It is a mistake to put windows in a barn with the long 

 dimensions horizontal. Up and down windows admit the 

 sunlight further into the barn. The dotted lines represent 

 the amount of sunlight cut out by the ordinary 18 inch stone 

 wall. 



The direction in which the barn stands has much to do 

 with the amount of direct sunlight that enters it. In Wis- 

 consin, if the barn stands east and west, direct sunlight 

 enters only through the south, east and west windows, and

If the long dimension of a Wisconsin barn is placed north and south the sun 

 shines on the two sides and one end; if placed east and west, on two ends and a side. 



only indirect sunlight on the north. A barn standing north 

 and south receives direct sunlight on both of the longest di- 

 mensions each day, or on the east and west, as well as on the 

 south side, and indirect on the north side. As far as possible, 

 buildings should be lighted from the south in the middle 

 northern latitudes, as the maximum amount of direct sun- 

 light may thus be obtained, by either an east and west or 

 north and south arrangement, provided windows are not 

 obstructed in either position. The barn should be placed 

 with long dimensions north and south if a bridge or bank is to 

 be built to the second floor. A barn standing north and south 

 is generally cooler in the summer time as the prevailing winds 

 from the south and southwest create a draft through the 

 barn. In the winter time there is very little difference as 

 far as temperature is concerned.
