LAST STAGE OF ICE AGE IN SCANDINAVIA 327 
of the Scottish Highlands. The explanation is the same in 
Norway as in Scotland; they are the beaches of lakes which 
were dammed in by ice during the late glacial time. Dr. Hansen 
has tried to give an elaborate account of the manner in which 
this came about. He thinks that the ice melted latest where 
the thickness was greatest, and that the last remnants came to 
d 
lie as a narrow strip of ice, a sort of “‘ice sausage,” on the slope 
of the south of the divide and somewhat parallel to it (see 
Fig. 1). On the diagram the shaded part shows the ice in the 
last stage, and the lakes were dammed in between it and the 
divide. The readers of this JouRNAL may remember that this

explanation was hinted at in a paper by Dr. Hansen, entitled 
“Glacial Succession in Norway,” Vol. IH, 1894, p. 137, conclu- 
sions, by the way, to which most Norwegian geologists assent 
only to a limited extent. 
By his explanation Dr. Hansen has made urgent the question 
at what place the last remnants of the inland ice were located. 
Mr. Schiétz, professor of physics at the University of Christiania, 
has criticised Mr. Hansen’s views from the physical standpoint 
in a paper entitled ‘‘How will the ice divide act during the 
melting of the inland ice?” printed (in Norwegian) in Myt 
Magazin for Naturvidenskaberne, Vol. 34, Chr., 1895, pp. 102-111. 
He demonstrates that any “‘ice sausage”’ on the slope below the 
divide can come into existence only in the case that the melting 
takes place so suddenly and quickly that the snow line during 
the period of melting is at a greater height than the crest of 
the country. If the snow line rises gradually as the tempera- 
ture rises, the diminishing glaciers will concentrate at the divide. 
He thinks this the most probable case, and points to the great 
local glaciers which undoubtedly have descended from the
