Peel and remove all the green and pink portions from the rind of a large watermelon. Cut the rind into cubes or slices and measure 4 quarts. Drop the rind into a kettle of boiling water, boil for 5 minutes, and drain. Cool. Dissolve 4 T Slaked lime (obtainable at your drugstore) in 2 quarts cold water Pour the solution over the watermelon rind and let rind stand for 3 hours. Drain and rinse thoroughly. Cover the rind with clear cold water, bring to a boil and boil until the rind is tender. Combine 2 cups sugar, 1 cup vinegar, and 4 cups water. Add 2 T each of whole allspice and whole cloves, 4 sticks cinnamon and 2 pieces of ginger root, all tied in a bag. Bring to a boil and boil for 5 minutes. Add the rind and 2 hot peppers, bring again to a boil, and simmer for 30 minutes. Let the rind stand in the syrup in a cool place for 12 to 24 hours. Add 3 Cups vinegar and 2-4 cups sugar according to taste, bring to a boil and simmer until the rind is transparent. If the syrup becomes too thick before the rind is clear, add 1/2 cup hot water from time to time as needed. Discard the spice bag, pack the rind and the boiling-hot syrup into hot jars and seal.
