BORGLUM TO CARVE
FROM HUGE PHOTOS
Shows Protector to Take Pic
lures 220 by 10 Feet
on Cliff.

Special Dispatch to THE NEW YORK HEnALo
STAMFORD, Conn.,, Nov. IA - Gutzon
Dorglum, the sculptor, demonstrated TO-
night at his country place light pro-
jector by which he intends to make
series of photogra phs 22o feet long and
10 feet high, sensitizing the face or
granite cliff and using 1t as his plate.
The photographs are TO be used In ia
cilitating the ssetching In or more than
1000 figures, each eighty-five feet high.
in his memorial to the Confederacy
which is to be carved on the northern
face Of Stone Mountain, granite mono
lith rising sheer from the countryside
fourteen miles east OF Atlanta. Ga. That
side of the mountain Is an almost per-
pendicular plane about 500 feet high
and 1900 feet long.
Mr. Borglum's plan is TO SEND ere"
of men down the side OF that clifr AT
night with several barrels OF nitrate OF
silver He will then place in the pro-
lection machine plate bearing pic
ture of the part of the group 10 be
carved upon that portion of the rocKf
surface which has been sensitized, a.ld
that picture will be projected upon the
remain most OF the night. thus making
time exposure. Several barrels of de-
veloper will then be applied to the rock.
After that the light of day and about
10000 gallons of water poured down the
face OF the cliff will complete the work
of making the photograph upon the
mountain side.
With the figures outlined by this pho-
tographic process Mr.. Borglum and his
assistants will be lowered over the ciiff
in cable elevators and begin the work
OF cutting the stone
Mr.. Borglum said he has devised this
scheme to overcome two big difficulties.
One is that of facilitating the speed OF
the preliminary sketches on the rock;
tho other Is a matter of perspective.
The face OF the stone slants backward
a few degrees and to that must be
added an angle of forty-fivo degrees
from which spectator in the park at
the foot OF the mountain would have
to look at the sculpture. The result OF
the combined angles would be a dis
tortion in the eye OF the spectator. To
overcome that Mr.. Borgum proposes TO
carve the figures In sufficient distortion
10 overcome the angle and present the
figures 10 the spectator in their true
proportions
That solution is arrived at by mount
ing the plate holder I'm the projection
machine upon a pivot. The plate then Is
inclined in the machine to such an angle
as to make the figures appear In normal
proportions from the park.
Mr.. Borgum proposes to carry this
method where convenience dictates by
sending men down the side OF the cliff
with paint and brushes to sketch In by
hand the projected figures.
T~,o ~ fha HIGHT s1rOieCtiOr
method OF obtaining his preliminary
sketches, Mr.. Borglum said. Is TO sur
vey the surface of the cliff and lay II
Off In squares, by means OF which the
figures would be traced to scale from
small pictures similarly marked off In
squares. That he pointed out. would
be a tedious and almost interminable
process.
The projection plant Is a gift to the
Stone Mountain undertaking by +. s.
Porter. manufactures OF Simplex high
intensity projectors used In motion pic
ture theaters. The machine at Mr..
Borglums place Is similar 20 the motion
picture machine, except that 1t is
larger and much more powerful. The
largest motion picture projectors are
designed to throw a shaft OF light TO
maximum of about $50 to 800 feet
In the demonstration here tonight
Mr.. Borglum's machine threw a shaft
for n distance OF 600 feet. where II
illumined woodlands and rocks with a
white screen twenty feet square as
central target. The screen caught por-
tions OF the equestrian figure Of Gen.
Robert u. Lee. who, with Jefferson
Davis, will be the leading figure OF the
vast army which Mr.. Borgium proposes
to carve.
The projection machine will be taken
to Stone Mountain next week for ex-
pertinent. Mr. Borglum said he expects
to begin cutting stone before next sum-
mer. Power plant. elevators and other
equipment have already been Installed.
