The Eocene§ is found in North Carolina, between the Neuse and the 

 Cape Fear, and in limited outcrops throughout the triangular region be- 

 tween Newbern, Goldsboro and Wilmington. It consists of a light 

 colored, consolidated marlite, as in the steep bluffs on the Neuse, 10 

 miles below Goldsboro, or of a shell conglomerate as seen about New- 

 bern, and 8 or 10 miles up Trent river, or of a white calcareous sand- 

 stone, more or less compacted, as on the Neuse near Goldsboro; or of 

 a gray and hard limestone, as about Richlauds in Onslow; or of a 

 coarse conglomerate of worn shells, sharks' teeth, and fragments of 

 bones and stony pebbles, as in the upper part of Wilmington and at 

 Rockj' Point; or of a fine shaly infusorial clay, light gray to ash coL 

 ored, as in Sampson county near Faison's depot. The outliers show 

 that the formation, though limited in thickness, had a great horizontal 

 extent, and once extended quite into the hill country of the State, and
