130 PRINCIPLES AND PRACTICE OF MILK HYGIENE 



is to have the windows on the east and west sides with the 

 two rows of cows extending north and south. The win- 

 dows on the west side can be provided with wood shutters 

 to keep out the sun on hot summer afternoons. When 

 the shutters are up the flies will also be less troublesome 

 on that side of the stable. 



(d) Surroundings. The location of the manure 

 dump and the direction of the surface drainage from 

 the same should be observed, particularly with relation 

 to the location of the source of the water supply. The 

 accessibility of the manure pile to cows turned out for 

 exercise or being driven into or out of the stable should 

 also be considered. When cows are permitted to wander 

 about in a lot of manure they become very much soiled, 

 especially their legs and udders, and also carry a good 

 deal of dirt into the stable. 



The proximity of other buildings, especially if used 

 as horse stables, chicken houses, pigpens, etc., should be 

 noted. Buildings used for these purposes, as well as 

 manure piles, are breeding places for flies and are there- 

 fore objectionable when too close to a dairy stable or milk 

 house. 



Attention should be given to the condition of the 

 barnyard or exercise yard. Note its size and whether or 

 not it is well drained. The condition of the barnyard 

 has a considerable effect upon the cleanliness of the cows 

 and stable. If it is muddy or dirty, some of this material 

 will become attached to the cows and will be carried into 

 the stable, increasing the labor of cleaning the cows and 

 the stable. 



2. Interior of the Stable. In examining the cow stable, 

 the fact should be kept in mind that it is not only a shelter 

 for animals but is also a place where human food is pro-
