a few stalls for use in milking. This style is well adapted to 

 certified milk production, as each cow may be groomed before 

 milking. An objection to this type of barn is that the cows 

 cannot be fed individually. It saves time in feeding, how- 

 ever, and the cost of construction is low. 



The barn with stalls is the more common type. In com- 

 parison with the other system it may be said to be economical 

 of room and that it enables each cow to be fed her proper 

 ration. The cows are under better control, and it is easier to 

 save and handle the litter.

in construction. This type usually has a monitor roof, with 

 a row of windows on each side. A loft or storage floor sup- 

 plies economical space and enables the barn to be kept warm 

 more easily. In this case all light must come from side win- 

 dows. 



The Foundation. The foundation for a dairy barn should 

 extend below frost and should be on firm soil. The width of 

 footing may vary from 12 to 16 inches. An 8-inch founda- 

 tion wall of concrete or hard-burned brick is sufficiently 

 strong; a wall of rubble work should be wider. Sills should 

 be 12 to 15 inches above the floor.
