THE MAJOR CONVOLVULUS.
THIS Plate represents a group of the Major Convolvulus. It
must be observed, that in this plant the pink and purple flowers
grow upon the same stemn; and being one of the tribe of Creepers,
it has a number of tendrils by which it will run up a pole eight
or ten feet high. These tendrils and flowers throw out in a very
free easy manner. This group is drawn in such a manner as to
follow nature as near as possible, and give the learner at the
same time an idea of good taste in grouping.
     In copying from these flowers, I should recommend the learner
not only to draw from them but to study them, that is, to look at
the manner of grouping, and observe how each particular flower
or leaf turns, the different tints or colour of the different flowers,
how one is relieved by another, and in what manner the leaves are
relieved by the different tints given to them ; for example, how the
blue green tint of the back of the leaves, gives effect and force to
the front leaves, by making them appear more forward. Those
tinted brown are leaves that are decaying, and are introduced to
give the whole a more picturesque appearance; it is by having a
correct idea of all these distinct features that the judgment is to
be formed, and both judgment and taste are required in order to
excel in Flower Painting.
     After an attentive examination the whole should be sketched
in with a black lead pencil; then holding the sketch and pattern
at a little distance, observe whether you have got all the
principal stems correct, with  equal freedom  in each ; theni
observe how the leaves lay against or over each other, and
whether they are in their proper places, also the flowers and
buds: if they are so, rub out your black lead sketches, till
they appear so pale that you can correct your drawing ; and
