Niverville was taken seriously ill, and had to remain at Fort Paskoyac, while some of his men in the spring of 1751 ascended the Saskatchewan in canoes. These men, we are told, paddled up the river to the foot of the Rocky Mountains, where they built a fort, named Fort La Jonquière, in honour of the governor. Later in the year Niverville followed his men up the river. At Fort La Jonquière he met a party of Western Indians, who told him that in the course of a war expedition they had encountered a number of Indians of a strange tribe carrying loads of beaver skins. These strange Indians told the Frenchmen that they were on their way over the Rocky Mountains to trade their furs with white men on the sea-coast. For some reason, either through lack of supplies or because he did not possess the courage and enthusiasm which had carried the La Vérendryes through so many difficulties, Niverville made no effort to cross the mountains. This attempt to reach the Western Sea ended, so far as French {109} explorers were concerned, at Fort La Jonquière. All the toils and hardships of the French explorers ended in failure to achieve the great end at which they aimed. Members of another race reaped the coveted reward. Many years later a Scottish-Canadian explorer, Alexander Mackenzie, realized La Vérendrye's dream by successfully crossing the Rocky Mountains and forcing his way through the difficult country that lay beyond, until at last he stood upon the shores of the Pacific ocean. Meanwhile Saint-Pierre had remained at Fort La Reine, leaving the work of exploration to his young lieutenant, Niverville. One incident of his life there remains to be described before we close this story of the search for the Western Sea. It cannot be better told than in Saint-Pierre's own narrative: On February 22, 1752 [he says], about nine o'clock in the morning, I was at this post with five Frenchmen. I had sent the rest of my people, consisting of fourteen persons, to look for provisions, of which I had been in need for several days. I was sitting quietly in my room, when two hundred Assiniboines entered the fort, all of them armed. These Indians scattered immediately all through the place; several {110} of them even entered my room, but unarmed; others remained in adjacent parts of the fort. My people came to warn me of the behaviour of these Indians. I ran to them and told them sharply that they were very impudent to come in a crowd to my house, and armed. One of them answered in the Cree language that they came to smoke. I told them that they were not behaving properly, and that they must leave the fort at once. I believe that the firmness with which I spoke somewhat frightened them, especially as I put four of the most resolute out of the door, without their saying a word.
