Cities in the Sea

by Nicholas C. Flemming. Doubleday, $10.00. Mr. Flemming, a marine archaeologist, bundles together sunken-city legends (for which he has a practical, if cautious, respect), Atlantean mythmongers (for whom he has no respect at all), actual underwater explorations and discoveries, and beguiling descriptions of Mediterranean scenery. The mixture should delight any reader interested in this new and still romantic form of rummaging in the tribal attic. Maps, photographs, bibliography, and a short course in submarine geology and equipment.
