advice was sustained by Dr. Cobb and Mr. Lewton-Brain, to 

 cut away and destroy all the affected portions of vines. To 

 make cuttings by means of a tool, disinfected in a 10% solu- 

 tion of Formalin and to keep the vines covered with Bordeaux 

 mixture, the standard universal remedy against all fungus 

 diseases. At my suggestion Mr. Woods has sprayed his vines 

 with this mixture some six weeks previous to my visit, ana 

 despite the daily rains the mixture was quite evident upon 

 the vines, both upper and under surfaces when I saw them. 

 If this application be made every two or three weeks the vines 

 will remain completely covered .by this coat of armor, proof 

 against fungus onslaughts from without. After instructing 

 the gentlemen in the principles involved in the preparation of 

 this mixture, I left with them the chemicals (10 lbs. of blue 

 stone and 10 lbs. of unslaked lime in a soldered tin) for the 

 impending battle against the menacing fungi. 



BEOWN EYE SPOT (Ccrcospom cafricola, B. & C.) AND OTHER 

 COFFEE DISEASES IN KONA. 



The brown-eye spot disease seems to extend its ravages 

 farther and farther afield. The coffee growers estimate their 

 loss at about 25% of their present crop owing to this pest. If 

 this disease is altogether responsible for this terrible loss, 

 terrible because of the present low prices on coffee, and if, as 

 elsewhere suggested, the prevalence of this disease is due to 

 the presence of Siphanta, also known as Torpedo-bug, we hope 

 that by the aid of the Siphanta egg parasites, this evil will be 

 eliminated. Among the first colonies of this parasite to be 

 sent out went to Kona, and while it was too soon when I was 

 there to determine whether the insect is established, we are 

 confident that it is, and hope for good results from its work. 



A number of coffee trees, often in clumps, were observed 

 dead. "Whether in consequence of this or some other disease 

 it is hard for an entomologist to tell, as insects are not re- 

 sponsible for their death. The Territory is sorely in need of 

 a plant pathologist and physiologist to clear up many of the 

 mysterious tree-growing failures. 



I may mention in this connection that the planters of Kona 

 sought my advice with reference to tlie advisability of peti-
