He held out his hand, and Sile shook it hard in token of good-bye, and the two boys separated, each to carry his own tidings and face his own dangers. Two Arrows rode on in a straight line up the valley, and Sile wheeled towards the line of forest which bordered the river. It struck him that he was yet a little below the precise neighborhood of the mine, and he was correct, but as yet it was all guess-work. At all events, he was sure that his remaining ride could not be a long one; it could not fail to be intensely exciting. Again he saw plenty of game, and he was strangely tempted to try a shot at a deer until the idea came to him, "I can't say what ears might hear the report of my rifle." Deer did not seem to be of any account after that idea took form, and he galloped on. In a few minutes more his horse's feet were in the water, and he was almost immediately aware that he had not chosen a good ford. It grew deep too fast, and he had to ride out again. "I won't go into another pool," he said to himself. "I'll hunt for a wide place where it ripples well." He had not the experience and the quick eyes of Two Arrows, but he was learning fast, and it was easy to find a better crossing. Once over, he felt that the forest was itself a sort of protection, and there came a great thrill all over him at the thought of riding out from under it. What if the Apaches should be already there, and what if they had found the camp and destroyed it? "They haven't done that," said Sile, "unless they managed to take it by surprise. Guess they couldn't do that in broad daylight. Our men are all old hands, and Yellow Pine keeps his eyes about him. I'll get in a good while before dark--that is, if I make out to get in. I wish there was good cover all the way." He drew rein for a moment under the last line of trees, and he looked earnestly in all directions, but even his spy-glass could not reveal to him a sign of danger. He had never seen anything more absolutely quiet and peaceful than was that stretch of open valley, with its grass and its bushes, and its clusters of grand old trees. It encouraged him a good deal to see a buck and two does feeding within a quarter of a mile of him, and he at once rode watchfully onward. His horse was beginning to show signs of hard riding, and he noted it regretfully. There might yet be a race to run, for all he knew. There was to be something very different from a race, and the notice of it came to him very suddenly. Just as he rode out through a patch of willows in a long hollow, walking his horse because of their being in his way a little, his heart seemed to stop beating and stand still. Then it beat again, and like a trip-hammer, for a moment. The bridle fell from his hand, and he made ready his rifle as if by an instinctive movement.
