IN The ELECTRICAL WORLD.
"A telephone line about five miles
long has been established in Iceland
and is regarded as great curiosity, be-
Ing the first ever established on tho
Island.
"A constable in Western CITY re-
Gently chained the armature of n dyna-
mo so that it could not be operated be-
cause the company had not paid up all
Its taxes to the city.
Much as has been accomplished in
the way of electrical inventions. the
chances are that only the outer edge of
the measureless field has as yet been
touched.-Inventive Age.
Italy is experimenting with pens
electrically controlled for the determin-
alton OF the speed attained by a vessel
between floating objects thrown from
the deck Of vessel herself.
"A third line OF telegraph between
Berlin and Rome, 1910 miles long, is to
be constructed through Bavaria and the
Tyrol, instead Of Switzerland, like tho
present lines The wire will be of
bronze, and three millimetres in diane
ter.
Port Arthur proposes to raise S75,-
600 to build and operate an electric
street railway to Fort William. The
assessed value of Port Arthur is s1,745,-
1888, and the present debenturo debt
is S15s, S55.-The Commercial, Winni-
peg.
From experiments made in Rich
mond, w., with electric heaters, it
seems probable that passenger coach
can be kept warm at an expense of two
cents IN hour, the current being sup
Piled by dynamo on the locomotive or
tender.
New York City has 1887 electric
lights at an annual cost of 500 each;
New Orleans has 1,O1O, at $3.50 each;
Philadelphia has 500, at S177 each; To-
ledo, O., has 400, at 800 each; Scranton.
Pa, has 1872, at 500 each, and SPRING
field, Mass., has 500, at $50. so ench.
domestic electric lighting is being
extensively introduced in Philadelphia.

street car builder in the United States.

build electric cars largo, and put them
on SIX or eight-wheol trucks. As long
ago as 1886 it was proved by me, here
in New York, that the eight-wheel car
was unsatisfactory. Running electric
cars in trains is also n mistake. to nv
mind, for the reason first mentioned. :"
1t has recently been noticed that
large number of light gold coins arc
in circulation, and the discovery has
been made that the sweating is ac-
complishcd by electrolysis. The scien-
title swindlor constructs an electro
deposition plant, using ten-dollar gold
piece as an nnodc and small metal
plato as cathode. The battery Is "set
In motion" and, presto in few min
utes fifty cents worth of gold is depos-
tied on the metal plate, and the gold
coin is worth so much less than before.
AS the gold is removed equally from
all parts of the surface of the coin, it's
appearance Is scarcely altered by the
process. only an expert being able to
detect the slight blurring of the design
and lettering.-Electrical Review
