IN THE ELECTRICAL WORLD.

1T is reported that the cars ON the
electric railway between Leicester
and Worcester; Mass, will be operated
by storage batteries.
Gray and Weller, in 1929, first
transmitted electricity from one point
to another, and distinguished conduct
ing from non-conducting bodies.
so popular is the new electric rail-
way between Minneapolis and st. Paul,
Mimi, and so great is the traffic on it,
that the steam railway company has
taken off five short-line trains, it no
longer paying to run them.
The locomotives of the vestibu1ed
trains of the Chicago & Eastern Illinois
railroad are fitted with electric arc head
lights. A small dynamo and engine
placed just behind the large lantern
shell runs the light, which is much
more satisfactory than the oil lamps in
general use.
An electric line between East St.
Louis and Belleville is now an assured
fact. It will be single track, and,
with switches and sidings, will be about
IL miles in length Powerful motors of
the high speed type will be prominent
feature of this line. A local paper says
that SO miles an hour is to be guaran-
teed.
1t has been noticed that platinum,
when placed in an electrical current, is
heated to dull redness. This fact is
the basis of an invention of an cleo
trical saw, which will cut quickly and
neatly the hardest wood The device
is made up of steel wire, upon which
is deposited metallic platinum: By con-
Meeting this compound wire with the
terminals of four Bunsen batteries the
platinum is heated to dull redness,
and the saw is ready for business.
An inventor in Kansas City, Mo-, is
said to have invented type-writing
monograph. The Electric Review, in
commenting on the alleged fact, says:
eve believe phonetic writing from a
photographic record is entirely within
the range of possibility. Silent letters,
of course, can not count, but each letter
sounded--those which are recorded by
the phonograph-m be also printed
as letter. When such an instrument
is an actual reality, it will meet with a
warm commercial reception
The highest elevated railroad in the
world is about to be built in Naples,
Sicily. 1t is intended to connect the
central part of Naples. with the Corso
Vittorio Emanue1e. It is designed by
Civil Engineer Adolfo Aveno, and the
estimated expense will be about 81 ,OO0,-
000 The road will be suspended from
towers 100 meters high, in which will
be elevators to carry passengers to the
stations. The road will be operated by
electricity, generated by the force of
the waterfall Of the river Serene.
The advantages of the electric rail
way for mail and express service, says
the Electrical Review, are beginning to
force themselves upon the officials of
the express companies and the govern
ment. Already this service has been
esta blished in a western town, so far as
the express is concerned, and the peo-
pie of st. Louis want the electric roads
to get the mail service. A bill has been
passed by the Missouri state legisla-
tdre providing for an extension of the
powers of street railway companies so
that they may make contracts for car
rying mails.
The latest novelty in motors APP
pears to be Boston inventions null
tipolar machine-in which the arma-
ture is made to revolve around the field
magnets. This method of delivering
the energy to the motor from an out
side point or periphery, instead of APP
plying it to the center, as in the motors
in common use, would seem to have
some advantages The location Of the
field on the inside, while enabling COM
pactness in construction, greatly dimin-
