Take a nice piece of the fillet or leg of fresh pork; rub it with a little salt, and score the skin. Put it into a pot with sufficient water to cover it, and stew it gently for two hours or more, in proportion to its size. Then put into the same pot a dozen or more sweet potatoes, scraped, split, and cut in pieces. Let the whole stew gently together for an hour and a half, or till all is thoroughly done, skimming it frequently. Serve up all together in a large dish.
