stones, its irregular bedding and the nature of its longitudinal 

 variations may be classed as a glacieluvial kanie. Its chief curves 

 are coiicave to the W. ; that fact and the frequency of former pools 

 between it and the drumlins to the P]. indicate its formation along 

 the E. margin of ice which flowed from the W. and abutted against 

 the drumlins along the coast. According to Lebour (op. cit., p. 21) 

 this kame consists of '" marine deposits ". 



Buckland ^ has referred to the southern end of this kame at 

 North Charlton as a tortuous bank of gravel and as supposed to be 

 " an inexplicable work of art ". 



4. S. N orlhumherland . — H. Miller has remarked - the morainic 

 character of some kames near Elsdon and Harbottle in the valley 

 of the Coquet; they appear to consist of glacieluvial material. 

 Widespread fiuvioglacial sands and gravels occur in S.E. 

 Northumberland ; some of them, as at Eachwich and Dissington 

 beside the Pont R., E. of Stamfordham, and those of the Newbiggin 

 and Blanch Burns, appear from the description of Dr. J. A. Smythe ^ 

 to form original kames ; others form residual kames. Professor 

 Marr has reminded me of the ridged form of those near Corbridge.' 



IT. Durham. 



Similar in origin to the Lucker Kame a])pear to be the kaiiies 

 near the coast of Durham, including a circular mound of gravel at 

 Betterlaw and a group of deposits at Sheraton, 5 miles W. by N. 

 from Hartle])ool. These deposits have been described by 

 Dr. Trechmann ^ and by Dr. AVoolacott.*' The latter author gives 

 full references to the literature. He concludes that they are marginal 

 deposits along the W. margin of the Cheviot glacier, and are true 

 kames. Trechmann has found in one of them a Scandinavian 

 boulder — possibly derived from the North Sea boidder clay. 



A kame has been identified at Durham by Carvill Lewis.' It 

 lias been re-examined by Dr. Trechmann and Dr. Woolacott, and 

 the former says " that in their opinion its form is due to post-glacial 

 fluvial erosion. 



The formations described by Dwerryhouse " as esker-like ridges 

 in the valleys of W. Durham, especially near Stainmoor and Lunedale 

 and in the valley of the Tees above Barnard Castle, probably also 

 owe their form to post-glacial denudation.
