that is run a fair distance daily. The
dirty oil should be drained off, and the
crank chamber plugs replaced, then
plenty of kerosene should be poured in
the engine, which should be started
UP and run for one minute. The ker-
osene should then be drained off and
fresh oil put in the base chamber.
When travelling over roads where
there is not much traffic, advantage
should be taken of the opportunity
thus afforded for scavenging out the
cylinders. This is very easily and eff
fe tually done by closing the throttle
on down grades and perm itting the
car to coast while pure air is drawn
into the cylinders. This cOols and
cleans them at the same time. besides,
in the modern type of cars, providing
a slight economy in fuel. The eager
rush of the motor after the scaveng-
ing period is sufficient proof in itself
that IL is q beneficial practice.
In replenishing the radiator it is al
ways advisable to fill it slightly above
the vent or overflow, so that you can
be absolutely sure that the vent pipe
is not choked If the vent pipe be
allowed to become completely blocked
it is bad for most radiators, as an ac-
emulation OF steam, which is very
general when climbing long hills on
certain pressure above atmosphere
on it, so that if there are any weak
places the radiator is certain to COM
mence to leak II would hardly seem
probable that the vent pipe should
choke sufficiently to permit any pres
sure to be generated in the radiator
but the fact remains that these vent
pipes do choke in this way if they are
neglected, as certain amount of sed-

and that, combining with grit seems
to make a sort of plug of hard, almost
cement-like nature, which completely
seals the vent. So many radiators are
more or less delicate that the matter
is well worth bearing in mind.
fabrication Trouble and Cure
In cars with direct drive on the
top speed the first motion shaft in the
gear box is made in two parts. and on
the top speed, by means of some form
Of dog clutch; these two parts are
made solid and one rigid shaft. On
the other speeds one portion reVolves
in the end of the other, and this bear
ing is usually pushed either with gun
metal, or, what is better, manganese
bronze. Lubrication is provided by a
hole drilled in the outer shaft and
passing into the bearing, and though
the gear box may be full of grease,
as a result of centrifugal action, the
lubricant is flung away, and thus the
bearing may fire" 1t is a good plan
to use half grease and half oil for the
gear box and to keep it well over the
height of the shaft. Even this bearing
may run dry.
One remedy is to take the lid off the
gear box every day, and with a small
syringe to inject some oil into the
bearing, but this is rather a bother.
To avoid doing this and yet maintain
fabrication a small length of watch
spring can be fixed to the side of the
gear box so that the free end of the
spring presses on the oil hole in the
first motion shaft. Then as this shaft
rotates grease enters this opening, and
as it passes under the spring it can
not be thrown aside, but is pressed
into the place where it is needed. As
the shaft revolves in lubricant, the
pressure of the spring win not cause
enough friction to do any harm.
You can buy It. perhaps at many places. but
there's one BEST place to buy it-and that
