448 THE GLICIATION OF THE BLACK COMBE DISTRICT. [Sept. I912. 



EXPLANATION OF PLATES XLI-XLIII. 



Plate XLI. 



Fig. 1. The Kinmoiit-Beck Valley, east of Low Kinmont, looking eastwards. 

 The pre-Glaeial granite valley was filled with Boulder Clay, which 

 is now being removed and re-arranged as terraces by the stream. 

 (See p. 422.) 

 2. The Kinmont dry valley south of Welcome Nook, looking southwards. 

 This view shows a broad marshy floor and a steep wall on the outer 

 side of the bend. (See p. 425.) 



Plate XLII. 



Fig. 1. The Corney-Hall dry valley, looking eastwards. The view is from the 

 bottom, looking up towards Corney Hall at the eastern end. In the 

 background the Corney valley crosses at right angles. (See p. 426.) 

 2. The Near-Bank ' in-and-out ' valley, looking northwards. Near Bank 

 is the farm on the right of the observer : the granite-crag on the left 

 is isolated. A small stream enters upon the right, and throws a delta 

 across the valley. (See p. 426.)

Discussion. 



Mr. G. Bakroav remarked that the Author was dealing with an 

 incident in a great campaign. England had been invaded on both 

 sides by ice-sheets — one from the east, the other from the west, 

 which had left traces of their course in the form of dry valleys cut 

 by streams flowing at the margin of the ice. The Author had 

 described the phenomena produced along successive margins of the 

 western sheet, in the south-Avestern portion of the Lake District ; 

 the speaker had noted a great gorge (Rudyard Gorge) cut by a 

 marginal stream at the southern end of the Pennine Kange. What 

 was now wanted was a description of the valleys and ledges left 

 by the ice in the great intervening area, on the western side of the 

 Pennines. 



Mr. G. W. Lamplugh said that, having some time ago traversed 

 part of the area described, he could corroborate the Author's account 

 of the general conditions of its glaciation. The movements of 

 existing glaciers had proved to be so irregular, that it was un- 

 necessary to expect much regularity of arrangement in the marginal 

 channels. 



The Atjthok, in replying, thanked the President and Eellows 

 fur their kindly reception of his paper.
