IN The ELECTRICAL WORLD.

The use of electric headlight. for
locomotives Is increasing. BY 9, 500
candle light objects may be seen q mile
away on n straight track
"A Californian has invented a long.
distance telephone of very simple con-
struction with which he is confident he
can hold communication across the
continent or under the ocean.
Interesting experiments have been
made 10 demonstrate that the tides are

II recall" said an electrical invent
or. that about twenty years ago I had
one OF the largest electrical libraries in
the United States. 1t consisted OF five
volumes In looking over the Elec-
trical Review book catalogue. the other
day, noticed the titles of nearly four
hundred electrical books OF such is
the kingdom of progress"
The New York Recorder says that
in New York city about ten thousand
subscribers are connected by twenty
i've thousand miles of wire. and they
use the telephone over hundred thou
sand times day. A careful calcula-
ton shows that during the year over
four hundred and fifty million CONVEX
sations were carried on by telephone in
the United States
Mr.. A. Il, Holson, of Chicago, has
invented an apparatus by which RUM
way horses can be stopped by pressing
button connected with battery.
which Will give them an electric shock.
1t wasrecently tried in Chicago on n pair
of spirited horses which were frightened
into running by severe and unexpect-
ed blow with the whip. Although the
animals were going at terrific speed,
they came TO complete and immediate
standstill when the electricity was app
piled.
J Mr. Kelway. according to Indus
tries, has introduced an exceedingly
simple system of signaling at night. A
board Is provided with incandeScent
lamps arranged so that different sets
form different letters. II the letter "
Is wanted for instance, a key is pressed
/ which lights all the lamps which 90 to
/ form this letter and so on. The ma
chino can be worked like typewriter.
I Signaling by this means corresponds
/ with the use OF the black board in tho
daytime. but is. of course. much more
rapid. and at the same time more easily
'ollowed. IL is, of course, incompar-
ably more rapid than any system of
fash signaling, and is easy to read.
An English firm is introducing a
new form OF portable light, which is
operated by concealed storage bat
terry. This light is mounted on an or
namental brass tripod, and Il is stated
that one charge of the battery. con-
tanned in the stand or tripod is suf-
ficient for running sixteen candle
/ power lamp for eight hours. The bat
/ terry is started by COMPRISING an india
rubber ball, the pressure of the air in
the acid chamber causing the fluid to
rise in all the cells of the series. When
not in use the liquid is pumped out of
( the reservoir by allowing the air to es-
! cape.
The application OF electricity TO

I increasing very rapidly, and it is safe
/ TO predict that it will become general
in the near future. Very frequently
mines are situated but short distances
from water powers, and the transmits
! sion Of current becomes very simple
matter. The saving in cost OF opera
! ton over that where coal is used is
/ simply enormous. Many mines which
| IL has heretofore been impossible to
work, owing to the cost OF coal and its
/ transportation, are now. by applying
/ electricity for motive power and other
/ purposes, operated, and at very salts

value Of these properties will add a
very considerable sum TO the aggregate
wealth Of the country.
