. Rapid Transit. II.
The wants Of civilized man have in.
creased faster than his ability to supply
them, and every increase in speed has.
increased business in a greater ratio.
Fifty or sixty miles an hour has been
considered rapid-and the average rate.
On railroads is only about half that
but we are now on the eve Of a great
change Strength Of mechnism to en-
cure the strain, cost and safety are the
conditioning factors.
1t has been shown that with properly
constructed roads one may be safer at
sixty miles an hour than on poorly
constructed road at twenty miles. The
rate is but a small figure and with an
electric motor in place of the steam
locomotive there is great advantage
for speed in many ways; A five
hundred horse power motor can now
be made as readily as a hundred
horse power locomotive, and that
the former can run safety two
miles a minute there is no manner of
doubt E- 80 VI +. H.. -
1t is altogether probable that within
q year from this time electric trains
will be ran at this speed between Chi
5cago and st. Louis, and with as great
safety as with present express trains.
The completion of that road will prob
ably precipitate a rapid change in all
railroad work. 1t should be remem-
bered that the sudden adoption of such
a new method, which renders useless
the present appliances, would be ruin
GUS to most roads in the country; never
theless, the time may not be so distant
when all locomotives will have gone to
the dump, save here and there one in
a museum standing like an extinct
mastodon. For transporting mail and
express packages still other electric de-
vices, like Williams portelectric system.

ri. Perils in Electricity.
The introduction of electric lighting
is. thanks to the solicitude of the legis-
lature and the skill enlisted in the SER
vice of the board of trade, says London
Lancet, an industry which. it's magni-
tude considered, has been attended
hitherto with singularly little loss of life
and personal injury. The inquest held
upon the body of workman who had
met his death by incautiously ''short-
circuiting' lightning current. disclosed
no new and unsupported danger and
gave no occasion for regret except for
the human frailty which led a young
man to incur needless risk by neglect
ing the most elementary precautions in
the conduct of his work. 1t would seem
that in this case the paradox is true
that, if the electric lighting current We're
less dangerous than it is, people would
handle it with greater circumspection
than they do. A Ruhmkorf coil deals
a smart blow if inconsiderately touched,
and nobody does touch it inconsiderate-
ly, although it always, when in action,
presents numerous surfaces which are
highly charged with electricity. But a
lighting main is apt to kill, and is there
fore insulated with the greatest and
most effective care. Hence accidents
are rare. so rare that they cease to
make an impression, and a needless
workman manipulates the mains with
bare hands as if they were harmless

gloves would make him quite safe, as he
perfectly well knows, but he prefers to
take the small and incOnspicuOus risk.

The Light of the Future.

very few years the incandescent lamp
which we now regard as i'll many re
spects an almost perfect light, will be
regarded as a crude makeshift, which
mankind awaited itself Of while science
stood on the Threshold Of the discov
cry of the perfect luminant. Tesla has
! shown in his experiments, an idea
form Of electric lighting which woul6
transcend in luxury and convenience
our present system of electric lighting
by incandescent lamps as far as thu
latter transcends the oil lamps and tai
low dips used by our near ancestors
Every drawing room would become al
