show sign of lOOsening, or should the
plates themselves be buckled, it is
more than usual for repairers to say
the job is beyond them. Anyway, it
is quite a general idea that it costs
nearly as much to fit new plates as
it does TO purchase fresh accumula-
tors, and so it would if it were neces-
sary to renew all of the plates. But
since it happens in nine cases out Of
ten that 1t IS merely the positive
plates which have gone wrong, and
since further. there are always less
positive plates than negatives (in
cell with three plates two are mega
tive 80 percent therefore in excess OF
the pOsitive), IL stands to reason that
it should not cost nearly as much
TO replace the latter as It would do
TO buy cells complete. Besides the
small proportion of renewal Of ma
teriaI necessary, the actual work in
vOlved is by no means difficult and,
further. the old pOsitives have a GER
tain market value, which viii be al
lowed Tor by many manufacturers OF
accumulatOrs- Let there be any who
have not learned to distinguish a neg
ative from positive plate, it may be
added that the former is of slate gray
color and the latter is a rich chOcO-
late color.
Tt is good practice, when the car is
TO stand for long periods exposed to
the cold, TO cover the hood and radia-
tor with q blanket or laprObe. This
is a preventive from freezing and, by
holding the heat makes the motor
easy TO start.
Cars stored in cold places should
have the water th6roughly drained
from the motor, radiator and pump, if
any is employed. In laying up a car,
do not let it stand on the tires; use
the blocks under the aXles. A better
way, is to remove the tires. store

Again, driving WITH a retarded spark

ton and muller EXPLOSIONS. When
driving upon ordinary roads, streets,
etc, at ordinary speed, the sparkling
throttle should be advanced at least
% of its travel. This is full economy
However, upon pulling hills sand or
mud, as the speed of the engine de-
creases the spark should occur rela-
tive to piston travel, later, or in other
words, the sparkling throttle should
be retarded in relation to the decreas-
ing speed of the engine There are
no set rules for handling the sparkling
throttle Of any make Of car, upon
given road conditions, but the motor
list soon learns that a retardment or
advancement of the spark. as road
conditions may warrant, assist the
engine in its work, increasing car
mileage per gallon of gasoline. and
materially decreasing the possibility
Of Overheating.
Another cause of undue heating. and
one not IS easily overcome is due to
the grease or oil. with which the wa
ter pump drive is fabricated, working
itself throughout the cooling system
and forming an oil film within the
cylinder water jackets, water piping
and radiator; and in view of the fact
that the oils and greases commonly
used on automobiles are principally
Of mineral origin and consequently
non soluble in water the greasy film
continues to grow in thickness. in
