The height of the summit at the cross-roads, 2 miles west of Newburg,
is 375 feet (by barometer), above the Duck creek bridge at Newburg.
On the farm of Mr. Leonard McKee, in Olive township, Noble county, the
coal (the same seam as David McKee's), is 5 feet thick below, with 1 to 1~
feet parting of clay and 8 inches of coal above. There are two seams of
limestone above the coal, one 43 feet and the other about 60 feet above.
The summit of the hill above Leonard McKee's house is 380 feet (by barometer), above the floor of Blake's bridge, over Duck creek, Olive township. The seam of coal is 310 feet above the level of the bridge. On the
hills west of Blake's bridge, the same seam of coal is found, but generally
thinner. On the land of Aranda Woodford it is reported 3 feet thick.
Here the coal is, by barometer, 295 feet above Blake's bridge. As we go
north from Olive township, in ascending the Duck creek valley, the coal
gets higher and higher in the hills, and at last disappears.
On the farm of Fulton Caldwell, Esq., in Olive townsnip, about a mile
below his house, we find 50 feet of sandy shales making cliffs on the immediate bank of Duck creek. Underneath these shales comes up, as we
go north, (for the dip is strongly to the south), a limestone 1 foot thick,
rich is fossils, below which are 7 feet of blackish shales, also rich is fos
sils, and under the dark shales is a foot of coal with vertical planes N. 720
W. At "Soak'em" we obtain a section of strata 50 or 60 feet below the
coal, composed of clay shales of different colors and one stratum of limestone in nodules. This lower coal under the fossiliferous limestone is, by
barometer, 303 feet below the "sandstone coal." The examination did
not extend beyond the village of "Soak'em."
SALT IN THE DUCK CREEK VALLEY.
The wells bored for oil in the valley have generally revealed brine. A
deep well near Soak'em, Olive township, Noble county, bored by the Ohio
Valley Oil Company, struck a light colored sandrock at 763 feet, and continued in it to the depth of 875 feet, when the boring stopped. This well
has yielded a copious stream of strong brine which comes up from the
bottom sandrock. If, as I have much reason to expect, the " sandstone
coal." of the Duck creek valley, is the geological equivalent of the Pomeroy seam, then the light colored sandrock which affords the brine at
Soak'em is the equivalent of the saliferous rock reached by the salt wells
at Pomeroy and on the Hocking river. The saliferous rock probably belongs to the upper Waverly. The New Jersey Company's deep well on
the Dearth farm, Jefferson township, Noble county, passes through the
same sandrock as the Soak'em well and found in it abundant brine.
While therefore we may infer that the great salt-bearing sandrock which
underlies the coal measures in south-eastern Ohio is entirely accessible
in the Duck creek valley, it is a matter of good fortune to this district
