LESSON IV.

LEAVES.
In the preceding lessons the leaves of the ssowers were very easily
executed, as they had but three shades, all of them in one colour, with few
veins or fibres, but in the succeeding lessons the leaves will essentially
add to the beauty of the subjects, and will require more care both in
drawing and colouring. There is no copy that can be laid before the
student, who desires to execute the foliage of ssowers with spirit and
correctness, that will answer the purpose, in any degree, so well as
the natural leaf. In ssowers there is great difficulty in shewing the
light and shade from nature, and it is therefore requisite that copies
should be studied, in order to render the process familiar to the mind ;
but in single leaves, where there is little or no shadow, the veins and
outline are so distinctly marked, that they are quite as easy to imitate
as any copy that can be placed before the pupil.
This plate contains four different kinds of leaves, drawn from
nature. They are broken from the branch, and laid ssat on a sheet
of white paper.
No. 1. are the leaves of a geranium; it will be necessary to copy
the outlines of these leaves a number of times, on waste paper, before
the drawing that is intended to be coloured is made, so that a freedom
of hand may be obtained, with a spirited and decided touch. The
stalk, as in the former subjects, must be drawn first, and the small
stalks of the Reaves drawn from it. From the end of the stalk the
