IN PART OF NORTH-WESTERN ESSEX. 2x5 



as it seems a characteristic of the ^^'estleton Beds, it is worth while 

 here to ask two questions — (i) Is it derived from the waste say of 

 the Chillesford Clay? (2) Has it ever been known to occur in the 

 Glacial series ? 



In passing north-east towards Stehbing Downs we pass over a 

 ridge of some elevation, say 250 feet above O.D., and more than 

 two miles across. It is a matter of speculation as to whether the 

 Westleton Beds may not enter largely into the composition of this 

 ridge. Yet again it may be due to a fold in the I>ondon Clay. 

 Towards its south-eastern end, at a point one-eighth of a mile west 

 of " Throws " Farm, the Drift is about sixty feet in thickness, and the 

 London Clay two hundred feet. (See letter from Mr. Hasler, 

 Appendix.) 



The sand-pit at Stebbing Downs, to which I now call attention, 

 has furnished some good evidence as to the Pre-glacial age of the 

 gravel and sand. It is shown as "Sand-pit " in the Geological Map. A 

 nodule of clay containing shells was taken from there a few years ago, 

 and submitted to Prof. Keeping, of Cambridge, who pronounced 

 them to be of " Crag " age. Unfortunately the relic has since been 

 lost.- The exposure there is now very fine, and is as under : — 

 Post-Glacial drift .... 8 feet. 

 Westleton Pebbly gravel . . . 4 ,, 

 Finely bedded yellow sand, with mica 



scales, not bottomed . . . 8 ,, 



A shallow pit, one hundred yards to the north-east of the above pit, 

 shows only Westleton gravel overlaid by dark soil of about one foot. 



Westleton gravel appears to underlie the mount and stream at 

 Stebbing Park. A small exposure shows that it extends to the level 

 of the stream. It is not thus shown on the Drift Map, being 

 included in the London Clay. 



About a mile to the east of Bran End, near the letter " \V " in 

 "White House" (one-inch map), there are two gravel pits known as 

 "Blewitt's." One is in the lane, and the other in the field adjoining. 

 That in the lane is a long semi-circular exposure, showing six feet of 

 Westleton shingle overlaid by two feet of Boulder Clay. The pit in 

 the field shows also six feet of Westleton shingle overlaid by four feet 

 of a purple sandy clay of uncertain age. A depression in the lane 

 at a lower elevation shows bright yellow sand with mica scales. 



2 This specimen of Crag from the .Stebbing pit was described by the Rev. Edward Gepp in a 

 note in our " Journal of Proceedings " for April 26th, 1884 (vol. iv., p. xcvii.). — Ei).
