Chap. CCCXXXIV.—The Seasons are to be observed.
In Autumn you will represent the objects according as it is more or less advanced. At the beginning of it the leaves of the oldest branches only begin to fade, more or less, however, according as the plant is situated in a fertile or barren country; and do not imitate those who represent trees of every kind (though at equal distance) with the same quality of green. Endeavour to vary the colour of meadows, stones, trunks of trees, and all other objects, as much as possible, for Nature abounds in variety ad infinitum.
Chap. CCCXXXV.—The Difference of Climates to be observed.
Near the sea-shore, and in southern parts, you will be careful not to represent the Winter season by the appearance of trees and fields, as you would do in places more inland, and in northern countries, except when these are covered with ever-greens, which shoot afresh all the year round.
Chap. CCCXXXVI.—Of Dust.
Dust becomes lighter the higher it rises, and appears darker the less it is raised, when it is seen between the eye and the sun.
