without too much inconveniencf^ it should be used. 

 It has been found that the most uniform results in 

 testing cream can be obtained by testing it when 

 fresh, without the addition of preservatives. The 

 longer a composite sample is held before testing, the 

 greater is the care required in its preparation for 

 testing. 



13. Care of composite cream samples. A good 

 preservative should always be used. The sample 

 jars should be well shaken daily by a rotary motion, 

 and also whenever a new sample of cream is added. 

 The cover must be well fitted to the jar and the 

 jars should be kept in a cool, well enclosed compart- 

 ment. The evaporation of moisture from badly kept 

 samples is quite great and a little evaporation of 

 moisture raises the test considerably above the 

 actual fat content in the cream. The loss sustained 

 in this way by the creameryman handling a large 

 amount of cream is enormous. No matter how well 

 managed a creamery may be in other respects, the 

 creameryman cannot stand the loss incurred in this 

 manner — at least not for any considerable length of 

 time. Unless the greatest care is exercised in the 

 handling of composite cream samples, composite 

 sampling should not be employed. Cream samples 

 should not be held longer than two weeks ; holding 

 them for only one week is better, but testing every 

 day is the best method.
