4 Recipe for an elastic and permanent Varnish, 
Fourth Operation.—This first coat of varnish being per- 
fectly dry, the pumice-stone must be again resorted to, in 
order to remove any small inequalities which may remain. 
Fifth Operation. —When the air is dry and warm, ase= 
coud coat of the black varnish must be applied, and also 
polished with the pumice-stone. 
Sixth Operation.—The finishing hand must now be put 
to the article by laying on ,the yargish to be afterwards de- 
scribed, taking care to employ for this purpose a small and ~ 
compact aa in order to spread the varnish uniformly 
and equally. 
When the first coat of varnish is well dried, it must be 
sprinkled with pumice-stone reduced to fine powder, and 
then rubbed all over with a wet sponge, or a piece of 
fine linen rag also wetted, in order to render the varnish 
perfectly smooth; or in place of pumice-stone, with tripoli 
soaked in oil and rubbed with the palm of the hand. As 
to the second and last coat of varnish, it must be polished 
when well dried, by sprinkling it with starch and rubbing it 
with a piece of old linen rag, which will give it a very fine 
lustre. 
In the event of the varnish being tarnished, or losing its 
lustre by long usage, in order to restore it, place the articles - 
of felt or leather in boiling water for a minute, then let 
them dry thoroughly, sprinkle them with starch, and rub 
them with a piece of dry linen, and they will resume their 
former lustre.
