ey can't prove it," cried Nappy, quickly. "That is, they
won't be able to do it unless you or Codfish give me away."

"You know me well enough to know I won't say a word, Nappy. And as for
Codfish, just give him to understand if he opens his trap you'll fix
him for it."

A little while later Martell and Brown went below. In the lower hallway
they met Fred and some of the others.

"Well, Martell, when are you going to return that suitcase?" demanded
the youngest Rover.

"I told you I haven't got your suitcase and don't know anything about
it," cried the loudly dressed youth. But at the same time his face grew
flushed and he could not look Fred in the eyes.

"You took that suitcase, and if you don't return it pretty quick you'll
see what will happen," warned Fred; and then he walked away with his
cousins, leaving Nappy Martell gazing at Slugger Brown, questioningly.
The pair conversed in a low tone, and passed on out of the hall on to
the campus.

"Now's your time, Fred, if you're going to do as you said," whispered
Randy.

"Right you are!" was the quick reply. "Come on;" and Fred led the way
upstairs again, his cousins following.

When they reached Nappy Martell's room, they found the door locked. But
the door to Slugger Brown's apartment was unfastened, and they quickly
entered this and passed into the room beyond.

"Say, Jack, won't you stand on guard?" questioned Fred. "They might
come back while we're at work."

"All right, boys. But be careful what you do. You don't want to spoil
anything. A joke is a joke, but it loses its flavor if it is carried
too far."

With Jack standing in the hallway on guard, Fred and the twins took
possession of Nappy Martell's room. The boy who loved to dress so
loudly was rather methodical in his habits, and had arranged all of his
clothing and other articles with great nicety in his chiffonier and his
closet.

"The bed first," whispered Fred; and in a trice the boys had taken off
the bed clothing and turned up the mattress. On the springs they placed
one of the bedsheets and on the top of this they distributed all of
Nappy's choice neckties and also his fancy-colored socks. Then to this
they added his cuffs, his fancy underwear, and all of his loose
jewelry. The articles were spread over the bed with care, so that they
rested as flat as possible.

"Now, we'll put the mattress back and then make up the bed as nicely as
possible," said Randy, who, of course, in a joke of
