we could make a landing close up to the fires. There seems
to be a little bay there."

"Thank you," said Jack in a tone of relief. "We'll run close in and try
to find out what's the matter. Maybe the stranger can help us get our
bearings. Lucky the fog lifted when it did or we would have piled up
high and dry on this beach!"

As the Fortuna approached the little bight indicated by Tom, they
discovered that there would be plenty of water to enable the Fortuna to
run close inshore and permit of their landing easily. Tom and Harry
busied themselves with clearing away one of the metal boats carried on
the cabin roof and preparing to lower it when the Fortuna should come to
rest. Upon completing their task, Tom stood up for another view of the
beach which they were approaching.

"Look, Jack!" he cried. "Can you see the boy over there wig-wagging at
us? Isn't that the Boy Scout wig-wag?"

"Sure enough, it is!" declared Jack excitedly. "Take this flag and
answer him. You're in a good place up there."

He passed the flag up to Tom as he spoke. All four lads watched with

"He's going to use the Semaphore code, then!" declared Jack.

"There it comes!" cried Harry. "He's calling us! Answer him."

"All right, Scout!" assented Tom. "Here comes the message!"

from the body--that's 'N.' Oh, he's telling us his name--Dan! Hurray!
He's introducing himself!"

"Here comes the rest," cried Harry excitedly, "both arms diagonally
downward and to the left--that's 'G.' Now the right down in front and
left diagonally up and out from the shoulder--that's 'E.' Next both arms
out horizontally from the body--that's 'R.' Why, that spells 'DANGER!'
What does that mean?"

"Search me!" declared Tom. "I'm not a bit surprised, though for we've
been in danger ever since we left Mobile. Anything goes here. I'd thank
him to tell us some news, though."

"Well, here comes some more!" announced Jack who had shut off the power,
permitting the Fortuna to ride the smooth waters of the little bight
without headway.

"Here's some more!" cried Arnold, who has again take
