one or two bowlders were seen, but they are very rare. These bowlders
I had supposed to be dropped by floating ice, since no other drift material
was found upon the top, or clinging to the slopes, of the ridge. At other
places in the valley of the Moxahala, are found drift gravel and small
bowlders, the locations of which are seemingly inexplicable, by the glacial
theory.
Near Newark, and north of the high grounds which divide the waters
of the Licking river from those of the Moxahala and its tributaries, are
other and larger deposits of gold-bearing sands. The place examined by
me was one and a half miles south-east of Newark. Here is a range of
drift terraces, about 50 feet above the bed of the Licking river. These
terraces are cut through by small streams from the hills, to the south,.
and in the narrow ravines the gold is obtained, from the sands and clays.
The terraces contain also bowlders of granitoid rocks, quartzite, and
small pebbles, of white quartz. Bowlders of limestone, containing fossils
of the Niagara and Clinton groups, were also found in the terraces. The
quantity of gold is small, but, in my own experiments, nearly every panful of dirt showed the " color." Mr. Jacob Schock, jeweler, of Newark,
reports finding gold in small fragments of quartz.
EXPLANATION OF THE MAP OF SECTIONS.
The map is intended to show the stratigraphical position and range of
the lower strata of the coal measures, extending from the north line of
the 2d District to the neighborhood of Nelsonville, on the Hocking river.
The distance isabont 40 miles.
The map is divided by horizontal lines into spaces, which represents
10 feet, in vertical distance. The rocks in the hills are presented very
much as a hay-stack would be, if cut through vertically by a hay-knife.
As the rocks dip to the east and south-east, by going in those directions
one is able to obtain the higher strata, and by'measuring all the rocks,
we are enabled to place them in order, in the vertical series. By bringing the many sections thus obtained, together in a systematic grouping,
we obtain the map herewith presented.
It is believed that this new plan of grouping sections, thus presenting
at a glance the features of our geology, will be approved. The observer
can see, from such maps, what strata are persistent and wide-spread, and
what are merely local. He can go back in thought to the time of the
deposition of the layers, and see where the stronger currents swept, carrying and distributing coarse sands and gravels, which now form sand
rocks, and also where comparatively quiet waters deposited the finer sediments, which now constitute our clays and shales. He,can almost see
the ancient vegetation of the coal-measures, now growing in small insular
patches, and now covering with its luxuriant growth vast savannahs,
