FLYING BIZ ELECTRICITY.
1t is now generally believed that the dis
| oovery of q system of artificial flight capa-
| bic of practical application is only a ques-
ton of time. It is also generally conceded
| by those who have carefully Investigated
| the subject that the airship of the future
will be propelled by electricity. Professor
Trowbridge, in a recent article on the sub
| iect, shows the directions in which the So
luton of the problem may possibly be
| found. OF the two methods suggested, one
| is the so-called telpherage system, used in
England for the purpose of transporting
small packages on a kind of aerial railway.
An electric motor runs on species of ee-
waited railway at great speed, and since the
railway can be practically an air line, the
| serious objections of deep cuttings, tunnel
ing and sharp curves can be avoided. An
other mode of aerial locomotion is the en-
plcyment of airships. a suitable balloon
could be made and provided With an cleo
trio motor, properly fitted with screws,
vanes and rudder, and q powerful current
could be led to the motor by means OF troll
ley wires, which slip, or the end of which
run along elevated wires, such
double trolley electric railroads.
Such an airship would be equivalent to an
aerial electric railway line, with this ad
vantage, however, that it could travel

stability of roadway or Limitations of curves
or gradients Another direction in which
continued improvements might open out
new possibilities of flying by means of cleo
tricity is the production of a comparatively
light storage battery, With this, and re-
ductiOn in the weight of the electric motor,
far beyond what we now conceive to be pos
sible, an appreciate stride will have been
taken toward the solution of one of the
leading problems of the age-fight by cleo
trio motive power.
ELECTRICAL TREATMENT OF DEAFNESS.
The extent to which electricity is being
used in legitimate medical practice is rapid
~ on the increase, and many of the new
devices for applying it have distinct merit
A recently invented apparatus for the cure
of deafness comprises battery, belt, an
electrode supported on the belt, and shaped
to rest on the ear, an opening on one side to
receive the ear, and connections between
the electrode and the battery. This pro-
vides convenient and efficient mode of
receiving the current, which can be ap-
piled in currents of finely-graduated
strength.
OF USE TO DENTISTS.
Dentistry owes much to electricity for
having largely added to its possibilities in
the way of skillful and scientific practice
1t is found that many of the flaws which
mark incipient decay in teeth are so minute
as to be invisible in ordinary light. The
importance OF being able to detect these
minute and tell-tale indications before seri-
Gus mischief has been worked by decay is
evident, and for means of accomplishing
this, the dentist has had recourse to the
electric light. BY this means the operator
is enabled TO explore with thoroughness
every corner of the mouth, and to instantly
perceive the slightest shade of change from
the normal color of the teeth.
LIGHTS FOR A SUGAR PLANTATION.
One of the greatest enemies of the sugar
planter is darkness, or the imperfect light
in which most of the operations incidental
in the night work of taking off, his crop
are necessarily carried on. In the boiling
house." where the juice of the cane is boiled
down TO sugar, the overseer keeps watch
and ward day and night, knowing that 1.-The
relaxes his watchfulness, even for mo-
ment, the negro laborers will promptly take
advantage OF the chance and fill their bas-
kets and pans with sugar or boiling
''liquor'' and the estate will suffer By that
amount.
AL this strain on the resources of a sugar
estate is to be removed by the introduction
OF electricity. The enterprisine proprietor
Of down-South plantation is the first to
realize the Importance of this weighty fac |
tor, and ne is installing plan which will !
give him light wherever he wants it. /,
Twenty-Five lamps will be used for lighting |
the sugar house and the cane field, and the |
works" will be as light as day.
IMPROVEMENTS IN RAILRoApING.
1t IS of interest to many cities now on the |
eve of establishing z system of rapid transit |
the best modern practice to note |
the changes which recent experience on the |
London electric line has suggested as de- |
'irable for adoption on the new Central |
London railway, which is also to be run by |
electricity.
The tunnel, which will pass under the
IS formerly, will be II feet inches in dit
imeter, instead Of 10 feet. This will give |
anger and more comfortable cars The
rain will carry $50 seated passengers, and
viii run on three-minute time, instead of |
100 passengers on our-aud-a-half-minute |
line, as on the present road.
The strange feature in the present road of
'unnilg the large elevators at the stations |
1y hydraulic pressure, transmitted throush |
niles of pipes from the generating station,
will probably be changed in the new road. |
Tators will be used An American electro |
ian, now in England, speaks with aston
shmeut of this anomaly.
He SAYS that to an American so accus- l
omed to electric elevators it seems extraor-
