e shunned,
hereafter, if not destroyed, by those who have worked with me."

"I shall do my best to get you safely away from Spruce Beach," promised
Jack Benson. "Have you more to say to me, Mademoiselle?"

"Nothing, but good-bye, my Captain."

She held out her hand. Once more Jack took it, bending low over it.
Tears shone in her eyes, but Jack did not see them, for he turned,
going back to his friends.

Not until they were well away from the parlor did Jack Benson offer any
account of the interview that had just taken place.

"Let me have that envelope, then," requested Jacob Farnum, gravely.

"What are you going to do with it, sir?" Jack asked, as he passed it
over.

"Do with it?" repeated his employer. "I'm going to take it to the
nearest druggist, and find out what the stuff is."

"We'd better take this latest news to our friend Trotter," suggested
David Pollard.

"By all means," nodded Farnum. "And I'll meet the rest of you there."

The little house wherein the Secret Service, men had taken up their
headquarters was not far away. When the inventor and the submarine boys
rang the bell Mr. Packwood admitted them.

"Step right into the next room," advised Mr. Packwood. "You'll find some
one there you know."

A the submarine folks entered the room they saw Trotter seated at a
table on which were writing materials. At the other side of the table
standing very erect, and in a very respectful pose, was the Japanese,
Kamanako.

CONCLUSION

"Good evening, honorable gentlemen," said the Japanese, turning when he
heard the new arrivals entering.

"Mr. Kamanako is going to leave us," announced Trotter, with a smile.
"He goes north to-night. Here is the slip of paper, my boy, that will
take you past any meddlesome inquiry. But it is good only until
midnight, so I advise you to be sure to catch to-night's express."

"I shall, and thank you, honorable sir," replied the Japanese, bowing.

"Then I won't detain you any longer, or you may miss your train."

Once more the Japanese bowed, then turned to Captain Jack Benson.

"Honorable Captain," he said, "I had pleasure to show you something
about jiu-jitsu. You did me honor to show me most excellent thing
you called American strategy. I shall not forget it."

With bows to the others Kamanako quickly took his leave.

"We had nothing very strong on which we could hold that fellow, so we
had to let him go," declared Mr. Trotter,
