RECEIVING MILK OR CREAM. 15 



Some creamerymen test each sample soon after the 

 samples are brought to the factory and this system 

 is to be recommended. While the method of mak- 

 ing a composite test every week or two may give 

 good results in the hands of an expert, still there 

 are greater chances for errors than when cream is 

 tested at each delivery. 



11. Where cream is shipped by rail and the test- 

 ing is done at the receiving station the cream buyer 

 frequently takes a duplicate sample, places it in 

 a screw-top jar and drops the jar into the can of 

 cream. The cream is then shipped to the central 

 station and upon its arrival there the cream is care- 

 fully poured into a strainer. The sample jars are 

 then taken from the strainer, sent to the testing de- 

 partment where they are tested and the results ob- 

 tained compared with the tests made at the receiv- 

 ing station. While this method may be a very satis- 

 factory one from the standpoint of accuracy, yet 

 considering it from the sanitary point of view, it 

 is not to be recommended. The samples of cream 

 should be sent by express and not put in the cream 

 can. 



12. Testing each patron's cream while he waits. 

 In many cases where cream is delivered at the fac- 

 tory by the patrons themselves, it is tested while 

 they wait. The cream can is washed and a check 

 for the value of the cream is given to the patron. 

 This method is employed in many factories in Min- 

 nesota and Iowa. In Wisconsin and Michigan the 

 system is not so prevalent. Where the system of 

 testing at each delivery of cream can be employed
