136 PRACTICAL FOREST MANAGEMENT. 



it will suffice if this is obtained into two rotations. Single trees of 

 any size are not wanted among the future crop but groups of good 

 poles not bigger than about 8 inches diameter covering a 

 sufficient large area may be kept to form part of the future crop 

 if this is considered desirable. Irregular patchy pole crops are not 

 required and should be regenerated. Where the advance growth 

 has been rendered worthless by suppression or by the groat frost 

 of 1905, it should be clear felled and allowed to come up again 

 as coppice. 



Marking " Regeneration fellings (periodic blocks I and VI combined) 



(1) If the existing regeneration is good, it should be opened 



out uniformly by removing the overhead cover. 



(2) If the existing regeneration is badly grown, damaged by 



suppression or by the frost of 1905, it should be cut 

 back. The over wood is not cut back wholesale ; 20 

 to 25 well grown trees per acre properly distributed over 

 the area should ba reserved for protection and seed. 



(3) Where regenerationMoes not exist at present, a moderate 



seeding felling will be carried out among tha dominant 

 and dominating trees, removing at the same time sup- 

 pressed sal and other trees of the main crop. 



(4) In the above three conditions a shelter of miscellaneous 



trees, such as sandan, in the middle canopy will be 

 required for some time after regeneration has appeared. 

 Such trees should not therefore be ruthlessly destroyed. 



(5) A^ regeneration becomes established, the felling will 



become heavier until the overwood is entirely removed. 

 Where established large regeneration already exists, 

 removal of the overwood should be drastic and the 

 young crop thinned and cleaned. 



(6) As a rule pure sal is not aimed at ; seed-bearers of sain, 



bakli, haldu, bahera, chu , etc., may be selected, where- 

 ever desirable.
