REPORT OF FIELD MEETINGS. 277 



All these I have gathered myself within the last few years. 

 It is possible that others have succeeded in their search after 

 species where I have failed, but it would be of great advantage 

 to botanical students if some such revision as I have indicated 

 could be made, bringing our local flora up to date. If some 

 individual with sufficient time and enthusiasm could be found 

 to do the work that would be the most satisfactory solution, 

 but, failing that, I do not see why the Natural History Society 

 itself should not undertake it. It is a work in which many 

 could co-operate, and to which I am sure many would be 

 delighted to give a helping hand, but some one must take the 

 initiative and be responsible for carrying it through. 



Geological Notes for a Visit to Rothley Crag. By Prof. G. A. 

 Lebour, M.A., M.Sc, F.G.S. 



Read at the Rothley Crag Field Meeting, 15TH Sept., 



1904. 



When, in 1867, I first began to geologize in Northumber- 

 land, it was customary to regard the " Great Limestone " as 

 the topmost bed of the Carboniferous Limestone series. The 

 beds next above were therefore regarded as forming part of 

 the Millstone Grit, and thus is explained the enormous area 

 which is assigned to that division of the Carboniferous rocks 

 in the older geological maps of North Eastern England. I 

 believe I am right in stating that the Rothley Crags and the 

 late Sir Walter Trevelyan were jointly responsible for this 

 view, though its actual publication was due to Professor John 

 Phillips. It was natural enough for Sir Walter, an excellent 

 and enthusiastic observer residing close by, having the 

 fine grit escarpments of Rothley and Shaftoe Crags con- 

 stantly before him, to conclude that the rocks which pro- 

 duced them were the representatives of the first coarse grit, 

 or " Kinderscout " bed, which in Derbyshire and in West 

 Yorkshire immediately follows the shales, sandstones, thin
