GREATEST FAIR
WORLD EVER HELD

WORLD EVER HELD
Marvellous advances in the illumi
mating materials and methods will en-
able San Francisco to illuminate tn,
buildings of the Panama exposition
inside and out, in a way that would
have been physically impossible fiv,
or six years ago. The skilled illumi
mating engineer is to day able to pro
duce light effects undreamed of al
any of the former worlds expositions
The lighting of the exposition will
mark an epoch in the new and facin-
ating science of illumination. The en-
tire plan of Illumination is in charge
of Mr.. w. D'A. Ryan, director of H.
Elimination, who supervised the llu-
mination of the Hudson-F Fulton cele-
bration, of Niagara Falls, and who is
directing the illumination of the Pan
anna canal throughout its length to
the high seas on either side. In the
exposition there will not be single
article of lighting equipment that was
ever used be fore More than fifty
thousand dollars have been expended
in single line of experimentation,
the development of cut glass reflect
ors to be known as Jewels, for use
at the exposition. Most of these
have been made in Germany and the
result produced through their reflect
ed light will be among the superb
lighting effects.
The most striking effect in the illu-
mination plan lies in the fact that
there will be no dark shadows. At
night the exposition palaces with the
details Of their facades and statuary
will be seen as clearly as if by day.
Great paintings upon the walls, screen
Great paintings upon the walls,
screened by the colonades of the
courts, will appear in their true color
values as if by daylight, but with their
contrasts enhanced and intensified.
Perfect reflections of whole buildings
will be reproduced in the lagoons up
on the exposition grounds. In the
barber before the grounds batteries
of colored searchlights will throw
their rays against the towers and min
arets, pickings out the colors, and
against the rejecting jewels, which
will reflect and radiate shafts of COL
ored light throughout the exposition
city The zone of general ilumina-
ton will extend twice the height of
the talest exhibit palaces.
Both direct or indirect or reflected
lighting will be employed at the ex-
position. Mr.. Ryan is working in ac-
cord with Mr.. Jules Guerin, director
of color, an artist whose mark is as
popular in Europe as in America.
Most expositions appear too bright
and often the sightseer goes away
with tired eyes. Mr.. Guerin has con-
ceived marvellous color scheme |
through which there wifi be no dead |
white upon the exposition grounds |
Mr.. Ryan has planned that there will
be no glare and no dadk places or
blackshadows at night

the architecture and most of the finer
details would be lost through dark
shadows. The architectural splendors
of the exposition will be brought out
to the best possible advantage in both
form and color and maintaining the |
daylight perspective. By night the
exposition in all its details will be
