Vast watercourse, boundary, and the gateway to North America - the St. Lawrence River has been an integral player in the formation of Canada as we know it today. But as writer and naturalist Henry Beston reminds us, this great passageway carries much more than historical significance to the wildlife of its waters and banks. Travelling along the river more than 70 years ago, Beston expertly observed its natural environment as he researched the greatest survey of the land and its people that had yet been written. Illustrated with sketches from the Group of Seven's A.Y. Jackson, The St. Lawrence quickly became one of the most beloved titles in the Rivers of America series when it was first published in 1942. The Wynford edition restores to print this classic work of non-fiction, with a new introduction by Beston's biographer, Daniel Payne, to situate the book within its historical context for the modern reader.
