"I don't know about that. Most of the girls' things were brand new and probably could be sold again at a fairly good price."

"I still think it's a practical joke," insisted Nan. She rose lazily and went over to one of the dresser mirrors where she critically inspected her reflection. "Dear me, look at that streak of dirt across my nose! I look a sight!"

"I don't think it's a practical joke." Jo could not be shaken from the subject. "A girl might open one locker just to be funny. But she wouldn't be apt to go about opening them wholesale. That would be silly, because it would only get her into heaps of trouble."

"It probably will—if Miss Jane finds her out." Nan was as persistent in her theory as Jo was in hers. "I certainly would hate to be that girl!"

There was the sound of footsteps and laughter in the hall outside.

The next moment the door burst open and three girls entered the room. One was Jessie Robinson, another Doris Maybel. The third was as yet unknown to the chums.

"Here's a fine row," said Jessie without preface. "Miss Jane is bound to find the girl or girls who played that practical joke, and there isn't a girl in the school but what suspects every other girl of being the guilty one. A fine time we're going to have at Laurel Hall for the next few days, I can see that!"

At this point the impulsive girl appeared to realize that new friends and old had not, as yet, been properly introduced and promptly set herself to correct the error.

"This is Doris Maybel," she said. "We room together, although our room isn't anywhere near as nice as this. And this," thrusting forward the third of the trio, "is Gladys Holt—a nice girl if you don't cross her——"

"Then she's cross," said Doris, and they all laughed together at the feeble joke.
