I'll fly low over Mr. Foger's house, and see if Andy has his airship
there. We'll give him a salute."

Before doing this, however, Tom had picked out a good landing place
in a clearing in the woods, and had arranged some incandescent
lights on high branches of trees. The lights enclosed a square, in
the centre of which the Falcon was to drop down.

Of course it was necessary to descend to do this, to arrange the
storage battery and the clock switch. Then, so as to throw their
enemies off their track, they made landings in several other places,
though they did nothing, merely staying there as a sort of "bluff"
as Ned called it.

"They'll have their own troubles if they investigate every place we
stopped at," remarked Tom, "and, even if they do hit on the one we
have selected for our camp they won't see the lights in the trees,
for they're well hidden."

This work done, they flew back toward Logansville, and sailed over
Andy's house.

"There he is, on the roof, working at his airship!" exclaimed Ned,
as they came within viewing distance, and, surely enough, there was
the bully, tinkering away at his craft. Tom flew low enough down to
speak to him, and, as the Falcon produced no noise, it was not
difficult to make their voices heard.

"Hello, Andy!" called Tom, as he swept slowly overhead.

Andy looked up, but only scowled.

"Nice day; isn't it?" put in Ned.

"You get on away from here!" burst out the bully. "You are
trespassing, by flying over my house, and I could have you arrested
for it. Keep away."

"All right," agreed Tom with a laugh. "Don't trespass by flying over
our ship, Andy. We also might have a gun to shoot searchlights
with," he added.

Andy started, but did not reply, though Tom, who was watching him
closely, thought he saw an expression of fear come over the bully's
face.

"Do you think it was Andy who did the shooting?" asked Ned.

"No, he hasn't the nerve," replied Tom. "I don't know what to think
about that affair last night."

"Excepting that the smugglers are getting afraid of you, and want to
get you out of the way," put in the custom official.

That night, when it was very dark, the Falcon noiselessly made her
way upward and sailed along until she was over the square in the
forest, marked out by the four lights. Then Tom sent her safely
down.

"Now let 'em find us if they can!" the young inventor exclaimed, as he
made the craft fast. "We'll turn in now, and see what happens
