It was a week later when I did something which those old guides could understand and appreciate--I made a dead shot. I committed a murder, and from that time, the brotherhood of pards was open to us, had we cared to join. It was all because I killed an antelope. Nimrod and I started out that morning with the understanding that, if we saw antelope, I was to have a chance. In about six miles, Nimrod spied two white specks moving along the rocky ridge to the east of us, which rose abruptly from the plain where we were. I was soon able to make out that they were antelope. But the antelope had also seen us, and there was as much chance of getting near to them, by direct pursuit, as of a snail catching a hare. So we rode on calmly northward for half a mile, making believe we had not seen them, until we passed out of sight behind a long hill. Then we began an elaborate detour up the mountain, keeping well out of sight, until we judged that the animals, providing they had not moved, were below us, under the rocky ledge nearly a mile back. We tied up the horses on that dizzy height, and stole, Nimrod with a carbine, I with the rifle, along a treacherous, shaly bank which ended, twenty feet below, in the steep rocky bluffs that formed the face of the cliff. Every step was an agony of uncertainty as to how far one would slide, and how much loose shale one would dislodge to rattle down over the cliff and startle the antelope we hoped were there. To move about on a squeaking floor without disturbing a light sleeper is child's play compared with our progress. A misstep would have sent us flying over the cliff, but I did not think of that--my only care was not to startle the shy fleet-footed creatures we were pursuing. I hardly dared to breathe; every muscle and nerve was tense with the long suspense. [Illustration: A MISSTEP WOULD HAVE SENT US FLYING OVER THE CLIFF.] Suddenly I clutched Nimrod's arm and pointed at an oblong tan coloured bulk fifty yards above us on the mountain. "Antelope! Lying down!" I whispered in his ear. He nodded and motioned me to go ahead. I crawled nearer, inch by inch, my gaze riveted on that object. It did not move. I grew more elated the nearer it allowed me to approach. It was not so very hard to get at an antelope, after all. I felt astonishingly pleased with my performance. Then--rattle, crash--and a stone went bounding down. What a pity, after all my painful contortions not to do it! I instantly raised the rifle to get a shot before the swift animal went flying away. But it was strangely quiet. I stole a little nearer--and then turned and went gently back to Nimrod. He was convulsed with silent and unnecessary laughter. My elaborate stalk had been made on--a nice buff stone.
