Louis Agassiz Quote

The long summer was over. For ages a tropical climate had prevailed over a great part of the earth, and animals whose home is now beneath the Equator roamed over the world from the far South to the very borders of the Arctics.... But their reign was over. A sudden intense winter, that was also to last for ages, fell upon our globe.
