n. Well,
then--ach! Look at this."

Thrusting a fat hand down deep in a trousers pocket, Herr Professor
Radberg brought up into view a big roll of money. He held this up so
that the submarine boy could feast his eyes on it. Jack looked,
composedly.

"Did you ever see anything like this--you, who are such a young boy?"
smiled the German, teasingly.

"I--I don't know, really," responded Jack, thoughtfully, thrusting a
hand down into his own trousers pocket. Young Benson brought up into
the light a very comfortable looking handful of banknotes, rolled and
surrounded by a broad elastic band. "Let's measure the two, Professor,
and see how they compare."

"Ach!" muttered the German, regarding Jack's money with some displeasure.
"Where did you get all that?"

"Oh, now, Professor!" cried the young submarine captain, reproachfully.
"I didn't ask you where you got yours!"

"Ach! This is all so much foolishness!" cried the German Professor,
returning his money to his pocket.

"That's what I think, too," agreed Jack, following suit. "It's what our
English cousins call 'bad form,' to go to comparing piles of money."

"Now, sit down, Herr Benson, and I will tell you what a very handsome
sum of money, and what excellent wages, the German government will pay
you to enter our imperial naval service."

"How much money is there in Germany?" interrupted the submarine boy,
thoughtfully.

"How much, in all Germany?" demanded the Professor. "Nein! How should

"You expect me, of course, to turn my back on this country for good, to
tell you Germans whatever I may know about submarine secrets, to drill
with your navy, and be prepared to fight in your navy if war comes?"

"Ach, yes! of course," replied Radberg. "Now, we are beginning to
understand one another."

"Professor," interrupted Captain Jack Benson, "we've had enough of
joking."

"Joking? I assure you--"

"Professor," once more broke in the submarine boy, "_I wouldn't sell out
my country's flag for all the money you ever saw!_"

For a few moments the Professor's face was a study in consternation.
Then he broke forth, angrily:

"Ach! You are a fool!"

"I guess so," nodded Jack, without resentment. "That's just the kind
of fools we Americans are generally."

Herr Radberg was a good enough reader of human faces to realize that,
at all events, there was no use in continuing the conversation at
present.

"Very good," he growled. "You can go
