I grew bolder. My common sense told me I must have fancied it all. I walked over to the mainmast, and looked behind the pinrail that partly surrounded it, and down into the shadow of the pumps; but here again was nothing. Then I went in under the break of the poop. It was darker under there than out on deck. I looked up both sides of the deck, and saw that they were bare of anything such as I looked for. The assurance was comforting. I glanced at the poop ladders, and remembered that nothing could have gone up there, without the Second Mate or the Time-keeper seeing it. Then I leant my back up against the bulkshead, and thought the whole matter over, rapidly, sucking at my pipe, and keeping my glance about the deck. I concluded my think, and said "No!" out loud. Then something occurred to me, and I said "Unless--" and went over to the starboard bulwarks, and looked over and down into the sea; but there was nothing but sea; and so I turned and made my way forrard. My common sense had triumphed, and I was convinced that my imagination had been playing tricks with me. I reached the door on the portside, leading into the fo'cas'le, and was about to enter, when something made me look behind. As I did so, I had a shaker. Away aft, a dim, shadowy form stood in the wake of a swaying belt of moonlight, that swept the deck a bit abaft the main-mast. It was the same figure that I had just been attributing to my fancy. I will admit that I felt more than startled; I was quite a bit frightened. I was convinced now that it was no mere imaginary thing. It was a human figure. And yet, with the flicker of the moonlight and the shadows chasing over it, I was unable to say more than that. Then, as I stood there, irresolute and funky, I got the thought that someone was acting the goat; though for what reason or purpose, I never stopped to consider. I was glad of any suggestion that my common sense assured me was not impossible; and, for the moment, I felt quite relieved. That side to the question had not presented itself to me before. I began to pluck up courage. I accused myself of getting fanciful; otherwise I should have tumbled to it earlier. And then, funnily enough, in spite of all my reasoning, I was still afraid of going aft to discover who that was, standing on the lee side of the maindeck. Yet I felt that if I shirked it, I was only fit to be dumped overboard; and so I went, though not with any great speed, as you can imagine.
