COMPARATIVE STUDIES WITH COVERED MILK PAILS 103 
SUMMARY, 
The experiments given on the preceding pages seem to 
warrant the following conclusions: 
1. The use of the covered milk pail is of great advantage 
in any stable in excluding dirt and bacteria from the milk. 
The relative advantage gained by the use of the cover de- 
pends upon the sanitary condition of the stable. 
2. The special form of cover does not seem to be import- 
ant provided it is a device practical for use and the area 
through which dirt can gain access to the milk is reduced as 
much as possible. : : 
3. Whether or not a strainer on the covered pail is desir- 
able depends upon the style of the straining device. 
4. The use of the strainer in a pail where the dirt which 
falls into the opening is likely to be driven through by the 
succeeding streams of milk is not desirable. Its use tends 
to increase the germ content of the milk and injure its keep- | 
ing quality. 
5. In pails where the dirt which falls in does not remain 
where the succeeding streams strike against it a strainer cloth 
aids in keeping down the number of bacteria which gain ac- 
cess to the milk. The North pail is an illustration of this 
type. 
oA The use of absorbent cotton as a strainer as in the 
-Gurler pail is a decided advantage in preventing the entrance 
of bacteria into the milk. rh
