It was Bud's voice once more.

Somehow, Jack found himself in the saddle, with Firewater racing under him as that brave little bay had never raced before. Close alongside came Bud, rowelling his bleeding-kneed calico cruelly to keep alongside. Far behind came shouts and yells from the crowd. The buckskin, the cause of all the trouble, managed to clamber to the edge of the stream, where the water was slightly shallower, and was dragged out by ropes. While the race for life swept onward, she stood dripping and shivering on the summit of the bank.

From his flying pony Jack caught occasional glimpses of Ralph in the stream below. The boy was a good swimmer, and now that he was being carried along with the current, instead of fighting it, he was able to keep his head above water most of the time.

"Stick it out, Ralph, old boy!" yelled Jack, as he dashed past the half-drowned lad whom the rapid current was carrying almost as swiftly as the over-run ponies could gallop.

"We'll be in time!" exclaimed Jack, through his clinched teeth. Right ahead of him he saw some grim, gallows-like looking timbers reared up against the sky line, which he knew must mark the sluice.

Hardly had the thought flashed through his mind, when Firewater seemed to glide from beneath him. An instant later Jack found himself rolling over and over on the level plain.

The same accident as had befallen Bud had happened to him. A gopher hole—one of those pests of desert riders—had tripped Firewater and sent his rider sprawling headlong.

"Hurt?"

Bud Wilson, on the calico, drew up alongside Jack, who had struggled to his feet and was looking about in a dazed sort of way.
