M. V. BYERS. 
and upon post-mortem examination I found the characteristic 
symptoms of black-leg, which are too well known to the profes¬ 
sion to give here. In order to be doubly sure of my diagnosis 
I procured some of the diseased tissue and sent it to Dr. Jones, 
of Rising City, for microscopic examination and received an an¬ 
swer confirming my diagnosis. This herd consisted of about 
150 head. I advised vaccination. The owner had never heard 
of such a thing, so it was impossible to convince him. He said 
that if it was nothing worse than black-leg he could cure them; 
so I said, “ Go ahead.” I do not know what his treatment con¬ 
sisted of, but I do know he lost about 22 head of nice steers. 
They kept on dying all winter. 
The next herd was about two miles from the first, and I will 
say the owner was a more sensible man to deal with. He had 
lost several head. We vaccinated 97 head with first lymph. I 
will say right here that I have used the double vaccine alto¬ 
gether and think it best. Three died between first and second 
vaccination; six or eight weeks after the second, two died; 
none from that time up to this. 
Second herd of heifers of 57, two died before vaccination ; 
none during intervals ; and none after that. Next herd of 354 
head, 12 died prior to vaccination ; none during interval ; one 
after complete vaccination. I also vaccinated several smaller 
herds with no deaths after vaccination. I have always used 
the Pasteur vaccine, but there may be others just as good. 
It will be seen from the above that there were only 3 deaths 
after complete vaccination out of nearly 600 head, and the dis¬ 
ease actually existed in all of those herds prior to vaccination. 
Some would ask how many can be vaccinated in a day. I 
will say that that depends upon the surroundings and the help 
you have. I vaccinated 354 in less than ten hours, and others 
can do equally as well if they have the proper assistance. 
There are three modes of vaccination : The ear, shoulder and 
tail. I prefer the latter for several reasons. 
I will further state that it is generally believed cattle will 
not contract the disease after three vears of age. I will relate
