I think it takes a gifted writer to be able to make the subject of earthquakes interesting to a complete novice for as many pages as this. And it was interesting, even in the face of the author's desire to substitute fact for fiction (he made fact as interesting as fiction). He shows how earthquakes and the science of seismography have contributed to architecture, to geology, to the petroleum industry. He traces the historic background of the Jesuit interest in the subject. He gives a whole chapter to a meticulous description of the vault at Fordham where the observations are made. And he ends with a chapter for amateurs.
