During the first part of this day (Wednesday) the wind was light, but after noon it came on fresh, and we furled the royals. We still kept the studding-sails out, and the captain said he should go round with them if he could. Just before eight o'clock (then about sundown, in that latitude) the cry of ``All hands ahoy!'' was sounded down the fore scuttle and the after hatchway, and, hurrying upon deck, we found a large black cloud rolling on toward us from the southwest, and darkening the whole heavens. ``Here comes Cape Horn!'' said the chief mate; and we had hardly time to haul down and clew up before it was upon us. In a few minutes a heavier sea was raised than I had ever seen, and as it was directly ahead, the little brig, which was no better than a bathing-machine, plunged into it, and all the forward part of her was under water; the sea pouring in through the bow-ports and hawse-holes and over the knight-heads, threatening to wash everything overboard. In the lee scuppers it was up to a man's waist. We sprang aloft and double-reefed the topsails, and furled the other sails, and made all snug. But this would not do; the brig was laboring and straining against the head sea, and the gale was growing worse and worse. At the same time sleet and hail were driving with all fury against us. We clewed down, and hauled out the reef-tackles again, and close-reefed the fore-topsail, and furled the main, and hove her to, on the starboard tack. Here was an end to our fine prospects. We made up our minds to head winds and cold weather; sent down the royal yards, and unrove the gear; but all the rest of the top hamper remained aloft, even to the sky-sail masts and studding-sail booms. Throughout the night it stormed violently,-- rain, hail, snow, and sleet beating upon the vessel,-- the wind continuing ahead, and the sea running high. At daybreak (about three A.M.) the deck was covered with snow. The captain sent up the steward with a glass of grog to each of the watch; and all the time that we were off the Cape, grog was given to the morning watch, and to all hands whenever we reefed topsails. The clouds cleared away at sunrise, and, the wind becoming more fair, we again made sail and stood nearly up to our course.
