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, who 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 m 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 Backingham, 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, this sand- rock and the 

 one abore 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,
