MILKING RECORDS. | 185 
This table presents several points of interest: Four milkers 
increased the milk flow 7, 10, ro, and 5 per cent. respectively, 
and the butter-fat yield was increased 1.1, 4.6, 12.6, 10.3, and 
8.8 per cent. These milkers were familiar with Dr. J. Hen- 
gerveld’s theory of manipulation of udder after the ordinary 
flow has ceased. ‘This is the probable explanation of the in- 
creased production over the 3-day period preceding the contest. 
The rate of milking may appear to be slow, but each milker 
dressed for milking, brushed his cows before milking, washed 
his hands, dampened the flank and udder of the cow, rejected 
the fore milk, milked the cow in a covered pail, weighed, sam- 
pled, and secured the yield in. the time given. 
The germ content of the milk drawn by the regular milkers 
during the same time is satisfactorily low, but the contestants 
in each case secured a lower germ content. ‘The samples from 
the milk drawn by the regular milkers showed an average of 
2846 germs per cubic centimeter, and the average of the sam- 
ples from the milk drawn by the contestants was 914 per cubic 
centimeter. 
The following score card we have used in judging the effi- 
ciency of students in milking. |
