CHALK AND DKIFT IN MOEN AND KUGEN. 



309 



fragments of the clay were seen low down on the southern side of 

 the gully. 



(3) Confirmatory evidence is obtained from another section (fig. 2) 

 south of the last, and in the neighbourhood of Sandskredsfald. 

 Here we see the grey clay lying in a similar manner, but more hori- 

 zontally, beneath an overcurving mass of Chalk, and here also the 

 flexures in the latter are not directly connected with the common 

 surface of the two.

1 = Clialk. 



2 = Clay. 



2' = Hollow in Chalk, from which 



the clay %.s fallen. 

 8 = Slopes, overgrown. 



The foregoing sections may suffice as examples, but others yielding 

 similar evidence could be produced from our note-books.^ The result 

 of our examination o£ this part of the coast may be summarized in 

 the f olio wit) g clauses : — 



(a) The Chalk dominates vastly over the clay. Along the beach 

 it may be traced almost continuously, and sometimes for over a 

 furlong without interruption even from a slip : the clay often being 

 a very limited and local phenomenon. 



(b) The Chalk, above or below the clay, is generally rotten and 

 stained yellowish-brown for a few inches (seldom more than 6), 

 and for about the same thickness tiny streaks of chalk occur in 

 the clay : this banded clay being occasionally squeezed up into 

 hollows in the Chalk, 4 or 5 inches deep. 



(c) The clay very often appears to form a mere facing to the 

 Chalk, or to fill a semicylindrical or wedge-shaped cavity in the 

 latter, the Chalk beyond this cavity being perfectly continuous.
