EFFACING.

the handle of a knife, or a paper cutter. The colour will
then lie on that part nearly or quite as well as on the un-
broken surface of the paper.
Small partial lights in the drawing are to be obtained
either by being scratched out of the broad washes with a
sharp instrument, such as a penknife or an eraser, or by
slightly wetting the necessary space with the brush charged
with clean water: in the latter expedient, let the spot,
when nearly dry, be smartly rubbed with a silk handker-
chief drawn tightly over the finger, or with Indian-rubber.
It must be observed that this is not successfully accom-
plished, unless it be done in such a way as not to leave a
woolly appearance on the surface, or on the edges of the
lights thus obtained.
Chinese White is very useful for small and sharp lights
in the foreground. These lights may be laid on in the
desired forms with solid white, which, when perfectly dry,
may be tinted or glazed over with the colour required to
produce the intended effect. It will be found that if the
colour be mixed with the white in- the first instance, the
effect will be less brilliant; both methods are however
useful, and the difference in their effects is of service
in procuring results adaptable to variety of surface and
intention.
EFFACING, AS A MEANS OF MODIFYING TONE.
This method is usually practised when half lights only
are required; being a process whereby too great a strength
and decision of tone are required. It may be effected with
stale bread, Indian-rubber, a silk handkerchief, or a piece
of chamois leather. The leather, when soiled by the
colour, may be repeatedly washed. The surface requiring
to be acted upon is thus treated:—charging the brush
with pure water, carefully wet that part of the under tint or
