 made later, and especially to report every change in the

 actual observance of these requirements should be con- 

 trolled by frequent visits of a veterinarian appointed 

 by a central authority or by occasional visits of the 

 local veterinarian, but the latter plan is not so satisfac-

Such a regulation would, of course, be particularly 

 difficult in large cities as, for example, Copenhagen, 

 which receives milk not only from a very large number

 manded of producers and no special control has been 

 provided to enforce these regulations. The local boards 

 of health have the right to investigate cases which are 

 reported and if necessary to forbid the sale of milk from 

 the premises involved. 



[In the United States, there is a certain amount of 

 dairy farm inspection under the authority of the states. 

 In Massachusetts, herds are inspected by the Cattle Bu-

 the State Livestock Sanitary Board, on request from 

 local boards of health that their milk supplies be exam-

 Commissioner, the Commissioner of Agriculture or the 

 State Board of Health. In no state, however, is there a
