To Dye Crimson
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.
