weather conditions little work was done on the codling moth. Inves- 

 tigations on the life history of the alfalfa leaf weevil and means of 

 control, and studies of the amount of arsenic necessary to kill orchard 

 trees, were begun. 



In addition to the Adams fund investigations, the horse-breeding 

 work has been continued with gratifying results. The stallion regis- 

 tration law passed at the previous session of the legislature has been 

 enforced and the standard of the horses of the State is rapidly 

 advancing. 



The experimental work in dairy lines was limited, owing to the 

 proposed change from grade to pure-bred stock. Cooperative work 

 in testing dairy herds was carried on with the farmers and creamery 

 men in a number of localities, and is resulting in a gradual betterment 

 of dairy herds. Two more breeds of sheep were added to the live- 

 stock equipment and the sheep-feeding experiments were continued. 



Investigations in arid farming were continued, and extended to in- 

 clude more cooperative work with different divisions of the Bureau of 

 Plant Industry of this Department. Scientific work was discontinued 

 at all of the substations except the one at Xephi. Forty acres more 

 of land have been secured adjoining the original plat and all of the 

 work in plant breeding transferred to this place. A large number of 

 varieties of wheat and other farm crops are being tested and pedigree 

 breeding methods employed on the most valuable varieties. Im- 

 proved strains of winter oats and barley have been developed and are 

 now being distributed, and considerable improvement has been made 

 over the wheats formerly used in arid farming. The arid farming 

 interests of the State continue to develop with wonderful rapidity. 

 Thousands of acres are being taken up annually, and in some of the 

 more fertile locations homes are being established on the farms. 



The station took over the work in sugar-beet breeding and testing 

 formerly carried on in cooperation with the Bureau of Plant Indus- 

 try, and more thorough methods of j^edigree breeding are being 

 employed. 



Irrigation experiments were continued in modified form on the 

 Greenville farm in cooperation with this Office. The larger part of 

 the work was, however, transferred to cooperative experiments with 

 farmers in different sections of the State in order to test the water 

 requirements of different soils. Orchard irrigation was also taken 

 up in cooperation with private orchardists, and an extended investi- 

 gation is planned to ascertain the effect of different amounts of water 

 on fruit produced, quality, size, color, size of pit, keeping quality, 

 and other factors of successful fruit production. 



The drainage investigations, also in co()[)eration with this Office, 

 were continued, several of (he jirojects having licen closed uj) and 

 turned over to the communities in satisfactory condition. One or two
