animal tliat is propagating the virus is a danger of the gravest 
kind. 
The manifest remedy is to extirpate the poison. Now, as prac¬ 
ticed over six different States, in all sorts of buildings and fields, 
and among all sorts of people, no system of quarantining and dis¬ 
infecting of the sick can ever prove perfectly efficient. It is be¬ 
sides so expensive that a destruction of the infected herd and the 
payment of an indemnity by the State is far more economical. 
The system of killing the sick, avoids all danger of the diffusion 
of the disease, or of laying up the poison for future outbreaks, 
and it is that wjiicli has been proved in all countries to be the only 
successful course with fatal contagious diseases of animals that are 
not native to the soil. 
Inoculation, like treatment, or like separation and disinfection, 
has never thoroughly eradicated this disease from any country. 
Belgium, Holland, England, France, Austria, New York and New 
Jersey, are illustrative examples. It lessens the losses in the in¬ 
dividual herd, as would sound medical treatment, but it multiplies 
the poison indefinitely in the system of every inoculated animal, 
lodges it in the buildings and widens the area of infection. It 
lops off the terminal twigs of this mighty upas, but fails to strike 
the roots, and in place of killing it, gives strength and vigor for 
renewed growth. The man who practices inoculation or advocates 
it, contributes to the preservation and propagation of the disease, 
helps its extension to our western herds, and does his part towards 
a general infection, and the paralysis and ruin of our mighty and 
growing live stock interest. More, in this State the operation 
brings condemnation upon the inoculated animals, for thev must 
now be considered as infected and subject to be slaughtered under 
the law. 
As with the lung fever, so with other fatal animal contagions, 
such as rinderpest, bovine variola, swine plague, glanders, &c. 
Veterinary sanitary science has a great work to accomplish and 
bright laurels to win. She has but to go in and conquer. Be¬ 
sides the field of specific disease-poisons, she has to contend with 
an extended domain of parasiticism, and many of the parasites of 
the lower animals ar equally inimical to man, so that this is one of
