"Here?" asked Frank. "Here to this club-room? The boys won't do a
thing to him if he puts on dog!"

"Is he a submarine expert?" asked Frank.

"Sure!" replied Jack. "He wouldn't be sent here to post us if he
wasn't, would he?"

"I don't believe he knows any more about a submarine, right now, than
Ned does," Jimmie exclaimed. "Ned's been taking walks on the bottom of
the Bay every mornin' for a week!"

Jack and Frank turned to Ned with amazement showing on their faces.

"Have you, Ned?" they asked, in chorus.

"Have you been out training without letting us know about it?"

"You bet he has!" Jimmie grinned. "I've been with him most of the time
too. This Captain Moore, whoever he is, hain't got nothin' on Ned when
it comes to makin' the wheels go round under the water."

"Oh, you!" laughed Jack, pointing a finger at Jimmie. "You can't run a
submarine, even if Ned can."

"You wait an' see!" retorted the boy, indignantly. "You wait until we
get into the Chinese sea, then you'll see what I know about boats that
travel on ocean beds!"

"Can he run a submarine, Ned?" asked Jack.
