COUNCIL BRIEFS
Police Chief Lloyd Westlake
has advised local garagemen, that
if they are called to tow vehicles
from an accident scene, they are
responsible for removing broken
glass and other debris from the
roadway.
Mayor Donald Symons told
Town Council this week that the
provincial police already have
such a requirement.

tender of $475 for painting in
the Clinton Fire Hall and was
given the job Monday by Town
Council. Tbe only other tender,
$492.50, was received from D.
A. Kay and Son.

Councillor Cameron Proctor
complained this week about
noise from snowmobile engines
late at night. "Can anyone tell
me, he asked, why they run
around at 3:30 a,m.?
"Does it take that long for
them (the operators) to get
sufficient interior insulation to
take the cold . . . enough
antifreeze?"
He said the snowmobiles
make a "terrible racket" on back
streets and added that some
drivers don't use the best
judgment and are prompting
complaints that they cross
private property without
permission.
Councillor Gord Lawson said
Grain virus problem
being studied anew
OTTAWA, January 10, 1968
— 'Scientists here are taking a
new look at an old virus problem
— barley yellow dwarf.
The virus, which is
Canada -wide, causes yield losses
in oats, barley and wheat. The
sj r'hptbms are severe stunting of,::
plants, reddening or yellowing
and ultimate death of leaves,
reduced seed set and shrivelled
seed. •
The present approach is a
study of the virus in aphids. Dr.
Yogesh Paliwal of the Canada
Department of Agriculture's Cell
Biology Research Institute hopes
ao cuscover now aphids acquire
and transmit the virus. They
pick it up while feeding on a
diseased plant, then they
continue to transmit the virus to
other plants for as long as they
live.
"In about 12 to 24 hours of
feeding on a diseased plant, a
large proportion of the aphids
can acquire virus and become
infective for their entire
lifetime," Dr. Paliwal says. "We
know that they can continue to
infect plants, but we want to
,know how."
The study is a difficult one
because these aphids, when they
are full grown, are only about
twice the size 'of a pin head.
These lice -like insects feed on
plants by spearing cells with
their needle-like mouth organs,
then sucking out plant sap.
Dr. Paliwal is rearing aphids
and placing them on infected
plants. Then he slices them into
thin sections like a loaf of bread
in a microtome, and examines
the sections in an electron
microscope to locate the virus in
the internal organs of the aphids.
"We want to know where the
reservoirs of virus are building
up inside the aphids," Dr.
Paliwal says. "When we discover
the locations, we will probably
know more about how the virus
is spread."
He has also made an
antiserum for this virus by
taking the virus from infected
plants and injecting it into
rabbits. Ile hopes to use the
antiserum produced by the
rabbits as an additional research
tool to trace the development of
virus inside the body of aphid
vectors.
Dr. Paliwal has similar work
underway with tomato spotted
wilt virus, which occurs from
coast to coast, The disease,
which is transmitted by onion
thrips Small lice -like insects
less than 1/6th of an inch long
* can kill tomatoes and tobacco
and infects a number of
flowering plants
Only the young onion thtips
can pick up the virus from an
infected plant and these nymphs
Must iricubate the virus for eight
to 12 dVS before they can pass
it on t6' healthy plants. Some
cart continue to ttanst'nit virus
for their lifetime._ This makes
them even more fascinating to
study because we want to 1tnoW
why only nymphs can acquire
the virus and what happens to
the virus inside the thrips before
it is transmitted to plants.
Dr. Paliwal recently
completed similar studies with
wheat curl mites, which are
worm -like insects ..about .1/1OOth
of an inch long and are
responsible for the spread of
wheat streak mosaic virus which
attacks wheat in southern.
Alberta and wheat and corn in
southwestern Ontario. This
work, also done with the help of
the electron microscope, showed
that the mites built up a pool of
wheat streak mosaic virus in a
part of their intestines.
"We think that the virus from
its reservoir in the hind intestine
of the mites often flows back to
mouth " parts while the mite
moves forward and is put into
the plant cells while feeding,
Also the virus may be extracted
in feces and smeared over the
rnite-feeding punctures on the
leaf surface, resulting in a plant
infection through these
punctured cells."
Dr. Paliwal is trying to find
out if this reservoir of virus
results from multiplication of
the virus in the mite body or if it
results from accumulation of
virus as the mites feed on
diseased plants.
It is important to know the
relationship between viruses and
their vectors, including
knowledge about transmission.
This knowledge helps to
formulate better control
methods against the insect
vectors, Dr. Paliwal Says.
"The type of relationship
between a vector -virus system,
especially the length of
persistence of virus in the vector,
also has an important bearing on
cultural control methods.
These controls could include
changing the seeding and
harvesting dates, selection of
early or Iater-maturing varieties
of crops and eradication of
over -wintering hosts of vectors
and viruses. These control
Methods would either avoid or
cut down the exposure of the
crop to vector populations.
There is also the possibility that
the vectors could be controlled
by sprays. Farmers would need
to know when the vectors are
capable of spreading a virus and
how long they will retain this
ability in order to make accurate
decisions On when to spray for
most effective control.
"Viruses are fascinating to
study," Dr. PaliWat Says,
"particularly the ones
transmitted by vectors of
microscopic size, We know very
little about their relationships to
their vectors, but with mote of
this type of work, which is
difficult and challenging because
Of the microscopic size of the
vectors, we will learn More
about thete 'fascinating systems.
Some day we hope to learn how
to Stop the crop losses" they
cause."

Douglas Thorndike and Don
Kay have been reappointed to
the Clinton Cemetery Board for
three-year terms,
Town Council approved the
appointments Monday night and
named Councillor Norman
Livermore a member of the
board for one year.
School board
meets Saturday
Weather conditions forced
the Huron County Board of
Education to postpone its
interview of applicants for the
job of business administrator last
Saturday.
The board plans to screen the
applicants at a meeting this
Saturday at the courthouse in
Goderich. The next regular
'meeting of the board is to be
held Monday night in Seaforth
and it is believed a business
administrator will be chosen by
then.
The county board received 31
applications for the . post and
studied the resumes at its last
meeting, held in Clinton,
January 6.
Get free permits
for snowmobiles
in national
parks
Opportunities for interesting
motor -toboggan trips in most
national parks and greater
control of their use are provided
for in a new policy directive
recently issued to Park
Superintendents by the
Department of Indian Affairs
and Northern Development,
The purpose of the directive
is, • to ,,encourage safe use of
oversnow vehicles and to ensure
that wildlife and forest growth
are protected. The rights and
pleasures of trail skiers and
snowshoers must also be
safeguarded.
For the 1968-69 winter
season, a free permit will be
required to operate a motor
toboggan in the parks. Next
year, however, it is expected
that there will be a charge. The
vehicles must be equipped with a
stock muffler in good condition.
On entering a park, operators
will be informed which trails can
be used and how approved trails
are marked. The trails will be
supervised and some may have
to be closed temporarily if they
become too worn or dangerous.
They will be laid out so as to
make use of existing roads, horse
and hiking trails wherever
possible. They will not follow
nature and interpretive trails.
Temporary winter parking lots
to accommodate cars, trucks and
trailers will be provided
wherever possible.
The new directive advises
park superintendents to develop
a number of short trails and
small areas for day trips and
general use. These will be rated
as class 1 and will not require
special registration and survival
equipment. The longer
cross-country trails and more
remote areas, where overnight
camping is permitted or where
there is greater risk of accident,
will be designated as class 2.
Travel in these areas will require
special registration permits and
survival equipment. At least two
vehicles must travel together on
the long trails. Campsites will be
marked along these 'routes,
making use of existing
catnpgrounds where possible.
The directive warns that
oversnow vehicle trails must not
encroach on developed ski areas,
or coincide to any extent with
trails used for cross.'country
Skiing or other forms of quiet
enjoyment. Also they must not
pass through the winter feeding
grounds of wildlife.
Towing of skiers is permitted
in certain areas, but rallies, Aires,
and endurance meets, or other
organised competitive events
Will not be allowed.
When traversing large lakes in
winter on snow -mobiles always
