The cast shadow of trees (452. 453).
4
52.
The image of the shadow of any object of uniform breadth can never
be [exactly] the same as that of the body which casts it.

Light and shade on groups of trees (453-457).

53.
All trees seen against the sun are dark towards the middle and this
shadow will be of the shape of the tree when apart from others.
The shadows cast by trees on which the sun shines are as dark as
those of the middle of the tree.
The shadow cast by a tree is never less than the mass of the tree
but becomes taller in proportion as the spot on which it falls,
slopes towards the centre of the world.
The shadow will be densest in the middle of the tree when the tree
has the fewest branches.
