COW has given during the month. It also enables one to 

 tell at once whether a cow gives less than her usual flow of 

 milk. If a cow has been giving fifteen pounds of milk, and 

 suddenly drops to thirteen pounds, one's attention is called 

 to the fact at once and the cause can be sought. It may be 

 found that the cow got out of the yard and that the dog 



was set on her; that she 

 was left out in the cold 

 too long; that she was 

 turned out to drink when 

 the wind was so cold and 

 the water so nearly froz- 

 en, that she did not get 

 the amount of water she 

 needed, or that a win- 

 dow or door was left 

 open and the cold 

 draught chilled her. 

 Whatever the cause of 

 the loss in milk may be, 

 if attention is called to 

 it, the cause and the 

 remedy may both be 

 found. 



Sampling. — A sample 

 to be tested for the per 

 cent of fat should be tak- 

 en just as the milk is 

 being weighed. Stir the 

 milk in the pail to make 

 sure that it is all uniform; 

 then take a small sample in a bottle. Each sample may be 

 tested soon after being taken, or a simpler way is to take sev- 

 eral samples from the same cow and keep them in one bottle, 

 and test all together. In this way of testing, some pre- 

 servative must be added to keep the samples from spoiling. 

 Testing. — Any careful boy, twelve or more years old, 

 can test milk, if he has a tester and is shown how, or, if the 

 milk is weighed at home and samples taken, the creamery 

 man will, as a rule, test them for a very small charge or for
