Prepare the dyebath as for ponceau (I.), or use an old ponceau bath,
and add to it some aniline cerise (cherry red) and very little extract
of indigo, or solution of fast blue-black. Enter feathers as hot as
possible to handle, work for fifteen to twenty minutes while raising
the temperature to boiling heat; then stop heating, lay down the
feathers, and let them lodge until level; lift, rinse and dry.
II. Prepare a boiling hot, not boiling, bath of anotto, according
to shade, enter the feathers, work them well through, then lay them
down in the bath for twelve hours. Take them up, rinse, pass through
a moderately strong alum bath, rinse again, and dye at 170°F., with
either decoction of red wood (brazil, camwood, etc.,) or fuchsine; lift
and dry.
