THE 'YOREDALE' ROCKS OF NORTH DERBYSHIRE. 



Sir, — A few days ago I enjoyed the privilege of attending the 

 excursion of the Geologists' Association to North Derbyshire, and 

 I was impressed by the tenacity with which many of the members 

 of the party — including geologists of repute — adhered to the use 

 of the term * Yoredale ' for the strata seen in the excavations of 

 the Derweut Valley Water Board and elsewhere. 



In Derbyshire and North Staffordshire there is a well-marked 

 group, consisting of dark shales with thin limestones and sandstones, 

 situated above the massive Mountain Limestone and below the 

 lowest of the Millstone Grits. 



I should like to ask those who still consider the name ' Yoredale ' 

 to be applicable to this group in this area to be so kind as to state 

 the foundations of their belief. Are the palseontological or the 

 litliological characters their guide ? 



From either point of view, I think it has been clearly shown 

 that the deposits in question are sufficiently differentiated from the 

 typical Yoredales to justify a distinctive appellation. 



The name * Yoredale ' is a good one so long as it is confined to 

 the type of deposit that exists in and about the Yorkshire Yoredale 

 district ; in addition to its historic intei'est it has an intrinsic value 

 in connoting a set of conditions pre-eminent in that area ; but to 

 continue to use it for this rock in North Staffordshire and Derbyshire 

 is to maintain a stumbling-block in the way of all workers who are 

 not familiar with the two areas. 



The natne ' Pendleside Group ' has been proposed by Dr. Wheelton 

 Hind and myself, but if there are objections to this there still 

 remains the choice of the non-committal ' Shales with limestones ' 

 and ' Shales with sandstones ' of the Geological Survey. 



Call them what you will ; but if the name Yoredale is to stand 

 for these beds let it be on the basis of solid pal^ontological evidence.

NEOLITHIC FLINT FLAKES AT HOPE'S NOSE, TORBAY. 

 Sir, — On the 4th of last May I found four flakes or chips of flint 

 about two feet deep in the earthy head or landwash capping the low 

 cliff on the eastern side of the raised beach at Hope's Nose. The
