Wash and rinse your feathers, after which prepare a bath of one gallon of boiling water and about one ounce of turmeric and half an ounce of copperas; enter your feathers and let them remain in bath about two minutes, more or less, after which take out and rinse twice in cold water. Meantime have boiling a bath of half a pound of logwood to a gallon of water, and enter feathers at boiling temperature, letting them remain in about ten seconds or longer. Should a darker shade be desired, take out and rinse in cold water, after which dilute a half teaspoonful of aniline brown in a gallon of boiling water. Reduce temperature a little with cold water. Enter feathers and let them remain in about three minutes; then cool off a small portion of the bath, and add a small handful of starch, pass feathers through and dry.

If a lighter shade is wanted, add a drop of sulphuric acid to the starch bath and pass feathers through. If the sample to match be more on the yellow order, about twice the amount of turmeric in the first bath; and if desired more on the red, use no turmeric, only copperas, in the first bath. If a darker shade is wanted, let them remain a longer time than that specified in the logwood bath. Any light color can be used to make a Bismarck brown; but if very dark colors are used, it is well to draw off some of the color, doing it in the usual way.
