TRENCHES
MUZZLE LOADING cannon, declared
obsolete a half century or more
ago by armament eperts. have re
turned in Europe, alone with the hand
grenade and armor, also believed of a past
age until the world war developed in all
It fury. French and Russian soldiers
are very frankly and openly wearing steel
helmets to ward off bullets and the hand
grenade has been one of the most ef
fective of trench weapons.
Now the British are equipping their
trenches in Flanders and France with
hundreds of muzzle-loading annon,
fnuiid to be the ideal weapon for trench
warfare But it is only in that the
weapon is loaded through the muzzle and
r"t through the breech, that the new
weapon resembles the ordnance of a cen
t ir ago. Otherwise, it is the most mod
f n of weapons invisible to the enemy,

!T will soon be possible for the tired business man to see a motion picture show
on his way home from work. The stenographer and the shop girl will be given
an opportunity to see Charley Chaplin's latest capers on their way down town in
the morning. A boon to suburbanites has been invented which threatens to reduce
considerably the popularity of the daily paper and the Six Best Sellers as "time
killers" to and from work
The invention is a motion ricture car. in which films may be shown to an
audience comfortably seated in an Inclined auditorium. The cars should prove ex-oeed-ngly
attractive to commuters They can be hooked up with either steam or
electrical cars, as the platforms are of standard sire, permitting standard coupling
devices.
The motion picture car is the invention of Antonl Truchan, of Flint, Mich. Mr.
Truchan has applied for and received a patent on his Idea. The cars can be made
to seat from 75 to 100 persons comfortably
The film reel operator is stationed in the rear of the car just above the last tier
of seats. The screen, of course, is thrown across the space where the front door
ordinarily would be. In between are the seats, the floor sloping gently downward
to enable everyone to see the pictures plainly. A peculiar arrangement of Mr.
Truchan's car is that the windows, too. are on a sloping line; so that between pictures
the spectators may look out without Inconvenience and a perfect circulation of fresh
air is assured.

Boats Stronger
Than the Crews
T
HE cruising radius of the latest
German submarine cruisers is said
to be limited only by the endurance
of the crew. Fitted with Diesel engines,
burning about ten tons of oil for everv
thousand miles, the SOO-ton submersi
bles have an oil storage capacity of fifty
tons, which would carry the craft S,00u
miles, the distance probably covered by
the submarines that made the journey
from Germanv around the north of
Scotland and through the Mediterra
nean to the Dardanelles
The oil capacity of the submersible
can be greatly increased, however, by
carrying many tons of oil in tho water
ballast tanks
Human endurance, however, will not
stand an indefinite stay on a submarine,
especially when quarters are more than
ordinarilv cramped by the carrying of
extra stores There is, too, a continuous
oozing of oil from the bulkheads and
doors throughout the ship, and this, cou
pled with the incessant pounding of the
engines at close quarters, taxes the en
durance of the most hardened navigator
of the undersea waters
Why H.-P.ls Used
to Figure Power
WHEN Bolton and Watt first placed
their steam engine on the world's
market, they arbitrarily declared
the drawing power of p horse to he
33.000 foot-pounds, or the ability to lift
33,000 pounds a ml-iUte. Power was
represented in termB of horse-power be
cause the steam engine was designed to
take the place of horses. The unit has
been used every since and probably will
endure long after horses have disap
peared from the face of the globe.
The following are the various values of
horse-power: 33,000 foot-pounds per
minute, 550 foot-pounds per second,
2,565 thermal units per hour, 42.75 ther
mal units per minute. The horse-power
of a boiler depends on its capacity for
evaporation. The evaporation of 30
pounds of water from 100 degrees
Fahrenheit into steam at 70 pounds
gauge pressure equals 34 1-2 pounds and
at 212 degrees Fahrenheit is equivalent
to a horse-power.
Tune-Deafness DE;FECT of the GREAT
T HE defect In many persons known
I as "tune-aeainess, or tne inabil
ity to carry or distinguish a tune, is
not an indication of lack of artistic or
poetic character. The fault Is with the
nerves. Musical appreciation extends to
a great extent on the exercise of mental
and physical faculties, and the delight in
music calls.for an alert sympathy between
the nerves and the cerebral faculties,
without which connection there is defi
nite musical lack, although the nerves
perform their ordinary function of com
municating sound to the mind.

deafness" among the great were Presi

RADIUM Cures
X-Rav DISEASE
X-Ray DISEASE
In EARLY Stage
EPITHELIOMA, the dread and curse of
the Roentgenologist, has been found,
in its early stages, amenable to
radium cure, so that a distinct step in the
advancement of Roentgen-ray science has
been achieved. Epithelioma is skin can
cer caused by the X-ray and has been the
cause of the loss of fingers, hands and
even the lives of Roentgen-ray experts.
At a recent meeting of the British Med
ical Association, the Roentgenologist sec
tion was notable for the large number of
disfigured hands, arms and faces. In some
cases epithelioma has spread to the chin
and chest. Skin grafting, freezing and
other desperate measures have been used
in vain to arrest the course of the dread
disease.
It Is now firmly established, however,
that radium rays will cure the malady in
Its early stages and relief has been ob
tained, even when the disease had ran a
couple of years Tho effect of radium on
long standing cancers, however, is nil.
It seems almost a paradox of radiology
that the accepted use of a heavy gamma
radiation from a Roentgen tube will cause
a diseased condition of the skin, wbicn a
similar radiation from a tube of radium
will cure The output of the Roentgen-ray
tube is almost wholly composed of hard,
penetrating, irritating gamma rays. The
radium discharges the beta ray in great
quantity, as well as the gamma ray. It is
the beta ray that has been proved beyond
question to be the efficient curatie power,
and it is only the secondary betas gen
erated by the gamma when striking any
resisting substances, that gives it its value
in the Roentgen-ray tube work. Hence, a
surface lesion of morbid cell growth, be
It hyperkeratosis or basal cell, is cured by
tho large output of soft beta radiation of
radium.
It is not possible that. If it were pos
sible to gauge the output of the Roentgen
rav tube in power enough to generate the
curative beta rays by impact on the su
perficial disease, it could be cured, as
well as by radium, but in so doing it
would be necessarv to discharge energy
enough of the hard gamma variety to be
highly injurious to the deeper tissue of
the vessels, muscle and skeleton.

and speed indicator for automobiles
has been patented by a trio of
Easton. Pa. inventors The deice is in
the form of a square board, to the top of
which tho license tag is attached. At
fhe bottom of the board is a speed indi
cator and pointer, the different speeds
being indicated by different zones in or

he was the first person to introduce
Bach's passionate music Into the re

tay she would give tho world to be able

that for her "music was noiss and noth

Highly Charged
Drinks Declared
to Be Dangerous
EFFERVESCENT drinks are becoming
more and more popular, but no-
comes a part of the medical profes
sion to tell us they are more unhealthful
than light wines and beers. Cider and un
fermented juices of fruits are declared far
superior to both, when physiological cor
rectness is considered.
The chief fault with the effervescent
drink seems to be that one calls for an
other, in ever pyramiding stle The
scientific explanation of this Is that tje
slight stinging or pricking ot tho palate
caused by the highly charged drink pro
duces immediately an increased flow of
saliva. The salivary glands are no more
susceptible to perpetual stimulation than
any other, and after each period of ex
citement one of depression follows. Thus,
while tho effervescent quaff may for tho
moment effectually quench the thirst, it
Is not long before tne thirst is back,
stronger than ever.
Another fault laid at the doors of tha
effervescent drink is that it is generally
charged with carbonic acid. Now the
stomach, especially when it is empty, al
ways contains a quantity of carbonic
acid for purposes nature knows best. When
to this natural supply is added the amount
in the effervescent drinks, nature is over
supplied and the general system suffers.
Certain physicians, in deploring tha
vogue of the effervescent drinking liquid,
hopefully assert that it is merely a fad
and that soon we will return to the mora
wholesome natural drinks of our fore
fathers. MUSIC Softens

VOLCANOES
Now Harnessed
VOLCANOES are being harnessed in
Italy Steam Is generated and from
the steam electricitv And the novel
part of the affair is that the power issues
from the volcano in the shape of steam,
but it is too full of impurities to be very
eftective in its original form So fresh
water steam is generated by means of tho
escaping steam
Borings of thirty or forty feet yield an
unfailing supply of steam at pressures up
-o more than three atmospheres, and of
temperatures up to more than 700 Fahren
heit The steam is found in Tuscany, near
the village of Volterra. in a volcanic he:
springs region.
The steam has been wasteful!? used In
small engines of an old. noncondensing
type, but in recent experiments the heat
of the springs on account of tho impuri
ties contained Is made to generate steam
from fresh water, and this is employed in
low-pressure turbines for driving electrio
generators The large area to be served
with electric energy from the earth's owr
heat, if present expectations are realized,
will include the neighboring cities of Vol
