As the ambulance drove away she waved cheerfully at him a gauntleted hand.

The cowpuncher turned back to the arena. The megaphone man was announcing that the contest for the world's rough-riding championship would now be resumed.

CHAPTER III

FOR THE CHAMPIONSHIP OF THE WORLD

The less expert riders had been weeded out in the past two days. Only the champions of their respective sections were still in the running. One after another these lean, brown men, chap-clad and bow-legged, came forward dragging their saddles and clamped themselves to the backs of hurricane outlaws which pitched, bucked, crashed into fences, and toppled over backward in their frenzied efforts to dislodge the human clothes-pins fastened to them.

The bronco busters endured the usual luck of the day. Two were thrown and picked themselves out of the dust, chagrined and damaged, but still grinning. One drew a tame horse not to be driven into resistance either by fanning or scratching. Most of the riders emerged from the ordeal victorious. Meanwhile the spectators in the big grand stand, packed close as small apples in a box, watched every rider and snatched at its thrills just as such crowds have done from the time of Caligula.

Kirby Lane, from his seat on the fence among a group of cowpunchers, watched each rider no less closely. It chanced that he came last on the programme for the day. When Cole Sanborn was in the saddle he made an audible comment.

"I'm lookin' at the next champion of the world," he announced.

"Not onless you've got a lookin'-glass with you, old alkali," a small berry-brown youth in yellow-wool chaps retorted.

Sanborn was astride a noted outlaw known as Jazz. The horse was a sorrel, and it knew all the tricks of its kind. It went sunfishing, tried weaving and fence-rowing, at last toppled over backward after a frantic leap upward. The rider, long-bodied and lithe, rode like a centaur. Except for the moment when he stepped out of the saddle as the outlaw fell on its back, he stuck to his seat as though he were glued to it.
