Monday night and then sped on past
Callisto Tuesday. Io was examined
Monday morning, after the
spacecraft swept past Jupiter.
The other big moon, Europa, was
examined earlier. The new Callisto
pictures showed a spectacular
ringed crater which Dr. Laurence
Soderblom of the U. S. Geological
Survey said suggests the satellite
has a crustal character very much
different from anything we have
seen.” He speculated that the rings
may have been caused by an icy sur
face unable to stand the impact
stress and collapsed in the ring-like
manner.
The surface was densely cratered,
which indicates great age, he said,
and early differentiation into layers
of rock and ice.
Callisto and Ganymede, both
about the size of Mercury and be
lieved to be half water and half rock,
are vastly different from Io, the
smaller, rockier satellite closer to
Jupiter.
Io s mottled orange, yellow and
white surface has been sculptured
by some kind of erosional processes
which produced complex depres
sions, enormous cliffs, broad plains
and abundant troughs that seem to
have been carved by water. Notably
absent are craters produced by
meteoroid impact.
Ganymede’s brownish-gray sur
face, in contrast, looks peppered
with impact craters. The sharply de
fined craters are surrounded by
white material — possibly relatively
fresh ice — splashed out of the
crust.
Song, comedy
delight audience
By KAY WALLACE
Special to The Battalion
! The hardest success to make is
a remake of a success.
Yet a Bryan-College Station
audience was easily and happily
entertained Tuesday night by
Texas A&M University’s MSG
Town Hall’s stage presentation of
Rodgers and Hammerstein’s
“The Sound of Music” in Rudder
Auditorium.
The musical is based on the
true story of a young woman
training to be a nun who is sent
to be a governtess to the seven
children of an Austrian Naval
captain widower. Through her
singing talents, she is able to win
the hearts of the children, as well
as the captain. Eventually the
captain and the governess fall in
love and marry, but it is the eve
of the Nazi takeover of Austria,
and escape is vital.
In the role of the charming,
but flighty would-be nun, Maria,
Sally Anne Howes (remember
her from Chitty Chitty Bang
Bang fame? She played Truly
Scrumptious to Dick Van Dyke’s
Professor Caractacus Potts) was a
believable songbird.
But her counterpart, Earl
Wrightson as the demanding
widower-father of seven, Captain
Georg von Trapp, left something
to be desired as an alluring
romantic for Howes to fall in love
with. Physically, Wrightson is
older, short, husky and appears
more ready to step into another
role he has played — that of
Tevye in “Fiddler on the Roof.”
But never mind, the von
Trapp children were a delightful
diversion to the underlying ro
mance. In step, smiling, on cue
and unusually audible, they were
a convincing family group. All of
them have acting, singing and
dance backgrounds and hold
numerous stage credits.
Capturing several laughs was
Lois Hunt, as the conniving Elsa
Schraeder, trying to charm the
stalwart Captain into marriage.
And understudy Ted Bouton
playing the role of Max De-
tweiler, an uncle to the von
Trapp children, prompted sev
eral snickers as the line-walking,
make-a-buck Detweiler.
All in all, the performance was
very well received by the audi
ence, which gave standing ova
tions for the cast during the cur
tain call.

von Trapp (Earl Wrightson) whistles for his children in “The

41 Dr Max Costa, assistant professor of medical
pharmocology, checks on the progress of
Htures he uses in tests to determine whether
toietal compounds are cancer-causing. Costa
says the tests are 60 times cheaper than
previous methods used for cancer detection,
and considerably faster.

Cancer test has new use
I By CATHY TERREL
Battalion Reporter
Many metal compounds may
>use cancer, says a Texas A&M
niversity researcher, the first to
tive, many chemicals can cause
cancer if received in high enough
dosage,” Costa said. ” What we
must do is check the possibility that
humans may be getting a high
hat theifPfy a research method using enough dosage of cancer-causing
overmn^J' om a hamster fetus to test for
dd accoiaP () 8 en * c activity of metals and
eirfcompounds.
a pauseJ^| 10u 8h this method has been
partoftH^ ^ or about 20 years, Dr. Max
an assistant professor in med-
:d so r Pharmacology, was the first to
method for testing metals.
Sadat me thod takes less time and
za Pahl 0n y than the way federally spon-
B research determines cancer-
metal compounds without even
being aware of it.”
Costa points out that welders
breathe chromium-rich fumes all
day long, and that chromium is on
the list of proven cancer-causing
metals. “Nobody’s telling them to
wear protective breathing devices,
it’s incredible, Costa said.
Costa collects hamster fetal cejjls
and grows them in cultures, then
sidered confirmation that the metal
induced cancer in the culture.
Costa is working on a book that
will show how to conduct this type of
research.
Although Costa believes the ten
dency to develop cancer is inher
ited, he is worried about the possi
ble exposure to carcinogenic metal
compounds that people may un
knowingly come into contact with
everyday, including the high-nickel
content of dental fillings.
New Jersey
reining in its
antique laws
TRENTON, N.J. — Residents
and visitors of New Jersey, you can
rest easy now — you won’t be break
ing the law anymore by riding your
horse faster than 4 mph across a
sidewalk.
And you won’t have to stick to the
three minutes allowed to unload
passengers from your car in front of
a church.
Gov. Brendan Byrne has a plan to
repeal 138 useless laws and sent a
list of “archaic, unnecessary, dup
licative or inconsistent” measures to
the Legislature for repeal Monday.
Provided Byrne’s proposals are
approved, you no longer will be
breaking the law if you:
— Hitch your horse to a public
lamp post or fire hydrant;
-—Drive a horse-drawn sleigh on a
highway without a sufficient
number of sleigh bells on the har
ness to warn others of your ap
proach;
—Race horses on a highway;
—Refrain from stopping your car
and remain stationary if a horse is
passing you in the opposite direc
tion on a highway;
—Overtake and pass a trolley car;
—Follow a trolley car at a dis
tance of less than 10 feet, and
—Knowingly hinder or delay the
movement of a trolley car through
an intersection.
