True adventure, keyed to the level of Junior High School interest in various aspects of modern scientific adventure. The material was thoroughly tested out, both for subject matter and handling, by pupils in California, Arkansas, Illinois and Michigan, and the results show careful organization and a good sense of dramatic story telling. Among the modern heroes and exploits are told the stories of Beebe and the ocean depths, Everest and the Norton expedition, the Redfern mystery, Lindbergh, Livingstone seeking a trade route for white ivory in the heart of Africa, Scott, hero of the South Pole, and others, fourteen in all. There is one unfortunate omission -- there is no bibliography. I'd suggest to librarians that there is opportunity here to link this book with the source material of the records of the individuals and their experiences.
