solid ice. By this lifting process, pockets of loose clayey sand were 
thrown on top of the morainic matter, producing thus the appear- 
ance of having been ploughed up 
by the glacier to even several 
yards beyond its termination, 
which has not been the case. 
Nowhere is there apparently 
more ploughing action, and yet 
little or none to be seen, than at 
Buarbree,which is advancing rap- 
idly against a high lateral mo- a 
raine. There is a large ridge gM-

ice were pushing under the boulders of earth. The glacier has a steep 
convex margin, from twenty to forty feet high, with many blocks 
and boulders upon it. These become detached, and, rolling down 
upon the lower tongues of ice, build up a ridge and leave a deep 
trough between it and the side of the glacier, and delay the melt- 
ing of the layer of ice beneath, which is too thin to do any plough- 
ing up of the moraine.

the early summer retreat of the glacier, although again advancing 
in July. The lower surfaces of the ice-tongue were furrowed by 
the loose stones of the soft incoherent water-soaked moraine, into 
Which one’s foot would sink when stepping upon it. The moraine 
was being levelled by the constant dripping of the water from the 
whole under-surface of the advancing glacier. 
The glacier of Suphelle is the most remarkable of its kind, being 
a gigantic glacier rémanié. From the Jostedalsfond, which, near
