 differ considerably according to circumstances, but whatever 

 they may be, they can be brought under one of the following 

 two headings : 



1. The realisation of indirect effects, such as landscape 



beauty, preservation or amelioration of the climate, 

 regulation of moisture, prevention of erosion, land- 

 slips, avalanches, etc. 



2. The management of the forest on economic principles, 



such as the production of a definite class of produce, or 

 the greatest possible quantity of produce, or the best 

 financial results. 



It rests with the owner of the forest, in so far as his 

 choice is not limited by the laws of the country, to determine 

 in each case what the objects of management shall be, and it 

 then becomes the duty of the forester to see that these objects 

 are realised to the fullest extent.

 special and distinct management, but in the majority of cases 

 they can be produced in combination with economic working.

 a special class, or the greatest quantity of produce, or the best
