(1) Hub the surface of thin post or tissue-paper with graphite (blacklead), vermilion, red chalk, or other pigment, and carefully remove the excess of colouring matter by rubbing with a clean rag.

(2) Rub into thin white paper a mixture of 6 parts lard and 1 of beeswax, with sufficient fine lampblack to give it a good colour; apply the mixture warm, and not in excess.

(3) Under exactly the same conditions use a compound consisting of 2 oz. tallow, 1/2 oz. powdered blacklead (graphite), 1/4 pint linseed oil, and enough lampblack to produce a creamy consistence.
