ction; the more precisely and intimately
one attempts to render detail, the smaller the scale of the technique
requires to be, and the greater the difficulty. Consequently, the more
the reduction which the drawing is likely to undergo in printing,
the more one will be obliged to disregard the finer details. These
finer details need not, however, be absolutely ignored. Notice, for
instance, the clever suggestion of the sculpture in the admirable
drawing by Mr. F. E. Wallis, Fig. 45. The conventional drawing
of the facade, Fig. 46, is a fine illustration of the decorative
effect of color obtainable by emphasizing the organic lines of
the design.

[Side note: _Foliage and Figures_]

The elements in a perspective drawing which present most difficulties
to the architectural draughtsman are foliage and figures. These
are, however, most important accessories, and must be cleverly
handled. It is difficult to say which is the harder to draw, a tree
or a human figure; and if the student has not sketched much from
Nature either will prove a stumbling-block. Presuming, therefore,
that he has already filled a few sketch-books, he had better resort
to these, or to his photograph album, when he needs figures for
his perspective. Designing figures and trees out of one's inner
consciousness is slow work and not very profitable; and if the
figure draughtsman may employ models, the architect may be permitted
to use photographs.

Unhappily for the beginner, no two illustrators consent to render
foliage, or anything else for that matter, in quite the same way,
and so I cannot present any authoritative formula for doing so.
This subject has been treated, however, in a previous chapter, and
nothing need be added here except to call attention to an employment
of foliage peculiar to architectural drawings. This is the broad
suggestive rendering of dark leafage at the sides of a building,
to give it relief. The example shown in Fig. 47 is from one of
Mr. Gregg's drawings.

The rendering of the human figure need not be dealt with under
this head, as figures in an architectural subject are of necessity
relatively small, and therefore have to be rendered very broadly.
Careful drawing is none the less essential, however, if their presence
is to be justified; and badly drawn figures furnish a tempting
target for the cri
