The vegetation will follow the human emigration.

The flora will retreat towards the Equator at the same time as the fauna.

The central parts of South America and Africa will be the continents chiefly inhabited.

The Laplanders and the Samoides will find the climate of the polar regions on the shores of the Mediterranean.

Who can say, that at this period, the equatorial regions will not be too small, to contain and nourish terrestrial humanity?
Now, may not provident nature, so as to give refuge to all the vegetable and animal emigration, be at present laying the foundation of a new continent under the Equator, and may she not have entrusted these insects with the construction of it?
I have often thought of all these things, my friends, and I seriously believe that the aspect of our globe will some day be completely changed; that by the raising of new continents the sea will cover the old, and that, in future ages, a Columbus will go to discover the islands of Chimborazo, of the Himalayas, or of Mont Blanc, remains of a submerged America, Asia, and Europe.
