It was not easy; why did I eat that lettuce salad at Père Garceau's? I should have known better. It was making me irresistibly sleepy, and wakefulness was absolutely necessary. It was certainly gratifying to know that I could sleep, that my courage was by me to that extent, but in the interests of science I must keep awake. But almost never, it seemed, had sleep looked so desirable. Half a hundred times, nearly, I would doze for an instant, only to awake with a start, and find my pipe gone out. Nor did the exertion of relighting it pull me together. I struck my match mechanically, and with the first puff dropped off again. It was most vexing. I got up and walked around the room. It was most annoying. My cramped position had almost put both my legs to sleep. I could hardly stand. I felt numb, as though with cold. There was no longer any sound from the other rooms, nor from without. I sank down in my window seat. How dark it was growing! I turned up the lantern. That pipe again, how obstinately it kept going out! and my last match was gone. The lantern, too, was _that_ going out? I lifted my hand to turn it up again. It felt like lead, and fell beside me. _Then_ I awoke,--absolutely. I remembered the story of "The Haunters and the Haunted." _This_ was the Horror. I tried to rise, to cry out. My body was like lead, my tongue was paralyzed. I could hardly move my eyes. And the light was going out. There was no question about that. Darker and darker yet; little by little the pattern of the paper was swallowed up in the advancing night. A prickling numbness gathered in every nerve, my right arm slipped without feeling from my lap to my side, and I could not raise it,--it swung helpless. A thin, keen humming began in my head, like the cicadas on a hillside in September. The darkness was coming fast. Yes, this was it. Something was subjecting me, body and mind, to slow paralysis. Physically I was already dead. If I could only hold my mind, my consciousness, I might still be safe, but could I? Could I resist the mad horror of this silence, the deepening dark, the creeping numbness? I knew that, like the man in the ghost story, my only safety lay here. It had come at last. My body was dead, I could no longer move my eyes. They were fixed in that last look on the place where the door had been, now only a deepening of the dark. Utter night: the last flicker of the lantern was gone. I sat and waited; my mind was still keen, but how long would it last? There was a limit even to the endurance of the utter panic of fear.
