Unfcnced Pastures to he Disused. 83 



Stock has been clear of Contagious Disease for the Fast Six 

 Months Immediately Preceding. 



Here the danger is the same as in the case of fairs anc 

 markets, and without the restriction named, apparently 

 sound cattle from infected herds or premises are seni 

 npon common pastures and when later the different herds 

 are taken back by their respective owners they carry witii 

 them the seeds of sickness and death to others. 



(/) Prohibit Absolutely the Pasturage of Cattle on Un- 

 fcnced Grounds and Highways. 



In infected localities pasturage on roads and open lota 

 is one of the most fertile sources of infection. Healthy 

 herds turned out in this way come in contact with neigh- 

 boring or passing infected ones, or with the places where 

 they have immediately preceded them ; apparently sound 

 cattle from infected herds carry the virus to healthy ones 

 or breathe upon and soil the grass on which these after- 

 ward browse, and thus the malady is spread ere any sus- 

 picion is aroused. Many think to save their stock by 

 having them herded or tethered, but the idea is a most 

 fallacious one, as may be seen from the examples of the 

 transmission of the contagium through pastures in Aus- 

 tralia and elsewhere. The only course of safety is to 

 exclude all cattle from open lots and highways and to 

 utilize the products of such by mowing and soiling when 

 this is necessary. 



(g) License Stud Bulls in Healthy Herds to Serve Cows 

 from Sound Herds. 



The danger of contagion from sending cows from in 

 fected herds to healthy bulls, and vice versa, necessitates 

 this provision. Yet as the business usually demands 

 dispatch, a license may be given for all safe bulls in the 

 district and a running permit to the owners of sound 

 herds of cows empowering them to take cows to the 

 nearest of such bulls without loitering or pasturing them 

 on the way.
