Xorember. The lower feed cost for November was accentuated 
because the credit for manure and bedding was divided evenly 
among the 6 winter months regardless of the amount of feed con- 
sumed in the different months. 
The human labor performed each month, especially when expressed 
on the ''per cow" basis, was fairly constant within each seasonal 
period. The labor required to produce 100 pounds of milk fluctuated 
a little more, due to the variation in the amount of milk produced. 
It required 0.4 of an hour more human labor to produce 100 pounds 
of milk in the winter of the first year than in the summer, as com- 
pared with a difference of 0.3 of an hour for the second year. Atten- 
tion is directed to the fact that there was little variation in the 
average monthly labor required to produce 100 pounds of milk or 
to keep a cow in corresponding seasons of both years.
