Scurvy and cold plagued the colonists even more than Basque pirates, Hollanders and other poaching foreigners annoyed the company’s traders. Trade was brisk nevertheless, with the furriers and hatters of Rouen and Paris bidding up all the pelts that could be shipped to France. In fact, prices rose so high that the Hatters Corporation of Paris complained to the ministry. Meanwhile, Champlain explored to the south of the French settlements as far as Cape Cod for better sites. He found that Englishmen had been investigating that coast, but he didn’t discover a river that led inland to the lake country, skirting the terrible Iroquois. He didn’t look south far enough. If he had found the Connecticut or the Hudson, New England might today be populated by Frenchmen. And New Yorkers probably wouldn’t have their Dutch ancestors. In the end Champlain advised the king and the merchants that the company should return to the St. Lawrence valley. Trading posts should be established there, he said. With the help of native enemies of the Iroquois he believed he could defeat the Five Nations--force them to trade--force a way through to Tartary or the western sea. This is what the company now proceeded to do. An expedition was sent to the St. Lawrence in 1608. Dupont-Grave traded at Tadoussac with one ship while Champlain in another set out to erect a factory at Quebec. There, at the foot of the cliff where the river was narrow, he built a trading post fort consisting of a two-story wooden building surrounded by a large moat. Cannon which would carry across the river were placed on mounds at the corners, and the surrounding land was cleared of timber and brush against attack. The going was rough, for _le capitaine_ tolerated no shirking of toil. Some of his men conspired to murder him by poison, and, should that fail, by “a traine of gunpowder.” This plot, he discovered in the nick of time. One of the mutineers was hanged; the others were shipped back to France, condemned to the galleys. When the trading ships with their cargoes of beaver and “blacke Foxes, which seeme to exceede Sables” returned to France in the fall, Champlain remained behind at Quebec with twenty-eight men. But scurvy and dysentery took its usual toll. Only eight remained by spring. Nevertheless the French captain proceeded with his plan to invade the country of the Iroquois. He made overtures to their ancient enemies, the Montagnais and the Algonkin Indians.
