"Then come back to the hotel with me."

"You are a foreigner, aren't you?" asked Jack, surveying the stranger coolly.

"I am German," replied Radberg, in a tone of surprise.

"I thought so," nodded the boy. "That is, I didn't know from what country you came. But, in this country, when we ask a favor of a stranger, we usually say 'please.'"

"I am Herr Professor—"

"Oh, barbers are just as polite as other folks," Jack assured him, his laughing eyes resting on the somewhat bewildered-looking face of the German.

"Then please, Herr Benson, come back to the hotel with me."

"Yes; if it's really necessary. But why do you want to go to the hotel?"

"Because, Herr Benson, when we are there, I shall have much of importance to say to you."

"Important to me, or to you?" asked Jack, thoughtfully.
