I02 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 H 

 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 ]~:irting 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 abotit 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 'J 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.
