The action of the horse he understood. On the sudden flight of his master he had attempted to follow him among the rocks and trees of the ridge; the Indians, in the flurry of the occasion, paying no attention to him. Failing, he was making his way back to the open prairie, when the sight of his master sent him galloping after him; Warren being too panic-stricken to suspect the truth until he was well-nigh run down by the faithful animal. "Heaven bless you, Jack!" he exclaimed, with glowing face and joyous heart; "you are in the nick of time." Saddle and trappings were unharmed, though the tapering limbs of the creature had been scratched and cut by his attempt to follow his master. The youth was in the saddle in a twinkling, and, but for the sad situation of Tim Brophy, he would have uttered a shout of triumph. For in truth he felt safe, even though the hostiles were dangerously near. Remembering this, he rode farther out from the ridge, and whooped and swung his arms at the Indian ponies, who dashed still farther out on the plain. It was inevitable that this tumult should become known to the captors of Tim Brophy. Young Starr expected it, and therefore was not surprised when he saw the figures of several warriors at the base of the ridge. He could not forbear swinging his Winchester over his head and taunting them. They replied with several shots, but the distance was too great for Warren to feel any alarm. He, too, discharged his gun at the group, and acted as if he meant to challenge them to come out and attack him. If such were his intentions, the challenge was accepted. Several warriors ran out on the prairie, calling to their ponies, in order that they might mount and take up the pursuit. Their action caused the youth no alarm, for the test of speed had already been made, and he feared none of the Indian animals. The latter may have been under good discipline when their masters were astride of them, but they showed anything but obedience now that they were free from their control. They kept trotting about in circles, and avoided the warriors with a persistency that must have been exasperating to them. Only one displayed consideration for his master. He was among the fleetest, and after some coy dallying he stood still until the athletic Sioux came beside him. He vaulted upon his back, and then accepted the seeming challenge of the youth. The latter had checked his steed at a safe distance on the snowy plain, and confronted the Indian party. Looking beyond the warrior nearest him, he strove to catch sight of Tim Brophy; but he was too far off, and the trees interfered with his vision. Before he could continue the scrutiny long, the mounted Sioux demanded his attention. Prudence would have suggested that now, since young Starr was well mounted, he should take no chances, but scurry away at the top of his speed, leaving the discomfited warrior to nurse his chagrin over the clever trick played upon him.
