CONSTITUTION OF WORKING CIRCLES. 87 



(4) The thinning and cleaning of the coppice and the artificial 

 regeneration of blanks as described for the simple coppice 

 system. 



A working circle is an area subjected to one and the same 

 silvicultural system and method of treatment and which is 

 exploited by a distinct series- of operations. It may consist of one 

 or more felling series. Having decided on the silvicultural 

 system or systems to be adopted, it now becomes necessary 

 to allot compartments to working circles in accordance with 

 the way in which it has been decided to treat them. The 

 broad outlines of the working plan having already been laid down, 

 the working plan officer will consider the question of the allotment 

 to working circles at the same time as he describes the compart- 

 ments. In order that a working circle may be properly constituted 

 it should contain crops of well graduated ages. As however under 

 present circumstances the distribution of the age classes is never 



normal, the working plan officer must do the best he can with crops ~

 at his disposal and must make the best possible arrangements to tion of 



obtain greater normality in the future. A working circle compris- working

ing as it does forests under one and the same method of treatment 

 need not be in one piece ; in fact it is seldom so. The compart- 

 ments of the Conversion to Uniform Working Circles of Haldwani 

 and Eamnagar are mixed up with compartments allotted to 

 other working circles ; the compartments of the Eegular Working 

 Circle of Kulu are scattered all over the division. On the other 

 hand the Gola Working Circle of South Kheri division and the 

 Thano Working Circle of Dehra Dun form self-contained 

 blocks of forest. Similarly neither need the periodic blocks be 

 concentrated into one place. The regeneration are both in sal 

 and conifers may be scattered over the whole area of the division 

 as is indeed the case in the Dehra Dun and Jaunsar-Bawar plans. 

 On the other hand in the Conversion and Uniform Working Circles 

 of South Kheri and the Chuka Working Circle of Pilibhit the
