He again sent samples of a twig to which Mr. Kotinsky re- 

 plied on October 30th, "that all the scales on the twig were 

 dead, from which I conclude your dipping in soap solution was 

 effective." The next visit of one of your entomologists to 

 that island a thorough inspection will be made to see that it 

 has been completely exterminated there. 



From Japan came fourteen small tea plants on which I found 

 traces of a white wax scale (Ccroplastcs) ; after destroying any 

 that had evidence of that scale the others were fumigated with 

 hydrocyanic acid gas and will be held in quarantine to watch 

 developments. 



A Customs inspector intercepted a small package of rolled 

 pearl barley being taken from the Japanese training ship "Ara- 

 gawa." Acting Collector Stackable notified me and Mr. Austin 

 and I visited the training ship and looked through the stores 

 and found the above grain infested with ''rice weevils" (Calan- 

 dra oryza). We brought the matter before the officer of the 

 day and he issued orders to the sailors and members of the 

 crew not to take any of that barley ashore. This is a cos- 

 mopolitan beetle and is found on the Islands.
