There is no evidence provided in the essay to suggest that profit maximization and standard economic reasoning could not provide a reasonable explanation of seasonal rounds. In his analysis of the role of shipping in early nineteenth-century Scottish emigration to the Canadas, Cameron recognizes that a theory of migration ought to deal comprehensively with both "push" and "pull" factors, yet no theory is specified to facilitate a test of his hypothesis about the availability of transportation. The essay really ends where it begins with the assertion that the role of transportation is self-evident. Although many of the essays may be criticized from a social-science history point of view, the volume will surely serve a useful purpose if the articulation of new data sources and unresolved questions stimulates future innovative research in Canadian rural history.
