in extensive woods ; for instance, there may be a regular 

 demand for timber at two ends of an estate, and two cutting 

 areas will be necessary each year, so as to supply the purchasers 

 without forcing them to go long distances. 



4. Even if the whole forest can be managed on one system 

 and rotation, it may be necessary to have two or more circles, 

 so as to reduce the cutting area in one spot to a workable 

 size. Thus, if 50 acres are to be cut each year, it may be 

 better to cut 25 acres in one place and 25 in another than to 

 have the whole 50 acres cut in one large block. This arrange- 

 ment also facilitates supervision, as the whole work will not be 

 in the charge of one woodman. The workmen also may not 

 have to go so far to their work. 



5. In conifer woods it is desirable to have small felling areas 

 in order to reduce danger from insects. This is ensured by 

 having several working circles. 



Where there are two circles, both worked on a 5o-year 

 rotation, the arrangement of the cutting is somewhat as 

 follows : 



Working Circle B. 



Working Circle A.

 direction. 



In each year both the areas with the same number will be 

 cut. At the end of the rotation each circle will have a com- 

 plete series of age classes. 



Each circle need not form a compact block as in the diagram ; 

 for instance, all the existing conifer woods on an estate, wher- 

 ever they are situated, may be placed together into one circle, 

 and all the broad-leaved woods into another.
