IN THE ELgcra,cAL WORLD.

The post Office department. at Wash
ington is trying a mechanical letter
stamping machine operated by cleo
tricity.
Electricity is now being used in min
ing. for ventilating, pumping, lighting,
signaling. sub-surfnce hauling, hoist
ing. surface transportation undcrcut-
ting. drilling, channcling, blasting,
crushing, separating and clearing.
1t is reported that the Spanish gov
eminent has undertaken a considerable
extension of the telegraph system by
the construction OF several new lines
and the establishment of $50 new sta
tons. The telephone system is also to
be greatly extended.
"A pool table with electric push but
tons arranged in front of the pockets
has been put on the market When a
ball runs over push button an cleo
trio contact is made, and the play is re-
corded by an aununciator on the wall.
The score of the game is thus kept
automatically.
III the proper permission can be Sc
cured, it looks as though the managers
of a Swedish railroad would have the
honor OF first repli ling. on large
scale, steam railroads with electric
roads. A road is to be built between
Stockholm and DjursholIn. and the
work of cquipping it as an electric road
will be begun as soon as the right to do
SO has beed granted by the authorities.

has, after long deliberations. lasting
over the greater part of 1891, practical
ly decided to try the accumulation or
storage battery system on a large scale.
1t has been discussed from time to time
at their various deliberations, but this
last conclusion is very recent a Lon

Electricity in legitimate medical
practice is being more largely employed
than ever. One of the recent applica.
tons in this direction is for the treat.
ment of deafness. The apparatus for
this purpose com prises n battery. a belt,
an electric supporter on the belt and
shaped to rest on the ear. an opening
on one side to receive the ear. and con-
nections between the electrode and the
battery. This provides convenient
and efficient mode of receiving the cur
rent, which can be applied in finely
graduated strength.
Electric heating is the coming new
development in electrical science. and

by electricity. Not only that, but all
cooking may be done by the same

the new energy to heat and cook with.
but it has so many advantages. and can
be maintained under such perfect con-
troll. that the trifling difference in cost
over present methods will not be
thought Of.
Electricity as 4 tractivc agent, is, il
is said. about to be tried in this coun
try in such manner as will allow OF a
comparison with steam service over tho
same route. 1t is announced that the
Pennsylvania Railroad Co, which owns

by elec,ricitv--will build a trolley roat
from Jersey City to Newark. For NOR
than half the distance the line will ruI
across HackcnSack meadows ant
through unsettled districts, where TIT

system is capable will be pcrmissi bic
The most promising field for the cleo
trio motor is in towns where the use O
a steam motor is forbidden. and on tn
projected lihe electric traction may b
subjected to comparison with steat
power on the basis OF economy.
