ON A PORTION OF A KAISED BEACH, ETC. l66 



VIII. — On a Portion of a Raised-Beach on the Fulwell Hills, near 

 Sunderland. By D. "Woolacott, B.Sc. (Durham), Honours 

 Medallist in Geology and Physiography, South Kensington. 



A EAiSED-beach, which probably occurs at two distinct levels, 

 and two sea-worn caves have been recorded as occuring at the 

 "Whitburn Lizards on the eastern part of Cleadon Hills, and 

 since they are closely connected with the subject of this paper 

 it will be well to briefly notice them. 



According to Professor Lebour the exposure of the raised- 

 beach, which occurs at a lower level, is a typical example of 

 one, being traceable along the eastern side of Cleadon Hills from 

 "Whitburn to Marsden, and almost completely round them, (i) 

 The village of Cleadon, which lies rather over one hundred feet 

 above sea-level, is built upon it, as the Greological Drift Maps of 

 Sunderland and district clearly shows. It has lately been well 

 exposed in a gravel pit made to the west of Cleadon Hall, near 

 the road between Cleadon Lane station and Cleadon village. At 

 the present time a deposit of gravel about ten feet thick occurs, 

 resting on a bed of yellow sand, which is distinctly false bedded, 

 and of which about seven feet is exposed. Professor Lebour 

 informed me some time ago that rolled flints of a large size had 

 been found in this gravel, several of which I have since collected 

 out of the same bed. 



The other exposure, which occurs at a slightly higher level 

 on the same hills, has only been noticed on the north-eastern 

 side of them, good sections of it, which Mr. E. Howse studied, 

 being exposed some years ago in a Railway cutting at "Whitburn 

 Lizards. The Railway runs along the hundred feet contour line 

 at this place. (2) 



On the eastern side of these hills a sea-worn cave was dis- 

 covered in 1878, whilst another was found close to it a year 

 later. They both lie at a height of one hundred and forty feet 

 above sea-level. ('"^
