and reindeer, lived around the whole year in Southern France.
The woolly mammoth lived in Spain and Italy. In short, the
climate and the conditions of the life were vastly different in the
two stages.
We now have to turn our attention to the tests of glaciers in
Europe, the phenomenons from which this age deduces its name.
Descriptions of Alpine glaciers enough they are common, but as
glaciers and the Glacial age have a great quantity to do with the
the antiquity of man, we cannot do best that to learn what we am able
of their formation and their marvelous delay during this
period. The school-boy knows that from pressure he gives his
you almost increase whirlingly the hardness of ice. He could manufacture I really freeze him
if he possessed enough strength. The fact is, then, that
it snows under the influence of passages of pressure in the form of
ice. In of the nature of cases this ago on a great staircase.
Where mountains are sufficiently elevated to raise their heads
above of the line of snow we know that they is white the whole year around
with snow. What doesn't is not fly away, evaporated, or, as a
crushes by an avalanche, it fell to lower heights, it has to accumulate from
per annum to year. But the weight that presses on the lowest portions of
this I snow-live it has to be considerable soon, and for a long time it becomes
so great, that snow changes to the form of ice. But as I freeze
it is not sheltered anymore and immovable. We don't have need to stop to explain
only as this I ice-live it stirs, but the fact is that, nevertheless
very slowly moving himself/herself/itself, it behaves as a liquid body. It will steal
street on some inclination however small down that it is able water
flow. As a river fills the valleys that conduct down from the
mountains. But, lowers down clearly him, him I flow the tallest
the temperature that satisfies, and a will arrive sooner or later
point where it will melt as fast as it advances. This brook of
I freeze that flows down from mountains snow-dressed has called a glacier.
Those with that we am better informed I am but the small things compared
