowly, trusting to eye and ear, to outwit this strangely acting foreman of White Slides Ranch.
