"Then don't do it," returned Mr. Rhinds, sympathetically. "Just wait until we get alongside, and you'll see your young men popping out of the conning tower, rested and as bright as new buttons."

A moment later the shore boat rounded in alongside. Then, quite suddenly, the three submarine boys projected themselves through the manhole, and stood in full view on the platform deck.

"Eh? Hey?" gasped John C. Rhinds, utterly nonplussed.

Fred Radwin's lower jaw seemed to drop several inches. He stared as though he were seeing ghosts, while a sickly, greenish pallor crept into his handsome face.

"By Jove, you were right, Rhinds!" gasped Jacob Farnum, turning. "Thank you, old man, for keeping our courage up."

"Good morning, Mr. Farnum! Good Morning Mr. Pollard!" chorused the three submarine boys. Then, favoring Rhinds and Radwin with brief glances:

"Good morning—gentlemen!"

"Gentlemen?" repeated Eph, disgustedly, under his breath. "I think not!"

Though Rhinds and his agent speedily managed to look pleasant, they hadn't gotten their spirits back when the shore boat pulled away.

Farnum and Pollard went hurriedly below, where Jack and his comrades followed.
