develop on the grass and stagnant water. The
larvae are again taken up either in the drinking water or in eating
grass or hay gathered on low marshy soil. Warm wet weather favors their
development.

SYMPTOMS: This worm is liable to attack a number of animals at the same
time. The weakest sheep and young lambs are the first to show signs by
coughing forcibly, distressing, hacking and convulsive in character. A
stringy mucus is sometimes expelled during the spasm of coughing. This
mucus contains worms which can be detected, or their ova observed under
a magnifying glass. In the latter stages of the disease, they cough
severely at night. These attacks have a sub-acute character and prove
very exhausting. The parasite by becoming entwined in balls severely
affects the animal's breathing which is always remarkably labored in the
latter stages of the disease. The animal refuses to eat, becomes
emaciated, anemic, mucous membranes of the eyes, mouth and nose become
very pale and the sheep die in convulsions from suffocation.

PREVENTIVE TREATMENT: Avoid grazing your sheep on low marshy soil,
especially during warm wet weather. Young lambs and weak ewes are
especially susceptible to this disease.

MEDICAL TREATMENT: The writer has tried various treatments as fumigation
with different substances and injection of remedies into the windpipe by
the use of a hypodermic syringe, etc., but none have proven very
successful, from a practical standpoint. I would recommend placing the
affected animals in a tightly closed barn or shed, in the center of
which place a pan of red hot coals and cover with Sulphur.

A person should remain in the barn or shed as long as he possibly can
and after the fumes become so irritating that he cannot endure them any
longer, he should immediately make his exit. The sheep should be
compelled to stay a minute or two longer and then quickly open the doors
and windows. Repeat this treatment once or twice a week. Feed affected
animals well. Give them fresh water to drink and protect them from
exposure. This treatment, as above described, has given very good
results, providing the parasites were not too numerous.

SCAB

(Mange)

CAUSE: The mange mite (Psoroptes Communis). This parasite is equipped
with stylets which pierce the skin at the seat where the mange mite
penetrates the skin, and produces small red spots followed by a blister
filled with serum, which ruptures, the serum drying and forming a s
