such a shortage they can sell it for double the price that was paid 

 the farmer. 



About the sanitary conditions, that is a point that I always 

 like to bring up and talk about especially. Mr. Newman gave 

 you a talk as to how to take care of your separator, but I want 

 to emphasize that point a little more. The separator ought to be 

 washed every time it is used, and I will give you one more point 

 in addition to what Mr. Newman said to make clear the neces- 

 sity of washing your separator every time. 



Everyone knows that in milking it is absolutely impossible to 

 produce strictly clean milk. We are not clean enough about the 

 milking but what we get some dirt into the milk. Every one 

 knows that who has ever used a separator and most of that dirt 

 stays in the separator. If that is left in over night, and there is 

 always some water in the separator, it is an ideal place for bac- 

 teria to grow. There are two kinds of dirt that always get into 

 milk, the soluble and the insoluble. The insoluble dirt is the kind 

 you wash, clean and then strain it out. The soluble is by far 

 the worst kind of dirt and the kind that cannot be detected by 

 the naked eye. The soluble dirt cannot be strained out. If it has 

 not dissolved in the milk before it got in the separator it will be 

 left there if the separator stands ove 1 : night without being washed. 

 Dirt carries bacteria, bacteria is the cause of so many poor flav- 

 ors; if you get dirt you get bacteria. If you leave that separat- 

 or standing all night with those millions of bacteria they are going 

 to grow. 



Whenever you run milk into an unwashed separator that 

 has been standing over night, the first part of the milk going 

 through is bound to carry millions and millions of bacteria; they 

 have had a chance to develop and produce anything that is bad. 

 A man with experience, as I have had, can tell on cream that is 

 delivered to the creamery pretty nearly what has happened to 

 that cream. I can tell you whether it is due to a dirty separator 

 or whether it is due to the place where you have kept it. There is 

 a difference in the flavor. I have investigated so many cases I 

 can tell in the smell and taste of cream what has ben the cause 

 of the bad flavor.
