"Eph, see that light? Commander Ennerling is sure it belongs to a Naval vessel. We're going to try to tie up to her while she's going at cruising speed."

"Say, that's like you!" burst from Eph Somers, an admiring grin showing in his face.

"Eph, have you sufficient nerve to get into your bathing suit like lightning, and go overboard with a lantern and a rocket or two, with only a state-room door to float on?"

"Of course," nodded Eph. "The sea's not rough, and a state-room door is big enough to ride on. But you're not going to leave me marooned, are you?"

"Not likely," laughed Jack. "You're right in the path of the approaching vessel, Eph, and they'll see your rockets and lantern. They'll pick you up."

Eph's face went suddenly solemn.

"Say," he muttered, "I'll have a real interesting time trying to make some sort of an explanation, won't I? What shall I tell them if they do pick me up?"

"Tell 'em anything you like, except that the 'Pollard' is trying to tie up," responded Jack.

"That all?" demanded Eph, with a grin. "If it is, I'm off to get into my traveling clothes."

"Hurry," nodded Jack. "Send Hal up to the wheel, while I explain the whole thing to Mr. Farnum. But, commander, what if that shouldn't be a Navy vessel?"
