DIVISION OF AREA. 



(8) To assist in the prevention of fires, and to enable the 

 forester to stop any which may have broken out. 



(4) For the location of the annual or periodic coupes. 



(5) To facilitate the transport of forest produce. 



(6) To obviate the necessity for repeated surveys of the 



coupes. 



(7) In some cases, to facilitate hunting and shooting. 



The boundaries of compartments are formed by roads and 

 rides, whenever natural lines are not available. 



The shape of compartments depends on the configuration of 

 the ground. In the plains, a rectangular shape (with sides 

 2:1, or 3:2) is most suitable. On hilly ground, such a 

 shape is rarely practicable ; but the actual shape should, as 

 far as possible, approach that of a rectangle. 



The size of compartments cannot be laid down ; it depends 

 on : 



(1) The intensity of management. 



(2) The extent of danger from fire, and 



(3) The size of the working circle. 



3. The Sub-compartment. 



If within the limits of a compartment considerable differences 

 exist in respect of species, sylvicultural system, age of growing 

 stock, quality of locality, etc., it ma}' be divided into two or 

 more sub-compartments ; the latter may be temporary, if the 

 differences will disappear after some time, or permanent. Sub- 

 compartments may be marked by shallow ditches or other 

 cheap boundary marks. 



The forester should not go too far in the formation of sub- 

 compartments, as it is accompanied by additional expenditure. 

 As a rule, sub-compartments should be formed only if the 

 additional income, derived from different treatment, at least 

 covers the additional expense involved there by.
