Secrets of Earth and Sea

We possess, a vast heritage of knowledge handed on to us in tradition and in writings from our father-man in the past. But there are yet immense fields of knowledge to be explored and yet a greater task to be accomplished in spreading the knowledge which we possess, and in persuading all men that it is their right and their duty to acquire it and to enjoy the power and the pleasure which it gives. All must also help, directly or indirectly, in the making of new knowledge. Whilst mankind is still so backward in knowledge and the worship of wisdom, it is idle to indulge in despair of the future. A chief way to increased welfare is still open and untrodden.
These are big speculations and problems with which to preface a small book. But I am content to offer the small book as a contribution, however restricted, to the spread of a desire for further knowledge of the things about which it tellsa possible incitement to serious study of some one or other among them.
