The usual incidents of early travel were experienced. The accidents, though not serious, were numerous; the scenes met with were all new; the natives were surprised at the bearded stranger; the usual deception and fickleness were displayed by the Indians, only to be overcome by the firmness and tact of Mackenzie; and forty days after starting, the expedition looked out upon the floating ice of the Arctic Ocean. Mackenzie, on the morning of July 14th, erected a post on the shore, on which he engraved the latitude of the place (69 deg. 14´ N.), his own name, the number of persons in the party, and the time they remained there.
His object having been thus accomplished, the important matter was to reach Lake Athabasca in the remaining days of the open season. The return journey had the usual experiences, and on August 24th they came upon Leroux on Slave Lake, where that trader had erected Fort Providence. On September 12th the expedition arrived safely at Fort Chipewyan, the time of absence having been 102 days. The story of this journey is given in a graphic and unaffected manner by Mackenzie in his work of 1801, but no mention is made of his own name being attached to the river which he had discovered.
We have stated that Peter Pond had prepared a map of the north country, with the purpose of presenting it to the Empress of Russia. Being a man of great energy, he was not deterred from this undertaking by the fact that he had no knowledge of astronomical instruments and little of the art of map-making. His statements were made on the basis of reports from the Indians, whose custom was always to make the leagues short, that they might boast of the length of their journeys. Computing in this way, he made Lake Athabasca so far from Hudson Bay and the Grand Portage that, taking Captain Cook's observations on the Pacific Coast four years before this, the lake was only, according to his calculations, a hundred or a hundred and fifty miles from the Pacific Ocean.
The effect of Pond's calculations, which became known in the Treaty of Paris, was to stimulate the Hudson's Bay Company to follow up Hearne's discoveries and to explore the country west of Lake Athabasca. They attempted this in 1785, but they sent out a boy of fifteen, named George Charles, who had been one year at a mathematical school, and had never made there more than simple observations. As was to have been expected, the boy proved incompetent. Urged on by the Colonial Office, they again in 1791 organized an expedition to send Astronomer Philip Turnor to make the western journey. Unaccustomed to the Far West, and poorly provided for this journey, Turner found himself at Fort Chipewyan entirely dependent for help and shelter on the Nor'-Westers. He was, however, qualified for his work, and made correct observations, which settled the question of the distance of the Pacific Ocean. Mr. Roderick McKenzie showed him every hospitality. This expedition served at least to show that the Pacific was certainly five times the distance from Lake Athabasca that Pond had estimated.
After coming back from the Arctic Sea, Alexander Mackenzie spent his time in urging forward the business of the fur trade, especially north of Lake Athabasca; but there was burning in his breast the desire to be the discoverer of the Western Sea. The voyage of Turner made him still more desirous of going to the West.
Like Hearne, Alexander Mackenzie had found the want of astronomical knowledge and the lack of suitable instruments a great drawback in determining his whereabouts from day to day. With remarkable energy, he, in the year 1791, journeyed eastward to Canada, crossed the Atlantic Ocean to London, and spent the winter in acquiring the requisite mathematical knowledge and a sufficient acquaintance with instruments to enable him to take observations.
He was now prepared to make his journey to the Pacific Ocean. He states that the courage of his party had been kept up on their reaching the Arctic Sea, by the thought that they were approaching the Mer de l'Ouest, which, it will be remembered, Verendrye had sought with such passionate desire.
In the very year in which Mackenzie returned from Great Britain, his great purpose to reach the Pacific Coast led him to make his preparations in the autumn, and on October 10th, 1792, to leave Fort Chipewyan and proceed as far up Peace River as the farthest settlement, and there winter, to be ready for an early start in the following spring. On his way he overtook Mr. Finlay, the younger, and called upon him in his camp near the fort, where he was to trade for the winter. Leaving Mr. Finlay "under several volleys of musketry," Mackenzie pushed on and reached the spot where the men had been despatched in the preceding spring to square timber for a house and cut palisades to fortify it. Here, where the Boncave joins the main branch of the Peace River, the fort was erected. His own house was not ready for occupation before December 23rd, and the body of the men went on after that date to erect five houses for which the material had been prepared. Troubles were plentiful; such as the quarrelsomeness of the natives, the killing of an Indian, and in the latter part of the winter severe cold. In May, Mackenzie despatched six canoes laden with furs for Fort Chipewyan.
The somewhat cool reception that Mackenzie had received from the other partners at Grand Portage, when on a former occasion he had given an account of his voyage to the Arctic Sea, led him to be doubtful whether his confrères would fully approve the great expedition on which he was determined to go. He was comparatively a young man, and he knew that there were many of the traders jealous of him. Still, his determined character led him to hold to his plan, and his great energy urged him to make a name for himself.
