quarter was drawn into a separate pail, and was weighed and 
tested. The average of the thirty milkings shows that 42.3 
per cent. of the total yield of milk was secreted by the front 
udder, and 57.7 per cent. by the rear udder. The average 
quality of the milk from each quarter was the same. 
Table 58 shows the quality and yield of milk from each quar- 
ter for one milking each in a herd of fifteen cows. In this trial 
the front udder yielded 38.8 per cent., and the rear udder 61.2 
per cent. of the total yield. The quality of the milk from 
each quarter was again practically the same. 
The average of the two trials shows that the udder of the 
cow is not balanced, but that about two-fifths (40.6 per cent. ) 
of the milk is secreted in front, and three-fifths (59.4 per 
cent.) in the rear udder.

Development of udder and capacity for secretion. — A good 
udder should extend well forward and up behind and from 
side to side. The udder should be large, but not at the ex- 
pense of fatty or fleshy tissue. The capacity for secretion is
