In the northern part of Section 15, Madison Township, near the 

 head of Higgins Run, specimens of the fresh or brackish water pelecy- 

 pod, Naiadites ohioense n.sp., were found in the dark shales which 

 lie directly above the Sharon coal; they are not abundant, however, 

 and constitute the only fossil discovered at this locality. The samples 

 of shale which were examined were taken from the roof of the mine on 

 the farm of John Alexander, where the geologic section below was 

 measured: 



Potts ville formation Ft. In. 



Shale, gray 10 



Shale, dark, sparingly fossiliferous 2 



Coal, Sharon 2 2 



Sandstone, Sharon conglomerate equivalent 30 



Waverly formation 



Sandstone and shales 40 



In the western part of Section 15, Madison Township, Naiadites 

 elongata Dawson was obtained from the Henry Odle mine in the creek 

 bed, where the dark shales afford good material for collecting. This 

 fossiliferous shale is also present at the other mines in the vicinity. 

 In Section 11, the Sharon ore is present above the shales, but it was 

 not examined for fossils. The ore is 10 inches thick and lies nearly 

 10 feet above the Sharon coal. This bed was formerly mined in 

 Section 22, Madison Township, for use in the charcoal furnaces. 



Jackson County. At the old, abandoned Glen Nell mine in 

 Section 21, Washington Township, about 4 miles northwest of Well-
