ilt for paying war expenses," grinned Eph. Then his look became more
solemn, as he added:

"But we don't want ever to get into a naval condition where it will be
easy for some other country to snatch that fat pocket-book out of our
hands."

"Let's go along, fellows. Drowning and confusion to all possible foes
afloat," proposed Hal, the one who could never see "war" on the horizon.
"After a winter on hot sodas, it'll be a relief to know that the
druggist put in icecream soda to-day."

So the three boys turned and made their way to the drugstore. While
they were exploring with spoons the bottoms of their glasses, the
street door opened. Herr Professor Radberg looked in, then came in,
beaming condescendingly on the young men.

"Ach! You young men are just the ones I wish to see," he exclaimed,
resting one hand on Eph's shoulder, the other on Hal's.

"Lots of folks will pay for that privilege," declared Eph, solemnly.

"Yes? Well, I will pay, too--you shall see. I shall look for you at
the hotel, in just one hour. One hour--remember."

you're in for bad news."

"Bad news? Ach! What do you mean, young man?"

"Just what I said," replied Eph.

Professor Radberg looked so puzzled that Hal Hastings broke in, quietly:

"Professor, unless I'm much in error, you want to see us about a
proposition that we enter the German naval service."

"Hush! Not so loud," warned Radberg, looking suspiciously around.

"There's nothing we have to keep quiet about," Hal went on. "You have
already spoken to our captain, Jack Benson, about this matter."

"Ach! Yes."

"And Jack has refused."

"Your captain is a fool!" cried the German.

"Then we serve a fool, because he's our captain," retorted Hal, quietly,
though there was a flash in his eyes.

"I shall look for you two at the hotel in one hour," declared the German,
impressively.

"My friend, Mr. Somers, has already told you that you'll be using your
eyesight to poor advantage, then," Hal answered.

"What do you mean?"

"Why, I mean, Professor, that you c
