4. Discussion of and Conclusions from the Tables. 



According to Tuomey, at White Point Creek in northeastern 

 Horry, very near the ocean shore line, there is a deposit of shells 

 among which are Venus mercenaria, Ostrea Virginica, Scapharca 

 incongrua, Area Noae and a species of Pectunculus. This deposit 

 is doubtless Pleistocene, as he claimed. Again Tuomey gives a short 

 list of fossils from Laurel Hill bluff, northeastern Georgetown 

 County, which includes Area ponderosa, Scapharca campechiensis, 

 Mulinia lateralis, Spisula similis, Donax variabilis, Rangia cuneata, 

 and Oliva litter ata. It is interesting to note that the fossil bed here is 

 eight feet above tide, the highest elevation yet known for the Pleisto- 

 cene fossil deposits of the State. At other places in Georgetown 

 County southward from Laurel Hill, especially along Winyah Canal, 

 characteristic Pleistocene fossils have been found. These localities 

 in the northern part of the Coastal belt of the State, combined with 

 two or three others mentioned by Tuomey as occurring in northern 

 Charleston County, together with the localities listed in these tables, 

 show plainly that along the entire shore of the State the deposits of 

 Pleistocene fossils surely extend from White Point Creek in the 

 north to Beaufort, and probably beyond toward the south, in one 

 continuous sheet, except where cut through by streams. 



As to the ages in which these species occur, it is seen that at least 

 95 per cent of them, as known certainly, live along the coast today. 

 It is possible that the percentage will run higher when more thorough
