After she had thus thought for some two hours, gaining more and more self-command every moment, as she turned and returned all the points of her situation in her own mind, and viewed them in every different aspect, she rose to retire to rest, lay down, and tried to sleep. At first importunate thought troubled her. The same kind of ideas went on--the same reasonings upon them--and slumber for more than one hour would not visit her eyelids. But she was a very resolute woman, and at length she determined that she would not think: she would banish thought altogether; she would not let the mind rest for one moment upon any subject whatsoever; and she succeeded. The absence of thought is sleep; and she slept; but resolution ended where sleep begun, and the images she had banished waking, returned to the mind in slumber. Her rest was troubled. Growing fancies seemed to come thick upon her mind; though the eyes remained closed, the features were agitated; the lips moved. Sometimes she laughed; sometimes she moaned piteously; sometimes tears found their way through her closed eyelids; and sobs struggled in her bosom. At length, between three and four o'clock in the morning, Mrs. Hazleton rose up in bed. She opened her eyes, too; but there was a dull glassy look about them--a fixed leaden stare, not natural to her waking hours. Slowly she got out of bed, approached the table, took up a candle which she had left burning there, and which was now nearly down to the socket, and walked straight to the door, saying aloud, "Very dark--very dark--every thing is dark." She tried the door, but found it locked; and the constable slept on. She then returned to the table, seated herself, and for some five or ten minutes continued to twist her long hair round her fingers. She then rose again, and went straight to the window, threw it up, and seemed to look out. "Chilly--chilly," she said. "I must walk to warm myself." The sill of the window was somewhat high, but that was no obstacle; for there was a chair near, and Mrs. Hazleton placed it for herself with as much care as if she had been wide awake. When this was done she stepped lightly upon it, and put her knee upon the window-sill, raised herself suddenly upright, and struck her head sharply against the upper part of the window. It is probable that the blow woke her, but at all events it destroyed her balance, and she fell forward at once out of the window. There was a loud shriek, and then a deep groan. But the constable slept on, and no one knew the fate that had befallen her 'till Mr. Short, the surgeon, passing the house, was attracted to the spot where she had fallen, by a moan, and the sight of a white object lying beneath the window.
