Diggings.
Special Dispatch to The Star.


CHICAGO, May IT NA.N.A.)-The
life story of the diamond, the gem of
gems" will be presented to Chicago
Worlds Fair viewers by a three -storied
working model Of a diamond mine of
the fabulouSly rich Kimberley district
in Africa. The production will be
housed on three floors of the jewelry
pavilion of the general exhibits group
and will be the contribution of the Chi
cago Jewelry Association in co-opera-
ton with the Diamond Syndicate of
London, England.
Marion Mercer, representing the Chi
cago Jewelry Association, Is on his way
to London to confer with the Diamond
Syndicate officials about details of the
exhibit. After the Worlds Fair the
diamond mine model will be taken to
the Museum of Science and Industry
to become a permanent part Of that
institution.
Describes Exhibit.
Alfred C. Martin, a member of the
staff of the applied science and indus
try division of the exposition's exhibit
department, outlining the scope and
operations Of the diamond mine ex-
hibit. said:
"On entering the first floor the Wis
itors will see the underground opera
tions of the mining plant-the main
haulage way with its timbered roof,
narrow tracks and cars transporting
the precious ore, natives drilling in the
blue clay in which the diamonds are
found and the loading and hoisting of
the blue ground as it Is called. Typi-
cal mine cars will carry visitors through
the lower levels of the mine.
"A unique feature will be the illusion
of rapidly receding walls, moving in the
opposite direction from the cars, giving
the impression of speed and Travelled
distance. Each train, according to the
plans. will consist of two cars, capable
of carrying IS passengers.
Leaving the mine cars, visitors will
enter a full-size Kimberley hoist and
be lifted to the top of the shaft. Here,
again, by the use Of ingenious lighting
effect, dripping water and wind cur
rents, there will be produced an illusion
of being hoisted thousands of feet
through the earth at high speed.
Mill Is Also Planned.
"At the surface will be found a typ
ical compound, the high-fenced village
for housing the native miners and sur
face workmen and a group of native
huts. 1t is hoped that native miners
will be brought here from Africa. The
compound will stand at the brink of the
famous Kimberley pipe-800 feet wide
which will be represented by means
of huge diorama."
At the surface the visitors will enter
a mill and observe how raw diamonds
are recovered from the blue ground, or
ore.
"A very interesting part of the dis
play will be reproduction of street Of
old Amsterdam, Holland, which is the
diamond-cutting center of the world.
Here will be shown the quaint shops
and diamond cutters at work.
"The industrial uses Of the diamond
will be displayed-a full-size diamond
rock drill cutting a core in a solid
cement block; the cutting of granite
with diamond-tooth saw; wire-draw-
ing by means of diamond dies and other
operations.
$50 far as possible visitors win be
allowed to operate much Of the appa-
ratus themselves"
