The number of hours required to care for a cow does not differ 

 materially in summer and winter, but the number of hours required 

 to produce 100 pounds of milk shows a marked increase from Novem- 

 ber to March, inclusive. This season corresponds quite closely to 

 the months of intensive winter feeding, when the cows are kept in the 

 barns or yards during the nights ; it also corresponds to the months 

 in which the smallest volume of milk is produced, and this fact exerts 

 a great influence over the amount of labor required for producing 100 

 pounds of milk. This is more fully substantiated by the fact that 

 during the months of May, June, and July we find the lowest time 

 requirements for producing 100 pounds of milk because of the higher 

 percentage of milk produced per month. 



The small amount of horse labor was due to the use of motor trucks 

 for collecting the milk and hauling it to market. 



During the winter horses were used at some farms to haul the milk 

 from the milk house to the road. In summer they were used for driv- 

 ing cows to and from the pasture; however, during July, August, 

 and September, when the horses are hitched to the harvest wagon,
