Capitolo 88
you are waited that they happens in the valley of river, and this is the case,
although in some examples have been so immense changes in
the level of surface of the country that we cannot now find trace
of rivers near their. This is exactly similar to some gravel
you deposit that, as we have seen, you/he/she is found every now and then where
now it is not water in march. However, the most famous caverns are
you find tall on on the banks of existing rivers. We cannot doubt
what the rivers were the cause of the caverns. But having
dug then their beds under the level of the existing caverns,
they stopped flowing in them, and he/she left them to be busy from
wild animals and the men as soon as less savage. But to durations,
inflated by floods, the river would affirm again its supremacy
and it rolls his/her waters through his/her old channels.
These floods would not only break and they would rearrange anything
debris < / the > you/he/she had already accumulated, but he/she would introduce
quantity of sediment and rests of animal. In such some way
as it is suitable here (although precisely as geologists are not
state of accord) caverns were invaded, after being busy from very from men or
animals, from floods of water. In many cases evidence is able
you seem to point out that after such water visit the cavern
and his/her water-rolled contents and it water-systematized you/they had gone away
makes to keep silent, neither it visited from crews neither beast. In such examples
coverages of stalagmitic would gradually form on the confused ones
debris, and in of the places acquires a lot a bigness of
feet. In of the examples very this way floors are found above one
the other, sharpening to one period prolonged of use and then a
calm stage where it broke alone the dripping of water that falls the
makes to keep silent, and nature sealed on another chapter of the biography of cavern
under of the layer of stalagmite.
One of the most important caverns in England are the Cavern in Kent,
before it mentioned. This cavern was attentively explored under the
