 horticukure in the islands an outlet for the surplus must be pro-

The Hawaii Station is making considerable progress in aiding in 

 the diversification of the agriculture of the islands. Its investiga- 

 tions have shown the possibilities of new industries and in a number 

 of instances individuals have undertaken new enterprises. The in- 

 creasing demands made upon the station for its publications and for 

 scientific assistance show that it is being recognized as an important 

 factor in the development of the country.

The work of the Hawaiian Sugar Planters' Station has continued 

 along the lines of previous years. The division of pathology and 

 physiology has made a thorough study of the root disease affecting 

 cane and measures have been formulated for effectively combating 

 this fungus. Considerable attention has also been paid to cane di^ 

 eases of lesser importance. The division of entomology has con- 

 tinued its efforts toward checking the ravages of the leaf hopper 

 through the introduction and distribution of parasites. The efficacy 

 of these methods has been strikingly demonstrated through a radical 

 reduction of the damage by the hoppers, and while further work 

 will be pursued along this line a large part of the time of the ento- 

 mological staff will be concentrated on the eradication of the borer 

 and other insects. 



The division of agriculture and chemistry has confined its atten- 

 tion, as formerly, to questions dealing with the agriculture of cane 

 and with sugar technology. A large j)art of the field work has been 

 devoted (o the ))r<)pagation and selection of .seedling canes. Ninner- 

 ous substations have been established on the various islands and 

 tests are being conducted to determine the relative economy of dif-
