of streams. Cites examples of such deflection in various parts of the
world, and notes particularly the apparent operation of this force on the

streams of North Carolina.

Hotmes, J. A.—Geology of the Sandhill Country of the Carolinas. Geol. Soe.
Amer. Bull.,. yol. 5, 1893, pp. 33-34.

Describes the character, stratigraphic relations, age, etc., of the deposits
of the sandhill region of the Carolinas. Recognizes Cretaceous, Eocene,
Lafayette, and Columbia deposits.

The Cretaceous deposits consist of several hundred feet of arkosic sands
with subordinate clay beds. The upper surface is deeply eroded.

Bocene remnants are said to cap many hills at an eleyation of 500 feet
above tide-level. ‘The submergence during Eocene deposition could hardly
have been less than 600 or 700 feet, and may have been several hundred
feet more, and the Eocene waters for a short time may have covered a
considerable part of the Piedmont Plateau and washed against the slopes
of King’s and Anderson’s and the Sauratown Mountains” (p. 34).

The sands and loams of the Lafayette formation overlie unconformably
both the Cretaceous and Eocene deposits. These, also, have been deeply
eroded. :

A mantle of sands and loams, classed as Columbia, overlies all older
formations.

Limonite is reported from Edgecombe, Pitt, Halifax, and Robeson coun-
ties, but the geological horizon is not stated. On the accompanying
geological map the Tertiary is not separated into formations, as the author

says that he does not have sufficient information to draw the formation
lines.

lachians. Nat. Geog. Mag., vol. 6, 1894, pp. 63-126.
The probable connection of the Cape Hatteras axis and the Cincinnati
uplift with a transverse fold in the Appalachian region, which is ex-
pressed in the deformed contour lines in the Cretaceous peneplain of the
latter region, is discussed (p. 81).

rief résumé of the geology of the Coastal Plain is given in this

report. A section across the State prepared by Prof. J. A. Holmes is

included. Sections of wells in Wayne, Pender, and New Hanover counties,
which penetrate Cretaceous beds, are also given.
