Repeat this process again, and then rub the wood with the following composition; put into a glazed earthern vessel a pint of strong vinegar, two ounces of fine iron filings, and half a pound of pounded galls, and allow them to infuse for three or four hours on hot cinders. At the end of this time augment the fire, and pour into the vessel four ounces of coperas sulphate of iron) and a chopin of water having half an ounce of borax, and as much indigo dissolved in it; and make the whole boil till a froth rises. Rub several layers of this upon the wood; and when it is dry, polish it with leather on which a little tripoli has been put.
