PLUM.
Feathers that are any color excepting dark green or black can be dyed a beautiful shade of plum. Wash and rinse your goods, and prepare your bath as follows: one pound of logwood to a gallon or more of water, and boil fifteen minutes or longer, then add to bath about a quarter pound of extract of archil, and enter your feathers, letting them remain in bath about five minutes, after which take them out and rinse in cold water. Prepare a bath of half an ounce of bichromate of potash in a gallon of boiling water, more or less, and see that it is thoroughly dissolved; pass feathers through about ten seconds; then take them out and rinse twice in clear cold water; then dilute a small handful of starch in a half gallon of luke warm water, and add to it about half an ounce of soda; pass feathers through for about half a minute and dry.
Should color be found too light for sample, rinse off starch in cold water, and repeat bichromate of potash bath; rinse, starch and dry. An old logwood bath that has been used for other colors will answer for plum, and save boiling up a fresh bath.
