OF THE DOWN-HILL VIEW.
If a descending plane be visible to the eve of the
spectator, it is clear that it can be represented upon
paper ; and the remotest, that is, the lowest lines of the
descending plane of the view will have, in that repre-
sentation, a higher place on the plane of the picture than
the nearest, that is, the highest ones of the actual view.
This is shown in the following diagram.
Place on the table, at a short distance from you, a
drawing-board, a portfolio, or any other plane, having
FIG 9'
the nearer end supported, so as to be inclined at an angle
under which the plane is yet visible; and let a by-stander
hold a straight ruler, vertically, at a small distance from
