A dog-toothed laugh laughed Reuben Paine, and bared his flenching-knife.
"Yea, skin for skin, and all that he hath a man will give for his life;
But I've six thousand skins below, and Yeddo Port to see,
And there's never a law of God or man runs north of Fifty-Three:
So go in peace to the naked seas with empty holds to fill,
And I'll be good to your seal this catch, as many as I shall kill!"
- Rudyard Kipling, "The Rhyme of the Three Sealers."
