Capitolo 58
this age that it almost overcomes belief; and still their are the
results of accurate deductions. The first presence of this ice
same sheet has shown in a more conclusive way from the bowlder
clay formed under the great glacier, while containing abundant
examples of stone that it shows from their surface scratched that them
you/he/she has been ground long under the glacier. The stones on the
sides of the mountains are precisely scratched as it is those in the
Alps. Observing as tall on on the mountains the striaes are,
we know the bigness of the ice-sheet; and the direction in
what stirred you/he/she has shown in many ways.<22>
The geologist assures then us, shortly, that when the cold of
the Glacial age was to its streamed of glaciers of maximum down from
all the mountains of Scotland, Wales and Northern England;
what the ice was often enough to overtop all the smallest hills,
and on the plans it united in a great sea of ice some
thousand of feet in bigness that has extended as far south
as the latitude in London, England. But what to the west the ice
streamed out through, the Irish Sea, the islands to the west of
Scotland, and it ended out far in that what time the Atlantic is.<23>
But these glaciers, enormous as them they were, it was very small comparative
with the glaciers that the streamed out of the mountains of Norway
and Sweden. These great glaciers invaded England to the south-
west, rejects the ice of glacier of Scotland from the floor of
the Sea of the North, Denmark overflowed, and spread their mantle of
clay of bowlder distant south in Germany.<24>
While such it was the condition of things to the north, the
glaciers of the Alps were a lot of times greater than currently.
All the valleys were filled with ice of glacier, and they scattered
far out on the plans of Southern Germany and toward west in
France. The mountains of Southern France and the Pyrenees also
sustained their system separate of glaciers. I also freeze descents
mountains give of Smaller Asia and north Africa.<25>
In America we meet there with traces of glaciers on an enormous staircase;
