IN THE ELECTRICAL WOULD.

"A daily paper in Birmingham. Eng,
is printed and folded by electricity.
There are now current about four
hundred titles of electrical books A
few years ago an electrical library Of
ten volumes embraced all the available
literature on the subject-N. Y World
"A neat little improvement has re-
Gently been introduced into the domes-
tic electric annunciator. Each new call
is made to restore to its place the drop
which indicated the previous call, so
that it is no longer necessary to depend
upon a servant or attendant to do it
The Australian railway commits
sioners have recently entered into an
agreement with the Brush Electrical
Engineering Co to run for six months
on the South Australian railways a
train fitted with the electric light. The
inaugural trip of the train was made in
September
Joseph B. Strauss, of Cincinnati,
claims to have perfected an electrical
signaling device by which fireman at a
hose nozzle can communicate with the
man in charge of the fire engine. Tests
made by the Cincinnati fire department
seem to indicate that the device pos
sesses merit
-Riveting by electricity is now prac-
ticed in the following way: The bars
or pieces of metal are placed on the an
vii, the rivet dropped in place and held
firmly, when the face of the bar is COW
cred with insulating material, except
at central point. where it is left bare.
The current is then turned on, and the
rivet is riveted in jiffy.
The original plans for the electric
lighting at the Worlds fair called for
100, 600 incandescent lamps 1t has al
ready been found necessary twice to
increasd this allotment, and according
to latest advices the number required
will fall little, if any, short of 800, 900.
One-third of this number will probably
be required in the Electricity building.
"A new system of railway conduits
has been invented which is dependent
for its insulating qualities in wet wealth
er upon the principle of the diving-ben.
The wires are supported in the top Of
an inverted trough made n short Sec
tions with closed ends, but open at the
bottom. so that when water fills the
conduit the air contained in the in
verted trough will prevent the water
from rising to the height of the wires
Trouble from electrolytic action
has been experienced in Paris owing to
the poor insulation in many of the
underground systems used for lighting.
The gas and water piping of the city
has been pitted and perforated in
several places where the insulation of
the neighboring electric conductors has
broken down. Similar actions have
taken place in this country in one or
two localities due to the grounded
currents of trolley roads.
The post Office department, it is
said. has under consideration some
novel plans for the electric distribution
of mail matter at the Worlds fair. sub
mitted by the United States Rapid
Transit Co.. of Chicago. The plan pro-
poses cables high enough to clear all
buildings between the points named,
and on these cars would be sent by
electric power at high speeds, and so
arranged as to dump the mail bags at
given points, and return with other
matter sent up in an elevator.
Successful experiments have been
made in France relative to the intro
duction of telephones for use in war
fare. The telephopists are organized
in sets of two men each, each set being
provided with equipments for a mile
line. The very simple receiving and
transmitting apparatus remain attached
to the military cap. and the wire on
reels in a sort of breastplate, being so
light that a mans ordinary equipment
weighs less than six pounds. At dis
tance of fourteen miles an order for an
assault, setting in motion two army
corps, was received and put in exeeu-
