88 DAIRY FARMING 



in the middle of the barn. In the first place it is more 

 sanitary. Where the two rows of cows face each other 

 the foul breath from each must necessarily pass from one 

 side to the other, thus causing the cows to breathe more 

 or less impure air. When the cows face out the exhaled 

 air is more equally distributed through the barn and in 

 so far reduces the amount of impurities in it immediately 

 in front of the cows. Another advantage in facing cows 

 out is the fact that the head is placed nearest the wall 

 where the temperature is lowest, leaving the portion of 

 the animal that must be most protected from the cold in 

 the warmer part of the stable. 



The silo is placed where it is most convenient for feed- 

 ing. Fresh air inlets are built in the wall of the barn 

 and two main air outlets are placed in the two box stalls, 

 with a third at the ceiling in the middle of the barn. The 

 driveway is such as to permit a team and wagon to 

 enter one end of the barn and pass out at the other. 



Founda'tion and Floor. The barn should rest upon a 

 substantial foundation constructed of stone or concrete. 

 On the outside of the foundation and a little below it 

 should be placed tile drains to prevent any water from 

 working its way under the foundation. 



For sanitary reasons, only concrete floors should be 

 permitted in a dairy barn. While the original cost may 

 be somewhat high, in the long run they are cheapest. 

 Aside from being easily cleaned, they also make possible 

 the saving of all the liquid manure, an important item to 

 consider in the management of a dairy. To prevent the 

 dampness commonly associated with a concrete floor it 

 should be constructed on a cobble stone and cinder foun- 

 dation underlaid with drain tile. The finish of the floor 

 should be rather rough to prevent cows slipping on it.
