SAN FRANCISCO, April 16.-Marvel-
Gus advances in Illuminating mater
ials and methods will enable San
Francisco to illuminate the buildings
OF the Panama exposition, inside and
out in way that would have been
physically impossible five or six years
ago. The skilled Illuminating engi.
neer is today enabled to produce light
effects undreamed of at any of the
former worlds expositions.
The lighting of the exposition will
mark an epoch in the new and fas-
cinating science of illumination. The
entire plan of the illumination is in
charge of Mr.. W. D'A, Ryan, director
iof illumination, who supervised the IL
Elimination Of the Hudson-Fulton cele-
bration, of Niagara Falls, and who is
directing the illumination of the Pan
ANA canal throughout its length to the
high seas on either side. In the ex-
position there will not be a single
article of lighting equipment that was
ever used before. More than fifty
/, thousand dollars have been expended
In single line of experimentation
the development of cut glass reflec-
tors to be known as Jewels for use
at the exposition Most of these
have been made in Germany and the
results produced through their re-
Elected light will be among the superb
/ Lighting effects.
The most striking phase of the H.
Illumination 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,
screened by the colonnades of the
courts, will appear in their true color
values as if in 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
ltarbor before the grounds, batteries OF
/ colored searchlights will throw their
rays against the towers and minarets
picking out the colors, and against
the rejecting jewels, which will re
I fleet and radiate shafts of colored
light throughout the exposition city
The zone of general illumination will
extend twice the height of the tallest
exhibit palaces.
Both direct and indirect or reflect
Led lighting will be employed at the
EXPOSITION. Mr. Ryan is working in
accord with Mr.. Jules Guerin, director
4 of color, an artist whose work is as
popular in Europe as in America
Most expositions appear too bright
and often the sightseer goes away
4 with tired eyes. Mr.. Guerin has con
i ceived 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 OIL
black shadows at night.
Outline lighting will not be adopted
Although the contours of the buildings
is brought out by this method much Of
thC srtitultCStuIc anu luCSL OI Tilt
; finer details would be lost through
dark shadows. The architecture
splendors of the exposition will be
brought out to the best possible ad
vantage in both form and color ane
maintaining the daylight perspective
BY night the exposition in all its de
tails will be magnificent picture
All Guerin's colors, the burnt orange
yermilion, cerulean blue and gold O
the courts, the gold and blue of the
recesses of the towers, the vaa
friezes of red, yellow and blue the

domes and the copper-green minaret!
