It was the opinion of Champlain that on the banks of the St. Lawrence was the true site of a settlement; that here a fortified post should be erected; that thence, by following up the waters of the interior region to their sources, a western route might be traced to China, the distance being estimated by him at not more than two or three hundred leagues; and that the fur-trade of the whole country might be secured to France by the erection of a fort at some point commanding the river. These views, five years subsequent to his visit to the St. Lawrence, induced the fitting out of a second expedition, for trade, exploration, and colonization. On the thirteenth of April, 1608, Champlain again sailed--this time with men, arms, and stores for a colony. The fur-trade was intrusted to another. The mouth of the Saguenay was reached in June; and, soon after, a settlement was commenced on the brink of the St. Lawrence--the site of the present market-place of the lower town of Quebec. A rigorous winter and great suffering followed. Supplies arrived in the spring, and Champlain determined to enter upon his long-meditated explorations;--the only obstacles in the way were the savage nations he would every-where meet. He would be compelled to resort to diplomacy--to unite a friendly tribe to his interests, and, thus strengthened, to conquer, by force of arms, the hostile one. The tribes of the Hurons, who dwelt on the lake which now bears their name, and their allies, the Algonquins, upon the Ottawa and the St. Lawrence, Champlain learned, were at war with the Iroquois, or Five Nations, whose homes were within the present State of New York. In June, 1609, he advanced, with sixty Hurons and Algonquins and two white men, up what is now known as the Richelieu river to the discovery of the first of the great lakes--the one which now bears his name. Upon its placid waters, this courageous band was stopped by a war-party of Iroquois. On shore, the contending forces met, when a few discharges of an arquebuse sent the advancing enemy in wild dismay back into the forest. The victory was complete. Promptly Champlain returned to the St. Lawrence, and his allies to their homes, not, however, until the latter had invited the former to visit their towns and aid them again in their wars. Champlain then revisited France, but the year 1610 found him once more in the St. Lawrence, with two objects in view: one, to proceed northward, to explore Hudson's bay; the other, to go westward, and examine the great lakes and the mines of copper on their shores, of the existence of which he had just been informed by the savages; for he was determined he would never cease his explorations until he had penetrated to the western sea, or that of the north, so as to open the way to China. But, after fighting a battle with the Iroquois at the mouth of the river Richelieu, he gave up, for the time, all thought of further exploration, and returned to France.
