ginia and North Carolina not included in the quarantined area. Dur- 

 ing the month of January and the last seventeen days of December in 

 each year cattle of the quarantined area of any State or Territory may 

 be moved interstate therefrom for purposes other than immediate 

 slaughter under the above-mentioned restrictions into that portion 

 of the State of Oklahoma not included in the quarantined area. 



All cattle from the quarantined district destined to points outside 

 of the States and Territories above named may be shipped without 

 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 from the shaded area shown on the map in 

 Plate LI, except for immediate slaughter, during that portion of the 

 year included between the dates of February 1 and October 31, and 

 known as the closed season. These cattle must be slaughtered after 

 arrival at their destination, and the regulations of the Secretary 

 of Agriculture concerning their handling and movement shall be 

 enforced. 



Cattle may be shipped interstate from the black area indicated in 

 Plate LI to points outside the quarantined area for purposes other 

 than immediate slaughter, provided they are first examined and cer- 

 tified by an inspector of the Bureau of Animal Industry to be free 

 from infection, but cattle from the shaded area may enter the black 

 area only for immediate slaughter or during the open season. The 

 following is an abstract of the regulations in force March 20, 1908:

 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 11 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 litter 

 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 used en route and at destination but not reserved for the
