850 GEOLOGY OF OHIO. 
being three feet six inches thick, and of good quality. In the bed of 
the stream was seen the Putnam Hill limestone, with four inches of 
flint above it and eight to ten inches of siderite ore upon the flint. In 
the bed of Buckeye Creek, a little below Saltillo, we find a body of lam- 
inated micaceous sandstone, in which lie buried petrified logs of con- 
iferous wood. This is the finest locality for specimens of such wood I 
have met with in the State. The top of the laminated sandstone is only 
a few feet below the Putnam Hill limestone, the interval being chiefly 
made up of bluish clay shale, of which six feet were seen. In the sand- 
stone are many indistinct impressions of plants, all showing that they 
were drifted. © 
In all this region, the Nelsonville seam of coal is to be found, as shown 
in the Report for 1869. 
Coal Seams above the Nelsonville Seam.—In the Report for 1869, two seams 
of coal were seen on the upper waters of Sunday Creek; the lower called 
the Norris, or Middle seam, and the upper the Stallsmith seam. I am 
now inclined to believe that there is, in the Hocking Valley, a third, the 
place of which is between the horizon of the Norris seam and the Nel- 
sonville seam. At various places we find a coal from eighteen to thirty 
feet above the latter, and generally separated from the latter by clay 
shales weathering yellow. 
On the land of Thomas M. Boyles, near the mouth of Meeker Run, 
York township, Athens county, there is a seam of coal about twenty- 
seven feet above the Nelsonville seam, the interval, so far as seen, com- 
posed of clay shales. It is three feet thick. Over it is a black bitu- 
minous shale, containing marine shells (Lingula), with a clay shale above, 
containing coal plants. A sample of this coal was analyzed by Professor 
Wormley, with the following result : | |

On the Cawthorn farm, on the Bessemer Company’s lands, is a seam of 
coal, about three feet thick, twenty-five feet above the Nelsonville seam. 
Here the interval is formed of yellow clay shale. On the upper Snow 
Fork the same kind of yellow shales are seen near the road, with an un-
