The following morning the boys spent with Captain Brice watching him as he worked on his motor and helping whenever they could.

“That’s a Liberty isn’t it?” Jade had asked as soon as he saw it.

“Yes.”

“And we’re pretty sure that that fellow has a liberty also.”

“And you’re wondering if I’m going to be able to catch him?”

Jack blushed.

“Well, you see, sir, I—” he began when the captain interrupted.

“Sure I see, but you see I’ve got a new type of carburetor here which is the only one ever made because I made it myself and so far it has given this old buss nearly fifty per cent. more speed than she had before, and she could give any of them a good run before I made the change.”

At noon they met Captain Jim at the hotel and they had dinner together.

Captain Jim announced that he had the warrants for the arrest of the men all in shape and Captain Brice said that he would easily be able to finish with the plane on Monday.
