Jl i electrical parlance it is a coil.
K' Yeu can take an oatmeal box, which
JiW cylindrical in 6hane, or an ertlinary
tube like an oatmeal or salt box and the
second is wound around a wnall tube or
a ball which in made te turn en a shaft
Inside one end of the first, we call the
apparatus n varioceupler. The turning
of the ball or smaller coil inside changes
or varies the amount of electric cur-

t U? . . nlreay Kn,ews wnat ,R ' Se thatV a varioceupler. Other
? M1 is. Ahen you buy wire or rope in kinds of cells are reallv varioceunlers in
tneir resuit-s. but we have different
names te indicate and Identify the dif
ferent kind'.
When the second coil is around a
Fmaller tube and draws out of and
pushes inside of the first, we call it n
loose coupler.
Twe honeycomb cells or two basket
or spider-web coils can be used as a
coupler and when they arc hinged at
one. side and open apart and close to
gether like the pages of a book, or draw
apart like an opening fan, they vary
their induction just as a varioceupler
.does.
Hut the illustration shows the type
of coupler that is always meant when
radio fans talk of varioceuplers.
The variemeter consists of two celli,
tee, one revolving inside the ether, but
in this case the two net only act en
each ether through Inducing electric
currents, but they arc actually physi
cally connected. The electric current
gees into and all around -the outside
coil and the wire where it comes out Is
directly connected te the wire going
into the inide coil and the electricity
gees around that one, tee. It is like
taking a long piece of wire and winding
two coils of it and then putting one
coil Inside the ether without cutting
them apart.
If yen took the varioceupler and made
a wire connection from the coming-out
wire of the first cell Inte the geing-ln
wire of the second, you would turn it
into a variemeter.
And, if you reversed the process and
cut the connection between the two celli
of n variemeter, you would make it a
varioceupler.
Se don't forget the cardinal fact
the coupler lias no actual connection
between the coils, the variemeter hai.

Uncommon Sense : Running for the Train
By JOHN BLAKE
THE man who runs for the train
sometimes catches it, and sometimes
gets tangled up with the wheels and
loses interest in subsequent develop
ments. It Is important te catch a train, but
net nearly se important as it Is te cea
tinue in this life with all ene's' limbs
and facial features in the condition they
were when one first saw the light.
It may be gathered from the fore
going that this is an editorial en pro
crastination, which it Is.
New the gentleman who is running
for a train does net leek like a pro pre pro
crastlnater. Yet if he were net a pro pre pro
erabtlnator there would be no need for
him te run for a train.
TTXA
wf
rhenever the conductor notices that
he has a lead of passengers aboard.
One who contemplates a journey has
abundant opportunity te leek nt the
timetables, and te make his plans ac
cordingly. Ne mntter hew busy he may be, if
he really wants te make a particular
train he can de it.
If the le.s of three or four hours
that will elapse before the next train
starts ler the nunc place arc Impor
tant te him, he will de better te be en
hnnd In plenty of time te get himself
and his baggage comfortably disposed
before starting time.
Otherwise lie may slip en the steps
nnd. although he escapes with his life,
de himself mere harm than the less of
that particular train could possibly de.
rpiHE catching of trains was chosen as
J-. the subject of this article because
life Is figuratively just one train after
another.
A great many years age Shakespeare
wrote about the tide of affairs of men
which, taken at the flood, leads en te
fortune. There were no trains ln
Shakespeare's tlmc
OPPORTUNITY, which is net se
rare a visitor as the proverb would
have nn believe, is much like a train
in that if taken deliberately if is an
easy way of going where we want te go.
Try te rush it, nnd it either gets
away altogether or leaves the aspirant
floundering en the platform as it de
parts. CepvrteM. tll$

Did you drive a car
eleven years age?
Every motorist who used te crank his car by hand
and burn his fingers lighting the lamps ought te have
a wholesome respect for batteries, and a specially warm
feeling for the Exide. The first starting and lighting
battery (1911) was an Exide; just as Exide has been
the pioneer in ether industries through the entire his
tory of the storage battery.
This "ancient history" has a distinct bearing en your,
comfort and economy in metering, because the experi
ence of the eldest and largest manufacturers of storage
batteries in the world is built into the Exidemade for
your car. The result is that the Exide gives excep
tional service. Yeu can depend en its eager power day
in and day out longer than you would believe possible
unless you have already owned an Exide.
Check up en these statements with friends who have
Exide Batteries in their cars. Mere cars leave the
factory equipped with Exides than with any ether bat
tery.' Pay a visit te the nearest Exide .Service Station
and get acquainted with the Exide the lengJife battery.
