He was in no danger of losing the way, for his path was walled in for him. Towards midday it ceased to go up, up, up, and the chasm widened into a great rocky canon of wonderful ruggedness and beauty. Two Arrows had been among the mountains before, in other ranges, and this seemed to him very much like what he might have expected. Now, however, the trail turned to the right and picked its way along the steep side of the varying slopes. Here it was wider and there it was narrower, until it came to a reach of natural roadway that even a bison must have hunted for before he found it. Away up it went in zigzags, seeming to take skilful advantage of every natural help it came to, and then it shot along the mountain-side for a thousand feet, traversing a mere ledge, where one formation of rock projected out below another and made a shelf for it to go upon. If a man had fallen from that shelf he would have gone down a tremendous depth upon jagged rocks at the bottom of the canon. Two Arrows wasted no time in useless observations or admiration. Where herd after herd of wild cattle had tramped before him he could surely follow, and at the end of that ledge the road began to descend. The descent was gradual, and uncommonly free from breakages. It led, before a great while, once more to the bottom of the gorge. Several times Two Arrows saw "big-horn" or Rocky Mountain sheep among the rocks above him, far out of the reach of his arrows. He felt a longing for antelope venison, but there was no use in trying to catch one of those fellows. Hotter than anything else he felt the fever and fire of his ambition, stirring him to push on and do more than he had ever heard of as done by any other boy of his age among all the bands of his nation. It made him walk fast and firmly in the bracing mountain air, and he drew his breath somewhat quickly at times, when he thought of the wonderful things which might be before him. He had no watch, but just as the sun stood nearly over his head, or, rather, over the middle of the great gorge, he could see that this was beginning to grow broader and not so steep. It was promising to lead out into something, and One-eye dashed on ahead as if to ascertain what it might be. Two Arrows stood still for a moment and watched him, and then he started as if something had pricked him. The dog was crouching and creeping as if he had his remaining eye upon game of some sort or on danger. His master also crouched and crept, slipping forward rapidly from rock to rock. In three minutes more he lay beside One-eye, and they both had something worth while to look at. Not more than three hundred yards beyond them, on the crest of a rocky ledge that came out from the mountain-side like an abutment, stood a big-horn antelope. He had seen One-eye and was looking at him. He may have been studying whether or not it could be needful for an antelope away up where he was to spring away any farther from a dog and an Indian boy.
