When the moon was shining brightly into the room, these performances of Miss Glenn’s were only annoying, but when the nights were very dark, and nothing could be seen in the room, it was really horrible to hear this strange girl chattering and mumbling, now in one corner, now in another, sometimes in the closet, sometimes under the beds; and one night, in a fearful thunder-storm, she seemed to be terribly excited, and when the lightning flashed upon the walls, the shadow of her figure could be seen strangely exaggerated, performing all manner of wild antics. This conduct of Miss Glenn’s puzzled Agnes exceedingly: she could not decide in her own mind whether the girl was trying to frighten them, whether she was asleep, or whether she had turns of derangement at night. Neither of these suppositions seemed exactly to account for her singular actions. Her evident, and, Agnes doubted not, real distress, at the possibility of Mrs. Arlington being informed of her nocturnal performances, and the sacrifices of every kind that she was willing to make to ensure silence, convinced Agnes that it was not done merely to alarm them; her vivid remembrance of all that she had said or done in the night, and her answering questions, and coming to bed so readily when addressed by Agnes, without any appearance of waking up, led her to suppose it was not somnambulism; and as Miss Glenn never showed any sign of wandering of mind in the day time, Agnes could not suppose it to be derangement. Miss Glenn was a perfect enigma; night after night disturbing her room-mates with her strange performances, and every morning going over the same scene of earnest expostulation and entreaty, accompanied by violent weeping, to induce them not to betray her to Mrs. Arlington. Poor little Carrie and Ella kept the secret bravely, though, on the night of the thunder-storm, they were so terrified by Miss Glenn’s conduct, that, wrapping themselves in the bed-blankets, and persuading Agnes to lock the door after them, they went out, and sat upon the stairs till morning. The very next day, two sisters who slept in another room received tidings of the death of their mother, which hurried them home; and as they were not to return that quarter, little Carrie and Ella, with Agnes to intercede for them, requested to be allowed to take their vacated place. Mrs. Arlington readily acquiesced, as, she said, it would be much better to have four in each room. Thus things went on, till, one night, Agnes was horror-stricken to find that Miss Glenn was endeavoring to climb out of the window. As I have said, they were in the third story of the building; and the distance to the ground being very great, the unfortunate girl would inevitably have been dashed to pieces upon the flag stones below, had not Agnes suddenly caught her, and, with a strength that astonished herself, succeeded in drawing her back into the room.
