cle is flanked on both sides by drift : that on the east, or 

 Sherringham side (left of the diagram), consists of alternate 

 layers of loam, clay, and white chalk rubble several feet thick, 

 which must have been deposited horizontally although now 

 vertical. These are traceable from within a few yards of the 

 pan to near the summit of the chalk, for a height of 60 feet 

 or more. Between the two prongs of the fork, near the top 

 of the cliff, are curved beds of drift. On the western or right 

 side of the pinnacle the beds of drift are not the same as those 

 on the left. They consist first, and nearest to the chalk, of 

 strata of flinty gravel ; secondly, layers of sand with round 

 flint pebbles; thirdly, loose yellow sand, alternating with 

 loam. These join on to curved beds of drift, which are re- 

 presented near the top of the cliff on the right of the diagram — 

 innumerable layers of sand and shingle, some of them bent 

 round upon themselves and containing seams of carbonaceous 

 matter, or in other places small white pieces of broken shells. 

 Near the bottom of the section argillaceous till rests im- 

 mediately on the crag, and on one side comes in contact with 

 the chalk pinnacle near its base. Through this till small 

 pieces of chalk and flint are interspersed. Another included 

 fragment of chalk (c) occurs nearly half-way up the cliffj en- 

 veloped in drift to the westward of the pinnacle. 



* This sketch is taken principally from my own drawing, but corrected 

 from a view by Mr. Simons taken in March 1840, when the waves during 

 a storm had reached about 8 feet above the level of the pan or crag, re- 

 moving the talus which previously masked the junction.
