lime for the farmer. Fragments of a higher limestone, XII, wcro seen 

 50 feet above XI near the West Virginia line, but its place was not 

 reached elsewhere in Washington county. 



The Nineveh limestone, 145 to 153 feet above the Upper Washington 

 near the West Virginia line, is reached at many places in these townships. 

 The interval increases eastwardly to 180 feet on the border of East and 

 West Finley, but farther east it decreases to 160. The rock is coarse, 

 dark, and weathers blue and rough, though some portions become yellow. 

 A third limestone, rarely exceeding 2 feet 5 inches, is very persistent 

 at 103 to 123 feet above the Upper Washington. It may be equivalent 

 , to a limestone seen in the western part of Greene, but it is not safe to ■ 

 make any correlation of these limestones in this variable interval — at 

 least until more detailed information has been secured. 



The Upper Washington is 15 to 20 feet thick, and the Franklin, 30 

 to 40 feet lower, is a persistent dark limestone 20 to 30 feet above the 

 'Middle Washington. The Blacksville and Lower Washington appear 

 wherever their places are exposed, but the}^ vary greatly in thickness. 

 The coals are wholly unimportant, and nothing to represent the Boyd, 

 JoUytown, Waynesburg A or B was seen. The Waynesburg is the only 

 prominent sandstone. A shale, apparently equivalent to the Cassville, 

 overlies the Waynesburg coal bed at many places, but it carries no lime- 

 stone.* 



Passing over into Greene county, one soon reaches an area retaining 

 the highest members of the Dunkard formation. A high ridge separating 

 Wheeling and Fish creeks at the west from Ten-mile and Dunkard 

 creeks at the east passes from Morris and East Finley of Washington 

 county into Morris, Kichhill, and Center of Greene. From this ridge 

 in Greene long, irregular "hogback" ridges pass off into the townships 

 of Jackson, Aleppo, Gilmore, and Springhill and thence into West Vir- 

 ginia, most of them capped by the Gilmore sandstone, and occasionally 

 one shows some higher rocks. The section shows great variation in 

 western Greene. 



A principal fork of Wheeling creek heads up against this ridge in 

 Aleppo township and flows northwest into Eichhill. The succession along- 

 this stream as ascertained by Doctor White, somewhat condensed from 

 the original notes, is :
