"Go it, Chunky! Go it!" he encouraged.

"I am going," floated back to Tad faintly, causing him to laugh so heartily that he was nearly unhorsed when his pony rose to the hurdle.

As Stacy's mount cleared the last barrier, the fat boy fell forward on the pony's neck, which he grasped wildly, for the saddle in that final leap had, with disheartening suddeness, given way beneath him, slipping clear down under the animal's stomach.

Nothing daunted, Stacy, with his newly discovered grit, worked both spurs vigorously, eyes staring straight ahead of him over the head of his fleeing pony.

They were almost at the finish. Now the dust of the two cowboy leaders in the race did not smite him in the face as heretofore. He was too close up with them for that.

All at once the lad realized that he was gaining. Excitement among the spectators ran high. Observing his predicament and understanding full well the grit he was exhibiting, they were yelling like mad. Chunky began to yell also, uttering a series of shrill whoops, using voice and spurs incessantly, urging the pony to the goal.

The black pony, almost gray with the dust that had settled on his sleek, glossy coat, forged ahead in a noble sprint with head on a level with its back, nose reaching for the finish.

A roar of applause sounded in the fat boy's ears. Yells, cat calls and shrill whoops rent the air.

All at once a pistol barked, the black pony's feet plowed the dust, bringing it to a sharp halt.

The suddenness of the movement caused Chunky's feet to rise straight up into the air. For a few brief seconds he was standing on his head on the pony's neck like a circus performer.
