Early Man and the Ocean

by Thor Heyerdahl.Doubleday, $12.95. These papers, written on the whole for a professional audience but by no means too technical for the general reader, have been assembled to clarify Mr. Heyerdahl’s position on the diffusion of cultures and peoples by early seafarers. He is less romantic and less dogmatic than his more exuberant followers, and much more careful to distinguish possibility from probability and both of these from solid archaeological evidence. Illustrations, notes, bibliography.
