(From 'The Wrecker' by Robert Louis Stevenson and Lloyd Osbourne, Chapter XII, published 1892)
. . . And with that he smiled like a man recalling something. “Look here, that brings a yarn in my head,” he resumed; “and for the sake of the joke, I'll give myself away. It was in 1874, I shipped mate in the British ship Maria, from 'Frisco for Melbourne. She was the queerest craft in some ways that ever I was aboard of. The food was a caution; there was nothing fit to put your lips to—but the lime-juice, which was from the end bin no doubt; it used to make me sick to see the men's dinners, and sorry to see my own. The old man was good enough, I guess; Green was his name—a mild, fatherly old galoot. But the hands were the lowest gang I ever handled; and whenever I tried to knock a little spirit into them, the old man took their part! It was Gilbert and Sullivan on the high seas; but you bet I wouldn't let any man dictate to me. 'You give me your orders, Captain Green,' I said, 'and you'll find I'll carry them out; that's all you've got to say. You'll find I do my duty,' I said; 'how I do it is my lookout; and there's no man born that's going to give me lessons.' Well, there was plenty dirt on board that Maria first and last. Of course, the old man put my back up, and, of course, he put up the crew's; and I had to regular fight my way through every watch. The men got to hate me, so's I would hear them grit their teeth when I came up. At last, one day, I saw a big hulking beast of a Dutchman booting the ship's boy. I made one shoot of it off the house and laid that Dutchman out. Up he came, and I laid him out again. 'Now,' I said, 'if there's a kick left in you, just mention it, and I'll stamp your ribs in like a packing-case.' He thought better of it, and never let on; lay there as mild as a deacon at a funeral; and they took him below to reflect on his native Dutchland.
What does I made one shoot of it off the house mean in this context; especially, the words of it trouble me - what do they mean there?
