This is certainly an interesting locality, showing as it does 

 the Vicksburg and Midway beds in such close proximity. The 

 Nanafalia and Yellow bluff horizon, viz. , the lower Ivignitic, is well 

 represented and fossiliferous, while so far as observed the beds 

 probably belonging to or representing an upper lyignitic hori- 

 zon are barren. The lower Claiborne light colored sandstones 

 east of the village are not thick, but carry an ample fauna, 

 with the same species as seen at Hamilton bluff on the Ala- 

 bama and along the Savannah and Western road perhaps ^ 

 mile north of Ozark. 



Vicksburg beds form the surface rock at Cuthbert and three 

 miles to the north. They occupy high hills as far as five 

 miles north of this town. Nine miles to the north of Cuth- 

 bert Midway beds crop out on the northern slope of a hill. 

 The estimated distance between the top of the Midway and 

 the base of the Vicksburg is 200 feet. An exposure of no less 

 than 100 feet of Lignitic and lower Claiborne exposure is seen 

 in a deep valley 33^ miles north of town. Here and far- 

 ther east, at least as far as Macon, no fossiliferous beds be- 

 longing to the Eocene series have been detedled between the 

 Vicksburg and Midway.
