inmost bark, as in the case of vermin. If 

 the disease penetrate to the wood, and go 

 all round, in the same circle or parallel, 

 that tree or branch has no chance to live, 

 it ought therefore to be cut off. If, how- 

 ever, any part of the wood is fresh, it may 

 be preserved by putting in a piece of fresh 

 bark, from another part of the tree, or from 

 another tree ; or it can be preserved by 

 another substance, such as a piece of linen 

 rag, to conduct the sap till a new bark is 

 generated. 



Peeling cannot be of so much service to 

 wall trees, in regard to the vermin, they 

 mostly residing and depositing their ova in 

 the wall, and not in the bark of the tree j 

 but it is of equal service in regard to the 

 constriction.
