“Perhaps. You never can tell. It is according to who is on watch to-night. We never know whose duty it is. Miss Crouch is perfectly sneaking——”

“Oh, Molly!”

“Yes, she is. She wears sneaks when she is on guard, and she often opens our doors and looks in. And if you lock your door she is likely to rap on it and wake you up. Says she wants to be sure you are all right.”

“Are we supposed to leave our doors unlocked?” Beth asked.

“Why, you can do as you please. But if Miss Crouch feels like looking into your room in the middle of the night, she’ll get you up to open the door. She’s a suspicious creature.”

“For no reason, I suppose?” laughed Beth.

“Never mind!” Then Molly’s voice dropped to a whisper: “I’ll show you how to fool Miss Crouch.”

“What about?” asked Beth.

“If she should feel it necessary to look in while we are gone—see here!”

Molly rolled the extra blanket which lay upon the foot of Beth’s bed into the semblance of a human figure and put it under the bedclothes. There it looked like a person asleep, wrapped head and heels in the coverings. Then she made the same masquerade in her own bed.
