filver with the quickfilver, which will add to the beauty of the
work.

This is commonly praclifed upon black and coloured Wood,
polifJbing them with a tooth.

If you would have the compofition more beautiful, grind tin
glafs and wafh it till it leaves the water clear ; then mix it in a
ihell with fome gum, and fill up the engravings with it, with a
pencil; then let it lie for three or four houts to dry, and quicken
it with the compofition of mercury and leaf filver.

To Jia'in Wood red. Take half a pound of fernambouc, or
what other you think fit; rain water, a handful of quick lime,
and two handfuls of afhes ; let them fteep for half an hour in the
water, and fettle to the bottom ; then take a new earthen pot,
and put in the fernambouc, with the ley made of lime and afhes;
and, having fteeped half an hour, boil it. Then let it cool a lit-
tle, and pour it into another new pot, adding to it half an ounce
of gum arabic; then put fome rain water and a piece of alum
into another pot or pan ; boil it, foak the Wood in this alumed
water, then take it out and dry it ; then warm your red colour,
and with a brum rub it as long as you think necefTary; then
dry it and polifh it with a dog's tooth, and it will be of a mining
fcarlet colour.

To ftain Wood of a yellow colour. This may be done either
with French berries and alum, or with turmeric or faffron, or
merita earth.

A polijhed black for Wood. Cover the Wood with lamp
"black, ground with gum water, with a pencil j and when it is
dry polifh it with a tooth, and it will look very well.

Another black dye for Wood. Put little pieces of very rufty
iron into good black ink, and let it Hand for fome days; after-
wards rub the wood with it, and it will penetrate it; then po-
lifh it with a tooth, and it will look very beautiful.

To counterfeit ebony Wood. The moft iblid Wood, and freeft
from veins, isbeft; fuch as pear-tree, apple-tree, and fervice-
tree ; take any of thefe Woods, and black it well, and when it
is dry rub it with a cloth ; then, having made a little brufh with
rufhes, tied near the ends, melt fome wax in a pot, mixing fome
lamp black with it; then with the brufh throw on fome of the
wax, brufhing it till it mine like ebony ; then rub it with a cloth,
and fome of the wax.

The Wood mould be well polifhed and rubbed, before it is
blacked.

Holley is the beft of Woods for counterfeiting of ebony. This
is to be put into a hat-maker's copper, where he dyes his hats;
and when it has been tinged to the thicknefs of a fix-pence, which
you may know by cutting it, take it Qut and dry it in the fhade,
