“Yes. The papers have got hold of this wager of dad’s—I think Mr. Damon, in his enthusiasm, spilled the beans—and there is some talk of a national aero club taking the matter up. A paper or two has mentioned that such a trip will greatly advance the science of flying, and there may be a big prize offered for the winner of the race—the one who makes the best actual time around the world.”

“Then you’re likely to win considerable money,” suggested Ned.

“If the plans are carried out, yes. But I’ll be satisfied to win that twenty thousand dollars for dad. It will just about make me come out with an even break.”

“An even break?”

“Yes. This machine will cost me around twenty thousand,” said Tom. “Of course, I’ll be out my expenses, but then dad got me into this thing unthinkingly and I’m going to see it through. But if some one offers a prize and I can win it, I’ll have that much velvet.”

“It’s a bigger thing than I thought,” Ned stated. “I hope you won’t be disappointed in your craft, Tom. I mean I hope it will work.”

“It will work—I’m sure of that,” said the young inventor. “Of course whether I can eat up the miles and actually get around the world in twenty days remains to be seen. But I’m going to try!”

The two were at the workshop now. It was shrouded in darkness, for the day’s labor was over.

“Stand still a minute until I turn on the lights,” Tom said, as he opened a little side door and stepped in, leaving Ned to follow. “It’s as dark as a pocket in here.”

Ned could hear Tom fumbling for the electric switch. Then, just as the light was turned on, there came, from the other side of the big shop and back of the Air Monarch, a clicking sound followed by a scream of pain.
