DESCRIPTION OF THE COAST. 



lias appears, we obtain by uniting the observations the following section 

 of nearly the whole of the moorland series of rocks. 



Feet.

Carbonaceous grit, containing black shale in lumps and layers, 

 bits of Carbonized wood, and striated culms, but apparently 

 different from those of High Whitby. This rock is quar^ 

 ried on the edge of the cliff.

Mostly sandstone beds, forming a rock about sixty feet thick 

 which may be traced without interruption from Haiburn 

 Wyke to the summit of the cliff at the Peak ; and from 

 that point it appears on many of the cliffs to the north- 

 ward, and constitutes what is called the " cap rock" of 

 the alum shale. 



The series below, to the lias, varies much in the arrangement of the 

 beds of sandstone and shale, and still more in their aggregate thickness. 



Feet. 



200 



A series of shales and sandstones in very frequent alternations, the former pre- 

 dominating so as to cause the cliff to waste, and generally to slope from the cap 

 rock above to the sandstone series beneath : in a part of this series at Haiburn 

 Wyke lie fossil plants resembling cycadeae, ferns, equiseta, &c.
