thicken rapidly and rise to tide-water level and above nearly as far 
east as Wilmington. The Eocene formation thins somewhat, and in the 
southern counties lies almost entirely above tide level, on an irregular 
floor of marine Cretaceous sands and marls. 
The Chesapeake beds thin rapidly southward, and lie mostly above 
tide level in shallow basins on the Eocene or marine Cretaceous. 
The Potomac, the most important of the water-bearing formations of 
the Coastal Plain region, is best developed along the western border of 
this region in the counties southwest of the Neuse Kiver — Harnett, 
Moore, and Richmond. In these counties it is exposed at intervals 
over considerable area; and, dipping gentty southeastward on the 
eroded surface of the crystalline rocks, these Potomac strata doubtless 
carry considerable quantities of water. The Potomac formation also 
reaches the surface over limited areas, both to the north and south of 
the Roanoke River, above Weldon ; and there are also limited outcrops 
of the formation at intervals between the Roanoke and Neuse rivers, 
but in this latter region the exposed areas of the formation are far less 
extensive than between the Neuse and the Pedee, and consequently the 
underground water supplies below the Tertiary marls of the counties 
between the Keuse and Roanoke will probably prove to be less abun- 
dant than in the more southerly counties.
