Mr. Anderson : With 320 iiatrous you would save enough to pay 

 for him. 



Mr. Capper: We have 350 patrons and this summer we have 

 been doing daily testing, besides taking care of fifty hogs. 



Member: You said you didn't think very many were testing 

 every day. Isn't the majority doing daily testing? 



Mr. Anderson : I am afraid not. One thing in favor of daily 

 testing is the fact that the buttermaker knows every day how 

 much overrun he is getting. 



Member: It seems to me that these gentlemen are going off to 

 one side. The only point I see in daily testing is in giving every 

 man just what is coming to him. I don't think it makes any differ- 

 ence in the price you can pay. 



Member: Ask any of your patrons whether he would rather his 

 cream would be tested while it is sweet and clean or at the end of 

 fifteen days when it was sour and dirty. If you test once or twice 

 a month your sample is liable to mould on you. 



Mr. Thomas : We have a creamery with 280 patrons and we test 

 only once a month, but we never have any mouldy samples. We 

 used to have but not any more. I believe you can take samples 

 from day to day and keep them in perfect condition. The question 

 is, are you getting fair samples? I believe that is the greatest 

 drawback. The extra expense would amount to $40 per month 

 if we tested every day. If you sterilize your bottles you won't 

 have any trouble with mould. 



Mr. Trimble: How do you know what your overrun is? 



Mr. Thomas: We take samples two or three times a week from 

 the vat and find it in that way. 



Mr. Odell: Experiments in daily and composite testing have 

 been made at the colleges and there is a variation of between 1 

 and 2 per cent if taken every fifteen days and nearly 3 per cent 

 when taken every thirty days. Now if you have such a wide 

 variation as this how are you going to get j'our overrun? I was 

 talking to a buttei-maker the other day who said he had been test- 

 ing every day but had to go back to the composite method because 

 he couldn't do the work. I asked him how his overrun was when 

 testing daily. He said all right. I asked him how it was when 

 taking composite samples. He said he made it all right. Unless 

 you use glass-stoppered jars and take a proportionate sample the
