m THE ELECTRICAL WORLD:

An advocate of electrical cooking
claims that of every 100 tons Of coal
used in q cooking stove 81 tons goes "a
waste.
An amateur electrician in Mon
treal named Eugene Baldwin, has
rugged up . wind wheel which, in con-
nection with . dynamo and storage
batteries. supplies all the lights he
needs in the house.
An Austrian has invented . flying
machine that moves through the air
after the manner of bees. At present
It il operated by q small steam engine.
but its inventor hopes to find some way
Of discarding steam and using elcctricir
ty in its place.
AT the close Of the year 1s9. there
were in Switzerland $50 electric lights
run by water power. IS plants for elec.
trical transmission of power, III accu.
mulator or storage batteries and l.05d
other dynamos and electro-motors.
The number of incandescent lamps run
by water power was lis, ea6 and of arc
lamps 9.7l6
The Syracuse, (N. W Storage Bat
terry Co has . street car propelled by
storage batteries running in Oneida.
The total run on one charge of the
batteries was 125 miles The car, it is
said. makes daily from 81 to 10 miles
without . break in the service. The
125-mile run was made on . seven-hour
charge There arc 81 cells used in the
car. The motor is 3O-horsc power,
and is wound for 100 volts. The car is
also lighted from storage cells
Trees are fclled by electricity in
the great forests of Galicia. For cut
ting comparatively soft woods. the tool
is in the form Of an auger. which is
mounted ON . carriage, and is moved
to and fro and revolvcd at the same
time by small electric motor. As the
cut deepens. wedges arc inserted to
prevent the rift from closing. and when
the tree is nearly cut through, an AK
or hand saw is used to complete the
work In this way trees are felled very
rapidly and with very little labor

"A Boston electrician has just com
pletcd n novel device for electrically
extracting from wood or rag pulp used
in the manufacture of paper, by series
of moving electric magnets. all trace.
of iron contained in the pulp by
means of = sprocket chain the magnets
are drawn through the pulp. then e!e.
vated to . higher level, where they de.
posit their picking of iron dust in a re-

when the magnets are in the proper
position. A jet of water also assists in
washing the magnets clean, ready 70
the next immersion in the pulp The
device is extremely ingenious and per-
fectly simply and practicable. and has
proved . wonderful success.
Two men were arraigned in New
York court recently for stealing elec.
trio power, the case being the first of its
kind in that city. Edward Gardner and
his brother-in-law have charge of the
exhibit Of the Roulette Cycle Co. of Gov.
entry, Eng. ut Madison Square Garden
Frank Martin. the electrician of the
garden, observed that the wheels Of y
bicycle hanging above Gardner's booth
were being turned ut . rapid rate by
some unseen power. On investigation
he found that the electric light wires
had been tapped, and were connected
with . small electric motor, which kept
the wheels in motion. 1t is said that
in = somewhat similar case the supreme
court in Buffalo sustained charge -
larceny about = year ago. 3.
The introduction of electric power
in the improvement of drilling and
quarrying machinery within the past
few years is evidently destined to work
. revolution in the accomplishment
Of tunnel engineering projects Exca-
vations that formerly occupied years
can now be made in few months. and
. striking reduction in the estimates Of
the time required for the carrying out
Of engineering plans is apparent It il
stated that the proposed Simplon tun-
mel is to be constructed At . cost and
rate which win place its predecessors
in tho shade. Motive power is now
easily obtained from water in the Swiss
mountainous districts, and the facility
with which electric power can be trans
mitted renders the site Of . generating
station a secondary consideration.
