CHAPTER II. 
THE FOREST. 
Forest is a Term variously applied in this country. As here 
used it applies to all collections of trees except such as are 
grown for fruit. It may, then, apply to a picce of land on which 
seedlings have only recently been planted, or to what is termed 
brush land, or to land heavily stocked with trees. 
TREE GROWTH AFFECTED BY LIGHT CONDITIONS. 
So Important is Sunlight to the Growth of Trees that it 
is sometimes said to be the purpose of trees to convert sunlight 
into wood. Practically all trees make their most rapid growth 
in full sunlight There is, however, quite a difference in the 
power of various trees to get along with small amounts of direct 
sunlight. It is the object of good forestry to grow as much 
good timber as possible upon the land, just as good agriculture 
consists in growing the largest amount of farm crops upon the 
land. An acre of land covered with trees of the same species, 
it is estimated, will lay on the same amount of woody fibre 
whether the stems are large or small, the amount of wood 
formed each year being in direct ratio to the amount of foliage 
covering the land that is in good active condition. 
It is known that some trees will do very well in the shade 
of other trees. This gives a chance to grow trees in a sort of 
two-storied fashion, having the land nearly covered with the 
foliage of one set of trees which require the full exposure to 
sunlight, and underneath the land covered with the foliage of 
trees which will endure the shade of those above them, just as 
pumpkins can be grown under corn. On account of this 
peculiarity of trees, foresters have divided them into two 
classes, one of which is called light demanding and the
