^•as purchased. In South Carolina the activities resulted in the 

 increased use of milk in 1,384 families and in the purchase of 73 

 family cows. Sixty demonstrations were given in buttermakinf? 

 and 38 in making other dairy products. The work in Mississippi 

 resulted in placing 322 family cows in 11 counties and in the pur- 

 chase of 2,U4() pieces of improved dairy equipment. Dairy clubs 

 were organized in 11 counties, 49 meetings were held, and 76 demon- 

 strations were given. 



DAIRY MANUFACTURING INVESTIGATIONS. 



CUKAJIEKY DliVKI.OPMENT AND I Ml'UOVKMKNT. 



Special efforts were directed toward increasing the efficiency of 

 creamer}' operation and improving the quality of manufactured 

 products. In the South, where the creamery business is compara- 

 tively new, help was given in the organization of local creameries, 

 in the selection and arrangement of equipment, and in increasing the 

 efficiency and econom}' of operation. 



With the higher prices of coal and wood has come new ap- 

 preciation of the work on fuel and power efficiencj^ and refrigeration, 

 which has been continued with creameries in Minnesota, Iowa, Wis- 

 consin, and South Dakota. Particular attention has been given to 

 the saving of fuel through the use of exhaust steam, hot-water heaters, 

 and as a result 27 heaters were installed. Electric motors were in- 

 stalled in several creameries on the recommendation of the Dairy 

 Division, as a means of obtaining more economical power. Assist- 

 ance, has also been given in the planning of refrigerator storage 

 rooms at a number of creameries. 



THK CJKOVK CITY CREAMERY. 



The cooperative creamery at Grove City, Pa., has continued in 

 successful operation under the direction of the Dairy Division. The 

 making and marketing of comparatively large quantities of cheese 

 of the Roquefort, Swiss, and Camembert varieties under connnercial 

 conditions have furnished an opportunity for study and improvement 

 of the manufacturing methods and have demonstrated that those 

 varieties of cheese, heretofore largely imported, can be profitably 

 made in this country. The products were of high quality. The year's 

 output of Swiss cheese was 112,000 pounds; of Roquefort, 12,378 

 pounds ; and of Camembert, 7,737 pounds. The butter made amounted 

 to 505,904 pounds, part of which was packed in sealed tins for ex- 

 port. Considerable attention has been given to the working out of a 

 satisfactory cost-accounting system. 



INSPECTION OF HUTTER FOR THE NAVY. 



During the last season 1,392,369 pounds of butter, made for the 

 Navy at 43 creameries, was ]iassed on by 29 inspectors of the Dairy 

 Division. The average score for all samples of the butter taken 

 at the time of manufacture was 95; the average score after storage 

 was 92.71. The specifications require that the butter be made from 

 sweet cream. The excellent kecjiing (lualities of this butter are
