WESTLKTON UKDS TO THOSE OF NORFOLK, ETC. 131 



I omitted to notice whether chert and ragstone were present, 

 nevertheless the composition and character of the sands and 

 shingle are, I think, of the Westleton type. Both flint- and quartz- 

 pebbles occur, it is true, in the lied Crag *, but never in such 

 numbers, or proportion, as to form a compact bed of shingle like 

 that of Westleton.

b. Bluish Boulder-clay exposed in another pit a short distance higher 



on the hill. 



c. Bright yellow and white micaceous sands, fine at top, coarse below, 



succeeded by fine gravel or shingle. The sands show oblique 

 lamination, and contain concretions or balls of soft iimouite, 

 some 1 foot in diameter 25 



d. Layer of large flints, angular and rounded. 



The railway between Sudbury and Mark's Tey exposed .some in- 

 teresting sections. The first deep cutting, 2 miles south of Sudbury, 

 showed 5 or 6 feet of ochreous flint-gravel and sand, overlying frpm 5 

 to 10 feet of greyish-bUie clay (Glacial), of which the lower part was 

 finely laminated. Beneath this were 4 or 5 feet (base not reached) 

 of white and yellow sands with seams of small shingle (Westleton?). 

 The Lamarsh and other smaller cuttings were through Post-Glacial 

 brick-earth and gravel. Between Bures and Chappie, the cutting 

 passed through 12 feet of a blue Boulder-clay, separated from 10 

 feet of a brown Boulder-clay by 2 feet of ochreous gravel. Belov\' 

 the Boulder-clay was a bed, 4 feet thick, of ochreous gravel, under 

 which were 7 or 8 feet of white sand and gravel (Westleton). 



But the most important cutting was that between Chappie and 

 Mark's Tey. It extends for nearly a mile, and reaches a depth of 

 from 20 to 25 feet. At the two ends, the section exposed from 8 to 

 10 feet of Boulder-clay overlying Westleton Shingle, but in the centre 

 resting on London Clay. The whole section is given at length in 

 PI. VII. fig. 7. A small enlarged portion is given below (fig. 7).
