522 ANNUAL REPORTS OF DEPARTMENT OF AGRICULTURE. 



or comniunicable disonscs must be snbmidod to rij^id inspection by 

 reprosoiitativos of tlie Bureau of Animal Industry and pronounced 

 free from disease before they are allowed to occupy the forest 

 ranges. In this way the forest lands are protected from dangerous 

 infection. The relations between members of the Forest Service and 

 the Federal and State oHicers charged with the duty of enforcing 

 quarantine regulations and stock sanitary laws continued thoroughly 

 harmonious and closely cooperative. 



No inspection of sheep was required within districts 1, 5, and 6. 

 Lip-and-leg ulceration developed to a limited extent on the Custer 

 Forest, in Montana, but quarantine was not considered necessary. 

 Inspection of sheep and presentation of certificates showing free- 

 dom from disease was required upon the Durango, San Juan, Coche- 

 lopa, Montezuma, Uncompahgre, and Kio Grande Forests, in Colo- 

 rado; the Cache, Caribou, and Pocatello Forests, in Idaho; and all 

 forests in the States of New Mexico, Nevada, and Utah, excepting 

 the Ashley Forest. Sheep scabies has been so thoroughly eradicated 

 in Arizona and the lip-and-leg epidemic is so Avell under control in 

 Wyoming that inspection was not deemed necessary in these States 



Inspections of cattle for mange were required upon the Fremont 

 and Deschutes Forests in Oregon, the Kansas Forest in Kansas, and 

 the Lewis and Clark Forest in Montana. 



Texas fever occurs only within the Cleveland, Wichita, Arkansas, 

 and Ozark National Forests, and within the two forests first named 

 it is rapidly being brought under control. During the year the 

 Forest Service assisted the Bureau of Animal Industry in the con- 

 struction of a 6-mile extension of the quarantine drift fence along the 

 international boundary line in southern California and in the survey 

 of a right of way for an additional extension which will be 33 miles 

 in length. The completion of this fence will prevent the movement 

 of tick-infested cattle across the international boundary. Three graz- 

 ing permits for 106 head of cattle and horses were canceled on the 

 Cleveland Forest at the request of the Bureau of Animal Industry 

 to strengthen the quarantine. It is anticipated that the Cleveland 

 Forest will be entirely freed of Texas fever within a comparatively 

 short time. On the Wichita Forest the periodic dipping of permitted 

 cattle was continued under the supervision of a representative of the 

 Bureau of Animal Industry. The drift fences and dipping vats con- 

 structed during the previous year are fully accomplishing the pur- 

 poses for which they were designed, and it is believed that the forest 

 will be completely freed of ticks within a year or so. On the Arkan- 

 sas and Ozark Forests no effective progi^ess in tick eradication can at 

 present be made, but the residents of these forests are awakening to 

 the importance of this work and ultimately it is hoped to secure their 

 hearty support and cooperation, after which steps will be taken to 

 clean the forests. 



PBOTECTION AGAINST WILD ANIMALS. 



Predatory animals harmful to live stock and game animals were 

 killed by forest officers as follows:
