On the thirteenth of May, 1611, Champlain again arrived in the St. Lawrence. To secure the advantages of the fur-trade to his superiors was now his principal object; and, to that end, he chose the site of the present city of Montreal for a post, which he called Place Royale. Soon afterward, he returned to France; but, early in the spring of 1613, the tireless voyager again crossed the Atlantic, and sailed up the St. Lawrence; this time bound for the Ottawa to discover the North sea. After making his way up that river to the home of the Algonquins of Isle des Allumettes, he returned in disgust to the St. Lawrence, and again embarked for France. At the site of the present city of Montreal, there had assembled, in the summer of 1615, Hurons from their distant villages upon the shores of their great lake, and Algonquins from their homes on the Ottawa--come down to a yearly trade with the French upon the St. Lawrence. Champlain, who had returned in May from France, was asked by the assembled savages to join their bands against the Iroquois. He consented; but, while absent at Quebec, making needful preparations, the savages became impatient, and departed for their homes. With them went Father Joseph le Caron, a Récollet, accompanied by twelve armed Frenchmen. It was the intention of this missionary to learn the language of the Hurons, and labor for their spiritual welfare. His departure from the St. Lawrence was on the first day of July. Nine days afterward, Champlain, with two Frenchmen and ten Indians followed him. Both parties traveled up the Ottawa to the Algonquin villages; passed the two lakes of the Allumettes; threaded their way to a well-trodden portage, crossing which brought them to Lake Nipissing; thence, they floated westward down the current of French river, to what is now known as Georgian bay; afterward, for more than a hundred miles, they journeyed southward along the eastern shores of that bay to its head; and there was the home of the Hurons.
