68 The Lung Plague of Cattle. 



characteristic promptitude, Governor Robinson delegated 

 General Patrick as his representative, and invested him 

 Tvith plenary powers to crush out the contagion. 



This much may be allowed as showing the progressive 

 steps that led to the inauguration of the present move- 

 ment for the extermination of this disease on the West- 

 ern Continent. In turning to consider specific measures 

 for the prevention of the plague we must pass the differ- 

 ent methods under review, consider which are adapted to 

 our case and which inapplicable, and make references to 

 special measures demanded by the the conditions of par- 

 ticular localities. 



1. Protection of a Coxjntey against an Invasion op the 

 Lung Plague. 



(a) Total Exclusion of Foreign Cattle and tlieir unmanu- 

 factured Products. 



In the above it has been conclusively shown that no 

 country has been invaded by this disease that has not 

 imported cattle from without, and that countries like 

 Spain, Portugal, the Channel Islands, the Scottish High- 

 lands, Norway and Sweden that do not import but raise 

 their own cattle exclude the pestilence though it may be 

 raging fiercely at their very doors. If America were once 

 purged of this desolating pest, and if for her permanent 

 protection it were necessary to prohibit all importation 

 of cattle, immunity would be cheaply bought at such a 

 price. America can now show as good blood in her dif- 

 ferent races of cattle as is to be found in Europe ; but if 

 it were otherwise, what is the present or prospective 

 value of a Duchess to the risk "entailed on our 30,000,000 

 head of horned cattle and their offspring for all future 

 time? 



Of unmanufactured products, hides and hair are alone 

 important, and as regards both, the risk is infinitesimal. 

 Yet it cannot be denied that the contagium is preserved
