Capitolo 54
you strengthen this sight from an appeal to the vegetation of
this period.
We have seen how important a guide as to climate it was the
rests of the vegetation of the first times. We turn therefore
with more trust to such discoveries as it will tell us of the
flora of this age. But there are a lot of reasons because he/she remains of
the growth of plant should be little. As we will learn soon, this was a
period of flooded rivers; and in the gravels and it dresses again of clay this way
format is found our principal source of information as to the
the life of the age. But such rush of waters would form ghiaiato
banks or the great clay beds, and it would sweep some plants that
you/he/she would have washed out far in his/her floods to sea; or if by chance
they should be buried in such beds of gravel, the action of
water would quickly provoke the decadence of the tender portions,
how leaves, barking and soft wood in that the case anybody profitable
investigation could be made. However, every now and then around the
beaches of old lakes, read vegetable I/you/they have been buried, and us
knows that some mineral springs deposit a kind to protect
I on every thing with which they comes into contact. From this way
he/she wants to say, to rare intervals, leaves, seeds, and fruits they have been,
sealed above for future inspection, and from an accurate study of everybody
man quotes an example a lot of precious information is been gotten.
To that place in the valley of the Seine it was open under a,
bed of tufa, the rests of a growth of forest. You/he/she is not doubted
what the deposit belongs to the Glacial age.<17>
He/she anchors the growth of forest he/she remembers to that common during the
Miocene Age. The fig tree-tree, canary crowns of laurel, and box-tree grew in
profusion. These are all the southern forms. A severe winter is able
kill them all, and also hard colds would prevent the mature ones
of their fruits.
Neither it was the summers warm and dry. This has shown from the
presence of numerous plants that you/they cannot flourish in heat and dry land
