Two quarts blackberry juice, one pound loaf sugar, four grated nutmegs, quarter ounce ground cloves, quarter ounce ground allspice, quarter ounce ground cinnamon. Simmer all together for thirty minutes in a stew pan closely covered, to prevent evaporation. Strain through a cloth when cold, and add a pint of the best French brandy. Soothing and efficacious in the summer complaints of children. Dose, one tea-spoonful poured on a little pounded ice, once or several times a day, as the case may require. Whortleberry cordial may be made by the same recipe. Good old whiskey may be used for either in the absence of brandy.
