"Thank you, sir."

"And I'm proud of you," added Mr. Robert King, the winner of the monoplane endurance prize, and the man who had practically adopted Dave into the aviation field.

"I've got something to say as to the matter of pride," spoke up old
Grimshaw. "A lad who can make the run Dashaway did with the Baby
Racer, is a boy to holler about."

"If there's anything to be proud about," added Dave, "it's the right good friends I've made."

"My friends, too," put in the impetuous Hiram. "I'm getting along famously. Why, I only tipped out of the dummy airship once yesterday."

All hands were in fine high spirits. It was several days after the wild night race Dave and Hiram had made to Kewaukee. Now the entire party were on their way to the borders of the lake, where the new hydroplane made by the Interstate Aviation Company was ready for a trial trip. Grimshaw knew little of hydroplanes, and the Interstate people had sent an expert demonstrator to the spot to teach their young exhibitor the ropes. Dave had been constantly under this man's tuition.

It was far more easy, he had learned, to acquire a thorough knowledge, of how to run a hydroplane than to operate a monoplane. It was simpler, and besides that his experience with an airship helped wonderfully.

Dave was winning golden opinions from his employers. The way in which he had dosed the Kewaukee contract had pleased them immensely. There was another end to the Kewaukee episode that had brought heaps of satisfaction to all of them, especially to Hiram Dobbs.

The Baby Racer had been quickly repaired at Kewaukee, and had made a speedy return trip to Columbus. Somehow the story of how the Interstate people had outwitted the plots of the Star crowd had gotten noised around the meet. Then a class journal devoted to aeronautics printed the story.

"Well," Hiram had come to Mr. King's hangar that morning to say, "the Dawson crowd are simply squelched. I met Jerry Dawson and his father. You ought to see the looks they gave me when I just grinned at them, and said 'Contract!' It was like a fellow saying 'Baa!' to sheep. Why, those fellows just sneaked away. We've beaten them at every angle, Dave, and I reckon they'll give up their meanness now, and quickly fade away."
