pouring it from one pail to another, or by means of a dipper, and a test 

 sample is immediately taken. The Supervisor takes charge of and is 

 personally responsible for this sample, which is kept under lock and key 

 until tested. 



The test is proceeded with as soon as convenient after the milk has 

 cooled to ordinary room temperature. 



6 Duplicate fat determinations are always made by the Babcock 

 test and both determinations recorded. Readings of the results are made 

 at about 130 F., the test bottles are preferably placed in a small tin pail 

 containing water of this temperature for five minutes before the readings 

 are taken. If duplicates vary more than two-tenths of one per cent, the 

 test must be repeated. The sample taken of any one milk is not thrown 

 away until a satisfactory test of the milk is obtained. The Supervisor 

 shall enter at once the results obtained on his record book, and shall fill 

 out proper blanks, in ink or indelible pencil, on completion of test. 



7 If any of the milk or the test sample from a milking is accidentally 

 lost, the missing weight or the test credited to this milking is to be ob- 

 tained by taking the average of the corresponding milking during the test; 

 e. g., if the evening milking is lost or the sample therefrom, the average 

 of the weights or tests of the evening milking during the test is taken as 

 the yield or the test for the one lost. It must be stated on the report 

 that the data so obtained are estimated and not actual. 



8 The Supervisor shall be required to pay special attention to the 

 filling out of the test report blanks, especially as to dates of calving, ser- 

 vice, in heat, or not served, etc. Any sickness or other conditions shall be 

 made note of. A full statement as to feed shall be given. 



9 The Supervisor is not at liberty to decide as to which stipulations 

 contained herein are essential and which are not, but is required to ob- 

 serve these directions in all details. He shall report promptly any irreg- 

 ularity or unusual occurrence in connection with the test which he may 

 observe, and shall, in general, take all means to conduct a fair and equit- 

 able test of the cows placed under his supervision.
