Boil your hackles or hair in a tea-spoonful of alum, and nearly as much pure tartar, for an hour; bruise two table-spoonfuls of cochineal, and boil them in your clean water; take out the hackles from the alum-water, and put them into the cochineal liquor, and boil for two or three hours slowly or less, according to the shade you require; then take out the feathers and wash them well, and you will have the color desired.
