produce a line from M equal to that angle, continued till it cut
a line perpendicular to v, as at V; then is V the vanifliing point
for the fide of the roof of both houfes, and a line from V to V
will be the vanifliing line of the plane which the roof is in, and
H will be the vanifliing point of fhadows lying in the faid
plane; and producing V V at pleafure, and meeting it in 0 at
Fig. 44, by a parallel from S, 0 will be the vanifhing point of
the fun’s rays on that plane. Extend the compaffes from V to
and place it below the horizon, and that point will ferve for
the other fide of both roofs. The houfes being completed in
their outlines, according to thefe vanifliing points, proceed to
fliade them upon a fuppofition that the light comes on in the
front of the picture, and in a direction from the left hand pa-
rallel to the dotted line d b. Therefore the point b will be the
vanifliing point of the fhadows falling upon the ground plane,
and producing b perpendicular to the vanifhing line VV, H
will be the vanifhing point as aforefaid. The place of the fun
S is fixed very low, not as a precedent, but that it might throw
the fliadow of the firft houfe on the fecond, affording an occa-
