It was a lovely exhibition. He bucked with his head up and his head between his knees. He bucked in a circle and in a straight line and then mixed both styles for variety. He made little spurts at full speed, leaped into the air, and came down stiff-legged at the end of the run, his head between his braced forefeet, and then he whirled as if on a peg and darted back the other way. He bucked criss-cross, jumping from side to side, and he interspersed this with samples of all his other kinds of bucking thrown in. That the doctor stuck on the saddle was a miracle beyond belief. Of course he pulled leather shamelessly throughout the contest, but riding straight up is a good deal of a myth. Fancy riding is reserved for circus men. The mountain-desert is a place where men stick close to utility and let style go hang. And the doctor stuck in the saddle. He had set his teeth, and he was a sea-sick greenish-white. His hat was a-jog over one ear--his shirt tails flew out behind. And still he remained to battle. Aye, for he ceased the passive clinging to the saddle. He gathered up the long quirt which had hitherto dangled idly from his wrist, and at the very moment when the piebald had let out another notch in his feats, the doctor, holding on desperately with one hand, with the other brandished the quirt around his head and brought it down with a crack along the flanks of the piebald. The effect was a little short of a miracle. The mustang snorted and leaped once into the air, but he forgot to come down stiff-legged, and then, instantly, he broke into a little, soft dog trot, and followed humbly in the trail of the black stallion. The laughter and cheers from the house were the sweetest of music in the ears of Doctor Randall Byrne; the most sounding sentences of praise from the lips of the most learned of professors, after this, would be the most shabby of anticlimaxes. He waved his arm back to a group standing in front of the house--Buck Daniels, Kate, the lantern-jawed cowboy, and Wung Lu waving his kitchen apron. In another moment he was beside the rider of the stallion, and the man was whistling one of those melodies which defied repetition. It simply ran on and on, smoothly, sweeping through transition after transition, soaring and falling in the most effortless manner. Now it paused, now it began again. It was never loud, but it carried like the music of a bird on wing, blown by the wind. There was about it, also, something which escaped from the personal. He began to forget that it was a man who whistled, and such a man! He began to look about to the hills and the sky and the rocks--for these, it might be said, were set to music--they, too, had the sweep of line, and the broken rhythms, the sense of spaciousness, the far horizons.
