No. 7. DEPARTMENT OF AGRICULTURE. 329 



SO that no germ can enter into tlie milk in that way. There are 

 many other ways of contaminating the milk — through th-e udder of 

 ithe animal, through the faeces, through the milker, through the 

 cooler, and even the air in which it is cooled. I would always have 

 the location of the milking house on the northwest side of the 

 building, because the prevailing winds are northwest, and they 

 carry the greatest amount of dust, so that there are more days 

 on which we can hav-e a freer, purer air on the northwest side of 

 tihe building.
