On the eastern side of the Atlantic, Wales, Cumberland, 
many parts of Ireland, the North Highlands, and some of the 
Western Isles are also dotted with unnumbered lakes and tarns, 
All of these are well-glaciated countries, both high and low; 
and for Wales and many parts o otlan , [can answer that 
by far the greater = of these lakes lie in rock-basins of 
2 glacial origi 
cases of glacier-erosion, though in the case of the former it may 
be that the alluvial deposits on the banks of the Leven prevent

ee the lowlands of Scotland numerous examples of the same 
kind of rock-basins occur, some of them certain, others doubtful 
ause of the surrounding drift, which inde ed in some cases 
may be the sole cause of the retention of the water. Notable 
examples of both kinds occur in the lowlands of Fife and Kin- 
, and of true rock-basins in the Cleish and Ochil Hills, as 
for instance Loch Glo ow, Dow — and the two Black Lochs, 
and more doubtfully Loch Lind

Vian peninsula, which, geologists are aware, is through all its 
length and breadth, one “of the most wonderfully glaciated coun- 
tries in the world. On the west, descending from the great 
chain, striated roches moutonnées plunge right under the deep 
fiords; and on the east, in Sweden, all between the mountains 
and the Baltic, round the Gulfs of Bothnia and Finland, and up 
to the North Sea, the whole country is covered with a prodigious
