A total Encouragement of the system
of lightning conductors on st. Pauls
cathedral, says the London News, is
now virtually complete. 1t is interest
ing to learn from Killingworth Hedges,
the electrician under whose superin-
tendence the work has been carried
out, that the old idea that the erection
of lightning rod on the highest point
of structure protected an area all
round is quite illusory The safeguard
ed area was supposed to be the space
within circle whose radius was equal
to the height of the lightning rod. This
theory, we understand, is now discred-
tied, and the cathedral has been pro-
tected by a system of conductors, per-
pendicular and horizontal, comprising
over mile of cables, on which at
various prominent points are placed
about so "aigrettes groups of solid
copper spikes radiating upward, and
effectually connected at the base with
the cables.
E. q. Pope, western passenger agent
OF the Chesapeake and Ohio railway
at st. Louis, Mo-, has lately invented
an ingenious device, which consists of
second electric headlight" or
searchlight, mounted upon the roof of
cab of locomotive, pointing al
ways to the rear of the train, there
fore he calls it a "hind light" and the
chief object of the invention is to pro-
tect the hind end of the train from
being run into by any train that may
be following it. The hind light"
rests upon the roof of the cab, and is
attached to one end of lever about
eight feet long, and is steadied and
controlled by two parallel rods, and by
means of simple arrangement of
cylinders and compressed air can be
elevated six or seven feet above the
Roof of the cap or swung around at
right angles to either side of the cab.
Omaha capitalists propose to tunnel
the great continental divide, so miles
west of Denver, and II miles south of
Georgetown, and operate an electric
road through it. 1t will start at the
base about Ia miles from Grant and
terminate at the head waters of the
Snake river, will be 1000 feet long
and LOO feet deep. The object is to
facilitate mining operations. The tun-
mel will be built of sufficient size to
admit steam railroad train. and NAV
be utilized by some one of the great
transcontinental lines as a short cut.
The longest electric railway in the
world is to be built in Montana. The
proposed line is from Billings to Great
Falls, some 200 miles. and the plan is
to operate it entirely by electric power.
which is to be supplied from general
ing stations on the Missouri and yell
lowstone rivers. The road would have
a considerable traffic in coal. ores. and
other heavy freights. and would be the
nrst line with such traffic to be
worked by electricity.
Three lines of electric omnibuses.
intended to compete with the street
cars for patronage in all parts of Chi
cago, are projected. They will be
double decked. and will have seating
capacity for forty passengers. They
Will take on passengers at any corner
along the route until the seats are all
filled, and then the vehicles will be-
come expresses and will make no
more stops until the downtown dis.

The chief fire engineer of the New
Orleans U-a) department has figured
out that the relative cost as between
a three-horse hitch engine of the first
class and an electric power engine is
$50 month for the former and s27
Tor the same period for the latter.
These figures show clear gain of ss3
per month, and $500 per annum. in
round figures for the electric power
engine.
