other one in shape and size. Trees will adapt themselves to the
light and moisture conditions to which they are exposed. A tree
that has access to plenty of moisture and sunlight grows evenly
from the ground to its top with a bushy, wide-spreading crown.
The same tree, if it grows in the shade, will reach a greater
height but will have a small compact crown. Trees run a race in
their rapidity of growth. The winners get the desirable places
in the sunlight and prosper. The losers develop into stunted
trees that often die, due to lack of light exposure. A better
quality of lumber results from tall straight trees than that
produced by the symmetrical, branching trees. That is why every
forester who sets out trees tries to provide conditions which
will make them grow tall and with the smallest possible covering
of branches on the lower part of the trunks.

Where trees are exposed to strong winds, they develop deep and
strong root systems. They produce large and strong trunks that
can bend and resist violent winds which sway and twist them in
every direction. Such trees are much stronger and sturdier than
those that grow in a sheltered forest. The trees that are blown
down in the forest provide space for the introduction and growth
of new varieties. These activities are constantly changing the
type of tree growth in the forest.

Our original forests which bordered the Atlantic coast line when
America was first settled, were dense and impenetrable. The
colonists feared the forests because they sheltered the hostile
Indians who lurked near the white settlements. In time this fear
of the forest developed into hatred of the forest. As a result,
the colonists cut trees as rapidly as they could. In every way
