Prepare feathers by washing and rinsing thoroughly in hot water. Be careful about rinsing to remove every particle of soap that may adhere to the fibre, after which prepare bath as follows: One teaspoonful of indigotine powder, diluted in one gallon of boiling water, and add thereto about half a teaspoonful of oxalic acid, stirring around well to thoroughly dissolve every particle of color. Enter feathers and let them remain in bath about four minutes; after which take out and rinse in luke warm water to remove the acid in feathers; next prepare a bath of one gallon of hand warm water and add a small handful of starch; add thereto a cupful of boiled logwood liquor and a few grains of copperas, enter feathers, let remain in bath about three minutes; take out and dry by rubbing between the hands in powdered starch, and beat out on a clean board until all the starch has been removed. Should you find your color darker than shade required, prepare a bath of half a teaspoonful of oxalic acid in a gallon of hand warm water, and pass feathers through about half a minute; take out and pass through boiling water, after which pass through starch bath and dry. Should you find shade too light, add more logwood to bath, increase temperature, let remain in a couple of minutes longer and dry.
