The Upper Goal Measures 



and is the Sewichly. VIII c crosses the Ohio, is traceable 

 along Wheeling creek for several miles, but soon runs under 

 and does not reappear on the other side. IX and X do not 

 cross the river into West Virginia, the former disappearing 

 two miles west from the Ohio, while the latter is seen as a 

 mere streak in the hills opposite Wheeling. It is possible, 

 however, that careful tracing round by the north may estab- 

 lish some connection between our Goal X and the Vniontown 

 coal of Pennsylvania. Goal XI is persistent throughout, and 

 is the Waynesburg. XII was not seen by me at Wheeling, 

 though it is probably the bed noted by Mr. Briggs, eighty- 

 two feet above the last. At Waynesburg and Uniontown, 

 the interval is from fifty to sixty feet. Erosion has so 

 removed Goal XIII and its adjoining rocks that it is to be seen 

 at no point near the Ohio river, but its equivalent in Penn- 

 sylvania is doubtless the top coal at Waynesburg and Union- 

 town, fifty-live feet above the last. These two beds exist in 

 West Virginia on the east side of the basin, but owing to the 

 poverty of exposures no definite statement can be made 

 respecting them. 



The relations of the coals in the several states may there- 

 fore be represented as follows :
