BOOKS AND MAPS. — The whole district for investigation is comprised 

 within Sheet 6i (92 N. E. ) of the Ordnance Survey Map, which is published 

 coloured for solid geology. 



GEOLOGY. — This section will be officially represented by its Secretaries, 

 Mr. T. Sheppard, F.G.S., and Rev. J. Haweli, M.A., F.G.S. ; the Boulder 

 Committee by its President, Mr. Percy F. Kendall, F.G.S. ; and the Geological 

 Photographs Committee by Mr. Godfrey Bingley. 



Mr. Percy F. Kendall, F.G.S., writes that the steep hillside from Dacre Banks 

 up to the Brimham Rocks is an escarpment of the middle portion of the Millstone Grit 

 series, including the most important and persistent marine horizon yet recognised in 

 the Grits, the Cayton Gill beds, which are largely calcareous and yield an interesting 

 fauna, particularly rich in brachiopods. A small quarry by the roadside on the way 

 up to the Brimham Rocks exposes these beds, but the best fossiliferous exposure is 

 at Clints quarry, near Hampsthwaite station. There the prevailing fossils belong 

 to the genus Frodiictus, of which magnificent internal casts are obtainable, besides 

 well preserved shells bearing tubular spines with a fine nacreous lustre. The 

 Brimham Rocks themselves seem to have been etched out largely by wind erosion, 

 and may be relics of the glacial period when the country was not so well protected 

 by vegetation as at present. The glacial phenomena of Nidderdale have not been 

 adequately studied. He has seen a fine terminal moraine stretching across the 

 valley at Glasshouses, and below that the superficial deposits appear to be fluvio- 

 glacial and lacustrine in character. Nidderdale was dammed near Nidd Viaduct by 

 the glacier which came down Uredale, and a large lake occupied the valley for some 

 miles. Many interesting observations await the geological section. ; 



BOTANY.— The Bryological Committee will be officially represented by its 

 President, Mr. T. W. Woodhouse, F.L.S., and its Executive Member, Rev. W. 

 Fowler, M.A. ; the Bryological Committee by its Executive Member, Mr. 

 W. Ingham, B.A. 



Flowerings Plants and Ferns, etc.— In ' West Yorkshire,' 1878, pp. 296-7, 

 Mr. F. Arnold Lees writes that at Brimham, about the rocks and on the moors, 

 Corydalis claviadata, Vacciniumvitis-idcea, Trientalis, Digitalis purpiirea,Evipelr2im 

 tiigrum, Orchis incaj-nata^ Listera cordata, Habenaria alhida, Carex pilulifera, and 

 Lycopodiuni selago are to be found, although the Trientalis and Listera were even 

 then very rare. 



Mosses and Hepatics. — Mr. LI. J. Cocks writes that the district is one 

 which should pay for careful examination, and he recommends bryologists to pay 

 especial attention to the Fell Beck, from its sources in bogs on Pateley Moor to its 

 junction with the Nidd. South of the Ripon and Pateley road this stream soon passes 

 through sandstone, and here the rocks in its bed and the bordering woods should 

 yield a good number of Hepatics. Liochla:na lanceolata is a plant to be looked for 

 here, as it grows in a similar locality higher up the Nidd Valley. Brimham Moor 

 will afford several species of Sphagnum. From Brimham Rocks Teesdale records 

 (lygS) Andrei^a petrophila and GyDinoviitriiim concinnattcm, but it will be surprising 

 to learn that either of these montanes still survives there. Oticophorits brnntoni 

 occurs, in small quantity and barren, in rock crevices, and Schistostega osinundacea 

 in hollows under the high rocks on the north side. (This latter plant, however, is 

 much more abundant on Guy's Cliff on the opposite side of the Nidd). The 

 following also occur in the locality: — Georgia brownii, Fissidens piisilliis, Aniso- 

 iheciii?n squarrosum, Ca?npylopzis fragilis, Brachydontium trichodes, Ditrichum 

 hoiiioi/ialliiin, Grimmia trickopkylla, Glypko/nitrijtfn polyphylliim, AIniiim pseudo- 

 piindatum (bog behind the inn on Ripori road), Fontinalis squamosa, Pterygo- 

 phyllum lucens, Heterodadium heteropterum, Plagiothecium borreri, P. latebricola, 

 Ainblystegiutn cordifolium, A. giganteum, A. stramineum, aud Mylia taylori. 



It may be of interest to note that Sawley Moor (Yore Basin), which adjoins 

 Brimham Moor, is one of the few stations in which the rare and erratic Bnxbautnia 

 aphylla has been found. 



Fungi. — There are no records, but any specimens found should be sent to Mh 

 Chas. Crossland, F.L.S., at the Fungus Foray at Egton Bridge. 



Lichens and Algae. — No records. 



VERTEBRATE ZOOLOGY.— The Vertebrate Section will be officially 

 represented by its Secretaries, Mr. Riley Fortune, F.Z.S. and Mr. K. MacLean.
