Book excerpt: Lass's book will be the standard work on the Lake Superior to Red River boundary, but it reaches beyond those limits defined in the title. In order to make any sense out of the border, Lass has gone a long way towards writing a good general survey of Canadian-American boundary issues. The book is based on an extensive use of published and manuscript materials, and it is well illustrated with photographs and maps, including reproductions of important historic maps."--Www.mhs.ca/docs/mb_history/04/boundarycommission.shtml.
