"You cut across the head of this slope and take up your position in the slide below the cave, say just by that big stone. From there you can command the cave, our position and your own. Now, if it is necessary to kill this lion to save me or Frank, or, of course, yourself, can you be depended upon to kill him?" I felt a queer sensation around my heart and a strange tightening of the skin upon my face! What a position for me to be placed in! For one instant I shook like a quivering aspen leaf. Then because of the pride of a man, or perhaps inherited instincts cropping out at this perilous moment, I looked up and answered quietly: "Yes. I will kill him!" "Old Tom is cornered, and he'll come out. He can run only two ways: along this trail, or down that slide. I'll take my stand by the scrub pinyon there so I can get a hitch if I rope him. Frank, when I give the word, let the dogs go. Grey, you block the slide. If he makes at us, even if I do get my rope on him, kill him! Most likely he'll jump down hill—then you'll HAVE to kill him! Be quick. Now loose the hounds. Hi! Hi! Hi! Hi!" I jumped into the narrow slide of weathered stone and looked up. Jones's stentorian yell rose high above the clamor of the hounds. He whirled his lasso. A huge yellow form shot over the trail and hit the top of the slide with a crash. The lasso streaked out with arrowy swiftness, circled, and snapped viciously close to Old Tom's head. "Kill him! Kill him!" roared Jones. Then the lion leaped, seemingly into the air above me. Instinctively I raised my little automatic rifle. I seemed to hear a million bellowing reports. The tawny body, with its grim, snarling face, blurred in my sight. I heard a roar of sliding stones at my feet. I felt a rush of wind. I caught a confused glimpse of a whirling wheel of fur, rolling down the slide. Then Jones and Frank were pounding me, and yelling I know not what. From far above came floating down a long "Waa-hoo!" I saw Wallace silhouetted against the blue sky. I felt the hot barrel of my rifle, and shuddered at the bloody stones below me—then, and then only, did I realize, with weakening legs, that Old Tom had jumped at me, and had jumped to his death. CHAPTER 13. SINGING CLIFFS Old Tom had rolled two hundred yards down the cañon, leaving a red trail and bits of fur behind him. When I had clambered down to the steep slide where he had lodged, Sounder and Jude had just decided he was no longer worth biting, and were wagging their tails. Frank was shaking his head, and Jones, standing above the lion, lasso in hand, wore a disconsolate face. "How I wish I had got the rope on him!" "I reckon we'd be gatherin' up the pieces of you if you had," said Frank, dryly.
