 during the fiscal year.

Under the supervision of bureau officers there were tested with

The District of Columbia gives an illustration of what may be 

 accomplished during a term of years by the systematic testing of 

 cattle for tuberculosis and properly disposing of reactors. Work of 

 this kind has been under way in the District for 10 years. At the be- 

 ginning of this period the tuberculin test showed that 19 per cent of 

 the cattle were tuberculous. During the past fiscal year 1,264 cattle 

 in the District were tested and only 8 reactors obtained, a percentage 

 of 0.63. Three hundred and seventy cattle in interstate movement 

 were also tested for admittance into the District of Columbia, and of 

 this number 30, or about 8 per cent, were found to be infected with 

 tuberculosis. 



INSPECTION AND TESTING FOR INTERSTATE MOVEMENT. 



During the year there were inspected by bureau veterinarians, in 

 compliance with the laws of the States to which the animals were 

 destined, 41,609 cattle moved interstate for purposes other than im- 

 mediate slaughter, of which 40,686 were tested with tuberculin. Of 

 the number tested 1,182 reacted.
