A FINE MINERAL DISPLAY.
MaryIand's Geological Exhibit mt the
Buffalo Exuosf4fou


BUFFALO, y Y, May I4-An aIIego--
ical picture representing the genius Of
geology uncovering the mineral wealth Of
Maryland occupies the upper part of the
east front of the Mines Building at the
Pan-American Exposition. Below this are
hung large maps Of the State of Mary
land. coIOred in various ways to repre-
sent geology, rainfall, and temperatures,
physiOgrap hic provinces. relative eleva-
tons and drainage areas. In the large
windows are exhibited large colored trans
pareHcies of Maryland scenery and stone
quarries and a series Of photo-m micro
graphs of sections of rock coIored as seen
under the microscope by polarized light
magnihed sixty diameters.
Nineteen frames of illustrations from
publications. topographic and geological
maps. scenes of quarries and coal mines
cover the remainder of the wall space
One Of the most striking objects is a pillar
of coal, three feet square and seven feet
high. weighing about three tons. This
cost the Consolidation Coal Company an
immense amount Of care and labor to cut
from the breast Of the Big yein. which
is fourteen feet thick, send it to the sur
face and ship it to Buffalo in one perfect
piece Seven smaller cubes represent
some others of Maryland's famous coal
seams.
The exhibits on the tables are mostly Of
economic value. At one end are shown
the building stones from the principal
Maryland quarries- Blocks of various
shapes represent the polished, hammered,
and rock surfaces OF Port Deposit, Cuff
ford and WaItersvilIe Woodstock, Eli
colt City. and Jones Falls GRANTEES Mar

the precious variety and PicroIite
Next comes less ornamental, but very
/ practical exhibit of the highway division
of the survey showing the various teses by

/ subjected at the laboratory in the
| Johns Hopkins University. The soils are
wei shown in a series Of glass jars and
| tubes. Seven tubes are arranged around
/ each soil specimen, each tube containing
/ its proper proportion of the constituents
l of the soil.

represented by its characteristic fossils
