PLATE L 



FIG. 1. Represents a tree in a grove or thick plantation 

 of thirty years of age, which has been regu- 

 larly and properly pruned from infancy on- 

 wards. 



FIG. 2. Represents a tree of the same age, on the skirti 

 of a plantation, which has been neglected in 

 the pruning from infancy onwards ; and which 

 now being pruned in a way too frequently 

 practised, is Isft in a state highly injurious to 

 its health, and destructive of the soundness of 

 its timber: For it is manifest, that before 

 the bole can be enlarged sufficiently to cover 

 the stumps of branches left, many years must 

 elapse j these stumps must become rotten ; 

 and consequently the timber will be useless, 

 and probably the plant itself may be killed. 



r JFiG. 3. Represents a grove, or an ordinary plantation 

 hardwood tree,' of ten years of age, clothed 

 with a sufficient number of branches to secure 

 the extension and enlargement of the bole.
