THEN BEGAN A SERIES OF AMAZING BUCKS.

This was quickly done and Dynamite stood free, but still blindfolded. Jack poised on his tip toes and gave a light run forward. His hands were seen to touch the saddle and the next instant he was in it. He leaned forward and lifted the blindfold.

For an instant Dynamite stood shivering, his ears laid back, his eyes rolling viciously. Then, before the broncho knew what had happened, Jack’s quirt came down on his flank heavily.

“Yip!” yelled the cow–punchers.

“Yip! Yip!” called Jack, and hardly had the words left his mouth before he was flying through the air over the pony’s head. Dynamite’s first buck had unseated him. Mr. Reeves ran forward anxiously as Jack plowed the ground. But his anxiety was needless. By the time he reached the boy’s side Jack was up again, brushing the dirt of the corral from his clothing. He was pale but determined.

“You see, I told you it was impossible,” said the ranch owner. “Give it up.”

“Give it up!” exclaimed Jack. “Why, I’ve only just begun.”

“The kid’s got grit,” exclaimed a cowboy who had heard this last.
