ut fixing the

_Flatness_ of tint is a matter of great consequence, and of equal
difficulty; and is considered a great excellence, as the clearness and
beauty of the gradations mainly depend on it. All mechanical means to
produce it will betray themselves;--regulated by any such principle, a
blue sky would become a tea-tray! Nature distinctly rejects all that is
mechanical: skill alone will enable the student to overcome this
difficulty, in addition to observing its process by a professor.

Meditate well the mixture before applying it; then dash it on with the
greatest decision,--always at once, and not backwards and forwards, and
the greatest clearness will be the result.

The greater the diversity of colour, from the transparency of most
colours in water, so much more will be its resemblance to nature.

Wiping out the lights, such as the foliage of trees, or any other forms
required, is performed by first wetting the part or form to be taken
out, with the brush--applied as it would be in painting--and, after the
gloss on the water has subsided, with a clean piece of cotton rag or the
pocket handkerchief, folded on the fore finger, the colour intended to
be removed must be whisked out with some smart degree of force: and in
the event of the light not coming out clean and sharp enough (from
perhaps being too dry), the application of the India-rubber to the part
will effect it. The colours intended are then laid over the parts so
wiped out.

OF TINTS.

MAKING good Tints has ever been a matter of extreme difficulty, great
perseverance, and too often entire loss of time; and, in the event of
success occasionally attending the student's exertions, it is a thousand
to one he never gets them twice alike; for that which is done by
_accident_ cannot be repeated. The very difficulty attending them, from
want of knowledge of those colours that blend well and harmonize in
their natures, and the many requisite to charge the memory with, renders
them so easily forgotten, that few but professors ever achieve the
object sought.

To obviate this,--to save the student's time, that he may devote the
more to the attainment of his pursuit,--that he may be enabled to tint a
drawing in half an hour, when he would have spent three in making a good
tint or two (presuming his capability to do it at all),--induced the
