SUPPLEMENTAL REPORT-—-HOCKING VALLEY. 851 
opened seam of coal above. Here the distance down to the Nelsonville 
seam is twenty feet eight inches. 
A few miles north-east of the Baird furnace, on the land of Jacob 
Martzoff, there is a seam of coal which I took to be the Nelsonville seam. 
Under the coal is Coal No. 5. About twenty-five feet above, is another 
seam, not opened; and twenty-seven feet higher, another. The latter I 
supposed to be the middle, or Norris seam. If the determinations are 
right, it is evident that there is a seam between the Norris seam (the 
probable equivalent, in this region, of Coal No. 6a) and the Nelsonville 
seam. Here ten feet of yellow clay shale were seen over the Nelsonville 
seam. 
In the hills north of McCuneville, a seam of coal three feet thick is 
seen, twenty feet above the Nelsonville seam, with similar yellow clay 
shale between. More full investigations will, I think, reveal a well- 
defined horizon of a coal seam about midway between the Nelsonville 
(No. 6) and the Norris seam (No. 6a). The seam is not continuous by 
any means, nor is the one next above; and when one is found without 
the other, it is easy to confound them. 
The Norris Coal is named from a bank near Millertown, on Upper Sun- 
day Creek, in Perry county. At this bank the coal is six feet thick, 
with two partings, one one inch and the other three inches in thickness. 
The coal is of fair quality, and well adapted to all ordinary use. The 
seam was here determined by Mr. Gilbert to be ferty-six feet above the 
Nelsonville seam. It is to be traced in most of the hills in this region, 
but sometimes it fails altogether. On the West Fork, above Bucking- 
ham, on the land of Benjamin Sanders, Monroe township, we see the out- 
crop of the same seam. The interval down to the Nelsonville seam— 
here well seen—as measured by Mr. Ballentine, is forty-seven feet. The 
coal en Mr. Sanders’s land is thin and irregular. On the opposite side of 
the valley it measures only two feet in thickness. On the Grigsby farm, 
Section 9, Monroe township, the seam is four feet thick, and has been 
mined for neighborhood use. Two samples of this coal were analyzed by 
Prefessor Wormley, with the following results:
