All four feet went from under the pony and he struck the ground on his side with a force that brought a grunt from him. In the cloud of dust the spectators thought that Grace had been caught under the horse and crashed. Emma Dean uttered a cry of alarm, and Nora Wingate turned her head away that she might not see.

"She's all right!" shouted Hiram Lang, who had sprung forward to give assistance if it were needed.

The pony had thrown itself on its right side. Mr. Lang found Grace sitting calmly on the side of the saddle, free of the body of the horse, but breathing heavily. Her quickness had been the means of her disengaging herself as the bronco threw himself to the ground.

After giving the black a few seconds on his side, the Overland Rider brought her crop down on his rump with a vicious whack. It stung. Like a flash the pony was on his feet, with Grace's feet now planted firmly in the stirrups.

As Grace had expected, the bucking was resumed the instant the pony felt the smart of the crop. How the dust did fly then, and how those cowboy wranglers did yell!

"Who's a tenderfoot!" howled Hippy Wingate. "Just watch her smoke."

Grace Harlowe's whole body was weary, but her grit was not diminishing in the least. However, she decided that the time had arrived when she must do a little fighting for herself, and not leave it all to the pony, so, having arrived at this decision, Grace watched narrowly for a favorable opportunity to begin.

The opportunity came a few seconds later when the horse threw up his head preparatory to pitching forward in another series of savage bucks. Grace jerked the animal's head to one side, brought her quirt down sharply, and, at the same time, jabbed the little black fighter with her spurs.

She continued to apply this treatment for several seconds until the bronco, goaded to a change of tactics, whirled and started away at a run, driving straight through the assembled crowd. The crowd fled for their lives with Grace unable now to do more than stay on the saddle.

The black had not gone far before he stopped as suddenly as he had started, stopped stiff-legged, braced himself and slid on his feet through the alkali for several yards.
