fice of the petcock is caught. The relatively small amount of 

 milk caught in the pail is very readily mixed and the gill tak- 

 en. This method is not only theoretically accurate but has 

 proved to be practically correct in thousand's of trials; and it 

 has been found to obviate a large part of the errors and an- 

 noyances of sampling. 



Question — Do you have a drip near the outlet of the weigh 

 can? 



Answer — The drip should be located within a few inches of 

 the outlet of the weigh can. 



Gov. Hoard. I believe the first device of that kind used 

 was placed in our creamery and is yet in vogue. A hole was 

 punched in the bottom of the conductor running from the 

 weigh can to the vat at a point near the vat. The milk when 

 turned into the weigh can is a good deal mixed, the gate is 

 then lifted and it pours out in a rush and mixes itself running 

 and tumbling over and over, and just as it nears the vat, a 

 drop from every pound of milk falls into the jar. We get the 

 drip as far from the weigh can as possible. 



Prof. Hills. The fine wire-mesh strainer distributing 

 the milk into a thousand streams serves to quite an extent to 

 mix it. I do not advocate the automatic device unless the 

 fine wire-mesh be used. This device has been tried over and 

 over again as against extreme care in sampling, and has 

 proved, I think, correct in every case. It may be misman- 

 aged but it more surely takes an accurate sample than any 

 other practicable method since the sample in part takes itself, 

 regardless of care or lack of care on the operative's part. 



APPARATUS. 



A law was passed at the last session of the Vermont leg- 

 islature which required, among other things, that the Bab- 

 cock test apparatus used in dividend-making be accurate. 

 I have on this table six bottles. Three are good and three 

 bad. Can you tell me which is which? The manufac- 

 turer "guarantied" that all were accurate; yet notwithstand- 

 ing this guaranty some were excessively inaccurate. Here is an 

 accurate cream bottle. How do we know it is so? Not because 

 the manufacturer says so, but because, in accordance with the 

 state law, the experiment station has found out whether it is 

 accurately graduated or not, and certified thereto, if correct, by 

 grinding indelibly upon the neck of the bottle VtExSt. 



One creamery insisted that we send back all the bottles we 

 found to be incorrect. We did so. I doubt whether they were 

 used, however, afterwards; for we ground indelibly upon six 

 places on each bottle the word BAD.
