“Do you know how to make ’em?”

“Not yet,” answered Andy all aglow, “but the man who carved that propeller can build anything he wants. I’ve got a book about ’em—‘How to Construct and Operate an Aeroplane.’”

Perplexity shone on the captain’s face.

“Who’ll fly it?” he asked.

Andy smiled, and then slowly winked an eye.

“But your mother?” added the captain.

“That’s it,” answered the boy meaningly. “You’re goin’ to make the machine; it’s goin’ to belong to you—which it will. You’ll have to hire me to help. Why not? We’ll settle the flyin’ business when we get to it. How about it?” he concluded appealingly.

His companion shook his head.

“We’d need a lot of things we haven’t got—or I would,” and he grinned.
