The captain of the steamer stopped by where I was watching the flying fish fizz out of the blue-ink-like water, skim along for some distance, and drop in again, often, I believe, to be snapped up by some bigger fish; and he gave me a poke in the shoulder with one finger, so hard, that it hurt. "Yes?" I said, for he stood looking hard in my face, while I looked back harder in his, for it seemed such a peculiar way of addressing one, and his manner was more curious still.
