COOPERATIVE TUBERCULOSIS INVESTIGATIONS. 



Continued good results have been accomplished in the cooperative 

 work for the suppression of cattle tuberculosis. The cooperation has 

 been conducted with owners of cattle herds in various States, with 

 the dairy and food division of the State of Virginia, the Commission- 

 ers of the District of Columbia, and the Office of Indian Affairs of 

 the Department of the Interior, 



Progress has also been made in interesting owners of pure-bred 

 herds of cattle in maintaining their herds free from tuberculosis, and 

 a growing interest in this matter is being shown by the State live- 

 stock sanitary authorities and by the breed-record associations. 



The following statement shows the results of the activities in the 

 District of Columbia, Virginia, and Maryland :

ERADICATION OF DOURINE. 



During a portion of the year work for the eradication of dourine 

 of horses was conducted in Montana, Nebraska, North Dakota, South 

 Dakota, Wyoming, and on the Navajo Indian Eeservation in Arizona 

 and New Mexico. The special appropriation of $100,000 made by 

 Congress February 23, 1914, having become practically exhausted, 

 and it being necessary to use all available inspectors in the work of 

 eradicating foot-and-mouth disease, the dourine work was almost 

 entirely suspended in October. On March 4 a new appropriation 

 made resumption possible. Notwithstanding these conditions, good 

 progress has been made and the percentage of animals reacting to 

 the test has been lowered. The tests are reported under the head- 

 ing of the Pathological Division,
