urled, almost over the spot
where Wyn and Polly were sure the lost motor boat lay!

"Oh, dear me!" cried Bess. "Now we can't have any fun on the raft. Those
men will be in our way. What do you suppose they are poking around there
in the water with those poles for?"

Wyn began to paddle fast. She shot ahead of the other girls and aimed
directly for the bit of beach on which the boys' canoes were drawn.

The noise and laughter up at the camp assured her that Tubby had arrived
and that all the Busters were at home. Wyn had made up her mind quickly
that, if she must, she would rather take the boys into her confidence
about the sunken boat than let those bateau men find it.

"Boys! Dave!" she hailed them from the water.

Young Shepard appeared at once and, seeing Wyn, ran down to the shore.

"Will you help us?" gasped Wyn. "Quick! get the boys! Move your diving
float where I tell you; those men will find it first, if you don't."

"Find what?" demanded Dave. "Are you sensible, Wynnie?"

The explanation tumbled out of Wyn Mallory's lips then in rather a
jumbled fashion; but Dave understood. He turned and gave the view-halloa
for his mates. They all tumbled down the bank save Tubby.

"Get a move on, fellows," commanded the leader of the Busters. "We've
got to move that raft. Wyn will tell us where. And later we'll tell you
_why_. But the word is now: Look sharp!"

CHAPTER XXVII

IS IT THE "BRIGHT EYES"?

With a whirl and clash of paddles the little flotilla of canoes shot out
to the diving float. The bateau was only a few yards away. The two
rough-looking men in her were sounding the lake bottom, with long poles;
but as yet they had not got around to the right spot.

Wyn breathlessly told the boys to move the raft to the place to which
she paddled. The other girls were excitedly asking questions but neither
Wyn nor Dave answered.

The captain of the Go-Aheads thought that if the raft could be held
stationary--anchored in some way--directly over the sunken boat, the
prize would be safe until Mr. Jarley, or somebody else in authority,
came to claim the _Bright Eyes_. Of course, providing this sunken
boat was she.

Polly had seemed so positive, and so eager to get her father started
after the motor boat he had lost, that Wyn could not understand why the
Jarleys were not already on the spot.

"Hey, there! what are you boys doing?" demanded one of the bateau men,
hailing Dave and his friends on the raft.
