"He's goin' to steal the mail box now!" whispered Flossie to Freddie. "I hope Sable won't fall or anything."

Snap! snap! went the whip as the horse ran faster and faster.

All of a sudden Tom got a good tight hold on the reins, then he pulled up alongside of the mail coach, leaned over, grabbed the mail bag, and spurred his horse at full speed around the ring.

"Hurrah! hurrah!" shouted everybody.

"Well done!" called Uncle Daniel.

"Couldn't be better!" exclaimed Mr. Bobbsey.

Tom waved his hat now and patted Sable affectionately, as all good riders do when their horses have done well in the ring.

The men admired the little horse so much they came up and asked the "cowboy" a lot of questions about him, how old he was and who broke him in.

"One more number," called Bert. "The chariot race."

At this all took their seats again, and out trotted two clowns, Jack and August, each riding in a little goat wagon.
