Heinrich Schütz
When Mammoths Roamed the Frozen Earth
1928 (1929)
from the dustjacket:

Rarely has a publisher the opportunity to offer a book that is exciting and informative to young people and at the same time fascinating to adults. This book, the title of which literally translated is "The Dying Glacier," is one of the most remarkable works of its kind to appear recently in Germany. In that country it has had great success both as literature and as a thrilling account of nature and the strange forms of life in that weird period of the earth's history when man was beginning to emerge as a conqueror.

Nature, — the gigantic glaciers, the luxuriant and overpowering vegetation where the icy wastes left off, is the chief protagonist in this book. There are storms and savage landscapes more awe-inspiring than any we know, and in the midst of cataclysms, when the earth was releasing itself from the pall of ice which had held so vast a space rigid for many centuries, there emerges the intense drama of life. Here are battles between hordes of monstrous creatures which the reader will find it difficult to forget.

As literature the book is what German critics have called it — "magnificent" — and the author's gift for imaginative narration, founded on accurate scientific data, has rarely been surpassed. In addition to the enthralling subject matter of the book its exciting illustrations will captivate any boy or adult.
