which indicated that the beetle had been here for some time. An 

 elderly Hawaiian living at the head of a small valley we visited 

 informed us that he found the beetle three seasons ago. As 

 mangoes have been freely sold and distributed from the infected 

 districts, I fear that it has now been scattered over this island 

 and probably carried to others of the group. As the mango trees 

 loaded with fruit in the infected district overhanging the public 

 thoroughfare and a district school is located in the midst every 

 facility has been given for the pest's distribution. Our in- 

 spection extended from Palama valley, in Honolulu, to within a 

 mile of Pearl City, wherein we found the pest, so I feel confident 

 from the large size of the trees and character of the soil and un- 

 dergrowth that it will be impossible to stamp it out of the Terri- 

 tory, even by the destruction of the present or two succeeding 

 crops, so on that account I would not advise your Board to ex- 

 pend any money in the attempt. 



While the weevil is found inside there is no evidence of where 

 it entered and no damage appears to be inflicted upon the fruit 

 other than destroying the germination of the seed. 



BENEFICIAL INSECTS. 



In my last report to you I referred to the receipt of several 

 beneficial insects from Prof. Koebele, which were turned over to 

 Mr. Kotinsky for propagation. The past two weeks he has 

 liberated two colonies our doors and has others in breeding jars 

 ni the office. 



Respectfully yours,

CASTOR OIL. 



The uses of castor oil are manifold. Besides its ordinary 

 medicinal use as a laxative or purgative, if well rubbed into har- 

 ness it makes the leather water-proof, keeps it from being touched 

 by cockroaches or rats. It can be used instead of soap in making 

 kerosene emulsion for spraying or washing orange trees. It is a 

 good insecticide and fungicide if used with one part of kerosene, 

 one part of sweet oil to one part castor oil. This will kill hair 

 lice, cure ring-worm and mange on animals, cure scaly-leg on 

 fowls and also mild cases of yaws in fowls if painted on the 

 eruptions, and will kill ticks, fleas and bugs. — Journal of the
