How man has harnessed water power all over the world

Centuries have passed and much water has flowed over dams from the time when primitive man first thought of controlling a stream to the present era of giant dams. The story of how man has harnessed water power and used it to make a better life for himself is an exciting one that is basic to our civilization. The role of water power in building up industry in the United States, the part played by great dams in conservation and wildlife, the problems of siltation, the choice between private and public control of power—these are some of the many questions discussed in this book.

In telling this story, Dorothy Hogner takes us all over the world. We not only learn of the ancient dams in Europe and elsewhere, but of the great engineering projects of modern Egypt, Russia, Australia and this country. Here is a fascinating picture of what man has accomplished and what he plans for the future.
