It was an awful moment for Sile. He had never before done as much real thinking in one hour as he did between his first glimpse of that redskin and the rising of the dark, threatening line of that rifle-barrel.
He had thought of the men at the mine, and of their need of warning, and therefore of the necessity that he should protect himself and get to them alive. He had thought of his father and his mother, and of some other people, and he had also thought what a dreadful thing it was to shoot straight at a man, and perhaps to kill him. He had just said to himself,
"I might just kill his horse, and then I could get away from him."
At that very instant the two rifles came to a level, whether he would or not. He felt no symptoms of "buck ague" this time, for every nerve and muscle of his body was stiffening, while his tired horse stood as still as a stone. That was where he had a priceless advantage. The spirited animal ridden by his enemy was a trifle restive for some reason, and caused a shade of delay that was just enough to give Sile his only remaining chance.
"If I hit his horse in the head," he was thinking as he pulled the trigger: but that would have been close shooting at a hundred yards, and just beyond the head of the horse was the naked breast of the warrior.
There were two reports close together, and Sile felt something prick him sharply on the left arm near the shoulder. At the same moment he saw the red man reel to and fro upon his horse, and then pitch off head foremost into the grass.
"Oh, dear me, I've shot him!" he exclaimed, and his first impulse was to ride away as fast as he could.
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."
