Joining these points, if this seam exists at Carrollton, and is regular, 

 it should be at an elevation not far from 460'. Judging from the 

 indications on the west, north, east and south sides of the county, if 

 No. 6 extends through to Yellow Creek, it is nearly level, inclining 

 slightly to the east of south, in consonance with the results in adja- 

 cent counties. If it rises between the valley of Connoten and that 

 of Yellow Creek, either in the form of a ridge or a crown, the proofs 

 are yet to be made public. 



On the west it is nearly level, inclining slightly to the south. At 

 Salineville, on the east, the Big Seam rises to the west at the rapid 

 rate of 80' to the mile, in places 100', which would soon carry it 

 above the highest hills. In the present state of information, the 

 Salineville bed No. 6 cannot be connected with either the No. 6 of 

 Sandy valley or of Tuscarawas valley. A thorough exploration 

 would probably disclose a disappearance by thinning out, and the 

 appearance of the Salineville group at a higher geological level. 



I have already shown that the Salineville No. 6 does not connect 

 with that of Irondale. New Lisbon, in the valley of Little Beaver, 

 is fifteen miles north of Irondale, where No. 6 is 515' A. (N.). If this 

 is the same bed as at Hanover, 560' A., it is nearly on the line of 

 bearing, and its elevation at New Lisbon is what it should be. 



If I am right, such a misconception of the geological structure of 

 an important coal field is fundamental, and neither the number or 

 extent of the seams are to be. relied upon. The coal beds are as 

 regular and persistent as any of the strata, but cannot be assumed to 

 be more so. 



The teachings of the accompanying table are very significant, show- 

 ing that in ten (10) sections extending from the western part of Penn- 

 sylvania around to the valley of the Muskingum, where my first radial 

 is situated, there are, as to the beds of coal and limestone, none that 

 are continuous. If there were space to compare the strata of shale, 

 sandstone and iron ore of the same section, this difference would be 

 equally evident. In this universal want of identity among the beds 

 we are required to consider No. 6 as an exception. 



At the mouth of Yellow Creek there are visible in the same profile 

 seven beds of coal above low water mark. The lowest one, not num- 

 bered in the Report, is thin, and is probably local. Next above it is 

 the " Creek vein," entitled No. 3 in the general profiles. The "Groff 

 seam," No. 6 of the local profile, or No. 7 of the general section, has 

 above it another seam, which should be No. 8, and is two seams
