Liung Plague in South Africa. 



disease broke out three months after their arrival, and 

 was limited by the slaughter of all native cattle with 

 which the Ayrshires had come in contact, and by the 

 strict quarantine of the Ayrshires themselves. Since 

 that time Norway has remained sound. 



Sweden imported the Lung Plague from England, by 

 cattle imported in 1847. By stringent measures of sup- 

 pression it was speedily exterminated, and this impunity 

 has since been maintained. 



Oldenburg derived the disease from England through 

 Ayrshires imported for breeding purposes in 1858. This, 

 together with other invasions, she has crushed out by the 

 remorseless use of the pole-ax. The same remark applies 

 to Mecklenburg-Schwerin and Switzerland. 



For the history of the introduction of this plague into 

 Australia see "Infection through Pastures." Its convey- 

 ance to the Cape of Good Hope was described by Eev. 

 Daniel Liadley, missionary to South Africa, before the 

 Massachusetts Legislative Committee, in 1860. 



The importation took place in 1854 in the body of a 

 bull brought from Holland by a gentlemen of Cape Town 

 with the view of improving his stock. The bull was 

 about two months on the passage, and had been six 

 weeks at the Cape before any sign of sickness appeared 

 in him. He died, but conveyed the disease to a great 

 number of cattle, and it had spread very widely before 

 the colonists suspected its true nature. The Cape is a 

 great unwooded and unfenced pasture-land, dotted with 

 thickets and jungles, and over this the cattle, the source 

 of the colonist's wealth, are scattered in herds of from 

 one to five hundred head on an average. Wherever liona 

 and tigers have been exterminated these cattle are allowed 

 to roam day and night where they please ; they accord- 

 ingly wander long distances, and herd mingles with herd 

 from one side of the country to the other. All the prod- 

 uce of the country is brought from the interior to the
