Capitolo 59
but we cannot make a break describe here them.<26>
It doesn't have need to catch us, therefore to know about reindeer and
the food of musk-sheep on shabby herbage in that what time it constitutes
Southern France. When a continuous mantle of snow and ice
covered with a mantle Northern Europe, it is not to entirely surprising to find
the evidence of an extremely cold climate that prevails in his
you confine southern. We see as a piece of the adaptations of evidence
in another, and therefore we am able, with some trust,
strive to find tests of the most genial conditions when the snow
and ice disappeared, and a more luxuriant vegetation possessed
the earth, and animals got used to heat and also tropical
countries erred on a great extension of European territory.
In Switzerland it was suitable a long time ago that after the
ancient glaciers had occupied for a lot of time the low motives of
that country that them, for of the cause they have stepped backwards to the mountain
valleys, and it allowed brooks and rivers to work on the
debris < / the > it went away behind them. To more interesting Wetzikon
conclusions are been drawn. We learn there that, after the
withdraw some glaciers, a lake it occupied the place that in
course of time was filled accordingly with peat and that
the peat was turned into lignite. To judge from the rests
of animals and plants, the climate is due to be at least as
you currently heat as that; and this condition of things has to have
prevailed on one period of of the thousand of years to explain
the thick deposits of peat from what it originated the
lignites.<27>
But we also know that this period ended, and that once
the ice came down anymore. This has shown from the fact that directly
overlying the beds of lignite are alternating layers of sand and
you gravel, and, remaining on these glacier-been born bowlders. The same
conclusion follows from the discoveries sorts to many
other places.
In Scotland it is known well that the clay of bowlder contains
rolls sometimes sprinkled of peat and beds of ground
one deposited in lakes or rivers. The only explanation that
