It was decided that they had travelled far enough for one day, but that an early start should be made the next morning. That had also been an interesting day at the camp by the spring. The over-wearied pale-faces slept well, but Yellow Pine arose three times to go around among the animals and see how they were doing. He had them all fed and rubbed down most carefully in the morning. It was a good thing to do, and when Sile Parks awoke and stretched himself, he felt as if he also wanted to be fed and rubbed down. Almost everybody else was already astir, and breakfast was soon ready for him. Yellow Pine did a deal of exploring, before and after he breakfasted, and Sile at once set out to imitate him. He asked some question or other of every one he saw, and believed that he had learned a great deal. At last he came to a heap of stones and bushes that seemed to him to have been piled up remarkably. "How could they ever have got there?" he said, as he began to pull upon a bush with green leaves yet clinging to its twigs. In five minutes more he knew where the Nez Perces had made their hasty "cache" for their lodges and other treasures, and he went at once to report it to his father and to Yellow Pine. The latter looked at Sile with positive respect, and exclaimed, "There now, jedge; that settles it. I know I'm right; them Indians had lost their ponies. I couldn't find a hoof-mark on their trail this morning; they dragged some lodge-poles along, though. I say, we must leave their cache jest as we found it. We must foller right along, too, or we'll run short of fodder. They've taken my old road. We needn't be afraid of 'em, only we'd best keep a sharp lookout." Horses and mules and all felt as if a day's rest would be as good as a treat; but after all was said and done it was decided to keep moving. The start made was not an early one, and there was work for all hands here and there. The herds of bisons had not prepared that road for the passage of wagon wheels, and it needed the axe in one place and the crow-bar in another before the teams could pass. There was no sort of danger that the Nez Perces would be caught up with by the mining-party, and Yellow Pine seemed to breathe more freely at the end of every mile. "No, jedge," he said; "we won't have to leave the outfit anywhere. There'll be a heap of hard work at some spots, but we can make our way through, and we can come and go by this track forever after it's well opened." Sile Parks learned a great deal that day about the mysteries of road-making; he also learned how much a really well-built wagon will stand if it is not too heavily loaded. For all that, however, the best part of his time was expended in staring at the peaks, and in searching the walls of the canon for traces of gold and silver ore. "Father," said he at last, at a place where the wagons were "stuck" for a while, "I'm going ahead to see what'll turn up." "Don't go too far, that's all."
