The Ohio Naturalist. 
[Vol.X, No. 5, 
No. 6 is dark gray in color, is not so compact as 4 and 5 below 
it, and has more jointing planes than these layers. It rests 
immediately upon No. 5 from which it is separated by an uneven 
bedding plane and has a thickness of 16 inches. 
Nos. 5 and 4 having a thickness of 7 inches and 23 inches 
respectively, are brown-gray in color, quite compact, weather 
less easily than the upper layers, and are said to be the best 
stone in the quarry. These layers are separated by a peculiar 
wavy bedding plane the elevations of which measure 1 to If 
inches and 3 to 5 inches between as seen on the rock face. 
No. 3 measures 20 inches, is of a gray color slightly darker 
than the layer below it and also purer lime than that layer but 
not so good as those next above it. It is more compact than the 
lower layer. 
No. 2 is a thin calcareous shale parting of negligible thickness 
and of the color of the stone. 
No. 1 has a thickness of 11 inches, is gray in color and is said 
to weather to a shale condition after a few months exposure. It 
is not as tough as the middle layers and rests upon the coal. 
In the south wall of the quarry the limestone presents five 
layers below the conspicuous shale parting but of nearer equal 
thickness than shown in the above section. 
The outcrop of the Vanport noted above occurs in the hill-top 
just above the township road in a private roadway about 30 
yards north of Mr. Adam Cocklin’s barn and about 200 yards 
north of the quarry. This stratum is poorly exposed and as 
nearly as could be determined it is 6 feet, 5 inches thick, caps 
the hill and is thinly covered with drift. It may be seen again 
in the township road \ mile east of this outcrop and near the 
residence of Mr. Adam Wise, where it again caps the hill. Mr. 
Wise reports the presence of a thin coal beneath it. 
Little more can be said of this limestone from the poor out- 
crops afforded. It is bluish gray in color and less fossiliferous 
than its companion so far as could be seen. 
It probably occurs in all the surrounding hills whose strata 
are high enough to carry it but with its outcrop obscured by drift. 
Its occurrence here in rather heavy body and above the 
Putnam Hill, which at this point exhibits the greatest develop- 
ment it is known to possess, is somewhat in contrast with the 
supposition that the two limestones do not overlap and that as 
the one appears the other disappears. 
One mile south of the Middle Branch on the farm of William 
Worstler a quarry was operated on a small scale for many years 
and the stone burned for lime with the underlying coal. The 
following section indicates the character of the stratum in this 
quarry.
