CONNECTICUT. 113 



The cheese investigations were continued, special attention being 

 given to troubles encountered in the manufacture of Roquefort cheese. 

 In a study of the specific action of salt on the organisms in Roque- 

 fort cheese it was found tliat it does not inhibit the growth of Peni- 

 cillium but does check the growth of O'idiimi lactis. The work of 

 breeding beans and melons for disease resistance was pursued as pre- 

 vipusl}^ outlined. "With beans certain color correlations in stems, 

 flowers, etc., have been established in this connection. The relation 

 of lactic-acid bacteria to cheese making and the bacteriology of incu- 

 bating eggs were given further attention, and tlie part played by 

 micro-organisms in silage fermentation was studied. Biological soil 

 studies were also taken up during the year. 



Amonff the lines of work carried on with the Hatch and other funds 

 were farm management experiments, feeding experiments with cows 

 for milk production, feeding of high and low protein rations for 

 cows, ice-cream studies to determine the nature of the overrun, test- 

 ing cream for age, acidity, etc., as influencing the quality of ice cream, 

 supervising the testing of cows for advanced registry (at the ex- 

 pense of owners), studying the lime factor of soils, culture experi- 

 ments with corn, introduction of alfalfa, and determining the effi- 

 ciency of lime-sulphur spray on potatoes. The chicken-breeding ex- 

 periment for the production of a breed of hens having superior size 

 and vigor and which lay white eggs was continued, and an experi- 

 ment on the cost of feeding heifers in the college herd from birth to 

 2 years old was completed. 



The cooperative work of the station is limited to the cheese in- 

 vestigations, which are carried on with the Dairy Division of the 

 Bureau of Animal Industry. The extension and demonstration w^ork 

 is largely confined to orchard management and is done by the college, 

 station men as a rule giving little time to this feature. 



The following publications were received from this station during 

 the year: Bulletins 56, Control of Insects and of Plant Diseases; 57, 

 A Study of Some Connecticut Dairy Herds; 58, Camembert Cheese 

 Problems in the United States; 59, Bacterium lactis acidi and its 

 Sources; 60, Bacillary White Diarrhea of Young Chicks; 61, Apple
