232 OBSERVATIONS ON THE DISEASES, 5cc. 



These are exclusive of many trees that were on the walls 

 before, and which have been much benefited by being dressed 

 with your composition. I am so fully aware of the excellence 

 of the composition, that I do not permit the gardener to prune 

 any plants without immediately using it. If you think these 

 remarks can be of any service, you have my permission to 

 make any use of them. 



I am, dear Sir, 



Yours sincerely,

Extract of a Letter from Thomas Davis., Esq. Author of the 

 Agricultural Survey of Wiltshire, 



June 28, 1801. 



A WAS happy in having an opportunity the other day of 

 shewing the effects of your plaster (in recovering the bark of 

 oak-trees of 4 or 500 years old, which had begun to rot up- 

 wards from the ground, and is now recovering downwards very 

 rapidly,) to Lord Spencer., who was both pleased and astonished 

 with it. 



" You may at any time refer to 7ne for proofs if you want 

 them. I made a bold experiment seven years ago on an oak- 

 tree 40 feet high and 16| feet round, worth £,^0 at least to a 

 Carpenter to cut to pieces, and such a tree as the King has not 

 ten in his dominions. There was a craze in the side of it, 

 which looked like a shake, and spoiled its beauty. I cut out 

 the bark on each side the fissure so as to make the opening 6 or 

 7 inches wide. I coated it well with plaster, and it is now per- 

 fectly united and sound."
