The Upper Goal Measures 



South from the railroad line bounding our observations, the 

 greater portion of the section, which we have been discuss- 

 ing, disappears and the only information to be obtained 

 respecting it is found along the line of outcrop on the west, 

 or on the steep mountain slopes on the east. In no other 

 portion of the basin can details be obtained respecting the 

 strata below the Waynesburg coal. To give a fair illustra- 

 tion I have introduced for comparison four sections from the 

 east side of the basin and four from the west side as follows : 



I from Wheeling. 



II from Barnesville, Ohio. 



III from near Georgetown, Ohio. 



IV from near Yorlc, Ohio. 



V from Ligouier, Penn. (Rogers). 



VI from Monongalia Co., West Virginia. 



VII from Uniontowu, Penn. (Rogers). 



VIII from Elk Lick, Penn. (Rogers).
