Then came a suggestion that the brave might be only wounded, and that it was his duty to go and see if he could do anything for him. With that, too, there came a great gush of curiosity and a fierce and feverish sense of triumph. He had fought a duel on horseback with an Indian warrior, with rifles, and there were no other white boys who could say that they had done that. He sat still upon his horse for a moment, and his breath came and went very quickly, and then he somewhat cautiously rode forward. The Indian's horse had bounded away for a little distance when his master fell, but was now standing and looking at him, as if in doubt as to what he ought to do next. Not another human being of any kind was to be seen, but Sile looked around him anxiously enough to make sure that he was alone. Not one sound disturbed the peaceful silence of the valley after those two rifles had spoken. All irresolution passed out of Sile's mind as he rode forward, for he felt that he had behaved rightly, and had done nothing for which he could blame himself. He watched the fallen man narrowly as he drew near him, but there was no motion or any other sign of life. "I must have killed him outright!" He sprang from his horse and bent over the prostrate form, but he did not have to look more than once. "That hole--that's where the bullet went in. It must have gone right through his heart. Well, he would have killed me if I had not killed him. I would not have hurt him if I could have helped it." It seemed to Sile a matter of course that he should pick up the red warrior's rifle, unbuckle and take off the bead-worked belt that carried his knife and revolver, take his lance, catch his horse, and then ride onward, carrying with him all as "spoils of war." He did it coolly and steadily but rapidly, and without any idea how very fast he was growing. He was learning lessons in a great school, but any wise old man could have told him that no two boys learn the same lessons anywhere. A good deal more depends upon the boy himself than upon the school or the teacher. That tall, brawny Apache warrior had been a distinguished brave, and he had been sent upon a scouting trip away in advance of the rest merely as a customary precaution. There had been no expectation that he would discover anything remarkable. In meeting a solitary pale-face, he had undertaken to kill him very much as a matter of course, for he was just then at war with all white men. Sile had made the better shot of the two, and that was about all that could be said. As for Sile, he was in a greater hurry than ever to get to the mine, and again and again he wondered whether Two Arrows had met any Apaches. "I do hope he hasn't," he said to himself, "with only a bow and arrows. I wish he had a rifle." CHAPTER XXV A MIDNIGHT MARCH
