crset county. obtained vertical sec
ton of a portion of the Lower Coal
Measures. As this part of the State
has been until quite recently, shut out
from Investigation, ! presumed that
this scale would be interesting and |
respectfully supmlt it.
The section was obtained from recent
coal explorations, near the village OF
Garrett on the Pittsburg and Connels-
Vile Railroad Atthis place the Serial
Conglomerate Is Very clearl y developed
rising gently westward on the eastern
flank Of Negro Mountain.
Negro Mountain, or rather the an
ticIinaI bearing this name, plows up
the midie Of the first great basin dlvl-
ding it at this place into two shallow
troughs having their greatest depth
of Coal Measures at Meyers Mills and
Bear creek, the whole lying between
the Allegheny Moutaintain on the east
and Laurel Hill on the west
Over the back Of Negro mountain the
Coal Measures and Conglomerate have
been swept away, leaving uncovered
the red back ofthe huge anticllnaI.
Castlcmans' river cuts deeply across
the Negro Mountain anticlinal, IN
folding natural geological section,
which has been further elaborated by
the railroad cuttings along It's northern
bank, the whole aii'ording unusual
facilities for studying Formations NJ
and XII with the posture and stra-
tigraphv of the coal Measures shoreing
on either flank.
Beginning in the railroad cutting
Immediately west Of Garrett station the
Serial Conglomerate can be studied up
to its floor. In this cutting thin
seam of impure coal has been brought
to light. 1t also exhibits 4 rather un-
usual plunge of the strata eastward,
carrying the measures down 800 feetin
three quarters of mile with this eX-
ception the measures exist under very
gentle dips.
The Conglomerate, in its lnechan-
ical structure and general appearance,
resembles Very closely Broad Top and
CIearfcld. did not obtain its total
thickness, but examined over 800 feet
of it, which indicates a greater depth
than at Broad Top.
The floor line is distinctly marked
in bold cliff outcrop, 10 feet deep, of
rather massive cong Iomerate, slashed
with cleavage planes.
On this rests a belt composed at its
base, Of thin plates Of sandstone grad
uating into shales and black slate as it
approaches the (A) coal seam. The
division has been terraced with flat
slope, from the brow of the Conglom-
crate to the coal seam, profiling the two
horizons very distinctly.
The first coal scam rests on a thin
floor of fire ebay. The coal bed has two
benches the lower, IS inches thick,
is an impure camel coal inclining to
block structure; the upperis a medium
quality of semi bitnminous coal with
the welI-marked coIumnor structure
peculiar to the Allegheny Goals,

The coal IN tins bed Is columnar IN
structure with plates OF mineral char
coal disseminated. In structure and
quality 1t IS closely associated with
the best Clealtield coal. 1t will be
found a superior fuel for IRON working.
The third seam (C) Is all pure eX-
ceIlent coal; but as the bed IS high
IN the measures and does not occupy
a WIDE area IN a horton OF the field IT.
