Pare 6 oranges very thinly and put the rinds into a gallon jar. Add the juice of the fruit. Add 1 pint cold water, close the jar, and let the liquid stand for three days, stirring it now and then. Strain into an enamel dish, add 2 to 3 pounds sugar, and bring to a boil. Add a full pint of orange juice and strain it again. Finally, add about 2 quarts rum and bottle.
