the like judgment when before Nature, they will at once,
and without difficulty, hesitation, or failure, select the best
points of view of any subject of an architectural character.
4th. Concurrently with the form, shade and shadow
may be thoroughly learned.
5th. In combining the Models to obtain examples for
the exercise of the instructions which are given in the
" Guide and Companion/' and in the " Lessons on Art,"
many valuable hints may be gained for the exterior forms
and arrangements of buildings adapted to many purposes.
The forms of ground plans may also be learned in relation
to superstructure. The teacher's time, and that of his
pupils may be economized; numbers may be taught not
only as easily, but more effectively, and more rapidly than
individuals; and so completely, as to supersede the neces-
sity for out-of-door instruction, which is generally unattain-
able, if not impracticable.
This may be proved by viewing the inevitable course
of events when a lesson is proposed to be given actually
from Nature. The first difficulty is to find a subject: This
may be near (not a very frequent occurrence), or it may,
by being distant, consume more time than can be spared
to reach it; a day and hour must be appointed, consistent
first with the teacher's convenience and engagements,
secondly with the pupil's other studies, and thirdly with
the hour of the day when the subject is best illuminated,
When all these have been considered, and satisfactory
arrangements made, there are other impediments to en-
counter : the weather may be unpropitious, too hot, cold,
cloudy, or rainy; or it may have been recently wet, render-
