 Inspector. 



Honolulu, T. H. Dec. 31, 1905. 

 To the 



Honorable Board of _ Commissioners of 

 Agriculture and Forestry, 

 Honolulu, T. H. 



Gentlemen : — I herewith present a synopsis of the agricul- 

 tural-horticultural quarantine work performed by your officials 

 for the calendar year 1905. The value and importance of the 

 above work can only be judged from the experience of the 

 Islands in the past, as it is a well known and conceded fact 

 that all the injurious insects and diseases of plants and trees 

 are introduced species that have entered upon plants from 

 other countries. It would be utterly impossible for such 

 pests to enter this Territory by natural distribution of their 

 own migration. From the isolated position we are in, if the 

 quarantine had been instituted earlier in the history of the 

 country, it would have remained a paradise free from such 

 pests, for with inspection, disinfection, or fumigation, it would 

 have been practically impossible for the vast hordes of de- 

 vastating insects and diseases to have secured lodgement here. 



When we take into consideration that our loss from insects 

 alone in the United States amounts to four hundred millions 

 of dollars annually, principally from imported insects, we feel 

 that the above is an under estimate, when we consider that our 

 own "Hawaii nei" lost in one crop (sugar) two years ago over 

 three millions of dollars by the depredations of an imported 

 pest. This was a serious loss for one year from such a small 

 insect as the "cane leaf-hopper" {Perkinsiella saccharicida, 

 Kirkaldy). Your Board, with the co-operation of the Ha-
