In agronomy the breeding of cereals on the centgener plan was 

 conducted with reference to Mendelian characters, and variety tests 

 were made with oats, wheat, corn, sorghum, peas, soy beans, marrow 

 cabbage, and other crops. Selection work was done with corn, tim- 

 othy, alfalfa, and varieties of alfalfa, vetches, and grasses were grown 

 in cooperation with this department. Dry farming work was carried 

 on at Ritzville, including experiments on spring versus fall cultiva- 

 tion and other work relating to the treatment of the land to retain 

 moisture, special attention being given to the effect of continuous 

 cropping and fallowing. Rotation experiments were also in progress. 



The botanist studied the injury by Bordeaux mixture to plats and 

 conducted spraying experiments with lime-sulphur mixture at Che- 

 halis for apple scab and other fruit diseases. Much attention was 

 given to high-pressure sj)ra3dng, and the results secured were favor- 

 able. The study of the distribution of the fungus diseases in the 

 State was continued. 



The horse-feeding experiments conducted by the animal husband- 

 man included the past season the feeding of different combinations 

 of timothy and oats, wheat hay and oats, and alfalfa alone or with 

 barley. Pig-feeding experiments were made to compare tankage 

 with wheat. 



The entomologist studied the control of the codling moth in orchard- 

 spraying experiments at AValla Walla and Garfield. Tests were also 

 made with lime sulphur, zinc arsenite, and iron arsenate as a means 

 of control. 



The legislature of 1911 passed a stallion registration law requir- 

 ing that all pure-bred and grade stallions and jacks, kept for public 

 service within the State, shall be registered with tiie professor of 

 animal husbandry of the State college and provided a registration 

 fee. All moneys collected are to be expended under the direction 

 of the board of regents, and the annual report of such expenditures 

 is to form a part of the annual report of the experiment station. 



Preparations were made to separate administratively the farmers' 

 institute and extension work from the experiment station, and be- 

 ginning with October 1, 1911, all official connection of the director 

 of the station with the administrative work of this department of 

 the college ceased. During the past year members of the experiment 

 station staff gave a limited amount of time for lecturing at farmers' 

 institutes and on farm-demonstration trains. 



The publications received from this station during the year were 

 as follows: Bulletins 90, Forest, Shade, and Ornamental Trees in 

 "Washington; 91^ Wheat and Flour Investigations; 92, Cherries in 

 Washington; 94, Potato Investigations; 98, Commercial Fertilizei-s ; 

 Popular Bulletins 29, The INIilling Quality of AVashington Wheats, 

 II; 30, Spraying for the Codling Moth; 31, Clover in the Palouse
