fairly good condition. Now, if it is not sour enough to clog the separator, 

 it is received at the weigh-can of many creameries. When every man 

 made his own butter on the farm and sold it himself, he came into closer 

 touch with the trade and was more particular about the cleanly methods 

 of its production. Since the creamery has come in between the milk pro- 

 ducer and the butter market there is a tendency to become more careless 

 in the production of milk. When milk is delivered in poor condition at a 

 creamery or cheese factory, no butter or cheese maker, however skilled, 

 can make the best product from it. If all of the patrons but one bring 

 milk that is clean and in good condition, the man bringing dirty milk spoils 

 the whole. 



The condensing factories have been the greatest factor in raising the 

 standards of milk production upon the dairy farms of the state. They 

 make certain requirements in regard to the methods used in the produc- 

 tion of milk delivered at their factories and have inspectors to see that 

 their instructions are carried out. 



The particular points touched upon in this bulletin are the ones found 

 to be most commonly at fault in actual practice. The object of this bulle- 

 tin is to show how these may be remedied and to point out the essentials 

 of good dairying. It must not be inferred, however, that the Experiment. 

 Station recommends expensive buildings and equipment in the production 

 of clean sanitary dairy products, for these are not essential. It costs little 

 more to be clean than unclean. It does, however, require a little more 

 labor. 



Location of Barn and Care of Yard. 



In the production of clean milk no one thing is of more importance 

 than keeping the cows out of the mud. Many yards into which dairy cows 

 are turned each day for their drink and exercise, are knee deep with mud 

 and manure during the winter and spring, if not nearly the entire year. 

 In summer when the cows are on pasture they would keep comparatively 

 clean were they not obliged to wade through a filthy yard in going to the 

 stable. 



In locating a dairy barn care should be taken to have a gentle slope 

 from the barn in at least one direction, affording a good natural drainage 

 for both barn and yard. If the barn is already built and poorly located,
