He believed that the arrows had come from above, but whether from a point directly overhead or to the right or to the left he had no way of telling. It was a hidden foe that he had to combat, and this ignorance was the worst feature of his position. He did not know which way to turn, he did not know which road led to escape, but must lie in his narrow groove until the enemy attacked. He had learned from his comrades, experienced in the wilderness and in Indian warfare, that perhaps the greatest of all qualities in such surroundings was patience, and if it had not been for such knowledge he might have risked a third arrow long ago, but, as it was, he kept perfectly still, flattening himself against the cliff, sheltered by the edge of the natural bowl and the little terrace of stones he had built. He might have fired his rifle to attract the attention of his comrades, but he judged that they were at the camp and would not hear his shot. He would fight it out himself, especially as he believed that he was menaced by but a single Indian, a warrior who perhaps had been stalking the mountain sheep also, when he had beheld the creeping lad. Great as was the strength of the youth's will and patience, he began to twist his body a little in the stony bowl and seek here and there for a sight of his besieger. He could make out stony outcrops and projections above him, every one of which might shelter a warrior, and he was about to give up the quest when a third arrow whistled, struck upon the ledge that he had built and, instead of falling into the chasm, rebounded into the bowl wherein he lay. The barb had been broken by the rock against which it struck so hard, though the shaft, long, polished and feathered, showed that it had been made by an artist. But he did not know enough about arrows to tell whether it was that of a Sioux or of a warrior belonging to some other tribe. Looking at it a little while, he threw it into the chasm, and settled back to more waiting. The day was now well advanced and a brilliant sun in the slope of the heavens began to pour fiery shafts upon the side of the cliff. Will had usually found it cold at such a height, but now the beams struck directly upon him and his face was soon covered with perspiration. He was assailed also by a fierce, burning thirst, and a great anger lay hold of him. It was a terrible joke that he should be held there in the hole of the cliff by an invisible warrior who used only arrows against him, perhaps because he feared a shot from a rifle would bring the white lad's comrades.
