view of the facts given by Mr. Green there is every reason to be- 

 lieve that such would have been the case. There seems also 

 some basis to believe that the bug was responsible for the dis- 

 semination of the fungus. The two coffee enemies probably aided 

 each other materially. While our Cercospora coffeicola does not 

 seem to be as injurious as was H. vastatrix, who can tell what its 

 effects would have been when assisted by the "green-bug?" Nor, 

 as stated in my report, is the fungus disease of the bug, referred 

 to by Mr. Green and Dr. Evans, known to exist in Hawaii. 



And finally, as to the practicability of kerosene emulsion or 

 any other spray against an enemy of coffee in Hawaii : Had Dr. 

 Evans seen the conditions under which coffee grows in Kona, 

 for example, he would have not ventured to offer the kerosene 

 emulsion remedy. As much coffee grows (wild, uncultivated, I 

 mean) in Kona, as is under rational cultivation. Should the 

 "Green-bug" have gained a foothold in Kona, the most effective 

 wash would have been no more practicable there than in the sugar 

 cane fields against the leaf hopper. 



Dr. Evans would have profited either by reading the December 

 (1905) Forester or by consulting an entomologist before writing 

 his opinion.
