IN THE ELECTRICAL WORLD.

The electric light of 2O,OJO,OOO can
dle-power in the lighthouse at Hanst-
holm. coast of Jutland, said to be the
most powerful light in the world, Is now
lighted for service.
Electricity derives its name from
the Greek word for amber, electron, De-
cause Thales, about 600 b. c.. discovered
that amber, when rubbed, attracts
light and dry bodies and in the tWel1th
century the scientific priests of Etrurla
drew lightning from the clouds with IRON
rods
The city of Appleton, Wis, is to be
lighted by electricity. In this there Is
nothing remarkable, but the reason
given for the resolution OF the city
council on the adoption OF the electric
light is an entirely novel one-bemg
that better light than gas is required
from the fact that at present so many
women are insulted nightly in the
streets.
An account of an interesting bal
loon ascension experiment is told by a
traveller who has recently returned from
Thorn. Prussia. The balloon was l3Xl5
metres. and required 1000 metres OF gas
to fill it. The ear was connected by
telephone with nearby fortress. The
apparatus worked splendidly both ways,
and the voice of the cOmmandant OF the
garrison could be distinctly heard at a
height of 600 metres,
In view of the fact that the statls-
ties on the use of the telegraph during
the year 1890 in the various European
countries will shortly be published, 1T
is interesting to note that the number
of kilograms for every 100 inhabitants
during 1889 is as follows: Great Britain,
163 France, IS; Germany, 45; Italy, 26;
Austria, 20; Hungary, 10; Russia, 9. For
1883 the figures are: Great Britain, l4O;
France, so; Germany. 40; Italy, 80; Aus
tria, %; Hungary, 10; Russia, 9.
The cutting of veneers is now done
by electricity. The veneering machine,
instead Of cutting or shaving around
the entire circumference of the log, as
usual, takes thin slice from the fiat
side of it. The logs are of any diameter
and are cut into lengths of ten feet.
The veneering cutting knife is fixed be-
tween two parallel shafts and the log
is carried up and down in front of it
with circular motion by revolving
cranks and is fed against the knife by
a rachel and pawl in the ordinary man
ner.
In the United States 1S5 cities have
2S7 electric lines Boston has 3l2 elec-
tric motor cars; st. Louis, 2O1; Roches-
ter 200; Pittsburgh, no; Cleveland 1872;
Minneapolis, 11O ST. Paul, IS; Cincin-
natl, r.; Nashville, 81; Davenport, Ia,
60; Milwaukee, 50; Richmond, 10; Utica,
80; Scranton, Pa, 20; Albany, lG; SYRIA
cuse, 10, etc. The systems represented
are all single trolley overhead. -Four
to ten storage battery cars are run on
the Fourth avenue line, New York.
Two storage battery cars are run on the
Beverly & Danvers road in this State,
and six in Dubuque, Ia
Not many months hgo new system
of sendihg pictures lPy telegr aph, fas
described in the electric journals, The
principle of this process was the divis'
ion of the picture to be sent into squares,
each square being numbered to CORE
spond with paper similarly prepared
and to be drawn upon according to the
direction sent from the transmitting
station by the number communicated
While applicable to pictures having only
straight lines, this process was not
found feasible for the transmission OF
portraits. For this purpose an improved
method has been suggested, by which
it is claimed that an exact reproduction
in chiaroscura Of the original photo
graph can be electrically transmitted tc
the receiving station.
An industry which promises to at
tain very considerable dimensions is the
manufacture Of the electric blower
which, started not many months ago
is now rapidly growing This appa
ratus was primarily designed for use in
dynamoand engine room of steamers
and other places where the space slim
tied and where at the same time rapit
and thorough ventilation is absolutely
necessary. Owing to the extreme com
pactness of the blower, it may be
placed in the smallest room, and proves
a most powerful exhaust 1t was speed
lily seen that such device was nvalua
Bile on warships, and its installation OF
the Baltimore was soon followed by it'
adoption on nearly all the modern war
ships Of the United States navy.
