"Yes. I couldn't catch him. But you'd better go lie down, father. It's getting late, and you look tired."

"I am tired, Tom, and I think I'll go to bed. Have you finished your arrangements with Mr. Gunmore?"

"Well, I guess we've gone as far as we can until I invent the new aeroplane," replied Tom, with a smile.

"Then you'll really enter the meet?" asked the secretary eagerly.

"I think I will," decided Tom. "The prize of ten thousand dollars is worth trying for, and besides that, I'll be glad to get to work again on a speedy craft. Yes, I'll enter the meet."

"Good!" exclaimed Mr. Gunmore, shaking hands with the young inventor. "I didn't have my trip for nothing, then. I'll go back in the morning and report to the committee that I've been successful. I am greatly obliged to you."

He left the Swift home, after refusing Tom's invitation to remain all night, and went to his hotel. Tom then insisted that his father retire.

As for the young inventor, he was not satisfied with the result of his attempt to catch Andy Foger. He had no idea why the bully was hiding under the library window, but Tom surmised that some mischief might be afoot.

"Sam Snedecker or Pete Bailey, the two cronies of Andy, may still be around here, trying to play some trick on me," mused Tom. "I think I'll take a look outside." And taking a stout cane from the umbrella rack, the youth sallied forth into the yard and extensive grounds surrounding his house.

While he is thus looking for possible intruders we will tell you a little more about him than has been possible since the call of the aviation secretary.
