ardens was surmounted by nearly two hundred
incandescent filament search-lights. Light was everywhere, either
varying in color into a harmonious scene or changing in light and shadow
to mold the architecture and sculpture. The enormous glass dome of the
Palace of Horticulture was converted into an astronomical sphere by
projecting images upon it in such a manner that spots of light revolved;
rings and comets which appeared at the horizon passed on their way
through the heavens, changing in color and disappearing again at the
horizon. All these effects and many more were mirrored in the waters of
the lagoons and the whole was a Wonderland indeed.

The scintillator consisted of 48 arc search-lights three feet in
diameter totaling 2,600,000,000 beam candle-power. The lighting units
were equipped with colored screens and the beams which radiated upward
were supplied with an artificial fog by means of steam generated by a
modern express locomotive. The latter was so arranged that the wheels
could be driven at a speed of sixty miles per hour under brake, thereby
emitting great volumes of steam and smoke, which when illuminated with
various colors produced a magnificent spectacle. Over three hundred
scintillator effects were worked out and this feature of fireless
fireworks was widely varied. The aurora borealis and other effects
created by this battery of search-lights extended for many miles. The
many effects regularly available were augmented on special occasions and
it is safe to state that this apparatus built upon a huge scale provided
a flexibility of fireless fireworks never attained even with small-scale
devices.

The lighting of the exposition can barely be touched upon in a few
paragraphs and it would be difficult to describe in words even if space
were unlimited. It represented the power of light to beautify and to
awe. It showed the feebleness of the decorator's media in comparison
with light pulsating with life. It consisted of a great variety of
direct, masked, concealed, and projected effects, but these were blended
harmoniously with one another and with the decorative and architectural
details of the structures. It was a crowning achievement of a century of
public lighting which began with Murdock's initial display of a hundred
flickering gas-jets. It demonstrated the powers of science in the
production of light and of genius and imagination in the utilization of
light. It was a silent but pulsating display o
