no DESCRIPTION OF THE STRATA. 



place ; for on proceeding a little distance from the place examined, 

 we may find an almost entire revolution in the number and order of 

 the strata. In some instances, however, the series proceeds to a 

 considerable distance, without being much disturbed. 



As the alternating beds are subject to such transitions, we are 

 not to expect any uniformity in their respective qualities. The sand- 

 stone is of all descriptions; hard, and soft; fine gi-ained, and coarse; 

 schistose, and massive; white, grey, yellow, mottled, blue, light 

 brown, and dark brown. The schist is, in some instances, blue, 

 sandy, and micaceous; in others, yellowish and ochrey; in others, 

 black, fine grained, and highly bituminous ; and not unfrequently, the 

 same bed contains shale of various qvialities blended together. A 

 mixture of sandy and bituminous shale is very common. The coal is 

 also of various descriptions ; some of it being little superior to the 

 bituminous shale, while other parts, particularly in the middle of the 

 seams, are of an excellent quality, breaking like the best coal, into 

 cubical fragments, with smooth shining surfaces. It is scarcely ne- 

 cessary to add, that the ironstone of this series is as variable as the 

 strata in which it is imbedded. 



Having made these general observations on the beds of this se- 

 ries, let us proceed to notice their order and appearance in some 

 particular places, especially in the sea cliffs; and to mention some of 

 tlie more remarkable beds, both there and in the interior. 



To shew the connection of this series of beds with the strata 

 above them, it may be proper to give the folloMdng list of the whole 

 strata at Cloughton wyke, including those already described. We 

 find there, 



1. Thick beds of sandstone, forming the upper part of the cliff at 

 tlic south-east cheek of the bay, or wyke. 



2. A considerable bed of shale, which, with the sandstone, runs 

 out towards the inner part of the wyke.
