Memoirs of a Speleologist consists of sixty-six short and lively sketches
running the gamut from comedy to tragedy and near-tragedy. The reader
encounters cowards and heroes, experiences the deep thrill of rediscovering
a cave where man had dwelt thousands of years before, and feels the pathos
and joy of de Joly's last cave visit at the age of eighty. Above all, the book
displays the dominating personality and eccentricity for which de Joly was
known, and conveys a strong impression of the landscape, people, and
caves of the causses, the cave-riddled limestone region of southern France.
