A few minutes, thinking thus, I paced up and down. Then, glancing casually for'ard, along the port side, I leaped like a startled deer and in a blind madness of terror rushed aft along the poop, heading for the cabin. Gone was all my arrogance of youth and my intellectual calm. I had seen a ghost. There, in the dim light, where we had flung the dead man overboard, I had seen a faint and wavering form. Six-feet in length it was, slender, and of substance so attenuated that I had distinctly seen through it the tracery of the fore-rigging. As for me, I was as panic-stricken as a frightened horse. I, as I, had ceased to exist. Through me were vibrating the fibre-instincts of ten thousand generations of superstitious forebears who had been afraid of the dark and the things of the dark. I was not I. I was, in truth, those ten thousand forebears. I was the race, the whole human race, in its superstitious infancy. Not until part way down the cabin-companionway did my identity return to me. I checked my flight and clung to the steep ladder, suffocating, trembling, and dizzy. Never, before nor since, have I had such a shock. I clung to the ladder and considered. I could not doubt my senses. That I had seen something there was no discussion. But what was it? Either a ghost or a joke. There could be nothing else. If a ghost, the question was: would it appear again? If it did not, and I aroused the ship's officers, I would make myself the laughing stock of all on board. And by the same token, if it were a joke, my position would be still more ridiculous. If I were to retain my hard-won place of equality, it would never do to arouse any one until I ascertained the nature of the thing. I am a brave man. I dare to say so; for in fear and trembling I crept up the companion-way and went back to the spot from which I had first seen the thing. It had vanished. My bravery was qualified, however. Though I could see nothing, I was afraid to go for'ard to the spot where I had seen the thing. I resumed my pacing up and down, and though I cast many an anxious glance toward the dread spot, nothing manifested itself. As my equanimity returned to me, I concluded that the whole affair had been a trick of the imagination and that I had got what I deserved for allowing my mind to dwell on such matters.
