It was this weather and sailing that brought to my mind a little incident that occurred on board the Pilgrim, while we were in the same latitude. We were going along at a great rate, dead before the wind, with studding-sails out on both sides, alow and aloft, on a dark night, just after midnight, and everything as still as the grave, except the washing of the water by the vessel's side; for, being before the wind, with a smooth sea, the little brig, covered with canvas, was doing great business with very little noise. The other watch was below, and all our watch, except myself and the man at the wheel, were asleep under the lee of the boat. The second mate, who came out before the mast, and was always very thick with me, had been holding a yarn with me, and just gone aft to his place on the quarter-deck, and I had resumed my usual walk to and from the windlass-end, when, suddenly, we heard a loud scream coming from ahead, apparently directly from under the bows. The darkness, and complete stillness of the night, and the solitude of the ocean, gave to the sound a dreadful and almost supernatural effect. I stood perfectly still, and my heart beat quick. The sound woke up the rest of the watch, who stood looking at one another. ``What, in the name of God, is that?'' said the second mate, coming slowly forward. The first thought I had was, that it might be a boat, with the crew of some wrecked vessel, or perhaps the boat of some whale-ship, out over night, and we had run it down in the darkness. Another scream! but less loud than the first. This started us, and we ran forward, and looked over the bows, and over the sides, to leeward, but nothing was to be seen or heard. What was to be done? Heave the ship aback, and call the captain? Just at this moment, in crossing the forecastle, one of the men saw a light below, and, looking down the scuttle, saw the watch all out of their berths, and afoul of one poor fellow, dragging him out of his berth, and shaking him, to wake him out of a nightmare. They had been waked out of their sleep, and as much alarmed at the scream as we were, and were hesitating whether to come on deck, when the second sound, proceeding directly from one of the berths, revealed the cause of the alarm. The fellow got a good shaking for the trouble he had given. We made a joke of the matter; and we could well laugh, for our minds were not a little relieved by its ridiculous termination.
