BUREAU OF MINES
PLANS EXHIBIT AT
PACIFIC EXPOSITION
Aim to Bring General Public
to Realization of Mining
Industry's Meaning and
Magnitude,

The United States Bureau of Mines is
manning q comprehensive exhibit at the
panama-Paciic Exposition.
In arranging the exhibit the bureau has
had in mind not only the value of in
terestng those engaged in the various
mining and metallurgical industries but
also the education of the general public
TO a better knowledge of the magnitude
of these industries and to the efforts
which are honestly being made by the
miners and mine operators, with the as
sistance of the Bureau of Mines looking
toward more safe conduct of mining
and a more efficient utilization of the
products of the mines after they are won
from the earth.
The bureaus exhibit Is located in the
Palace of Mines and Metallurgy. An au-
tomato duplex projecting machine will
continuously show lantern slides illus
trative of the activities of the bureau and
simultaneously give descriptions of the
lantern slides.
Nearby will be shown the layout of a
model hospital. including a receiving
room, wardroom and operating room,
fully equipped for demonstration by the
United States Marine Hospital Service;
plso a model of change and washhouse,
another welfare feature which is being
installed at modern mining and metal
lurgical operations. a plan of an ideal
mining town will be shown.
Ffrst-aid demonstrations will be given
frequently. An air of reality will be lent
20 tho demonstration by the removal of
apparently injured men from the exhibit
ton mine beneath the building by helmet
and rescue crews.
A complete display of rescue appara-
tus and safety lamps will be given in
a glass smoke room. Tests of safety
lamps will be made. showing their ten
dency, under unfavorable conditions to
ignite explosive gas and also showing
methods of testing for explosive gas by
means of their caps. An exhibit of the
physical and chemical characteristics and
constituents of explosives is being ar
ranged.
Visitors going through the exhibition
mine will regain the surface through the
radium booth. in which actual radium
emanations will be shown. Surround
ing this radium booth there will be
complete exhibits of the various radium
ores and of radium products. The metal
lurgy of various products will be shown
by comprehensive exhibit.
The opportunity for increased efficiency
in the use of fuels will be demonstrated
by device showing the proportlonate
amounts of fuels which go to make up
the various losses incident to consump-
ZION in comparison with that which ulti-
mately goes to useful purposes. Typical
analyses OF coal from the various fields
will be shown by models and samples, as
will also the yield of coke and by-products
obtained by various coking processes. 1t
is expected to show smoke-preventing
and smoke-producing methods of stoking
by means of an ingenious motion-picture
device.
An officer of the bureau will give his
whole attention to visitors. Copies of
the bureaus publications will be available
In hn
he particularly interested.
This exhibit, in connection with the ex-
hibition mine Immediately beneath the
bureaus space, should be interesting and
instructive to those engaged in the min
inS industry and to the general public,
