 and, upon an accurate calculation, I am convinced 

 it will not exceed sixpence per tree. It may not 

 be improper here to observe, that this calculation 

 includes the labour of the men for the operation ; 

 the Composition, and the application of it ; and 

 also an after review, that the healing of the trees 

 is going on well ; but I should also observe, that in 

 this expence I have not put down any thing for 

 myself, leaving that wholly and altogether to your 

 further consideration. 



I am, honoured Sirs, 

 With great respect. 



Your most obedient, 



Humble Servant, 



William Forsyth.
