Jumbo’s heels flew into the air, then began a series of lunges, bucking and terrific kicking such as none among the vast audience ever had witnessed in or out of a show ring.

One instant Teddy would be standing on his head on the mule’s back, the next lying on his back with feet toward the animal’s head. Next he would be dragged along the ground, to be plumped back again at the next bounce.

No feat seemed too difficult for Jumbo to attempt that day.

“Stop him! Stop him!” howled the ringmaster.

Ring attendants rushed forward to obey his command, but they might as well have tried to stop a tornado. Jumbo eluded them without the least trouble, but their efforts to keep out of range of his flying hoofs were not so easy. Some of them had narrow escapes from being seriously injured.

Mr. Sparling, attracted by the roars of laughter of the audience and the unusual disturbance, had hurried into the big top, where he stood, at first in amazement, then with a broad grin overspreading his countenance.

Now Jumbo began a race with himself about the arena, following the concourse, now and then sending his heels into the air right over the heads of the spectators of the lower row of seats, sending them scrambling under the seats for protection.

A clown ran out with half a dozen paper covered hoops, which he was holding in readiness for the next bareback act.

He flaunted them in the face of the runaway mule.

Jumbo ducked his head under them and Teddy Tucker’s head went through the paper with a crash, the mule’s heels at that instant being high in the air.
