342 ANNUAL RKrORTS OF DEPARTMENT OF AGRICULTURE. 



come of the venture, of course, can not be determined at the end of 

 only Olio yonr's operation, hut there is f^ood c^round for belie¥in^ that 

 it will be prolitable linancially as well as hy^ienically. A <»;reat deal 

 of credit is due to Paymaster Bryan, whose untiring efforts have 

 overcome many dilFiculties in the way of the enterprise. The use- 

 fuliit'ss of this dairy will demonstrate, as is Ix^lievod, the desirability 

 of similar institutions generally maintaining their own dairies. 



DAIRY ENGINEERING. 



One of the features of the dairy engineering work during the fiscal 

 year has been a study of refrigeration, including compressors and 

 storage rooms. Lack of knowledge regarding the special require- 

 ments of refrigeration for dairy uses has caused, it is believed, many 

 inadequate installations. A circular has been prepared covering this 

 special field in refrigeration. Other studies have related to the most 

 economical use of fuel in creamery and milk plants, the cost of pas- 

 teurizing a flow of milk or cream, and a practical method of freezing 

 milk. 



In addition to the foregoing, a large number of plans for all kinds 

 of dairy buildings have been prepared and sent out for use in the 

 field. Special plans have been made for the Naval Academy dairy 

 and the Beltsville experimental farm. 



WESTERN INVESTIGATIONS. 



On account of the splendid opportunity for educational w'ork along 

 dairy lines in the Rocky Mountain and Pacific Coast States and on 

 account of the growing demand for the kinds of work which the 

 Dairy Division has been carrying on in that section for the past two 

 years, and also because of the great distance of that section from 

 Washington, plans have been made to organize a new section in the 

 division to handle the work in those regions, with headquarters in 

 Salt Lake City, Utah. Western investigations will include all work 

 done in the Rocky Mountains and the Pacific coast region, whether 

 in connection with creameries, market milk, or dairy farming, and 

 the man in charge will report directly to the chief of the division. 

 The organization for this work differs from that of the remainder of 

 the division in that this includes the whole dairy field, whereas the 

 other sections cover only certain branches. 



THE INSPECTION DIVISION. 



The work of the Inspection Division, consisting of the meat inspec- 

 tion and the control and eradication of contagious diseases of 

 animals, under the direction of Dr. R. P. Steddom, chief, was con- 

 tinued as previously up to the end of the fiscal year. Beginning 

 with the new fiscal year, this division has been reorganized as two 

 separate divisions, designated as the Meat Inspection Division and 

 the Field Inspection Division. 



THE MEAT INSPECTION. 



The meat-inspection work for the fiscal year 1912 shows an increase 

 along all lines, esj^ecially in the number of post-mortem inspections, 

 the amount of meat food products prepared, and the export ship-
