CHAPTER II. 



ORGANISATION OF FORESTS IN WHICH THE 

 SELECTION METHOD IS TO BE MAINTAINED. 



The organisation of forests worked by Selection is as elementa- 

 ij in its character as the corresponding method of treatment itself. 

 iThe first care which it requires, is moderation in the exploitations, 

 this being the only means of systematising them (as far as that 

 can be done in this Method of Treatment), and of ensuring the carry- 

 ing out of all necessary Works of improvement and development. We 

 will now proceed to examine separately the method of organising 

 forests under all the three classes of circumstances which, we have 

 seen above, necessitate Jthe maintenance of the Selection Method ; 

 that is to say, we will show to what it practically reduces itself in 

 forests kept up for protection, what measures it requires in the 

 case of forests situated at high elevations, and in what particular 

 respect it may have to be modified for high forests of altogether 

 limited extent. 



SECTION I. 

 JFoeests of Pkotectiox. 



Forests ittaitttained for the purpose of protection perform their 

 tole more effectivelyj the taller and, hence, the older they are. 

 The expioitability to be adopted here is, therefore, that termed by 

 us Physical, and is determined by the natural death or complete 

 decay of each separate tree. The consequence is that the date of 

 the exploitations, as well as the quota of produce to be extracted 

 «t each exploitation, are always unknown quantities ; and, indeed,
