twice a day to see that this regulation was carried out. If
a pupil was lax in any particular regarding his room, he was given a
demerit in consequence thereof.

"Well, thank goodness! he didn't upset anything, even if he was here,"
murmured Fred to himself. "I wonder what the little imp was up to?"
Then a sudden thought struck him and he walked to the clothes closet in
the bottom of which he had deposited his suitcase. He found the bag in
the closet, but it was placed there in such a way that he was sure it
had been handled.

"Well, what have you found?" questioned Andy, who had followed his
cousin to the room.

"I think I know why he came here," declared Fred. "More than likely
Martell sent him here to find out whether I really had the suitcase or
not. The bag I know has been handled. When I placed it in the closet I
put the open end of the straps against the wall. Now the open ends are
on this side."

"Say! you're some detective, Fred!"

"I know how I left the bag. And he certainly had it out of the closet
and put it back."

"See if he did anything to it," went on Andy, quickly; and thereupon
Fred brought the bag forth and examined it. It was empty, just as he
had left it.

"Well, that will take the worry of the missing bag from Martell's
mind," was Fred's comment, as he and Andy left the room, this time
locking the door.

"Martell must have had some kind of a clue to the truth or he wouldn't
have sent Codfish here," was Andy's comment. "Maybe he got on to what
part Walt Baxter and Ned Lowe played in the trick." And in this surmise
Andy was correct. By the merest accident Codfish had overheard Walt and
Ned speaking about the joke, and at once he had gone to Nappy with the
news; and the upshot had been that Nappy had sent the sneak to Fred's
room to learn if the suitcase with Fred's initials upon it was there.

Late that afternoon both the old and the new cadets were assigned to
their places in the various classrooms and also given the text-books
which they were to study during the term.

"This begins to look like work," sighed Randy.

"Well, we didn't come here just for the fun of it," declared Jack. "We
came here, if you'll remember, to get an education."

"Oh, I'm not going to complain," returned his cousin quickly. "I'm
willing to do my share of studying. But after the splendid vacation we
had this Summer it will be a little tough at the beginning to get down
to the grind."

"That's just what I
