The map of Lake Superior, published in the Jesuit Relation of 1670, 1671, was made at about the same time with Galinee's map. Lake Superior is here styled "Lac Tracy, on Superieur." Though not so exact as it has been represented, this map indicates that the Jesuits had explored every part of this fresh-water ocean, and that they had a thorough knowledge of the straits connecting the three Upper Lakes, and of the adjacent bays, inlets, and shores. The peninsula of Michigan, ignored by Galinee, is represented in its proper place. About two years after Galinee made the map mentioned above, another, indicating a greatly increased knowledge of the country, was made by some person whose name does not appear, but who seems to have been La Salle himself. This map, which is somewhat more than four feet long and about two feet and a half wide, has no title. All the Great Lakes, through their entire extent, are laid down on it with considerable accuracy. Lake Ontario is called "Lac Ontario, ou de Frontenac." Fort Frontenac is indicated, as well as the Iroquois colonies of the north shore. Niagara is "Chute haute de 120 toises par ou le Lac Erie tombe dans le Lac Frontenac." Lake Erie is "Lac Teiocha-rontiong, dit communement Lac Erie." Lake St. Glair is "Tsiketo, ou Lac de la Chaudiere." Lake Huron is "Lac Huron, ou Mer Douce des Hurons." Lake Superior is "Lac Superieur." Lake Michigan is "Lac Mitchiganong, ou des Illinois." On Lake Michigan, immediately opposite the site of Chicago, are written the words, of which the following is the literal translation: "The largest vessels can come to this place from the outlet of Lake Erie, where it discharges into Lake Frontenac (Ontario); and from this marsh into which they can enter, there is only a distance of a thousand paces to the River La Divine (Des Plaines), which can lead them to the River Colbert (Mississippi), and thence to the Gulf of Mexico." This map was evidently made before the voyage of Joliet and Marquette, and after that voyage of La Salle, in which he discovered the Illinois, or at least the Des Plaines branch of it. It shows that the Mississippi was known to discharge itself into the Gulf before Joliet had explored it. The whole length of the Ohio is laid down with the inscription, "River Ohio, so called by the Iroquois on account of its beauty, which the Sieur de la Salle descended." (_Ante_, p. 23, _note_.)
