SEVENTH ANNUAL YEAR BOOK— PART VII. 293 



or jar. In order to mix that so when you take the butter from it 

 you will not take butter with a big drop of moisture, or butter 

 with absolutely no moisture in it, set the bottle in water at about 

 100 degrees temperature and let it melt so it will be soft and 

 slushy, then shake that all up and thoroughly mix it in that way. 

 You will then have the water mixed all through the butter and 

 can have an accurate sample of the amount in your bottle. If 

 you take it from a tub there is a question that perhaps needs 

 more light than we have, but ordinarily I think one or two triers 

 run through the tub and then taken out the length of the trier 

 will give you an accurate sample. Care must be used in getting 

 a proper sample as in getting a proper sample of cream when 

 testing for your patrons. If you get a sample too rich in fat by 

 taking it off the top of your can, the test is worthless. Just the 

 same here, if the sample is not representative of your butter it is 

 worthless. 



Member: What assurance will we have that those bottles will 

 be manufactured accurately. 



Prof. Webster: The same assurance that we have that our 

 Babcoek tests are accurate. 



Mr. Wilcox : Should a sample stand long before it is tested. 



Prof. Webster : If it stands long have it covered so the mois- 

 ture will not evaporate. If you put your milk sample in a test 

 bottle and allow it to stand, when you test it the fat is all there. 

 If you put a sample of your butter in a little flask and go back 

 in two or three days most of your moisture is gone. You must 

 make the test at once or have tight, rubber stopper on your bottle 

 or something to close it up. 



Most of the samples we take in the department are of renovated 

 butter and of course these are not comparable with creamery butter. 

 We have taken few samples of creamery butter for analysis. 



Mr. Newman : I believe that most creameries are not getting 

 enough water in their butter. 



Prop. Webster : If they are doing that they are robbing them- 

 selves and their patrons, just the same as if they were doing any- 

 thing else. A man wants to keep low enough so as not to be be- 

 yond the limit of the law ; up to 15 per cent or 16 per cent of 

 moisture does not affect the quality of the butter, but when you 

 get it 20, 25 and 30 per cent, and I have tested as high as 35 per 

 cent you are going pretty high.
