the glaciers would appear to have come down the valley from the 
west rather than wholly from the valleys of the Derwent and Dove. 
There is no evidence to show that there might not have been several 
glaciers in Newer Pennine times. On this point I remarked, 
six years ago, “I have only been able to show the existence of one 
period of glaciation during this epoch, but there might have been 
two or even more, separated by considerable intervals of time.” 
According to Professor Geikie there were three—his fifth, seventh, 
and ninth epochs. In these Later Pleistocene times the direction 
of the ice-flow was, as the surface disturbances show, again in 
accordance with the present local features of the country, the 
direction of the ice-flow which formed the Great Chalky Boulder- 
clay having been quite an abnormal one.

HE new school of glacial geology has found a champion in Mr. 
Percy Kendall, who, in ten pages of this MaGazine (November, 
1892, pp. 491-500), attempts a reply to some of my criticisms.? 
Since then Dr. G. F. Wright’s work, entitled “‘Man and the Glacial 
Period,” has made its appearance, and in this Mr. Kendall is allowed 
44 pages to explain his views of the glacial phenomena of the 
British Isles. 
Mr. Kendall asks for ‘“‘a clear exposition” of my views under 
no less than seven heads, at the same time stating that it would take 
two years’ issue of this Macazine, with no end of double numbers,
