Not a bit surprised was I to see a cougar break out of the green, and go tearing down the slide. In less than six seconds, I had sent six steel-jacketed bullets after him. Puffs of dust rose closer and closer to him as each bullet went nearer the mark and the last showered him with gravel and turned him straight down the canyon slope.

I slid down the dead pinyon and jumped nearly twenty feet to the soft sand below, and after putting a loaded clip in my rifle, began kangaroo leaps down the slope. When I reached the point where the cougar had entered the slide, I called the hounds, but they did not come nor answer me. Notwithstanding my excitement, I appreciated the distance to the bottom of the slope before I reached it. In my haste, I ran upon the verge of a precipice twice as deep as the first rim wall, but one glance down sent me shatteringly backward.

With all the breath I had left I yelled: "Waa-hoo! Waa-hoo!" From the echoes flung at me, I imagined at first that my friends were right on my ears. But no real answer came. The cougar had probably passed along this second rim wall to a break, and had gone down. His trail could easily be taken by any of the hounds. Vexed and anxious, I signaled again and again. Once, long after the echo had gone to sleep in some hollow canyon, I caught a faint "Wa-a-ho-o-o!" But it might have come from the clouds. I did not hear a hound barking above me on the slope; but suddenly, to my amazement, Sounder's deep bay rose from the abyss below. I ran along the rim, called till I was hoarse, leaned over so far that the blood rushed to my head, and then sat down. I concluded this canyon hunting could bear some sustained attention and thought, as well as frenzied action.

Examination of my position showed how impossible it was to arrive at any clear idea of the depth or size, or condition of the canyon slopes from the main rim wall above. The second wall—a stupendous, yellow-faced cliff two thousand feet high—curved to my left round to a point in front of me. The intervening canyon might have been a half mile wide, and it might have been ten miles. I had become disgusted with judging distance. The slope above this second wall facing me ran up far above my head; it fairly towered, and this routed all my former judgments, because I remembered distinctly that from the rim this yellow and green mountain had appeared an insignificant little ridge. But it was when I turned to gaze up behind me that I fully grasped the immensity of the place. This wall and slope were the first two steps down the long stairway of the Grand Canyon, and they towered over me, straight up a half-mile in dizzy height. To think of climbing it took my breath away.

Then again Sounder's bay floated distinctly to me, but it seemed to come from a different point. I turned my ear to the wind, and in the succeeding moments I was more and more baffled. One bay sounded from below and next from far to the right; another from the left. I could not distinguish voice from echo. The acoustic properties of the amphitheater beneath me were too wonderful for my comprehension.

As the bay grew sharper, and correspondingly more significant, I became distracted, and focused a strained vision on the canyon deeps. I looked along the slope to the notch where the wall curved and followed the base line of the yellow cliff. Quite suddenly I saw a very small black object moving with snail-like slowness. Although it seemed impossible for Sounder to be so small, I knew it was he. Having something now to judge distance from, I conceived it to be a mile, without the drop. If I could hear Sounder, he could hear me, so I yelled encouragement. The echoes clapped back at me like so many slaps in the face. I watched the hound until he disappeared among broken heaps of stone, and long after that his bay floated to me.

Having rested, I essayed the discovery of some of my lost companions or the hounds, and began to climb. Before I started, however, I was wise enough to study the rim wall above, to familiarize myself with the break so I would have a landmark. Like horns and spurs of gold the pinnacles loomed up. Massed closely together, they were not unlike an astounding pipe-organ. I had a feeling of my littleness, that I was lost, and should devote every moment and effort to the saving of my life. It did not seem possible I could be hunting. Though I climbed diagonally, and rested often, my heart pumped so hard I could hear it. A yellow crag, with a round head like an old man's cane, appealed to me as near the place where I last heard from Jim, and toward it I labored. Every time I glanced up, the distance seemed the same. A climb which I decided would not take more than fifteen minutes, required an hour.

While resting at the foot of the crag, I heard more baying of hounds, but for my life I could not tell whether the sound came from up or down, and I commenced to feel that I did not much care. Having signaled till I was hoarse, and receiving none but mock answers, I decided that if my companions had not toppled over a cliff, they were wisely withholding their breath.

Another stiff pull up the slope brought me under the rim wall, and there I groaned, because the wall was smooth and shiny, without a break. I plodded slowly along the base, with my rifle ready. Cougar tracks were so numerous I got tired of looking at them, but I did not forget that I might meet a tawny fellow or two among those narrow passes of shattered rock, and under the thick, dark pinyons. Going on in this way, I ran point-blank into a pile of bleached bones before a cave. I had stumbled on the lair of a lion and from the looks of it one like that of Old Tom. I flinched twice before I threw a stone into the dark-mouthed cave. What impressed me as soon as I found I was in no danger of being pawed and clawed round the gloomy spot, was the fact of the bones being there. How did they come on a slope where a man could hardly walk? Only one answer seemed feasible. The lion had made his kill one thousand feet above, had pulled his quarry to the rim and pushed it over. In view of the theory that he might have had to drag his victim from the forest, and that very seldom two lions worked together, the fact of the location of the bones as startling. Skulls of wild horses and deer, antlers and countless bones, all crushed into shapelessness, furnished indubitable proof that the carcasses had fallen from a great height. Most remarkable of all was the skeleton of a cougar lying across that of a horse. I believed—I could not help but believe that the cougar had fallen with his last victim.

Not many rods beyond the lion den, the rim wall split into towers, crags and pinnacles. I thought I had found my pipe organ, and began to climb toward a narrow opening in the rim. But I lost it. The extraordinarily cut-up condition of the wall made holding to one direction impossible. Soon I realized I was lost in a labyrinth. I tried to find my way down again, but the best I could do was to reach the verge of a cliff, from which I could see the canyon. Then I knew where I was, yet I did not know, so I plodded wearily back. Many a blind cleft did I ascend in the maze of crags. I could hardly crawl along, still I kept at it, for the place was conducive to dire thoughts. A tower of Babel menaced me with tons of loose shale. A tower that leaned more frightfully than the Tower of Pisa threatened to build my tomb. Many a lighthouse-shaped crag sent down little scattering rocks in ominous notice.
