after she has gone dry. Burn the hole with a pointed stick 
of caustic potash, which destroys the fistula, then while it is 
healing the hole disappears and it will be all right the next 
time she calves. 
8. Cow Pox. 
This is often met with and affects herds in all parts of 
the world. It is somewhat similar to smallpox in people only 
it is not nearly so fatal. It is an infectious disease, that is, it 
can be carried from one cow to another. For instance, one 
man is milking eight or ten cows and only one has the disease 
at first ; he will carry the disease to all the others. 
Symptoms. — The cow seems feverish and does not give 
quite so much milk. In a few days, little red, pimple like 
spots appear around the teats. In a day or so more, *:hese red 
spots rise up in the form of blisters, which contain a watery 
fluid. If these are not broken during milking, they dry up 
themselves and form scabs, which, in a few days, drop off, 
leaving the teat natural. It generally takes from eight to ten 
days to run its course ; but sometimes, when the blisters on 
the teats are broken by the milker's hand and kept irritated 
by milking, or flies, they take a long time to heal. 
Treatment. — Keep the cow separate from the others, and 
allow only one person to milk her, and no others, so as to 
keep the disease from spreading. If in the spring, let her 
have grass only. If at any other time of the year, feed sott 
food with boiled flax seed in it, and give the following pow- 
ders for the blood and kidneys: 
Nitrate of Potash or Saltpetre ]4 pound. 
Sulphur % pound. 
Ground Gentian Root % pound. 
Mix thoroughly and give a teaspoonful night and morn- 
ing in a mash. Each time before milking, bathe the teats' 
with lukewarm water and soap, then milk carefully and use 
the following preparation : 
Sweet Oil 4 ounces. 
Carbolic Acid 10 drops. 
Mix and apply to the sore parts each time after milking. 
9. "Drying" a Cow. 
Give her a pound of epsom salts in a quart of lukewarm 
water as a drench. Bathe the bag once a day for a week with 
Lukewarm forge water or warm vinegar. This may be
