LIVESTOCK SANITARY WORK IN INTERSTATE COMMERCE. 



In the course of supervising the interstate transportation of live- 

 stock to prevent the spread of animal diseases, bureau employees at 

 market centers inspected 22,063,290 cattle, of which 24,028 Avere 

 dipped under bureau supervision in order that they might continue 

 in interstate commerce. Sheep to the number of 23,472,528 were also 

 inspected for communicable diseases, and of these 2,744,481 were 

 dipped under bureau su])ervision to comply Avith the regulations of 

 the department or of the States of destination. Swine inspected 

 numbered 39,754,970, and 574,558 of these were vaccinated a^^ainst 

 hog cholera under bureau supervision for distribution as feeding or 

 breeding animals. 



Upon request of transportation companies and shippers or to com- 

 ply with laws of States to which shipments were destined, bureau 

 veterinarians inspected 36,393 horses and mules, of which 23,742 were 

 tested with mallein, 5 showing reactions. 



During the j-ear 27,363 cars carrying animals affected with com- 

 municable diseases were received at bureau stations. In compliance 

 with department regulations or on request of Canadian Government 

 officials, State officials, or transportation companies, 47,434 cars were 

 cleaned and disinfected under bureau supervision. 



To guard against the recurrence of foot-and-mouth disease, careful 

 inspections of all ruminants and swine received at public stockyards 

 were made by experienced veterinary inspectors specially assigned 

 to that work, as has been the practice for a number of years. All sus- 

 pected outbreaks of the disease reported to the bureau were promptly 

 investigated, without a single case having been discovered. 



VIOLATIONS OF LIVESTOCK TRANSPORTATION AND QUARANTINE LAWS. 



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

 ment, for presentation to the proper officials of other departments, 

 cases of apparent violations of livestock transportation and quaran- 

 tine laws. Many of these cases have required special investigation on 

 the part of bureau employees, such as interviewing witnesses and ex- 

 amining railroad and other records. Five 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 provided for the feeding, watering, and han- 

 dling of livestock in transit. 



TICK ERADICATION DIVISION. 



The administrative work for the control of the spread of Texas 

 or tick fever and the eradication of cattle ticks which transmit this 

 disease has been continued bv the Tick Eradication Division under 

 the direction of Dr. R. A. Ramsay, chief, in cooperation with the 

 authorities of the Southern States affected.
