RaneidiaY Ia Butter.

Raneidity Ia Butter.
n butterfat is sealed up and kept
Ia . cold dark place It will retain its
normal character and appearance for
many months, but II Il b kept in .
warm place and exposed to light and
air it win quickly undergo chemical
and physical changes and become
rancid. Ransidity is developed by
oxidation. by which means it loses its
customary appearance and smell.
The acidity does not greatly increase
a5 is shown by analysis. There Is .
difference between whole butter and
pure butter fat In their becoming
rancid. The rancidity OF the former
is caused largely by bacteria working
on the casein, actose and other H.
gradients that serve Is bacterial food.
But In the case of pure butter fat
there is no bacterial development for
the reason that thfs substance viii
not sustain bacterial life. Two Euro.
peaa Observation-Disclosures and Rit.
sert-have proven that bacteria can.
not thrive in q medium of pure fat.
and that all changes taking place in
fats are due to oxidation. Air, light
and warmth are therefore the great
factors in producing the fARGfdity of
pure butter-fat. When pure butter-fat
begins to get rancid it begins to
change colcs, getting lighter. This
action begins on the surface and
spreads downward very gradually till
the whole lump is bleached. With
this change comes . lardy smell and
taste. The taste at first acid becomes
burning and pungent. After several
months of such exposure the butter
fat changes into q semi-solid pasty
mass.
Notice Worth Needing
DR.. Reynolds, the commissioner Of
Health for Chicago, 10 sending out tho
following notice, which is being
posted at all stations 1t which MIX
for Chicago Is being shipped: MIX
cans must be clean inside and out.
No matter how clean I can looks. BE-
fore using II should be washed with
soap suds, rinsed with clean water
and then scalded. Milk shipped In
dirty cans is liable to ccnhscation." !"
The notice is not meant to merely
scare people into being clean. 1t has
already been backed up by acts, and
In number of cases milk arriving at
the Chicago depots has been seized
and poured into the sewers. This
should be the fate Of ali dirty milk.
Just rs long as the consumers will
buy and use dirty milk there are men
that will make milk In IN uncleauly
manner and deliver & in dirty cans.
A man that will use dirty can m the
delivery OF milk is altogether likely
to be careless in its production. while
the man that is scrupulously clean
about the delivery of milk is very
likely to be equally clean in his
methods OF production. The Chicago
ohcer that pours a can of dirty milk
into the gutter is doing q service to
the consumer and to the cleanly pro-
ducer of milk in the country.
A Loss to 0airyino.
We are sorry to learn that Professor
d. H. Otis of the Kansas Agricultural
College has resigned his position
there to accept . betterpaying one
as manager OF a ranch ut Oswego.
Kansas. His salary there is to be
81. 400 per annum. with free house
rent and several other things thrown
in. A few of our colleges are paying
exceedingly low salaries and are un.
able to hold any man that proves him.
self of value. A number CT our col
leges are paying fair salaries and are
holding their expert agriculturtsts,
but others do not seem to realize the
value of a live man like Professor
Otis. During the last two years we
have seen quite q number of men
leave their positions with colleges and
60 into commercial life, because In
their former positions they could not
make living. We are not suggest.
ing that high salaries be paid, but
that fair salaries be the order Of the
day in our agricultural colleges and
| experiment stations. We cannot af.
ford to lose men like Professor Otis.
We doubt il this gentleman is permit.
ted to remain very long on the ranch.
Kerosene on Pools.
The Inhabitants of some parts Of
rural New Jersey heard that the best
way to get rid of mosquitoes was to
put kerosene on all the pools and
ponds. Some of them were so jealous
in the movement that they kerosened
the ponds in the COW pastures. One
COW feeding in such q pasture died
In great agony and . post-mortem ex
| animation was held over her. Hel
stomach revealed the cause of hel
death. which was kerosene. The farm
er examined his pasture and found
the water covered with the deadly oil
The other cows were taken from the
pasture before they had time to drink
| of the water. This should act as q
caution to the people engaged in the
laudable work Of mosquito destruc
tion. Water that animals are likely
/ to drink should never lie made the
subject Of this treatment. We think
the farmers living near towns and vii
lagos will have to be more and more
on the lookout for this treatment ol
their pastures. especially IL the said
pastures happen to have in them
| atagnant pools of water.
