w necessary it was for the matter
to be looked into secretly. Mr. Lavine had promised to give a motor boat
to whichever club found the sunken _Bright Eyes_ and the silver
images. And the Busters must not know a thing about it until they were
sure----

"Then Mr. Lavine believes father's story about the boat?" burst in
Polly.

"I believe he does, Polly, dear. I think, Polly, that he would be very,
very glad to have Mr. Jarley cleared of all suspicion. He is sorry for
your father's trouble. I think his attitude, toward your father has
changed from what it must have been at one time."

"It ought to be!" exclaimed Polly.

"Of course. But we none of us always do all we ought to do," observed
Wyn mildly.

"If we are going to try and find that place where you dived to-day, Wyn,
we'd better be about it," Polly urged.

"You'll go now?" cried Wyn.

"Of course I will. The boys will be asleep up in their camp. We will
take the _Coquette_. There is a breeze."

"Let's tow my canoe behind, then," said Wyn, eagerly. "Come on! I'm just
crazy to dive for the thing again. If it _is_ the _Bright
Eyes_----"

Polly insisted upon hunting out a couple of old blankets to wrap about
them if the wind should turn chill.

"And after you have been overboard you'll want something to protect you
from the night air," she said.

"Oh, Polly! do you suppose I can find the place again?" cried Wyn,

"You say it's right off the boys' float? Well! we can look, I guess."

"Feel, you mean," laughed Wyn. "For _I_ couldn't see anything down
there even by daylight--it was so deep."

"All right. We'll look with our hands. I shall know if it's a boat, Wyn,
once I reach it."

"And I hope it _is_" gasped Wyn. "Not alone for _your_ sake,
Polly. Why, if it is the _Bright Eyes_, the Go-Aheads will own a
motor boat their very own selves. Won't that be fine?"

But Polly was too busy getting the catboat ready to answer. The
_Coquette_ was moored just a little way off the landing, and the
two girls went out to her in Wyn's canoe.

There was a lantern in her cuddy and Polly lit it. Then they slipped the
buoyed moorings and spread a little canvas. There was quite a breeze,
and it was fair for their course to Gannet Island. Soon the catboat was
laying over a bit, and the foam was streaking away behind them in a
broad wake.

"What a lovely night!" sighed Wyn. "And it will be the very gladdest
night I eve
