Boil two handfuls of red-wood, or ground Brazil-wood, for an hour, with a handful of log-wood; then take a table-spoonful of oil of vitriol, and put it into half a tea cup of cold water; and when the dye-pot is a little cold, add it to the liquor, stir it, and put it on with the hackles or hair, and boil it gently for two hours; take out your material, and put it into cold water; add to the dye it comes out of a little copperas, and a small quantity of pearlashes, about the size of a nut of copperas, and a quarter that size of the ashes; put in your hackles or material again, and when the proper shade is obtained, rinse and wash well, and finish in urine, which brightens them, and your colour is good.
