(c) Milk, Cream and Feeds for Free Examination. 

 Five hundred and sixteen samples of milk, 1,315 samples of 

 cream, 1 sample of ice cream, 229 samples of feeding stuffs, and 

 3 samples of vinegar were analyzed. It is preferred that appli- 

 cation be made before such samples are sent in order that in- 

 structions for sampling and directions for shipping may be 

 sent. Duplicate inspectors' samples of milk will not be ex- 

 amined. While the chemical laboratory, in every way possible, 

 desires to be of use to residents of the State, its resources are 

 limited; hence, it reserves the right to refuse to make analyses 

 where samples are improperly drawn, where the work does not 

 appear to be of general interest or where it would apparently 

 serve no useful purpose. 



(d) Testing of Pure Bred Cows for Advanced Registry. 



Four men are given regular employment in conducting Jersey, 

 Guernsey, Ayrshire and Holstein yearly tests. These tests re- 

 quire the presence of a supervisor at each farm where cows are 

 under test for at least two days in each month. Two hundred 

 and fifty cows are now on test, at 37 different farms. Nine of 

 the cows are Holstein, 32 Ayrshire, 69 Jersey and 140 Guern- 

 sey. There have been completed during the year 5 Holstein, 

 45 Ayrshire, 148 Jersey and 178 Guernsey tests. 



The Holstein breeders usually test for seven or thirty day 

 periods, and require the presence of a supervisor during the 

 entire test, although there is also a provision for yearly work in 

 the Holstein-Friesian rules. During the year 22 different men 

 have been employed in these shorter tests and 166 seven-day, 

 36 thirty-day, 5 fourteen-day, and 2 sixty-day tests have been
