A careful examination of the fossils contained in the cabi- 

 net of the University of Mississippi failed to bring to light 

 any fossils of this stratum (Ferruginous Sands). Through the 

 courtesy of Dr. Geo. Little I was shown the section made by 

 him along the course of the Chickasawhay River and I found 

 nothing that in the least resembled this stratum. There are 

 however several specimens of leaf impressions in a red shale 

 labeled " Claiborne," for the age of which Dr. Hilgard must 

 have relied upon stratigraphical data. The only representative 

 of the strata showing at Claiborne Bluff is the " Ostrea sellse- 

 formis bed " (No. 6* of Aldrich) which occurs at Enterprise, 

 eight miles southwest of Enterprise on Suanlovey Creek, and 

 eight miles southwest of Decatur, Newton County. 



In the railroad cut northeast of Enterprise occurs a light 

 gray claystone having fucoidal impressions, just like the buhr- 

 stone at Lisbon, Ala. There is another exposure of the Lisbon 

 strata in a railroad cut twenty- five miles west of Meridian, as 

 follows : 



Surface soil 2 feet. 



1 . Light gray sandy clays, — fossiliferous 12 feet. 



2. Gray buhrstone with root-like impressions on upper 



surface 6 feet. 



At Lisbon, Ala., a more careful examination has shown the 

 "Scutella bed" (Smith) =/ of O. Meyer's section,! exposed 

 140 feet above the river level, which confirms the connection 

 between Lisbon and Claiborne.^ 



These observations, it is hoped, will assist in establishing 

 conclusively the relations of the Vicksburg, Jackson, and Clai- 

 borne beds. 



Half a mile above the Upper Landing at Claiborne, Ala- 

 bama, a rather interesting section is exposed in the road lead- 

 ing to the ferry. The section given is not one of the whole 

 bluff, but of a small promontory on the roadside, showing 

 however the relative positions of the underlying and overlying 

 strata.
