till I find out who did it!" And then William Philander began to
moan once more over the burrs. It was a good quarter of an hour before
he had his cot cleaned off and fit to use once more, and even then he
was so excited and nervous he could not sleep another wink.

"William Philander won't forget his last night with the boys in a
hurry," remarked Tom, as he slipped off to bed once more.

"You had better keep quiet over this," came from Dick. "We don't want
to spoil our records for the term, remember."

"Right you are, Dick. I'll be as mum as a clam climbing a huckleberry
bush."

The boys were tired out over the march of the afternoon and over
playing the joke on Tubbs, and it was not long before all of the Rovers
were sound asleep. The three brothers had begged for permission to tent
together and this had been allowed by Captain Putnam, for the term was
virtually over, ending with the dismissal of the cadets at the last
encampment parade.

On guard duty at one end of the field was a cadet named Link Smith, a
rather weak-minded fellow who was easily led by those who cared to

Lew Flapp and his evil associates, but fortunately for the
feeble-minded cadet he had been called home during the time when Lew
Flapp got into the trouble which ended by his dismissal from Putnam Hall.

Link Smith was pacing up and down sleepily when he heard a peculiar

repeated.

"The old call," he murmured to himself. At first he did not feel like
answering, but presently did so. Then from out of the gloom stalked a
tall young fellow, dressed in the uniform of a cadet but with a face
that was strangely painted and powdered.

"Who is it?" questioned Link Smith, uneasily.

"Don't you know me, Link?"

"Lew Flapp!" cried the weak-minded cadet.

"Hush, not so loud, Link. Somebody might hear you."

"What do you want?"

"I want to visit the camp," answered Lew Flapp.

CHAPTER IV

WHAT THE MORNING BROUGHT FORTH

Link Smith was much surprised by Lew Flapp's assertion that he wanted
to visit the camp during the middle of the night and when practically
everybody was asleep.

"What do you want to come in for?" he asked, feeling fairly certain
that Flapp's mission could not be as upright and honest as desired.

"Oh, it's all right, Link," answered the big bully, smoothly.

"But what do you
