Remote sensing projects
study ponds, rangelands
Two research projects utilizing
remote sensing techniques have
begun at A&M. One study is in
pond ecology and the other is an
analysis of Texas rangelands.
Both projects are assisted by
the Remote Sensing Center.
Dr. W. J. Clark of the Biology
Department is measuring pond
ecology parameters.
He will monitor the physical,
chemical and biological charac
teristics of a series of ponds us
ing aerial photography and a
combination of film and filters.
Dr. Robert H. Haas, assistant
professor of range science, di
rects the rangeland study.

RAIN ALL DAY Tuesday didn’t stop construction on the
campus, even if it did get muddy in the multitude of holes.
Welders continued on the pipe system being put in on the
north side of the Academic Building, and the trench they
were working in, about 10 feet deep, was no exception.

Seat belts with a proven high
failure record are still found in
many private aircraft and com
mercial airlines, an aerospace
engineering major has found.
Vincent C. Anderson of Ma
drid, Spain, reported in a study
for an aerospace engineering
course that no belt is perfect,
but metal-to-metal buckle types
have superior safety features.
“A metal-to-metal buckle simi
lar to that used in military air
craft should be used in private
aircraft,” recommended the stu
dent who recently received his
bachelor of science degree and
commission as an Air Force re
serve officer.
Anderson pointed out that fric
tion belts that fasten metal to
fabric were prohibited in sports
car racing several years ago.
New car installations now rarely
use the friction belt.
Problems with the metal-to-
fabric belt include slipping under
alternating load and release, fre
quent jamming and weakening of
belt fibers “from constant crush
ing and abrasion of serrated
metal. With the metal-to-metal
buckle, there is no such effect,”
he said.
Anderson cited Federal Avia
tion Administration research and
recorded difficulties with the
metal-to-web buckle. In a 1968
single-engine airplane ditching
off the Bahamas, the impact
pulled the belt so tight the pilot
had trouble releasing the buckle.
The Amarillo Palo Duro High
School graduate said in his re
port to Dr. Charles A. Rodenber-
ger that metal-to-metal buckles
can jam, particularly after sub
jected to high loads. Corrosion
may also be a tendency of the
better buckle, but he said ano
dized aluminum and quality con
trol manufactured steel buckles
reduce the problem.
Anderson noted price differ
ences in the two belt types is no
more than $2, in models ranging
from under $3 to over $13 per
belt. He said the added cost for
metal-to-metal buckle types in
a 350-passenger airline plane

Rising fear of pesticides
is panic: food technologist
would be about $700.
Though more complex belt ar
rangements tend not to be used,
Anderson suggested shoulder
harness fastened by latch to the
lap belt buckle should be consid
ered for all private aircraft.
“Research has shown shoulder
harness can reduce serious in
juries by 70 per cent,” the former
Squadron 3 Cadet Corps member
said. “If they were engineered
to be snapped in for take-off and
landing, and released for cruis
ing flight, shoulder straps might
be used more frequently.”
The recent graduate said the
best answer would be inertia reel
type shoulder harness. It allows
pilots and passengers free move

FAST FREE DELIVERY
A nationally known food tech
nologist said here Tuesday that
the fast-rising fear of pesticides
—DDT in particular—is largely
the result of panic button push
ing.
He laid much of the blame on
conservationists, the news media
and opportunistic politicians.
He also criticized the govern
ment and the pesticides industry
for failure to avoid the crisis.
The opinions came from Dr.
Emil M. Mrak, chancellor emeri
tus of the University of Califor
nia at Davis, during the opening
BIG DEAL
iioii imt it is
No matter how you feel about the war in
Vietnam, the fate of this prisoner of war
is a big deal. To his wife and children. To
his parents. To the signatories of the Geneva
Conventions. To all rational people in the
world.
The Red Cross is asking you to consider the
matter of prisoners of war and those who
are missing in action in Asia.
It is not asking you to take a stand on the
war itself. It is asking you to ask Hanoi to
observe the humanitarian provisions of the
Geneva Conventions.
Ask Hanoi to release the names of men it
holds prisoner. Ask them to allow prisoners
to communicate regularly with their fam
ilies. Ask them to repatriate seriously ill
and wounded prisoners. Ask them to allow
a neutral intermediary to inspect places of
detention.
Ask them this in a letter mailed to:

session of the third annual Con
ference on Insect, Plant Disease,
Weed and Brush Control.
Last year, Mrak was chairman
of the Department of Health, Ed
ucation, and Welfare Commission
on Pesticides and Their Relation
ship to Environmental Health.
His Tuesday address was the
second of two given on the A&M
campus.
The big campaign against pest
icides began as a “spin-off” from
the activities and concerns of con
servationists and environmental
ists, the food technologist told the
estimated 250 persons attending
the conference.
“In any event, prejudices did
develop, conservationists became
more active, and as the snowball
grew, industry unfortunately did
nothing to contest the trends or
to improve their situation with re
spect to the environment,” he
pointed out.
Then came the newspapers and
magazine, which Mrak said had a
“field day” covering the pesticides
issue.
“As one publisher said to me,
he desired to give the people what
they wanted to read, and further
more, he had to sell newspapers.
Accordingly, he published what
he thought they wanted and to
sell newspapers. This, of course,
meant printing slanted and dra
matic stories that did no one any
good except the communications
media,” he said.
Politicians moved into the pic
ture, Mrak said, because they
realized the public interest and
publicity value—especially in an
election year. Hearings were held,
bills were introduced, “and away
we went.”
“I’m aware of one legislator
who even indicated that he just
had to have a bill on DDT regard
less of what it meant, said or did.
His objective, of course, was to
obtain publicity, and this he did,”
Mrak said.
The speaker described the agri
cultural and pesticides industry as
scattered and confused. Construc
tive programs are lacking.
“We actually see industry push
ing the panic button in some cases
—even to the extent of ceasing
to manufacture certain chemicals
and discontinuing research in this
area,” he explained.
