208 OBSERVATIONS ON THE DISEASES, &c: 



if you would be willing to undertake to apply it, or superintend 

 or direct the application of it by persons properly instructed by 

 yourself, to any number of trees that might require it in any 

 of the royal forests ? 



4. In case there should be occasion to apply such a remedy 

 to a very considerable number of trees in the state above de- 

 scribed, we wish to know, as nearly as possible, what expence 

 the application would be attended with, by the hundred, or 

 thousand, or any given number of trees, including labour, ma- 

 terials, and every incidental expence ? 



We shall be glad to receive an answer to these enquiries 

 with all convenient speed, and are, 



Sir, 



Your most obedient Servants,

To the Honourable the Commissioners of the Land Revenue, 



Uoyal Gardens, Kensington, April 24, 1789. 



HONOURED SIRS, 



TTo the letter you have been pleased to honour me with, I 

 beg in general to say, that, from many years attention to fruit 

 and forest-trees, I have observed every wound, bruise, or in- 

 jury ; even the wanton cutting of the initials of a name on the 

 bark of a tree has been attended with mischief, and has often 

 brought on the destruction of the tree, especially if old. In 

 particular I beg to say, that if a tree be young, nature will ex- 

 ert herself to recover from the injury ; but if the tree be old, it 

 will cease to grow about the injured part, will not increase in 

 size, the wound will daily increase, and in time destroy ail the 

 timber of the tree.
