round the neck of the golden pheasant, is sormed with bright lake
over the yellow, leaving a little os the ground colour uncovered, as
the bend of the neck approaches the light; the very dark touches on
the ruff, that shew nearly black, are dark sepia. Do not use black
under any circumstances on a bright yellow or lake, as it will be sure
/
to make it appear muddy. The breast is shaded up by stippling, with
a fine brush, a fine tint os lake and burnt sienna over the yellow,
taking care to let the parts that catch the strong light appear in the
latter colour. The wings are a deep crimson, with the exception of
their edges, which are os a bright gold colour. The upper part
os the back has a slight tinge os green; the lower part is yellow.
The tail is shaded with gamboge and burnt sienna, and spotted with
sepia. The legs of this bird are black, and must theresore be coloured
with a dark neutral tint.

It would be impossible to convey by words the method os colouring
every variety os these beautisul birds, but is the colours are washed on
with spirit, and, when dry, the seathering is stippled on with a sine
sable pencil, it will give a highly sinished effect, to be exceeded only
by Nature hersels. The darkest touches may be considerably height-
ened by applying a little gum water; this will be sound to give a sine
essect to the head os the silver pheasant, and indeed to all birds that
have dark changing colours. The tree is tinted with a very light
wash os yellow ochre and prussian blue.
