IN THE ELECTRICAL WORLD.

"A scheme is ON foot to utilize the
sprrent Of the Bosporus to illuminate
constantinople.
by the Nissl system Of telephony,
which is = German invention, it is said
that any subscriber can connect him
self with the station independently of
the others.
From many quarters at the west
comes news that new telephone com-
panies are about to compete for busi-
ness with the Bell telephone sub-com.
panies The fight will be. no doubt,
another illustration of the survival of
the fittest."
Manager Griffiths, Of the Hamilton
Ont) Street Railway Co., is testing
plan to prevent electrolysis of water
pipes. An extra wire has been placed
IN the wires on 0uise street. Mr..
3riffiths thinks he will make a quick
return current and overcome the difii.
Guilty.
According to the London Electrical
Engineer, Mr.. Moissan has succeeded
for the first time in obtaining chro-
MUM in pure state in his electrical
furnace. A sample of forty pounds of
this rare metal was exhibited at re-
sent meeting of the French Academy
Of Science. He purifiesit in the pres
ence of q double oxide of calcium and
chromium.
One of the signs Of the times is tho
proposition of the superintendent of
the Hartford (Ct.) street railway to put
telephones in the street cars. operated
on the trolley circuits, but independ-
emily of the telephone exchange. Tho
message would be sent into car head
quarters and there transferred to the
exchange service. The man who for
gets to tell his wife what he wants for
dinner can in this way instruct her,
and other thing ad infinitum.
I'm an interview, recently published
In the Herald of Rochester, n. v. T.W,
Hawley states that the subject Of cleo
trical transportation on the Erie canal
is still under consideration, and that q
canal boat is now being equipped with
storage batteries for an experimental
trip. This boat will be operated, it is
said, between Albany and Troy. Mr..
Hawley expresses confidence in the
consummation of the project to trans
nit by electricity q portion of the power
Of Niagara falls across the state of New
York, and says that the work of laying
the cables east of Buffalo will com.

One of the great dangers of our
electric car system on our streets is, in
some cases, failure of ordinary brakes
to respond to the impulse Of the motor.
man. All troubles OF running over
come from an emergency in which the
motorman has but q short time to act,
and if his mechanism is not quickly re.
sponsiye, he fails to save the life or
limb he would like to save. In this con-
nection it may be said that = simple
device Of controlling the brakes and
current on trolley cars has been invent
ed by Boston man. As now in opera
ton, the mechanism of devices having
this object in view is more or less COM
plicated. There are too many motions
to be made by the man in charge of
car. and it Is only by the quickest and
most prompt movements that the mo-
tormen are able to control their cars in
. reasonably short time. In the inven.
ton in question all this has been over
come, with the additional advantage of
a great saving of power. A simple
brake rod, located in the center of the
platform near the dasher. surmounted
by . wheel seventeen inches in diam
eter, does all the work. The mechan-
ism for operating the power connected
with the brake is located under the |
platform of the car, and consists of two
gear wheels, . sliding rack bar. lug
and powl to throw the mechanism in
and out of gear, and an ingenious de-
vice TO let the power on before the
brake is released, which is, of course,
when the car is started ON an |
