The abundance of superglacial drift on this small ice-sheet in 
Alaska, and its comparative scantiness on the greater pai-t of the 
border of the extensive ice-sheet in Greenland, seem readily ex- 
plained by the recent and present rapid decrease of the Alaskan 
ice, while that of rireenland is probably now increasing and the 
climate growing somewhat colder, t 
Both these ice-sheets lie on or near Aery mountainous districts. 
It will be of the highest interest to glacialists to obtain similar ob- 
servations of the Antarctic ice-sheet, for most portions of its vast 
expanse seem to flow out into the sea from areas of low, land, 
more nearly representing the basin of the North Sea. from which, 
according to Lamplugh, the confluent Scandinavian and Scottish 
ice moved upward over the eastern shores of England, bringing 
much englacial drift derived from that lower area. In like situa- 
tions, too, far from mountainous or even notably hilly country, 
are the localities Avhich have aflorded to me the greatest estimated 
thickness of the englacial drift, as about forty feet adjacent to 
the Altamont moraine on the Coteau des Prairies in southwestern 
Minnesota, t and about the same amount where currents of the ice- 
sheet converged from the northeast and northwest at Birds Hill 
near Winnipeg, Manitoba.^ In each of these places the englacial 
drift is largeh' derived from the neighboring low region.
