Soft, chalky limestone, indurated in places, con-taining Turritella carinata. Nucula ovula. Corbnla gibbosa. Pteropsis lapidosa 12 Along the road to Thos. B. Cox.s house deep red, compact sands, and decomposed glauconite with pebbles near base, are seen overlying the material composing the preceding sections. Darge masses of silicified coquina and chalcedony (buhr-rock) with numerous poorly preserved fossils, Mortonia, Turritella obruta, Corbula alabamiensis, etc., Claiborne fossils, occur from eight feet of the base to the hill summit. The observed thickness along this road was 52 feet. Section on Thos. B. Cox's land, six miles southeast of McBean station, from his residence to creek, one-half mile to the northeast. Barnwell sand.

The bluff has been referred to in geologic literature more often than any other Georgia locality. Probably the first reference was made by William Bartram, ' the...
