Quote: "In the following pages I have told the story of that body of adventurers who, from 1822 to 1829, opened the way for the expansion of our nation beyond the Missouri. I have made Jedediah Smith the central figure of my story, for of all explorers of the Great West he was in many ways the most remarkable, though, heretofore, our school children have not even heard his name. In order to give the student a sense of the continuity of history, I have begun my narrative with a brief account of the movement across the Alleghenies and down the Ohio River after the Revolutionary War; and I have suggested the relation of westward expansion in America to the whole race movement from the beginning."
