La Salle and the Discovery of the Great West, France and England in North America

When the earlier editions of this book were published, I was aware of the existence of a collection of documents relating to La Salle, and containing important material to which I had not succeeded in gaining access. This collection was in possession of M. Pierre Margry, director of the Archives of the Marine and Colonies at Paris, and was the result of more than thirty years of research.
