Kentucky Agricultural Experiment Station, Lexington. 



Department of tbe State University. 



M. A. ScovELL, M. S., Ph. D.. Director. 



The work of this station was in general along the lines followed in 

 1908. Out of the fees arising from the fertilizer and feeding stuffs 

 control a farm ccsting $7,000 was purchased and a new piggery with 

 numerous feeding lots was provided. Other general and minor im- 

 provements were made during the year in the e.xperimental fields and 

 about the station buildings. Facilities for examining drugs under 

 the state law were provided in the food laboratory of the station. 

 W. H. Scherffius, head of the agricultural division, resigned to take 

 up work in South Africa, and L. A. Browne, of the North Dakota 

 Station, was added to the staff as chemist in the drug division. 



The Adams fund projects were continued as originally planned. 

 The number of broods and some other facts in the life history of 

 the corn earworm have been worked out. and the results are nearly 

 ready for puljlication. Additional data were obtained in support 

 of the conclusions as to the identity of the organisms causing nodules 

 on alfalfa and sweet clover and the identity of the organisms on red 

 and white clover. Satisfactory protjf was also secured of the iden- 

 tity of the organism causing nodules on alsike clover with that on 

 red and white clover. The forms of organisms on coAvpeas and soy 

 beans were found distinct from those on the clovers. Some pre- 

 liminarv work was begun on the studv of milk fever in dairv cows, 

 and this is to be carried forward as circumstances permit. Some 

 progress in soil studies is reported, much of the time having been 

 given to the study of methods of determining potash. 



The activities under the Hatch and other funds included experi- 

 ments with breeding, growing, and curing tobacco; tests with forage 

 plants of various kinds; special studies on alfalfa and soy beans; 

 crop-rotation trials; breeding and culture experiments with wheat; 

 corn, barley, oats, and potatoes; soil studies; studies of insect and 

 fungus pests: pig breeding and feeding: hog-cholera immunization, 

 and related lines of work. Tests of various sheep dips against scab 

 were reported in a bulletin published during the year, in which the 

 use of dips made of lime and sulphur, tobacco and sulphur, or one of 

 the coal-tar dips was recommended. Tobacco or coal-tar prepara- 

 tions were found to be more effective than the lime and sulphur 

 dip in destroying the sheep tick or louse, in addition to being a 

 satisfactory treatment for sheep scab. In tobacco experiments it was 

 found that phosphates gave appreciably better gains that potash salts 

 on soil typical of much of the toi)acco soil of western Kentucky, and 

 that nitrates tended to reduce the crop by causing a less perfect 

 stand.
