that it may the better imbibe the dye water; then polifh it with
an iron, to take off the fouinefs of the dye ; and afterwards, with,
rufh, powder of charcoal, and fallet oil; as is done to ebony.

The Wood of Tunis polifhes eaiily ; well
with a tooth, and is better to cut than ebony, which is very brit-

An excellent blue colour for Wood. Boil a quarter of a pound
of turnfole for an hour, in three pints ofiime water, and colour
the Wood with it.

A violet colour for Wood . Temper Dutch turnfole with water,
and ftrain it through a cloth ; before it is ufed on your work, try-
it on a piece of white Wood, to fee if it be not too deep. When
you have laid on the colour, put fome of the fame colour to a
quantity of water, to render it very thin ; and wafh the Wood
with this, till it become bright; then dry it, burnijfh, and varnifh
it; and, if the Wood be white before, it will then be of an ex-
cellent blue.

Another violet. Boil four ounces of brafil and eight ounces of
logwood together, in two quarts of water, with an ounce of com-
mon alum ; and in thefe boil the W~ood.

A purple colour for Wood. Steep turnfole as is directed for
the violet colour, and add to it the tincture of brafil boiled in
lime water, and it will be an excellent purple ; this ought to be
V2rnifhed, both to beautify, and to preferve it.

A way of /laining, or marbling Wood. Grind white lead and
chalk together on a marble ; put it into a pot, and temper it a-
gain with the yolk of an egg, beaten with water ; then lay on
this white with a large pencil; let it dry, and go over it again
with the fame ; let it dry again, and then take a point made of a
flag's horn ; draw ofT the white, where and in what form you
will; then fprinkle the lime mixed with urine. The violet
Wood which dyers ufe, will become black as ebony ; by fprink-
linc it with lime and urine, plum-tree, and cherry-tree, turn of
a deep red ; the pear-tree and fervice-tree turn reddifb ; wal-
nut-tree grows black, by mingling fome galls in powder with
lime and urine.

A pencil made of mutton fuet, rubbed where you would draw
with yolks of eggs, will do the fame thing.

It will be excellent upon black cherry-tree, plum-tree, or any
Wood of a dark colour.

To make Wood of a fiver colour. Reduce tin glafs in a mor-
tar to fine powder ; add to it water, and grind it to the finenefs
of paint ; put it into an earthen pan, and wafh it two or three
times till it is very clean ; and then mix clear glue with it, and,
having firft warmed the Wood, lay the mixture on it with a
brum s let it dry, and polifh it with a tooth,
