OF surveying wrecks. for seinin9 fish,

in fact, every kind of submarine work
that calls for the services of diver.
Hampton Roads, Va, is rapidly BE-
coming encircled with electricity. Old
Point Hampton. Newport News. Nor
folk and Portsmouth are all lighted by
electricity, and as soon as few miss
ing links arc supplied the electric
chain of illumination will entirely en-
circle that wonderful body of water.
The great feature Of the recent elec-
tric light convention At St Louis. at
least 50 far as popular estimation is
concerned, was the lecture of Nikola
T. ~-ksAN
surprising experiments in electric light
productions were shown. Tesla is q
genius or luminary of the first order in
the galaxy of modern electricity.
-Pope's theater in St Louis. it ap-
pears. can boast Of convenience which
might be adopted with profit by thea
ters generally. In inaugurating the

abling those attending the performances
to be be called quickly in case Of peces-
sity. BY leaving their seat numbers in

diately.
I'm . paper in relation to the electric
Transmission of power, read by DR.
Louis Bell at the St Louis electric light
convention. tho doctor stated that the
foreign experiments of long distance
transmission were not reliable. and
were of no practical value. rs they had
been clumsily conducted Many. Of tho
recent Inventions in this line, which
are now attracting attention abroad, he
pronounced TO be adaptations OF the
motors of Thomson and Tesla.

Is deeply interested in the system Of
distributing mail over the street car
lines recently inaugurated in St Louis

claimed, there is no reason why 1t could
not be put into effect in Denver At IN
early day.
MIR. Siemens, in . recent lecture be-
for e the Royal institution Of London,
described . very interesting electrical
furnace for the manufacture OF horse
shoe nails It consists Of . huge core
of carbon made incadescent by . large
current of low voltage; the core is hol-
low, and is embedded in sand to prevent
the escape of the heat; the iron rod to
be heated is passed slowly through this
core. becoming red hit instantly. the
heat being regulated BY the speed with
which it was passed through II Is said

pering springs, and was also used for
heating rivet& It has the great ad-
vantage of being easily manipulated
and being quite portable.
