e much of a clew after all. Print isn't like
handwriting for evidence."

"And to think they sailed right over this place, and we weren't
home," mourned Tom. "It makes me mad!"

But there was no use in regretting what had happened, and, after a
hot breakfast in the airship, with Mr. Damon presiding at the
electrical stove, they all felt more hopeful. Mr. Whitford left for
his office, promising to send word to Tom as to whether or not Andy
was abroad in the airship during the night.

"I wonder if that 'Committee of Three' is Andy and these two fellows
with him in the airship?" asked Ned.

"Hard telling," responded his chum. "Now for a good sleep. Koku,
keep the crowd away while we have a rest," for the giant had
indulged in a good rest while the airship was on patrol during the
night.

Not so much of a crowd came out as on the first day, and Koku had
little trouble in keeping them far enough away so that Tom and the
others could get some rest. Koku walked about, brandishing a big
club, and looking as fierce as a giant in a fairy tale. It was
afternoon when a message came from Mr. Whitford to the effect that
Andy's airship was not out the previous night, and that so far no
clews had developed from the letter, or from any other source.

"We'll just have to keep our eyes open," wrote Mr. Whitford. "I
think perhaps we are altogether wrong about the Fogers, unless they
are deeper than I give them credit for. It might be well to let the
smugglers think you are frightened, and go away for a day or so,
selecting a more secluded spot to remain in. That may cause them to
get bolder, and we may catch them unawares."

"That's a good plan. I'll try it," decided Tom. "We'll move to-morrow
to a new location."

"Why not to-night?" asked Ned.

"Because it's getting late, and I want to circle about in daylight
and pick out a good place. Morning will do all right."

"Then you're not going out to-night?"

"No. Mr. Whitford writes that as goods were smuggled over last night
it will hardly be likely that they will repeat the trick to-night.
We'll have a little rest."

"Going to mount guard?" asked Ned.

"No, I don't think so. No one will disturb us."

Afterward the young inventor wished that he had kept a better watch
that night, for it nearly proved disastrous for him.

It must have been about midnight that Tom was awakened by a movement
in the airship.

"Who's that?" he asked suddenly.

"Koku," came the reassuring re
