N I T A L I A N has invented an elec
tr ic a ll; operated machine for pro­
pelling distinctive odors by which
he purposes to produce in a M ilan the­
ater a “ Symphony o f Odors.” The in­
ventor insists that a degree o f harmony
may be sensed through the olfactory
nerve not unlike that sensation we term
music when sensed through the audi­
tory nerves. Instead o f a “ Polonaise
in E F la t,’ ’ he would give a “ Fantasie
in V iolets,’ ’ or a “ Nocturne in Apple
Blossoms.’ ’ B y combining a number of
these instruments, he declares he is able
to produce arpeggios o f perfume, har­
monics o f fragrance and haunting
nuances o f scent which w ill rival, i f not
surpass, the crashing chords and melodi­
ous phrases o f master musicians.

One More V ictory fo r Science.
Until the aid o f science was invoked
the work o f unloading cars loaded with
coal in winter in Philadelphia proved
to be a heavy task, fo r it often hap­
pened that whole trainloadB arrived
with the coal frozen into a solid mass.
Science built a concrete and nearly air­
tight house at Greenwich Point, into
which 21 loaded coal cars may be backed
at one time— like so many pies in an
oven. Here, in a temperature o f 150 or
more degrees, the solid contents o f a
car is thawed loose from the sides. In
40 minutes or so, the cooking process
being complete, the cars are taken from
the oven and hoisted over the ship,
when the coal runs out easily. That hot
air can do to 21 cars in 40 minutes what
it took 100 men a day to accomplish.

the bullet was passing through a space
o f 10 inches. This bullet was fired
through a thin piece o f wood, and the
film showed a curious situation. The
wood did not show any e ffe c t from the
impact o f the bullet until the bullet
had passed completely through it. Then
splinters began to form, the stick split,
and fin a lly fe ll to pieces. N o camera
shutters can be used with this appara­
tus. A series o f electric sparks are
flashed at the rate o f 100,000 a second
and a picture is made with each flash.
The film is carried on a wheel 3 feet
in diameter that makes 9,000 revolutions
a minute.

Shock Absorber fo r Wheelbarrow.
A gold medal was recently given in
France for a shock-absorbing attach­
ment fo r the common cr garden variety
o f wheelbarrow. The shock absorber
consists o f two uprights, one on each
side o f the wheel, at the bottom o f
which the axle is inserted so as to bear
against vertically supported springs.
The device is intended not only to save which is detachably whem connected
any fragile load carried on the wheel­ to the ladder. The hook engages the
barrow, should an obstruction be struck inside o f the window sill, and the cas­
ing lies along the sill. In this casing
is a compression spring, and fastened
to the string are jaws which engage
the top o f the ladder. I t takes only a
few seconds to whisk this device from
the top o f a closet or corner o f a room,
fasten it to the window sill and throw
it out. Then the clumsiest o f persons
can descend it, the spring support mak­
ing the descent much easier than it
would otherwise be. This form o f fire

Experiments extending over fiv e
years have demonstrated that hay cured
by steam heat is preferred by stock to
the sun-dried article, and chemical an­
alysis confirma this praetieal test by
showing that the percentage o f protein
is higher in artifica lly cured hay. The
method ealls for a complete steam plant,
where steam heat is secured from the
exhaust o f the engine. The freshly
mown hay is drawn under a shed and
pitched onto conveyor belts which earry
it to the top o f the building used in
steam drying. The hay is carried back
and forth over steam eoils nnderneath
the conveyors seven times. An even
heat o f 240 degrees F. is maintained,
and the hay remains on the conveyor
from 20 to 40 minutes. When it is dis­
charged it is well eured, o f better color,
and the leaves are preserved in better
shape than hay eured in the fields in
the ordinary way. The method lenda
itself to co-operative action among
farmers.

M PR O PE R conditions o f the nose
and throat are not only dangerous
to health, but stunt the physical
and mental development o f the child.
Colds in the head, catarrh, adenoids
and enlarged tonsils are the most fr e ­
quent o f these improper conditions
found in little children.
Adenoids are small masses o f soft
tissue normally found in every ch ild ’s
nasal passages between the back o f
the nose and the throat, which through
catarrh or other causes may become
enlarged and block up the air passages,
in terferin g with breathing through the
nose and forcing the child to breathe
through the mouth, preventing proper
inflation o f the lungs and stunting the
development o f the chest. They keep
up a constant catarrhal condition near
the ventilating tube leading from the
throat to the ear and in this way im­
pair the hearing o f the child.
Another common throat disease is
enlarged tonsils. The tonsils are small,
almond shaped bodies situated on each
side o f the throat. They have a cer­
tain purpose, and I do not believe in
the indiscriminate removal o f all en­
larged tonsils. In fact, I condemn what
I unhesitatingly call the “ massacre of
the tonsils’ ’ so often chosen as the
treatment o f enlarged tonsils.
The
cause is in many cases not in the ton­
sils, but in the general condition o f
the patient. Proper medicine and hy­
gienic treatment w ill cure many cases
without an operation. Only when the
tonsils are enlarged, hard and fibrous,
seriously interfering with speech and
swallowing, should they be removed.
Prevention is better than a cure. I f
a child catehes a cold, do not let the
cold ’ ‘ wear its e lf away. ’ ’ Treat it at
once or it may lay the foundation for
adenoids and enlarged tonsils.
