cane as such are much more insidious in their work on vegetation 

 than most other pests and certainly more difficult to combat. 



During this time Mr. Kotinsky has been industriously breeding 

 and distributing colonies of beneficial insects for horn flies, also 

 others preying upon scale and other injurious insects. Several 

 valuable colonies of useful insects have been received from Prof. 

 Koebele, collecting in Arizona, and now in Mexico. Other useful 

 insects have also been received from Mr. Compere from China 

 and are being attended to by Mr. Kotinsky. 



Since my return Mr. Austin and I have been almost constantly 

 employed in the fumigation of large importations of infested rice 

 from Japan (15,736 sacks). Carbon bisulphide was successfully 

 used in tight fumigating rooms on the quarantine wharf after 

 which the rice was put through the polishing machinery. An 

 extra strong application of hydrocyanic acid gas v/as applied in 

 one large room, but was not as successful as the carbon bisulphide 

 and had to again be treated with the latter fumes. The rice im- 

 porters cabled instructions to their agents not to ship any more 

 rice unless it had been treated or put through the mill. The only 

 lot received since was a few thousand sacks on the delayed S. S. 

 "Mongolia" that had sailed before receipt of the cable instructions. 

 The Collector of Customs, under instructions from the Secre- 

 tary of the Treasury, withheld delivery of the rice until it was 

 thoroughly fumigated. 



Since my last report fifty-five (55) steamers and sailing vessels 

 arrived in port from outside the Territory, bringing one hundred 

 and thirty-four thousand five hundred and ninety-four (134,594) 

 packages of fruits and vegetables. This does not include the 

 15,736 sacks of rice we fumigated. During the same period we 

 inspected one hundred and thirty-seven (137) packages by 'mail. 

 The reason for this large invoice by mail was the receipt of 

 fifty (50) packages of Cacao plants from the Department of 

 Agriculture, Washington, D. C, and thirty-five (35) packages 

 of sisal plants, (210) from the same place. The former had been 

 treated with Bordeaux mixture, but had some living mealy bugs ; 

 these and the sisal plants were fumigated here with hydrocyanic 

 acid gas. Four (4) larpge cases of plants also came in and were 

 carefully inspected and fumigated. 



Recpectfully submitted, 



ALEXANDER CRAW, 

 Superintendent of Entomology and Inspector.
