s. Littell's door. That
lady hurriedly admitted them, her motherly mind instantly picturing
something wrong.

"It's Libbie," said Betty softly. "Bob saw her from his window in the
garden and he thinks she's walking in her sleep. We don't want to
frighten her. What can we do?"

"I'll be right out," said Mrs. Littell reassuringly. "Libbie's mother
used to walk in her sleep, too. I think I can get the child into bed
without waking her at all."

In a few moments she came out, a heavy corduroy robe and slippers
protecting her against the night air.

"Esther, lamb, you stay here in the hall with Bob," she directed her
youngest daughter. "You won't be afraid with Bob, will you, dear? I don't
want too many to go down or we may startle Libbie."

Betty crept downstairs after Mrs. Littell, the soft, thick rugs making
their progress absolutely noiseless. Not a step in the well-built
staircase creaked.

They found the chain and bolt drawn from the heavy front door. Libbie had
evidently let herself out with no difficulty. From the wide hall window
Bob and Esther watched breathlessly.

Mrs. Littell did not speak, but took one of the limp hands in hers, and
Betty took the other. Libbie made no resistance, and allowed them to
draw her toward the house. They crossed the threshold, led her upstairs,
past the quivering Esther and Bob huddled on the windowseat, and into the
bedroom she had so unceremoniously left.

Then Mrs. Littell lifted her in strong arms, put her gently down on the
bed, and Libbie rolled up like a little kitten, tucked one hand under her
cheek and continued to sleep.

"Now go to bed, children, do," commanded Mrs. Littell. "Bob, I'm so
thankful you saw that child--she might have wandered off or caught a
severe cold. As it is, I don't believe she has been out very long. What's
the matter, Esther?"

"Can I come and sleep with you?" pleaded Esther. "I'm afraid to sleep
with Libbie. She might do it again."

"I don't think so--not to-night," said her mother, smiling. "However,
