Milk" Fever.
Heavy milking cows uru often af
fected with tnllk fever soon after calv
ing. Tbe llrst symptoms appear from
ten to twenty hours after, calving. The
cow becomes uneasy, ceases to eat or
to notice the culf and seems to be In
considerable pain. The wall: Is un
steady, and the animal soon falls and
Is unable to rise. If not attended to,
death Is very likely to result.
The cause of milk fever is not def
initely known. Since It occurs only In
heavy milkers It may be due to part of
the milk being reabsorbed again and
acting as a poison to the nerves. Light
feeding for a week before and after
parturition is good preventive treat
ment. One to two pounds of epsom
salts given a few days prior to calving
will reduce the liability to the disease.
When the udder is greatly enlarged
previous to calving it is well to milk it
out.
The most effective remedy for milk
fever is what Is known as the air treat
ment. This consists in pumping the
udder full of air, one quarter at a
time, and working it well to get the
air into all parts. A common bicycle
pump may be used if a regular milk
fever outfit is not at band. Both the
udder and tbe instrument should be
disinfected before the treatment is
given.
Hog Cholera.
Hog cholera and tbe closely allied
disease, swine plague, are tbe greatest
sources of loss In the swlue industry.
The first symptom is a refusal to eat.
There are red and purple blotches on
the skin and a sticky discbarge from
the eyes. Tbe walk is often unsteady,
and there is more or less coughing.
There is no internal treatment that
will cure hog cholera. The best means
of handling it is by prevention. Dogs,
crows and pigeons carry infection from
one herd to another and should be
kept away with a shotgun if neces
sary. Running streams also carry In
fection. When there Is cholera In the
neighborhood no one but the regular
feeder Bhould be allowed In the hog
lot. The pens should be disinfected
frequently with whitewash or coal tar
dip. Having the hogs divided into
omall lots helps to keep the disease
from taking the whole herd if it once
gets a start. All hogs that die should
bo buried at once. When new animals
are brought on to the farm they should
be kept In quarantine for at least a
week.
A system of vaccination ha? been de
veloped recently ot is proving very
successful.
The sixtli article of this series, "Pas-
turcs and I'onige," begins next week'
Profit From Animals
This question is often discussed and
frequently but to little purpose. The

fact that lie lias grasped only a part
of the subject.
Ordinarily the cow will prove most
profitable uuder intensive conditions
of farming, as nntri nts are furnished
in tlio form of milk much mom cheap
ly than in the form of hoof. But it is
possiblo to grow mutton oortain

farmintr, virtually without any cost.
The rf ference is to a small band of

By an oversight of somobody, owing
nerhaD to the excitement of Christ
mas time, last week's items were not
sent to the Connor office in time ior
publication, but we will try to do a
little better this week.
The weather continues to bo clear
and cool, the mercury hovering around
tlio freezing point and occasionally
venturing a little, below.
Potato nigging is at a standstill and
men do but lif's exoopt to keop
warm by the fire.
B. F. Weddlo, our genial neighbor,
improved the time by getting married.
The bride is a very estimable lady,
whose farm lies across the road
from his, wliioh will make it very
convenient to work both places. They
gave us all, the surprise of our lives
when they went, to Oregon City laBt
Wednesday and were quietly mar
ried. The neighbor met them nrst
on Saturday evening at. the sohool en
tertainment and Christmas tree.
where thev reoeived many and vari
ous presents from tho tree and many
a friendly handshake from friendc of
both. After all was over, the noys.
having come proparod, went down
and gave them a charivari, in which
the girls heartily joined.
The scliool entertainment was ex
cellent, the scholars wero drilled to
perfection, but the noise aim distur
bance and loud whispers and even
talk in the baok of tho room marred
the pleasure of those who o me to
hear and enjoy. One baby with a
whistle which he would put to his
mouth with botii hands and screech
through, and stamp his big boots on
the floor, seomed to try to lead all
the rest. The querv is, "Why don't
his mother keen him at home if he
don't want to hear anything himself ?"
There was another wedding anrt
charivari in the neighborhood Inst
week, when Mr. Wilkins daughter
married a young man from Newberg,
and it is said the crowd scattered
giant powder over the fields, and Mr.
Wilkins would like to hire a man to
do the first plowing, though
it is suggestod that he may sow turnip
seed, and whon ready to gather cover
with straw, set it anre, aiid loi his
turuips would be pulled without
trouble.
Christmas passod otl pleasantly. A
tree at the school house Christmas
eve, one at the church Christmas
night and about every family had
tlioir private ho.uo tri e to please the
children, and ah hough the chimneys
aud stovopipes of tins later day
puzzle their little heads not a little,
thoir stockings are mystoriously found
111 loi in the morning even it nuug
from the backs ot chairs.
J. Q. Gage aud family from St.
Helena are Bponding the holidays at
the old homo and riding about tlio
neighborhood calling npou old neigh

A real estate agent was about last
week. Ho stayed over night with
Mr. Powell, who listed his place with
him, we hoar, for $4f00.
Deau J. A. Boxell of the school ot
Commerce of the Oregon Agricultural
College has published a bulletin on
"Farm Mothods for the Farm" which
is attracting widespread and very fa
vorable comment from practical farm

bulletin presents in a cloar and simple
manner systems of bookkeeping and
accounting Jwhioh enablo the farmer
to koep definite and helpful reoord of
his business. It ineets a long felt
need in farm management. The
