TABLE NO. II. 



The fact that one plant has a higher score than another does not necessarily 

 prove that the one plant is delivering a safer grade of milk, but it does show 

 that the one plant is better equipped to handle a safe product and is using 

 methods which are more dependable than are those of the plant with the 

 lower score. 



To get an idea of the condition of the milk as it arrived at the city milk plant 

 samples were taken upon arrival at Milk Plant No. 3 and at Milk Plant No. 1. 

 These were tested for keeping quaUty by the pH method which grades milk 

 according to the activity of the bacteria which are present rather than accord- 

 ing to the numbers. These samples were taken upon a rainy day following a 

 cold night and the samples are in much better condition than would have 

 been the case had samples been taken on a warm day foUowig a warm night. 

 A score of 100 by this test is excellent and any samples scoring under 70 are 

 very bad. Any sample scoring under 70 during weather as cold as when 

 these samples were taken would be very bad indeed if the weather was warm. 



The score of milk arriving at Milk Plant No. 3 follows: 



pH score. 



Dairy Farm No. 1 85 Dairy Farm No. 11 . 



Dairy Farm No. 2 95 Dairy Farm No. 12. 



Dairy Farm No. 3 55 Dairy Farm No. 13 . 



Dairy Farm No. 4 95 Dairy Farm No. 14. 



Dairy Farm No. 5 100 Dairy Farm No. 15. 



Dairy Farm No. 6 95 Dairy Farm No. 16. 



Dairy Farm No. 7 95 Dairy Farm No. 17. 



Dairy Farm No. 8 85 Dairy Farm No. 18.

The average pH score of 87 indicates that the milk as a whole arrived at 

 the plant in excellent condition in spite of the very poor milk arriving from 

 farms 3, 14 and 16. Attention should be given to these farms to locate the 

 trouble and suggest means for overcoming it. 



Enough samples were taken of milk arriving at Milk Plant No. 1 to get an 

 idea of the condition of the milk arriving at that plant. The score of these 

 samples follows :
