WESTLETON BEDS TO THOSE OF NORFOLK, ETC. 91 



reason, also, the Mundesley and Westleton Beds, identified by Prof. 

 Prestwich on the Cromer coast, are not the same as the Eure- 

 T alley Jicds inland." 



Mr. Woodward further states that under the term " Lower Glacial 

 Drift" he would include not only the Cromer Till and Contorted 

 Drift, but also the " Middle Glacial," as he regards them as inti- 

 mately connected ; " hence the Westleton Beds would be Lower 

 Glacial, the Mundesley Beds would come in the debatable ground 

 called Preglacial, the Bure-V alley Beds are Pliocene." 



In a subsequent paper* Mr. Woodward, in speaking of the Crag 

 and Pebbly Gravel, says " In their notes on the pebbly gravel and 

 its relation to beds above and below, Messrs AVood and Harmer 

 have expressed their opinion that on the coast the Wey bourn Sand 

 ( = Bure-Valley Beds) passes up by interbedding into the Cromer 

 Till, while the pebbly gravels around Norwich that immediately 

 underlie the Lower Glacial brickearth, were considered by them to 

 be, to some extent, the equivalents of the Cromer Till." 



He then observes, " Neither my colleague Mr. lieid nor myself 

 have seen any evidence to corroborate this opinion ; on the contrary, 

 the line between the undoubted pebbly gravels (which are grouped 

 by us as Pre-glacial) and the overlying Glacial Drift is generally 

 sharply defined," — a conclusion in which 1 quite agree. 



I quote these remarks of Mr. Woodward (the bearer of a name so 

 long and honourably connected with the investigation of the Crag and 

 Glacial series of Norfolk) to show how complicated the question has 

 become, and how diverse the opinions on the subject still are. The 

 classificatory objections to Messrs. Wood's and Ilarmer's Bure- 

 Yalley Crag do not, however, affect the question of superposition, 

 on which their main contention on this point is founded. 



In 1387, Messrs. W. Whitaker and W. H. Dalton, in their 

 memoir ' On the Geology of the Country around Halesworth and Har- 

 leston' t, state that in the area they describe, the beds of the Pebbly 

 Series vary, and "to the west and north-west they change into tine 

 sands and loams, each exposure showing different peculiarities." 

 They express a preference for the use of the lithological name 

 instead of the geographical ones of Mr. Wood and myself, and leave 

 the question of the relation of the Pebbly Series to the Ghicial Drift 

 and Chillesford Clay or to the Pliocene below an open (luestion. 



The reasons for not pledging himself to the question of classifica- 

 tion are given by l^Er. Whitaker in a later memoir:}:. In this he 

 makes some pertinent remarks on the " Pebbly Series " and its 

 literature. In exijlanation of the various names and classifications 

 that have been proposed for these beds by diHerent writers, he 

 suggests that " It seems possible that anyone working southward 

 from the northern part of Norfolk might get into a somewhat dif-
