north. The Ames was visited at Carpenter, Meigs County, and 
at the shale quarry of The Athens Paving Brick Co., in the 
town of Athens.

Shale. 30 
Ames Limestone . 1 10 
Shales, blue and red. 35 
Patriot Limestone . 0 10 
Shale, black, fossiliferous. 
In the above section the Ames limestone is a single layer with 
numerous vertical divisions which cause the stone to come from 
the cliff in angular blocks. This is quite different from the 
Ames at Carpenter where it is shaly. The Patriot is a yellowish, 
nodular rock, cherty in places but highly fossiliferous. Large 
specimens of Productus semireticulatus and Spirifer cameratus 
are common. The underlying black shale is thickly spotted 
with Chonetes verneuilanus in all stages of growth from very 
small to large robust indviduals.
