GENDARME BLUE.
This color requires a pure bottom, that is, naturally white or bleached. After cleaning, respectively washing in warm soap, which must not even be omitted with bleached feathers, and thorough rinsing, prepare a bath and dye as for dyeing light blue with indigo carmine. Then add some aniline green and navy blue to the bath, re-enter the feathers which have been taken up before making the addition, work them well while raising the temperature to the boiling point; continue at this temperature for one-half hour longer, lift, rinse, starch and dry as usual.
