"That's so, and now that we know Andy is rebuilding his old airship, maybe we'd better tell him."
"Tell who?"
"That government agent. Tell him he's wrong in thinking that Andy is out of the game. We might send him word that we just learned that Andy is getting active again. He has as much right to suspect and question him, as he had you."
"Oh, I don't know," began Tom slowly. He was not a vindicative youth, nor, for that matter, was Ned. And Tom would not go out of his way to give information about an enemy, when it was not certain that the said enemy meant anything wrong. "I don't believe there's anything in it," finished our hero. "Andy may have a lot of time on his hands, and, for want of something better to do, he's fixing up his aeroplane."
"Look!" suddenly exclaimed Ned. "There's that agent now! He's going to the depot to get a train, I guess," and he pointed to the government man, who had so lately interviewed Tom. "I'm going to speak to him!" impulsively declared Ned.
"I wouldn't," objected Tom, but his chum had already hastened on ahead, and soon was seen talking excitedly to Mr. Whitford. Tom sauntered up in time to hear the close of the conversation.
"I'm much obliged to you for your information," said the custom officer, "but I'm afraid, just as you say your chum felt about it, that there's nothing in it. This Foger chap may have been bad in the past, but I hardly think he's in with the smugglers. What I'm looking for is not a lad who has one airship, but someone who is making a lot of them, and supplying the men who are running goods over the border. That's the sort of game I'm after, and if this Andy Foger only has one aeroplane I hardly think he can be very dangerous."
"Well, perhaps not," admitted Ned. "But I thought I'd tell you."
"And I'm glad you did. If you hear anything more, I'll be glad to have you let me know. Here's my card," and thanking the boys for their interest Mr. Whitford passed on.
Tom and Ned gave the noiseless airship a test the next day. The craft, which was the stanch Falcon, remodeled, was run out of the shed, Koku the giant helping, while Mr. Swift stood looking on, an interested spectator of what his son was about to do. Eradicate, the old colored man, who was driving his mule Boomerang, hitched to a wagon in which he was carting away some refuse that had been raked up in the garden, halted his outfit nearby.
