WESTLETON^ BEDS TO THOSE OF NORFOLK, ETC. 99 



also describes the various interpretations* to which these beds 

 have given rise. 



As there is little positive evidence of ice-action during this period, 

 it is interesting to note the discovery, recorded by Mr. "Whitaker 

 (p. 77), of a wedge-shaped block, 13 x 13 x 19| inches, of a mica- 

 ceous quartzite in the pebbly gravel at Easton. I noticed in 1869 

 in a farm-yard near Eeydon, a rather large boulder of granite, 

 which may also have come from these beds. 



At Easton Bavant the Chillesford Clay is well marked with its 

 characteristic shells ; but at the extreme north end of the cliff, 

 near Covehithe, there are indications of a change. Some trenches 

 opened at the base of the cliff a few years ago exposed the section 

 annexed (fig. 2). 



Eig. 2. — Section in Covehithe Cliff, north of Easton Bavant, 



feet. 



a. Dark sandy soil 2 



b. White pebbly sands (Westleton) indenting into c 3 



c. Irregular white and yellow sands 4 



d. Laminated brown clay 4 



e. Irregular carbonaceous band ^ 



f. Laminated grey clay (Chillesford?) 6 



^. Fine gravel and sand 2 



k. Shell-bed (fluvio-marine) 24- 



Here the Chillesford Clay is unfossiliferous, and is overlain by a 

 thin seam of carbonaceous matter succeeded by two beds of lami- 

 nated clays and sands, also without fossils, on which rest the sands 

 and shingle of the Westleton Beds. The beds c to e may represent 

 a commencement of the Eorest Series, and would thus show its 

 relation to the Eluvio-marine Crag (g). 



Another point of interest in this section is the presence of small 

 pockets or indents of sand filling hollows on the top of the laminated 

 bed c, on which rest the horizontal seams of sand and shingle h. 

 The sand in the holes is the same as that of bed h. Mr. Whitaker 

 (p. 75 of his Southwold Memoir) has described similar small 

 contortions in these cliftsf, and Mr. C. lleid speaks of the 



* "Geology of the Suffolk Coast," Mem. Geol. Surv. 1887, pp. 57-59, G8-72. 



t It was possibly these contortions which led Mr. Wood to refer the sands 

 and loam in the upper part of the Covehithe cliff to the " Contorted Glacial 

 Drift."
