THE BIRMINGHAM SHALE. 



The Birmingham Shale of Stevenson 13 , consisting of red, 

 sandy and variegated shales, and apparently lying between the 

 Elk Lick Limestone and the Upper Ames Limestone, is pres- 

 ent in Lewis and Gilmer but not conspicuous, a portion of 

 its horizon being occupied by the Grafton Sandstone. Plate 

 XIX shows its typical appearance. 



THE GRAFTON SANDSTONE. 



The Grafton Sandstone of White 14 , named from its occur- 

 rence at Grafton, West Virginia, is frequently present in 

 Lewis, where it crops but is not always prominent. Tt is 

 usually massive and gray or brown in color, but frequently 

 becomes shaly. In the neighborhood of Vandalia, Skin Creek 

 District, it carries quartz pebbles.

The stone is gray, weathering to brown, medium coarse, 

 medium hard and micaceous, with numerous joint and bed-
