CHAPTER II. 

 THE FOREST. 



Arboriculture is a term that is applied to the growing of 

 trees for any purpose whatsoever, whether singly or in 

 groups. 



Sylviculture is simply a synonym of the term forestry 

 and is applied to the growing of trees in groups or forests. 



Forest is a Term variously applied in this countrj'. As 

 here used, it applies to all collections of trees except such 

 as are grown for fruit. It may, then, apply to a piece of land 

 on which seedlings have only recently been planted, or to 

 what is termed brush plan, or to land heavily stocked with 

 trees. 



TREE-GROAVTH AFFECTED BY LIGHT CONDITIONS. 



So Important is Simlight 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 cov- 

 ered 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.
