82 STORRS AGRICULTURAL EXPERIMENT STATION 
The first part of this table marked “A” shows the germ 
content of the milk drawn into an ordinary open milk pail 
and in part “B” of the same table is given the germ content 
of milk drawn into the same pail with a Stadtmueller cover, 
a cut of which is shown in Fig. 27. | 

Fic. 27—Stadtmueller covered pail used in experiments given in 
Table 18. 
The milk in these experiments was obtained from two cows. 
At one milking Nellie was milked into the open pail and Sully — 
into the covered pail and at the next milking the order was 
reversed, Sully being milked into the open pail and Nellie 
into the covered one. By alternating in this way the differ- 
ence in the germ content of the udders of the two cows is 
equalized in the experiments. A series of samples taken in 
this way should show with some accuracy the value of using 
this form of covered pail in a barn of this kind. It will be 
seen by comparing the experiments for the same day under 
“A” and “B” that in every case except one the milk drawn
