The boys watched the swiftly approaching boat. It came in through the
narrows at top speed, circled around toward the docks, and passed the
catboat at a distance.

"'S. P. 888'!" yelled Torry. "Look there!"

"I thought it was that same chaser we saw before," Frenchy said.

"Wonder what she wants in here at Seacove?" Ikey asked.

Whistler had changed their course to bring the catboat nearer to the
naval boat, which was slowing down. Torry leaped upon the low-decked
cabin and began signaling by the semaphore code. In his blue uniform
his body stood out clearly against the catboat's sail, and he was at
once observed by the crew of the S. P. 888.

"Whew! Look at that!" gasped Frenchy. "They are answering."

Then he and Ikey began to spell out the word that the seaman on the deck
of the chaser was signaling in the same code Torrance had used.

"M-O-R-G-A-N!"

"Oi, oi!" yelled Ikey. "They're after you, Whistler!"

"What's the next?" gasped Frenchy.

Another name was not long in coming.
