Usefui In Many Ways on Stcamers
and shortens the Voyages,
Owing to the general use Of electricity
on board transatlantic steamers, mar.
veious economies Of labor and steam
are accomplished, and It Ii largely due
to the assistance Of the electric current
that the recent phenomenal record.
breaking runs were made. The cleo
trio installation on the steamers st.
Paul and ct. Louis represents the most
recent achievements Of the electrical
engineer. Nowhere else Ii the applica.
ton Of the current applied to such a
large range Of work. Here may be
seen almost every Important applica.
.tlon Of electricity, apart from the troll.
ley car and electric welding. The tele.
phone. the telegraph, the arc light, the
incandescent light, electric motors for
divers purposes, electric elevators.
search lights, electric cranes. call.bells
and numerous special devices are to be
found, all within the space Of 800 feet.
These numerous applications Of tho
electric current are described In an In.
tcrestlng article In Electrical Doings,
which treats particularly Of the steam.

Of the st. Louis IL almost Identical.

Of ten horse power each for the refrig'
Grating apparatus and ono Of eight
horse power for an electric elevator
There is also large organ operated BY
an electric motor. The vessel, Of
course, Ii provided with electric bells
and annunclators In profusion, while
wiring to the extent Of twenty miles Il
required for the lighting and motor cir
suits alone. Besides the electric search
lights there are also number Of por
table renectors, two and half feet Ia
diameter. each containing six lamps
Of thlrty-two candle power. which are
used In the hold.
Every electrical invention conducive
to comfort and perfection In navigation
may be found In this vessel. In from
Of the pilot house Ii an electric button
which blows the whistle. Within thu
pilot house IL another electrical con
trivancc which. In connection with 4
clock movement, sounds the whistle
automatically for ten seconds In every
minute during fogs. There ID also q

head and the port and starboard lights
Among the special devices arc two cleo
trical shaft revolution indicators, on'
connected to each shaft. and an cleo
trical rudder position Indicator. b.
