The border between Canada and America was shaped by heroism and conquest, Forged by the meanest personal ends as well as unselfish sacrifice, and sustained by the vision and statecraft of a handful of great men. The border, as Mr. Hutchinson also convincingly demonstrates, has become an osmotic wall rather than a barrier, eliminating conflicting personal and national values, and admitting what each country lacks in human and industrial resources. A Canadian, neither a historian nor a sentimentalist, he has traced the adventure-laden record of this remarkable union. If his material at time breathes fire and violence, his manner is restrained but doggedly patriotic. Champlain, La Salle, Frontenac, Alexander, Mackenzie, Mackenzie King, Washington, Jefferson, Franklin, Lewis and Clark, Buchanan- these are among the illustrious here. With this numberless band the author crawls and battles his way across a continent; destroys settlers and Indians and plants the grain wealth of a new people; connives; wheedles and outbargains among the parliaments and trading-posts of the world until he has won freedom for Canada, a new concept of sovereignty and international goodwill for the U.S., and indestructible harmony for the whole of North America. The Incredible Canadian, The Unknown Country and now this, rank Mr. Hutchinson with Bernard de Voto and promise him a welcome from the same enthusiasts of uneviscerated history.
