CONTAGIOUS DISEASES OF DOMESTICATED ANIMALS. 75 



of Virginia permaueDtly infected with southern cattle fever as correctlj' 

 as this could possibly be done. Parts of the line have been retraced 

 three and four times iu order to have it satisfactorily located. 



NORTH CAROLINA. 



The Blue Kidge Mountains of Xorth Carolina are now looked upon 

 by the i)eoi)le of this State as the practical boundary line of the district 

 permanently infected with southern fever. At some points, as in 

 Wilkes County, the infection has not quite reached the mountains, and 

 at one other point it has crossed the ridge and invaded Henderson 

 County. The laws of the State, however, make the Blue Ridge the line, 

 and prohibit the movement of cattle from the eastern counties at all 

 seasons of the year. 



SOUTH CAROLINA AND GEORGIA. 



The whole territory of South Carolina seems to have been overrun 

 with this infection. The Blue Eidge ^lountains, which form a part of 

 the northwestern boundary of the State, have here been crossed by this 

 contagion and are no longer to b: considered as the line. The infected 

 district beyond these mountains is, however, at present of small extent, 

 and the advance is so slow as to be scarcely appreciable. 



The small portion of Georgia which has heretofore been considered 

 free from this infection is being rapidly overrun; and it is now doubt- 

 ful if any of even the northern tier of counties can be considered entirely 

 free. The mountain sec ions are no: so thoroughly- infected, and it is 

 ])robable that Towns, Union, and Fannin Counties are practically fi'ee 

 from the i)ermaneut infection. 



Whitfield and Murray Counties have been quite thoroughly inspected 

 and the commons of both found to be infected in all parts. Many of 

 the farms are also infected, but some still remain free, especially near 

 the northern boundary. Cattle taken from these counties to the mount- 

 ain ranges of Gilmer for pa stnre have not so far as has been ascertained 

 caused any outbreaks of disease. This is probably due to the fact that 

 Gilmer County is also pretty thoroughly overrun. 



Here, as in many other localities, there are evidences of a different in- 

 tensity of the contagion in various parts of the counties, but more par- 

 ticularly in different sections of the State. Thus, cattle which have 

 pastured on the ordinary infected ranges of Whitfield County without 

 harm, have become diseased as a consequence of feeding along the trails 

 and on the commons where cattle from Southern Georgia had lately 

 grazed. The movement of bovine animals from one farm to another or 

 from one county to another is also considere<l dangerous. The fatigue 

 induced by driving is without doubt one of the factors in producing 

 the disease in such cases. Even cattle from the extreme south often 

 succumb whe ; exhausted by long journeys. Similar facts have long 

 been noticed with other dise.ases, and particularly witli antlirax. cattle
