524 BOARD OF AGRICULTURE. [Pub. Doc. 



Cattle from the Reijublic of Mexico may be admitted into the United 

 States to remain below said Federal quarantine line after inspection, 

 according to law; but said cattle shall not be permitted to cross said 

 quarantine line otherwise than by rail for immediate slaughter, except 

 by special permit from the inspectors of the Bureau of Animal Indus- 

 try, issued according to the regulations of the said Bureau ; and no per- 

 mit shall be issued except for cattle free from splenetic, or Texas, fever, 

 or from contact therewith during the three months preceding the 

 issuance of said permit, and which have been grazed in a locality free 

 from infection of such fever. 



Notice is hereby given that cattle infested with the Boophilus bovis, 

 or southern cattle tick, disseminate the contagion of splenetic, or south- 

 ern, fever (Texas fever) ; therefore cattle originating outside of the dis- 

 trict described by this order or amendments thereof, and which are 

 infested with the Boophilus bovis ticks, shall be considered as infectious 

 cattle, and shall be subject to the rules and regulations governing the 

 movement of southern cattle. 



Stock yards companies receiving such cattle shall place the same in 

 the pens set aside for the use of southern cattle, and transportation com- 

 panies are required to clean and disinfect all cars and vessels which 

 have contained the same, according to the requirements of this depart- 

 ment. 



The losses which formerly occurred to the owners of susceptible 

 cattle, both in the interstate and export trade, hj the contraction of this 

 disease from exposure in unclean and infected cars and pens, and by 

 means of the manure carried in unclean cars from place to place, became 

 a matter of grave and serious concern to the cattle industry of the 

 United States, until this danger was removed by the inspection of this 

 department. It is absolutely essential, therefore, that this cattle industry 

 should continue to be pi'otected as far as possible by separating the dan- 

 gerous cattle and by the adoption of efficient methods of disinfection. 



Inspectors are instructed to see that disinfection is properly done, and 

 it is expected that transportation and stockyards companies will promptly 

 put into operation the above methods. 



All prior orders conflicting herewith are hereby revoked. 



J. Sterling Morton, 

 Secretary. 



The restriction placed upon traffic in cattle for feeding purposes 

 and the comparatively complete separation of infected cattle from 

 the others in the large stock yards of this country, cut down losses 

 from this source to a minimum, yet outbreaks resulting in a total 

 of thousands of dollars' loss have since annually occurred, due to 

 evasions of the law along the quarantine line and in unprotected 

 places. 



In the present instance the loss was brought about by the unload- 

 ing of quarantine cattle into pens used by other cattle and by admit- 

 ting other cattle thereto, in direct violation of Regulation No. 2.
