Another pracUce which makes a lot ? '"ZZ'Zr "ST; u
(By H. Clifford Brokaw.)
If you do not have a muffler on your ,
" car the copper will get you as a nui
sance and a fine will be assessed next
y, morning.
But your muffler is intended to
muffle the sound of the motor and
not its power. Yet in many cases
there is such a back pressure from the
. muffler that a large percentage of the
power is neutralixed. It is no wonder
that a lot of drivers of trucks ;and
passenger cars want a cut-out on the
exhaust lino. Some of them might
use it for an accelerator. All because
the' muffler is clogged with soot and
perhaps rust.
'" Necessary to Have Cutout
, The muffler never has been popular
and it may be that is why it is so
- neglected snubbed, so to speak. It
was not a part of the early cars,
which chugged and roared through
' the streets until patient folk began
passing ordinances about it Then it
was considered necessary to have a
cut-out to help start or relieve pres
sure ea the hills,. Jtfodern.motors.do
not require this and the cut-out is not
a part of the regular equipment any
longer. Thousands are made and sold,
however, to drivers who would rather
iisa their heels than their heads who
would rather endure1 the noise than

chance of an. occasional fine. Host of
them do net even know that the muf
fler seeds cleaning.
Now, the purpose or the munier is
this: The .exhaust valve opens with
' the burned gas under a pressure of
close to thirty pounds per square inch.
Every otaws what a. commotion
is made when it is exhausted directly
into the air. The muffler was design
ed to. quiet this, make motoring con
versations possible and enable dwell
ers along the highways to live peace
ably. Imagine the roar of the thou
sands of cars and trucks on Fifth
avenue, New York City, aay day, or
' on a traveled highway on Sunday.

It may naturally happen, and I have apparent that it can not be overlooked

The United States bureau, of stand
ards has completed tests of the effect'
of water injection into the cylinders
of engines. The rcfeults arrived at
of trouble for the muffler is .that of
putting kerosene in the cylinders to
cut the carbon. It will clean out the
carbon, true, but' that isn't all; the
carbon is exhausted through' the muf
fler and the small openings are soon
clogged by the greasy deposit Some
drivers have discovered this, and
where there is a cut-out it is opened,

in this way. It does not'wholly obvi
ate the trouble, however, nor excuse
the careless driver from the duty of
giving the muffler the once-over occa
sionally, the same as he does' other
parts of the car.t
Average Driver. Should Know How
Probably one of the chief reasops
for neglect is the fact that the muffler
is a non-moving member, and many
rontons can not see why a thine; that
does no "work" should get out of
whack. But it has to withstand a
rush of heated gases and the-heating
of innumerable fine particles of car-
PROPER TURNING OF CORNERS IN AIT AUTO
ONE OF THE DIFFICULT THINGS TO LEARN
One of the things many motorists
have great difficulty in learning to
do properly is turning corners; not
. only with due regard for the safety
of himself and his passengers, but for
the safety of others as well.
It is difficult to 'coast around a cor
' ner at low speed, and if high speed
ii used the car goes too fast. The
novice driver should practice going
into second speed just before he
reaches the corner he is about to turn,
and then drive around at slow speed.
'Another detail every driver should
learn and practice is the "matter of
signaling. The law states that the
driver shall signal in some unmistak
able manner which way he is going to
turn. The lefthand drive makes this
easy. If the operator is going to the
left, he should hold his arm out in a
horizontal. This indicates to those
back of him they should not come up
behind him on that side. When mak
ing a right turn the car' should be
run close to the curb and the signal
given by waving the hand in a. small
circle with a forward swing, as if to
say: "Come on up on this side: I'm
going to turn the corner." The "come
on" motion is not prescribed by law,
but has become, a custom of the road.
If a sudden stop is necessary the
hand should be held upward. This
signal formerly was used by coachmen
on the box and is well known to all
users of the highway.
AUTO PRICES KEEP
PACE WITH THE H. C.
Automobile prices are keeping pace
' with' the general Jiigh cost of living.
Several auto factories have given no
tice in the last two weeks of advanced
prices on current models.
The Packard Motor Car Co. ad
vanced prices on all passenger cars
and trucks. Oh line 325, including the
'open touring and closed models, the
advances are from $300 to $400. On
the trucks the advances range from
$150 to $200.
The Peerless Motbr Car Co., of
Cleveland, advanced all models $140,
giving as a reason the ihcreasing cost
of labor and materials.
'' "The Cole Motor Car" Co. of Indian
apolis increased prices on its entire
' line $200.
The Haynes Automobile Co. has an
nounced an increase in price of $200
on 1920 models, to take effect at once.
The line will consist of a light six In
four body styles and four styles of
light twelves.
The 1920 program of the ,Buick
company calls for six models at prac
tically the present prices. The coupe
and sedan were increased in price a
" few weeks ago. . A

turers are reported to be considering
an "advance of prices on their product

PRACTICAL
The following composition on "The
Angelus" was written by a New York
schoolboy:
"This picture" was painted by a Ma
lay. It contains a man and a woman,
a pitchfork, wheelbarrow ad a church
steeple. The man and the woman are
very poor and they" have been digging
potatoes because they need them' to
live on. The potatoes look quite
small. Just at raaseti they hear a
bell -ring; it is the-Angelus; it means
they must pray. " So they bow their
heads' and pray ,f orbigger potatoes."
INSULATION HAS ONE
MAIN JOB, SEPARATION
"The purpose ' of insulation is just
the same everywhere," says J. G. Till
man, of Tillman Bros., owners of the
New White Garage. "Whether it is in
a power plant or in a storage battery,
its main job is to keep the positive
and negative sides of the circuit
apart
"But in a battery there are in all
three things that insulation has to do.
First, it must keep the positive and
negative plates apart; second, it must
allow free passage of the battery solu
tion, and third, it must resist the cor
rosive action .of this strong acid solu
tion. "Certain kinds of wood do all three
things and do them well, but the wood
must be selected with great- care, and
even then there is more "or less varia
tion, as with any natural product.
Wood- insulators are also difficult to
handle, as they 'must be chemically
treated, must be worked wet, and
must never be allowed to dry.
"Threaded rubber insulation, which
is now well known among car own
ers, has all the advantages of the
best grade of selected -wood, and in
addition it. gives the plates the advan
tage of the greater protective proper
ties of .rubber."
AND LITTLE MORE
"Scribson is dashing off another
novel."
"How long does it take him to write
a novel?" '
"About six weeks." 'k
"Good heavens 1 And what does he
putinto.it 7" . '".'',,
"About sixty thousand words."

MOTOR CAR (CONQUERS DESERT
Conquering the deserts of Mongolia
with American motor cars is one of
the .achievements of American engi
neers and pioneers, who have made
the wide waste (tracts resound to the
exhaust of the motor.
"The Chinese government now has
a motor line running across the wide
desertibetween Kalgan and Urga," R.
F. Thompson, the manager of a big
motor distributing agency in San
Francisco, said the other day.
"Porter Mickle, now a San Francis
co motor car salesman, made the
path-finding trip across the .desert at
the request of General Tinge of the
Chinese Republic," Mr. Thompson
continued.
"To cross the Gobi, between Kal
gan and Urga, before the motor line
was established was considered fool
hardy by the natives. The Gobi is
a stretch of sandy desert between the
two places, and it is iniesteu with
Mongol bandits, whose chief pleasure
in life seems to be to hold up cara
vans and take what they need and
ride away into the shifting sands.
"In the rainy season the skies liter
ally open their tanks and let fly. It
rains continuously -for days and weeks
and months, not gentle rains, but tor
rents that flood the entire country-asd
make the trails practically impass
able. "Through this mud Mickle fought
for days. At times, with coolies dig
ging the mud, the party made only a
half mile a day.
"Starting at Kalgan, which may be
reached by railroad from Pekin, the
party traversed a rough, rocky stretch
of country, through mountain passes.
Rapid travel is impossible; for, in ad
dition to the poor condition of the.
narrow trails, the road leading to the
Mongolian plains rises 11,000 feet in
less than thirty miles.
"After reaching the top of the big
plateau, about thirty miles from Kal
gan, the country develops into a vast
table land. These rolling plains give
way, near Tahil, to a chain of barren
hills, three or four hundred feet high,
and then cast stretches of rolling
plain, devoid of wells and without a
sign of life.
"Between Pong-Kiong and Udde, a
distance of. about 260 miles from
Kalgan, a descent is made into an im
mense basin of sand, which is the
desert of Gobi itself. Here travel is
ly difficult The sand causes
the wheels to chura and the tire wear
out quiCKiy.
"The desert is left behind at Tuerin,
a distance of 581 miles from Kalgan.'
From Tuerin to the end of the run the
roads are good,- and the 155 miles be
tween this point and Urga offer little
if any difficulty.
"The Chinese government now has
thirty-five cars' in this desert run and
has ordered sixty-five more, which
will be placed in service as soon as
they are received.'"
GOOD ROADS CUT
THE COST OF LIVING
"Out of war's transportation' chal
lenge has now come also a clear con
ception of .why we need and value
highways. Many have labored long
and faithfully to build roads, not traf
fic, and to complete the road, has been
to accomplish the goal. But today,
men labor for roads as one element
only as a means to an end, the new
desire being to secure economical
highways transport. The true test of
a road's value is in ita,power'to stim
ulate traffic over it, and having done
so, to permit its carriage at the low
est possible cost"
In these words Robert C. Hargraves
sums up' the new understanding of the
road situation In luV'chapter, "Motor
ized Highways," id the volume "Dem
ocracy, in Reconstruction,"' recently
published.

Its Tbrbensen drive gear transmits; 97 per cent of the
engine's power to the rear wheels. The average of other

The axle housings are forged steel, both stronger and

Its 35x5 pneumatic Cord tires the best made last
