of the barn. A sliding door next the gutter keeps the odors of the barn 

 from the milk room to which access from outside the barn is gained by 

 another sliding door four feet wide on the north end of the barn. 



Two box stalls for calves and incoming cows are adjacent to the milk 

 room and extend from gutter to feeding alley. They are each 10 feet by 

 8 feet. 



Across the central driving floor from the milk room, in the northeast 

 corner of the barn is a granary, 8x16 feet, extending from the gutter to 

 the east wall of the barn and therefore occupying that entire corner. 



In the middle of the barn north and south two stalls on each side are 

 left vacant and the partition removed to make a connecting alleyway 

 between the feeding alley on each side and the central driveway. 



The frame of the barn consists of a row of upright two by sixes, sixteen 

 feet long, standing on the 2x8 sills. These upright two sixes stand two 

 feet apart and against them on the outside the matched siding is nailed. 



In the west side of the barn there are ten windows, one every seven 

 feet, in the east side but nine, there being no window in the granary. The 

 distance from the main floor to the bottom of the supports to floor of the 

 mow over the cattle is 9 feet. These upper 2x10 floor joists are spiked to 

 the upright two by sixes of the frame at one end and rest upon a beam 

 supported by the row of posts standing between the cows at the edge ot 

 the gutter, at the other. This beam is made by spiking together three two 

 by sixes side by side. 



The rafters are spliced two by sixes supported by proper purlin plates 

 which in turn rest upon short posts resting on a cross beam on the floor 

 of the mow, which beam is vertically above the beam supported by the 

 row of posts between the cows on the edge of the gutter. 



The roof is of steel. 



The cost of the barn, exclusive of painting, was as follows: 



Foundation, stone and labor . - -. .. $41.22 



Lumber and windows 426.24 



Carpenter work _ .. 101.00

A row of cows stands on each side of the center drive way and facing 

 away from it. Most of the cows are confined in what are called Bidwell 

 stalls, a style of cow stall patented by Porter Bidwell of McGregor, Iowa. 

 In this stall, as built in this barn, the cow is not tied but is kept in place 

 by a partition on each side high enough to prevent her attempting to 

 jump over it, by a fence in front also high enough to prevent any attempt 

 to escape in that direction, and finally by a chain or rope stretched across 

 behind just above the gambrel joints which prevents the cow from back- 

 ing out. The width of the stall is so adjusted to the size of the cow that 

 she does not attempt to turn around. Twenty of the stalls in the new 

 barn are three feet and two inches wide. To test the matter eight others 

 are made three feet and four inches wide, but three feet and two inches is 

 wide enough for even large Holstein or Shorthorn cows. The length of
