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 lght 
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 Richlands 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 
Rocky 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
