On the fourth morning he rode anxiously up the valley, fearing that the horses had been stolen in the night, yet hoping they had merely strayed up the creek to find fresh pastures. A light breeze that carried the keen edge of frost made his nose tingle. His horse trotted steadily forward, as keen on the trail as Buddy himself; keener, for he would be sure to give warning of danger. So they rounded a bend in the creek and came upon the scattered fringe of the remuda cropping steadily at the meadow grass there. Bud circled them, glancing now and then at the ridge beyond the valley. It seemed somehow unnatural--lower, with the stars showing along its wooded crest in a row, as if there were no peaks. Then quite suddenly he knew that the ridge was the same, and that the stars he saw were little, breakfast camp-fires. His heart gave a jump when he realized how many little fires there were, and knew that the dance was over. The Indians had left the reservation and had crossed the ridge yesterday, and had camped there to wait for the dawn. While he gathered his horses together he guessed how old Colorou had planned to catch the Tomahawk riders when they left camp and scattered, two by two, on “Circle.” He had held his band well out of sight and sound of the Big Creek cabin, and if the horses had not strayed up the creek in the night he would have caught the white men off their guard. Buddy looked often over his shoulder while he drove the horses down the creek. It seemed stranger than luck, that he had been compelled to ride so far on this particular morning; as if mother's steadfast faith in prayer and the guardianship of angels was justified by actual facts. Still, Buddy was too hard-headed to assume easily that angels had driven the horses up the creek so that he would have to ride up there and discover the Indian fires. If angels could do that, why hadn't they stopped Colorou from going on the warpath? It would have been simpler, in Buddy's opinion. He did not mention the angel problem to his father, however. Bob Birnie was eating breakfast with his men when Buddy rode up to the cabin and told the news. The boys did not say anything much, but they may have taken bigger bites by way of filling their stomachs in less time than usual. “I'll go see for myself,” said Bob Birnie. “You boys saddle up and be ready to start. If it's Indians, we'll head for Laramie and drive everything before us as we go. But the lad may be wrong.” He took the reins from Buddy, mounted, and rode away, his booted feet hanging far below Buddy's short stirrups. Speedily he was back, and the scowl on his face told plainly enough that Buddy had not been mistaken. “They're coming off the ridge already,” he announced grimly. “I heard their horses among the rocks up there. They think to come down on us at sunrise. There'll be too many for us to hold off, I'm thinking. Get ye a fresh horse, Buddy, and drive the horses down the creek fast as ye can.”
