This elicited a broad grin from the acrobat. "Look here, kid," he said, "do you know how long it took me to learn the business?" "I don't know, but I should like to know." "Three years." "No doubt you can do a great deal more than I." "Oh, no, certainly not!" said the acrobat, ironically. "I see you don't believe me," said Kit. "I'll tell you what you remind me of, kid. There was a fellow came to our circus last summer, and wanted to get an engagement as rider. He said he'd been a cowboy out in New Mexico, and had been employed to break horses. So we gave the fellow a trial. We brought out a wild mustang, and told him to show what he could do. The mustang let him get on, as was his custom, but after he was fairly on, he gave a jump, and Mr. Cowboy measured his length on the sawdust." Kit and Dan both smiled at this story. "I am not a cowboy, and don't profess to ride bucking mustangs," he said, "though my friend Dan may." "I'd rather be excused," put in Dan. "I'll tell you what, kid, if you'll go through the performance you've just seen I'll give you five dollars." The fellow expected Kit would make some hasty excuse, but he was mistaken. Our hero rose from his seat, removed his coat and vest, and bounded into the arena. "I am ready," he said, "but I am not strong enough to be the under man. I'll do the other." "All right! Go ahead!" The speaker put himself in position. Kit gave a spring, and in an instant was upon his shoulders. There was an exclamation of surprise from the second acrobat. "Christopher!" he exclaimed. "The boy's got something in him, after all." "Now what shall I do?" asked Kit, as with folded arms he stood on the acrobat's shoulders. "Keep your place while I walk round the arena." Kit maintained his position while the acrobat ran round the circle, increasing his pace on purpose to dislodge his young associate. But Kit was too well used to this act to be embarrassed. He held himself erect, and never swerved for an instant. "Pretty good, kid!" said the acrobat. "Now reverse yourself and stand on my hands with your feet in the air." Kit made the change skillfully, and to the equal surprise of Dan and the other acrobat, both of whom applauded without stint. "Can you do anything else?" asked Alonzo Vincenti. "Yes." Kit went through a variety of other feats, and then descending from his elevated perch, was about to resume his coat and vest, when the circus performer asked him, "Can you tumble?" Kit's answer was to roll over the arena in a succession of somersaults and hand springs. "Well, I'm beat!" said the acrobat. "You're the smartest kid I ever met in my travels. Are you sure you're not a professional?" "Quite sure," answered Kit, smiling. "You never traveled with a show, then?" Kit shook his head. "Where on earth did you pick up all these acts?" "I took lessons of Professor Donaldson." "You did! Well, that explains it. I say, kid, you ought to join a circus. You'd command a fine salary."
