"I'll go--if I can pursuade my wife to let me," said the odd man in a whisper, as if, even then, the good lady might overhear him. "I'm not going to say anything about giants. I'll tell her we are going to rescue a poor fellow from--er--well from the natives of South America, and I'm sure she'll consent. Of course I'll go."

"That's three," remarked Tom. "I think I can get Eradicate to go. He doesn't like airships, and when he knows we're not going in one it will please him. Then he likes it hot, and I guess South America is about as warm as they come. I am almost sure we can count on Rad."

"That will make a nice party," commented the circus man. "Now I'll make out a list of the supplies you'd better take, and tell you what to do about getting native helpers, and so on," and with that he plunged into the midst of details that took up most of the remainder of the day.

"Well, then I guess that settles most everything," remarked Tom, several hours later. "I'll begin at once to take the Lark apart for shipment, and begin ordering the things we need."

"Oh, there's one thing I almost forgot about," said Mr. Preston suddenly. "Queer, how I should overlook that, too. I don't suppose you mind a fight or two; do you?" he asked, looking sharply at Tom.

"Well, it all depends. We've had several fights on other expeditions, though I can't say that I like 'em," replied the young inventor. "Why do you ask?"

"Because you may have one--or several," was the answer of the circus man. "You'll have to beware of my rival."

"Your rival?"

"Yes, the bitterest foe I have is a rival circus man named Wayland Waydell. He, or some of his men, are always camping on my trail when I send out after a new consignment of wild animals, and I shouldn't be a bit surprised but what he'd try to get ahead of me on the giant game."

"But how does he know you want giants?" asked Tom.
