IN THE ELECTRICAL WORLD.

The electric light of 20, 900, 900 cans
dle-power in the lighthouse at Hanst-
holm, coast of Jutland, said to be the
most powerful light in the world, isnow
lighted for service
Electricity derives its name from
the Greek word for amber electron, be-
cause Thales, about 600 b. c., discovered
that amber, when rubbed, attracts
light and dry bodies, and in the twelfth
century the scientific priests of Etruria
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-being
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
traveller who has recently returned from
! Thorn, Prussia. The balloon was 13X15
metres, and required 1000 metres of gas
to fill it. The car 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.
I'm view of the fact that the statis-
tics on the use of the telegraph during
the year 1890 in the various European
countries will shortly be published, it
is interesting to note that the number
OF kilograms for every 100 inhabitants
during 1889 is as follows. Great Britain,
1853; France, 49, Germany, As; Italy, %;
Austria, 20; Hungary, 10; Russia, 0. For
1883 the figures are: Great Britain, 40;
France, so; Germany. ~; Italy, 80; Aus
tria, %; Hungary, 10; Russia, ..
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 fat
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 1876 cities have
2S7 electric lines. Boston has 313 cleo
trio motor cars; st. Louis POI; Roches-
ter, 200; Pittsburgh, 10; Cleveland, 1872;
Minneapolis, 40; st. Paul, IS; Cincin-
natl, n; Nashville, 81 Davenport, Ia,
60; Milwaukee, 50; Richmond, 49, Utica,
80; Scranton, Pa, 20; Albany, 10; 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 q Danvers road in this State,
and six in Dubuque, la.
Not many months ago Il new system
of sending pictures by telegraph was
described in the electric journals. The
principle of this process was the divis.
ion of the picture to bc 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 tx
the receiving station.
p An industry which promises to at
4 tain very considerable dimensions is the
q manufacture Of the electric blower
v which. started not many months ago
d is now rapidly growing. This appa
Il ratus was primarily designed for use il
dynamo and engine room of steamer:
e and other places where the space is lin
@ tied and where at the same time RAPID
and thorough ventilation is absolutely
S necessary. Owing to the extreme com
n pactness of the blower, it may b.
q placed in the smallcs. room, and proves
c a most powerful exhaust. 1t was speed
l. lily seen that such device was invalua
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,
