The last-named, a comparatively rare plant, and un- 

 doubtedly the find of the day. It occurs in only fourteen 

 out of the one hundred and twelve counties into which 

 Britain is divided in the "London Catalogue." In Volume 11. 

 of the Natural History Transactions it is referred to on page 

 123, when it is stated to show a preference for lead mines. 

 Only one station in Weardale is given, somewhat higher up 

 than we found it, and on the other side of the stream, but no 

 doubt it has spread since Volume II. was published. 



The Bird Cherry and Plane Trees were in full bloom. The 

 Elm and Willow were in fruit. 



In addition to the birds I have already named, the follow- 

 ing were seen : — Chaffinch, Blackbird, Lark, Jackdaw, Pied 

 Wagtail, Wood Wren, and Cuckoo. 



In the bed of the river a considerable quantity of Basalt 

 has intruded itself.
