112 ANNUAL REPORTS OP DEPARTMENT OF AGRICULTURE. 



Swine to the number of 254,731 were inspected and under the bu- 

 reau's supervision were given the immunization treatment against 

 hog cholera for interstate shipment from pubhc stockyards. 



Bureau stations reported 23,441 cars as arriving at points where 

 inspection is maintained, carrying animals affected with a conta- 

 gious, infectious, or communicable disease. During the year 42,069 

 cars were cleaned and disinfected under bureau supervision on account 

 of bureau regulations or on request of Canadian government officials, 

 State officials, and transportation companies. 



There were inspected by bureau veterinarians, in compliance 

 with the laws of the States to which the animals were destined, and 

 upon request of transportation companies or cattle owners, 84,400 

 cattle moving interstate for purposes other than immediate slaughter, 

 of which 26,667 were tested with tuberculin. Of the number tested 

 745 reacted, indicating that they were affected with tuberculosis, 

 and 54 showed temperatures which required them to be held as 

 suspects for further examination. 



There were also inspected by bureau veterinarians, in compliance 

 with the laws of the States to which the animals were destined, and 

 upon request of transportation companies or shippers, 25,798 horses 

 and mules, 10,228 of which were tested with mallein, 1 showing 

 typical reactions to the test, and 2 were held for further examination. 



VIOLATIONS OF LIVE-STOCK TRANSPORTATION AND QUARANTINE LAWS. 



The bureau has continued to report to the Solicitor of the depart- 

 ment, for presentation to the Attorney General for prosecution, 

 cases of apparent violations of live-stock transportation and (Quaran- 

 tine laws. Many of these cases have required special investigation 

 on the part of bureau employees, such as interviewing witnesses and 

 examining railroad and other records for the completion of evidence. 

 Six bureau employees were regularly assigned to this work, though 

 the greater part of the work of collecting evidence and preparing 

 and submitting reports is done by bureau employees at stockyard 

 centers, in connection with their other duties. The enforcement of 

 the so-called 28-hour law has resulted in better facilities being pro- 

 vided for the feeding, watering, and handling of live stock in transit. 



TRANSFER OF WORK. 



The supervision of the interstate transportation of live stock 

 and the work relating to the enforcement of the 28-hour law have 

 been transferred to the Field Inspection Division, effective July 1, 

 1918. 



PATHOLOGICAL DIVISION. 



The Pathological Division, which was supervised by John R. Moh- 

 ler in addition to his duties as assistant chief of the bureau up to 

 December 10, 1917, and of which John S. Buckley has since been 

 acting chief, has been engaged mainly, as heretofore, in the scientific 

 investigation of diseases of animals and in assisting in the control of 

 viruses, serums, and other remedies used in the treatment of live 

 stock. Special cooperation with the War Department in dealing with 

 diseases of horses and mules was a feature of the year's work.
