1. The fame method is to be obferved in Etching a fky, for
that which is neareft to the eye muft be fhadowed darkeft; but
in general as faint and foft as may be, lofing itfelf gradually, as
before directed ; and, by how much the nearer the fky comes to>
the ground, by fo much more locfe and faint muft it be ; and,
when they both meet as it were together, the fky muft be quite
loft.
3. When the work has been hatched as exactly as you poffi-
bly can with the needles in imitation of the drawing or print,
compare them well together, and, if you find any thing omitted,
f'upply it ; if amifs, amend it.
4. In Etching a piece of perfpective, after either a drawing or
a print, be fure you fhadow that which is neareft to the eye the
perfected: and ftrongeft ; and that which is farther from it muft
decline in length, breadth, and height, according to art and pro-
portion, letting the fhadows lofc and grow fainter and fainter
gradually, till they are in a manner loft.
Of. Etching or engraving letters. 1. Screw the copper-plate,
after it has been made fit for Etching, to a hand vice, which hold
over a charcoal fire till it be warm ; then rub a piece of virgin-
wax all over the plate, covering it all over very evenly.
2. T hen with a ftifF duck's wing feather, not ruffled, ftorke
it over the wax, laying it even and fmooth in all parts alike, and
let it cool.
3. Then, the letters or writing being written on paper with
ungummed ink made with vermilion, lay the written fide down-
wards upon the waxed plate, and faften the four corners with a
little foft wax, placing the writing fo exactly, that the lines may
run ftraight.
4. Then rub the backfide of the paper all over with a dog's
tooth, taking care not to mifs any part; then pull the paper off"
the plate, and you will find all the letters written on the paper
left exactly upon the wax.
5. Then draw all the letters through the wax on the plate
with a ftift, and afterwards cleanfe the work from the loofe wax,
that you have raifed by fo drawing it with a linen rag or pencil
brufh, and thus will all the letters be drawn on the copper-plate.
6. Then pour upon the plate good aqua-fortis, and it will be
etched ; but, if you take off all the wax and engrave it, the let-
ters will be much more exact and fine, efpecially if your gravers
be well ground and fharp towards the points, and then whetted
fmooth upon a good oil-ftone, and the graving be well perform-
ed ; for Etching will not perform writing fo neatly as engraving.
The method of ufing aqua-fortis. 1. If there are any ftrokes
Into which you would have the aqua-fortis to eat, or any places
where the varntfb, has been rubbed off, melt a little of the prepar-
ed
