112 PRACTICAL FOREST MANAGEMENT. 



undertaken. This felling will begin from the starting point of 

 Block III. 



" (c) The fuel coupes. All trees which, in the opinion of the 

 Divisional Forest Officer, will never be fit for anything but fuel 

 may be felled annually over areas not exceeding one-twentieth of 

 -the whole felling series less the area of the nal and kokat coupes 

 combined. These fellings will begin from the starting points of 

 Blocks II and IV. 



' The areas prescribed for all clearfelling coupes are maxima 

 and will be limited in practice by the demand and cultivation 

 available. The kokat coupe will be felled only if the demand for 

 kokat exceeds the supply from the sal coupe, and similarly fuel 

 coupes will only be required if the demand for fuel cannot be met 

 from the sal and kokat coupes. 



" Selection fellings. These are prescribed on a 15-year felling 

 cycle over Blocks II, III and IV beginning with Block II, which 

 will, therefore, be worked over in the next five years. At the end 

 of that period the question of selection fellings will have to be 

 re-considered as the working will depend on the extent to which 

 kokat clearfellings have been carried out. All kokat over the 

 exploitable girth will be removed together with sal over 2 feet in 

 diameter unless it is likely to improve in 20 years. At the same 

 time the removal of sal of inferior growth interfering with better 

 stems will be carried out. 



"Thinnings and removal cf dead sal. These two operations are 

 to be carried out at the 'same time and will be made over one 

 periodic block in each felling series annually. The interval between 

 these operations in any given area is therefore four years. 



" Thinnings in the new crop are referred to in Appendix III (3) 

 the thinnings referred to here are confined entirely to congested 

 patches of immature sal. This operation is both important and 

 profitable. From the work already done in this direction it is 

 seen that even after a heavy thinning the remaining sal poles 

 close up so rapidly that after two years it is almost impossible
