-ect. ii. on perspective. 61
Compofe a connected chain of precepts, in which a
ftudent may proceed gradually,
Thought following thought, and ilcpby ftep kd on-
I fliall juft hint, that it is not always neceflary to
have, on a drawing, every line to every point, at
Once; but, after thofe relating to one object have
been drawn with the pencil, and the requillte parts
inked in, the pencil lines may be difmiffed. In
fome cafes it is fcarcely hecelfary to draw lines at
all, but, by laying the edge of a ruler from point t#
point, fo much of that line may be taken as occafiori
requires.
Nor would I advife my friends to draw by the
regular procefs of perfpe&ive, every minute parti-
cular in a compofition, every ornament of a mould-
ing, or every inequality of furface: the principal
lines and fpaces, if juftly inferted, will regulate
the inferior: and trifling objects are not worth the
time, and the trouble, they wafte. 13e it always
remembered, that the Utility of perfpective is to
deceive the eye of a fpectator; and furely an eye
and a hand accuftomed to infpect, and to operate,
by judicious principles, whofe intelligence arifes
from fyftematic knowledge, will be very adequate
to fuch deception; always fuppofmg, that the ob-
jects in tiueftion have been well underftood, and
A
that practice has imparted a facility in their delinea-
tion ; and indeed, I may juftly affeft, that many
objects are with more eafe and re^dineis delineated
from their originals, by an accurate hand, than by
the rules of perfpective ; of which the capitals of
