longer. We are fully alive to the inconvenience and loss 

 this entails on the owner, but it is inevitable, and for the 

 public good. 



Bearing in mind the opinion of Bang relative to birds 

 carrying the virus on their feet, measures should be adopted 

 where possible within the affected place to destroy or scare 

 them away. 



Attention to cattle trucks is imperative, likewise the entire 

 destruction of all faeces, and litter in them. All forage on 

 the farm or elsewhere which has run any risk of contamina- 

 tion should be destroyed, unless it can be consumed by 

 horses. 



In non-congested countries the disease may be treated 

 and the affected stock rigidly isolated. The group system 

 previously described (p. 495) must be enforced, all move- 

 ments in and out stopped. All forage required for the sick 

 which may have to be brought from a clean area must be 

 drawn by animals not affected by the disease, and even then 

 neither they nor waggons are on any account to be allowed 

 within the outer cordon. 



Disinfection of the sick and the ground on which they 

 stand must be daily practised, and a long quarantine estab- 

 lished, for safety not less than six weeks after the last case 

 has recovered. 



The standings of the sick, mangers, buckets, utensils, etc., 

 must subsequently be thoroughly disinfected, and if the 

 animals are in the open it would be well when possible 

 to plough the land and get a crop off it. Under certain 

 circumstances it may be possible to burn the surface of the 

 ground. 



During recent outbreaks in Great Britain, where the con- 

 ditions have been favourable for complete isolation, the 

 Board of Agriculture have permitted this to be done instead 

 of destruction. There are but few places where affected 

 stock could be so isolated as to be absolutely safe, and 

 nothing less than ' absolute ' should be accepted.
