DISEASES OF SHEEP. 89 



to keep them in the stable. If no other but the infected 

 one is at hand, it must be previously cleaned very carefully. 

 The dung should be removed and buried, or ploughed 

 down deeply. Cribs, mangers, stands, etc., are covered 

 with whitewash containing one pound of chloride of lime 

 for every pail. It is well to have a different keeper for the 

 sick animals, to prevent infection of the healthy ones from 

 the virus, which might adhere to his shoes. 



When the lameness has. disappeared, when new and tol- 

 erably firm horn has formed on the wound, and when the 

 latter is dry and firmly united with the flesh, the sheep is 

 removed from the sick flock. Since, however, it is not yef 

 safe to return it to the healthy ones, it should be considered 

 convalescent, and separated for at least two or three weeks 

 from both the sick and the healthy flocks. It must be fre- 

 quently examined, and finally made to walk through 

 chloride of lime water in the way described, before return- 

 ing it to the healthy sheep. When the epidemic has disap- 

 peared entirely from the flock, the stables, etc., should be 

 thoroughly cleansed. 



No preventive is known, because the disease arises solely 

 from contagion. It commences by attacking a few head at 

 first, and spreads gradually and slowly to the rest. 



If the epidemic has broken out in the neighborhood, 

 contagion from coming in contact with other flocks should 

 be carefully guarded against. The sheep should be kept 

 as far as possible away from such localities, and all com- 

 munication among sheep, as well as all contact with the shep- 

 herds and dogs, avoided. Infected herds should not be per- 

 mitted to pass through places where the disease has not ap- 

 peared. After buying sheep, they should be kept isolated 

 for one or two weeks, and carefully observed. It is recom- 

 mended to keep a sort of quarantine always, even if the 

 vicinity is free from the epidemic.
