Note 22 — Chapter II

One of these maps is entitled Carte de la découverte du Sieur Joliet, 1674. Over the lines representing the Ohio are the words, "Route du sieur de la Salle pour aller dans le Mexique." The other map of Joliet bears, also written over the Ohio, the words, "Rivière par où descendit le sieur de la Salle au sortir du lac Erié pour aller dans le Mexique." I have also another manuscript map, made before the voyage of Joliet and Marquette, and apparently in the year 1673, on which the Ohio is represented as far as to a point a little below Louisville, and over it is written, "Rivière Ohio, ainsy appellée par les Iroquois à cause de sa beauté, par où le sieur de la Salle est descendu." The Mississippi is not represented on this map; but—and this is very significant, as indicating the extent of La Salle's exploration of the following year—a small part of the upper Illinois is laid down.
