Mrs. G. K. We should all
try to cheer him up.
Vera K.-He's just a Gloomy
Gus and nothing will help.
Mr. G. K. We've raised
two children and have two
more at home Bill, our baby,
who's 10, and Jeff, our teen
ager of 15. Their older broth
ers is in the Air Force, and
Vera, our only daughter, is in
training as a nurse. It's Jeff
who has me stymied. He's so
worried about marks that he's
at summer school to raise a
B to an A. He skips meals,
studies constantly, never
smiles I hope he doesn't
break down.
Vera K. Jeff's mopey face
sure spoils the scenery at
home. Bill is solid sunshine,
and the rest of us are pretty
relaxed and flexible. But Jeff
is a bunch of nerves. My moth
er scolds me for kidding him,
because he flies off the handle
at any light talk. Just because
my older brother and I never
got many A s in high school,
Jeff wants all A's and consid
ers anything less a failing
mark. He's wrong but he
won't change.
The Council: Jeff's rigidity
about marks may be a symp
tom of illness. Other kids get
rows of A's, but they're gen
erally happy and reasonable
youngsters. Both Vera and
Mrs. K. might try to under
stand the pressures behind
Jeff's drive for academic dis
tinction. Is this his way of be
ing different from the rest of
the family? We'd strongly
urge at least one consultation
with a psychiatrist so that the
extent of Jeff's obvious de
pression may be gauged. At
the risk of sounding alarmist,
we must cite the high inci
dence of attempted suicide
among youngsters under 17
(102 in one year reported by
Bellevue) from unsuspected
depressions. Certainly the boy
must be brought to the stage
where he can take (and offer)
some friendly joshing. Only,
a fearful, confused kid goes to
pieces at a sister's banter
Adolescents in general are
highly emotional, but Jeff
Fichtner Warns of
Glancing from Road
Acting Police Chief Clyde
Fichtner issued a reminder to
day to all persons who will be
vacationing in August to stop
before starting to enjoy the
scenery.
A vacation can be ruined,
he stated, by inattention on
the highway. The safe way to
see the scenery is to find a
wide shoulder or viewpoint
and pull off the highway.
Even a brief look at high
way speeds can be fatal, Ficht
ner emphasized. At 60 miles
an hour a car moves about 350
feet with every normal breath
of the driver, the officer ex
plained.
Look away to admire the
scenery for just two seconds,"
he added, "and you've trav
eled 175 feet."
The people of Brittany are
of Celtic descent. :
seems dangerously so-in need
of clarification, support, un
derstanding. His family can
help him get it. "I am the
most miserable man living,"
wrote Abraham Lincoln to a
friend. The latter, with others,
remedied that.

Washington-fllPO-An ingeni
ously simple submarine pro
pulsion system invented by
Comdr. Frederick R. Hazelton
Jr. of the office of naval re
search, promises to provide
a key to man's conquest of
the ocean depths.
The "Hazelton propeller" is
only now In the limelight be
cause of more than three
months of fruitless attempts
to locate the nuclear submar
ine Thresher off Cape Cod,
Mass.
The Thresher floundered in
8,400 feet of water which is
a mile and a half down but
substantially less than the 12,
451-foot average depth of the
seas.
Hazelton, a 1945 Annapolis
graduate from Nashville,
Tenn., has been working on
his idea since early 1961. He
has spent nearly $1 million
in Navy funds and expects a
joint patent to be issued soon
An 18-foot-long, $100,000 test
model of ' his submarine is
nearing completion
His Balloon
At present, more than 90
per cent of the ocean's volume
is inaccessible except to re
search vessels like the bath-
yscaph Trieste which operates
on the principle of an atmos
pheric balloon to lower a sol
idly built gondola containing
two or three men.
Though more than 58 feet
long, chiefly because of its
"balloon" containing 30,000
gallons of lighter-than-water
gasoline, the Trieste's spherl
cal gondola is only six feet
in diameter. It has been down
more than seven miles, with
standing pressures of a pound
per square inch for every two
feet of depth.
There are more complicat
ed features of Hazelton's in
vention, but the idea it con-
tains for mastering great
depths can be stated in a few
words and in terms of the
Trieste.
He would place the propul
sion machinery outside the
hull. Then the hull could be
solidly built, with no moving
parts, like the gondola of the
bathyscaph. The structural en
gineers would still have a
great deal of work to do but
there is every reason to think
that under these conditions
the necessary strength for any
depth could be achieved.
Hazelton's submarine would
need no "balloon," because it
would be powered for propul
sion In any direction includ
ing up or down, and a side
ways movement impossible for
present submcrsiblcs
Speed would at least equal
that of present types and prob
ably would become greater
rather than less with depth
because of reduced cavitation
(a partial vacuum in fluid
around a revolving propel
ler.) It is generally accepted
in the Navy that submarines
are rapidly approaching the
day when they will travel
much faster than surface
ships.
The Hazelton submarine
would have no propeller in
the usual sense. Instead it
would have two huge, counter-
revolving rings," placed like
rings on a finger near either
end of a cigar-shaped vessel.
The rings would be driven
by electrical motors which
would draw their power
through solid cables from the
sub's nuclear reactors. The
motors, outside the hull,
would be operating in sea
water a horrible thought in
terms of old - style mainte-1
nance. But Hazelton has word
from the two biggest U.S. elec
trical companies that modern
technology makes this pos-!
sible.
Hazelton told UPI in an in-1
terview that if he gets a go- j
ahead from the Navy his sub
marine could be operational in
six or seven years at depths
about double the present max
imums, which are secret but I
probably not much more than !
1,000 feet.
Solution of the structural
problems for really great
depths might take several
more years. Hazelton said
aluminum and fiberglass at
present look more favorable
than steel because the
strength - to . weight ratio is
greater.
The 18-foot model, under
construction at the Nether
lands ship model basin in
Wageningen, Holland, and due
to arrive in this country next
October, has space for a test
pilot but in the absence of a
nuclear reactor naturally
can't be self-propelling.
It will operate on power
brought by cable from outside
the tanks at the David Taylor
model basin outside Washing
ton. The model's chief func
tion is to test unique hydro
dynamic characteristics.
Mounted on each of the re
volving rings are a dozen or
more short fins which, in a
full-scale submarine would be
two to three feet long and
which vary their pitch with
each revolution. These are ad
justable for propulsion in any
direction.
- The fins also are adjustable
for stationary stability in any
position. In other words, the
submarine could stand up
right in the water to launch
large missiles if this were de
sirable. There would be no
.mechanical obstruction to
launching missiles or torped
oes from either end of the
hull.
Hazelton, who already
speaks of the existing nuclear
subs as conventional types, ex
plained that torpedo tubes,
escape hatches and the like,
containing no moving parts,
do not present the type of
structural problem encounter
ed when hull openings are
necessary for revolving pro
peller shafts.
He was, however, conserva
tive about the depths that
could be reached with present
materials and structural meth
ods. Using steel in a normal-
size submarine, he said, the
"hull fraction"-the fraction
of the weight !n the hull
would become intolerable at
considerably less than 15,000
feet.
The oceans, which the Navy
likes to refer to as "inner
space," go down in many areas
to more than twice that depth
and, in a few deep trenches
in the Pacific, to more than
37,000 feet. It's Hazelton's
guess that, with outer space
being tamed, no one will be
satisfied until submarines can
reach any sea bottom in the
world and re-surface.
