How could I tell that I myself was not invisible? I hauled myself up short there for I realized that such folly was not good to have tumbling around in my brain. I figuratively pulled myself back to earth, and to steady my nerves reached into my pack and brought out several hard bits of bannock that I had stored there. I was dreadfully hungry and I munched these with enthusiasm, meanwhile keeping a sharp eye out for Big Pete, and between times making the acquaintance of the little chief hare who, as he scuttled about among the rocks, looked me over curiously. A short distance to my left was a huge obsidian cliff, the glassy walls of which rose in a precipice to a considerable height. On account of its peculiar formation, this crag of natural glass had several times attracted my attention, and on any other occasion I would have been curious enough to give it closer inspection. Once, as I turned my head in that direction, I thought I heard a wild laugh and later concluded that it was only imagination on my part, but now, as I again faced the cliff, I unmistakably heard a shout and was considerably relieved to see silhouetted against the sky the figure of Big Pete. “Hello, Le-loo,” he shouted. “Through chasin’ that ’ere spook Indian kid be you? It’s about time. Gosh-all-hemlocks! I been breakin’ my neck tryin’ to keep up with you, doggone yore hide,” shouted the big guide as he started to climb down toward me. “Hello, Pete! You bet I’m through and I’m blamed near all in. Where are we, do you know?” I called to him. “Top o’ the world, my boy. Top o’ the world, that’s whar we be,” he said with a grin. I had seen no game since I had lost the bighorn, and the sunball was now hung low in the heavens. It appeared to me that there was every prospect for a supperless night, too. But Big Pete evidently had no such idea, and he “’lowed” that he would “mosey” ’round a bit and kill some varmints for grub. There seemed to be plenty of mountain lion signs, and I was surprised that they should frequent such high altitudes, but Pete told me that they were up here after marmots, and were all sleek and fat on that diet. I would not have been surprised if my wild comrade had proposed a feast on these cats. But it was not long before Pete’s revolvers could be heard barking and in a short time he returned with two braces of white ptarmigan, each with its head shattered by a pistol ball, and I confess these birds were more to my liking than cat meat. Up there ’mid the snow fields the ptarmigan apparently kept their winter plumage all year round, and their natural camouflage made them utterly invisible to me, but to Pete, a white ptarmigan on a white snowfield seemed to be as easy to detect as if the same bird had been perched on a heap of coal. I had not seen one of these grouse since we had been in the mountains and was not aware of their presence until my companion returned with the four dead birds.
