Waverly, 



In this section the eighteen feet of sandstone represents the Conglom- 

 erate, and the top, white layer, filled with stigmariae, is the horizon and 

 *' bottom rock " of Coal No. 1, which is here wanting. At Motes's bank, as 

 ilPustrated in the first section, the fire-clay of this coal rests directly 

 upon the Waverly, 



On Thomas Owens's land, in Knox township, the out-crops of five 

 coals are exposed below the gray limestone, and between the lower coal 

 and the Waverly are twenty-seven feet of blue shale, containing thin 

 bands of shaly sandstone, but no trace of any rock resembling the Con- 

 glomerate. 



Referring again to the section at Lozier's quarry, if Prof. Lesley's sug- 

 gestion in regard to the Mahoning Valley, that we should look for the 

 continuance above Coal No. 1 of the massive beds of Conglomerate exposed
