MASTER MINDS DESCRIBE SOME
FEATURES OF THE EXPOSITION

position be noted for its display of all
modern electrical appliances and appa-
ratus, but u VIII show the numerous
historical features i'm the associat tions
OF electricity enabling the visitors TO
get clear ana perfect idea OF the lines
along which progress has been made
and Just how great this progress has
been UP 10 the present day. The Expo
sition Will show the accomplishments
or brilliant minds that have been at
work In the scientific and electrical
nelds, and the visitors may Judge for
themselves which one OF many men has
done most In the electrical field for hu.
manity.
Perhaps the general public is more
lamlliar with the application Of cleo
trlcity TO lighting than with the other
branches OF it's service mainly because
we come in closer touch with its oper-
ation and application TO this field
Many places are made nware Of the
progress made in arc lighting by the
substitution OF inclosed arc lamps for
ihe older style Of open lamp. These In.
closed lamps represent the modern type.
The idea Involved is 60 keep the electric
arc between the carbon points burning
IN an atmosphere which permits the
carbon TO be consumed at a slow rate
Thus the inclosed arc lamp VIII burn
for ten or more times the number of
hours that the older types will requir-
ing fewer men TO care for them.
In the field OF incandescent lighting
one must consider an industry that has
grown TO stupendous proportions This
lamp was given TO the world by Edison
in 1890 Both in the lamps and in the
machinery for the production OF the
nee essary current many improvements
have been made. In fact one has par
alieled the other. until today we have
apparatus which is surpassed in eff
cheney by no other industry. The i'm
candescent lighting of th~~grounds OF
the Pan-American Exposition viii be
spectacle unequaled by anything OF the
Kind the world has ever seen.
There viii De n storage battery ex
hibit at the Exposition that will thor
oughly portray the wonderful advance
ment made. and IL viii be evident 20 all
that many OF the obstacles found I'm this
branch Of electrical service have been
surmounted and that We are entering a
new and promising era in which The
storage battery win play an important
part.
II is but IA years since the first com I
inercial electric street railway was esS
tablished. but the progress has been so
great that city and country are now /,
connected by magnificently equipped /
electrically operated roads. To a GER I
tain extent this progress has revolu- /
tionized the methods of living. for the I
high speed attained enables people 10 4
live In suburban towns and reach the l
business centers with little loss of time /
The public has enjoyed the improve !
ments made In the operation OF cleo 1
trio railways. but has paid little at
tention TO the apparatus by which re-
suits most pleasing have been reached
Perhaps the progress has been so rapidj
hat il would have required a careful
student TO keep up with. the pace set,
and on this account the INTERROGATION
" the various clements will be clearly
brought cut, demonstrating that the
Ipplication OF electricity to the propul-
ion of cars, trains and vehicles forms
me of the most wonderful illustrations
# the utilization or electrical energy
In both the Electricity and Machinery
ections of the Exposition there viii be
many examples OF the utilization of
lectricity in the operation of machine I,
ools In this way IL will be demon
trated how electric motors and their
pplication have revolutionized the op-
ration of factories and this class OF
ools In many factories where belt
ng had been the only means of driving
hating and tools motors have taken
is place. resulting in increased eff
iency of both workmen and machine

he workmen and the production OF an
utput of higher class.
