OF FRUIT AND FOREST TREES.

so good as to inform us, as nearly as you can, whereabouts 

 would be the expence of such application, including labour, 

 materials, and all incidental charges, but exclusive of any re- 

 ward to yourself for disclosing the composition for the benefit 

 of the public, which we conceive should be given separately. 

 We are. Sir, 



Your most obedient Servants, 



JOHN CALL, 

 JOHN FORDYCE. 



Mr, William Forsyth. 



No. 3. 



To the Honourable the Commissioners of the Land Revenue. 



Royal Gardens, Kensington, April 28, 1789, 



HONOURED SIRS, 



I PRESUME I need not again assign the reason why I 

 omitted in my former letter, mentioning the expence which- 

 will be incurred by cutting out the injured Darts of the trees, 

 and the application of my composition. I have endeavoured 

 to think of every probable charge that will accrue ; and, upon 

 an accurate calculation, am convinced it will not exceed six- 

 pence per tree. It may not be improper here to observe, that 

 this calculation includes the labour of the men for the opera- 

 tion ; 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.
