That La Salle came to Canada with objects distinctly in view, is probable from the fact that he at once began to study the Indian languages, and with such success that he is said, within two or three years, to have mastered the Iroquois and seven or eight other languages and dialects. [Footnote: _Papiers de Famille_, MSS. He is said to have made several journeys into the forests, towards the North, in the years 1667 and 1668, and to have satisfied himself that little could be hoped from explorations in that direction.] From the shore of his seigniory, he could gaze westward over the broad breast of the Lake of St. Louis, bounded by the dim forests of Chateauguay and Beauharnois; but his thoughts flew far beyond, across the wild and lonely world that stretched towards the sunset. Like Champlain and all the early explorers, he dreamed of a passage to the South Sea, and a new road for commerce to the riches of China and Japan. Indians often came to his secluded settlement; and, on one occasion, he was visited by a band of the Seneca Iroquois, not long before the scourge of the colony, but now, in virtue of the treaty, wearing the semblance of friendship. The visitors spent the winter with him, and told him of a river called the Ohio, rising in their country, and flowing into the sea, but at such a distance that its mouth could only be reached after a journey of eight or nine months. Evidently, the Ohio and the Mississippi are here merged into one. [Footnote: According to Dollier de Casson, who had good opportunities of knowing, the Iroquois always called the Mississippi the Ohio, while the Algonquins gave it its present name.] In accordance with geographical views then prevalent, he conceived that this great river must needs flow into the "Vermilion Sea;" that is, the Gulf of California. If so, it would give him what he sought,--a western passage to China; while, in any case, the populous Indian tribes said to inhabit its banks, might be made a source of great commercial profit.
