"Kconomtcal operation with a slx-cylln-dcr
car, or In fact any car, may be said
to be attained when about fourteen miles
on one gallon of gasoline Is the average
over a fairly long period in the ubo of
that car," aaya Arthur Holmes, chief
tnglneer of the H. H Franklin Manu
facturing company. '
"Gasoline economy Is but ono of tho
many economies that can nnft should be
worked for on a car. It Is possible but
very seldom obtained by tho average
1 man, no matter what ar ho owns. This
merely Indicates that he has not the
knowledge of the different things that go
to mako up economical use of gasoline.
"In general. If one understood the com
bustion of fuel In the cylinder, ho would
havo ull that Is necessary to understand
economical operation. He should know
inai a certain amount of fuel, and this
mil prncucaiiy in every case bo gasoline.
'unra nir mixca wun it in order to
have It burn and thus produce power.
3t Is necessary that it should have tho
correct amount of air, although a llttlo
excess of air does very little harm. It
Is necessary In order to have economical
operation that each cylinder have a riir
reot mixture, and this problem is one
of distribution. If a perfect mixture
were made In the carburetor, distribu
tion would be easy, but In general today
11 Is a mechanical mlxtlirn of crnimllnn
and air, and tho correct distribution of
this Is not easy.
, "Ignition Is another feature of gasoline
economy, and Ignition should always be
at a point that would give maximum
rower.
DrlTlnsr Important.
"How a man should drive Is Important.
I If the operator holds out his clutch when
Eolng down a hill, and allows the engine
to run under Its own power, ho Is need
lessly using gasoline. If he holds out the
clutch when ho Is slowing up the car. In
stead of closing the throttle, he Is need
lossly using gasoline. In fact -every time
that tho brakes are used on the car and
the throttle not closed, and this can hap
pen by holding out the clutch and leaving
the throttle open, ho Is wasting gasoline.
teases, this valve should be adjusted to
the minimum possible and still have
Kood operation., Adjusting this needle
valve to the minimum really means get
ting tho right proportion of gasoline and
tilr, and today even In warm weather, the
gasoline Is so hard to vaporize that It
Is absolutely necessary to use the needla
valvo under soveral different adjust
ments when " starting up, and until tho
engine Is well warmed up. In tho win
ter tlmo the valve may be opened up
to twice Its regular opening In order
to get good operation when everything
lis cold. It Is very likely that If the
necdlo valve Is not closed down and the
motor warms up, from two to three
itlmcs as much g'asollno Is used as is
lseccssary. ,
"Another big source of gasoline lost
Is In small leaks. Very frequently tho
gasoline valve or some of tho unions
leak just a drop now and then, but
Inasmuch as this drop Is going on for
54 hours a day, It amounts to a great
deal. For this reason all such places
should be examined at regular Intervals
to liote their condition.
"Naturally tho carbuetor has a good
deal to do with the Bnsollne-conaumptlon,
but with a standard carburetor there
Is not a great deal of difference In Its
use of gasoline. But there are quite a few
things about a carburetor that can pro
duce economical operation, such as leaks
In tho float or air leaks around the car
buretor, and for that reason It Is very
desirable to give this part enough at
tention to know that It Is clean ana
in good operating condition.
" Touring in the country gives the best
possible chance for economical opera
tion, as It allows the motor to hn u?d
at a more economical point In Its power.
At the same time, driving at high speed
In the country does not give ecenomlca
operation as far as gasoline Is concerned,
because the wind resistance increases
so fast that tho amount of gasoline
used In covering any particular mileage
Is very much greater than If that same
mileage was covered at a slower speed.
Probably 20 miles per hour represents
the best speed for economical operation."
Eight Automobiles
For the Montreal
Fire Department
Montreal, Canada, has appropriated
funds and awarded a contract for the pur
elms of eight htgh-powered automobiles
for the use of the deputy fire chiefs of the
city. The Cadillac Motor Car company
was awarded tho contract for four of tho
machines and tho Abbott Motor company
the contract for tho others.
Tho eight cars for Montreol are to bo
of tho fifty-horsepower artillery roadster
typo and are to bo painted fire red,
trimmed In gold, and nre to meet a test
requirement providing for a speed of
forty-eight miles per hour, when fully
equipped for duty, and are required to
climb tho hill through the main thorough
fare of tho McGIll university of Montreal,
which Is considered a very sovorc test
for an automobile, on high gear. Hoth
companies have cars already In official
service In Montreal and have mado pre
liminary tests to tho satisfaction of the
city officials.

TROUBLE AUTO TRUCK
HURRIES TO THE RESCUE
Detroit pedestrians who have Inad
vertently wandered along the populat
ed streets instead of keeping to the
safer suburban districts, have recently
discovered that tho art of tree climb
ing Is handy thing to have "around
tho house. For ever and again they
have been startled out of their phll'-
sophical reveries by a sudden and
noisy apparition that has approached
with the speed, apparently, of the
Twentieth Century IJmlted and all the
Indifference of an Intoxicated Individ
ual who cares not whether he takes
the sidewalk or the street.
Tho apparition In question Is noth
ing more than the latest development
In "trouble wagons" as applied to the
equipment of a street railway company
and When 'It rushes by nonchalantly
hurdling a curb to take a more easy
riding sidewalk for a block or two, the;
pedestrian from his safe perch on tho
lower limb of a handy tree now real
izes there Is something doing down the
line in the way of a fire, a derailed
street car, or, mayhap, a serious- acci
dent to somo unfortunate who has fal
len beneath the wheel of a heavy car.
AN INTERESTING MOTOR
EXPERIMENT IN OMAHA
As an Instance of the precision with
which motor car makers are construct
ing their engines these days, so that
they run with the minimum of vibration,
an Interesting little fact, was brought to
light In the garage of he local Midland
Motor company's representative yester
day. An ordinary pencil was 'stood on enl
on top of the engine of a six-cylinder
Midland car and the speed of the motor
Increased from 175 revolutions er mlnuta
to over 2.C00 revolutions per minute with
out causing sufficient vibration to jar
or shako the pencil from Its upright position.
Tho runic! development of the motor
car In tho last few years has brought
about a surprising number of Improve
ments and refinements that have great
ly InM-onaed the reliability, tho sim
plicity of operation. But ono of tho
most Important results attained in tnis
steady march to perfection Is reduction
in nnt- of maintenance. In the early
days of tho Industry there was an Irnjires-

cause, for one reason, an automobile
consumed an unconscionable qunnltlly
of gasoline nnd oil. Tho situation
whether based on fact or not, suggested
the king with thho clepnant on nui
hands, tho beast eating him out of house
and home.
There can be no mlsapprchenson on
this point today because tho well made
cur Is. not a havenous consumer of fuei.
Its appetite has steadily decreased un
til it Is now reasonably proportionate
to tho amount of power demanded.
WATER KEPT AWAY WHEN
TIRES ARE BEING MADE
When water works Its way beneath tho
tread and breaker strip and Into the car
cass of a tire premature deterioration Is
certain to follow.
"In building up the carcass of a tire
out of frlctloned fabric, which means
heavy cotton cloth Impregnated with
rubber, we are extremely careful to use
only thoroughly dry material," says C.
B. Whlttelsey, superintendent of the
United States Tiro company's Hartford
factory.

In a veteran Studebaker car that had
been driven more than 60.000 miles, E. D.
Hopper made a privately conducted re
liability run from his homo In Joplln,
Mo to Detroit and Is now on his way
back. The trip won a big wager for Mr.
Hopper, as tho car required neither re
pairs nor adjustments between Joplln and
Detroit. Threo observers were carried,
one of whom was the stakeholder.
UNDERSLAJrVG
The Safest Car on Earth
"Every day you rend of cars turning turtle and people getting killed or seriously
injured. Until the Regal appeared in the field all undeslung cars were high priced
cars." People couldn't afford to uso them, so they had to take their chances in getting
spilled.
T IS DIFFERENT !
The Regal in undorslung construction is sold at a price within tho reach of all. No
one can nfford to take chances riding in any other style of car.
Underslung construction gives riding qualities not possible in overslung cars.
Underfilling construction means straight line drivo, and consequent big saving of
power.
Underslung construction means low center of gravity freedom from skidding and
a consequent big saving in tire wear. t
Underslung construction means elimination of side sway of body, and consequent
comfort to occupants and 25 per cent longer liie to tho car.
