"I wonder what he has up his sleeve," mused Mr. Sparling shrewdly, suspecting that Phil was about to try something he had never done in the ring before. "I hope he won't take any long chances, for I can't afford to have anything happen to my little star performer."

As a matter of fact both Phil and Teddy Tucker had become star performers, and were so featured on the circus bills, where their pictures had been placed for this, their third season out. The year before they had appeared on the small bills in the shop windows, but now they had the satisfaction of seeing themselves portrayed in life-size on the big boards.

Phil sent his ring horse forward at a lively gait, which grew faster and faster, as he sat lightly on the animal's rump, urging it along.

All at once he bounded to his feet, poised an instant, then threw himself into a succession of handsprings until he resembled a whirling pink and gold wheel.

This was a new act in the circus world, and such of the other performers as were under the big top at the moment paused to watch it.

No one was more surprised than Mr. Sparling himself. He knew what a difficult feat it was that the Circus Boy had not only essayed, but succeeded in doing. Phil kept it up at such length, and with such stubborn persistence, that the owner of the show feared lest the lad, in his dizziness might get a bad fall.

Doing a series of such rapid handsprings on the level ground is calculated to make a performer's head swim. But how much more difficult such an effort is on the slippery back of a moving horse may well be imagined.

Finally, red of face, panting, breathless, Phil Forrest alighted on his feet, well back on the ring horse's rump.

"Be ready to catch me," he gasped.

The ringmaster understood.
