will quickly burrow. A dose of Epsom salts to which is added a
small quantity of spirit of nitre should be given, as the pig affected
will almost invariably refuse food for a time. Neat's foot or sweet oil
applied to the spots will relieve the irritation.

RICKETS

This is not by any means a common ailment amongst pigs, but it is very
hereditary. The most common cause is too close breeding. The bones and
joints appear to be unequal to the performance of their duties, the pig
staggers and stumbles when it attempts to move, whilst sometimes the
back is affected, when the pig is stated to be suffering from
"swayback." As a rule treatment is inadvisable as recovery is doubtful.
The first loss by knocking the pig on the head is generally the least.

TUBERCULOSIS

Pigs, like unto human beings, are much subject to tuberculosis when they
are kept under conditions similar to those which result in human beings
becoming affected. The disease is highly infectious, pigs coming in
contact with or even being housed in sties where pigs affected have been
recently kept are very likely to become infected. Some persons declare
that tuberculosis, or, as it is more commonly called, consumption, is
hereditary. For this there does not appear to be any foundation. The
chief thing to prevent one's animals being affected is to keep them away
from contagion. Although many parts of the body may be attacked by
tuberculosis, the lungs are more frequently affected than any other of
the organs, owing probably to the ease with which infection by the
minute germ is conveyed to the lungs in the act of breathing.

In the past a considerable number of pigs became infected through being
fed on skim milk which contained germs from the udder of a cow suffering
from a tuberculous udder. In these cases of the lungs and the bowels
becoming tubercular, the pigs become unthrifty and frequently waste away
and die. When the bones and other portions of the body are attacked the
development of the disease is not so rapid, but in any case the wisest
plan is to destroy the animal and thoroughly disinfect the place in
which it has been kept. Save when the disease is local and of very
limited duration the meat of a pig suffering from tuberculosis is unfit
for human consumption.

WORMS

Pigs are subject to various kinds of worms. Of these the most serious by
far is the worm which causes the disease called Trichinosis in man. The
worms are transmitted to man i
