430 Clapham : Its Geology and Natural History. 



Entomology. — Mr. G. T. Porritt writes : — With a keen, 

 piercing wind, as cold as in mid-winter, little was expected 

 entomologically. Polia chi was not uncommon on the stone 

 walls, but all of the palest and most ordinary form, the dark 

 varieties one is so familiar with in South-west Yorkshire, being 

 apparently entirely wanting. Peronea sponsana was common 

 in beeches ; and larvae of Boriihyx ruhi seemed to be also fairly 

 numerous on grass. The Trichopteron Anaholia nervosa was 

 abundant all along the river banks, where also a much larger 

 Halesus was seen, doubtless either radiatus or digitattts, but 

 the only specimen escaped before its absolute identity was 

 established. Other Trichoptera and Neuroptera included Lepi- 

 dostoma hirtum, Leiictra kldpaleki, Hemeiohius subnehiilosus, 

 H. liitescens, etc. 



Geology. — Mr. E. Hawkesworth writes : — There is much to 

 be said in favour of visiting areas in w^hich a simiilar succession 

 of rocks is exposed, at short intervals, thus making comparison 

 easier. Ingleton in 1906, Horton last year, and now Clapham 

 have afforded the members of the geological section oppor- 

 tunities of examining and comparing the pre-Carboniferous 

 rocks occurring in each district, and it is hoped that in 1909 an 

 excur- sion will be made to Sedbergh, then, with the exception 

 of one or two small exposures, the areas occupied by the 

 older rocks of the county will have been visited. 



Some of the geologists arrived on the Friday morning, 

 spending the remainder of the day in going over the route fixed 

 for the Saturday. About a dozen spent the week-end in the 

 district, and, with the addition of others who came for the Satur- 

 day, the section was very w^ell represented. When making 

 preliminary arrangements for the excursion, the writer casually 

 met Professor T. McKenny Hughes, M.A., F.R.S., F.G.S., 

 Woodw^ardian Professor of Geology in the University of Cam- 

 bridge, who took part in the Geological Survey of the district, 

 and for many years past has spent considerable time in elucida- 

 ting its structure. Eventually, after the circular had been 

 printed, he decided to be present. His explanation of the 

 geology, his general information about the district, his unfailing 

 store of humour and anecdote, will long be remembered by 

 those privileged to accompany him. 



Going east from Clapham, the first call was made at a grave] - 

 pit on the side of the hill near the Ingleborough Home Planta- 

 tion, just over five hundred feet above sea-level. The section
