Illustrated. Marshall B. Gardner, a hollow-earth proponent, attempts to come up with a scientific hypothesis to explain the formation of hollow planets. A very readable book. One of the most enjoyable parts of which is Gardner's fantasy account of a journey into the interior of the hollow earth, which, while not up to the standards of Jules Verne, seems almost plausible.
