The evidence of his having, on this voyage, reached and descended the Mississippi is not so clear. What militates most strongly against the assumption that he did so, is the fact, that, though he kept journals and made maps of this trip, which were, as late as 1765, in possession of a niece then living in France, at an advanced age; yet, when, after La Salle's death, this niece together with an uncle and a nephew of the explorer petitioned the King for a certain grant in consideration of the discoveries made by their distinguished relative, they made no mention of such discovery, as they would most likely have done if they had known of it.
But the discovery of the Illinois river must, undoubtedly, be credited to him.
Returning to Canada, from his long wanderings, he found great changes going on in that country. It was no longer simply a missionary field, but was fast assuming the form and character of a colony. A royal Viceroy, or Governor-General, had taken the place of the former Governor and Intendant; and the controlling interests of the Sulpitian order were now largely overshadowed by those of the Jesuits.
