Closure of Pastures : Registration of Herds. 8S 



We have already seen the danger of infected pastures 

 and notably in the case of Australia, and as these cannot 

 be purified artificially we must allow time for the action 

 of nature's great natural disinfectants. The time neces- 

 sary will vary somewhat in different cases, thus in a mild 

 climate with frequent alternations of rain and sunshine 

 it may be considerably less than in the dry Australian 

 cHmate, or in the winter season of our northern States 

 when everything is for months bound up in frost. Three 

 months may be fairly accepted as a good average. 



(g) Make a Register of each Infected Herd vnth a Per- 

 sonal Description of every Animal. 



By adopting this precaution a perfect control may be 

 kept up by non-professional inspectors, and the frequent 

 visits of the more expensive veterinarian largely dis-

 animal disappears it must be accounted for and no beast 

 can be replaced by another without detection. 



For this purpose a personal description is usually a 

 better safeguard than any mark or brand which may be 

 counterfeited. 



NEED FOE SPECIAL MEASURES IN CITIES. 



The eradication of the Lung Plague from fenced coun- 

 try districts is a very simple affair, to be easily and 

 speedily accomplished at but little cost, but when we 

 come to the cities we find a totally different state of 

 things, requiring special restrictive measures. To illus- 

 trate this I must enter somewhat into the nature of the 

 city dairy interest. 



Supply of Fresh Cows. 



Under ordinary circumstances the fresh cows are sup- 

 plied from country districts and most of them come in 

 Bound. "When, however, disease exists in the adjacent 

 country the city is the readiest market for animals from
