For a few minutes I sat still upon my crag, puzzling. Some one has stumbled into a bear trap, I thought, or been injured in a fall. After marking the locality from which the calls came, I ran down my zigzag trail, and hastened down the valley toward the spot whence the cries had come. Whenever I came to the open, parklike clearings, I stopped to listen. The floor of the wide valley had been burned over scores of years before, and a new growth of lodge-pole pines covered it. These trees were of nearly uniform height, about fifteen feet, and in places too dense to permit of passage. Three miles were covered in record time. Then, thinking that I must be close to the spot from which the calls had come, I climbed an upthrust of rock, searched the openings among the trees near by, and listened intently. I shouted; no reply. For perhaps ten minutes I waited. Then from far up the valley, close below my cabin, the distressing calls were repeated. "He's certainly not crippled," I thought. "He's traveled nearly as far as I." I set off at a run, for I know every little angle of the woods in the vicinity. But when I arrived, breathless and panting, there was no answer to my shouts. I gave up the chase in disgust, and started up the trail toward my cabin. I decided some one was having fun with me. Midway up the trail to my cabin, I heard the cries again, agonized, fearful. They came from across the valley, toward the west. Heading for the peaks! I must stop him! It certainly sounded serious. I'd have to see it through. I hurried across the valley, shouting at intervals, stopping to listen and to look for the person in distress. There was no answer, no one in sight. As I reached the steep slope, leading upward to the high peaks, I heard terrified, heart-rending cries, southward, toward the spot from which the first call had come. It was strange, and maddening, that I could hear him so distinctly, yet he could not hear me. He was certainly deaf or very stupid, for he continued calling for help, when help was pursuing him and yelling at the top of its lungs. Again calls. This time straight south of my position. It was a riddle; annoying, yet interesting. Never in my mountain experience had I encountered such a mystifying situation. However, with grim determination, but little enthusiasm, I turned south. My curiosity was aroused. I wanted to see what sort of fool ran around in dizzy circles yelling for help, yet not waiting for an answer to his supplications, nor acknowledging my answering shouts.
