characteristics of the cow, such as her udder content, nervousness and 

 other peculiarities. This was balanced as fully as possible by milkin,!;- 

 a given cow into a protected and an unprotected pail on alternate 

 days. 



The germ content of the milk from each cow at each milking as 

 determined under these conditions is given in Table VI. 



Table VI. — -Effect of Protecting Pail on Germ Content of Milk. 



As will be seen from the above table the average germ content of 

 the milk in pails which had been protected with a cloth was 922 per cc. 

 while in the unprotected pails the average germ content was 2,391 

 per cc. This increase of 160 per ct. in the germ content due to the 

 exposure of the pails is at least a rough indication of the need, in 

 careful dairies, of protecting the pails after they have been satisfac-
