Immediately to the north of Crimden beck is a mass of 

 boulder clay protected from the sea by a heavy bank of sand. 

 The surface of this boulder clay bank, which skirts the north 

 side of Hesleden or Crimden Dene, is covered with a layer of 

 sand, which, if removed, would doubtless reveal an extensive 

 chipping site, as flakes are in evidence wherever the sand 

 is removed along the edges of the bank by rain or wind. 

 On a patch of ground denuded of sand I picked up several 

 large flakes of pink and yellow flint and a fine scraper. The 

 scraper is a triangular specimen of dark brown flint with a 

 neatly worked edge, and part of the crust of the flint nodule 

 from which it was formed remaining (Plate VI., fig. 2). 



Flints may be traced sparingly for about two miles to the 

 north as far as the Black Hall Rocks, in which place they are 

 very abundant on the fields above the caves and a little to the 

 north. The site seems to have been a favourable one for the 

 flint chippers, water being supplied by a small stream running 

 nearly parallel to the coast for some distance, and the ground 

 being well sheltered and fertile. The implements are picked 

 up on the ploughed fields, and are consequently more or less 

 damaged. I have recorded from here : 



Scrapers, 7 ; borer, 1 ; very small or pigmy implement, 1 

 cores, 12 : flakes and chips about 600; bruised quartzite 

 pebbles about 12. 



Between Black Hall Rocks and the site at Horden presently 

 to be described are several large ravines cut out of the boulder 

 clay and the underlying magnesian limestone. Flakes and 

 cores are plentiful along the edges of these ravines ; in one 

 spot where long slender flakes occur I have found two or three 

 pigmy implements. On the top of a large bank of clay 

 immediately to the north of the mouth of Castle Eden 

 Dene the flakes found were remarkably large, sharp and 

 unweathered.

 I first detected the existence of a well-defined coast chipping- 

 site on the sea banks near Horden, about a mile to the north
