As if in answer to the lad's question, the "tweetle" of the ringmaster's whistle brought everything to a standstill under the big top. Even the band suddenly ceased playing. Then Phil knew that something worthwhile was coming.

"Ladies and gentlemen!" announced the ringmaster, holding up his right hand to attract the eyes of the spectators to him, "Little Miss Dimples, The Queen of the Sawdust Arena, will now perform her thrilling, death-defying, unexcelled, unequaled feat of turning a somersault on the back of a running horse. I might add in this connection that Little Miss Dimples is the only woman who ever succeeded in going through this feat without finishing up by breaking her neck. The band will cease playing while this perilous performance is on, as the least distraction on the part of the rider might result fatally for her. Ladies and gentlemen, I introduce to you Little Miss Dimples," concluded the ringmaster, with a comprehensive wave of the hand toward the young woman and her gray ring horse.

Dimples dropped to the ring, swept a courtesy to the audience, then leaped to the animal's back with a sharp little "yip! yip!"

During the first round of the ring she removed the bridle, tossing it mischievously in Phil's direction. He caught it deftly, placing it on the ground beside him, then edged a little closer to the ring that he might the better observe her work.

The ring horse started off at a lively gallop, the rider allowing her elbows to rise and fall with the motion of the horse, in order that she might the more thoroughly become a part of the animal itself—that the motion of each should be the same.

Suddenly Dimples sprang nimbly to her feet, tossing her riding whip to the waiting hands of the ringmaster.

Phil half scrambled to his feet as he saw her poise for a backward somersault. He had noted another thing, too. She was going to throw herself, it seemed, just as the horse was on the roughest part of the ring. He wondered if she could make it. To him it was a risky thing to try, but she no doubt knew better than he what she was about.

The ringmaster held up his hand as a signal to the audience that the daring act was about to take place.

Phil crept a little nearer.

All at once the girl gracefully threw herself into the air. He judged she had cleared the back of the animal by at least three feet, a high jump to make straight up with unbent knees.
