Anniversary Address. 45 



Archibald. Jerdan, — Old Jedward, — these are names to conjure 

 with, and the full story of any one of them would occupy more 

 than the whole space devoted to this address. Besides, is not 

 their chronicle written in Jeffrey's " Eoxburghshire," in whose 

 pages one may read, and learn that the peace-loving members 

 of the Berwickshire Club were that day driving over scenes, 

 where almost every field had witnessed the shedding of blood 

 in hot strife, and every name recalled a deed of heroic or of law- 

 less daring. As the elevation increased the umbrageousness of 

 the woods became less marked, and the country more open, while 

 it was also evident that we had passed from the warm red sand- 

 stone to the harsher greywacke. Distant prospects also opened 

 up from the higher reaches of the road, the toll bar on the ridge 

 of Carter Fell, among other landmarks, being discernible. 



The geological character of the upper Jedwater district being 

 comparatively unknown, I gladly avail myself of the toUowing 

 particulars from Professor James Geikie, contained in a letter 

 from him to Mr Hardy, — being the results of the Government 

 Survey under his charge. The Ordnance geological map of Eox- 

 burghshire is now, it is understood, in the engraver's hands — 

 and Dr. Geikie has written the accompanying memoir, so that by 

 and bye the members of the Club will have access to an adequate 

 guide-book for prosecuting inquiries of this description. 



" On going up the Jed above Jedburgh you pass first over the 

 red sandstones and crumbling shales and clays, which are too well 

 known for me to add any notes here. You will remember the 

 classical unconformabilities of these beds upon the upturned 

 Silurians in the neighbourhood of Jedburgh itself. There is 

 even a finer section than that at Allars Mill, to be seen in Wood- 

 field Burn and Willowford Burn — two little streams which unite 

 just before they enter the Jed a little below Mossburnford. 

 The best section is in the Woodfield Burn — one of the clearest I 

 ever saw anywhere. Close to Dovesford (Oamptown) the Lower 

 Silurian comes out from under the Old Eed Sandstone and forms 

 the bed of the Kaim burn up to Edgerston House, where conglo- 

 merates and grits overlie sometimes the Silurian, sometimes the 

 Old Eed igneous rock (Porphyrites). Dod Hill (977 ft.) is a cap 

 of coarse red sandstone resting partly on Silurian and partly on 

 Porphyrite, which last forms Stotfield HiR (967 ft.), and the 

 other hills overlooking Edgerston House on the east. This 

 mass of Porphyrite is an outlier nearly entirely surrounded by
