To Your Health
There Are
All Kinds
Of Hernias
By DR. JOSEPH G. MOLNER
Dear Doi-tor Molner: I al
ways thoupnt only men rould
have hernias. My aunt was
operated on for a tumor about
a year ago. Recently on her
check-up the doctor told her
she has a hernia, but not to
worry about it if it does not
give her pain, and that it may
never require surgery. Is that
true? A.H.C.
Certainly it's true.
And, no, hernia is by no
means limited to men.
A hernia ia a weakened place
or gap in some bodily wall, into
which some other organ may
push through, or threaten to do
so.
There are, in fact, all kinds of
hernias, but by and large we
think of a hernia as being one
of the bowel a gap in the ab
dominal wall through which a
portion of the bowel can force
its way.
Men, because of their physi
ology, have some comparatively
weak points in the groin, and it
Is there that a strain or injury
can cause a hernia. Women do
not have these weak points and
hence are little troubled.
Hernias occur elsewhere. An
umbilical hernia is one exam
pie. Another is a hiatal hernia
or flaw in the diaphragm at the
point at which the gullet passes
through.
Still another is called an in
cisional hernia, meaning one
that has developed at or near the
Incision of an operation. This
. type is mentioned in today s let
ter. Often It requires nothing
more tthan simple support, such
as a corset or a girdle.
Some hernias are of scant im
portance; others, if not correct
ed, can hecome intensely dan
gerous. This applies particular
ly to those in the groin. A por
tion of the bowel can be grad
ually forced through the gap
and become "strangulated" it
is pinched off by the small gap
through which it has worked its
way.
When this happens, It is an
emergency of the most dire sort,
and must be relieved without an
instant's delay. That is why so
many doctors urge that hernias
(depending on their location
and extent) be corrected surgi
cally before they seem to the
patient to bo of any great an
noyance. This sort of hernia, in
short, can be easily repaired.
However, if correction is put off
too long, the hernia may be
come strangulated and urgent
measures will ha needed to save
Vhc patient's life. (The strangu
lation is also agonizingly pain
ful.)
Such a complication is much
less likely to occur in an inci
sional hernia, or in a hernia
higher in the abdominal wall.
So your aunt is quite safe in
doing exactly as her doctor sug
gests: Not to worry about it.

Yellowstone: Peerless Park
Andy tends a complete,
20-volume tet of the World '
Book Encylopedia to Melin
da Autrey, age 14, Shaw
nee, Okla. for her question:
How big is Yellowstone
National Park?
The icy crown of Everest,
highest peak in the world, is
about 29,000 feet above the
level of the sea. But these
bare figures are lost in awe
when we see the mighty moun
tain, or even a picture or
movie of its tremendous bulk.
The Pacific, world's largest
ocean, covers an area of al
most 64 million square miles.
But we must voyage across it
to grasp its tremendous scope
and then we realize that the
bald tape-measure figures tell
us very little.
We can estimate the exact
area of Yellowstone National
Park and figure the height of
all its peaks. But when we
visit the place, we leave the
everyday world behind us and
the bare facts of its size are
lost in wonder. Crowded into
this region there is a greater
variety of splendid scenery
and more natural wonders
than any similar area on
earth.
The great park, which be
longs to all of us, is equal in
area to about half the land
area of the Hawaiian Islands
and about three times the
area covered by the small
state of Rhode Island. In plain
figures, our scenic wonder
land has an area of about
3,471 14 square miles but this
is one of very few plain facts
about Yellowstone National
Park the rest is glamor.
A tourist can drive the 150
miles of highway running

Butterflies Depend Upon Their
Gaudy Colors for Surivval
The vivid colors of butterflies are useful
as well as beautiful. Distinctive hues help
some species to survive.
The familiar orange-and-black Monarch
butterflies flitting about on a bright spring
day are a delight to the eye, but a warning
to birds and other predators. Distasteful to
its natural enemies, the Monarch flaunts its
colors to make sure of recognition, the Na
tion Geographic Society says.
Inedible, or "protected," butterflies seem
to know the value of repetition in such "keep
off" signs.
Uneatable species share strikingly similar
patterns, though they may be from widely
different genera and families. The uniform
patterns doubtless simplify the learning proc
ess for predators. If each protected butterfly
had a different pattern, it would be difficult
for most predators to learn them all, and many
butterflies would die before their enemies
mastered the code.
Predators are emphatic in their dislike for
bad-tasting butterflies. The guady llcliconius
crato of tropical America is generally scorned.
A frog that mistakenly snapped an erato
gagged, spat it out, and shook
and forth. A pet monkey picked up an erato,
sniffed the butterfly, made a wry face, dropped
it, and spent several minutes scrubbing at its
hands.
Many edible butterflies mimic protected
species. The Vivcroy, for example, is a tasty
noon. The park bus takes two
days to give you a guided tour
along this route with short
pauses at countless outstand
ing wonders. You can walk or
ride horseback along miles of
trails, stopping to picnic, to
camp or just to gape where
you please.
The roads and trails, the re
gions touched by human hands
take up only one-tenth of the
great park. Nine-tenths of the
region is primeval, left in the
wild state just as it was cre
ated. Our national parks are
set up to preserve the prim
eval qualities of outstanding
regions. For this reason, there
are laws which forbid the de
struction of any native plant
or animal life.
About four-fifths of the park
is covered with native forest,
tall trunks that climb up the
many mountain slopes and
cluster in the rocky gorges.
There are also patches of
grassy meadow, carpeted in
certain seasons wtih colorful
wild flowers. There are prairie
regions, furry with sagebrush
and sometimes decked with
gaudy prairie flowers. There
are gorges, waterfalls, rivers
and lakes. There are dramatic
geysers and hot springs with
colored basins. And the whole

The animals are less timid
than elsewhere because they
seem to sense that here it is
safe for them to let us pause
and admire them.
Million of people, as al
ways, are planning to visit the
biggest and the oldest of our
parks this summer. As a va
cation spot, it has the magic
of restful calm and exciting
beauty. For a family, the best
and least expensive plan is to
camp there on one of the many
areas set aside for this pur
pose. Because of its northern
latitude and high altitude,
the wonderful region is open
for campers only from June
to September just right for
summer vacations.
Andy sends a Hammond's
Library World Atlas to Bill
Morgan, age 10, of Rexdale,
Ontario, for his question:
How much of the world is
under water?
From an orbit high above
the Pacific, our world looks as
if it is completely under wa
ter, for this vast ocean covers
almost half of the globe. The
Atlantic Ocean also covers a
large area of the big globe.
Then there are the Indian and
Arctic Oceans, plus countless
smaller seas.
All these ocean waters are
linked together, making is
lands of the large and small
land areas. Together, the sea
waters cover almost 71 per
cent of the globe. Rivers,
lakes and swampy regions like
the Everglades cover perhaps
another one per cent of the
surface of the earth. So we
can estimate that about 72
per cent of our world is under
water.
morsel for birds, but it copies the unsavory
Monarch's coloring so well that birds usually
ignore it. The chief flaw in the mimicry is a
black line across the Viceroy's hind wing.
Occasionally a speciment is seen without the
stripe, suggesting that it may gradually dis
appear from all Viceroys.
Sometimes only the female imitates an in
edible species. In many regions, the female
African Swallowtail is so unlike the male
that it took careful study to prove the two
sexes were the same species.
In nature's scheme, mimics never should
be as common as their models, for if enough
imitators are caught, the predators would
learn they are edible.
Mimics often fly in the shade where their
slight differences are not obvious.
Many butterflies also copy natural objects,
such as dead leaves, twigs, barks, and rocks.
Varieties of an English moth vary in color to
match the rocks each prefers to alight on.
Tropical butterflies benefit from "flash
coloration." At rest, the insects fold their
hind wings beneath dull front wings. When
disturbed, they take flight, exposing brilliant
rear wings.
Butterfly color may be a factor in court
ship. Entomologist Jocelyn Crane described
in the National Geographic an experiment in
which she painted out the distinctive red
patches on the black wings of an erato. The
paint job turned a popular female into a
scorned wallflower.
