Since the time of Columbus, when the peoples of the New World were discovered by Europeans, there has been a continuous interest in knowing something about their origin and early history. This has been almost completely shrouded in the primitive past, unmentioned in any written records, and thus largely a matter of speculation of one kind or another. Only very slowly have the means of investigating this history come into being. Greater knowledge of all the world’s peoples has provided the means for solidly based comparative studies, and the developing techniques of archaeology have brought more factual evidence to hand. Gradually the true picture is taking shape as each new discovery is analyzed and discussed and takes its place in the total structure. This is an exciting adventure in discovery and learning that many would like to share more completely with the archaeologist and anthropologist. Usually, however, the reports of the professionals are too technical to be meaningfully understood by the layman, and the brief accounts of “finds” and “digs” that appear in the press are far too fragmentary. Most fortunately, we have the present book, which fills the need very nicely—far better than anything else in print. Kenneth Macgowan professes to be an amateur in archaeological matters and, technically speaking, he is, although his competence in the extraordinarily involved subject he deals with is certainly of professional stature. In any event, he clearly discerns what is needed by the amateur and, without minimizing the complexities and involved problems of his subject, he provides the background to make them understandable. To incorporate the various discoveries and new formulations that have appeared in the twelve years since this book was first published, the text has been revised and brought up to date, largely by Professor Joseph A. Hester, Jr. This has been skillfully done in a way that does not alter the quality or coverage of the original. I have been recommending this book for many years and now begin a new series of such recommendations. I am sure that it will be enjoyed and found most illuminating by all who want to know how the early history of man in the New World is being revealed. GORDON F.
