In order to secure sanitary market milk many 

 plans have been devised, some of which have been 

 put in operation in the different states. The 

 conscientious dairyman who honestly desires to 

 deliver sanitary milk to his patrons or to the city 

 dealer will naturally be interested in observing all 

 precautions which tend to the best preservation of 

 milk. To this end a large number of factors 

 contribute. In the first place, the stable should 

 be arranged with a view to the comfort of the 

 animal. Floors, gutters, walls and ceilings should 

 be constructed so that they can be readily cleaned. 

 Ventilation must be provided so that disagreeable 

 odors will be rapidly carried away. The stable 

 must be scrupulously cleaned at frequent inter- 

 vals and, if at all possible, the milking stable is 

 best separated from the feed barn for the reason 

 that dust from hay and odors from other feeds are 

 thus prevented from getting into the milk. The 

 herd itself must be tested with tuberculin and 

 known to be free from tuberculosis. All cows 

 must be healthy in every respect. Particularly, they 

 must be free from garget or any form of inflam- 

 mation of the udder which can influence the ap- 

 pearance or condition of the milk. While not all 

 animal diseases are transmitted to man, it is ob- 

 viously dangerous to human health to sell milk 

 from any cow suffering from a serious disease, es- 

 pecially if it is accompanied with high fever. 

 The water supply should be carefully guarded and 

 should not Be drawn from close proximity to 

 manure heaps, privies and other sources of con- 

 tamination. The milkers must be cleanly in all 

 their habits and of course be in health. It should 

 be strictly forbidden that any one affected with 

 a contagious disease, or living in the same room
