By comparing the data in Table 5 it may be noted that when the 
<cows were kept in the open shed they consumed more feed and pro- 
duced slightly more milk. The slight increase in production did 
not, however, entirely offset the extra cost of the larger quantity 
of feed consumed. On the average the cows when in the closed 
barn produced milk at a feed cost of 1 cent less per 100 pounds than 
when kept in the open shed; fat likewise was produced 1 cent per 
pound more cheaply. 
It was observed, however, that one or two cows in each group 
were "boss cows" when kept in the open shed, and were inclined to 
intimidate the weaker and less aggressive animals, especially at 
feeding time. Cows Nos. 14 and 20 were timid individuals, and, 
unlike the large majority, produced decidedly less when in the open 
shed than when in the closed barn. No doubt this tendency of the
