"Are you much of a rider?" asked the man, and again he winked at his companions.

"Pretty fair," replied Will, who did not like to boast. The truth was, he was the best rider around Lockport, but he did not know what was in store for him from the innocent-looking animal that trailed along so meekly at the saddle horn of Bill Case.

"You can try this one, if you like," went on the cattleman. "I've no objection. In fact I'd like to see some one ride him. Maybe he'd be more valuable then. He needs training, but I can't seem to do anything with him."

The truth of the matter was that the horse was one of the very worst types of "bucking broncos." That is, whenever a person got on his back he would jump up into the air, and come down on four feet stiffly, almost jarring the rider out of the saddle. In fact he usually did jar him off, or, if he could not get rid of the man on his back in that way, he had other tricks as bad as bucking.

Bill Case had bought the horse at the town where he had been with his employer's cattle, and he was taking the animal back to the ranch, mainly to use in cowboy sports, for a bucking bronco is not much use as a riding steed. Bill had tried, unsuccessfully, to ride the steed, that was all right, and gentle, as long as no one tried to get on its back.

By this time Mr. Harrison and Jed were some distance ahead. They were interested in talking about gold strikes to the two miners, and had, with Hurd and Curtin, unconsciously drawn away from Will, and the three cattlemen.

"Will you let me try him?" asked the boy, as he looked at the horse. He knew nothing of bucking broncos, though he had read about them. Still, there was no way of telling one by merely looking at it.

"Sure thing," replied Mr. Case. "Here's a nice level stretch. You can try him here," and he stopped, and unfastened the long rope. At the same time he whispered to his companions: "Watch the fun now."

Will, all unaware of what was in store for him, dismounted from his own patient, plodding horse, and approached the bronco.

"Jump right on his back," advised Bill Case. "You don't need a saddle."
