the Iroquois, destroyers of the Hurons, requested the French to send missionaries among them, and for nearly twenty years the zealous Jesuits brought about a lull in the sanguinary conflicts of the Five Nations, but at the end of that time when war flamed out anew they were compelled to abandon their missions. Meanwhile, along the Upper Lakes, the missionary movement was being prosecuted with extreme vigour. Garreau and Claude Allouez, with other missionaries, worked along the shores of Superior, establishing missions among the Sacs and Foxes and Pottawatomies. In 1668, Marquette established his famous mission at Sault Ste. Marie, and three years later founded the mission of St. Ignace on the Straits of Mackinaw. It would take a volume to describe the adventures of these early Fighters of the Faith, their trials and sacrifices, their successes and failures. The briefness of our sketch compels us to move quickly from these absorbing scenes to the first great event in the history of Lake navigation, and to the beginning of that encroachment of the English which was to develop a hundred years of war along the Inland Seas. While the Jesuit Fathers were sacrificing their lives among the savages and while the Indian wars of extermination were still in progress, the French farther east had already begun to feel the hostile influence of the English. To check this influence La Salle and Count Frontenac brought about the erection of Fort Frontenac, in 1673, on the present site of Kingston. At this time, Robert Cavelier, Sieur de la Salle, a young man of eminence and learning, was of the supreme faith that he was destined to discover a water passage through the American continent to China and Japan, and the building of Fort Frontenac was only the first step in the gigantic scheme which he planned to carry out. A part of this scheme was the building of a vessel of considerable size in which La Salle planned not only to make a complete tour of the Lakes but in which he hoped to discover the route that would lead to the Orient. Five years later, the young adventurer made the portage around Niagara Falls, and at the mouth of Cayuga Creek, in Niagara County, New York, where is now located the town of La Salle, he began the construction of the first vessel ever to sail the Inland Seas.
