FOREST SERVICE. 395 



Bureau of Animal Industry. Reports of the existence of glanders 

 among range horses, of the spread of anthrax among cattle, etc., were 

 investigated by members of the Bureau of Animal Industry at the 

 request of forest officers. 



During the year the Forest Service assisted the Bureau of Animal 

 Industry to construct a quarantine drift fence along the international 

 boundary in California, the greater part of the fence being within the 

 Cleveland National Forest. Its purpose is to prevent the intrusion 

 from Mexico of cattle infested with the Texas fever tick. 



The Wichita Forest in Oklahoma, being south of the quarantine 

 line, has since its creation been so infested with Texas fever ticks that 

 heavy losses have occurred among domestic animals introduced from 

 other States, and the welfare of the game animals within the game 

 refuge, particularly the buffalo and elk, has been seriously threatened, 

 three head of buffalo having died of the disease shortly after arrival 

 at the refuge several years ago, and losses among the remaining 

 buffalo being prevented only by constant attention and the spraying 

 of the animals at frequent intervals. Plans were therefore made, in 

 cooperation with the Bureau of Animal Industry, to free the forest 

 from ticks. The permittees provided five dipping plants and ade- 

 quate facilities for the dipping of all cattle within the Forest, and the 

 Forest Service provided all material needed for the construction of the 

 fences requirea to divide the ranges and control the stock. The dip- 



fing of the cattle was under the direction of the Bureau of Animal 

 ndustry, and at the close of the year arrangements for the dipping of 

 all stock were well under way. 



The Arkansas and Ozark National Forests are both situated south 

 of the quarantine line and well within the Texas fever zone; stock 

 holdings are smaU and scattered; and the work of tick eradication 

 within the Forests difficult and costly. For these reasons, there has 

 been no effort made to free these Forests from ticks. The forest 

 officers and members of the Bureau of Animal Industry have, how- 

 ever, succeeded largely in counteracting the local belief that the tick 

 can be controlled by burning over the lands each year, and the number 

 of fires set for that purpose has been materially reduced. 



The relations between the Forest Service and the stock sanitary 

 boards of the different States were entirely harmonious, and the 

 Service cooperated fully in the enforcement of State sanitary regula- 

 tions. Cooperation with the Colorado State Board of Health con- 

 sisted in posting State sanitary notices throughout the National 

 Forests of the State and bringing to the notice of all Forest users the 

 requirements of the State sanitary laws.
