The wheels of progress grind slowly, especially where governments, industry pressure groups, and huge expenditures are concerned. The story of the St. Lawrence Seaway began to take shape in 1932, when Canada opened the Welland Canal, first means for letting the ships of the world into the center of the continent. The last major segment, the St. Lawrence Canals, opened in the spring of 1959, is far from the last chapter of this imposing industrial saga. Mabee has carefully analyzed (and documented) the reasons why the Seaway was so long a- building; he is somewhat critical of the delaying tactics on both sides of the national fence. But the white glow of excitement pervades every page. The value of the Seaway is incalculable for Canada, the United States, and the rest of the world; its completion is an achievement ranking high on the list of things that point to man's eventual complete domination over his surroundings. Understanding the project better, as this book helps one to do, takes some of the sting out of the tax bite.
