Beier ER-FAT vs. SPACE SYSTEM FOR PAYING FOR 
CREAM AT CREAMERIES. 
BY CHAS. D: WOODS. 

That the milk from different cows varies materially in its com- 
position has been long understood. It is, however, but a few 
years since advocates of a deep setting system for cream claimed 
that when it was raised under uniform conditions, a space of 
cream always contained the same amount of butter-fat. When 
this Station undertook, in 1890, a series of feeding experiments 
with milch cows, a Cooley creamer was purchased and the 
instructions as to temperature of milk at time of setting, temper- 
ature of water, etc., were carefully followed. Analyses of the 
cream speedily convinced us that the method was far too inaccu- 
rate to be relied upon as a measure of the butter-fat production 
of cows. The range of composition of the cream may be seen 
from the following tabulation of a few of the results obtained.

uniform conattions of temperature, etc. Leach analysts
