On the arrival at Tadoussac, preparations were at once made for an exploration of the St. Lawrence. While these were in progress, Champlain explored the Saguenay for the distance of thirty or forty miles, noting its extraordinary character, its profound depth, its rapid current, and impressed with the lofty and sterile mountains between whose perpendicular walls its pent-up waters had forced their way, moving down to the ocean with a heavy and irresistible flood. This survey of the Saguenay was probably the first ever made by a European explorer. At all events, Champlain’s description is the earliest which has come down to us. On the 18th of June, leaving Tadoussac in a barque, and taking with them a skiff made expressly for ascending rapids and penetrating shallow streams, Champlain, Pont Gravé, and a complement of sailors, with several Indians as guides and assistants, proceeded up the St. Lawrence. From Tadoussac to Montreal they explored the bays and tributary rivers, observing the character of the soil, the forests, the animal and vegetable products, including all the elements of present and prospective wealth. On reaching the Lachine Rapids above Montreal, their progress was abruptly terminated. Neither their barque nor their skiff could stem the current. They continued on foot along the shore for several miles, but soon found it inexpedient with their present equipment to proceed farther. Having obtained from the Indians important, if not very definite, information concerning the country, rivers, and lakes above the falls, and having likewise learned from them that in the lake region far to the north native copper existed and had been fabricated into articles of ornament, they returned to Tadoussac. Champlain immediately organized another party to examine the southern shore of the Gulf of St. Lawrence. Skirting along the coast, they touched at Gaspé, Mal-Bay, and Isle Percée, which were at that time (1603) important stations, annually visited by fishermen of different nations. Soon after reaching the southern coast they met a troop of savages who were transporting arrows and moose-meat to exchange for the skins of the beaver and marten with the more northern tribes whom they expected to find at Tadoussac. Having obtained such information as they desired of the country still farther south, and of the copper mines in the region about the Bay of Fundy, Champlain’s party passed directly from Gaspé to the northern side of the Gulf, touching somewhere near the Seven Islands, and thence coasted along the inhospitable shores of the northern side till they reached the harbor of Tadoussac. Having completed their explorations and secured a valuable cargo of furs, which was a subordinate purpose of the expedition, they returned to France, arriving at Havre de Grâce on the 20th of September, 1603.
