That European flora invaded us, I presume, immediately after the glacial
epoch, at a time when France and England were united, and the German
Ocean a mere network of rivers, which emptied into the deep sea between
Scotland and Scandinavia
That European flora invaded us, I presume, immediately after the glacial
epoch, at a time when France and England were united, and the German
Ocean a mere network of rivers, which emptied into the deep sea between
Scotland and Scandinavia. And here I must add, that endless questions of
interest will arise to those who will study, not merely the invasion of
that truly European flora, but the invasion of reptiles, insects, and
birds, especially birds of passage, which must have followed it as soon
as the land was sufficiently covered with vegetation to support life.
Whole volumes remain to be written on this subject. I trust that some of
your younger members may live to write one of them. The way to begin
will be: to compare the flora and fauna of this part of England very
carefully with that of the southern and eastern counties; and then to
compare them again with the fauna and flora of France, Belgium, and
Holland.
