Solids vi: Pneumatics-which?
in. .' '
Note At tHe-,Trock and Tractor
meeting of the Society of Automotive
Engineers held in Chicago a paper en
titled "Relation of Solid and Pneuma
tic Tires to Motor Truck Efficiency"
was read by S. V. Norton, of the B.
P. Goodrich Rubber Co.
The following is the last install
ment of an abstract from his paper
whicH;haa been pronounced by ex
perts as the most authoritative treat
ment of the subject ever made. Mr.
Norton is widely known as a trans
portation engineer, a tire expert and
as the author of "Motor Trucks of
America 'and "The Motor Truck as
an Aid to Business Profits."
Having reviewed the engineering
features and the practical operating
features in preceding installments of
this series, let us now see what the
operator faces in so far as tire service
is concerned. As the nature and ex
tent of service of the maintenance and
renewal of solid tires are well known,
it seems unnecessary to comment on
them except to say that years of
study and competition have developed
this end df the business to a high de
cree of perfection, so that the oper
ator can depend upon many well
-equipped service stations for instant
attention, either in the day or night.
The maufacture of heavy duty
pneumatic tires of six inch section
and larger, is, however, a relatively
new development, less than a third of
the manufacturers of passenger car
tires have started actively to make
heavy duty pneumatic tires, for they
realize that the job of building a tire
which will stand up under the use and
abuse to which it is subjected nowa
days is no teasy. Moreover the task
is not finished when the tire come3
out of the heater. It must be sold to
thedealer, who, in turn, must not only
stand behind' the tire, but place him
self1 in position to give the truck op
erator service.' This means he must
install a high-pressure air-pump, re
pair materials and molds for vulcaniz
ing and in most cases a service car
for emergency calls as it must be re
membered the tire is apt to fall away
from its base and it cannot be driven
It may be said, without fear of con
tradiction, that the tire companies
themselves are not as yec prepared to
give really efficient service in all
parts of the country. In fact, even
in the principal cities this phase of
the business has not been fully devel
oped. In the smaller tqwns there are
almost no airtanks or pumps to keep
tires properly inflated. Tumps on
trucks themselves are reported as not
always dependable, sometimes requir
ing from 15 minutes to a half an hour
to secure the desired pressure in a
By far the most serious and diffi
cult phase of giving set vice with
heavy duty pneumatics, and that
which causes the most concern to
truck operators, is connected with the
repair. In fact, the chief complaint
in regard to pneumatic truck tires
aside from their high initial cost, is
that they are subject to injuries, cuts
and damage generally of such a na
ture that they cannot be repaired ex
cept at the factory where they; are
made, or in a few cities at a factory
branch ,and often they are damged be
yond all repair. This is not only ex
pensive, but frequently necessitates
the purchase of more than one set of
spares should the first set be injured
while the others are being repaired.
Oftentimes the principal cost of pun
ctures or blowouts is due to the nec
essity of laying up trucks awaiting
new tires, due to stock shortage, or
Bending the damaged tires to the
nearest factory branch for repair.
Moreover, repaired casings frequent
ly deliver but small mileage due to
the overcure of, the joined portions.
This danger is most difficult to over
come i nthe large sections due to the
longer cure required to vulcanize the
interior portions of the new part of
the casing. No doubt this feature
will ultimately be corrected.
The tread seems to give less trou
ble than the side walls which are more
susceptible to rut wear and overload

Who pays for the advertising?" is
still propounded by some occasional
mossrcovered or mildewed 'mind. All
The movement toward the use of
pneumatics should not be condemned
however, for undoubtedly it will be
the means of increasing the scope of
usefulness of motor transportation.
The question is too new to be de
cided theoretically or from such
meager records as are now available.
The field of each type of tire may
be separated into three classifications
within which the operator may reas
onably place his installation, and se
lect his equipment accordingly. Thees
may be called: (1) the imperative
field; (2) the economic field; and (3)
the optional field.
The factors that would bring a
truck within the "imperative" field
for solid tires are: reasonably hard
roads surface, dependability of deliv
ery, regularity of delivery ,and heavy
loads with frequent overloads.
If devilery must positively reach
its destination without fail at time
promised; if regular delivery is a
more imDOrtant factor than either
SDeed or cost of delivery, or if it car
ries over loads beyond the rated cap
acity of the tires, solid tires should
Similarly, the factors that would
bring a truck within the "imperative"
field for pneumatics are some combin
ation of the following: Traction on
any kind of road surface, or off the
road, with cost subordinated; speed
with cost subordinated or protection
of merchandise from road shocks.
The factors that would oring a
truck within the "economic" field for
solid tires are: Short hauls in cities
where speed is relatively unimpor
tant; heavy loads with tendency to
overloads; traffic congestion which
reduces average speed; load'ng and
unloading delays and need for low
Similarly those that would bring
the truck within the "economic" field
for pneumatic tires are: Road condi
tions which will not prematurely de
stroy the tires;, long hauls; high av
erage speed; relatively light loaftls
with no overloads; tire service condi
tions good and low cost subordinated
to quick service.
In analyzing the "economic" field
the operator must decide first wheth
er he can avail himself of the poten
tial speed pneumatic tires would give
him. This, of course, includes the
possible delays he may encounter due
to tire trouble as a result of bft road
conditions and those he will find pro-j
vided the tire service conditions in his
locality cannot be depended upon.
Next he must be sure that the featur
es of his service provided by pneuma
tics will justify their extra cost.
The distinction between "economic"
and "optional" fields is difficult to
make. In fact, the decision as to
which is the better equipment may be
purely a matter of personal opinion,
without strong factors on either side.
Hence, I shall not attempt to define
them. One of the most interesting
significant developments which I have
noticed in studying this subject, how
ever, is the growing tendency among
truck drivers to use pneumatic tires(
on front wheels where the need for
protection from vibration is the great
est ,and solids on the rear, to carry
the burden of the load. This practice
has much to commend it, and should
steadily grow in favor.
In concluding, I should like to urge
that designing engineers study to de
velop such cushioning effects as may
be possible through other means than
tires, such as, cushion wheels, im
proved springs, shock absorbers, etc.
L While I realize that no mechanical de
mise is so resuent as air, we nave a
long way to go before we overcome
the difficulties of making it serve as
acceptably in puncture-prool and fool
proof rubber tires, although the in
dustry is making notable progress in
A careful study of the points
brought out in the foregoing should
be of material value to the truck own
er in deciding which type of tire to
uce. If he closely considered all the
factors involved, as) mentioned here
in, he 'Will undoubtedly be able to
choose the tire best suited to his
sanitary, dust proof mentalities have
long since stopped bothering.
The .Editor, being an advertising
fan, prefers the answer of the enthus
iastic ad salesman: "Nobody pays
Nobody pays for the labor saving
machine that reduces factory over
head and increases production it
pays for itself.
Nobody'lpays for the motor truck
installation that decreases delivery

Board of Health. This is particularly
true of the incidence of smallpox.
Since the first of the year, the num

number of cases dropped to 15.
In Gila County there were 16 cases,

Although Arizona has no specific
law insisting that the eyes 'of babies
shall be protected against the possi

accorded in 2,843 births.- It was not

note that 371 births were attended by
More than 25 per cent of the babies,

Forming a Child's Ideas.
Priceless opportunities belong to a
mother to give to the baby, with his
whole life before him,! the true foun
dations of character and chances of
future happiness and greatness-. So
the first thing a wise woman does is
to reason the matter out, deciding on a
method of action which can be pursued
with as little deviation as possible.
Preparation Is needed, for just as love
does not bestow a mysterious Instinct
as to the proper physical treatment of
a baby, so affection alone will not
prove a sufficient guide or teacher In
the matter of character training. One
has to cultivate the power of restrain
ing Impulse, of infinite patience and
Infinite self-control and a nrm grasp or
those principles which underlie the for
mation of character. By possessing
these powers herself, the mother Is
able to direct a child's conduct and to
suggest motives to him at a time when
his impulses are natural and his Ideas
yet unformed, when he will learn lit
Early Irish History.
In the earliest time of which there
Is any record, Ireland was Inhabited
by tribes of the great Celtic family,
to which belonged the ancient Brit
ons of the larger Island, and the Gauls
of the country now known as France.
Bach tribe had Its chief, and after a
time a supreme monarch came to the
front. One of the most famous of
these was Brian, who overthrew the
Invading Danes In the battle of Clon
tarf, fought In the year 1014 near Dub
lin. He was slain In his tent at the
close of the fight. After his death
the supreme monarchy was often In
complete abeyance, misrule and an
archy widely prevailed and the ancient
form of society was largely broken up.
It Is1 said that Roderick O'Connor, son
of Turlough, was the last of the mon
archs of Celtic Ireland. From that

MAKES THE SAPPHIRE BLUSH
Radium Treatment Turns the Cheaper
Stones to Rubles Which Com
mand the Highest Prices.
Modern science has not brought us
very much nearer the magic stone of
the old philosophers, but It has enabled
later ocperts to play some surprising
tricks with the existing materials of
the jeweler and lapidary. The old
alchemists set out to discover the phi
losopher's stone, and achieved gunpow
der and other adjuncts to civilization
as the accidental by-product of their
original inquiry. Their less credulous
descendants reverse the process; the
Invention Is made first and Its applica
tion to magic Is discovered afterward
The existence of the electric furnace
makes 11 possible to create diamonds
that are the veritable stone, and to
fuse chipplngs and fragments of rub;
Into one complete jewel. Now arrives
a report that with the aid of radium
successful transformations have been
made in the appearance, If not in the
nature, of certain precious stones. A
sapphire, it is said, has been turned
into a glorious ruby by long exposure
to the effect of radium. Chemically
considered, this Is not very surprising,
for the two stones are both examples
of corundum, and the mysterious acci
dent of color is the principal difference
between them. If a sapphire can be
made to blush hard enough for Its
mistake In not being a ruby, pre
sumably It could blush Itself into a
most accomplished example of the
more valuable stone.
TAKE IT EASY IN .THEATER
Japanese Customs That Seem Odd to
Those Accustomed to the For
malities of the West
Japan must be a happy land for
theatergoers, because In that land
seats are not paid for In fact there
are no seats. The Japanese much pre
fers to squat, feeling, no doubt, much
more at 'home in this comfortable at
titude. Seats, however, are- usually
brought for the use of any foreigners
who may be present. There are no
hard and fast laws of convention. The
Japanese playgoer may do as he
pleases; he may eat, drink, smoke
and criticize to his heart's content.
Conversations are carried on, and, If
they mertt It the actors are met by a
storm of criticism and chaff. When a
man enters the auditorium he removes
his boots, and if the weather Is hot,
any clothing that appears to him to
be superfluous. The naive frankness
of the actors' prompter is rather de
lightful, for if an actor forgets his
lines the prompter comes on the stage
and, quite openly, points out to the
actor where he Is wrong. A boy Is
kept for the express purpose of walk
ing on the stage and wiping the per
spiration off the actors' faces; this
duty he carries out without disturbing
the even tenor of the play.
Ants are not the only insects that
practice the cultivation of mushrooms,
although for a long time It was thought
that they were the only creatures of
a lower order than man that possessed
the Intelligence to follow such an agri
cultural pursuit. Bouverle, the ento
mologist had found that a certain
wood-boring beetle, known as the bos
trychlde, Is as familiar with mushroom
cultivation as Is the species of ant of
which so much has been written. Pro
fessor Bouverle discovered that the
beetles In question bore holes In wood
and half fill them with a prepared
fungus which makes an Ideal mush
room bed. The garden Is carefully
spawned and In course of time the
mushrooms appear. In this way the
beetle provides itself with a food suf

How to utilize Wood Waste.
The utilization of wood waste Is one
way recommended to cut down the
high cost of living. Here are some ar
ticles made from sawdust and aningie
waste which the New York College of
Forestry Is exhibiting in its efforts to
show how the waste of the sawmill
can be utilized to cheapen the cost of
living: "Silk" socks, sausage casings,
phonograph records, paper milk bot
tles and tanbark shingles. The "silk"
looks like silk and feels like silk, but
Is much cheaper than silk. The sau
sage casings are made by treating the
wood with chemicals that turn It Into
viscose, and rolling' this Into thin aims.
