36 a EXPERIMENT STATION. [Jan. 



(d) Other Work. 



In connection with the work required under the preceding 

 headings this department has continued to analyze samples 

 of milk, cream and feeds sent by residents of the State where 

 circumstances would appear to warrant the procedure. Work 

 is not done, however, which belongs more properly to a com- 

 mercial chemist. During the year 226 feeds, 543 milks, 430 

 creams, 1 condensed milk and 26 vinegars have been analj^zed. 

 One hundred and forty-five feeds and 163 samples of milk 

 have been analyzed in connection with feeding experiments 

 conducted by the experiment station. 



Seventy-three moisture tests on corn have also been made 

 for the purpose of determining yield on a uniform basis for 

 corn contests conducted by the State Department of Agricul- 

 ture and the Massachusetts Society for the Promotion of 

 Agriculture. 



An investigation was also conducted to determine the most 

 accurate method for determining butter fat in condensed milk 

 and ice cream. 



Work included under this heading supplements the work 

 required under the feed and dairy laws, and can be done at 

 such a time as to keep equipment and staff utilized during the 

 entire year. 



(e) Testing of Pure-bred Cows for Advanced Registry. 

 Four men have been given regular employment in conduct- 

 ing yearly tests of Jersey, Guernsey, Ayrshire and Shorthorn 

 cows, and, in addition, extra men are employed as occasion 

 demands. This work requires the presence of a supervisor 

 at a farm for at least two days each month. The two-day 

 test period forms a basis for computing the monthly milk 

 and fat yield reported by the breeders direct to their respective 

 cattle clubs. This work is done at cost, and the funds re- 

 ceived kept in separate account by the experiment station 

 treasurer. As the work must be self-supporting, breeders are 

 required to pay for tests before papers are forwarded to tfie 

 cattle clubs. Following is a monthly summary of the work 

 for the two-day yearly tests: —
