likelihood of such a felling being made in the near future in India. 

 Moreover, these grades are only experimental and the second is 

 known to be too heavy, as it passes the stage at which the 

 increased increment per tree is counterbalanced by the decreased 

 number of trees. 

 The grades are : 



(1) Light. 



(2) Heavy. 



If the basal area of a wood (excluding classes (3) and (4)) is 

 measured after a D grade ordinary thinning then the light incre- 

 ment felling removes 20 30 per cent, of that basal area and the 

 heavy increment felling removes from 30 50 per cent. 



The term " predominating trees " is not used here. The best 

 of the dominating trees are sometimes designated as " predomina- 

 ting " but the distinction is needless as naturally whenever any 

 dominating trees are felled the worst are taken and the best left.
