FIELD INSPECTION DIVISION. 



A. W. MiLLEE, Chief. 



INSPECTION FOR FOOT-AND-MOUTH DISEASE. 



Following the eradication of foot-and-mouth disease, and as a pre- 

 caution against its reappearance, experienced veterinarians stationed 

 at public stockyards were specially detailed to make careful inspec- 

 tions for this disease in all receipts of cattle, sheep, and swine. All 

 suspected outbreaks reported to the bureau were investigated 

 promptly, but no case of the disease was found during the j^ear. 



ERADICATION OF SCABIES. 



In the work for the eradication of sheep scabies in cooperation with 

 State officials 18,615,071 inspections of sheep were made in the field by 

 bureau employees, and 5,539,919 sheep were dipped. Outbreaks of 

 the disease which occurred during the fiscal year in Montana and 

 Nevada, traceable to shipments into these States, in which the disease 

 had not existed for several years, are being rapidly brought under 

 control. Work fo-r the eradication of sheep scabies was begim in 

 Texas during the fiscal year by the bureau in cooperation with officials 

 of that State. During the fiscal year 9,702 square miles in California 

 and 20,061 square miles in Colorado were released from quarantine as 

 a result of eradication accomplished. 



In the eradication of cattle scabies in cooperation with State 

 officials bureau employees in the field made 1,924,970 inspections of 

 cattle, and 343,517 cattle were dipped. A number of outbreaks of 

 cattle scabies occurred during the year in several States in localities 

 in Avhich the disease had not been prevalent for a number of years. 

 Prompt action was taken to prevent the spread of the disease and to 

 eradicate it from the affected herds. 



Horses and mules to the number of 17,567 were inspected for 

 scabies, and the dipping of 60 of these animals was supervised by 

 bureau employees. 



ERADICATION OF DOURINE, 



Although some new areas of infection were discovered during the 

 fiscal year, good results have been accomplished in the work of 

 eradicating dourine. This work has been practically completed in 

 Iowa and Nebraska and is nearing completion in North Dakota and 

 Wyoming. Considerable areas of infection still remain, however, in 

 Arizona, Montana, New Mexico, and South Dakota. Officials of the 

 States concerned and most of the horsemen in the infected areas have 

 cooperated Avith the bureau in a satisfactory manner. As funds have 

 been available, the bureau is continuing the practice of paying one- 

 half of the appraised valuation of infected horses destroyed, such 

 share not to exceed $100 in any case. The number of animals tested 

 and the results of tests are reported under the heading of the Patho- 

 logical Division. The percentage of reactions is 2.47, as compared 

 with 3.1 for the preceding year. A very large proportion of the 

 infection was found among horses ranging on Indian reservations.
