A study of the above table shows a gradual extension of the 



work in the control and eradication of bovine tuberculosis. More 

 territory has been covered each year, an increasingly larger 

 number of animals subjected to the tuberculin test and a certain, 

 steady decrease in the percentage of tuberculous animals in the 

 dairy herds accomplished. 



The figures and resulting percentages in the above table dififer 

 somewhat from those as given in the last biennial report because 

 of the fact that in this computation the calendar year was used 

 as a basis instead of the various tests designated as Nos. 1, 2 

 and 3. The difference, however, is slight. 



A study of the work accomplished in 1912 will give an adequate 

 conception di what is to be done in this direction this year on the 

 fourth general test of the dairy herds of the city and county. In 

 1912, 107 dairies were visited, of which number 60 may be con- 

 sidered city dairies, 15 private dairies and Z2 county dairies. A 

 total of 5290 animals were subjected to the intradermal tuberculin 

 test, of which number 5087 were passed and 203 condemned. 



Of all the animals condemned during the years 1910, 1911 and 

 1912, a total of 892, we can conscientiously say that not one 

 remains alive. The dairy herds are entirely free of condemned 

 cattle and not a drop of milk reaches the consumer from cows 

 known to be tuberculous. In the accomplishn^nt of these great 

 results we have been aided in every possible way by the dairy 

 owners themselves, which speaks volumes for our consistent cam- 

 paign of education. 



The sanitary condition of the dairies has advanced step by 

 step with the eradication of tuberculosis from the herds, and 

 while there is still room for improvement, sanitation has advanced 

 one hundred per cent, over and above conditions in 1910. The 



^Principally range cattle.
