ground, burrow into it short dis
lance and pass through pupal
stage.
After a few weeks they emerge
from the ground as adult flies. When
the infestation by these grubs Is
light the only damage is through IT,
ritation of the nasal passages, but
when the infestation Is heavy there
Is a profuse nasal discharge, difficult
breathing and loss of appetite. This
condition may result in loss Of flesh,
weakness and finally death.
Treatment for this parasite Is not
practical. In case of high-priced,
pure-bred animals, treatment might
be justified, but should only be I'M
dertaken by an experienced veter-
marian, as treatment consists Of
trephining (boring through the bones
Of the face) and removing the grubs
with instruments.
Preventative measures are the
more practical. These consist Of
smearing the noses Of the sheep
with pine tar. "A convenient meth
cd Is one by which the sheep apply
the tar themselvse. This is accom-
plished by boring two-inch holes
about six or eight inches apart in
a log, putting salt in the holes and
smearing tar around the holes. The
holes should be deep enough and the
salt kept at the proper depth so the
sheep will come in contact with the
tar when they eat the sat. BY this
method the nose VIII be smeared
with tar and the flies repealed.
The sheep tick is more or less
prevalent wherever sheep are found.
It lives in the wool and on the skin
and does damage in two ways: First,
by being a blood sucker, causes
much irritation, loss Of blood and
general debility; second. it Injuries
the wool by soiling it with its ex-
creta and by depositing the young
pupae (nits) in the wool. An infes-
tation with ticks may be suspected
when the sheep are noticed to bite
and rub themselves, pulling out the
wool, causing a ragged-looking
fleece. The ticks may be easily
found by parting the wool and max
ing search for them.
Treatment consists of dipping in
any of the standard dips, either coal
tar creosote, cresol, lime and sui.
phur, or nicotine and sulphur.
'Arsenical dips will kill the ticks, but
they are not desirable for sheep. The
dipping should be repeated in from
twenty-four to twenty-eight days.
To prevent infesting clean hocks
or re.nfesting dipped fiocks, al,
places which have been occupied by
ticky sheep should be thoroughly
cleaned and disinfected.
Care should be taken to remove
all bits of wool, as these may contain
the "nits" which are quite resistant
to common disinfectants, though any
adult ticks that may remain in the
pens will likely be killed by a thor
ough application of the coal tar or
creol-n dips. ALI manure and litter

Pens that have contained ticky
sheep are cons dered dangerous for
clean sheep for period of two
months, unless thoroughly clean~d
and disinfected. Clean sheep should
not be allowed to mingle with cky
sheep. Goats may carry sheep tick
and even p -ople may harbor ticks in
their clothing for a short time and
ca ry them from one flock to anoth-
err. The latter is especially true at
sheep-shear .ng time.
The screw worm is the maggot of
a species of blow fly. This fly de-
posits it's eggs in dead carcasses or
in wounds in live sheep.
These eggs hatch quickly and the
.maggots burrow into the wounds
and grow rapidly.
The best treatment for Infested
wounds is chloroform. Pour the
chloroform into the wound, after a
little while remove the maggots AMI
wash the wound with some mild
disinfectant. Then smear with
pine tar to prevent future attacks
of the fly.
If care is taken to protect all
not attack them.
All carcasses should be burned or
deeply buried to destroy the breed
ing places of the flies.
Sheep wool maggots are similar to
the screw worm and are Matched
from the eggs of blow flies resem-
bling to some extent the screwworm
fly. These flies deposit their eggs in
tail and buttocks.
When the wool about the tail be-
comes soiled from arrhea, it
should be clipped off or washed clean
SO that the flies will not be SO read.
lily attracted.
Eyes at lambing time are some
times annoyed by maggots. It is
advisable to breed the ewes for early
Landing so they will escape the
blowf1y season. It has been recon-
mended that the tail region of the
ewes be sprayed with a .02 per cent
solution Of arsenious oxide shortly
before Landing time.
Infested sheep may be treated by
clipping the wool from the affected
parts and applying chloroform, con-
centrated dip, or a mixture Of tur-
'a"rtine and pine tar.

wounds are often caused by accumu-

The foot may be cut by sharp stubs
