nd draw the outline as exact as you can on the
papered panel. You then paint the ground-work, stump of a tree, the
bill and legs, their proper colour, with water-colours, leaving the
body to be covered with its own natural feathers. In the space you
have left for the body, you lay on very thick gum-water, letting each
coat dry before you lay on another, and so continuing until the gum is
as thick as a shilling. Then take the feathers off the bird; and, as
you proceed, draw a camels'-hair pencil, dipped in gum-water, over the
coat of gum that you have laid on the paper, that it may more readily
adhere. As you strip the bird, you must fix the feathers in their
proper places on the board, and you shave the shafts or stems of the
larger feathers, that they may lie flat. The most ready way to perform
the operation, is to provide yourself with a pair of steel pliars to
take up and lay on the feathers with. You should prepare some small
leaden weights to lay on the feathers, that they may more readily
adhere to, and lie flat on, the gum. The part where the eye is must be
supplied by a small piece of paper, coloured and shaped like one; or
you may, probably, be able to get a glass bead that will answer the
purpose better. In order that the feathers may lie smooth and regular,
when the whole is perfectly dry, lay a book, or a flat board, with a
weight on it.

_The Art of Bronzing._

Bronzing is that process by which figures of plaster-of-paris, wood,
&c. are made to have the appearance of copper or brass. The method is
as follows:

Dissolve copper filings in aqua fortis. When the copper has
impregnated the acid, pour off the solution, and put into it some
pieces of iron, or iron filings. The effect of this will be to sink
the powder to the bottom of the acid. Pour off the liquor, and wash
the powder in successive quantities of fresh water. When the powder is
dry, it is to be rubbed on the figure with a soft cloth, or piece of
leather; but observe, that previously to the application of the bronze
powder, a dark blackish sort of green is first to be laid on the
figure: and if you wish the powder to adhere stronger, mix it with
gum-water, lay it on like paint, with a camels'-hair brush, or
previously trace the parts to be bronzed with gold size, and when
nearly dry, rub the powder over it.
