3 52 TEE GENERAL WORKING SCHEME. 



The Last Thinning made in a high forest may also have for object 

 the early and gradual production of seedlings on the ground 

 under the standing crop, such as might happen in a forest of silver 

 fir, a seedling crop of which species makes its appearance very 

 gradually but resists well the action of cover overhead. This Last 

 Thinning, which may indeed be termed a Preparatory Primary 

 Regeneration Felling, differs from all preceding Thinnings in that 

 it clears the soil of bushes, removes overtopped trees, and occasionally 

 raises the cover by a judicious lopping off of low branches. It is 

 therefore expedient to characterize it by a special name. To call 

 it a Preparatory Primary Felling would create an ambiguity, 

 since this designation has been applied to another perfectly distinct 

 operation. The term Final Thinning would perhaps be the best to 

 adopt. 



The following two tables are convenient for collecting together 

 the data and informatioo which it is expedient to adduce in support 

 of the estimated annual yield. The first gives the yield of principal 

 produce, the other, the area to be thinned every year, the compart- 

 ments to be operated upon, and the order in which they should be 

 taken up.
