An attendant discovered what was going on and started on a run for Phil, who brought his whip down on the flanks of the ring horse again and again, driving the animal straight at the attendant. The result was that the fellow was bowled over in a twinkling. The horse cleared the man at a bound.

At this the audience roared. They saw that something unusual was taking place, though they did not understand what it all meant.

Half a dozen men ran toward Phil, while Sully himself was charging down the concourse as fast as he could go, roaring out his commands at the top of his powerful voice.

"Get a horse and follow him!" he shouted. "Run back and send one of the men out around the tent to head him off! He's running away with my best ring horse!"

Phil swept through the exit, bowling over two men who were standing there on guard, and nearly running down a group of boys who were standing just outside trying to get a glimpse into the tent.

As he gained the outer air he heard the hoof beats of a running horse bearing down on him from the left side of the big top.

The Circus Boy knew what that meant. They were after him already.
