It is obvious, that in proportion to the less or greater
inclination of the supposed plane, the line L L will be
nearer to, or more distant from, the horizontal vanishing
line, JI If. Towards some point or points in this line L L,
the representations of all right lines parallel to the surface
of the ascent must be drawn ; as is seen (Fig. 8) in
the felled trees, the ruts in the mad, the upper and lower
lines of flic wooden palings, &c.
