These dormers also serve the more important purpose of giving hght and 

 ventilation to the haymow. You know what it is to mow hay on a hot sum- 

 mer's day, and can readily appreciate the value of ventilation and light in 

 that part of the building. 



The ventilators can also be made to add to the appearance of the barn if 

 they are correctly designed, and they can be made to aid in the ventilation of 

 the mow, as well as of the stable. 



The Walls 



The average height of the stable ceiling should be from eight feet six 

 inches to nme feet, at the walk behind the cows. Of course, as the floor is 

 usually built, this means that the height will be about ten inches less at the 

 feed alley. 



A greater height than nine feet calls for more heat to keep the stable com- 

 fortable, and is of no advantage in other ways. 



As the dairy section extends from the warm south to the cold northwest, 

 the construction should be modified to meet conditions. 



In the south, a wall of one layer of siding, tongued and grooved, or 

 battened, is sufficient for warmth, while at the northern extreme, one or more 

 dead air spaces are needed. The barn must be planned according to the 

 climate. 



In the south, barns may be built without wooden sides, canvas curtains being 

 provided to keep out the little chill that is sometimes present. 



On the other hand, it is almost impossible to keep the stable on the Dakota 

 prairie sufficiently warm when a blizzard is blowing. 



When building a concrete basement, the door header should never be 

 placed lower than the mudsills. To do so might make it difficult to put in 

 a carrier outfit, excepting by breaking out the concrete so as to allow the track 

 to pass. 



Posts or Columns 



In the planning of the barn, one of the most serious considerations is the 

 arrangement of the posts or columns. These should always be located about 

 six inches in the clear back of the curb, in line with the stall partition; or else 

 just back of the partition. 



If a post is located in the stall frame, it interferes with the proper construc- 

 tion of the cement curb; if ahead of the stall frame it interferes with the 

 manger or the alley; if located other than in a line with the stall partition it 

 takes up room out of the stall.
