"I'll take you," he said.

A high, thrilling whistle came faintly from the distance.

"That fellow on the black horse down the road," said Lee Haines, "I guess he's the one that can hit the four dollars? Ha! ha! ha!"

"Sure," grinned Silent, "listen to his whistle! We'll see if we can drag another bet out of the bar-keep if the roan doesn't hurt him too bad. Look at him now!"

Morgan was having a bad time getting his foot in the stirrup, for the roan reared and plunged. Finally two men held his head and the saloon-keeper swung into the saddle. There was a little silence. The roan, as if doubtful that he could really have this new burden on his back, and still fearful of the rope which had been lately tethering him, went a few short, prancing steps, and then, feeling something akin to freedom, reared straight up, snorting. The crowd yelled with delight, and the sound sent the roan back to all fours and racing down the road. He stopped with braced feet, and Morgan lurched forwards on the neck, yet he struck to his seat gamely. Whistling Dan was not a hundred yards away.

Morgan yelled and swung the quirt. The response of the roan was another race down the road at terrific speed, despite the pull of Morgan on the reins. Just as the running horse reached Whistling Dan, he stopped as short as he had done before, but this time with an added buck and a sidewise lurch all combined, which gave the effect of snapping a whip—and poor Morgan was hurled from the saddle like a stone from a sling. The crowd waved their hats and yelled with delight.

"Look out!" yelled Jim Silent. "Grab the reins!"

But though Morgan made a valiant effort the roan easily swerved past him and went racing down the road.

"My God," groaned Silent, "he's gone!"

"Saddles!" called someone. "We'll catch him!"
