It appears that the shell marlbeds in which are intermingled the organic remains from thesecondary, are confined to a narrow belt which may be tracedalong the eastern border of the formation. Section No. 5 is designed to show the relations of the shellmarl to the white Eocene beds of the Neuse, which do not ex-tend south-westward to the Cape Fear.

The section shows the marl beds of Mr. Wadsworth, ofCraven count3^ It will be observed that the shell marl is in contact withthe drab colored marl, the entire mass of the lignite forma-tion of the Cape Eear being absent. At this place, thebrown earth is present tilHug the ancient fissures of denuda-tion. The shell marl is not present at this point, but appearsin the same relative position three or four hundred yard*;west from this bed. § 58. The foregoing sections show the diverse nature of thebeds composing many of the bluffs of the Cape Fear, Neuseand Tar rivers. The same facts would be also shown by sec-tions at many points upon the Roanoke and Meherrin rivei-sfarther north. TJie position of the shell marl seems to change,as i
