At the High Force, other naturalists from Durham County 

 exchanged courtesies, and we were able to examine several 

 species which they had gathered earlier in the day before 

 the rain stopped investigations. Amongst those inspected 

 were Viola lutea and Potentilla fruticosa. 



The excursion fixed for July 11th, at Swainby, was a 

 duplication of the one at Middleton — Jupiter Pluvius inter- 

 vening, and by ubiquity spoiling it. Remarkable features 

 noticed on the tramp from the Station to Swainby were the 

 immense quantities of Agrimonia eupatoria on each side of the 

 road, the Bryonia Jioica on the hedges, and the luxuriance 

 of the Lonicera periclymenium, which in one spot on the 

 slope of Whorl Hill grew so densely that it some distance 

 away the hedge presented a patch pf crimson and gold. 

 This phenomenon was only noticeable in this district, and 

 the writer wonders whether the geological formation had 

 anything to do with it. This leads me to suggest the wisdom 

 of mapping out the various localities according to their 

 soil and keeping a record of the plant life of each particular 

 soil. For instance, round Stokesley there are distinct lines 

 of separation between the various formations — the Trias 

 (Red and Green Marls and Gypsum), the Lower Lias (Shales) 

 Alluvium, Rhaetic bed outcrop, and the Whin Dyke, and 

 I have noticed a considerable diversity of growth. 



I was prevented from attending the meeting at Sleights 

 for the Falling Foss, therefore my knowledge of what took 

 place is limited, but from my experience of the Falls in 

 Teesdale, I should imagine the growths of the Cryptogams, 

 or so-called flowerless plants on the wet rocks would be 

 plentiful and worthy of investigation. 



The last meeting of the season at Castleton, on September 

 5th, produced a fairly good muster, but the weather again 

 somewhat marred the enjoyment. The Quarry by the 

 Station proved interesting, the Cheiranthus cheiri and 

 Matricaria parthenium thriving in the insterstices of the 

 rocks. The walk across the moor produced nothing of 

 interest, except the abundance of Calluna vulgaris {alba) 

 Drosera rotundifolia and Empetrum nigrum, as it proved to be 

 the period when vegetation is on the wane.
