30£ USE OF lOfiACCO "WATER. 



stroying insects on fruit tree?, T trouble you with the result 

 of my experiments last year, as it will strongly tend to con- 

 firm my representation to you on the subject, in the spring of 

 1802. 



Experiments Being from home in the early part of last season, when 



with tobacco ° . '. r 



water on fruit W trees were putting: forth their shoots, I was prevented

found on my return several large peacTi and nectarine trees, 

 against a west wall in my garden, so wholly diseased, that 

 not a leaf was to be found on them, but which was curled 

 pp and full of insects. The trees were then well covered 

 with fruit of nearly the size of a hazel nut ; but being des- 

 titute of leaves to shelter them, I despaired of saving any, 

 and was apprehensive of losing even the trees. I imme- 

 diately prepared some tobacco water, of more strength than 

 usual, and applied it by sprinkling it very forcibly from a 

 brush, and in two or three days I could perceive the insects 

 were nearly all killed. I then renewed the application ; 

 and in about a week after I had the diseased leaves picked 

 off, and repeated the wash, and found it to be thoroughly 

 effectual. The trees completely recovered, put forth the 

 finest shoots possible, and ripened an immense quantity of 

 fruit in the highest perfection.

 every insect, that ravages on the leaves of trees and plants 

 of all descriptions. And I conceive its benefits may be in-

 exterminate in hop plantations those insects, which are so 

 destructive to the plants.
