Io8 Barn Construction. 



If the cattle barn is to be under the main barn, as is 

 usually the case, or simply a shed, the method of 

 constructing walls with double air spaces is as fol- 

 lows: On the sill twelve inches wide, set up a two- 

 by-four one inch back from flush with the outer 

 edge. On this nail sheathing, on the sheathing 

 building paper, over the building paper clapboards 

 or novelty siding, or whatever siding is desired for 

 the outside of the barn. On the inside of the two- 

 by-four studding nail inch sheathing; over this 

 building paper; then set up another two-by-four 

 against the inside or middle lining, and on the other 

 edge nail sheathing, then building paper, and cover 

 with matched siding (see cuts). The idea is to get two 

 dead-air spaces. The nearer airtight the spaces are 

 the more perfectly the cold will be excluded in winter 

 or the heat kept out in summer. An airtight air 

 space is one of the best non-conductors of heat or 

 cold for barn, silo, or icehouse. It is far better than 

 to have the space filled with sawdust. Where lath 

 and plaster is more economical than sheathing and 

 building paper, it makes an equally good partition, 

 dividing the two air spaces. This method of build- 

 ing side walls is less expensive than stone or brick 

 masonry, and when finished is so much warmer in 

 winter, so much cooler in summer, so much drier, 

 cleaner, airier, and more wholesome, that there is no 

 comparison between the two. 



The windows should for the same reason be made 

 to accommodate three sashes both for winter and 

 summer. The windows, however, should be large
