The echoes of Laurier's remarks about Canada and the twentieth century are taking a long time to fade away. It is one of the purposes of Professor Johnson's Alan B. Plaunt Lectures (given at Carleton University in 1962) to silence them, for they can prove dangerous and misleading-like a siren song-in the formulation of Canadian economic policy at this time. The success of the Common Market, Britain's request for membership. President Kennedy's desire for tariff flexibility and reductions in the United States, and the recent stagnation in the North American economy (accentuated in Canada by an emphasis on monetary stability)-these are signs of change in the economic climate of the world. The requisite adaptations are the most important problem facing those who govern the economic life of this country, and they must be faced realistically to ensure Canada's continuing economic growth. Professor Johnson analyses his subject with his customary authoritative skill and lucidity. Written in non-technical language, this book presents an ideal summary of the contemporary economic world as it affects Canada.
