DEODAB (CEDBUS DEODABA), KAIL (PINUS EXCELSA). 125 



51 No rigid adherence to the theoretical principles of the regular Deodar 

 or shelterwood compartment system will be insisted on. In many 

 cases it may be possible to carry out in toto the principle of this Kail 

 system ; in' many others however owing to the existence of groups (P us 

 or large patches of canopied poles and saplings it will be necessary 

 to regenerate by amalgamating the theory of the shelterwood and 

 group systems. Strip fellings against the sun may also be tried 

 on south and south-west aspects where considered of advantage. 

 Grenerally wherever practicable a single seeding felling should be 

 made over the whole area to be regenerated, good groups of advance 

 growth or canopied patches of saplings or young poles being retained 

 to form part of the future crop. Within the limitations, the execu- 

 tion of the necessary regeneration felling will be left to the silvicul- 

 tural knowledge of the marking officer, who will so manipulate the 

 canopy of the mother trees that regeneration is obtained and at 

 the same time an undue growth of weeds prevented. This mani- 

 pulation of the canopy will necessarily vary according to the 

 species dealt with. It would be absurd to lay down any dogmatic 

 system of management in dealing with species so different in their 

 silvicultural requirements as the chir and silver fir. Every species 

 comprised in the Regular and Fir Working Circles will be dealt 

 with according to its own individual requirements. 



' The essence of silviculture is to grow each species of tree 

 in the locality most suitable to it. While making every effort to 

 increase up to the desired maximum the proportion of deodar in 

 the mixed forests in all localities suitable to this species, no endea- 

 vour will be made to grow exclusively deodar in forests now 

 occupied by other trees. The mixed character of the crop will be 

 maintained and, taking nature as a guide, the whole area placed 

 in periodic block no. 1 will be regenerated with that species most 

 suitable to the different factors of the locality found in each com- 

 partment. In places not suitable to the growth of coniferous
