It would not do to forget the country in front. While their chief interest lay to the rear, they were liable to run into some peril that would undo all the good gained by outrunning their pursuers. Warren saw that while they had swerved to the left, yet the course of the ridge would carry them to its base, unless they diverged still more from the direct path. And yet this divergence must be made as gradual as circumstances would permit, since otherwise great advantage would be given their enemies by the chance to "cut across lots," or in other words to follow a straight line, while offsetting the curved course of the fugitives. Directing the attention of Tim to the situation, he begged him to give no further thought to firing upon their foes. "I'll let the spalpeens alone if they'll do the same wid me," was his reply, spoken in a low voice, for the two were separated by only a few feet. "You can't have as good luck a second time." "But," persisted Tim, "if I hadn't dropped that felly, he would have tumbled you or mesilf out of the saddle, as he was about to do whin I jumped on him wid both feet." But Warren begged him to desist, confident as he was that any further attempt would result in ill to them. Tim held his peace, but leaving his friend to watch where they went he gave his chief attention to the Sioux, whose leaders, if they were not gaining ground, seemed to be holding their own. Suddenly, to Warren's disgust, his companion again brought his gun to his shoulder. Before he could aim and fire, however, one of the bucks discharged his weapon and the bullet nipped the leg of young Starr, who continued leaning forward, so as to offer as little of his body as possible for a target. Tim fired, but more than likely the ball went wide of the mark. His companion hoped that the act of their pursuers in shooting was caused by their fear of losing the fugitives through the speed of their ponies. But a short distance was necessary before the boys were riding in a line parallel with the ridge that had loomed up in their path. This gave them an open country for an unknown distance, over which to continue their flight, but it was hardly to be supposed that it would continue long. The section was too broken to warrant such a hope. It may have been the perception of the fugitives' object that brought the shot from the Sioux. At any rate, if it should become manifest that the young ranchers were drawing away, the rifles of the pursuers were certain to be brought into effective use, and the distance between the parties was fearfully brief. CHAPTER XXI. AWAY WE GO! One recourse was before the pursuing Sioux from the start: that was to shoot the horses of the fugitives. The wonder was that they had not aimed to do so from the first. With the couple dismounted, they would be at their mercy.
