At p. 246 it is mentioned that “the upper parts of the hills 
between Fundingsfiord and Andafiord were above the limits of gla- 
ciation.” . . . “ Suderoe has supported a considerable mass of ice ; 
for we traced the glaciated outline up to a height of 1040 feet. 
Above that level all is rough, angular, and serrated ” (p. 248). 
The explanation suggested by Dr Geikie of these interesting facts 
is, that “ when the islands were enveloped in their ice-sheet, the 
action of frost would he confined to such ridges and hill tops as pro- 
jected above the mer de glace, while severe glacial abrasion would 
go on below ” (p. 260). 
Dr Geikie, in his Memoir, more than once takes notice of the 
“ scarcity of moraine mounds, which, he says, “ it is difficult to 
account for satisfactorily ; ” — but he offers under that head several 
suggestions, “ the principal ” being,' “ probably the continuous and 
comparatively rapid dissolution of the ice, after the snow-line had 
retreated several hundred feet above the sea-level ” (p. 263).
