ME. BEENAED SMITH ON THE 



[Sept. 19 1 2, 



This deposit presents a characteristically patchy appearance in 

 ploughed fields. 



In the beckside, 600 yards south of Whicham Mill, a stony clay 

 rests unevenly upon a deposit containing strips of red and chocolate- 

 coloured laminated clay and warp. In other places 2 feet or more 

 of red sandy clay is seen. 



At levels below 100 feet, shingle, consisting of un weathered 

 slate, is mixed in a heterogeneous way with weathered slate-debris 

 and patches of red, purple, or greyish clay. The clay breaks up 

 into small cubes, somewhat like the fine loam of a river-deposit.

At the north-eastern extremity of the lake, close to Seathwaite 

 Bridge, between 150 and 180 feet O.D., there is a deposit, probably 

 of a deltaic nature, formed by waters from glacier-tongues which 

 lingered in the hollows on both sides of Baystoue Bank. It is 

 composed of boulders with interstratified beds, a foot or more in 

 thickness, consisting of rapidly alternating layers of yellowish sand, 

 silt, and red warp. The dip observed at one point was in a south- 

 south-easterly direction. This deposit may, however, have been 

 formed, at a slightly earlier date, in a temporary lake enclosed 

 between the two above-mentioned ice-tongues when they were 

 confluent. 



Another fluvioglacial deposit at Sandholes Wood, about 500 yards 

 from the Gill-Scar outflow (p. 437), is not quite so easily explained.
