The Richmond palladium and sun-telegram. [volume] (Richmond, Ind.) 1907-1939, 1913-04-09

SAN FRANCISCO, April 9.-Mar-
Vicious advances in illuminating mater
| ials and methods will enable San
Francisco to illuminate the buildings
| of the Panama Exposition, inside and
out, in a way that would have been
physically impossible five or six years
| ago. The skilled Illuminating engineer
| is today enabled to produce light eff
| fects undreamed of at any of the for
mer worlds expositions.
The lighting of the exposition will
| mark an epoch in the new fascinating
science of illumination. The entire
plan of the illumination is in charge
of Mr.. w. D'A. Ryan, director of IL
| Elimination, who supervised the illu-
mination of the Hudson-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 expo
| sition there will not be a single acti-
Gle of lighting equipment that was ev
er used before. More than fifty thous-
and dollars have been expended in
single line of experimentation, the de-
Velopment Of cut glass reflectors to be
known as Jewels" for use at the ex-
position. Most of these have been
made in Germany and the results
produced through their reflected light
will be among the superb lighting eff
| fects.
| The most striking phase of 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
ed by the colonnades of the courts,
will appear in their true color values
as if in daylight, but with their con-
tracts enhanced and intensified. Per
feet reflections of while buildings will
be reproduced in the lagoons upon the
exposition grounds. In the harbor be-
fore the grounds batteries of colored
searchlights will throw their rays
against the towers and minarets, pick
ing out the colors, and against the re-
flecting Jewels, which will reflect and
radiate shafts of colored light through
out the exposition city. The zone of
general illumination will extend twice
the height of the allest exhibit pal
aces.
Both direct and indirect or reflected
lighting will be employed at the expo
sition. Mr. Ryan is working in accord
with Mr.. Jules Guerin, director of col
or, an artist whose work is as popular
in Europe as in America. Most exposi-
lions appear too bright and often the
sightseer goes away with tired eyes.
Mr.. Guerin has conceived a marvellous
color scheme through which there will
be no dead white upon the exposition
grounds. Mr.. Ryan has planned that
there will be no glare and no dark
places or black shadows at night.
Outline lighting will not be adopted.
Although the contours of the buildings
is brought out by this method much
of 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 ad-
vantage in both form and color main
tanning the daylight perspective. By
night the exposition in all it's details
will be magnificent picture. All Guer-
ms colors, the burnt orange, vermil-
ion, cerulean blue and gold of the
courts, the gold and blue of the re-
cesses of the towers, the vast frieZes
of red, yellow and blue, the red tiles
of the roofs, the golden domes and the
copper-green minarets will be seen at
night enhanced and glorifed.
There will be four principal sources
of light at the exposition. In the
= harbor some six hundred yards off the
exposition grounds will be great bat
teries of searchlights mounted upon
pontoons; masked batteries of search
lights will be located upon the roofs
of the exhibit palaces; behind the col
umns of the colonnades that encircles
the courts and in recesses of towers
domes and minarets indirect or re-
. f1ected light will be employed. The
thousands of lamps used in the reflect.
ed lighting will not be seen but their
lights will be case upon the statuary
mural decorations, and facades of the
buildings. In the courts and through
out the grounds will be radiant groups
of statuary
The interior of the buildings will be
lighted with flames arcs and luminous
: lacrs and at night the great windows
will shine out with their Nominations
The direct lighting will be the light
upon the facades and sides of the
: buildings. The light behind the col
: umns will be a warm yellow in the
lower sections, while the upper sec
tons, while the upper sections will be
blush purple producing an artificial
shadow in the light.
The walls behind the colonnades in
the grand court of honor, the Court
of Suns and Stars. and in the great
east and west courts, will be decorat
ed with mural paintings which will be
illuminated by electric globes placed
in recesses in the backs of the col
umns; the lamps will not be visible
from the floors of the colonnades OF
