CONTAGIOUS DISEASES OF ANIMALS. 
Ill 
has resulted in the complete eradication of the malady. In New 
York, in 1879, the same measures rooted out the disease from 
four of the eight infected counties, and restricted it to eight 
herds, which were preserved for lack of funds in two more of 
the counties, while in Kings County and the adjacent parts of 
Queens, where local authorities had successfully opposed our 
work, the malady remained widely prevalent. While advocating 
the full efficacy of this method, it is unnecessary to go into minor 
particulars further than to sa}^ that no additions from the public 
market should be allowed to herds in infected districts, nor ex¬ 
cept by natural increase or by special permit, from healthy dis¬ 
tricts, or through close markets which receive stock from such 
healthy districts only ; that every death in a herd in such pro¬ 
claimed infected districts should be promptly reported, and the 
carcase examined by a veterinary inspector; that no cattle should 
be moved from such herds in infected districts except to immedi¬ 
ate slaughter, where examination of the carcase can be made by a 
veterinary inspector; or such movement should only be allowed 
after the herd and district have been certified by the inspector to 
have been sound and without dangerous additions for six months; 
that all infected animals, or far better, every infected herd should 
be promptly slaughtered ; and that a thorough disinfection should 
be made of all premises when diseased animals or their fresh pro¬ 
ducts had been. 
I have always held that the only sound and just method of 
dealing with this disease must be directed and sustained by the 
National Government. I quote from my monograph on the lung 
plague, published in 1879. 
“ The plague threatens to reach our southern and western 
ranges, whence it will be as impossible to eradicate it as from the 
Russian steppes, Australia and South Africa, and from which 
continuous accessions of infection will be thrown upon our Mid¬ 
dle and Eastern States, and shall we hesitate to call upon the 
National Government to interfere ? This is a question of in¬ 
comparably more moment to the western and middle States than 
to Delaware, Maryland or Virginia. To throw the burden of the 
extinction of this disease on these States is as impolitic as it is
