heating, but will have to be put into the hot water again, and the end
pinched and squeezed into form to the shape of the nail, and to fit
easily upon the thumb. When this gets hard, it may be trimmed into
perfect form with a penknife. This artificial nail will answer the
purpose admirably if properly made; and even when the natural nail
is good, the gutta-percha will serve to save it from injury. Good
figuring may also be done by using the blank end of the steel
comb with a rag folded over its edge. We have also used a piece of
gutta-percha to take out the lights. This should be square-ended,
about one inch wide, and three or four inches long, and will do
successful work of a certain class, but not of the best. Many grainers
use a piece of thin horn, in shape something like a spatula, about
three or four inches long and three quarters of an inch wide, with
rounded ends, and quite flexible. With this tool the figure is cut
or scooped out--a sort of quick, side-long motion, very difficult to
describe, and requiring a very considerable amount of practice
before it can be worked with any success. There is, however, the same
objection to this tool as may be urged against the gutta-percha for
figuring, namely, that neither of them take the color clean away, but
leave an accumulation of color on the edge of the figure, which is
fatal to good work; and therefore we cannot honestly recommend the
use of any method but the wiping out with the thumb-nail or its
substitute. When the figure is wiped out it will require to be
softened. By softening, we mean the imitation of those half shades
seen upon and about the figures in the real wood. Between and around
the lights or figure in oak, there is always a lighter tint of color;
this is imitated by doubling a piece of rag into a small roll, and
with the side of this the grain is partially wiped away, but not to
the extent of taking off the whole of the grain. A recent but most
admirable system of graining oak, by means of over-combing, is worked
exactly the reverse of any of the foregoing methods; that is to
say, the figure is first wiped out, and the combing or grain is done
afterwards, when the graining color is dry, in this wise: The graining
color is mixed somewhat thinner than for ordinary graining, and is
brushed over the work sparingly, leaving it just sufficiently strong
to show a clear distinction between the ground and the color. The
light or figure is then softened by drawing the end of a flat hog-hair
fitch, or a small thin mottler, across each figure, and slightly
softening with the badger-hair softener. The figure is broken up a
little with fine lines across it in parts, such as may be seen in the
real wood; but previous to wiping out the figure, streaks of light
should be wiped out and softened on one side of the panel or across
the stiles, in imitation of the reflective lights seen in oak. The
color should also be partially wiped off the rails or stiles at their
