pOHtoOuS, masked DatteT1eS or Searcn-
lights will be located upon the roofs
of the exhibition palaces; behind the
columns of the colonnades that en-
circle the courts and in recesses of
towers, domes and minarets indirect
or reflected light will be employed.
The thousands of lamps used in the
reflected lighting will not be seen but
their lights will be cast upon the
statuary, mural decorations, and ia
cades of the buildings. In the courts
and throughout the grounds will be
radiant groups of statnary.
The interior of the buildings will be
lighted with flame arcs and luminous
arcs 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
ulmns will be warm yellow in the
lower sections, while the upper Sec
tons will be a blush purple pro,lpc-
ing an artificial shadow in the light.
The walls behind the colonnades in
the grand court of honor, the Court OF
Sun and Stars, and in the great east
and west courts, will be decorated
with mural paintings which will be IL
Illuminated by electric globes placed in
lrecesses in the backs of the columns;
the lamps will not be visible from the
floors of the colonnades or from the
courts. These will be set in the col
umns at heights of ten, twenty and
thirty feet The illumination of the
paintings will be absolutely controlled
by changing the size of the light units
and the curvature of the mirrors that
will reflect the lights against the
walls. Kaleidoscope effects will be
obtained by introducing colored bulbs.
A special type of tubular lamp has
been developed for fluted columns,
the lamp and reflector being small
enough to go into flute of each col
umn
/ The method Of turning on the lights
at night will be original. At first the
visitor will notice myriads of little
jets of light throughout the exposition
where batteries of searchlights throw
| their rays against the jewels in the
towers and above the figures of the
stars around the Court of Sun and
Stars; then from behind the columns
| of the colonnades that line the walls
| of the buildings the light will break
out, flooding the mural decorations
with radiance; then ill come the
great white light throughout the expo
! sition, and finally scintillators an
4 chored six hundred yards off the es-
planade will direct their batteries of
colored lights throughout the exposi-
/ ton grounds. These scintillators will
| be manned by fifty or sixty men who
are drilled to handle the batteries Of
lights in much the same manner that
! artillerymen are drilled. THE effect"
says Mr.. Ryan. will be marvellous.
1 The batteries will go through evolu-
/ tons Of color, forming auroras in the
sky and over the exposition, that will
spread like a great lily. On clear
nights the shafts of light will be yisi-
BILE forty or fifty miles"
The shafts of colored light meet
ing in the heavens will produce mar
yelous effects, color painting with the
skies as canvas. But he who deals
with light rays obtains results far re-
moved from those attained by the art
list who works with pigments. The
reason is that the painter in mixing
his pigments is most frequently deal
ing with impure colors. Thee painter
takes a yellow pigment and blue
pigment, both of which are impure.
since the yellow contains a little bit
\ of green and the blue contains little
bit of green as well, and the result OBJ
! tanned is a green through the impurity
of both pigments. The artist who
deals in light, which is pure, finds
when he mixes yellow rays OF light
and blue rays of light that he gets
white, and SO it is that at San Fran
cisco men will paint pictures upon the
i clouds
