22 REPORT OF OFFICE OF EXPEHTMENT STATIONS. 



it j)ossiblo to prive more attention to publications relating? to rural 

 engineerin<r. rural economics, and agricultural education. The Office 

 has also arranged to render more efficient aid to the Association of 

 American Agricultural Colleges and Experiment Stations in its 

 studies relating to instruction in agriculture and extension work. 



The experiment stations in Alaska, Hawaii, and Porto Rico have 

 been conducted, as heretofore, under the direction of this Office, and 

 the special investigations on the nutrition of man and on irrigation 

 and drainage have been continued lai'gely in cooperation with the 

 experiment stations, educational institutions, and other agencies in 

 different States and Territories. The educational work of the Office 

 in promoting farmers' institutes and instruction in agriculture in 

 secondary and elementary public schools has grown beyond the re- 

 sources of the Office. The work of the year has shown clearly that 

 there are several ways in which the Office can be of' much greater 

 assistance in the extension of educational facilities for farmers and 

 farmers' children as soon as funds are i)rovided for this work. 



The Office transferred the major portion of its exhibit in the Gov- 

 ernment building at the Louisiana Purchase Exposition to the Gov- 

 ernment building at the Lewis and Clark Exposition, Portland, Greg. 



The demand for the j^ublications of this Office is shown in the 

 report of the Chief of the Division of Publications for 1905, who 

 states that 184 publications of this Office were rej^rinted during that 

 3'^ear, in editions aggregating 1,788,050 copies. 



EXPERIMENT STATIONS IN ALASKA, HAWAII, AND PORTO RICO. 



In Alaska experiment stations were maintained at Sitka, Kenai, 

 Copper Center, and Rampart, and cooperative experiments were con- 

 ducted at a numl)er of points. The results of the year, Avhile some- 

 what disappointing in the interior on account of an unfavorable 

 season, were nevertheless generally encouraging. Vegetables of ex- 

 cellent quality have been matured in many parts of Alaska. En- 

 couraging results were had in grooving early maturing fruit trees at 

 Sitka. Barley, oats, and rye matured in latitude G5° 40' N., and 

 some progress was made in starting animal-husbandry work at Kenai. 



In Hawaii much progress was made in the erection of buildings 

 and the improvement of facilities for station work. Experiments 

 with forage crops and tobacco have been so successful that work 

 along these lines will be extended, and it is apparent that there are 

 new possibilities in the agricultiire of Hawaii in this direction. The 

 investigations of this station in chemistrv and entomologv have been 

 important and have attracted much favorable attention. 



In Porto Rico repeated experiments with vegetables have resulted 

 in splendid success with crops that were formerly failures. The 

 work with citrus fruits, cacao, and rubber is being continued and ex- 

 tended, as are also the experiments with coffee. The experiments
