self. But, really,
how do I know that you have such authority from your own side of the
water?"

Radberg looked a bit puzzled, for a moment. Then, as he seemed to
begin to comprehend, he replied, heavily:

"Herr Benson, I have already told you that I am Herr Professor--"

"Now, don't hang out the striped pole again, please," urged Jack, his
face as sober as that of a judge. "Come right down to the points of
the compass. How am I to know that you really do represent the
German government?"

"Ach! I comprehend," nodded the German. "Of course you will understand
that, on an errand of this kind, I do not travel with too many papers.
But I shall take you and your two companions on to Washington to-morrow,
I think--"

"To-morrow ought to do as well as any time," replied Jack, ironically.

"Yes; I think it will be to-morrow," continued the German. "I shall
take you to our German Embassy, and one of our officials there will
prove to you that I have been acting with authority."

wider open. When was it all settled, sir?"

"Why, did you not tell me--"

"Haven't had a blessed chance to tell you anything," replied Jack,
looking astonished. "You've been doing all the telling."

"But you'll go with me, of course, to Washington?" uttered Radberg,
looking much taken aback.

"I doubt it," muttered young Benson, shaking his head. "In fact, sir,
I may as well tell you that it's waste of our time to carry this line
of talk any further."

"Ach! You are cunning," smiled Professor Radberg, no longer nonplussed.
"That is as it should be, too, for you are a clever young man, Herr
Benson."

"A thousand thanks," murmured Captain Jack.

"But, instead of talk," pursued the German, "you wish to see some money.
Quite right! I should, were I in your place, Herr Benso
