SUMMARY. 
1. Tuberculosis is one of the most important diseases of cattle. 
2. The Bang method of handling herds affected with this disease 
has been tried with success in various countries. This method is 
especially adapted to herds of valuable animals. 
3. The method consists in isolating the reacting animals in order 
to stop the spread of the disease and holding them for breeding 
purposes. 
4. Calves of tuberculous cows are rarely if ever tuberculous at 
birth. They should be immediately separated from the dam and 
fed on the milk of healthy cows or on milk which has been properly 
pasteurized. 
5. The milk of tuberculous cows is safe after it has been pas- 
teurized at 185° F. (85° C.). 
6. More than one-half of the herd of the New York Agricultural 
Experiment Station was found to be tuberculous in December, Igoo. 
7. Quarters were prepared and the application of the Bang 
method begun in October, 1901, with a total of thirty animals, thir- 
teen of which were healthy and seventeen tuberculous. 
8. During four years this herd produced twenty-three desirable 
heifer calves, approximately one-half coming from the tuberculous 
animals, and in November, 1995, it contained thirty healthy animals.
