"I know how to fall," Joe declared, and, though he spoke positively, he was not in the least boastful. "Here, I'll show you," he went on.

Their act was not quite finished, but before going on with the next gymnastic feat Joe caught hold of a hoisting rope that ran through a pulley, and, at a nodded signal, one of the ring-men hauled the lad up to the top of the tent to the little platform where Joe had stood when taking his place on the high trapeze.

Joe signaled to the ring-master that he was going to make a jump into the net from that height, and at once the crowd again became aware that something unusual was going on. It was a jump seldom made, at least in The Sampson Brothers' Circus. The platform was fully twenty feet higher than the trapeze from which Joe and his fellow-performer had dropped a few minutes before. And, as Sid Lascalla had said, there was a risk even in jumping into a life net. But Joe Strong seemed to know what he was about.

"Say, he's going to do some jump!" exclaimed Benny Turton, who came into the ring at that moment, dressed in his shimmering, scaly suit, ready to do his "human fish" act.

"That's what!" cried Jim Tracy. "Give him the long roll and the boom!" he called to the leader of the musicians.

As Joe poised for his jump the snare drummer rattled out a "ruffle," and as it started Joe leaned forward and leaped.

Down he went, for a few feet, as straight as an arrow. Then he suddenly doubled up into a sort of ball, and began turning over and over. The crowd held its breath. The drum continued to rattle out its thundering accompaniment. How many somersaults Joe turned none of the spectators reckoned, but the youthful performer kept count of them, for he wanted to "straighten out," to land on his feet in the net.

"He'll never do it!" predicted Tonzo Lascalla.

And it did begin to look as though Joe had miscalculated.

But no. Just before he reached the springy life net he straightened out and came down feet first, bouncing up, and down like a rubber ball. The instant he landed the bass drum gave forth a thundering "boom," and as Joe rose, and came down again, the drummer punctuated each descent with a bang, until the crowd that had applauded madly at the jump was laughing at the queer effect of Joe's bouncing to the accompaniment of the drum.
