plemented by oat hay and such root crops as turnips and ruta-bagas, 

 if it were practicable to grow them at this time, but the resources of 

 the station do not permit the necessar}' equipment of implements and 

 labor for growing these crops. 



The stations continue to cooperate quite extensively with farmers 

 and others throughout the Territory, and successful reports have 

 been received from a large number who have taken up agricultural 

 pursuits as a result of the reports previously published by the stations. 



HAWAII STATION. 



The heads of the different departments of the Hawaii Station 

 report considerable progress with their investigations and a gratify- 

 ing appreciation of the efforts of the station. 



The agronomist has continued to make rice and cotton investiga- 

 tions the main lines of work in his division. The cultural and fer- 

 tilizer work with rice is giving results of great value, and some of the 

 ordinary varieties of rice introduced by the station have been widely 

 planted with gratifying results. The variety referred to in previous 

 reports as Xo. 19 has been firmly established, and over 700 pounds of 

 seed rice of this variety was distributed to growers in 1909. This 

 variet}^ is a pure strain developed from seed obtained through the 

 Bureau of Plant Industry of this Department from Ceylon stock 

 grown at Georgetown, British Guiana. As this rice has some very 

 superior qualities and the difficulties attending its economical milling 

 have been overcome, its wide cultivation is soon to be expected. The 

 experiments with fertilizers are being continued at the station and 

 also in cooperation wdth some of the largest rice growers to determine 

 the effect of certain fertilizing elements and the most advantageous 

 times for their application. The methods of fertilizing the rice crop 

 described in previous reports have been put in application and have 

 resulted in more than doublino; the vield of ordinary rice lands. A 

 study is being made in cooperation with the chemist on the constitu- 

 ents removed from the soil by the rice plant at different stages of its 

 growth and the effect of the removal of the fertilizing elements on 

 the physical character of the soil. Cooperative experiments with 

 upland rice have shown that this crop can be depended upon for an 

 excellent quality of grain hay, thus furnishing a much-needed local 

 Fupply of forage. 



An unusual interest has been manifested in the cotton experiments 

 of the station. These were l)egun in the spring of 1908 and are being 

 carried on with a considerable number of varieties representing Up- 

 land, Chinese, Egyptian, Sea-island, and Caravonica cottons. All 

 these varieties have been found to grow as perennials, and experi- 

 ments have shown that by pruning the fruiting season may be con- 

 trolled and that throu/^h the removal of the old w(X)d considerable
