tered at various gatherings of farmers and thus there was 

 presented to them evidence of the ravages which the disease 

 may occasion in an apparently healthy animal. 



If progress was to be made, the tuberculin test must be 

 widely used. The limited number of veterinarians available 

 for the work made evident the necessity of extending its appli- 

 cation to the laity. With this idea in mind, special instruc- 

 tion in the use of the test was given to the students of the 

 agricultural college, both in the regular and in the short 

 course. 



It was suggested that the prevention of the sale of tuber- 

 cular animals would be the most effective way of stopping 

 the spread of the disease. The passage of a law was urged 

 that would require the testing of all cattle sold for breeding 

 and dairy purposes. Such a law was enacted. 



The first of these steps was opposed by the veterinarians 

 who felt that it was an encroachment on their field; the 

 second was opposed by the farmers who had not been or who 

 would not be convinced of the importance of the disease. The 

 plan was too early to meet with the approval of those most 

 concerned, and by the time they had become ready to give to 

 such a plan their sympathy and approval, it was too late for 

 such or any plan to have much effect. 



Looking backward from the vantage point of present knowl- 

 edge, one can see how great a factor the plan would have 

 been in preventing the spread of the disease which is rapidly 

 becoming the most important as far as the economic and sani- 

 tary aspects of the dairy are concerned. 



Dean Russell served as a member of the State Live Stock 

 Sanitary Board for a number of years. The work in bovine 

 tuberculosis led to an interest in human tuberculosis. The
