PERSPECTIVE.

LESSON VII.

To draw a Road in Perspective.

When it is intended to represent a road going up hill,
as the right hand road in fig. 8, the lines which form the

sides must be drawn so, that if continued, they would
vanish in a point above the horizontal line, recollecting
that the steeper the road the higher will be the vanish-
ing point.

When the road to be represented is perfectly level,
the sides would meet in the horizontal line, as in the
middle road, fig. 8, which passes over the bridge.

When the road goes down hill, the lines which form
the side, would meet, if continued, below the horizontal
line, as in the left hand road.

The figures on a road going down hill ought always
to be made with their heads below the horizon.
