N THE ELECTRICAL WORLD.


An advocate of electrical cooking
claims that of every 100 tons of coal
used in a cooking stove 90 tons goes to
waste.
An amateur electrician in Mon
treal, named Eugene Baldwin, has
rugged up wind wheel which, in con-
nection with a dynamo and storage
batteries, supplies all the lights he
needs in the house
An Austrian has invented a flying
machine that moves through the air
after the manner OF bees At present
it is operated by small steam engine,
but it's inventor hopes to find some way
of discarding steam md using electrici-
ty in its place.
AT the close of the year 1892 there
were in Switzerla nd 800 electric lights
run by water power, d; plant for cleo
trical transmission OF power, 12l accu-
mula tor storage batteries and I .G16
other dynamos and clectrO-lnOtor:
The mum Der OF inca ndescent lamps run
by water power was lis, ?:6 and OF arc
lamps 9,sl6.
The SYRACUSE On. 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 l25 miles. The car it is
said, makes daily from Ga to 40 miles
without a break in the service. The
125-mle run was made on a scven-hour
charge. There arc &c cells used in the
car The motor is a 3n-horsc power,
and is wound for 1870 volts. Tho car is
also lighted from storage cells.
Trees are felled by electricity in
the great forests of Gal;cia. For cut.
ting compa rativcly soft woods, the tool
is in the form of augcr. which is
mounted on carriage. and is moved
to and iro 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
hand saw is used to complete the
work. In this way trees are fellcd very
rapidly and with very little labor
Electrical Review.
"A Boston electrician has just com
plctcd novel device for electrically
extracting from wood or rag pulp. used
in the manuf cture OF PAPER, by series
OF moving electric magnets, all traces
OF iron contained in tho rnip Ey
means of sProckct chain the ma nets
are drawn through the pulp, then cic-
waited to a higher level, where they de-
post their picking OF iron dust in 4 re-
ceiving tray, the circuit being bcOllcn
when the magnets are in the proper
position. a jet of w-atcr aiso assists, in
washing the magnets clean, ready 10
the next immersion in the pulp The
device is extremely inge NOUS and per-
fectly simply and practica ole, and has
proved 4 wonderful success.
Two men were arraigncd in New
York court recently for stealing cleo
trio power, the case being the first of its
kind in that city. Edward Gardner and
his brother-in-law have charge of tie
exhibit of the Roulette Cycle Co. of Cow
entry, Eng, at Madison Square Garden.
Frank Martin. the electrician of the
garden, observed that the wheels Of II
bicycle hanging bovc Gardncr's booth
were being turned at rapid rate by
some unseen power. On invcstiCat ion
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 a somewhat similar case the supreme
court in Buffalo sustained charge OF
larceny Il bout Il year ago.
The introduction Of electric power
in the Improvement of drilling and
uuarrying ma chincry within the past
few years is evidently destined to work
a revolution in the accomplish mcnt
of tunnel engineering projects. ESca-
vations that formerly occupied years
can now bc made in IL few months, and
a striking reduction in the estilna teS OF
the time required for the carrying, out
of engineering plans is apparent. 1t is
stated that the proposed Sirnplon tuu-
mel is to be constructed at cost aud
rate which will place its prcdcccss ors
in the shade. Motive power is now
easily obtained from water in tho Swiss
mountainous districts, and the fin cility
with which electric power can be ira Us
mitted renders the site of generating
station a secondary considcrati ton.
This new tunnel through the heart
of the Alps is to be completed in 81
