124 EEPORT OF OFFICE OF EXPERIMENT STATIONS. 



The work of this station has progressed exceedingl}^ well, consid- 

 ering the limitations under which it has been carried on. Its sup- 

 plies to a large extent must be obtained from San Francisco, and tho 

 special agent has had but one skilled assistant during the time when 

 much of the pioneer work was in progress. The people of Guam 

 appear interested in the Avork and are readily adopting new crops 

 and methods when their superiority is shown. 



HAWAII. 



Hawaii Agricultural Experiment Station, Honolulu. 



Under the supervision of A. C. True, Director, Office of Experiment Stations, 

 United States Department of Agriculture. 



E. Y. Wn.cox, Ph. D., Special Agent in Charge. 



A new office and library building was erected during the past year 

 from funds supplied by the Territor}^ of Hawaii. This building gives 

 better library facilities than the old one, and in addition contains 

 offices for the special agent in charge, clerical force, entomologist, and 

 agronomist. The concrete building formerly used as office building 

 and chemical laboratory has been remodeled and is now wholly 

 occupied as laboratories for the chemist and horticulturist. 



By an Executive order of March 25, 1910, the land on wliich the 

 principal buildings are situated was transferred from the Navy De- 

 partment to the Department of Agriculture, and the cultivated area 

 was extended by the clearing of about 10 acres at an elevation of 

 apjjroximately 250 feet. Most of this new area has been planted to 

 tropical orchard crops of various kinds. 



The principal lines of work are conducted with a view to diversify- 

 ing the agriculture of the Hawaiian Islands. The agronomist has 

 continued his work with cotton, experiments being carried on prin- 

 cipally with Sea Island and Caravonica types, which are planted as 

 perennials. The results thus far obtained have been so successful that 

 more than 500 acres were planted during the past year for the com- 

 mercial production of fiber. The experiments with this crop include 

 pruning, propagating, fertilizing, and cultivation. The work begun 

 some years ago Avith rice has been extended, the agronomist visiting 

 Japan for the purpose of stud^dng the rice industry in that country, 

 and also for the introduction of varieties of Japanese rice. Some 

 of the tj'pes introduced liaA'e appeared adapted to Hawaiian culti- 

 vation, and the grain is better suited to the demands of the Japanese 

 population. The fertilizer experiments with rice, which have been 

 carried on in cooperation with the chemist, have demonstrated that 

 the fertilizers should be applied before planting and not with the 

 irrigation water during the growth of the plant, as is the usual prac- 

 tice. It has also been found that ammonium sulphate is a better
