Notes on the Brandeshurton Kame, Yorkshire. 825 



away, so that there is little opportunity of observing the dip of the 

 beds. The section, however, gives clear evidence of deposition by 

 water. The coarse gravel has a suggestion of stratification, but all 

 the fine gravels show distinct bedding planes which are horizontal. 

 The sands lie horizontally between the gravels and some show 

 current bedding, particularlv the sand immediately beneath the 

 clay. The clay and coaly layers are both horizontal. Tracing the 

 stratification towards the margin, the clay is seen to thin out and 

 droop. Also the beds did not persist, e.g. the 4 feet of coarse gravel 

 passed mio a very fine sand without shell fragments and with no 

 false bedding, but it was not possible to observe the junction nor to 

 trace any bed far, as the pit is in the centre of the hillock and the 

 edges are smothered in debris. 



Though this pit gives no indication of dip, a trench cut 

 longitudinally in the ridge between Coneygarth Hill and Starcari 

 Gate shows a very small dip to the west along the ridge and a very 

 gentle inclination towards the margin. This trench shows no sand, 

 but only thin alternations of coarse and fine gravel whose composition 

 is the same as that in Coneygarth Hill. 



There is no seasonal banding in the Coneygarth Hill pit, and that 

 it does not occur in the ridge is shown by the absence of alternations 

 of broad and narrow patches along its course, for it remains parallel- 

 sided throughout. The existence of Coneygarth Hill is not due to the 

 presence of any particularly resistant band of gravel, since it is com- 

 posed of alternations of hard and soft horizontal beds which are 

 scarcelv cemented at all. 



Section in Pit west of Starcaer Gate. 



This pit gives both transverse and longitudinal sections. The 

 longitudinal section shows a small dip to the west along the ridge.

False bedding is present, but is not very pronounced. The trans-

 of the ridge, and gives the above section. The section on the up- 

 throw side is : —
