Take a pint measure of bread broken small or crumbed; boil a quart of milk, with a little salt and pour it over the bread; cover and let the bread swell till it can be mashed smooth. Beat 4 eggs and stir into it, with 4 tablespoonsful of flour. Sprinkle a bag inside with flour, pour in the pudding, tie loosely, and boil one hour.
