YORKSHIRE GLACIAL GEOLOGY. 



Whilst we are proud to think that Yorkshire, and Yorkshire 

 geologists, have occupied so great a part of Professor Bonney's 

 address, we rather fear the limited area makes his remarks too 

 parochial in character, and hardly of world-wide interest. 

 We were a bit surprised to find it stated however (p. 24), that 

 "' the so-called moraines near York (supposed to have been left 

 by a glacier retreating up that Vale), those in the neighbour- 

 hood of Flamborough Head and of Sheringham (regarded as 

 relics of the North Sea Ice Sheet), do not, in my opinion, shew 

 any important difference in outline from ordinary hills of sands 

 and gravels, and their materials are wholly unlike those of any 

 indubitable moraines that I have ever seen or studied in photo- 

 graphs.' All we can say is that we are sorry the Professor's 

 experience of moraines is so limited. We thought he had seen 

 several. Dozens of other geologists, whose names even Pro- 

 fessor Bonney would admit were amongst the front rank, have 

 seen and described these resemblances over and over again. 

 The way also, in which Professor Bonney dismisses in a few 

 words, the ' so-called ' overflow channels in Cleveland ; Lake 

 Pickering, etc., is typical of the ' judgment ' throughout the 

 address. Personally, we consider the Rev. Professor would 

 have made a much better advocate than a judge ! 



BIRDS. 



Great Crested Grebe in Yorkshire. — Rather more than 

 twenty Great Crested Grebes are to be seen on the large lake 

 at Castle Howard. All of them bred there this year, the bad 

 weather appearing to have suited the successful nesting of this 

 .beautiful bird. — Sydney H. Smith, York, September i6th, 1910.

FLOWERING PLANTS. 



Gentiana Pneumonanthe at Clapham, Yorkshire.— This 

 plant, which seems to have been overlooked for many years, 

 still flourishes in fair quantity near Clapham Station. Lees' 

 Flora says : — ' A quarter of a mile beyond Clapham, in a field 

 going the middle way to Engleton : Mr. Newton ; Ray, Syn., 

 III., 274 (1724) ; Derh. Litt., 222 (1718). It is lost between 

 Clapham and Ingleton, where Mr. Newton observed it, as Mr. 

 Thornbeck informs me : Blackst., Spec. (1746).' It is interest- 

 ing to know that it is still in the district. — A. R. Sanderson 

 and C. A. Cheetham,
