After great exertions I got it, or the remains of it, into the top, and was making it fast, when the captain, looking up, called out to me, ``Lay aloft there, Dana, and furl that main royal.'' Leaving the studding-sail, I went up to the cross-trees; and here it looked rather squally. The foot of the top-gallant-mast was working between the cross and trussel trees, and the mast lay over at a fearful angle with the topmast below, while everything was working and cracking, strained to the utmost. There's nothing for Jack to do but to obey orders, and I went up upon the yard; and there was a worse mess, if possible, than I had left below. The braces had been let go, and the yard was swinging about like a turnpike gate, and the whole sail, having blown out to leeward, the lee leach was over the yard-arm, and the skysail was all adrift and flying about my head. I looked down, but it was in vain to attempt to make myself heard, for every one was busy below, and the wind roared, and sails were flapping in all directions. Fortunately, it was noon and broad daylight, and the man at the wheel, who had his eyes aloft, soon saw my difficulty, and after numberless signs and gestures got some one to haul the necessary ropes taut. During this interval I took a look below. Everything was in confusion on deck; the little vessel was tearing through the water as if she had lost her wits, the seas flying over her, and the masts leaning over at a wide angle from the vertical. At the other royal-mast-head was Stimson, working away at the sail, which was blowing from him as fast as he could gather it in. The top-gallant sail below me was soon clewed up, which relieved the mast, and in a short time I got my sail furled, and went below; but I lost overboard a new tarpaulin hat, which troubled me more than anything else. We worked for about half an hour with might and main; and in an hour from the time the squall struck us, from having all our flying kites abroad, we came down to double-reefed topsails and the storm-sails.
