The pony forgot all his tricks, and leaping high into the air, he shot off like a streak toward the corral gate.

Once outside, he headed for the open plains, going with the speed of a racer on the track.
"They're off!" cried Roger.
"Don't let him throw you!" yelled Todd.
"Can't we ride after 'em ?" queried Phil.
"Sure we can ride after 'em," responded Todd.

"An' we better do it, too, fer there ain't no tellin' what that pony will do to Dave," he added, anxiously, and with a black look at Yates, which made the other cowboy cast his eyes to the ground.
On and on sped the bronco, with Dave sitting firmly in the saddle.

So long as the pony kept going, the lad felt he had nothing to fear.

But he was on the alert, for he did not know but that the animal would play another trick at any instant.
"Go on, old boy!" he muttered.
