England. I pointed out to him that the structure of the mounds, 

 they being so kirgely composed of stratified material of fine texture, 

 differed from any j^ortion of the Great Terminal Moraine of Ame- 

 rica known to me ; but he insisted that the position, outline, and 

 mode of arrangement of the mounds were of prime importance, and 

 that their composition was a secondary matter, depending on the 

 shape and character of the terminal slope of the glacier and of the 

 receiving surface, and the distance of the material from its original 

 source ; and added that similar local modifi.cations were by no means 

 unusual in the States *. 



I shall have occasion to revert to these views of Prof. Carvill 

 Lewis in a later portion of my paper. 



lY. Description of the Sections. 



In attempting to describe over fifteen miles of ever-changing 

 sections, it will of course be possible to record only a small portion 

 of the details of the beds ; but in some cases fuller descriptions 

 have already been published in my former papers t, in the publica- 

 tions of the Geological Survey i, and in other works which are 

 mentioned in the footnotes. Under such circumstances it must be 

 remembered that some of the facts brought into prominence might 



* These views were incorporated by Prof. Carvill Lewis in his papers read 

 at the British-Association Meeting of 1887 ; see also Warren Upham, in Geol. 

 Mag. (1889) p. 157 ; but as only short abstracts of these papers were published, 

 I think no excuse is needed for now dwelling upon these valuable expressions 

 of opinion.
