298 OOMPOUXD COPSES UNDER CONTERSION. 



growth of the former. But this must be done at the right time, 

 viz., when the stool-shoots are on the point of spreading out later- 

 ally to meet their crowns and before they have reached the sapling 

 stage, that is to say, as a rule, simultaneously with the extraction 

 of the last poles of the original coppice crops. After such an opera- 

 tion, the new shoots that grow up from the stools cut back, being 

 10, 12 or 15 years behind their seed-grown neighbours, quickly, fill 

 up the interstices in the leaf-cauopy left between these latter, and, 

 where they are exposed enough overhead, catch them up in a few 

 years, but this time without any longer being able to harm them 

 before the First Thinning, which finally removes them, falls due. 



In high forests already constituted as such, all the Regenera- 

 tion Fellings are established volumetrically ; this cannot, of course, 

 be done in copses under concersion. In the latter case the Primary 

 Fellings are naturally not required to furnish anything better than 

 produce insignificant both as regards quantity and quality. It is, 

 therefore, better to establish them by area, and to subject them to 

 the condition that they shall pass through all the crops to be re- 

 generated in a certain limited time, say, the first 12 or 15 years of 

 the current Period. Hence it is only the Secondary Fellings that 

 can be based on volume, and their yield is accordingly determined 

 by dividing the total contents of the trees to fall in the crops under- 

 going regeneration by the number of years to run from the com- 

 mencement of these fellings to the end of that Period. It is, of 

 course, unnecessary to take into account the small coppice poles, 

 some of which must fall in the Primary Felling; these will, on the 

 whole, be a sort of set-off against the trees left standing in the last 

 Secondary Felling.

The Compound Coppice Fellings. 



The Compound Coppice Fellings to be made, while the Prepa- 

 ratory Cuttings and regeneration operations are in progress in other 

 parts of the Working Circle, ought to be located on the basis of
