in THE ELECTRICAL WORLD.

The stores Mt Holland, Mich, are
It by electric lights.
In all sections of New York Citv
great activity in underground construc-
ton has been shown during the past
year. both in building subways and lay
ing conduits.
The Lewiston & Auburn (Me.)
Street Railway Company, it is reported,
is TO adopt electricity rs it's motive
powcr'and that in the coming spring the
cars Will be operated by electric power.
"A Spanish noblcman has recently
had an electric plant installed ut his
country place, which will be used to
pillow his land with plows run by cleo
trlc motors: The power is generated
by water wheel of 20-horsc power, and
Is sent n distance of three miles.
"A Riverside (Cal.) man is reported
10 have arranged an electric frost alarm
which will be Il great convenience to
orange growers. 1t consists of an ac-
curatc dial thermometer, electrically
connected with Il bell and switch in such
a manner that it will cause the bell to
ring when any desired temperature is
reached.
line and cable, which is to connect Lon
don with Paris, has been completed. 1t
consists of two bronzcd wires, parallel
ana crossed at intervals, to diminish the
effects OF induction. There will also be
direct telephone communication be-
tween London and Marscillcs, and Lon
don and Rome.
Club men and others, who STAY out
late of nights and have difficulty in
finding the llcyholes of their doors. can
now take heart, for some genius has in
vented walking stick, in the head of
which is n tiny incandcsccnt lamp,
covered ordinarily by polished knob.
The power is applied by IL miniature
storage battery in the hollow of the
cane, and the light can be turned on at
Will. This instrument is called 1.-The
Club Mans Friend; or An Adjunct to
Jollity."
Electric lighting of theatcrs has be-
come quite general in some sections of
the country, and promises to become
universal, owing to its great mobility
over the old forms of lighting. One of
the most interesting pieces of work of
this kind, says the New York Times, is
that just finished at Hcrrmann's new
thcatcr in New York, where the appa-
ratus is of the most elaborate and com
plcte nature, so that by means of lights
OF different color and the judicious in
terpolation of rcsistanccs, lighting ef-
fccts of any shade or degree of briuiancy
can be secured by the "gas man" on tho
turning of Il single switch.
"A new departure in electric light
ing, and one which is certainly to be
most highly commended, says Modern
Light and Heat, has just been made by
the Pennsylvania railroad, which is
about to equip line of track, seven miles
IN length, with electric lights. The piece
OF track in question runs through n very
heavily populated district, and is one on
which, in times past, there have been
frequent accidents. 1t is fully believed
that the advent of the electric light will
prevent their recurrence, and should it
prove as successful an illpminant as is
expected, the wires will be extended to
cover much longer district.
1t is announced that the Mctropoli-
tan Street Railroad Company of Wash.
ington, ID. c., has decided to change the
entire equipment of its main line from
horse cars to storage battery cars. 1t 10
now building the first instalment of
cars and preparing to commence the To-
cation of an extensive power station at
Rock Creek, between Washington and
Georgetown, adjoining its present car
stables. About 10 cars will be required
on this line, and they will be put in OPP
Grafton, probably in lots of five as fast
as they can be gotten ready and as soon
rs the charging station is started. 1t is
expected the first cars will be running
i'll three or four months, and it is said
that the cost of the change to the COM
pany will be S50o,0 Engineer Mail
loux's motors and gearing will be used.
