"Why, you don't say so, Dashaway?" exclaimed the aviator, much disturbed.

"Those are the orders," replied Dave. "I have hurried back to
Columbus purposely, to consult on your helping in a search for the
Drifter."

"Of course that is not possible, now that this Dale affair has come up," said Mr. King. "As to a search for the stolen aircraft, that is going to be no easy task, I'm thinking. Have the Interstate people no theory as to the way the Drifter was stolen, and the motive for the theft?"

"I had better tell you all I know about it, Mr. King."

"Do so, Dashaway."

Dave proceeded to relate his interview with Mr. Randolph, the manager of the Interstate factory. He did not refer just then to his experience with the tramp.

"It's a good deal of a puzzle," commented the aviator. "What is your plan?"

"Why, I expected that I could induce you to take charge of the search. As you cannot, I am thinking of Hiram going back with me to Bolton."

"What's your idea?"

"The Interstate people have offered me their best monoplane to start the chase for the missing Drifter."
