To Dye Black
Boil two handfuls of logwood with a little sumach and elder bark for an hour; put in the hackles or feathers, and boil very gently. Put in a little bruised copperas, a little argil, and some soda; leave the feathers in for some hours with a gentle heat, then wash the dye well out of them, dry and dress them. The argil and soda must be used sparingly.
