trio lighting plant to be run by the city.
There are in Philadelphia over 5000
buildings lighted by electricity. So far
the industries have not lost dollar
from fires caused by the wires.
An invalid's chair propelled by cleo
tricity is among the great novelties
The battery is capable of propelling the
chair over an ordinary road for nine
hours at the rate of six miles an hour.
Interest in the proposed cable be-
tween Australia and Vancouver is on
the increase. If laid, the cable will be
1900 miles long, and will cost 50, 600, 600,
on which the British Government will
guarantee per cent. dividend.
The term electrical was first EN-.
ployed in 1900 by DR.. Gilbert, to desig-
nate the attraction which amber and
other substances of Its class exhibit
when rubbed and presented to light
bodies, such as bits Of pith or paper.
Travellers who assembled Pixies Peak
frequently passed through electric
storms. During the storm each snow
fake as it touched the back of a
mule discharged q spark, and electric
sparks were discharged from the finger
tips
The mills in this section are quite
generally adopting the new electric APP
pliance for quickly stopping engines and
water wheels in case of accident The
pressing of any one of number of but
tons distributed near the moving ma
chinery will shut down the entire mill
at once.-Boston Herald.
"A leakage Of electricity at Detroit,
Mich, recently, was the cause of a
laughable sight The current became
connected with the iron steps of the
Lyceum theater, and the genu-fexions
of the people who passed over the
steps were as amusing to the specta-
tors as they were surprising to the per-
formers.
x, An idea of the profits in electricity
is afforded by the statement that the
Thomson Houston Company for the first
nine months of the fiscal year shows an
increase of business over last year of
So, 226, sos. Its profits for this period
over expenses were 81, 631, 715, an increase
of 1886, 452. The company's net profits

The large proportion that the cost
of platinum bears to the cost of incan-
descent lamps is shown by the following
figures: 1t is estimated that during the
year 1891 there will be sold about 10,
900, 900 16-candle power lamps. To man.
ufacture these lamps will require 1885,
600 ounces of platinum, which will cost
about S2,000.000 which is one-third of
the sum the lamps will sell for. Tho
discoverer or inventor of some substi-
tute for platinum will make a fortune,
To find out the amount of slack Civ
en- to electrical cables as deposited in
the ocean at the time of paying out,
Messrs. Siemens Brothers are using a
steel piano wire, paid out Simultaneous
ly, with tension sufficient to make it
taut over sea-bottom. BY mechanism
on board, which measures the rate of
paying out cable and wire the necessary
slackness in the cable can be determin-
ed and constantly verified, thus avoid
ing all unnecessary slackness, and saw
ing large sums of money.
The enthusiasts who predict that

ness lively on the canals are a little too
fast They forget that the fact that
prevented the introduction of steam
canal boats was that the wash of such
boats destroyed the banks of the canal
much more rapidly than boats lowed in
the old way. So far the cable appears
to be the only practicable one of modern
methods for propelling the boats, and
this, while it works well for the draw
ing of street cars, has not yet been suf-
fcently developed to make It CONNER
cially practicable for use on canals.
There is now being perfected in this
city an electric tricycle., which promises
great things The tricycle. is made pos
sible by a recently invented motor,
which weight for weight and bulk for
bulk is about twice as powerful as those
of the old models. The machine has
now reached point where it can be run
for distance of from fifty to sixty miles
without the storage battery, which fur
nishes the current, being recharged.
Those interested confidently predict that
when the machine is placed upon the
market it will be provided with a bat
terry powerful enough to propel the ma
chine for a distance of at least one hun
dred miles. The tricycle. will probably
