IN THE ELECTRICAL WORLD.

IN The ELECTRICAL WORLD
Tho system of train lighting by dy.
namos and storage batteries Is finding
great favor in Great Britain.
"A man In Cincinnati claims to have
found process by which he II able to
electroplate iron, steel and copper with
aluminium The deposit is claimed to
be az hard as nickel, never tarnishes,
and does not fuse readily.
The vaults of the sub-treasury in
San Francisco are being fitted with
wires for protection from thieves. The
wires are to be between every two rows
of bricks, and any attempt to interfere
with tho cement or bricks will disturb
m electric current and sound . warn
ing.
"A new storage battery is being en-
ployed on the Chesapeake and Ohio
railroad, for use In connection with
electric lighting Of cars. Twenty-four
cells are placed under each car, and
they supply eight 16-candle power lamps
on the round trip from Cincinnati to
Washington
The Oldtown (Me.) Electric Rail-
road Co. and the Oldtown and Orono
Electric Railway Co. have consolidated.
1t is said to have been decided to build
the road from the terminus of the Ban
gor street railway on State street to
Oldtown. Freight and passengers will
both be carried on this line.
The necessary equipment for six
miles of electric tramway is now on its
way from this country to Siam. Six
generators, two complete steam plants,
twenty car equipments and extra parts
to last for six months make up the or
der. The road is to be installed in
Bangkok, and will be the first electric
tramway in Siam.
The Pennock primary battery To-
connective was tested on the Rock
Island steam road at Peoria, Ill, recent
ly, and seemed to work perfectly.
There was no slot between the tracks,
no steam power, no smoke, and no over
head wire. The locomotive is sixteen
feet long and seven feet wide. The
power is generated in primary bat
terry, the electrodes Of which are carbon
and zinc.
The longest span of telephone wire
In the world is said to be that across
the Ohio river. between Portsmouth,
O., and South Portsmouth, KY. The
wires at this point span the river from
pole on the Ohio side, measuring 1O2
feet above ground ITO the Kentucky
hills ON the opposite side, the distance
being SITS feet between the poles Tho
wire used Is made of steel, and its size
is No. 10 gauge.
Some interesting tests with alter
mating currents and . particular form
of magnet have been made in England.
Among the experiments shown was one
which illstrates . new method Of de-
tecting counterfeit coins. A genuine
coin, being . good conductor, was held
between the poles of the magnet, but .
lead coin. not possessing that necessary
qualification, immediately dropped
when placed in position.
1t is stated that the now hotel Wal
dorf in New York is to be fitted with
telephone communication between the
Office and every room in the house.
This is q system in use in the Adelphia
hotel Of Liverpool, England. and as q
feature of hotel service is an important
one. especially in the saving Of time.
Instead of pushing button and watt
ing for a hall boy to answer the ring,
guests can communicate their order to
the Office at once, and have it filed in
one-half the time. I
I'm lighting the Worlds fair. 92,622
incandescent lamps, of 1o-candle power
each will be used, according to present
estimates. The contract for furnishing
and maintaining these lights has just
been let to George Westinghouse, jr.,
for $3.50, 900. This Is more than 81, $780,
600 less than the Edison Thompson
Houston electrical ocombine, or trust,
first asked for the work. This immense
saving was effectet by rejecting the
bids and readvertising. Mr.. Wcsting.
house is required to file a bond for
81 ZOO, 900 by June 10, to guarantee the
execution of his contract. In
to the incandescent lamps,
about 5000 arc lights of 1000 candle
power each will be used The contract
for these was let some time at $50 per
lamp
