WESTLETON BEDS TO THOSE OF NORFOLK, ETC. 87 



graphical evidence in proof of their exact relationship to the associ-

In the following year Mr. F. W. Harmer gave a section of the 

 Yare Valley*, confirming the views of Mr. AVood ; and in 18()8 

 these gentlemen read at the Meeting of the British Association in 

 Norwich a joint paper, illustrated with a large map and local 

 sections, but of which an abstract only was published in that year t. 

 In this it was stated that the Pebbly Beds or Crag of Belaugh in the 

 Bare Valley, and the Crag of Weybourn and Cromer, were newer 

 than the Chillesford Beds, and that " the 'sands with pebbles' occupy 

 in the south of Norfolk and the north of Suffolk, the same place 

 relatively to the ' contorted Drift ' as is occupied on the Cromer coui-t 

 by the VVeybourn Sand (or ^-called ' Crag' of the Cromer coast), 

 the Cromer Till, and the indenting sand (or bed C). These pebhle- 

 beds may thus represent in time either the whole or any one of the 

 formations A, B, and C ; or they may form merely the closing bed 

 of the true Crag Series, in which case the VVeybourn sand, the 

 Cromer Till, and bed C are entirely unrepresented in the south of 

 Norfolk and north of Suffolk." On the next page A is stated to 

 represent the Weybourn Sand with shell patches resting on the 

 Chalk, and " passing up by interbedding into B, the Cromer 

 Till or Lower Boulder-clay," and C the sands which indented into 

 " a deeply-eroded surface of the Till." 



In 1869 a paper was communicated to the Norwich Geological 

 Society by Mr. Harmer J, which gives a clearer exposition of 

 Mr. Wood's views, and is accompanied by a list of the Belaugh shell's, 

 including these of Weybourn {postta, p. 03)§. In this Mr. Harmer 

 says that " the only doubt felt by Mr. Wood and himself in con- 

 nexion with the beds of the Crag Series in Norfolk is, whether or 

 not the pebbly sands of Belaugh and Weybourn are identical with 

 the Pebbly Sands and Pebble-beds which overlie the Chillesford Clay 

 in the neighbourhood of Norwich, of Ladden, of Halesworth, and 

 of Beccles, or whether they do not form a still later deposit," ..." so 

 that for the present they do not express any opinion on the identity 

 of the Pebble-beds in these two areas." 



In other papers published in 1869 || those gentlemen again give 

 the succession of beds about Norwich, and state that the Pebbly 

 Sands and Pebble-beds (a name which they were the first to adopt), 

 which succeed to the Chillesford Clay, "expand northwards into the 

 Weybourn Sand and Boulder Till of the Cromer-CUiT section ; this 

 bed is unconformable to the Crag and Chillesford beds, is paheonto-
