"You will never do it," said Sid, and there was a queer look on his face as he glanced at Tonzo. The other seemed to wink, just the mere fraction of a wink, and then, like a flash, it came to Joe. "He doesn't want me to do it," thought our hero. "Tonzo wants me to fail. He doesn't want me to be successful, for he thinks maybe he can get Sim back. But I'll fool him! I think he has been drawing up his legs the instant I jumped for them, so I would miss. I'll watch next time." This Joe did, and found his surmise right. Just before he reached with outstretched hands for Tonzo's legs, the man drew them slightly up, and, as a result, Joe missed. "Here's where I turn a trick on him," mused the young performer, as he failed and landed in the net In his next attempt Joe leaped unusually high, and though Tonzo drew up his legs he could not pull them beyond Joe's reach. "That's the time I did it!" cried Joe, as he made the catch and swung to and fro. Sid, on the ground below, shrugged his shoulders, and said something to Tonzo in Spanish. CHAPTER VIII HELEN'S LETTER "Now I wonder," mused Joe as he leaped out of the net, "what they said to each other. I'm sure it was about me. Well, let it go. I did the trick, and I guess he won't pull his legs away again. If he does he'll have to pull 'em so far that it will be noticed all over, and he can't say it was an accident. I'll take care to make a high jump." Joe practised the trick again and again, until he felt he was perfect in it. Tonzo seemed to have given up the idea of spoiling it, if that had been his intention, and he and Joe worked at it until they could do it smoothly. "When are you going to put it on?" Jim Tracy inquired, when told there was a new feature to the Lascalla Brothers' act. "Oh, in a couple of nights now," Joe answered. "You sure are making good, all right," the ring-master informed him. "I didn't make any mistake booking you. I didn't know whom to turn to in a hurry when Sim Dobley went back on me, and then I happened to think of you. Got your route from one of the magazines, and sent you the wire." "I was mighty glad to come," confessed Joe. The new act created more applause than ever for the Lascalla Brothers when it was exhibited, but the louder applause seemed to come to Joe, though he did not try to keep his fellow performers from their share. And, as might be expected, there was not a little professional jealousy on the part of some of the other performers. If Sid and Tonzo were jealous of him they took pains to hide that fact from Joe, but some of the others were not so careful. A few of the other gymnasts openly declared that the Lascalla Brothers were getting altogether too much public attention.
