from b draw a line to r, and from c to 9, which, when filled up,
will complete the fhadow.
Example II. Fig. 46. Plate XXVI.
When the Shadow falls at the fame Tame on upright, oblique, and
horizontal Planes.
This figure having the rnoft neceffary lines for reprefent-
ing the two houfes, as well as for finding the fhadow of one
houfe falling upon the other, may be confidered as an example
both of perfpedtive and of fhadow. And as the lines for both
are here joined together in one view, it will fliew their relation,
and the neceffary dependence they have on each other ; which,
it is prefumed, will contribute more to the learner’s advantage,
than if many examples of fhadowing had been added without
regard to the perfpedtive lines.
The horizon and ground line being drawn, fix the center
of the picture as ufual; from which raife a perpendicular as to
d. Make d the diftance of the pidture, and, according to the
obliquity fuitable for the front of the houfe, draw a line to V,
for one vanishing point; next draw V d, and from d draw a line
to v, at right angles with V d\ becaufe the end and front of the
houfe are originally at right angles to each other. Make c M
equal to v d, and whatever angle the pitch of the roof makes,
