tically dead. Later the branch died back nearly 18 inches though the Hce 

 remained uninjured. 



(2) . Carbolic acid (c.p.) 3^ oz. 



Lime sulphur (1-40) 1 gal. 



The addition of carbolic acid to the lime sulphur produced a fine 

 yellowish precipitate but no other change was noted. This mixture was 

 applied to several badly infested trees and the results obtained were exactly 

 identical with those from pure water and carbolic acid. 



Although C.P. carbolic acid was used it seems to me that its insectici- 

 dal value would be as high as the commercial product. From several 

 experiments along this line I am led to conclude that the addition of carbolic 

 acid to a soap solution does not seem to increase its insecticidal value.
