CONTAGIOUS PLEURO-PNEUMONIA IN CATTLE 413 
made an attempt to eradicate it in 1879 but were not successful. 
Late in 1883 the contagion was carried to Ohio, probably by cattle 
purchased in the vicinity of Baltimore, Md., to which place it had 
extended previous to 1868. From the herd then infected it was 
spread by the sale of cattle during 1884 to a limited number of herds 
in Illinois, to one herd in Missouri and two herds in Kentucky. By 
codperation between the United States Department of Agriculture 
and the authorities of the states, it was found possible to prevent its 
further spread and to completely eradicate it after a few months.* 
In 1886, pleuro-pneumonia was discovered in some of the large 
distillery stables of Chicago and among cows on neighboring lots. 
This led to renewed efforts to secure its eradication. Congress, in 
1887, enlarged the appropriation available for this purpose and gave 
more extended authority to the Bureau of Animal Industry. During 
the same year the disease was stamped out of Chicago and has not 
since appeared in any district west of the Alleghany Mountains. 
The work of eradication was at the same time commenced in all 
of the infected States. Before the end of the year 1889 Pennsylvania, 
Delaware, Maryland, the District of Columbia, and Virginia had 
been freed from the disease. More difficulties, however, were encoun- 
tered in the States of New York and New Jersey on account of the 
larger territory infected and the density of the population. The last 
animal in which the disease appeared in the State of New York was 
slaughtered early in 1891 and the last one affected in New Jersey met 
the same fate early in the spring of 1892. 
On the 26th day of September, 1892, the following proclamation 
was issued, declaring the United States to be free from this disease. 
PROCLAMATION—ERADICATION OF PLEURO-PNEUMONIA 
U. S. DEPARTMENT OF AGRICULTURE, 
OFFICE OF THE SECRETARY. 
To ALL WHOM IT MAY CONCERN: 
Notice is hereby given that the quarantines heretofore existing in the counties of 
Kings and Queens, State of New York, and the counties of Essex and Hudson, State of 
New Jersey, for the suppression of contagious pleuro-pneumonia among cattle, are 
this day removed. 
The removal of the aforesaid quarantines completes the dissolving of all quarantines 
established by this Department in the several sections of the United States for the 
suppression of the above-named disease. 
*It was the presence of this disease with its menace to the cattle industry of the 
United States that led Dr. D. E. Salmon to urge the establishment of the Bureau of 
Animal Industry in 1884.
