THE EXPERTS SAY.

One of the most commonly neg
lected parts of the car. as far as
fabrication goes, is the clutch operat-
ing mechanism. In the case of disc
clutches running In oil the fabrication
of the thrust collar and the lever op-
Grating It is automatic. But with
clutches that do not operate in a bath
Of oil. the thrust collar and lever re-
quire oiIing by hand. The service of
these parts is exacting and frequent
fabrication of the ball thrust bearing
and Of the end of the lever which ac-
tuates It is necessary. Furthermore,
the bearing of the, clutch pedal and
the pins which secure the clutch op-
Grating linkage should be fabricated
frequently.
Steel which has become rusty can
be cleaned by brushing it with a paste
composed as follows: Half an ounce
Of cyanide OF potassium, half an
ounce of CASTLE soap, an ounce of
whiting and water sufficient to form
the paste. The steel should be
washed after the paste has been ap-
Piled. in solution of half an ounce
Of cyanide of potassium In two ounces
of water. On the other hand, rust
may be prevented on steel parts by
applying the following mixture with
brush, just as if it were varnfsh:

Theetread OF the tire protects the
/ interior fabric layers. II the tread is
deeply cut. an opening is provided
through which dirt and water eject
their entrance. Water quickly rots
the fabric. which. being weakened,
blows out from the. interior air pres.
sure. Therefore every little cut in the
casing should be plugged as soon as
1T Is discovered, to maintain the pro-
IectiVe covering over the fabric. Cut
blier is comparatively cheap You
may be patriotic. to the extent of saw
ing few cents worth OF wheat or
meat. but how about saving several
dollars worth of rubber by plugging
in time every tire cut? Buy q Wi.

mending ough to be a form of recrea-
in the casing should be handed over
to a tire shop for repair.
Over in Germany they have had to
gather copper and other metals from
every conceivable source, from the
homes, offices, factories. churches, We
/ hope their supply Is fully exhausted
but then we must not be wasteful OF
our own just because there is a
plentiful supply. We must conserve
the supply of every metal brass, cop
per. aluminium, steel Spark plus
shells. brass and copper parts on tht
car, lead parts. etc. should not have
to be replaced sprematurely Take
your storage battery and consider
that the sulphurfc acid and the lead
used in it are war materials. The
average life of your battery is twelv,
months. Think of how much you will
be doing for yourself and your coun.
try If you extend that to eighteer
months. You can do 1t If you will
try. Test the battery with the hydro.
meter weekly in summer and see
that the gravity is around 1900, use
distilled water to bring the cells e
level. keep the battery well fastened
down, the connections tight and clean
Saving current is saving money.
