PERSPECTIVE.

or a slip of paper may be pasted to the drawing, which
will give sufficient length for the purpose required.

Parallel Perspective is when the object to be repre-
sented has one of its sides parallel to the plane of the
picture, and which side, as all the lines run parallel,
cannot have any vanishing lines. In parallel perspective
the centre of the picture is the vanishing point of those
lines which are at right angles with the lines of the side

o o

parallel to the picture.

Oblique Perspective is so called when the sides of the
object stands in an oblique direction to the plane of the
picture, in which case the lines of both sides will be
vanishing lines.

LESSON IT.

To draw a row of Trees placed at equal distances, in

Perspective.

Let A BCD be the plane of the picture, and EF the
horizontal line. Continue the horizontal line to anv dis-
tancef, and mark off the length of the picture upon it,

which will give the point of distance H ; next draw the
line GI, on which the trees are to be placed, and then
