Before putting on the rafters and cornice, the siding is nailed on; it can be 

 done more conveniently before the rafters and roof boards are in place, there 

 being nothing to interfere with nailing on the boards under the cornice. 



Light 



The manner in which a barn is lighted is of importance. A dark barn is 

 bad in several ways. The most important objections are, that it is difficult to 

 keep clean, and is unhealthful. Make the barn sunny, for sunlight is Nature's 

 greatest disinfectant, and of material assistance in keeping the cows healthy. 

 There should be an abundance of windows. 



As a rule, four square feet of glass should be provided for each animal in 

 the barn. In cold climates, the windows should be a single sash of what is 

 known as double-glazed windows. Do not run windows crosswise. The 

 vertical window is far preferable. 



With a rectangular barn, it is well to have the long way north and south. 

 This will admit more direct sunlight to the stalls for the greater part of the 

 day. Windows placed in the north side of a barn are of little service, for they 

 admit no direct sunlight, which is necessary to destroy bacteria. South windows 

 are always excellent, but, unless numerous, do not admit so much light to 

 all parts of the barn as when placed on both east and west sides. 



The position of windows is a matter of importance. Buildings with thick 

 walls require larger windows to admit the same amount of light. It is best to 

 place windows the long way up and down, for they will admit more light than 

 when placed horizontally. They should be flush on the inside, to prevent 

 accumulation of dust. 



A single-sash window hung at the bottom is more practical than the double- 

 sash, as the single-sash window can be dropped at the top, and the air as it 

 enters is forced to the ceiling, thereby preventing drafts.
