AIR has taken the place of tho paddle
on most OF the roads. The hose which
contains the compressed air is run
into the car through window or door,

lie, leather strap, or beaten can get
1t the dust as compressed air does.
The Jet searches every crack and Granny
and drives the dust from the very
wood itself. Sometimes the women
turn the air upon the window casing
and in n iif,y it is clean of dust.
The man who makes air compressors
cited this novel use of compressed air
rs another point in favor of the claim
made by his craft that compressed air
was Just beginning to enter into the
common every-day work of the world.
tic added that few persons knew the
uses TO which compressed air was put
outside of stopping trains, drilling
roc6, and initiating bicycle tires.
Electricians think that this is the
electrical age" he said. "Well, per-
maps it is, so far as lighting, telephon-
inc, telegraphing, and welding goes,
but when it comes to the transmission
ri power they are talking too much.
They have worked and studied for
years to make an electric rock drill
which would take the place of the air
irill but they have not succeeded.
Hhey have tried to make an electric
rain brake which would bring n linn

hey will never catch up. 1t will not

hing with compressed air as the mo-
i've power, and they will be safer,
more easily controlled, will run as

pressor is n pump which is part of
stationary engine. The piston in the
tir chamber first sucks the air in, and
then forces 1T through pipe in the
reservoir. OF course the more air one
bumps into the reservoir the greater
pressure to the square inch one gets.
The compressed air works like steam,
except that it is cold and has not the
expansive qualities of steam. But
steam cannot be carried through pipes
out of doors to any great distance, for
1t would lose its heat, would condense,
and soon turn back to water

there is not belt, piece of shafting,
VI an electric wire, for all the ma
chiuery, from n little emery wheel to
twenty-ton crane, is operated by
compressed air. The shop is traversed
by large pipes from the air reservoir,
and from these main pipes smaller
pipes lead down to the machines.
Each machine, whether drill, planer,
shears, lathe, bending rolls, milling
machine, punch, drop hammer, press,
or cold saw, has its own motor or en-
CINE, and the mere turning of a valve
starts or stops the machine.
ga pneumatic.clock system has
lately been installed in the new Grim
inal Court building in Chicago. Pneu-
matte clocks are not new, for they
have been used ia Paris for twenty I'VE
years. Now over 10000 clocks are
operated and regulated from the cen
tral clock by compressed air.

there for all purposes, from running
clocks to operating dynamos for
electric lights. The central station
furnishes air mt pressure OF seventy
five pounds to the square inch. II is
sent around the city under the streets
in pipes, and is sold to customers by
meter, just rs gas is.
