Boil your hackles or hair in a quarter of an ounce of alum, and the same quantity of pure tartar, an hour gently; wash them out of this, fill your dye-pot with clean water, or as much as will conveniently boil; put in an ounce of well-powdered dye stuff they call "grain," with one drachm of red arsenic, and one spoonful of burnt wine lees, this gives a lustre; wash and rinse well after boiling a short time, and the colour is good.
