Sometime in the future, I hope that there will be published an exhaustive account of one of the most revealing episodes in the recent history of our two countries. I refer to the propaganda for and against the proposed development of a great navigation and power project on the International Rapids Section of the St. Lawrence River.

Doubtless other political movements in our history have a public significance even greater than that of the St. Lawrence seaway. But the St. Lawrence project probably offers to historians, to political scientists, and to economists, a more illuminating study of the way in which our democracies act, or fail to act, under the drives of conflicting pressure groups and of conflicting social philosophies than does any other political controversy of recent years. This is true because the underlying motives of the people who have taken part in the fight for this project are more clear-cut and less camouflaged than those involved, say, in controversies about the protective tariff, or about the merits of American isolationism versus interventionism in international affairs. So broad is the significance of this case study in the realm of economic and social motives— so critical is its import for our democratic way of life—that I shall return to it later even at the expense of cutting short my comments on the merits of the St. Lawrence project itself.
