DISEASES OF CATTLE 343 



All cattle from the quarantined district destined to points out- 

 side of the States and Territories above named may be shipped with- 

 out inspection between November 1 and January 31, inclusive (the 

 open season), without restrictions other than may be enforced by 

 local regulations at the point of destination. At the present time 

 no cattle may go out of quarantine, except for immediate slaughter, 

 during that portion of the year included between the dates of Febru- 

 ary 1 and October 31, and known as the closed season. These cattle 

 must be slaughtered after arrival at their destination, and the regu- 

 lations of the Secretary of Agriculture concerning their handling 

 and movement shall be enforced. 



Cattle may be shipped interstate into points outside the quaran- 

 tined area for purposes other than immediate slaughter, provided 

 they are first examined and certified by an inspector of the Bureau 

 of Animal Industry to be free from infection, but cattle from the 

 quarantined area may enter only for immediate slaughter or during 

 the open season. The following is an abstract of the regulations in 

 force March 20, 1908. 



Cattle coming from the infected districts during the closed sea- 

 son can not be driven, but must be conveyed in cars or boats plac- 

 arded as containing Southern cattle, and bills of lading, waybills, 

 and conductors' manifests shall have this information written upon 

 them. When the cattle are unloaded for feeding, watering, or other 

 purpose, they must be placed in pens reserved for such animals only, 

 in which native stock is not allowed, and a large sign with the words 

 Quarantine pens or Quarantine yards must be conspicuously placed 

 on all such inclosures. On unloading at their destination, only 

 the chutes, alleyways, and pens reserved for southern cattle shall be 

 used. Before the cars or boats which carried these animals are again 

 used their entire interior must be thoroughly washed with water 

 after the removal of all litter and manure and then disinfected with 

 a mixture made of 1^2 pounds of lime and one-fourth pound of 100 

 per cent carbolic acid to each gallon of water, or with any coal-tar 

 creosote dip permitted in the official dipping of sheep for scabies, 

 provided the same is used at one-fifth the maximum dilution (five 

 times the minimum strength) specified for dipping sheep. The lit- 

 ter and manure may be disinfected as above, or, if not disinfected,, it 

 shall be stored away where cattle can not reach it during the period 

 from February 1 to October 31 of each year. All chutes, alleyways, 

 and pens usea en route and at destination but not reserved for the 

 exclusive use of southern cattle shall be similarly disinfected. Where 

 these animals are. yarded adjacent to cattle from above the line at 

 least a 10-foot space not occupied by cattle must be left between, on 

 the inside of which shall be a tight board fence not less than 6 feet 

 high, and on the outside a similar fence not less than 5 feet high. 

 The yards or portions of yards reserved for cattle of the quarantined 

 area shall be so located, or such drainage facilities shall be provided 

 therefor, that water therefrom will not flow on to the adjacent prop- 

 erty. Furthermore, provision has been made for noninfected ani- 

 mals to come out of the infested area at any season of the year, but
