“That’s pretty poor, I guess!” he shouted.

“What is it?” asked Ben.

“Looks to me like the papers stolen from Colleton’s office!”

The aviator took the papers into his hand and examined them intently for a moment. Then he turned to Jimmie with a smile.

“You’re right!” he said. “These are the papers described in my instructions! And they’re all here—every one!”

“Look here!” chuckled Jimmie. “If some guy should come down to New York some day and steal the Singer building, and you should be sent out to find it, and should get into a submarine and dive down to the bottom of the China sea, you’d find the Singer building right there waiting for us to come and get it!”

“That’s the kind of luck we’ve had in this case!” admitted Mr. Havens.

“Luck?” repeated Jimmie. “There ain’t any luck about it! We’ve just loafed around camp, and taken joy-rides in flying machines, and the other fellows have brought all the goods to us.”

“It strikes me,” Mr. Havens suggested, “that we ought to get rid of Mr. DuBois and his hand-bag just about as soon as possible. I have no doubt that the fellows over in the other camp recognized the hand-bag lost by the man in brown.”

“And that means that they’ll knock DuBois’ head off if they get a chance!” Jimmie cut in.
