greater exactnefs, obferve, that your ftrokes be neither too clofe
nor too wide.
For your more exact obfervation, you fhould prac~Ufe by fuch
prints as are more loofely fhadowed, left, by imitating the more
dark, you fhould not know where to begin or where to end.
5. After you have engraven one part of your work, if will be
proper to fcrape it with the {harp edge of your burnifber or other
graver, carrying it along even with the plate, to take off the
roughnefs of the ftrokes ; but, in doing this, youmuft take great
care not to make fcratches in it.
6. And, that you may the better difcern that which is engra-
ven, dip your roller, made of felt or caftor, in oil, and rub the
places engraven.
Laftly, whatfoever {hall appear tobeamifs, you muft rub out
with the burnifber, and polifh it again very nicely with your
rubber of caftor and oil; and, when you have done, you may boil
your plate a little while in vinegar, and rub it gently with your
rubber before-mentioned.
The method ^Engraving copies or prints. 1. If you would
have it print the contrary way, rub the backfide of the print with
duft of black lead, and lay it on the waxed plate ; and trace over
all the outlines of the defign or print with a needle, or drawing-
point, and vou will find all thofe lines on the wax.
2. Take a drawing-point, not very {harp, and with the point
thereof fcratch of trace over every particular line or out-ftroke ;
which, when you huvedone, it will not be difficult to mark out
all the fhadows as you engrave, having the proportion before you.
3. For copies of letters go over every letter with black lead,
or write them with ungummed ink, and clap the paper on the
waxed plate as before directed.
4. Or take a dog's tooth and rub the paper all over with it,
not miffing any place ; which done, take the paper off the plate,
and fo will all the letters written with the ungummed ink be left
exactly upon the wax.
5. Then take a ftift, and draw all the letters through the
wax upon the plate, and take a linen rag or pencil brufh, and
cleanfe the work from the loofe wax 5 fp will all the letters be
drawn upon the copper.
Of the imitation of copies or prints for Engraving. i. Having
a piece of bees-wax tied up in a fine holland rag, heat the plate
over the fire, till it may be hot enough to melt the wax; then
rub the plate with the wax tied up in the rag, till you fee it
Covered all over with wax, which let be very thin ; if it be not
even, heat it again by the fire and wipe it over gently with a
feather.
