flint implements. Part of a bone knife handle, probably 

 Roman, also occurred. 



Further to the north, between Horden and the mouth of the 

 Wear, and thence to the mouth of the Tyne, Neolithic remains 

 occur only very sporadically. The coast is not protected by 

 sand dunes and shingle banks, the limestone is softer, and the 

 boulder clay less in evidence. More coast denudation seems 

 to have taken place, and the Neolithic chipping sites are 

 probably washed away. Many small ravines and gorges 

 occur, but are for the most part devoid of chipped flints. 



The following gives a summary of flints found up to the 

 present on Durham coast sites : — 



Seaton Carew : flint fragments found in kitchen-midden 

 with Romano-British remains. 



Mouth of Crimden Dene : scraper, i ; flakes, 8. 



Edges of Crimden Dene, and near the coast : flakes, 30 ; 

 cores, 3. 



Crimden Dene, Black Halls, in ruts on old ploughed fields : 

 scraper, 1 ; flakes, 50. 



Black Halls, near the hotel : scrapers, 7 ; borer, 1 ; pigmy 

 implement, 1; cores, 15; flakes and chips about 1,000; 

 bruised quartzite pebbles about 12. 



Black Halls, Deneholme : scraper, 1 ; flakes many. 



Deneholme, Horden : flakes about 150; cores 8-9. 



Horden : about 600 chipped flints on site of the old settle- 

 ment. 



Horden to Sunderland : scraper, 1 ; flakes sparingly found. 



Near Westoe a well formed flake occurred on the top of a 

 stack of limestone in Frenchman's Bay, entirely cut off from 

 the rest of the coast line. 



The study of these coast finds raises some interesting 

 questions respecting the relative age of the coast settlements 

 with those on the fells in the county of Durham. 



There is a striking dissimilarity between the remains found 

 on such a site as that described from Horden in this paper to
