CiRC. No. 132. 



Derwent and its tributaries, gives good opportunities for the examination of the 

 Middle Oolites from the Kelloway Rock to the Upper Calcareous Grit. The beds 

 of the Coral Rag exposed in the quarries of Sufiield, Silpho and Ayton are very 

 fossiliferous, and will afford excellent opportunities to the collector. Forge Valley 

 is an interesting ))hysical feature, being a gorge cut by the Derwent when its drain- 

 age valley at Scalijy was stopped during the Ice Age by the North Sea glaciers. 

 Owing to the same cause the exit at Filey was closed, the Vale of Pickering became 

 a lake, and the waters finally found their way over the low watershed at Malton 

 and became tributary to the Ouse. 



BOTANY. — The Botanical section will be officially represented by its Secre- 

 taries, Mr. John Farrah, F. L.S., Mr. J. J. Marshall, and Mr. Charles Crossland. 



Flowering- Plants. — Mr. E, R. Cross says :— As the district is rich in natural 

 beauty so also it is abundantly rich in flowering plants. Not far from Hackness 

 grows the rare May lily {Maianthcniuni bifolia), robust and healthy, blooming 

 in abundance from year to year. The valleys running at right angles from Hack- 

 ness abound in many species of fern ; amongst others are Polypodiiiin phegopteris, 

 P. viilgare, P. dryopteris, Aspleniicm virl.ie, A. trkluvnanes, and A. ruta- 

 imtcraria, also Osmnnda regalis, almost gone, alas, by the depredations of the fern 

 gatherer and the so-called botanical fern lover. Whilst above on the moors Botry- 

 chium lunaiia and Ophioglossiim vnlgatum are abundant. Near Langdale End the 

 beautiful dwarf Cornel {Cornus 5«c.:zVa) reaches its southern limit, and will now be 

 looking its best. In addition the following plants should be seen, Actcea spicaia, 

 Aqnilci;ia vit-lgaiis, Hypericum montanuin, Eiiony/mts Etiropceiis, Rhamims cathar- 

 tictis, Pruniis padus, Chrysosplenium alterni folium, Anteimaria dioica. Campanula 

 latifolia, Pyrola media, P. viinor, Gentinna carnpestris, Carex digilata. On the 

 moors in a pine wood is a locality which some years ago was given for Linnaa 

 borealis, and although it has not been found recently a thorough search should be 

 made, as being rather out of reach it is not often visited by botanists. Near here 

 also on the moor a few specimens of the dwarf Twayblade {Listera cordata) can 

 always be found by careful looking.
