DISEASES OF CATTLE. 



exclusive use of southern cattle shall be similarly disinfected. "Where 

 these animals are yarded adjacent to cattle from above the line at 

 least a 10-foot space not occupied by cattle must be left between, on 

 the inside of which shall be a tight board fence not less than 6 feet 

 high, and on the outside a similar fence not less than 5 feet high. 

 The yards or portions of yards reserved for cattle of the quarantined 

 area shall be so located, or such drainage facilities shall be provided 

 therefor, that water therefrom will not flow on to the adjacent prop- 

 erty. Furthermore, provision has been made for noninfected animals 

 to come out of the infested area at any season of the year, but like 

 the ticky cattle they are subject to the restriction that they be dipped 

 in Beaumont crude petroleum or other crude oil to prevent them from 

 becoming infested in passing through the quarantined district. And 

 they must also be shipped in clean, disinfected cars, and must not be 

 driven through the infected area or unloaded therein except at points 

 designated by this department. 



In consequence of the enforcement of these quarantine regulations, 

 Texas fever has been practically prevented in the noninfected dis- 

 tricts during the last several years, and little or no hardship has been 

 caused to those stockmen handling cattle from the infected areas. 

 Previous to their adoption the tick-infested district was rapidly ex- 

 tending northward, but since the quarantine line was established and 

 rational regulations enforced it has gradually been moved farther 

 south. This problem of still further reducing the infected area is of 

 the greatest importance to the cattlemen of the South — in fact, to 

 those on both sides of the line — and one which is receiving special 

 consideration by this department as well as by many of the interested 

 States. 



As an indication of what may be accomplished by hearty coopera- 

 tion between the State and Federal Governments, it is only necessary 

 to mention that as a result of a Congressional appropriation of $82,500 

 in 1906 and $150,000 in 1907, the Bureau of Animal Industry, cooper- 

 ating with the local authorities, succeeded in cleaning up a large 

 number of counties in several States, and has released from quaran- 

 tine the following areas from July 11, 1906, to June 30, 1908:
