To make strong white wax, take three parts of white rosin and one of
mutton suet; let them simmer ten minutes or so over a slow fire,
dropping in a small quantity of essence of lemon, pour the whole into a
basin of clear cold water, work the wax through the fingers, rolling it
up, and then drawing out until it is tough. It cannot be worked too
much. By using this wax the pristine colours of the silk you use in fly
making are preserved; common shoemakers wax soils the silk too much.
