122 GUIDE TO DAIRYING IN SOUTH AFRICA 



3. Changes in the richness of milk, either from 



morning or evening milkings, and more 

 especially through indifferent milking. 



4. Separator running badly through using in- 



ferior oil, or bowl vibrating through being 

 out of balance. 



5. Amount of skim milk or water used for flush- 



ing the bowl, which often varies from day 

 to day. 



6. By removing the milk float, and overfeeding 



the machine beyond its capacity. 



7. By using the cheap and inferior variety of 



separator. 



8. Neglect to alter cream regulating screw in 



spring-time when milk is poor, and in 

 autumn when milk is richer. 

 These, then, are some of the principal reasons 

 why cream tests will from time to time vary, and 

 they have been discussed at some length with the 

 object of assisting the cream supplier to obviate as 

 much as possible these fluctuations, as by so doing 

 he will not only be assisting himself, but also our 

 creamery managers.
