rice, and cotton; fertilizer, rotation, and culture tests with various 

 crops; and tile-drainage studies. Breeding work with nine standard 

 varieties of corn was carried on for the purpose of combining desir- 

 able features to meet Arkansas conditions. Observations were also 

 made on dates and rates of planting, cultivation in ditferent ways, 

 the use of fertilizers, the vitality of seeds, and on the character of 

 plants produced by seed embodying various breeding factors. Fifty 

 varieties of cotton were tested with reference to yield, quality, and 

 length of fiber, early maturity with reference to boll-weevil resistance 

 and adaptability to ditferent sections of the State. Cultural and 

 breeding work with cotton was also carried on. Several varieties 

 each were grown of wheat, barley, and oats for both fall and spring 

 planting to determine the most desirable foundation stock. 



The work with rice included a test of 40 varieties, various culture 

 tests, breeding experiments, and a study of methods for the eradica- 

 tion of red rice and for the control of rice blight. Experiments were 

 also made with a large number of leguminous forage crops and with 

 different methods of crop rotation and soil treatment. The depart- 

 ment of entomology had charge of inspection of nursery stock. Co- 

 operative experiments in spraying for San Jose scale indicated that 

 kerosene emulsion may be successfully used to hold the pest in check 

 over summer until lime-sulphur wash can be used. Observations on 

 the occurrence and outbreaks of injurious insects in the State were 

 made, and special attention was given to the life history and methods 

 of control of the plum curculio and the peach-tree borer. 



Tick eradication was successfully prosecuted during the year in 

 cooperation with the Bureau of Animal Industry. This work was 

 under the control of the station in the northwestern section of the 

 State and of a commission in the northeastern section. An assist- 

 ant of the station veterinarian was in charge of the field work. The 

 veterinarian assisted in the eradication of tuberculosis from two 

 local centers in the State, and made post-mortem demonstrations at 

 the State fair on tuberculous animals. Of 363 farms examined, 42 

 were found to own tuberculous cattle, and of 5,227 cattle tested 69 

 proved to be tuberculous. 



The dairy department increased its facilities during the year by 

 renting an additional 65 acres of land and putting up some buildings. 

 Experiments with silage and soiling crops failed on account of an 

 unfavorable season. Work was continued on the factors controlling 

 moisture in butter, cream ripening versus butter ripening, methods of 

 testing cream, and cooperative herd testing. Experiments in feeding 

 cottonseed meal to brood sows were continued, and some tests were 

 made of the effect of wide and narrow rations on egg production.
