"'Waking suddenly in the night always gives me a strange sensation. I feel as though some one must have called me, and, involuntarily, I listen for a second summons. This night I listened as usual, and distinctly heard a step in the hall. Our door stood partly open, but the darkness was intense. At first I thought it might be a member of the family in search of something in the upper story, for there were several unoccupied rooms and a medicine-closet opening into the hall; but, after a moment, I noticed that the step did not pause or enter these chambers, but seemed to keep in the hall, going back and forth, from one end to the other, with perfect regularity and steadiness. Much perplexed, I gently awakened Kate, and, placing my hand over her lips, I whispered in her ear, 'listen!' She obeyed, and, with beating hearts, we heard the footstep pacing back and forth before our door, now at the west end, now at the east, in a measured gait to which we could almost beat time, so regularly came the sound. The hall was carpeted, and the footfalls soft, yet not as though the unseen visitor was trying to deaden the sound. It was a natural step. From the light tread we might have supposed it to be a woman's foot, but from the stride it was more like a man. I do not know how long we lay there motionless. I felt myself growing more and more nervous, and Kate's hand, as it pressed mine, was cold and trembling. I think we would have been relieved if the step had paused, or even entered our room; that, at least, would have been like an ordinary burglar. But this steady march, to and fro, seemed so unaccountable. If the steps, too, had been soft and muffled, if we could have supposed the person was creeping about after booty of some kind, we should have been frightened, no doubt, but not so appalled as we were now at this singular, easy, and apparently aimless promenade. We did not speak, but lay trembling, and scarcely daring to breathe. Our room was long, and the distance to the open door so great that we could not hope to reach it unnoticed in the darkness, before the step would be upon us again. Besides, the lock was out of order, so that even if we could have summoned courage to shut it, it could not be fastened. The stairway, too, was at such a distance beyond our door, that we did not dare to try that way of escape, bringing us, as it would, face to face with our unseen visitor. There was nothing left but silent endurance, and thus we lay counting the footsteps through the long hours. We could not hope, either, that the other members of the family would be aroused, as their sleeping-rooms were not directly below us, but beyond, in the wings. The clock struck two, and half-past, and steadily the step kept on its regular sound, passing and repassing our door. It grew insupportable. It seemed as though I should not be able to keep from shrieking aloud each time it drew near. If we could have
