204 YORKSHIRE NATURALISTS AT HOLMFIRTH. 



what it is hoped will turn out under cultivation to be Cystopteris 

 fragilis Bernh., a fern recorded for Ramsden Rocks in the neigh- 

 bourhood. Other noteworthy plants gathered during the day near 

 Bilberry Reservoir and at Harden Moss being Cardamine amara L. 

 (very fine specimens of the purple-anthered bitter-cress), Salix 

 aurita L., Carex pracox Jacq., C. pilulifera L., Nephrodium filix-mas 

 var. borreri Newm. (with several forms ranging from the type to the 

 densely-scaled rachis and bright golden yellow fronds of true borreri), 

 N. oreopteris Desv. (luxuriant and typical), Polypodium phegopteris L., 

 and P. dryopteris L. 



In the absence of Mr. M. B. Slater, F.L.S., Cryptogamic Secretary 

 of the Section, Mr. C. P. Hobkirk reported that the following 

 mosses were found : — Dichodontium pelluddu/u, Dicranella squarrosa, 

 D. heteromalla, Ceratodon purpureas, Philonotis fontanel, Funaria 

 hygrowetrica, Bryum argentcum, Milium pundatum cum fr., Brachy- 

 therium rivulare, Plagiotheaum undulatum (all more or less common 

 species). Hepatics : Diplophyllum albicans, Nardia scalaris, Junger- 

 mannia barbata (all sterile, the three latter sent to and determined by 

 Mr. Slater). Algae, determined by C. B. Crawshaw and C. P. Hobkirk : 

 Conferva tenerrima, Ulothrix tenerrima, U. variabilis, Spirogyra 

 flavescens, and a few scraps of Spirulina tenuissima. 



The Secretary of the Geological Section (Mr. S. A. Adamson, F.G.S.) 

 writes: — The geologists had an unrivalled opportunity of studying the 

 geology of the wild and romantic moorland district lying south-west 

 of Holmfirth. The picturesque glens or gorges (locally termed 

 doughs), each with its little rivulet draining the lofty watershed of 

 the eastern flanks of the Pennines, often display on their sides good 

 sections of those divisions of the Millstone Grit series known as 

 the Third Grits and the Kinderscout. The party were ably led by 

 Mr. Joseph Field, of Huddersfield, who has closely studied in detail 

 the geology of the district ; and they further had the advantage of 

 the well-known experience of Mr. James Spencer, of Halifax. The 

 temperature of the day was well suited for the arduous ascents which 

 had perforce to be made here and there, as a cool and bracing wind 

 prevailed ; the fierceness of the sun's rays of the previous week was 

 now neutralised by the grey and leaden clouds which swept slowly 

 across ; these were, too, in unison with the bleak and rugged scenery 

 all around. 



The party on leaving Holmfirth Station passed through the 

 devious windings of the narrow streets, pausing at the bridge to note 

 the level the waters attained on that fateful day in 1852, when the 

 unrestrained torrents of the Bilberry Reservoir inflicted so much 

 devastation and death on this peaceful valley. The road was now
