WESTLETON BEDS TO THOSE OE NOEEOLK, ETC. 125 



Crag sand " *. Two pits near East Bridge where it is to be seen 

 are also noticed t. Mr. S. Wood, on the other hand, was of opinion 

 that most of these gravels, as well as those of which we shall have 

 to speak in East Essex, belong to his Middle Glacial. 



Eastward of this place the shingly sands pass apparently over the 

 Crag of Sizewell Gap ; while to the westward they form part of the 

 sandy commons and heaths of the Snape and Tunstall districts, but 

 definite sections are wanting. 



To the west of Wickham Market, a bed of white gravel and sand 

 is worked in several small pits ; and in one near Easton indistinct 

 traces of shells are observable in some thjn intercalated seams of 

 ironstone. The furthest point inland here at which I have seen 

 the Westleton Eeds is under the Boiilder-clay at Erandeston (fig. 2). 

 There may, however, be a little doubt about this determination.

b. Dark bluish-grey Boukler-clay. 



c. Light-coloured coarse quartzose panel with seams of grayel consisting 



largely of flint-pebbles and some of white quartz, with a few fragments of 

 shells. 



At Ufford Bridge, between Wickham Market and Woodbridge, the 

 Westleton Shingle rests on the Bed Crag, with the Bouldcr-clay 

 above it. At Kyson or Kingston, near AVoodbridge, the railway- 

 cutting exposed a fine section of the Red Crag and overlying sands, 

 capped by a bed of Westleton Shingle. The following are the 

 local particulars ; a general section is given in Plate VII. fig. 8 §.

 I I give dates, because in all probability many of the sections no longer 

 exist.
