MARYLAND'S EXHIBIT.
Geological Survey Makes Showing of the
States Resources at Buffalo,

STATES resources at Buffalo.
BUFFALO, n. Y, May IA. - The
Maryland commissioners recently de-
cided that the Maryland geological
survey could make the best showing
of the resources of the State, and DIR.
W. Bullock Clark, State Geologist,
was authorized to prepare the exhibit
shown in the mines building.
An categorical picture representing
the genius of geology uncovering the
mineral wealth of Maryland occupies
the upper part of the east front Of the
building. Below this are hung large
maps of the State cOlored in various
ways to represent geology, rainfall
and temperatures, photographic
provinces, relative elevations and
drainage areas. In the large windows
are exhibited large colored transpar-
encies of Maryland scenery and stone
quarries and series of photo-micro-
graphs of sections of rocks colored as
seen under the microscopes by polar
lied light magnified 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 pillar of coal,
three 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 rep
resent some Others of Maryland's IA
nous coal seams.
The exhibits on the tables are most
ly of economic value. At one end are
shown the building stones from the
principal Maryland quarries, blocks
OF various shapes represent the pol
ished hammered and rock surfaces of
Port Deposit, Guifford and Walters
vile, Woodstock, Ellicott City and
James Falls GRANTEES. Marble from
the Beaver Dam quarries and the fa-
nous Seneca red sandstone and Shen-
andoah limestone are shown. This
is backed by the exhibits of the Mary
land slate companies-rough blocks
and dressed slabs, modern neatly
trimmed roofing states and states
which have served on roofs for over a
hundred years. The ornamental
stones are represented by collection
of polished slabs of variegated mar
bic. Potomac conglomerate and a
beautiful series of serpentines includ-
ing the precious variety and picrolite.
Next comes a less ornamental but
very practical exhibit of the highway
division of the survey showing vari-
, GUS tests by specimen and photo
graphs of machinery, to which stone,
brick and cement are subjected at the
laboratory in the Johns Hopkins
University. The soils are we'll shown
in series of glass jars and tubes.
Seven tubes are arranged around
each soil specimen, each tube con-
tanning its proper proportion of the
constituents of the soil.
Clays-labeled with their localities
and operties-building and mould
ing sands, kaOlins, ground flints and
marls are shown in glass. Under til e
table on series of steps and lighted
by electricity are the clay products,
enameled brick, fire brick, ornamen-
| tai and common brick, sewer pipe,
stove lining, crockery. tiles and terra
Gotta, some glazed, some unglazed, of
| all shades from bright red to white.
These make very attractive display
and will represent the great richness
and variety of Maryland's clays.
Installed in four plate glass cases is
very complete, systematic geologi-
cal collection. The oldest known
rocks are represented by contorted,
faulted and metamorphosed rock
specimens with ores of copper, iron,
lead and gold. Each age is represent
ed by its characteristic fossils-from
the Cambrian trilobites to the ele-
plants tooth of the Pleistocene with
such minerals and ores as occur,
placed in their proper horizons.
A complete set of the publications
of the geological survey, consisting OF
reports and atlas sheets, completes
the display indoors. Outside the
buildings are the larger pieces of terra
Gotta and slate.
