ELEVENTH ANNUAL YEAR BOOK— PART VIII 423 



Member: I would like to ask if there is some means whereby 

 these composite samples will not vary. In my territory we had to 

 give it up. A good many patrons got wise and they would change 

 the screw in the separator about every time they skimmed. We 

 would get one delivery of 50 per cent weighing about 25 pounds. 

 The next would test 30 and would weigh 40 or 50 pounds. They 

 would give us a large amount of low-testing cream and a small 

 amount of high testing cream, and on account of it we would have 

 heavy losses. "We found we had to test every can and get the exact 

 test. If we could have taken the right size sample we could have 

 overcome that. 



Mr. Fowler: There is no question but what the proportionate 

 sample is the only correct way. 



Member: Can you keep track of every man's cream that way 1 ? 



Mr. Fowler: A proportionate sample is taken by the weight — 

 not by the amount of butterfat. 



Mr. Payne : I would like to ask if we would not be far better 

 off by testing every individual can instead of using the composite 

 sample. I find several reasons why it is better. One reason is, 

 as a general thing the farmer wants to know what his test is. If 

 you test each individual can you can let him know. That helps us 

 a great deal. I don't think it is the right way to instruct butter- 

 makers to take composite samples. When you test every can you 

 arc working along the lines that the centralizers follow, and it is 

 the only right way. Here is another thing in taking the sample. 

 I find it easier to use a small graduate to take the sample to weigh 

 instead of a pipette. 



Mr. 'Neil : I would like to say that composite testing does not 

 give the buttermaker a true check on his work from day to day. 

 By testing every can every day he knows exactly just how much 

 fat lie has. Some take a drip sample, but cream is sweet and sour, 

 thick and thin and the result is not accurate. Daily testing is 

 better for the buttermaker. better for the creamery and better for 

 the patron. 



Mr. Fowler: I stated when I started out that the only proper 

 method is to test every can, but conditions sometimes shape them- 

 selves so it is impossible for every buttermaker to do this, and I 

 happen to be one of them. 



Mr. Payne : How is a buttermaker to keep a daily record if he 

 uses a composite test?
