The Late Glacial in North-West Europe: Human Adaptation and Environmental Change at the End of the Pleistocene

quoian group too as a set of polities, not a single one. It also provides fascinating detail on longhouse construction. There are no references in Iroquoian chapters to the ideas of United States scholars who, based in part on New York Iroquois data, debate the timing and magnitude of the depopulation that attended European invasion. Moreover, invasion-period data are accommodated to the historical record rather than serving as an independent means of complementing it. Fox offers a useful summary of Odawa prehistory, although the time depth of coverage is unclear. What is clear from the chapter's limited scope and reliance on ethnohistoric as much as archaeological data is that later Algonquian prehistory is the poor relation of Ontario archaeology. This is unfortunate, because we have few ethnographic analogues for forager cultures in temperate habitats, a fact which alone justifies close study of the Odawa. Heidenreich's chapter on the history of Iroquoian groups is just that—history—and so perhaps out of place in a book explicitly confined to prehistory. ASO concludes with comments by Wright. Chronometrics are an obvious concern in ASO. Unfortunately, Klein's 1982 calibration is used, not the 1986 models already available when ASO was written. There exists a good deal of unhappiness with the accuracy and precision of late prehistoric C dates, for which Iroquoianists might be partly at fault especially if, as Wright suggests, they prefer perennial to annual charcoal. Closer attention to probabilistic C interpretation and sample selection is advised in order to improve results. Absolute-seriation approaches based on time-dependent metric variation are applied to European trade goods but not to aboriginal artifacts, though contributors document such variation in classes like fluted and late prehistoric bifaces, Younge and Vase ceramics, and longhouses. Contributors exemplify familiar trends in North American archaeology; they include more archaeologists in provincial and private practice than in academics. The fast pace of contract research in Ontario also is reflected in the text and ASO is admirably prompt; most contributions were completed in 1988 and 1989. It is surprising, however, that almost all contributors are men. ASO bears few typographic errors and is amply supplied with artifact and site-plan illustrations. An inserted erratum sheet lists six errors scattered over 500 text pages, and few others are evident. ASO lacks a master chart of time-space systematics as well as a concluding chapter that might have provided both summary and suggestions for future research. The bibliography is superb. Lack of an index is frustrating but understandable in a noncommercial publisher, which is, notably, a chapter of the provincial society. It is hackneyed but true anyway to say that eastern North American archaeologists who ignore this book do so at their own risk. As a model for prehistoric synthesis of a major region, and as a reference source for data and current interpretations of prehistory, ASO has few equals.
