ERADICATION OF TUBERCULOSIS FROM AREAS. 



The eradication of tuberculosis from cattle within circumscribed 

 areas, with the county as the unit, has proved to be the most effec- 

 tive plan so far tried. Excellent progress was made. At the close 

 of the fiscal year one or more tests of all cattle in 81 counties had been 

 completed, being an increase of 50 counties during the year, and 117 

 additional counties were actively engaged in testing cattle. The 

 status of this work is shown by States in the following table :

■ Testing reported done under community or township plan. 

 ' Testing completed prior to fiscal year 1923. 



The greatest advances were made by the States of California, Idaho, 

 Illinois, Indiana, Michigan, Missouri, Montana, New York, North 

 Carolina, Oregon, Washington, and Wisconsin. In these States ma- 

 chinery seems well laid for a systematic continuation. Area testing 

 was begun in Arizona, Ohio, and Pennsylvania, while arrangements 

 were made through State laws and appropriations to expedite the 

 work in a number of States, including Iowa, Minnesota, and Illinois. 



Emphasis has been laid on the necessity of obtaining as much 

 assistance as possible from the counties. Such assistance has been 

 provided in a marked degree in Michigan, Illinois, and North Caro- 

 lina. In Michigan 36 counties have appropriated about $185,000,
