saliva and tears ; catarrh with redness of all visible mucous 

 membranes, diarrhcea, peculiar foetid odour of the breath, 

 great prostration, and high body temperature. 



It is at about the sixth day of the infection that the 

 symptoms are best observed. 



The methods to be adopted to get rid of Einderpest de- 

 pend upon the country ; in the small and congested British 

 Islands the question of treatment cannot be entertained, 

 the destruction of all infected and all in-contacts is impera- 

 tive. In this respect the term in-contacts must be liberally 

 interpreted. In the case of a farm it means the destruc- 

 tion of every ruminant in the place, with complete isolation 

 of the other animals of the farm for a period of at least 

 two months. 



The most ruthless destruction is in the end an 

 economical proceeding, but for staying the extension of 

 disease it will not prove effective unless every living 

 animal, man included, is kept isolated and within a cordon 

 which must at once be drawn as far as possible around the 

 infected area. 



Whatever passes into that farm by accident, be it trades- 

 man, or dog, must remain there ; the man until thoroughly 

 disinfected, the dog until the outbreak is over. The place 

 is to be as isolated as if it lay in the middle of the Atlantic 

 Ocean. 



Those whose duty it is to watch the cordon, should be 

 provided with means of destroying all small animals which 

 may be wandering about, even birds should be destroyed. 



One of the most important lessons to be learned from 

 experience in dealing with epizootic diseases is the weak- 

 ness of even the strictest sanitary cordon ; neither fences 

 nor bayonets can be depended upon to keep out disease, for 

 the number of leakages in the best established system are 

 manifold. 



In South Africa, Cape Colony spent thousands of pounds 

 in erecting a wire fence along its immense frontier to keep 

 out Cattle Plague from the north, and guarded every inlet, 

 still the disease found its way in, for the possible leakages
