10 GENERAL CONSIDERATIONS 



4. Cost of Administration. The marking of the trees to be 

 cut or left, extra inspection and supervision, to see that cutting 

 and other work is carefully and properly executed, are likely 

 to be necessary. 



5. Costs Due to Making the Investment a Permanent One. 

 The investment in the value of the land may become per- 

 manent instead of being terminated, through sale or devotion 

 to other use, when the area is cut over. 



A considerable investment in wood capital (the growing 

 stock) is required where silviculture is systematically applied. 

 Interest and taxes upon the investment in land and wood 

 capital must be met.
