TREATMENT OF HOG CHOLERA.

very successful as a cure. We regret to hear that in Dr. Peters’ 
hands it has failed as a preventive, for most of us have placed 
our faith in its preventive action. 
As is also well known, the Department of Agriculture, Bu¬ 
reau of Animal Industry, last year used considerable serum in 
Page County and have this year continued the work on a larger 
scale. 
In an address at Omaha last September, Dr. Salmon, chief 
of the Bureau, stated in regard to the results obtained last year, 
that of about two hundred and fifty animals in infected herds 
over seventy-five per cent, were saved by the serum treatment. 
He also said that this year (up to September) the results had 
been better, indicating that eighty per cent, of the animals in 
infected herds could be saved. 
I regret to say that in the limited number of experiments I 
have recently made for the Bureau the results have not been so 
good. 
I have, however, only dealt with herds where the disease was 
very virulent and had gained a good foothold before the serum 
was used, and I presume did not have the strongest serum. It 
seems to me that it is not reasonable to suppose that any treat¬ 
ment will cure those that are badly diseased, and from what I 
have learned from different sources there is nothing yet within 
reach that will do this. While we may remain unable to cure 
the sick, especially those showing well marked symptoms, I be¬ 
lieve, however, that a serum of sufficient anti-toxic power can be 
obtained to render a certain per cent, at least of swine immune. 
As to what per cent, ought to be saved in this way I am not 
prepared to say. 
The Bureau has a bulletin in print giving some results of 
serum work. This will no doubt give us much information 
on the serum treatment. 
Granting that it will be so successful as to warrant its use, 
will it be practical to use it? Can it be obtained in sufficient 
quantities and will the price admit of its use? 
One prominent veterinarian thinks that even if successful
