These last orders were to the two machinists whom Andy had engaged to help him, and the bully gave himself no end of airs and importance as he bustled about.

Tom could not help but admit that Andy's machine was a big affair. There was a great stretch of wings and planes, several rudders other appliances for which the young inventor could not exactly fathom a use. He did not think the machine would fly far, if at all. But Andy was hurrying here and there, getting the triplane in place on a level stretch of ground, as if he intended to capture some great prize.

"Are you going to tackle him about stealing a copy of that map?" asked Ned.

"I will if I get a chance," answered Tom, in a low voice.

He got his opportunity a few minutes later. Andy, hurrying here and there, came face to face with the young inventor.

"Hello, Andy," spoke Tom, good-naturedly. "So you're going to make a flight, eh?"

"Yes, I am, and I s'pose you came around to see if you could get any ideas; didn't you?" sneered Andy.

"Of course," admitted Tom, with an easy laugh. "My airship doesn't fly, you know, Andy, and I want to see what's wrong with it."

There was a laugh in the crowd, at this, for Tom's success was well known.

"Are you going to Alaska?" suddenly asked Tom, in a low voice, of the bully.
