which vary with the conditions. The interest in the station grows 

 with the efficiency with which these questions are solved and the 

 adaptability of the solutions to actual practice.

At the last session the legislature appropriated about $1-22,000 

 for the maintenance of the station. No marked changes in funds, 

 buildings, staff, or equipment occurred during the fiscal year ended 

 June 30, 1910. 



AYork on both of the Adams-fund projects noted in the last report 

 was continued along the prescribed lines. The study of the func- 

 tion and importance of phytin in animal nutrition was conducted 

 under the project relating to the metabolism and physiological effect 

 of certain ash compounds fed to animals. Goats were used for these 

 experiments. In connection with this study calcium, potassium, 

 and magnesium compounds of phytin were made for use in the 

 investigation. Several series of results have already been obtained 

 with these salts Avhen fed to goats. Satisfactoiy progress was also 

 made in the bacteriological and chemical studies of cheese ripening 

 which were conducted cooperatively between the departments of 

 bacteriology and chemistry. This investigation included a study 

 of casein and i^aracasein, as well as bacteriological studies on the 

 changes of milk. The effect of bacteria on the products of para- 

 casein was also investigated. 



The greater portion of the station's work was maintained by State 

 funds. The chemical department continued work on milk and cheese, 

 principally on sour milk, koumiss, the ash constituents of cheese, 

 etc.; tested methods of determining potash in fertilizers; investigated 

 the acidity of gluten feeds, and made a chemical study of lime and 

 sulphur preparations, and of fermentation changes of citrates in 

 milk. A method was worked out for preparing a lime-sulphur 

 mixture, utilizing sulphur and lime with the least waste of material 

 and with the production of a solution having a maximum content 

 of calcium pentasulphid. 



The entomological department conducted studies of apple and pear 

 tree hoppers, cabbage maggots, tree crickets, ermine moths, and 

 maple-gall mites, together with tests of control methods. Spraying 

 with kerosene emulsion early in May, folloAved in about two weeks 

 with a second application, was found an efficient method of con- 

 trolling the pear psylla. Tobacco preparations combined with some 

 standard fungicide were found quite efficient against the psylla
