8o Department of Dairy Industry. ' 



cows, representing nineteen herds, were tested monthly throughout the 

 year. The value of this work to the dairymen may be judged by the fact 

 that at the beginning of the third year's work, May first, without any 

 soHcitation on the part of our department, the number of herds included 

 in the work has been increased to thirty-six with a total of 370 cows. 

 The results of the first two years' work are now being put in bulletin form 

 for publication. 



5. A study of the factors affecting the accuracy of the Babcock Test. — 

 Considerable work has been done by the different Experiment Station 

 workers on the best method for making the Babcock Test. There still 

 remain, however, a number of unsettled problems and much difference 

 of opinion regarding the accuracy of certain steps in making the test. 

 It is hoped that the work now under way will aid in settling some of these 

 questions. 



6. Camembert cheese. — The experimental work in the manufacture of 

 Camembert cheese has been continued. It will take some time to solve 

 some of the problems in connection with the making of this cheese, but 

 very satisfactory results have been obtained and the work will be con- 

 tinued during the coming year. 



EXTENSION. 



Extension work performed by this department may be considered 

 under the following heads : 



1. Correspondence. — Prompt attention to the letters of inquiry received 

 by the office is one of the important lines of extension work. The depart- 

 ment receives large numbers of letters from dairymen in all parts of 

 New York State, and other States as well, seeking information in various 

 lines of dairy work. An effort is made to furnish the desired information 

 just as far as possible. 



2. Addresses at farmers' institutes and other meetings. — The regular 

 teaching work of the department makes it difficult for members of our 

 staff to get away from Ithaca for any length of time. Members of the 

 department, however, during the year have given addresses at twenty-six 

 farmers' gatherings. In addition to this the department sent an exhibit 

 and one or more men on the special farm trains which were run through 

 the western and northern parts of the State. 



3. Exhibits at fairs. — The department has made exhibits at the follow- 

 ing county fairs : Whitney Point, DeRuyter, Boonville, Warsaw, Water- 

 town, Greene, Ogdensburg, Binghamton. 



At each of these fairs one or more members of the department staff 

 were in attendance. The department also had an exhibit in the State
