sheep are in progress. The work witli hogs was discontinued on 

 account of disease. The third year's work on the production of baby 

 beef was completed and the results are soon to be published. Two 

 years' experiments in the economical wintering of work horses were 

 finished, and a preliminary report suggests the use of a variety of 

 cheap yet efficient feeds in place of oats and timothy hay. The 

 third year's work with feeding succulents to sheep showed no 

 particular advantage over feeding roots when the extra expense is 

 considered. Breeding experiments with sheep and cattle were also 

 carried on. 



In the dairy department demonstration experiments were made of 

 the value of well-bred dairy cows, the care of milk on the farm, and 

 the production of sanitary milk. The third year's performance of 

 the grade dairy herd was recorded. The poultryman completed the 

 second year's trial of three types of poultry houses designed as models 

 for farm use, and studied in addition the relative value of various 

 feeds for young chicks and the relation of age and breeding of pullets 

 to egg production. 



The horticulturist conducted experiments in potato spraying, test- 

 ing fertilizers for apple, peach, and grape growing, comparing 

 sucker and pruning wood of apples for propagation, soil sterilization 

 of greenhouses, peach pits as a means of disseminating disease, lime 

 and suli)hur as a summer spray, and cover crops for vineyards in 

 conjunction with commercial fertilizers. 



Plant breeding and culture experiments were in progress with 

 practically all the important crops. The imj^roved strains doveloj:)od 

 in this work were tested throughout the State in cooperation with the 

 recently established Experimental Union. 



The extension work is organized and managed under state appro- 

 priations and during the year 3 men were constantly maintained by 

 the college for giving instruction and demonstrations in live-stock 

 management, horticulture, and field crops. Tlie Experimental 

 Union, comprising over 200 members, engaged in cooperative work 

 in crop testing and soil studies. During the year, 872 bacterial cul- 

 tures for leguminous crops were sent out to farmers from the bacteri- 

 ological department, which also furnished virus and serum for 

 immunizing over 2,000 hogs. In the extension work in animal 

 husbandry efforts were directed mainly toward the organization of 

 cooperative breeders' associations, and during the first six months of 

 the year ten associations were formed representing 2,100 cows, and ."il 

 registered sires were purchased. 



The j)ublications of the station received during the year were as. 

 follows: Bulletins 251, Insects of 1007: 252. Fertilizer analyses: 

 253, Can the general farmer afford to grow apples; and suggestions 

 on improving and spraying apple orchards; Special Bulletins 42,
