Shortly after his arrival at Montreal, he received from the Superior of the Sulpitian Seminary, which had recently become the feudal lord of that city, a large grant of land (a “seigniory”) in that vicinity.[3] This he immediately proceeded to improve, by the introduction of new settlers as tenants, the erection of buildings, and the cultivation of the soil. It is probable, however, that even before coming to Canada he had outlined to himself a much wider sphere of activity. For, with the prevision which was a feature of his character, he spent much of his time during the first two years of his life at La Chine, in mastering the Indian languages, especially those of the Iroquois and Algonquin dialects. And in this, he evidently struck upon the initial point of his future career. For, from a party of Senecas who visited with him several weeks at his seigniory, he learned of a great river (which they called the Ohio) “flowing into the sea,” and only to be reached by a journey of eight or nine months. This, he conceived, might be the river of which he had already heard as emptying into the “Vermilion Sea,” or Gulf of California, and, thinking that perchance it might possibly prove to be a northwest route to China, he projected a voyage of discovery thither.[4] With this in view he planned a visit to the Senecas, to learn all that they might know in relation to the matter. Communicating his plans to the Governor (Courcelle) and the Intendant (Talon) of Canada, he received from them the necessary authorization to make the attempt. But first, as it must be made at his own expense, and as he had already spent all his means upon the improvement of his seigniory, he was obliged to sell his lands, etc., mainly to the Seminary, from which he had obtained them. He, also, though perhaps rather unfortunately, joined his interests with those of the Sulpitians, in a voyage of discovery which that order were about to make for missionary purposes, in the same direction.
