The Library room, in which I was reading, is a large, lofty hall, fitted with dark bookcases, heavy and huge as if for giants, singularly perfect in point of inconvenience and inaccessibility, and good only in that they bore a certain architectural proportion to the great height and expanse of the dark room. My desk was so placed that my back was toward the entrance, which was the balustraded opening, in the Library floor, of a wide staircase; and close at my side and before me were racks with muskets and spears, cases of curiosities, and other appurtenances of the room. It being now past the middle of the night, when sleep is heaviest, the stillness was perfect. My two shaded lamps made a small sphere of dusky yellow light, which I felt to be surrounded and, as it were, compressed by the thick darkness, which I could easily fancy to be something tangible and heavy, settling noiselessly down from beneath the lofty arches of the roof. The ancient penmanship and curious contents of the faded pages before me carried my thoughts backward into the old Colonial times, with their rigid social distinctions, lofty manners, and ill-concealed superstition; and I mused upon grim old magistrates, wizened witches, stately dames, rugged Indian-fighters, and all their strange doings and sayings in the ancient days, until, between drowsiness and imagining, I fell into a tangled labyrinth of romance, history, and reverie. Then all at once I seemed half to awake, and fell into one of those fits of foolish nervous apprehension to which many even of the coolest and bravest are liable in deep solitude and darkness,--and if they, how much more an excitable person like myself! My heart throbbed for no reason, and, sitting with my head bowed down upon my hands, I fancied the most impossible dangers,--of men taking aim at me with the antique firearms out of the far dark corners, or casting heavy weights upon me through the skylight overhead. How easily, I fancied, could it happen. Did not the cellar-door open just now? I half arose, almost frightened. I believe I should have taken an old rapier and a light and gone to look, but for very shame. And besides, there were two thick floors between me and the door, and that itself was set in the heavy wall between the cellar of this wing of the building and that under its main body; so that if it had been opened, I could not have heard it. Accordingly I resumed my posture and my painful intense musing. But now I could have almost sworn that I heard soft steps coming up the staircase, and whispers floating upon the air of the great solitary room:--_I did!_ But not soon enough. At the sound of a distinct, heavy footstep behind me, I sprang up and turned about, but only to find myself pinioned by one of the arms of a rough-looking, vicious-faced man, who pressed his other hand tightly over my mouth. A confederate was busy at the case of coins.
