THE CUTTING SERIES. 281 



procedure is not desirable, because it involves extra labour 

 and repetitions in the working plan report. It is preferable, 

 whenever practicable, to have one working plan for each 

 executive charge, because the management of the different 

 working sections can be so arranged, that they supplement 

 each other, thus enabling the forester to provide for a proper 

 allotment of work amongst the staff and a proper distribution 

 of the yield. Where the areas managed on different lines are 

 mixed up with each other, the division of a working circle into 

 two or more working sections becomes an absolute necessity. 

 It need hardly be pointed out, that the areas belonging to one 

 working section need not form a consolidated block ; they may 

 be scattered amongst other areas forming another working 

 section. 



5. Tlic Cutting Series. 



A working section in its simplest shape should consist of a 

 series of age gradations equal to the number of years (or 

 periods) in the rotation, so arranged, that cuttings commence 

 in the oldest age gradation and proceed steadily towards the 

 youngest in the direction, which is determined by the circum- 

 stances of each case. It has, however, been pointed out on 

 page 222, that such a simple arrangement is, in the case of 

 high forest, not always admissible, and that every working 

 section in such a forest must be further divided into several 

 parts, which are called " cutting series." Only such a 

 further division gives the necessary order and elasticity to 

 the arrangement of the coupes. 



Each cutting series should comprise a number of gradations, 

 the ages of which differ by a certain number of years (see 

 diagram on page 223) ; it can be regarded as a working 

 section, in which cuttings are made periodically instead of 

 annually; ordinarily, however, a certain number of cutting 

 series together form one complete series of age gradations, or 

 a working section.
