292 COMPOUND COPSES UNDER CONVRSIOX. 



The coppice crops of the Third and Fourth Blocks can be cut 

 as compound copse only once during the entire course of the First 

 Period; but, by reason of the actual distribution of the age-classes, 

 these twQ Blocks will be worked thus in alternate years, so that 

 at the end of the following Period it will be possible to continue 

 the series of Compound Coppice Fellings in the Fourth Block alone. 

 Indeed, the crops in question will be felled only between the ages 

 of 36 and 42 years, so that they will necessarily yield a very large 

 quantity of produce. Moreover, the preceding tables prescribe a 

 thinning of the underwood ia these crops 10 years before they are 

 finally felled. The advanced age fixed for their exploitation and 

 this preliminary Thinning will contribute to modify in the most 

 happy manner the constitution of these crops as re:^ards their 

 component species, while a judicious selection of Standards will 

 endow them with numerous well -grown trees. 



The maintenance of the yield at a sufiiclenfcly high figure du- 

 ring the Second Period may be reasonably counted upon. The re- 

 servation of promising trees in the First Block, the constitution 

 and age of the crops in the Second Block, the abundance of useful 

 material Jin the compound coppice crops composing the Fourth 

 Block, and the reserved fourth of the total volumetric yield, a por- 

 tion of which can always be drawn upon, will be a sure guarantee 

 of this.
