For one who has the time to spare,
nothing would pay better than few
hours spent ut the Electric Exhibition,
under the management of the Franklin
Institute, now being held ut the corner
of Lancaster avenue and Thirty. second
street, Philadelphia. The building,
which was built for the purpose, occu
pies an entire block, and . portion OF
the old Pennsylvania r. X. depot on
the other side Of the street, which l.
connected by q bridge that is extended
from the east balcony of the mall /
building.
The exterior of tho building at night
Is ablaze with hundreds OF tncan-
descent lamps strung along the sides, |
turning night almost into day. In thel
north rest tower is placed the great de-
tector, which will be used in naval war
fare to make visible the operations OF
the enemy at night, and to discover the
approach of an engine Of destruction
upon the surface Of the water. The
| light Of this detector Is 10000 candle
power, and being enclosed in projeo-
tor fitted with reflector and lens, will
throw q ray Of light, too bright for the
eye to endure, two miles across the city.
The interior Of the building knows no
shadow, and the most brilliant specta-
Gle of all is the main arched hall, the
high curved roof studded with arc
lights, while others are arranged along
the sides and among the exhibits. In
the centre Of the building is the great
fountain, throwing its spray high up
into the air, which is made beautiful at
night by throwing different colored
lights upon 1t.
The first thing one sees on entering
liza the bronze statue of Edison, the
great investor of the age, which is IL
lumiated by a circle of electric lights.
The statue is the work Of Rupert
Schmid, whose time and labor hal
brought to the front this masterpiece ol
r lart.
Edison's display has been made con
spicuous by lofty cone, covered witt
sparkling substance and studded will
lcountless incandescent lamps. Tn
