BUREAU OF ANIMAL INDUSTRY. 107 



FIELD INSPECTION DIVISION. 



The Field Inspection Division, under A. W. Miller, chief, has car- 

 ried on work for the control and eradication of certain animal 

 diseases. 



INSPECTION FOR FOOT-AND-MOUTH DISEASE 



As a precaution against the reappearance of foot-and-mouth dis- 

 ease the assignment of experienced veterinarians to make careful 

 inspections for this disease in all cattle, sheep, and swine received at 

 public stock3'ards was continued. Numerous suspected outbreaks 

 of this disease reported to the bureau were investigated promptly, 

 with negative results in all instances. 



ERADICATION OF SCABIES. 



In the work of eradicating sheep scabies in cooperation ^vith State 

 officials, 19,630,126 inspections of sTieep were made in the field by 

 bureau employees, and 5,585,543 sheep were dipped. 



The work of eradicating the disease in Montana and Nevada, 

 where outbreaks occurred during the latter part of the preceding fis- 

 cal year, was practically completed. During the year the bureau, 

 in cooperation with the State officials of Idaho and Wyoming, was 

 engaged in combating a considerable spread of the infection in those 

 States, where for several years previously the disease had existed to 

 a very limited extent, and satisfactory progress was made toward its 

 efimination from affected herds. During the year 1,367 square 

 miles in Louisiana were placed under quarantine on account of the 

 prevalence of sheep scabies therein, and 239,484 square miles in 

 Texas were released from such quarantine. 



In the eradication of cattle scabies in cooperation with State offi- 

 cials, bureau employees in the field made 1,829,532 inspections of 

 cattle, and 642,831 cattle were dipped. A few scattered outbreaks of 

 the disease, which occurred in several States, were quickl}^ brought 

 under control. The remaining area under Federal quarantine, 3,817 

 square miles in Texas, was released. 



Horses and mules to the number of 6,755 were inspected for 

 scabies, and the dipping of 545 of these animals was accomplished 

 under bureau supervision. 



ERADICATION OF DOURINE. 



Satisfactory progress was made in the work of eradicating dourine 

 in most of the States in which the disease prevailed. No infected 

 animals were found during the fiscal year in Iowa and Nebraska, 

 where the work had been completed the preceding year, and only a 

 small number in North Dakota and Wyoming. Although a con- 

 siderable number of infected animals were found in South Dakota 

 and Montana, the good progress of previous years in the eradication 

 of the disease in those States was continued. New areas of infection, 

 in addition to the large areas in which it was known that the disease 

 prevailed, were found in Arizona and New Mexico. A very large 

 proportion of the infection in those two States was found among 

 horses ranging on Indian reservations, and the work of eradicat- 

 ing the disease on the reservations was extremely difficult, because 

 most of the Indian horses are wild ponies, ranging in rough and
