will consume more than is necessary for maintenance and a maximum 

 flow of milk. 



The investigations continued include, among others, those on the 

 chemical analysis of soils to determine fertilizer needs; rotation of 

 crops; experiments with wheat to increase the gluten content; breed- 

 ing Burlev tobacco to secure a type with more erect leaves and a 

 more elastic staple (PI. IV, figs. 2 and 3) ; study of insect pests and 

 diseases of cucumbers and edible mushrooms grown in hothouses; 

 study of cause of failure in growing red clover, in cooperation with 

 farmers, and study of life histories of numerous insects. The station 

 is cooperating to a considerable extent with farmers and with the 

 Bureau of Plant Industry of this Department on rotation experi- 

 ments and tests of forage plants. 



Among the studies more recently inaugurated are those on the 

 effect of artificial shade in preventing rust of celery and the mildew 

 of the cucumber, the life history and remedies for seed insects, the 

 effect of fumigation on the germination of seeds, nitrogen-fixing bac- 

 teria and their relations to leguminous plants, clover diseases and 

 insect enemies, the effect of different ingredients of fertilizers on 

 alfalfa, and the effect of inoculating the soil with nitrogen-fixing 

 bacteria from various sources. The agriculturist resigned at the 

 close of the year to accept the position of agriculturist and director 

 of the South Carolina Experiment Station, and the assistant ento- 

 mologist to accept a call from the department of agriculture of Ire- 

 land as expert on curing tobacco. 



The facilities of the Kentucky Station for research work have been 

 much improved by the completion of the new station building. This 

 is a two-story and basement l)uilding, with offices, library, and four 

 well-equipped chemical laboratories on the first floor, and with a 

 suite of rooms for the department of entomolog}' and botany, and 

 offices for the agriculturist, animal husbandman, and horticulturist, 

 and other rooms on the second floor. With its increased equipment 

 and the systematization of its field experiments, the Kentucky Sta- 

 tion is now in a better position than ever before to do useful work. 



LINES or WORK. 



The principal lines of work conducted by the Kentucky Station 

 during the past year were as follows: Chemistry; soils; analyses of 

 fertilizers, foods, and feeding stuffs; inspection of orchards and nur- 

 series; fi<'ld ex[)eriuients — hemp, tobacco, cereals, leguuies, fertilizers; 

 horticulture; plant breeding — wheat, corn, tobacco, and sorghum; 

 breeding of animals; pig feeding; diseases of plants — tomato rot; 

 entomology — the Hessian fly, seed insects, corn root-worm, tobacco 

 worm, apple-tree measuring worm, strawberry leaf-roller and crown 

 borer; apiculture, and dairying.
