IN THE ELECTRICAL WORLD.

"A trolley railroad running for fifty
miles along country highways, and
connecting six Indiana towns with
Chicago, is soon to be built 1t will be
the longest trolley road in Indiana, and
one of the longest in the country.
An electrograph for marking linen
indelibly was shown to the Royal So
ciety lately. The fabric is damped and
current passed for. two seconds from
a silver die, carrying silver into the
fabric wherever it touches; the current
is then reversed for three seconds, re-
ducing the metal; the result is that
metallic silver is deposited on the tis-
sue.
The amount of capital engaged in
the electrical business, not including
telegraphy, is estimated as follows:
England, s1O0, oOO, 900; France, $50, OOO,-
900, 900; Germany, 5000, 000, 600; Austria,
Italy, Spain and Switzerland, $50. OO0,-
600; Russia, Sweden, Norway and DEN
mark, $50, 0Oo, 900; Canada and other
American countries, $500, 900, 900, max
ing a total of about S6Se, OOO, 900 in Eu-
rope and $500, 900, 900 in America.
AT the second trial of electricity
as a motive power on the Nantasket
Beach division of the New York, New
Haven and Hartford railroad, June 2l,
an average speed of so miles an hour
was reached in a three mile straight
run. Another electric locomotive was
attached to train of three passenger
coaches, and heavy steam locomotive
weighing over IT'S tons and easily
moved at the rate of speed of steam
locomotive. The starting and stop
ping was especially prompt.
Frank E. Grover, foreman of the
Rochester Gas and Electric Co., few
days ago received a shock of nearly
5000 volts of electricity and was re-
suscitated in about IS minutes. The
remedy employed in reviving Grover
was discovered by DIR. d'Arsonval, a
French scientist, in 1887. 1t consists
in restoring artificial respiration by
rhythmic movements of the arms and
pressure of the chest. DIR. dArson-
vaPs system was successfully ap-
piled in restoring to life James z. Cut
Ter, who was struck apparently dead
by an electric shock of 1900 volts in
Pittsfeld, Mass, on November 81 last.
One of the wonderful" inventions
connected with the telegraph and tel
ephone is that of an Illinois genius,
who is said to have perfected and in
vented an electric camera, which can
be attached to an electric circuit-such
as telegraph or telephone-and which
will reproduce images of the persons
speaking or communicating with each
other, thus enabling parents to see
their children, friends see friends,
even though a continent intervenes.
So perfect is the action of this electric
camera $50 it is said) that every move
ment and even changes in facial ex-
preston are faithfully show.
The Baltimore & Lehigh railroad,
which runs from that city to Delta,
Pa, will probably be the first road to
substitute electricity for steam as a
motive power. The Baltimore & Ohio
railroad will use only electric locomo-
tives in its tunnels, but the Baltimore
& Lehigh Co. contemplates using them
over the entire line. Estimates of the
cost of electrical power are now before
the executive committee of the COM
pany. The road crosses the Gunpow
der river and other streams which can
be utilized for water power to operate
the electrical supply stations.
I'm a recent lecture Lord Rayleigb
used as illustrations some photographs
he made three years ago of bursting
soap films. Photography gives the fol
lowing account: Each was taken by
the light of an electric flash lasting
less than one-millionth of a second.
The soap films were broken by means
of letting bullet, wetted with alco.
hol, fall through them; dry bullet
would go clean through them, per.
haps, dozen times without breaking
them The greatest difficulty in the
work was in the mechanical arrange
ments, to so time the flash that il
should occur just as the bullet had
passed through the film. The photo
graphs were good ones, showing the
falling bullet, and the torn and thick
ened edges of the broken film, as well
as. some little attached filaments OF
liquid beads of soap solution"
