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." "Tell me about her," Laura begged, as, dropping the sides of the tent, Anne began to dress. "Wait till we are outside--there are too many sharp young ears about us here," Anne cautioned. "There'll be time for a walk or a row before breakfast and we can talk then." "Good--let's have a walk," Laura said, and made quick work of her dressing. "Now tell me about the Problem," she urged, when they were seated on a rocky point overlooking the blue waters of the bay. "Poor Olga," Anne said. "I wonder sometimes if she has ever had a really happy day in the eighteen years of her life. Her mother was a Russian of good family and well educated. She married an American who made life bitter for her until he drank himself to death. There were three children older than Olga--two sons who went to the bad, following their father's example. The older girl married a worthless fellow and disappeared, and there was no one left but Olga to support the sick mother and herself, and Olga was only thirteen then! She supported them, somehow, but of course she had to leave her mother alone all day, and one night when she went home she found her gone. She had died all alone." "_O!_" cried Laura.
