But how was La Salle employed in the following year? The same memoir has its solution to the problem. By this it appears that the indefatigable explorer embarked on Lake Erie, ascended the Detroit to Lake Huron, coasted the unknown shores of Michigan, passed the Straits of Michillimackinac, and leaving Green Bay behind him, entered what is described as an incomparably larger bay, but which was evidently the southern portion of Lake Michigan. Thence he crossed to a river flowing westward,—evidently the Illinois,—and followed it until it was joined by another river flowing from the northwest to the southeast. By this, the Mississippi only can be meant; and he is reported to have said that he descended it to the thirty-sixth degree of latitude; where he stopped, assured that it discharged itself not into the Gulf of California, but into the Gulf of Mexico; and resolved to follow it thither at a future day, when better provided with men and supplies. [Footnote: The memoir,– after stating, as above, that he entered Lake Huron, doubled the peninsula of Michigan, and passed La Baye des Puants (Green Bay),—says, "Il reconnut une baye incomparablement plus large; au fond de laquelle vers l'ouest il trouva un trés-beau havre et au fond de ce havre un fleuve qui va de l'est à l'ouest. Il suivit ce fleuve, et estant parvenu jusqu'environ le 280me degré de longitude et le 39me de latitude, il trouva un autre fleuve qui se joignant au premier coulait du nordouest au sud-est, et il suivit ce fleuve jusqu'au 36me degré de latitude."
The "très-beau havre" may have been the entrance of the River Chicago, whence, by an easy portage, he might have reached the Des Plaines branch of the Illinois. We shall see that he took this course in his famous exploration of 1682.
The Intendant Talon announces in his despatches of this year that he had sent La Salle southward and westward to explore.]
The first of these statements,—that relating to the Ohio,—confused, vague, and in great part incorrect as it certainly is, is nevertheless well sustained as regards one essential point. La Salle himself, in a memorial addressed to Count Frontenac in 1677, affirms that he discovered the Ohio, and descended it as far as to a fall which obstructed it. [Footnote: The following are his words (he speaks of himself in the third person): "L'année 1667, et les suivantes, il fit divers voyages avec beaucoup de dépenses, dans lesquels il découvrit le premier beaucoup de pays au sud des grands lacs, et entre autres la grande rivière d'Ohio; il la suivit jusqu'à un endroit ou elle tombe de fort haut dans de vastes marais, a la hauteur de 37 degrés, après avoir été grossie par une autre rivière fort large qui vient du nord; et toutes ces eaux se déchargent selon toutes les apparences dans le Golfe du Mexique."
This "autre riviére," which, it seems, was above the fall, may have been the Miami or the Scioto. There is but one fall on the river, that of Louisville, which is not so high as to deserve to be described as "fort haut," being only a strong rapid. The latitude, as will be seen, is different in the two accounts, and incorrect in both.] Again, his rival, Louis Joliet, whose testimony on this point cannot be suspected, made two maps of the region of the Mississippi and the Great Lakes. The Ohio is laid down on both of them, with an inscription to the effect that it had been explored by La Salle. [Footnote: 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 clans 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.] That he discovered the Ohio may then be regarded as established. That he descended it to the Mississippi, he himself does not pretend; nor is there reason to believe that he did so.
With regard to his alleged voyage down the Illinois, the case is different. Here, he is reported to have made a statement which admits but one interpretation,—that of the discovery by him of the Mississippi prior to its discovery by Joliet and Marquette. This statement is attributed to a man not prone to vaunt his own exploits, who never proclaimed them in print, and whose testimony, even in his own case, must therefore have weight. But it comes to us through the medium of a person, strongly biased in favor of La Salle and against Marquette and the Jesuits.
Seven years had passed since the alleged discovery, and La Salle had not before laid claim to it; although it was matter of notoriety that during five years it had been claimed by Joliet, and that his claim was generally admitted. The correspondence of the Governor and the Intendant is silent as to La Salle's having penetrated to the Mississippi; though the attempt was made under the auspices of the latter, as his own letters declare; while both had the discovery of the great river earnestly at heart. The governor, Frontenac, La Salle's ardent supporter and ally, believed in 1672, as his letters show, that the Mississippi flowed into the Gulf of California, and, two years later, he announces to the minister Colbert its discovery by Joliet. [Footnote: Lettre de Frontenac au Ministre, 14 Nov. 1674. He here speaks of "la grande rivière qu'il (Joliet) a trouvée, qui va du nord au sud, et qui est aussi large que celle du Saint- Laurent vis-à-vis de Québec." Four years later, Frontenac speaks slightingly of Joliet, but neither denies his discovery of the Mississippi nor claims it for La Salle, in whose interest he writes.] After La Salle's death, his brother, his nephew, and his niece addressed a memorial to the King, petitioning for certain grants in consideration of the discoveries of their relative, which they specify at some length; but they do not pretend that he reached the Mississippi before his expeditions of 1679 to 1682.

Il y construisit un fort situé à 350 lieues au-delà du fort de Frontenac, et suivant ensuite le cours de cette rivière, il trouve qu'elle se jettoit dans un grand fleuve appellé par ceux du pays
