'FIND REAL FRIEND
IN SELF-STARTER
compression flgoro Just as high as they
dare, with tho result that when the car
bon forms, the size of the compression
chamber Is reduced and the pressure is
rahed to such a. degree that It will cause
pre-lgnltlon and Its resultant knock. When
n, manufacturer telli ou that his engine
Is proof against carbon nnd tho knock
ing occasioned thereby, ho Is probably
trying to offset more serious "knocks"
the car Is receiving from disgruntled
users. A friend bf mine has a four-cylinder
engine In one of the later models of a
well-known car df high speed and power.
On several occasions wo havo been out
dlv ,Un .nml neftr the city .and after
about 125 miles wo seemed to atwasa have
trouble with knocking In climbing hllK
On one trip my friend had tho carbon
burned out carefully before starting.
About the time we reached the end of the
journey the engine began to knock on
the hills from the collection of carbon.
On our return to the city he had tho car
bon burned out again, nnd the knock
ceased.
I advised him to raise the cjllndars one
fourth of nn Inch by a fibre gasket tinder
each cj Under canting, thus Increasing the
capacity of the cylinders nnd nnturnlly
lessening the compression.. He also had to
adjust the water connection and raise
the valvo push rods, and a few things of
that sort When I last saw him he had
run tho car 2000 miles since making the
change, and It was just beginning to show
signs of knocking under severe conditions,
Indicating that the cylinders needed to
havo carbon removed.
Where the knock Is caused In thla way
by a slight compression increase It Indi
cates that the manufacturer had put tho
pressure as high as the engine would
stand, and the only way to cure It Is by
raising the cylinders or lowering the pis
tons by having shorter rods east. The
gasket I have described Is the simplest
method.
The chauffeur and the auto owner who
learn this remedy for knocking-, due to
carbon and high compression, wlll.t
saved a tot of worry and be enable (
cure the engine's) Ills, or havo It done at
tho shop. But, son, take It from mev that
carbon naiumulatlon will e-tuse any of
the high-powered engines to knock and
the only way to cure It li to lessen the
compression. Also the only simple way to
tower the compression Is to raite ith
cylinder with a fibre gasket

When the self-starter became a reality
Instead of a dream, the. automobile camo
Into Its own In Its appeal to the. woman
For many years the man of the family
could not permit his wife or daughter to
drive a car by herself when there loomed
up as a possibility, a stalled engine t,r an
Intentional stop which would necessitate
in operation In cranking that was stren
uous enough to satisfy most men and
generally looked upon as a dangerous per
formance for women.
With the crank a thins of memory ex
cept In emergencies nnd the start of the
motor dependent on nothing more difficult
thsn a Btar..p of the foot or the turn of n
twitch the whole) situation changed.
A woman drlvlrfg a motor down Chest
nut street Is no longer a spectnelo that
causes wonder among the pedestrians. Po
cemmonplaco Is tho sight that cvon tho
traffic policemen no longer make excep
tions for Infractions of traffic regulations
' en the part of womon.
IT IS SPOIIT'S BOON.
While a great many women drive their
S- own automobiles In the city, It Is In tho
iuburbs or in touring mat womon uo
most of their own "chauffcurlng." Tho
sporting Instinct In this country Is dis
tinctly not confined to men.
American women are keenly Interested
In sports as are thoso of no o'ther coun
try. And In spite of tho growing uni
versality of the automobile, as a conve
nience, there are many phases of Its ac
tivities that are essentially sporting
propositions. Further, for an American
woman at the wheel of her own car, con
fidant In her skill to handle It under any
circumstances, there Is a spirit of Inde
pendence that has nn especial appeal for
her. Many women who could afford any
number of chauffeurs prefer to drive
thejr cars themselves on this nccount.
Away they go In the morning to lunch
with a friend, with none of tho worry on
their minds as to where James Is to get
his lunch or how ho Is to earn hi wages
while she lingers over tho teacups.
ALSO A CONVENIENCE.
But to the woman of only moderate
Beans tho possibility of driving her own
ear with a minimum of Inconvenience has
proved a boon. I'orhaps her husband
takes caro of the car himself, and they
have no chauffeur. Heretofore In tho
larger number of Instances, vvhllo tho man
of tho family was at his offlco a per
fectly good car was lying Idle in tho gar
age all day awaiting his return before
it could servo those who had Invested In
it, what might have been for them, a
considerable sum of money. Tho new
conditions have altered nil this, and the
icu-startcr am most or it.
Dut there hnvo been many contribut
ing causes. Detachable rims have had a
bearing. One man or woman tops have
contributed their share. And then, of
course, with motor construction on a
high plane, engine trouble, the bugbear of
til women drivers, Is relegated to tho
realm of remote possibility.
When somebody davlsci nn electrical
ear shift that Is gcncrnlly accepted and
adopted the happiness of the woman who
drives her own car will bo complete.
BIG BANKERS BACK
THE CHEVROLET FIRM
Contribute Large Sum for the
Expansipn of the
Great Plant
Bankers and great capitalists are cold
blooded business men, who leavo sentl
went out of their dealings entirely,
when they Invest money In any project
or "back It," na tho saving goes, they
Insist on proof being given that the
business has merit and that tho article
to be manufactured Is ono that Is sure
to meet with public favor. And tho
more they Invest the more they must
ye made to feel that tho business Is ono
free from hazardous risks. Therefore,
bankers and financiers, in this respect,
are the original "men from Missouri"
wno must be ahown.
Therefore, when oh of the greatest
financial Institutions In America backs
a manufacturer for a tremendous
amount the moneyed men who take such
a risk must have carefully and thoroughly
investigated the merits of the article to
marketed and been satlsfKW that it
S. ab0V8 " ordinary. This Is
what has happened In connection with
uie expansion of the Chevrolet Motorcar

mailer mln.la .i, ,-.- i.

The Chevrolet automobile is a car that
n won a warm place. In the hearts

HI a very modest way, the Chevrolet

such an extent that they are In demand

There is a ra rsc in waitin;
too long to order your Cadillac
EACH year; we have urged the public to guard against possible
disappointment.
And each year, ift spite of this warning, many have had to content
themselves with some other car because they could not . get a
Cadillac.
In spite of steady increases in production, the annual Cadillac shortage
is almost a mathematical certainty.
There is every indication that the current season will see that condition
materially emphasized.
There is the steady, stable, year-in-and-year-out CadJJlac demand to be
gin with a very large number who automatically repeat.
And then, there is the large and steadily growing larger clement of
increase in new Cadillac ownership.
This has been strikingly marked ever since the advent of the Cadillac
"Eight."
Thus far its sales have reached the impressive total of more than twenty
one thousand cars, amounting in value to more than forty-seven mil
lions of dollars.
The vogue of the Cadillac Eight has never been perceptibly checked or
challenged by any other car.
True, there may have been, from time to time, cars which in advance
gave promise of comparable charm.
But their appearance served rather to stimulate admiration for the
Cadillac and to emphasize its inimitable qualities.
Cadillac prestige is based on the universal esteem for the soundness of
Cadillac policies and the soundness of Cadillac principles of construc
tion and the feeling that the new Cadillac exemplifies the most
luxurious form of motoring yet evolved.
Cadillac prestige is steadily growing greater the Cadillac demand will
go right on expanding in volume and in enthusiasm.
Therefore, when we urge you to assure yourself of Cadillac delivery, it
is that you may guard against disappointment.
Tf you can secure a Cadillac now, protect yourself, and take it. ,'
If you cannot do better than to arrange for delivery in a month or two,
we urge you to take that precaution.
