Recent visitors at vMcCook 'field, the
horn. of the enjlnperinr' division of the
air service at Dayjoii, Ohio." bay been
kstontshed at the gyrations of a brightly
painted three-wheeled vehicle which has
been dashine ' to and fro between the
ftuildlncs End among the airplanes on the
field under no visible means of control.
; It Is often seen to approach a group of
persons blowing Its horn wildly, and then
when apparently about to strike them, to
top short with screeching brakes, back
up with loudly clanging blow, make a
share turn to the right or left, and to
start off in the opposite direction.
LOOKS LIKE CIGAR
Great mystification has been shown as
to the method of operation of this car.
some visitors even wondering if perhaps
combination of the heat and newly
made home brew may not have had a
- deleterious effect upon their observation
powers. They are oft times considerably
relieved to learn that the car is actually
. performing as they have seen it, though
the mystery Is lessened but slightly when
they learn that the movements of the car
are controlled entirely by radio impulses,
'which are sent out from the radio sta
tion at the opposite end of the flying
field. The fact that there is no aerial
or antenna system visible merely adds
to the mystification.
The car Is of cigar-shaped construction
about I feet long, and runs on three
pneumatic tired wheels. It travels at
peed ranging from 4 miles per hour
to 10 miles per hour and the controls
are so finely adjusted that It may be
' easily steered along a narrow roadway.
" SOTS AND DASHES USED
An examination of the interior of the
ear shows an amastng and confusing
collection of batteries, switches, wires,
- vacuum tubes, potentiometers, relays,
magnetos, etc.. all of which are, of course,
necessary to the complete control of the
i , appartus.
- The most interesting part of the ap
paratus Is the "selector" which is in
reality the heart of the entire control
system. Various combinations of dots
and dashes are sent put by means of k
specially constructed' transmitter, each
' combination calling for the accomplish
ment of a certain operation of the con
trot apparatus. '
It la the function of this selector to
."decode" these various combinations of
dots and dashes which are sent out, and
to close the circuits to the desired con-
trola. Bo delicately is this selector con
structed, and so rapidly will It operate,
that it is possible to put into operation
any - one of 12 distinct controls in
, period of less than one second. -.',
W . . MMU MMMMMM MM M M. MMfAl MJ
t That , is to say, less than one second
lapses from the time any push button
, on the automatic transmitter at .the
' distant radio station is pressed until the
control on the car Is In operation. Such
speed of control has never before been
accomplished. This car has been con
; trolled equally well from an airplane and
trem a ground transmitting station.
- Thai, possibilities of radio control and
Its application to war time problems are
: almost without number. Radio control
can be applied to any mechanical ap
paratus that moves, whether it be in the
1 air. on the ground, on the surface of the
. water, or beneath the Water.
Huge land -tanks may be constructed
. and filled with 'T. N. T." and driven
- - to any deaired point along the enemy's
lines where the explosive can be fired
by means of radio, or it can" be applied
... In a similar manner to a boat, subma
rine, torpedo, or even an airplane and
' the explosive can be fired when and
where desired.
. - - There Is also an application in the
commercial field, particularly In plants
erbere long hauls between various parts

AUTO TRIP COVERS
TIRES ARE GETTING
BETTER TREATMENT
Motorists in general are each year
showing Jeclded improvement in their
treatment of tires, and are consequently
securing greater . benefit and ' longer
mileage from them. However, an appal
lng number of tires are still discarded
prematurely because they are victims of
negligence and abuse. -
According to the service department
of the Spreckels "Savage" Tire company,
one of the most prevalent tire mistreat
ments is bumping into curbs vand ob
structions, and passing over ruts or large
stones at high speeds The injury result
ing from such maltreatment is often
quite serious, since it frequently causes
breaks in the fabric foundation of the
ure wnicn wesjeen its integrity. The
tread after such, an injury may be in
perfect shape, but a few cords in, the
fabric may weaken from the blow and
gradually v work .through other plies of
fabric or cords and result in a blowout
An explanation of this condition is the
fact - that rubber is resilient ' and will
stretch, whereas the fabric is necessarily
not flexible enough to absorb the impact
of such a similar blow. ' , ,1
Thouh a tire may' seem on the-out
side to be' in perfect "condition,- a blow
out- may occur, sometimes days after
the tire Aas ;been - bruised, while ran
nmg along on a good road, or even when
standing idle, due to a bruise pinching
the Inner tube.
Bruises, of course, can not always be
entirely avoided, but careful -driving and
proper Inflation will prevent many in
juries of this kind.
"Any motorist who has ever tried to
shift his car into reverse while going
forward has either paid for a stripped
gear (if he was strong) or experienced
the feeling that the bottom of his car
was dropping out," says E. R. Harring
ton, local Maxwell-Chalmers branch
manager. "To try this without even
throwing out the clutch makes matters
Just that much worse.
"And yet, in San Francisco, Lou H.
Rose, Maxwell-Chalmers distributor in
that city, recently removed - the clutch
pedals from three Maxwells and then
spent an hour or so running about the
streets, shifting from one. speed to an
other; and Into reserve without the aid
of the clutch. The drivers would speed
up to about tO miles an hour or so and
then slam the gears Into reverse. The
cars would go ahead a few feet, then the
hind wheels would Jump a moment and
- the car would begin to move backward.
"Several hundred motor fans saw the
demonstration, which had been wen ad-
vertlsed beforehand, an?J when It was
over, followed the cars to the sales
rooms, where the covers were removed
, from the gear boxes and the gears
washed. They saw for themselves that
the gears were In perfect condition, with
out a tooth even chipped."
LENGTH OF. RIVER
For the first time In motor car hiatory
an automobile has successfully followed
the banks of the mighty Mississippi river
from its source to the Gulf of Mexico.
The unique trip -Just completed at Port
Arthur, Texas, has particular significance
for motorists who, appreciate continental
touring. It was made by "Truinaj Pear
son of Minneapolis, Minn., general man
ager and founder of the "Port Arthur to
Port Arthur . route" and .V Winnipeg to
Tampa line" of the Mississippi river
scenic highway system.
Pearson is the originator of the Mis
eissippl river scenic highway system and
other routes along the Mississippi anJ
dreams of a" great highway through the
rich Mississippi valley similar to the
Lincoln highway east and west.
The trip was begun In Winnipeg.
Snowstorms, blizzards, cyclones and hot
spells were encountered by the scout
car in the successful mission of blazing
what is called by some 300 cities and
towns it serves in 14 states and two:
Canadian provinces "America's greatest
north, and south automobile road."
Many predicted Obat, the proposed txip'
could not be consummated Ty an auto
mobile because there - war too many
gapstrurt -couldlAOt jtt :hrjdged, that
snowstorms' and mud an4" sparsely set
tied and wild sections with poor roads
would defeat the attempt. But Pearson
came through, a pioneer In a new and
successful venture.
The Virginia Islands have 250 automo
biles, or one to each 104 InKKbitants.
SOMEWHAT EXPE3TSITE
In Chicago the cost of hiring a taxi
cab is 20. cents for the first: rnjle and 10
cents for each succeeding quarter mile.

Eight Care of Spare"
Tubes Termed Need
. The man . who la accustomed to park
his shoes on the piano and to file his
. collars In the coal bin ought to throw
his spare tubes In the tool box. That
Is, he ought to If he wants to be con
sistent ; As a matter Of fact neither the
piano nor the collars would suffer as
much as the tube. In the opinion of local
Miller tire men. Inner tubes are usually
pacxea. in tne xactory in wax paper.
This paper win preserve the resiliency
and elasticity of the rubber, but It won't
protect It when thrown carelessly Into
the tool box of a car. The JolUng of the
car causes the tube to chafe against
the box and thrusts it against the sharp
edges or the tools. The tube that is al
ways ready for the roadside emergency
is the -one that Is wrapped In cloth or
paper, or better yet, encased In an in
expensive tube bag.)

The new Cadillac Type 61 carries with it, of
course, all of the positive assurance of sound,
enduring value which has always been associ
ated with the very name Cadillac
Needless iq .say, there is all of the old reliabill
zk ty,; resjbilbillty, and regularity of perform-ance-rmore
pronounced than ever because in
the Cadillac plant the passage of time is a
continuous process of improvement.
But in addition to these hidden 4 traits of
'character hich have made it the world's
standard of motoring efficiency theType 61
Eight Cylinder Cadillac brings you other posi
tive and quickly recognizable qualities which
immensely enhance ease and enjoyment.
Within a few.minutes from the time you hava
taken-the .wrHeel you will discern a more pro
nounced '' quality of resilient road ability than
the Cadillac has ever developed before.
In other words, it is our Judgment, that this
Type 61 accomplishes the greatest advance
yet recorded in overcoming -road discomfort
. and msuring riding ease. J .
Iiargely by way of simple but fundamentally
sound changes, such as lowering the center of
gravity without decreasing road clearance,
smoothness of travel has been surprisingly
improved.
Again, a recently adopted and equally simple
improvement in carburetor practice has
bettered Cadillac acceleration so that its pro
verbial, swift surge of power. is even more
immediately brought into action and mileage
per gallon of gasoline increased.
The new Cadillac gets away grandly, and
communicates both to the one at the wheel
and those in the tonneau, a sense of pent-up
reserve power that Is delightful.
The same simple changes that have given it '
a greater degree of road resilience have brought -with
them much greater beauty than before.
The Typel , is d delight to the eye not, ,
merely at the first admiring glance, but in
;i the wealth of attractive details which a closer ;
inspection reveals.
Experienced motorists will delight in the artis
tic and convenient arrangement of the Instru
ment board, the windshield and ventilator
improvements, the restful simplicity and
grace of the new steering wheel and controls,
the convenient inspection lamp, and other
refinements of a most pleasing character.
Incidentally, Cadillac coach work has im
proved upon'itself so that the new car comes
to you not only with greater charm of general
design but a far more Impressive and beau
tiful finish.
These latter are the lesser satisfactions the
real delight will come in the revelation of
greater riding ease and readability, and
swifter acceleration.
A delightful experience is in store for Cadillac
owners and non-owners alike. '
