itself uuder an almost complete canopy. We may therefore 

 qualify the general statement made above by saying that where 

 protection against drought is necessary, the number of seed-bearers 

 per acre may have to be increased very considerably ; it may also 

 be stated that on southern slopes as a rule a larger number of seed- 

 bearers are required than on northerly aspects. 



" In Jaunsar 53 chir regeneration is exceptionally easy to 

 obtain, provided the area can be protected for 15 or 20 years from 

 fire. In favourable localities fire protection alone will bring up 

 young chir like a weed under almost any degree of cover and light 

 grazing probably assists rather than hinders the process. Any- 

 thing in the nature of heavy grazing is harmful. 



" Although regeneration will spring up under almost any cover 

 in favourable localities, i.e., on north aspects or in sheltered bays, 

 a really heavy opening of the canopy gives the best results. As 

 a hint the seeding felling should leave the mother trees 4 to 7 

 crowns width apart. About six good seed-bearers to the acre are 

 suilicient, but as some of the mother trees are sure to die it is 

 better to start with about seven to the acre. A secondary felling 

 may be made if necessary, but this will not always be required. 

 So soon as the young growth is three to five feet high the whole 

 of the overwood should be removed, and if a fire occurs, then the 

 area must bo artificially regenerated. 



" On unf a vo arable areas, (usually hot dry slopes with shallow 

 soil, the above simple procedure cannot be adopted. Fire protec- 

 tion on such areas has often failed to produce adequate regenera- 

 tion, and yet there is plenty of light. Young chir are susceptible 

 to drought, and it is probable that in such places drought and 

 excessive transpiration largely account for the lack of young seed- 

 lings. On such areas even light grazing is harmful. Here a 

 heavy opening of the canopy probably does more harm than good, 

 and if the canopy were denser perhaps regeneration would appear*
