“It paid; didn’t it?” intimated Mr. Brackett, with a wave of his hand towards the new machine and its pilot.

“I should say it did!” cried the impetuous young airman. “Oh, how did you ever bring it all about?”

“Through one of the friends you and Dashaway seem to have the faculty of gaining everywhere you go,” answered the manufacturer.

“Was Dave shut up bad—or long?”

“No. Within twenty-four hours of his capture he was at our plant and has been practicing every day since. As to the old Ariel—what do you think of Ariel II?”

Hiram was satisfied for the present with the brief explanation made. In his own mind he could readily reason out that Borden had, in some way, been instrumental in the escape of Dave.

“They’re getting ready,” broke in Bruce. He was bubbling over with excitement and exultation. Mr. Brackett had led them to a section in the rows just back of the big stand. He had seated himself comfortably, but his two young guests were unable to keep still, and stood up and moved about, buoyant and expectant.

“Plain sailing,” announced some one from the next section, reading the programme, and a smile of satisfaction showed on the face of the big aeroplane manufacturer.

There were twelve entries for this number, for it was a free-for-all, purposely allowed to give air craft builders a chance to show their machines. Hiram and Bruce had eyes only for Dave and the new Ariel. It left the ground at the signal, smoothly and promptly.

“Self-starter,” spoke the complacent manufacturer to his young allies. “For grace, lightness and accuracy we back this, our latest machine, against the world.”
