"Look here, you've been turning it over your mind, then?" asked his cousin.
"Sure I have," grinned Andy, promptly. "Never could bear to let anything puzzle me long. Used to lie awake half the night trying to clinch a name that had just slipped a cog in my memory."
"All right. Suppose you give us the benefit of what you decided might be the answer to this problem. Who are these two men, Andy?"
"You know they admit being well up in aviation?" the other remarked as a preliminary.
"So Larry and Elephant said," Frank replied.
"And that not only had they attended many meets but admitted being well acquainted with a lot of people whose names we see in the papers every day—men who have done things along the line of aviation. Get that, Frank?"
"I have. Now go on with your answer," nodded the other, encouragingly.
"These gentlemen have been sent up here for a purpose! Perhaps they are in the pay of some unscrupulous manufacturer of aeroplanes, who would not be above stealing the ideas of two boys, and applying them to his up-to-date machines, placed on the market, and for sale to the public!"
"Gosh!" exclaimed Elephant.
"That sounds all to the good to me!" remarked Larry; while Nat tried to express himself intelligently along similar lines; but being suddenly seized with one of his spasms, was obliged to take it out in numerous mouthings, and a working of his facial muscles, all the while making unintelligible sounds.
