"Well," remarked Mr. Sharp, when Tom and Mr. Damon had called on him, to state that Andy Foger's machine was now on the grounds, and demanding to be allowed to view it, to see if it was an infringement on the one entered by the young inventor, "I'll do the best I can for you. I'll lay the case before the committee. It will meet at once, and I'll let you know what they say."

"Understand," said Tom, "I don't want to interfere unless I am convinced that Andy is trying an underhand trick. My plans are missing, and I think he took them. If his machine is made after those plans, it is, obviously, a steal, and I want him ruled out of the meet."

"And so he shall be!" exclaimed Mr. Sharp. "Get the evidence against him, and we'll act quickly enough."

The committee met in about an hour, and considered the case. Meanwhile, Tom and Mr. Damon strolled past the tent with its flaring sign. There was a man on guard, but Andy was not in sight.

Then Tom was sent for, and Mr. Sharp told him what conclusion had been arrived at. It was this:

"Under the rules of the meet," said the balloonist, "we had to guarantee privacy to all the contestants until such time as they choose to exhibit their machines. That is, they need not bring them out until just before the races," he added. "This is not a handicap affair, and the speediest machine, or the one that goes to the greatest height, according to which class it enters, will win. In consequence we cannot force any contestant to declare what kind of a machine he will use until he gets ready.

"Some are going to use the familiar type of biplanes and, as you can see, there is no secret about them. They are trying them out now." This was so, for several machines of this type were either in the air, circling about, or were being run over the ground.

"But others," continued Mr. Sharp, "will not even take the committee into their confidence until just before the race. They want to keep their craft a secret. We can't compel them to do otherwise. I'm sorry, Tom, but the only thing I see for you to do is to wait until the last minute. Then, if you find Andy has infringed on your machine, lodge a protest—that is unless you can get evidence against him before that time."

Tom well knew the uselessness of the latter plan. He and Mr. Damon had tried several times to get a glimpse of the craft Andy had made, but without success. As to the other alternative—that of waiting until the last moment—Tom feared that, too, would be futile.

"For," he reasoned, "just before the race there will be a lot of confusion, officials will be here and there, scattered over the ground, they will be hard to find, and it will be almost useless to protest then. Andy will enter the race, and there is a possibility that he may win. Almost any one could with a machine like the Humming-Bird. It's the machine almost as much as the operator, in a case like this."
