The Lung Plague of Cattle.

More recently illustrations of the existence of the dis- 

 ease in these States have been frequent, and among com- 

 paratively recent cases the author has been consulted 

 concerning a high class Jersey herd near Burlington, 

 N. J., in 1877, and a herd of imported Ayrshires in Staten 

 Island, later in the same year. 



In 1878 the town of Clinton, N. J., was invaded, the 

 infection coming through a cow that had staid for some 

 days in New York city. This was alleged to be an Ohio 

 cow, but had staid long enough in New York to have 

 contracted the affection. 



In 1847 Ayrshire cattle taken from Scotland to Den- 

 mark conveyed the plague into that country. The in-

 by the introduction of foreign cattle, but has invariably 

 stamped it out by quarantining the infected places and 

 destroying the sick cattle. One of these importations 

 consisted of Ayrshire cattle brought from Scotland in 1859. 

 A still more serious invasion took place on the occasion 

 of the late Prusso-Danish war ; the commissariat parks

 vigorously to work, drove out the pestilence, and foi 

 years past has been free from the infection. 



In 1860 Norway was infected by a cargo of Ayrshire 

 cattle, imported for the Agricultural College at Aas. The
