tests of varieties in breeding of wheat and oats, experiments with 

 winter oats, barley, cowpeas, soy beans, alfalfa, and other forage 

 plants, tests of methods of seeding, and studies in soil fertility. In 

 1 county of the State corn yields have been increased IG} bushels per 

 acre and clover yields If tons on each acre by the application of results 

 discovered by the station. Good soil management on one of the 

 experiment fields increased the clover yield from one-half ton to 2 

 tons per acre, and the net profit by $G. On the soil experiment fields 

 in southwest Missouri the station has shown that corn may be in- 

 creased from 20 to 45 bushels per acre. In the same locality the wheat 

 yield has been increased 12 bushels per acre. In soil experiments car- 

 ried on in northeast Missouri the yield of wheat was increased by 15 

 bushels per acre, with a corresponding increase in the net profit. 



Experiments were made on the effect of high and low rations on 

 butter-fat production, and experiments were begun on the trans- 

 mission of tuberculosis from cattle to pigs. The college inocu- 

 lated 40,000 hogs during the past year, 85 per cent of which were 

 saved from hog cholera. 



Fertilizer inspection and miscellaneous analyses were made by 

 the chemical department. 



The cooperative experiments of the station in 1910 were quite ex- 

 tensive. In 105 counties of the State 366 persons cooperated with 

 the central station at Columbia in experiments to determine the 

 best methods of farming. In carrying forward this work 3,000 dif- 

 ferent packages of seed were used and more than 20,000 pounds of 

 fertilizer. Former students of the college of agriculture and farm- 

 ers of the State have organized the Missouri Experiment Associa- 

 tion, which has for its fundamental purpose cooperative investiga- 

 tions with the college and station. The results secured have already 

 demonstrated that alfalfa can be grown successfully in every county 

 of the State, and that the best varieties of corn from Missouri are 

 Boone County White, Reid Yellow Dent, Johnson County Wliite, 

 and St. Charles AVliite. The horticultural investigations have in- 

 dicated the best fertilizers for orchard, bush fruits, and vegetables. 

 Cooperators in dairying have, under the direction of the college and 

 station, increased their profits, in some cases more than 20 per cent. 

 Field experiments on typical soils of the State in cooperation with 

 the soil survey were continued and extended, and are now conducted 

 on fields in 96 of the 114 counties of the State. The soil survey was 

 continued, partly in cooperation with the Bureau of Soils of this 

 department. 



Two additional county demonstration farms were organized dur- 

 ing the year under the act of 1907, one at Clayton, St. Louis County, 

 and the other near Lewiston in Lewis County, with E. L. Newton 

 as superintendent. The chief lines of work undertaken at these
