"Yes, probably we could win," admitted the young inventor,
"but we are going to try for a better prize."

"A better one? I don't understand."

"Sunken treasure," explained Tom. "There's a ship sunk off
the coast of Uruguay, with three hundred thousand dollars in
gold bullion aboard. Dad and I are going to try to recover
that in our submarine. We're going to start day after
to-morrow, and, if you like, you may go along."

"Go along! Of course I'll go along!" cried the eccentric
man. "But I never heard of such a thing. Sunken treasure!
Three hundred thousand dollars in gold! My, what a lot of
money! And to go after it in a submarine! It's as good as a
story!"

"Yes, we hope to recover all the treasure," said the lad.
"We ought to be able to claim at least half of it."

"Bless my pocketbook!" cried Mr. Damon, but Tom did not
hear him. At that instant his attention was attracted by
seeing two men emerge from behind the sand dune near which
he and Mr. Damon had halted momentarily, when the youth
explained about the treasure. The man looked sharply at Tom.
A moment later the first man was joined by another, and at
the sight of him our hero could not repress an exclamation
of alarm. For the second man was none other than Addison
Berg.
