Typically marine fossils were found in the Ames, Pine 

 Creek, Brush Creek and Kanawha Black Flint horizons. Fos- 

 sils were found in the Pine Creek Limestone only in Upshur 

 County, just across the county line from Lewis, and these 

 were of a broken and fragmental nature, as if the shells had 

 been transported to this point from some more remote home 

 by currents, having been worn by the sand which makes up a 

 large portion of the matrix in which they are now enclosed. 



Non-marine fossils were found in Numbers 3 and 11 of 

 the above table. Number 3 has been named the Orlando 

 Limestone by Reger in a preceding Chapter. Number 11, a 

 band of limestone nodules, 35 feet above the Bakerstown 

 Coal, was discovered by the writer in the cut of the Mononga- 

 hela Valley Railroad at Jackson Mill, but as it is not known 

 elsewhere and has not been traced through the area, no name 

 is given to it. 



The following section, measured at Jackson Mill, begin- 

 ning at the supposed horizon of the Bakerstown Coal, which 

 is here concealed by the fill of the electric railroad, but is ex- 

 posed along the valley of West Fork River both north and 

 south of the section at a distance of half a mile in either di- 

 rection, was obtained by the writer with the aid of a hand- 

 level and is given in ascending order :
