MORE than a hundred contributors, all from the America have undertaken the task of producing the volumes of this Handbook, of which the two under review are the first to appear; a volunic will be devoted to each of four cultural divisions into which South America and certain regions to the north have been divided: marginal and hunting tribes from Terra del Fuego up to northeastern Brazil; the Andean civilizations to the west; the tribes of tropical forests and savannah in the great central areas of the sub-continent and on the east coast; and the circum-Caribbean cultures to the north and up the Isthmus to Honduras and along the Antilles to Cuba. The fifth volume, designated the comparative anthropology of the South American Indians, will contain general summaries and comparisons of the various aspects of the cultures previously detailed. An arbitrary outline, arranged to a standard sequence, has been followed by the contributors of each article, to assure proportionate brevity and facility of reference.
