On returning from Lake Ontario to Quebec Frontenac had good reason to be pleased with his summer's work. It still remained to convince Colbert that the construction of the fort at Cataraqui was not an undue expense and waste of energy. But as the initial outlay had already been made, he had ground for hope that he would not receive a positive order to undo what had been accomplished. At Quebec he received Colbert's disparaging comments upon the assembly of the Three Estates and the substitution of aldermen for the syndic who had formerly represented the inhabitants. These comments, however, were not so couched as to make the governor feel that he had lost the minister's confidence. On the whole, the first year of office had gone very well. A stormier season was now to follow. The battle-royal between Frontenac and Perrot, the governor of Montreal, began in the autumn of 1673 and was waged actively throughout the greater part of 1674. Enough has been said of Frontenac's tastes to show that he was a spendthrift; and there can be no doubt that as governor of Canada he hoped to supplement his salary by private trading. Soon after his arrival at Quebec in the preceding year he had formed an alliance with La Salle. The decision to erect a fort at Cataraqui was made for the double reason that while safeguarding the colony Frontenac and La Salle could both draw profit from the trade at this point in the interior. La Salle was not alone in knowing that those who first met the Indians in the spring secured the best furs at the best bargains. This information was shared by many, including Francois Perrot. Just above the island of Montreal is another island, which lies between Lake St Louis and the Lake of Two Mountains. Perrot, appreciating the advantage of a strategic position, had fixed there his own trading-post, and to this day the island bears his name. Now, with Frontenac as a sleeping partner of La Salle there were all the elements of trouble, for Perrot and Frontenac were rival traders. Both were wrathful men and each had a selfish interest to fight for, quite apart from any dispute as to the jurisdiction of Quebec over Montreal. Under such circumstances the one thing lacking was a ground of action. This Frontenac found in the existing edict against the coureurs de bois-those wild spirits who roamed the woods in the hope of making great profits through the fur trade, from which by law they were excluded, and provoked the special disfavour of the missionary by the scandals of their lives, which gave the Indians a low idea of French morality. Thus in the eyes of both Church and State the coureur de bois was a mauvais sujet, and the offence of taking to the forest without a licence became punishable by death or the galleys.
