o Herds at public institutions. 



The tuberculin testing of cattle in Virginia and Maryland, which 

 was started in 1907 in cooperation with the health department of the 

 District of Columbia with a view to obtaining a healthful milk sup- 

 ply foi the city of AVashington. was continued throughout the past 

 fiscal year. The requests from owners, especially in Virginia, for the 

 application of tuberculin tests to their herds, having spread beyond 

 those herds supplying milk to the District of Columbia, it was de- 

 cided to extend the Bureau's cooperation into other parts of Virginia, 

 "working with the office of the dairy and food commissioner of that 

 State and in accordance with the act of the state as.sembly passed in 

 March, 1910. The owners have been required, in accordance with the 

 custom of the Bureau, since the inauguration of the work, to sign 

 an agreement with the Bureau for the testing of their cattle, and 

 providing for the proper disposal of reacting animals, the disinfec- 

 tion of premises, and the protection of their herds from the entry 

 of untested stock. The results of tuberculin tests applied to cattle 

 in the States of Virginia and Maryland are shown by the following 

 table:
