PLEUROPNEUMONIA IN CATTLE.

tering order, and secure the admission of American beeves and 
store cattle to the English markets on the same terms with the 
native. It is better far that every one, and above all every 
member of Congress, should face the truth,' evident from the first 
to those acquainted with the malady, and now attested by four 
years of British restriction, that nothing short of the absolute and 
undeniable extinction of this disease in the United States will 
reopen the British market to our live cattle , and save us those 
millions that we are now every year prodigally , and we might 
also say insanely , throwing atoay. 
IMPORTANCE OF THE EXTINCTION OF LUNG PLAGUE IN AMERICA TO 
OUR HOME CATTLE INDUSTRY. 
The continued existence of lung plague in America will 
sooner or later lead to the infection of our western herds—the 
source of our cattle traffic—and this will entail the speedy infec¬ 
tion of all the channels of that traffic and of the country at large. 
ACTIVITY OF CATTLE TRAFFIC FROM INFECTED DISTRICTS. 
The cattle traffic from the infected regions in the eastern 
States to the west is more active and extensive than was that 
between the European continent and the British Isles at the time 
of the infection of Ireland in 1839 ; more than was that between 
England and Australia when the latter was infected in 1858; 
more than was that between Holland and South Africa when 
Cape Colony became infected in 1854; more lhan was that 
between Holland and Massachusetts when that commonwealth 
succumbed to the disease in 1859; and incomparably more than 
was that between England and New Tork when the germ of our 
present infection was brought from the mother country in 1848. 
The infection of Ireland and Massachusetts was effected in each 
case by the introduction of a limited number of Hutch cattle— 
four or five—while all the other states named were each infected 
by the arrival of a solitary animal, and at a time when no cattle 
traffic of any account was carried on between the countries in¬ 
volved. (See our last year’s report, pages 9, 14, 17, 19 and 21.) 
The importations into these countries at the times referred to
