34^ Yorkshire Naturalists at SedbergJi. 



at the base of the Carboniferous rocks in the Sedbergh district, 

 but it varies in several respects from the red one mentioned, 

 and in Nor Gill the relationship of the two is clearly seen. 

 There is no gradual passage from the red deposits to the over- 

 lying rocks, and they seem to terminate abruptly, and are 

 succeeded by alternations of grey, or greenish, conglomerate, 

 pebbly limestones, and calcareous shales, the derived material 

 getting gradually less in quantity as a way is made up into 

 the beds of Carboniferous hmestone, which here is tilted at a 

 very high angle by the proximity of the Dent Fault. 



On the third day the party visited Spen Gill, which exhibits 

 probably the most complete section known of the upper beds 

 of the Bala series and the lower Silurians. Owing to the ex- 

 tremely wet conditions prevailing it was difficult to trace out all 

 the beds, but a good idea of the section was obtained, and 

 numbers of characteristic fossils found. The volcanic rocks 

 of Wandale and Odd Gill were also visited, as was Helm Gill 

 in the Dent Valley, all with satisfactory results. 



A section worthy of mention was examined near the Golf 

 Club House. It consisted of a large surface of limestone, 

 grooved and striated, precisely as if by glacial action. Some 

 of the grooves were quite deep. Immediately upon them, 

 however, rested another bed of limestone, under which the 

 strife extended. It was apparent that the polished and grooved 

 surface was caused by land-shps, the direction of the grooves 

 being down-hill. 



The botanists found a rich field, and were well pleased with 

 the abundance of rare and beautiful forms. They investigated 

 Cautley Spout, Howgill, Marthwaite and Killington. For 

 this section Mr. Ingham writes : — 



In addition to the Flowering Plants seen owing to the 

 information kindly given by Mr. John Handley, there are two 

 worthy of notice that came under my own observation. 



Thalictrum montamim Wallr. is a small and distinct Meadow 

 Rue growing on the rocks well up Cautley Spout. This species 

 is given as growing on Dalton Crag in the ' Flora of West 

 Lancashire.' 



Euphrasia Rostkoi'iana Hayne was abundant on the banks 

 of the River Lune. It was a striking Eye-bright with its large 

 size and large flowers. I sent a specimen to Mr. Wheldon, of 

 Liverpool, and he at once named it E. Rostkoviana. and gave the 

 following characteristics (i) Corolla lengthens after flowering ;
