The cots in the sleeping tents were placed on wooden platforms raised three or four inches from the ground, and on clear nights the sides of the tents were rolled up. Laura, too interested and excited to sleep at once, lay in her cot looking out across the open space now flooded with light from the late-risen moon, and thought of the girls sleeping around her. Herself an only child, she had a great desire—almost a passion—for girls; girls who were lonely like herself—girls who had to struggle with ill-health, poverty, and hard work as she did not.

Suddenly she started up in bed, her eyes wide with half-startled surprise. Reaching over to the adjoining cot, she touched her friend, whispering, “Anne, Anne, look!” and as Anne opened drowsy eyes, Laura pointed to the moonlit space.

Anne stared for a moment, then she laughed softly and whispered back, “It’s a ghost dance, Laura. Some of those irrepressible girls couldn’t resist this moonlight. They’re doing an Indian folk dance.”

“Isn’t it weird—in the moonlight and in utter silence!” Laura said under her breath. “I should think somebody would giggle and spoil the effect.”

“That would be a signal for Mrs. Royall to ‘discover’ them and send them back to bed,” Anne returned. “So long as they do it in utter silence so as to disturb no one else, the Guardians wink at it. It is pretty, isn’t it?”

“Lovely!”

Anne turned over and went to sleep again, but Laura watched the slender graceful figures in their loose white garments till suddenly they melted into the shadows and were gone. Then she too slept till a shaft of sunlight, touching her eyelids, awakened her to a new day. She looked across at her friend, who smiled back at her. “I feel so well and so happy!” she exclaimed.

“It is sleeping in the open air,” Anne replied. “Almost everybody wakes happy here—except the Problem.”

“The Problem?” Laura echoed.

“I mean Olga Priest, the girl you asked about last night. We Guardians call her the Problem because no one has yet been able to do anything for her.”
