in order to form the periodic blocks of compact shape and 

 fairly equal area, it is necessary to include in them crops 

 which must be regenerated out of their turn so to speak. 

 An example of such a proceeding is here given ; but obvious- 

 ly the variations, which circumstances may render necessary 

 ia applying the method, are endless. 



Example of the general working scheme for a forest of 1,786 acres, treated ns 

 high furesthy the method of Buccessive fellings and thinnings under a rotation of 

 150 years divided into five periods of 30 years each.

The compartment C 1 

 has already been re- 

 generated and con- 

 tains only young 

 seedling growth. 



C a, though placed in 

 the fifth block, con- 

 tains mature high 

 forest, which it will 

 be necessary to rege- 

 nerate in the first 

 period, and to exploit 

 a second time in the 

 fifth period.
