MEDIUM GREEN.
Prepare your feathers same as for bottle green. Prepare bath by diluting about one ounce of turmeric in a gallon of boiling water, and enter feathers, letting them remain in bath about two minutes; after which take out and rinse in cold water twice. Have boiling a medium strong bath of logwood, and pass feathers through for a few seconds, first cooling off temperature of logwood bath a few degrees with cold water; after which rinse off thoroughly, and prepare a bath of a quarter of an ounce of bichromate of potash in a gallon of boiling water, dissolve it thoroughly, and enter feathers; let them remain in this bath about ten seconds, and take them out and rinse thoroughly in cold water. Proceed to dilute one teaspoonful of turmeric and a half teaspoonful of aniline green in a gallon of boiling water, and reduce temperature a few degrees with cold water. Enter your feathers, and let them remain in bath about three minutes; then take them out and cool off a small portion of bath, and add a small handful of starch, and dry in the usual way.
If found to be too dark, add a few drops of diluted oxalic acid to starch bath, and pass your feathers through for a few seconds. If found too light, rinse off the starch in cold water and return to logwood bath for a few seconds, without increasing the temperature any, and rinse off and give a weak bath of bichromate of potash, rinse off and dry.
