But, while I must ask my readers in America to expatriate themselves in their imaginations and to look over into this valley as aliens, I wish them to know that I write, though myself in temporary exile, as a son of the Mississippi Valley, as a geographical descendant of France; that my commission is given me of my love for the boundless stretch of prairie and plain whose virgin sod I have broken with my plough; of the lure of the waterways and roads where I have followed the boats and the trails of French voyageurs and coureurs de bois; and of the possessing interest of the epic story of the development of that most virile democracy known to the world. The "Divine River," discovered by the French, ran near the place of my birth. My county was that of "La Salle," a division of the land of the Illinois, "the land of men." The Fort, or the Rock, St. Louis, built by La Salle and Tonty, was only a few miles distant. A little farther, a town, Marquette, stands near the place where the French priest and explorer, Père Marquette, ministered to the Indians. Up-stream, a busy city keeps the name of Joliet on the lips of thousands, though the brave explorer would doubtless not recognize it as his own; and below, the new- made Hennepin Canal makes a shorter course to the Mississippi River than that which leads by the ruins of La Salle's Fort Crèvecoeur. It is of such environment that these chapters were suggested, and it has been by my love for it, rather than by any profound scholarship, that they have been dictated. I write not as a scholar--since most of my life has been spent in action, not in study--but as an academic coureur de bois and of what I have known and seen in the Valley of Democracy, the fairest and most fruitful of the regions where France was pioneer in America.
