To most people interested in seismic prospecting, the title of the volume will perhaps be somewhat misleading. A large part of the book is devoted to earthquake lore in general; and those early chapters devoted to the geology of this subject, the reviewer found intensely interesting. On the other hand, the treatment on seismic prospecting, as the term is generally understood, is rather inadequate. One feels that the author might have done far more with the various theoretical considerations of instrumental technique, elastic theory, wave-propagation and such. The treatment, mathematical and physical, cannot be considered convincing—in fact this writer feels that it is definitely superficial in most places.
