34 MODERN BUTTER MAKING. 



quite widely used at present and when properly- 

 handled gives very good results. The fact that some 

 creamerymen have not the proper facilities for car- 

 ing for the composite samples, as well as the fact 

 that some competitors test every day, has led fo a 

 system in some creameries of testing the cream 

 every day as soon as it is received and sampled or 

 as soon as the sample case containing the samples 

 from a route has arrived at the factory. Testing 

 cream for fat content soon after it is received at the 

 factory and while it is still in a fresh condition, is 

 becoming quite common and is received with much 

 favor. 



10. Sampling Case and Tubes. A suitable and 

 convenient sample case holding a sufficient number 

 of test tubes of any suitable size, as advertised in 

 creamery supply catalogues, may be obtained. The 

 hauler takes this ease on the road and at the time 

 of weighing each patron's cream he takes a well 

 mixed sample with a small dipper or graduated 

 tube, which delivers an aliquot part of the cream, 

 and puts in into the sample tube, which is provided 

 with a tight fitting cork. The cover of the case is 

 so closely fitted that when the cover is closed the 

 corks in the tubes cannot come out. This insures 

 a safe delivery of the samples. On arriving at the 

 factory these samples arc placed in a tank of warm 

 water, if necessary, and when warmed and well 

 shaken they are poured into jars containing a pre- 

 servative. In this manner samples are added as 

 often as cream is gathered during a period of a 

 week, two weeks or a month, and is then tested.
