For tanning with the hair on, the skin should first be cleaned, every particle of loose fat or flesh, being removed, and the useless parts cut away. When this is done, it should be soaked for an hour or two in warm water. The following mixture should then be prepared Take equal parts of:
3.Sulphate of soda
Mix with enough water to sufficiently produce the consistency of thin batter.
This preparation should be painted thickly on the flesh side of the skin, after which these sides should be doubled together and the pelt left in an airy place. Let this set for 24 hours.
A second mixture should next be prepared. This should consist of:
4. 2 parts Sodium carbonate
1. 3 parts borax
5. 4 parts Castile or other hard soap:
Melt all together over a low heat source.
At the end of twenty-four hours, after the application of the first mixture, the second should be applied in a similar manner, and the fur again folded and left for 24 hours.
Next, make a mixture of equal parts of:
1 part Salt
6. 1 part Alum
Dissolve in warm water and thicken with coarse flour to the consistency of thin paste. Spread this thickly over the skin and allow it to dry. Stretch the skin too prevent shrinkage and scrape off the flour mixture with the bowl side of a spoon. A single application of the last-named dressing is generally sufficient for small skins; but a second or third treatment may be resorted to if required, to make the skin soft and pliable, after which it should be finished off with sand-paper and pumice stone. A skin can be dressed as soft as velvet, and the alum and salt will set the hair securely.
