"Do you really think he is going to have a try for the government prize?" asked Larry Dexter.

"Well, stranger things have happened," admitted the young millionaire.

"You're not worrying, though, are you?" asked Paul.

"Not a bit. I imagine I'll have to compete with more formidable opponents than Uncle Ezra. But I do give Larson credit for knowing a lot about aircraft. I don't believe, though, that his mercury stabilizers are reliable. Still he may have made improvements on them. I'd like to get a look at Uncle Ezra's machine."

"And he doesn't want you to," laughed Innis. "He's a queer man, keeping track of every cent."

"Oh, it wouldn't be Uncle Ezra if he didn't do that," returned Dick, with a grin.

There were busy days ahead for the young millionaire and his chums. Though the Abaris seemed to have been in almost perfect trim on her trial trip, it developed that several changes had to be made in her. Not important ones, but small ones, on which the success, or failure, of the prize journey might depend.

Dick and his friends worked early and late to make the aircraft as nearly perfect as possible.

Dick's entry had been formally accepted by the government, and he had been told that an army officer would be assigned to make the trans-continental flight with him, to report officially on the time and performance of the craft. For the government desired to establish the nearest perfect form of aeroplane, and it reserved the right to purchase the patent of the successful model.

"And it is on that point that more money may be made than by merely winning the prize," said Mr. Vardon. "We must not forget that, so we want everything as nearly right as possible."
