I now became aware that something interposed between the page and the light--the page was overshadowed; I looked up, and I saw what I shall find it very difficult, perhaps impossible, to describe. It was a darkness shaping itself forth from the air in very undefined outline. I cannot say it was of a human form, and yet it had more resemblance to a human form, or rather shadow, than to anything else. As it stood, wholly apart and distinct from the air and the light around it, its dimensions seemed gigantic, the summit nearly touching the ceiling. While I gazed, a feeling of intense cold seized me. An iceberg before me could not more have chilled me; nor could the cold of an iceberg have been more purely physical. I feel convinced that it was not the cold caused by fear. As I continued to gaze, I thought--but this I cannot say with precision--that I distinguished two eyes looking down on me from the height. One moment I fancied that I distinguished them clearly, the next they seemed gone; but still two rays of a pale-blue light frequently shot through the darkness, as from the height on which I half-believed, half-doubted, that I had encountered the eyes. I strove to speak--my voice utterly failed me; I could only think to myself: "Is this fear? it is not fear!" I strove to rise--in vain; I felt as if weighed down by an irresistible force. Indeed, my impression was that of an immense and overwhelming power opposed to my volition--that sense of utter inadequacy to cope with a force beyond man's, which one may feel physically in a storm at sea, in a conflagration, or when confronting some terrible wild beast, or rather, perhaps, the shark of the ocean, I felt morally. Opposed to my will was another will, as far superior to its strength as storm, fire, and shark are superior in material force to the force of man. And now, as this impression grew on me--now came, at last, horror--horror to a degree that no words can convey. Still I retained pride, if not courage; and in my own mind I said: "This is horror, but it is not fear; unless I fear I cannot be harmed; my reason rejects this thing; it is an illusion--I do not fear." With a violent effort I succeeded at last in stretching out my hand toward the weapon on the table: as I did so, on the arm and shoulder I received a strange shock, and my arm fell to my side powerless. And now, to add to my horror, the light began slowly to wane from the candles--they were not, as it were, extinguished, but their flame seemed very gradually withdrawn; it was the same with the fire--the light was extracted from the fuel; in a few minutes the room was in utter darkness. The dread that came over me, to be thus in the dark with that dark Thing, whose power was so intensely felt, brought a reaction of nerve. In fact,
