WHEN THE WORLD WAS
By
An outline of the story of the earth, its origin, geographical evolution and the course of development of the life it has supported, lucidly and simply presented for any age. The formation of the earth and its surfaces, the explanation of natural forces, through the various stages of animal and plant life, from the vanished dinosaurs to the inhabitants we see now. A book for students of any age, but one which predicates an initial interest in the subject.
