You know how one feels what a sailing vessel is going to do, two or three seconds before she does it, when one has the wheel. Riders say the same of a horse, but that's less strange, because the horse is a live animal with feelings of its own, and only poets and landsmen talk about a ship being alive, and all that. But I have always felt somehow that besides being a steaming machine or a sailing machine for carrying weights, a vessel at sea is a sensitive instrument, and a means of communication between nature and man, and most particularly the man at the wheel, if she is steered by hand. She takes her impressions directly from wind and sea, tide and stream, and transmits them to the man's hand, just as the wireless telegraph picks up the interrupted currents aloft and turns them out below in the form of a message. You see what I am driving at; I felt that something started in the cupboard, and I felt it so vividly that I heard it, though there may have been nothing to hear, and the sound inside my head waked me suddenly. But I really heard the other noise. It was as if it were muffled inside a box, as far away as if it came through a long-distance telephone; and yet I knew that it was inside the cupboard near the head of my bed. My hair did not bristle and my blood did not run cold that time. I simply resented being waked up by something that had no business to make a noise, any more than a pencil should rattle in the drawer of my cabin table on board ship. For I did not understand; I just supposed that the cupboard had some communication with the outside air, and that the wind had got in and was moaning through it with a sort of very faint screech. I struck a light and looked at my watch, and it was seventeen minutes past three. Then I turned over and went to sleep on my right ear. That's my good one; I'm pretty deaf with the other, for I struck the water with it when I was a lad in diving from the foretopsail yard. Silly thing to do, it was, but the result is very convenient when I want to go to sleep when there's a noise. That was the first night, and the same thing happened again and several times afterward, but not regularly, though it was always at the same time, to a second; perhaps I was sometimes sleeping on my good ear, and sometimes not. I overhauled the cupboard and there was no way by which the wind could get in, or anything else, for the door makes a good fit, having been meant to keep out moths, I suppose; Mrs. Pratt must have kept her winter things in it, for it still smells of camphor and turpentine.
