Dissolve some indigo in oil of vitriol for twenty-four hours, put a

couple of spoonfuls in your pot, add a little crystal of tartar, put in

your hackles and boil, or at least keep them at a scalding heat, or the

vitriol will burn the feathers, furs, &c., take them out, rinse them

well, and the colour will be lasting.

If to the above liquor some fustic chips, well boiled by themselves, and

the juice added, you may then have any shade of the best green.
