When last you and I conversed, we spoke of my career as author of books, and teller of slave-stories. A similitude was formed, in which my works to date were likened to so many balls of grapeshot, which when fired at our Enemy pose a nuisance but can never send any slave-ships to David Jones’s Locker where they ought to be all. You exhorted me to leave off gathering more grapeshot and to turn my efforts to finding a single cannonball.
