While I still lingered over this very improving and intellectual employment, my thoughts insensibly began to wander. The moonlight shining into the room reminded me of a certain moonlight night in England--the night after a picnic party in a Welsh valley. Every incident of the drive homeward, through lovely scenery, which the moonlight made lovelier than ever, came back to my remembrance, though I had never given the picnic a thought for years; though, if I had _tried_ to recollect it, I could certainly have recalled little or nothing of that scene long past. Of all the wonderful faculties that help to tell us we are immortal, which speaks the sublime truth more eloquently than memory? Here was I, in a strange house of the most suspicious character, in a situation of uncertainty, and even of peril, which might seem to make the cool exercise of my recollection almost out of the question; nevertheless, remembering, quite involuntarily, places, people, conversations, minute circumstances of every kind, which I had thought forgotten forever; which I could not possibly have recalled at will, even under the most favorable auspices. And what cause had produced in a moment the whole of this strange, complicated, mysterious effect? Nothing but some rays of moonlight shining in at my bedroom window. I was still thinking of the picnic--of our merriment on the drive home--of the sentimental young lady who _would_ quote “Childe Harold” because it was moonlight. I was absorbed by these past scenes and past amusements, when, in an instant, the thread on which my memories hung snapped asunder; my attention immediately came back to present things more vividly than ever, and I found myself, I neither knew why nor wherefore, looking hard at the picture again. Looking for what? Good God! the man had pulled his hat down on his brows! No! the hat itself was gone! Where was the conical crown? Where the feathers--three white, two green? Not there! In place of the hat and feathers, what dusky object was it that now hid his forehead, his eyes, his shading hand? Was the bed moving? I turned on my back and looked up. Was I mad? drunk? dreaming? giddy again? or was the top of the bed really moving down--sinking slowly, regularly, silently, horribly, right down throughout the whole of its length and breadth--right down upon me, as I lay underneath? My blood seemed to stand still. A deadly paralysing coldness stole all over me as I turned my head round on the pillow and determined to test whether the bed-top was really moving or not, by keeping my eye on the man in the picture. The next look in that direction was enough. The dull, black, frowzy outline of the valance above me was within an inch of being parallel with his waist. I still looked breathlessly. And steadily and slowly--very slowly--I saw the figure, and the line of frame below the figure, vanish, as the valance moved down before it.
