for the purpose of studying the action of different forms of lime on 

 nitrification and the effect of different fertilizing elements, alone and 

 in combination, on the nitrogen in the soil and that supplied in the 

 fertilizer application. 



The usual control tests were made at a number of mills during the 

 grinding season and detailed reports were submitted to the parties 

 interested. During the year ending September 30, 1910, 43 compiled 

 statements of weekly mill reports were issued by the station. 



The results secured at the plantation substations brought out the 

 distinct merits of Demerara seedling 1135. This cane gave remark- 

 ably good results at all the substations, at three of which it surpassed 

 in yields the best of 20 plats of the standard cane and Lahaina and 

 Yellow Caledonia grown for comparison. A number of plantation 

 substations were started or projected during the year. In an experi- 

 ment conducted for the purpose of securing suitable leguminous crops 

 for green manuring in the various districts of the islands, 110 vari- 

 eties were planted in the station fields during the year, and of these 

 26 gave promise of warranting their further trial on a larger scale. 

 The genera which appeared to furnish the best varieties for this pur- 

 pose were Stizolobium, Dolichos, Canavallia, and Vigna. 



The following publications of the station not noted in last year's 

 report were received during the year: Division of agriculture and 

 chemistry. Bulletin 30, The Influence of the Structure of Cane on Mill 

 Work in Sugar Factories; division of pathology and physiology. Bul- 

 letin 6, Fungus Maladies of the Sugar Cane ; division of entomology. 

 Bulletins 6, The Hawaiian Sugar Cane Moth {Ereunetis flavistriata) ^ 

 with An Account of some Allied Species and Natural Enemies; 7, 

 Army Worms and Cutworms on Sugar Cane in the Hawaiian Islands; 

 and 8, A Bibliogi-aphy of Sugar-Cane Entomology. 



This station receives no direct aid from the Federal appropriations. 



W. J. Hartung was appointed an assistant chemist to succeed F. T. 

 Dillingham and F. Evans was appointed agriculturist to replace 

 E. G. Clarke. R. C. L. Perkins, director of the division of ento- 

 mology, returned from a year's leave of absence in May. A plant 

 house, 17 by 25 feet, with screen sides and glass roof, was erected for 

 the isolation of plants in infection experiments by the division of 

 plant pathology.
