Fortunately there is in the human
skin substance called ergosterol
which is changed into vitamin D on
exposure to ultra violet light. So the
person who gets out into the sunlight
long enough generates his own vltamin

the baby. City people usually are not
exposed to sunlight enough to get an
adequate supply and must get this
food essential from other sources. such
as the flSh-liver oils, eggs, salmon and
butter.

Dental health for life is largely de-
termined by the time child is 6, so
that for his first years an adequate
supply of milk or green vegetables and
vitamin D is doubly necessary. A re-
cent report concerning the teeth OF
United States Navy recruits showed
the dental health Of rural recruits
considerably better than that Of urban
recruits. The belief was that both
diet and sunlight had been important
factors in the contrast.
mot only is it essential that child
have an adequate supply Of milk,
but also that the milk should be
wholesome. Yet large proportion of
the small towns and villages of the
United States have no efficient milk
inspection or control, according to O.
E Reed, chief of the Bureau of Dairy
Industry.
Not all large cities even have ade-
quate inspection. But the United
States Public Health Service milk
are being adopted by more and more
communities. This ordinance is really
an outline of the standards necessary
for sanitary milk supply, and d

effect United States officials may be
invited in to check the city's supply
of milk and report to the city officials
their findings, but have no power to
do more. The 676 cities having the
ordinance utilize the Federal Govern
ment service, however, to find whether
or not their milk measures up to the
90 per cent pure standard considered
the minimum for city health.
THE Federal Public Health Service
believes that all milk should be pas

for this process kills all disease germs

preferred: Proper pasteurization raises
raw milk one grade; grade B raw milk,
for instance, becomes grade A.
"Pasteuriza ton, it is true, destroys
most Of vitamin C along with the

this loss, especially since tomatoes or

"CERTIFIED milk is raw milk which
has measured up to the high
standards of the American Association
of Medical Milk Commissions. The
fact that milk has been pasteurized or
certified doesn't mean that it needs
no further care 1t must still be kept
clean, covered and cold.
Dried whole milk is better than
questionable raw milk. 1t has the
advantage of having most of or all OF
raw milk's original vitamin, but is
not always available Where dried
