MORROW COUNTY. 261 
No. 3 is somewhat thinner here than in the section at Iberia and in 
those in Crawford county. , 
No. 4 is not regular in the alternation of beds, nor in its horizon of 
contact with No. 3. Beds of sandstone sometimes occur below the hori- 
zon of separation here adopted. The most of the material is sandstone. 
The shale glistens as if with mica, and the surface is soapy and shining 
when dry. It is appropriately but not correctly called “soapstone” by 
the quarrymen. 
No. 5 graduates below into a blackish slate, which crumbles and be- 
comes blue, making a blue marl. This member is not well seen here. 
No red shale can be seen, nor any indications of it. 
No. 4 contains various mud-markings and irony concretions, many of 
which have a deceitful resemblance to fossil remains. The irony nodules, 
or concretions, have often a marl ball within a scale of one-fourth inch 
of real iron. Some deposits appear like real hematite iron ore. There 
are also calcareous concretions, or irregular masses of more calcareous 
shale or rock, which are hard and firm, of a blue color, and contain iron 
pyrites. They seem to be of the same nature and origin as the silicious 
limestone of Mandeville’s quarry (N. H.4 section 13, North Bloomfield), 
but less abundant here. 
Calcareous and chalybeated waters issue from springs along the banks, 
and make copious deposits of their carbonates on the face of the bluffs. 
Quarries are owned at Mt. Gilead by Charles Russel, George Wieland, 
and by Smith Thomas. | 
About three and a half miles south-east from Cardington, in Lincoln 
township, occur several quarries on the horizon of the Berea grit, the 
exposures being caused by the upper forks of Alum Creek. They all lie 
within the area of a square mile, and are owned by D. M. Mosher, David 
Steiner, Morgan B. Brooks, and Corwin Conard. The beds are about 
horizontal, or show a gentle dip east. The section at Mosher’s quarry is 
as follows, in descending order :

Mr. Steiner’s quarry shows a singular fault or variation of bedding 
An oblique seam crosses the face of the exposure, and on the freshly 
quarried edges the bedding is very evident. On one side of the seam, 
which may be called the lower side, the beds are nearly all thick, run- 
ning from five to eight inches above, and reaching twelve inches below. 
These thick beds terminate on reaching the seam or joint, their ends
