secrets," retorted the young submarine captain.

"You will hold tongue better, if you please," snapped Kamanako.

"I? Hold my tongue for any scamp like you?" taunted Jack Benson.

The taunt had the effect for which Jack wished. Kamanako, looking
furious, dropped his dress suit case and ran angrily forward.

Just in time, as the Japanese bounded through the fringe of weeds,
Captain Jack dodged adroitly to one side.

So Kamanako plunged past him--and, the next instant, there came a
smothered yell from the inside of the well shaft.

"Oh, that was a shame!" came indignantly, from one of the women in the
party of strangers.

But Jack, paying no heed to her, had stepped back to the edge of the
well shaft. Dimly, down at the bottom, he could make out Kamanako,
standing in slimy water that reached nearly up to his arm-pits.

"Is the water fine, eh?" Jack called down, laughingly.

"I show you--some time!" came the answer, in smothered rage.

"You showed me Japanese jiu-jitsu," mocked Benson "so I had to do
something to return your courtesy. What I have just shown you is
called--American strategy!"
