Various adventures signalled the progress of the explorers along the shores of Lake Michigan, as far as the mouth of the St. Joseph, which had been chosen for the final point of departure. The autumn season was well advanced. Already the north wind blew keen and cold across the lake. The canoes were tossed about on a stormy sea, which broke with violence against the inhospitable coast, threatening shipwreck if they approached it. Often the canoes would be swamped in the surf when the rising sea made it dangerous to keep the lake. Often the explorers threw themselves on the frozen ground at night, wet to the skin and famishing with hunger. Reaching the St. Joseph, La Salle set his men to work building a fort, while he anxiously waited the coming of Tonty, who had been ordered to join him at this place. At last Tonty came. Winter had now set in. In the first days of December the united party paddled up the St. Joseph, crossed over the portage to the Kankakee, descended it to the Illinois, reaching at length the great Illinois town,[2] numbering, by actual count, four hundred and sixty lodges. To their great disappointment the town was deserted, all the Illinois having gone to hunt the buffalo, as their custom was at this season of the year. It was a heavy blow to La Salle, who had expected to get guides and a supply of food here, as well as to recruit his men. The explorers however obtained a supply by opening the _caches_[3] in which the Illinois kept their winter store. Somewhere below Peoria Lake, La Salle fell in with the Illinois, who told him all the fables they could invent in order to prevent his going on, for it seems they had some inkling his doing so would be prejudicial to them in the future. The Mississippi, they said, was beset by men of fierce aspect who would kill them all, its waters infested with serpents, alligators and like monsters lying in wait to devour them, while the river itself finally plunged into a raging whirlpool in which they and their canoes would be swallowed up. Although La Salle treated these silly tales with the contempt they deserved, they took effect upon his men, six of whom deserted on the spot. The explorers wintered among these Illinois in a fort which La Salle significantly named Crèvecœur.[4] The name tells its own story. On the lakes they had been nearly drowned. On the march they had often gone hungry, La Salle with the rest. Treason was with him in his own camp, danger in that of the Illinois. His own men had tried to poison him. And now, to cap the climax of misfortune, no word had come of the Griffin[5]—the Griffin on which hung all hope of successfully continuing their search.
