This coal seam, beneath the gray oolite, is pretty extensively 

 wrought in the interior moorlands, as at Maybecks on the Sneaton 

 estate near Whitby, and in Danby beacon. The strata which come 

 below these cannot be well traced towards Haiburn Wyke, though the 

 cliff is three hundred and thirty-one feet high, because of a slip or 

 sunken portion of the precipice, much overgrown with shrubs and dis- 

 guised by loose blocks. There is a dislocation, perhaps a double one, at 

 Haiburn Wyke, and I am not certain that the sandstone beds on the 

 opposite sides are correctly referred to their respective relative situa- 

 tions ; but the section was drawn after three careful examinations of the 

 place. If it be correct, there are two faults running one on each side of 

 the little insulated cliff, and raising the strata a few yards on the south 

 side. 



THE cliffs which begin on the north side of Haiburn Wyke are 

 loftier than any which have hitherto claimed our attention. They con- 

 tinue rising with altitudes of two hundred and ninety-six, three hundred 

 and eighty-seven, and four hundred and ninety-seven feet, to the High 

 Peak which is about five hundred and eighty-five feet above the sea. In 

 the middle of this high range, the uppermost rock is the carbonaceous grit- 

 stone so frequently mentioned, and below it a series of limestone, shale, 

 and sandstone, corresponding to those already enumerated at Cloughton 

 Wyke. Lower beds than those also appear at the northern and southern 

 extremities, but are obscured in the middle by what seems to be a very 

 extensive slip of the superior heights, forming an " undercliff." 



As in a part of the Stainton cliffs the carbonaceous sandstone is seen 

 lying upon the oolitic series, whilst at Blue Wick below the Peak the
