the surface should be cleared from all the surplus paste with the
end of the scraper, and then rubbed off with shavings or old rags, and
made quite clean. For birch or oak, some use whiting or soft putty
moistened with linseed-oil for the filling; this preparation prevents in
a great measure the rising of the grain. For white delicate woods, such
as sycamore, maple, or satin-wood, plaster of Paris, mixed with
methylated spirit, is used. When polishing pine, a coat of Young's
patent size (2d. per lb.) is used instead of the above mixtures, and
when dry is rubbed down with fine glass-paper.
Some workmen, who regard their modes of filling-in as important secrets,
do their work surprisingly quick by the methods here given. The various
processes are soon acquired by a little practice, and contribute greatly
to the speedy advancement of a smooth and imporous ground, which is the
most important point to observe in polishing.
=Applying the Polish.=--In commencing to use the polish some are
provided with a small earthenware dish, into which the polish is poured
for wetting the rubbers; while others make a slit in the cork of the
polish bottle, and so let it drip on to the rubber; whichever method is
adopted, the rubber should not be saturated, but receive just enough to
make a smear. Every time after wetting the rubber and putting on the
cover it should be pressed upon the palm of the hand, or if a small
rubber it can be tested between the thumb and finger. This is an
important operation, for by it the polisher can easily tell the exact
state of moisture, and at the same time, by the pressure being applied,
the moisture is equalised. The tip of the finger should then be just
dipped into the linseed-oil, and applied to the face of it; if the
rubber should be rather sappy, the greatest care must be used or a
coarse streaky roughness will be produced; extreme lightness of hand is
required until the rubber is nearly dry. (It would be a serious error to
bear heavily on the rubber while the surface is moist; to do so, and to
use too much oil on the rubber, are the causes of many failures in
polishing.)
In commencing to work, pass the rubber a few times gently and lightly
over the surface in the direction of the grain; then rub across the
grain in a series of circular movements, all one way, in full and free
sweeping strokes, until the rubber is dry. Continue this operation until
the pores are filled in, and the surface assumes
