MARYLAND AT BUFFALO.
4 Fine Showing to BE Made by the
State Geological Survey.

BUFFALO. y. Y, May 9.-The Mary
land Geological Survey, in its exhibit at
the Pan-Americau Exposition at the
Mines Building is making a good show
ing Of tie resources of the State
An lIlegOTiCal picture representing the
genius Of geology uuC0veriuE the mineral
wealth of Maryland occupies the upper
part Of the east front of the building. Be
low this are hung large maps of the State,
colored in various ways to represent ge-
Ology- rainfall and ternpera lures, physio-
graphic provinces, relative elevations. and
drainage areas. In the large windows are
exhibited large coIored transparencies Of
Maryland scenery and stone quaTries and
a series Of acknowledgements of sections
of rock COIored. as seen under the micro
scope by poIarized light magnified sixty
diameters.
Nineteen frames Of illustrations from
publications, topographic and geological
maps. scenes of quaTries. 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 vein, which
is fourteen feet thick, send it to the sur
face and ship it to Buffalo in one per
feet piece Seven smaller cubes repre-
sent others Of MaryIand'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, Gull
