SUPPLEMENTAL REPORT—HOCKING VALLEY. 853 
under a heavy sand-rock, and that this sand-rock may be traced to Mox- 
ahala, where the Fowler coal is found under it. In this confusion, Mr. 
J.G. Chamberlain, the intelligent manager of the Moxahala furnace, re- 
quested me to visit the ground. and aid in solving the problem. Fortu- 
nately, Mr. Chamberlain, whe is a civil engineer, had instrumentally 
taken the interval from the Fowler coal to the regular upper limestone, 
which he had opened in many places in quarrying it for the furnace. 
Starting with the Fowler coal with the sand-rock above it, the section 
was carried as far as possible to the east, or a little south of east, into the 
ridge on which Oakfield is situated. The limestone and our levels helped 
us across the ridge. In a branch of Sunday Creek, a little east of Oak- 
field, we found the top of what we both believed to be the same heavy 
sand-rock found over the Fowler coal. It was brought by the dip down 
to about the level of the Fowler bank, as shown by the barometer. This 
dip ‘would be about equal to the thickness of the sand-rock, or about 
thirty-five or forty feet. A very little above the top of the sand-rock, on 
the Sunday Creek side, we found, on the Donnelly farm, a seam of coal 
something more than four feet thick. This coal has all the appearances 
of the Stallsmith seam, in the vicinity of Buckingham, showing the 
same resinous and cementing character. Believing this to be the Stall- 
smith seam (the equivalent of Coal No. 7), I went into the ravine below 
the sand-rock, and searched for the Norris seam, which should be below 
that rock or some forty feet below the Stallsmith seam. I found a 
bituminous band, with only an inch of coal. This coal was carefully fol- 
lowed down the narrow valley. Under this coal, which is in places per- 
haps a foot thick, we found a sandy shale, which, lower down the stream, 
passes into sand-rock. Seen at a little distance, tnis sand-rock and the 
one above it appear to be merged into one. We traced the thin coal and 
the lower sand-rock down the stream, until, underneath the latter, the 
Great or Nelsonville seam comes to the surface. We had thus found in 
this branch three seams of coal—the Stallsmith (or Coal No. 7). the Norris — 
(or Coal No. 6a), and the Nelsonville (or Coal No.6.) The middle one of 
these is the Fowler seam of Moxahala, which is under a sand-rock, it is 
true, but not the same rock which covers the Nelsonville seam on the 
middle fork of Sunday Creek. I subsequently added strength to this 
conclusion by explorations in the valleys of some of the branches of the 
Moxahala. In a letter received subsequently from Mr. Chamberlain, he 
writes as follows: ‘“ The main question is settled. I am now fully will- 
ing to concede that the Fowler coal is the Norris, or the first above the 
great vein, and that the Donnelly coal is the Stallsmith.” 
West of Moxahala, the Fowler seam may be traced for several miles,
