this boy came up to Sam and Tom.

"We had a cadet here yesterday who was awfully mad," said the boy.

"Had hydrophobia, eh?" returned Tom. "Too bad!"

"No, I don't mean that; I mean he was very angry."

"What was the trouble?"

"I don't know exactly, but I think he had been sent away from the
school for something or other."

"What was his name?"

"Lew Flapp."

"Why, I thought he had gone home!" cried Sam.

"So did I," answered his brother. He turned to the hotel youth. "What
was this Flapp doing here?"

"Nothing much. He asked the boss when you were expected here."

"Is he here now?"

"No, he left last night."

"Where did he go to?"

"I don't know, but I thought I would tell you about the fellow. I think
he is going to try to do you cadets some harm."

"Did he mention any names?"

"He seemed to be extra bitter against three brothers named Rover."

"Humph!"

"Are the Rovers here?" went on the youth.

"I think they are, sonny. I'm one, this is another, and there is the
third," and Tom pointed to Dick, who was at a distance, conversing with
some other cadets.

"Oh, so you are the Rovers! How strange that I should speak to you of
this!"

"Which way did this Lew Flapp go?" questioned Sam.
"Off the way you are bound."

"I'll wager he tries to make trouble for us on our way to Putnam Hall,
Tom."

"It's not unlikely, Sam."

"Shall we tell Captain Putnam of this?" Tom shook his head.

"No, let us tell Dick, though, and a few of the others. Then we can
keep our eyes peeled for Lew Flapp and, if he actually does wrong,
expose him."

A little later Tom and Sam interviewed Dick on the subject, and then
they told Larry Colby, Fred Garrison, George Granbury, and half a dozen
others.

"I don't believe he will do much," said Larry Colby. "He is only
talking, that's all. He knows well enough that Captain Putnam can have
him locked up, if he wants to."

By eight o'clock that evening the field in which they were to encamp
for the night was reached. Tents were speedily put up, and half a dozen
camp-fires started, making the boys feel quite at home. The cadets
gathered around the fires and sang song after song, and not a few
practical jokes were played.

"Hans, they tell me you feel cold and want your blood shook up," said
Tom to Hans Mueller, the German cadet.

"Coldt, is it?" queried Hans. "Vot you dinks, I vos coldt mid der
borometer apout two hundred by der shade, ain't it? I vos so hot like I
