The long-distance telephone has
been put in operation between Norway
and Sweden, and his majesty at Christ
lana can communicate directly by word
of mouth with his ministers at Stock
holm.
"A few years ago it was possible to
send but two Geographic messages in
opposite directions simultaneously.
Now seventy-two messages can be sent,
thirty-six in each direction, on one
wire without interference. Then, the
telephone was first exhibited on a line
the length of a building Now one can
talk with another 1000 miles away.
I'm an article on the present status
of electricity Arthur V. Abbott esti-
mates that the $50 electric roads in the
country now use $500 miles of track.
with 1900 cars, requiring engines of
100, 900 horse power, The companies
are capitalized for $195,00O, 900. In adj
dition to this, Mr.. Abbott figures that
we have over 400, 600 miles of telephone
lines in service, with 100,0 900 miles of
underground cable.
1t is believed that lightning is Wis
ible at distance of one hundred and
fifty miles, but it is still controversy
how far away thunder can be heard.
A French astronomer has made obServa-
tons on the subject, and he declares it
impossible for thunder to be heard at a
greater distance than ten miles. An
English meteorological has counted up
to one hundred and thirty seconds be-
tween the flash and the thunder, which
would give distance of twenty-seven
miles. W.
The lighthouse light at Cape de la
Have, France, is said to be the most
powerful in the world 1t is of 80, 009,-
600 to 100000 candle power. Both
| direct and alternating currents are
employed. In order to produce rapid
flashes, the revolving panels are placed
in float in mercury bath, thus di-
minishing the friction, and allowing it
to make complete revolution every
twenty seconds, while in ordinary
lighthouses at least four minutes are
required.
The telautograph, invented by
Elisha Gray, has many advantages
over any other means of rapid commu-
nication. The person sending the tel
autograph himself writes with pencil
point on a piece of paper at the trans
hitting instrument, and by means of a
wire attached to this pencil-poiut, he
writes at the same time exactly the
same thing in ink at the distant re-
ceiving office. Columns of figures,
drawings, plans, sketches and dia-
grams and maps may be sent in this
way, with no danger of mistake in
transmission, since the writer is at the
same time the transnlitter.
The Scientific American tells young
men how to become electrical engi-
neers 1t says that an educated me-
chanical engineer can become an cleo
trical engineer with few months Of
study. The electrical station of the
day is based for it's successful opera
ton largely on economy in the genera
ton and utilization of steam, SO the
student must make up his mind TO ac-
quire the fullest knowledge of steam
engineering and practice. When he
feels that he is thorough mechanical
and steam engineer it will be time for
him to think of completing his educa.
