No serious study of archaeology in this continent can overlook the importance or interest of the inland mounds which dot this country. Here in an explicit text, the author discusses the function of these mounds within prehistoric society. He describes evidence found therein--skeletons, artifacts and art--and reconstructs the civilization of the ancient tribes to whom the mounds played such a vital role. Illustrated in black and white, this text by the author of The Cave Hunters affords the young reader a very exciting perspective on historical time and provides him with a certain humility in regard to the achievement of ""modern man"".
