When thore Is a baby m the house
the city mother always looks askance
on the milk which the covered wagon
leaves at her door. There IL always
the possibility-never dreaded by the
farmers wife, who may be said &c
have q speaking intimacy with the
barnyard cows--that IL may have
come from animals afflicted with tu-
berculosis and that II may fill the
bodies Of the children who drink 1t
with the bacilli OF that terrible dis.
ease. OF course, only one COW In
thousands has Tuberculosis, and OF the
hundreds who drink her milk IL may
be that only one Is infec ted, but even
this remote possibility awakens the
tender solicltude OF the mother.
That Is why sterilized milk--or
milk in which the bacilli are de.
stroyed--has been so much talked
about during the last few years. In
the cities, especially where the milk.
man himself does not know whether
his stock Is pure or not, the use OF
steriiized milk has grown to be on
almost absolute necessity for young
children.
There IRE many manufactures
throughout the country which steril-
Ice milk on large scale, but the
very magnitude Of their operations
sometimes works against them. DR..
Ernst, OF Harvard university, says
that In order to be satisfied that milk
IL really free from bacciili he wants
to see to the sterilizing himself. The
ordinary bacillus Of tuberculosis Is q
very cunning little organism and un.
less great care IL used 1t will elude
pursuit and extinction.
Tho process OF sterilization ID
simple. Psychologists have learned
that when milk has been raised to q
temperature OF 167 degrees Fahrcn--
heit and allowed to remain there
twenty minutes the bacilli are killed.
In order to accomplish this q double
boiler IL used, into the inner part OF
which tho milk Is poured. The
water IN the space between the two
boilers Il raised to the proper tenn
peraturo and then allowed to cool
gradually. Unless everything Is kept
clean. however, somo OF tho bacilli
may hide away In the cracks and
come out afterward as lively and
evil disposed as ever.
The housewife may do the work
Just as. we'll herself. An ordinary
oatmeal or custard cooker may be-
used and the milk heated to the
proper temperature OF l67 degrees,
which can be readily regulated by or
ordinary dairy thermometer, costing
only 30 cents. Ordinarily this will
render the milk perfectly safe fol
children TO use.
But II tho COW was badly afYecteJ
with: tuberculosis there Is another
peril not so easily remedied. The fac,
has been pointed out that the Who'll,
eirculatory and secretive systems o.
such animals ore saturated with tub
erculin, the substance thrown OF Of
the life product Of the bacilli. Tn,
germs themselves may be killed b,
heat and the tuberculln still remair
in tho milk. Against this substanc,
cooking. ut least to any ordinary de
gree OF heat, Is Intellectual. Expert
ments made by DR.. Law, OF Cornell
university, show thatltuberculin CO,
DO raised to temperature OF 25'
degrees and maintained there for {
long period without changing IT
character.
This substance II eaten would no
seriously affect an entirely health,
person. but Its operation, where pull
monary consumption or other form
Of tuberculosis 10 present. even In III
lncipient stage, Ii to excite . con
siderable fever and greatly hssteI
the progress Of the disease.
At the best, therefore, sterilization
Ia only q partial defense against In
Jury from. milk taken from animal
affected with tuberculosis. The bes
way to remedy the difficulty 10 to xii
the cows and send them away to
rendering establishment.
