THE jHAWAIIAN 



rORESTER I AGRICULTURIST 



Vol. XL NOVEMBER, 1914. No. 11 



An introduction to some of the rare scenic resources of the 

 Island of Oahu is furnished in the ilhistrated account, in this 

 number, by Professor ]\IacCaughey, of a biological expedition 

 over the Koolau mountains. 



Gratification will be felt by all who have taken an interest in 

 the fruit fly control campaign on reading the report of the inves- 

 tigations made by Mr. Giffard and Dr. Back of the extent to 

 which the Silvestri parasites have become self-colonized in the 

 coffee and fruit fields of Kona. It is pleasing in itself to know 

 that the expedition of the Italian scientist to Africa last year has 

 not gone for naught, through failure of the first part of the 

 problem which might have happened by the dying of the original 

 parasites he brought here, but the keenest satisfaction is found 

 in the evidence now presented that not only have the beneficial 

 insects lived to propagate their kind, but their progeny appears 

 to be doing effective work in keeping" down the pest. JNIr. Gif- 

 fard's observation that the infestation of coffee berries in Kona 

 is now fifty per cent less than a year ago is most encouraging 

 testimony. 



Besides the usual record of pests kept out of the Territory, the 

 report of the superintendent of entomology for September con- 

 tains encouraging data on fruit fly control. 



Nearly thirty thousand plants distributed in one month, to the 

 general public and corporations, as reported for September by 

 Mr. Haughs, form a record for the division of forestry which 

 should be a matter of pride to the entire Territory. 



Hint of the possibility of a billion-dollar reservoir in the region 

 of Kahuku, Oahu, given in the report of the superintendent of 

 hydrography for September, is just one inkling of what the 

 scientific measurement, control and utilization of the water re- 

 sources of these Islands mean to their industrial, commercial and 

 social development.
