There has always been for me an overwhelming fascination in watching busters at work. They have underlying traits in common when it comes to handling the horses--the garrulous one becomes coldly watchful, the Stoic moves with stern patience, the boaster soothes with soft-crooned words and confident caress. Mullins left Corazón standing in the middle of the corral, the hackamore rope strung loose on the ground, while he saw to it that his spurs were fast. We mounted the fence, not wishing to be mixed in the glorious turmoil to follow. “I wouldn’t top ol’ Corazón for fifty,” confessed the man on the adjoining post. “Mullins has certainly got nerve,” I conceded. “A buster has got to have nerve.” The range boss delivered himself laconically. “All nerve and no brains makes the best. But they get stove up and then--” “And then? What then?” “Why, don’t you know?” he asked in surprise. “Every buster loses his nerve at last, and then they can’t ride a pack-hoss. It must be because it’s one fool man with one set of nerves up ag’in a new hoss with a new devil in him every time. They wear him down. Don’t you reckon?” The explanation sounded plausible. Mullins was listening with a faintly amused smile to Reb’s account of what a lady mule had done to him; he rolled a cigarette and lighted it painstakingly. The hands that held the match were steady as eternal rock. It was maddening to see him stand there so coolly while the big sorrel, a dozen feet distant, was a-quake with dread, blowing harshly through his crimson nostrils whenever a cowboy stirred--and each of us knowing that the man was taking his life in his hands. An unlooked-for twist, a trifling disturbance of poise, and, with a horse like Corazón, it meant maiming or death. At last he threw the cigarette from him and walked slowly to the rope. “So you’re calling for me?” he inquired, gathering it up. Corazón was snorting. By patient craft Reb acquired a grip on the sorrel’s ears, and, while he hung there, bringing the head down so that the horse could not move, Mullins tested the stirrups and raised himself cautiously into the saddle. “Let him go.” While one could count ten, Corazón stood expectant, his back bowed, his tail between his legs. The ears were laid flat on the head and the forefeet well advanced. The buster waited, the quirt hanging from two fingers of his right hand. Suddenly the sorrel ducked his head and emitted a harsh scream, leaping, with legs stiff, straight off the ground. He came down with the massive hips at an angle to the shoulders, thereby imparting a double shock; bounded high again, turned back with bewildering speed as he touched the earth; and then, in a circle perhaps twenty feet in diameter, sprang time after time, his heels lashing the air. Never had such pitching been seen on the Anvil Range. “I swan, he just misses his tail a’ inch when he turns back!” roared a puncher.
