204 Slather : Dr. Roive on the Yorkshire Chalk. 



and note also the author's striking- way of putting- things, we 

 can excuse the seeming overstatement of the case. 



Speaking of previous workers in the Yorkshire area he says: 

 ' Dr. Barrois' great work is the only one which contains a 

 serious attempt to grapple with the zonal problems of this 

 coast, and for once, we must frankly own, we cannot follow him 

 in his data or conclusions.' This estimate of Barrois' work, we 

 imagine, will not surprise East Yorkshire geologists, for in 

 several important particulars his conclusions have never been 

 accepted by local observers. Possibly it is to this work Dr. Rowe 

 refers when he mentions the ' legendary ' side of the subject. 



\Yith regard to the special difficulties of Flamborough Head 

 geology. Dr. Rowe says ' that this section presents many 

 physical difficulties we readily admit, but we question if they 

 are as insuperable as has been maintained.' This remark 

 apparently applies to some other ' legend ' for which we are 

 quite sure Yorkshiremen are not responsible. As might be 

 expected the Flamborough Head sections vary in difficulty, 

 some being exceedingly difficult to work and others extremely 

 easy. In a general way it may be said that there are two 

 difficulties which collectors from the Yorkshire Chalk have to 

 face, (i) that arising from the hardness of the rock and the 

 paucity and bad preservation of the fossils, and (2) the 

 inaccessibility of many miles of cliff on the northern side of 

 the headland. Equipped with probably an unrivalled know- 

 ledge of the plentiful and comparatively easily determinable 

 fauna of the Southern Chalk, Dr. Rowe has been able to deal 

 with the first of these difficulties far more thoroughly than any 

 worker who has preceded him in Yorkshire, and has achieved 

 the remarkable results so clearly shown in the paper before us. 

 On the other hand, the cliffs of Buckton and Bempton are still 

 unconquered, and along the long and lofty line of weathered 

 cliff' faces between Crow Shoot and Thornwick the Guillimot 

 and the Razorbill still hold their court undisturbed .by the 

 geologist. However, we must not overlook the excellent use 

 Dr. Rowe has made of the poor and not by any means easy 

 section at Crow Shoot, the successful interpretation of the over- 

 thrust fault near Kit Rape's Spot, and the viking-like raid and 

 the 'lifting' of the anticipated and coveted Micraster near Brail 

 Head. 



On the other hand, the whole of the cliff sections on the 

 south of the Headland can be approached at almost any condi- 

 tion of the tide, and present no manner of physical difficulty to
