Boston, Mass., August, 1913. 



In response to the above notice, 37 eligible contestants 

 entered the clean milk contest in the eastern section, and 

 114 in the western section. Eighteen contestants entered 

 the protection from flies contest. 



In the clean milk contest an agent was sent to each 

 farm who obtained from the owner replies to a list of ques- 

 tions with which he was provided, and who took photo- 

 graphs, both interior and exterior, of the stables, etc. The 

 milk of five cows, drawn in the presence of the agent, was 

 thoroughly mixed by means of stirring with a long-handled 

 dipper, after which one pint of milk was dipped out and 

 run through a sediment tester. The absorbent cotton in 

 the bottom of this tester was then removed and attached 

 to a small piece of round filter paper and placed in a box 

 which contained a number. This box was then sealed. 

 The agent, provided w4th a card bearing the contestant's 

 name, then wrote the number of the box upon the card 

 and sealed the same in an envelope. Both box and card 

 were afterwards turned over to the general agent of the 

 Dairy Bureau in whose possession they remained sealed 

 until handed to the judge. Prof. Samuel C. Prescott of 

 Massachusetts Institute of Technology, who placed the 

 entire 37 contestants in the eastern section, and the first 

 50 in the western section, in their proper order. After 

 the prizes had been awarded the envelopes were opened 

 and it was then ascertained who had won them. It should 

 be here stated that nearly all the cottons showed well for 

 unstrained milk, and the only reason why some failed was 

 not because of very dirty cottons but simply because some 

 one else had a slightly cleaner one. In many cases a magni- 

 fying glass was necessary to determine the difference. 



A brief description of the methods of the several success- 

 ful contestants is as follows : —
