But the time was not far distant when he was to make a much more extended voyage than he had hitherto accomplished, and with somewhat more important results. In 1672 Count Frontenac came over to Canada and succeeded Courcelle as Governor of the colony. A friendship sprang up between him and La Salle, and they began to form schemes of western enterprise. Erelong we find the latter paying a flying visit to France, and receiving from the King, mainly through his patron's influence, a patent of nobility and a grant of Fort Frontenac--which had just before been founded by the new Governor with imposing ceremonies--together with a large tract of the contiguous territory. Then La Salle's serious troubles may be said to have begun. His grant involved the exclusive right of fur-traffic with the Indians on Lake Ontario, and though trade was a secondary object with him, he nevertheless engaged in it as a means of furthering his more ambitious schemes of exploration. The merchants of Canada, envious of his influence and success, leagued themselves against him, and resolved to accomplish his downfall. The Jesuits also placed themselves in opposition to him, for his avowed projects conflicted with theirs. La Salle aimed at the control of the valleys of the Ohio and the Mississippi, and the usufruct of half a continent. The Jesuits were no longer supreme in Canada. In other words, Canada was no longer simply a mission. It had become a colony. Temporal interests and the civil power were constantly gaining ground. Therefore the Jesuits looked with redoubled solicitude to their missions in the West. They dreaded fur-traders, partly because they interfered with their teachings and perverted their converts, and partly for other reasons. La Salle was a fur-trader, and moreover aimed at occupation and settlement. In short, he was a stumbling block in their path, and they leagued themselves against him. Many of them engaged in underhand dealings with the Indians, and while they refused absolution to all Europeans who sold brandy to the natives, they turned a good many dishonest pennies by selling it themselves. They laid all kinds of traps for La Salle, and did not escape the suspicion of attempting to poison him. It is certain that an attempt to destroy him in this fashion was made, though he himself exonerates the Jesuits from participation in the attempt. In the autumn of 1677 he again sailed for France, and while there procured Royal letters patent authorizing him to prosecute his schemes of western discovery, to erect forts at such places as he might deem expedient, and to enjoy the exclusive right of traffic in buffalo skins. With Henri de Tonty, an Italian officer, as his lieutenant, he soon afterwards returned to Fort Frontenac, whence, in the autumn of 1678, he set out for the Great West.
