On the land of Samuel Thomson, near Maxville, Monday creek township, Perry county, we find a compact iron ore in thin layers, the whole
measuring sixteen inches. It rests on an earthy blue limestone six inches
thick, which is separated from another seam of blue limestone, eight
inches thick, by five inches of blue clay. Under the limestone are fourteen inches of black sandy bituminous shale, below which are twentytwo inches of coal, this with its under clay resting upon a sandrock. A
section of this ore and associated strata is the Sec. No. 11 in the map of
grouped sections. No samples of this ore were brought away, but from.
the unusual thickness of the stratum it is worthy of investigation.
A seam of ore six inches thick was seen near Cusac's mill, on Jonathan's creek, Newton township, Muskingum county. Sec. 30, on the map
of grouped sections, represents the position of this ore.
On thq land of John Lyle, Sec. 14, Newton township, a layer of nodules of iron ore three inches thick was found, resting upon a stratum of
calcareous ferriferous flint, which, in turn, rests upon, or rather, is
cemented to a seam, fifteen inches thick, of blue limestone, under which
are three inches of coal. The surface of the flint stratum is covered
with impressions of the marine plant Spirophyton cauda-galli, or allied
species. Fifteen feet above is a thin layer of sandstone, with the same
vegetable impressions upon it. A section of this group of strata' is on
the map of grouped sections No. 33.
Between this horizon of ore and the Putnam Hill limestone above, no
other range of ore was observed.
Above the Putnam Hill limestone we find the first ore from five to
eight feet over the limestone. It is seen on the map of sections as Sec.
36. Here the nodules of ore are often quite large, and the location is
worthy of investigation. I have no doubt the ore is of good quality. In
sebtion 40, on the same map, is seen a layer of nodules of ore four inches
thick, belonging to the same geological horizon. It is eight feet four
inches above the Putnam Hill limestone, resting upon blue calcareous
shales which are highly fossiliferous.
At Flint Ridge, a layer of ore is reported resting upon the top of the
Putnam Hill limestone, which here includes the calcareous shales seen at.
the last locality. The shales and limestone have the same fossils.
Higher in the series, ore in considerable quantity was found on the
land of Henry Welch, Salt Lick township, Perry county. No measured
section was made, but its place, by estimate, is about 30 feet below the
great Nelsonville seam of coal. It lies in layers of nodules in blue clay
shale. One of the nodules was taken for analysis. Prof. Wormley reports, in No. 6 of the table, the metallic iron to be 27.04. The details of
the analysis are not given. Should this ore be found well situated for
easy stripping, it would doubtless serve as a good purpose for mixture
with other richer ores.
