STATE BOARD OF AGRICUUTURE. 



TABLE NO. I. 



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 plants 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 Plants No. 5 and No. 3. 

 These were tested for keeping quality 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 on a moderate day as to 

 temperature and the scores are better than they would probably have been 

 upon a hot day. A score of 100 is excellent and any samples scoring under 70 

 are very bad. Any samples scoring under 70 during weather as mild as when 

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