It is hard to estimate all the obstacles overcome and the great service rendered in the two voyages of Alexander Mackenzie. Readers of the "North-West Passage by Land" will remember the pitiable plight in which Lord Milton and Dr. Cheadle, nearly seventy years afterwards, reached the coast. Mackenzie's journey was more difficult, but the advantage lay with the fur-traders in that they were experts in the matters of North-West travel. Time and again, Mackenzie's party became discouraged. When the Pacific slope was reached, and the voyageurs saw the waters begin to run away from the country with which they were acquainted, their fears were aroused, and it was natural that they should be unwilling to proceed further.
Mackenzie had, however, all the instincts of a brave and tactful leader. On one occasion he was compelled to take a stand and declare that if his party deserted him, he would go on alone. This at once aroused their admiration and sympathy, and they offered to follow him. At the point on the great river where he turned back, the Indians were exceedingly hostile. His firmness and perfect self-control showed the same spirit that is found in all great leaders in dealing with savage or semi-civilized races. Men like Frontenac, Mackenzie, and General Gordon seemed to have a charmed life which enabled them to exercise a species of mesmeric influence over half-trained or entirely uncultivated minds.
From the wider standpoint, knowledge was supplied as to the country lying between the two great oceans, and while it did not, as we know from the voyages seeking a North-West Passage in this century, lay the grim spectre of an Arctic channel, yet it was a fulfilment of Verendrye's dream, and to Alexander Mackenzie, a Canadian bourgeois, a self-made man, aided by his Scotch and French associates, had come the happy opportunity of discovering "La Grande Mer de l'Ouest."
Alexander Mackenzie, filled with the sense of the importance of his discovery, determined to give it to the world, and spent the winter at Fort Chipewyan in preparing the material. In this he was much assisted by his cousin, Roderick McKenzie, to whom he sent the journal for revision and improvement. Early in the year 1794, the distinguished explorer left Lake Athabasca, journeyed over to Grand Portage, and a year afterward revisited his native land. He never returned to the "Upper Country," as the Athabasca region was called, but became one of the agents of the fur-traders in Montreal, never coming farther toward the North-west than to be present at the annual gatherings of the traders at Grand Portage. The veteran explorer continued in this position till the time when he crossed the Atlantic and published his well-known "Voyages from Montreal," dedicated to "His Most Sacred Majesty George the Third." The book, while making no pretensions to literary attainment, is yet a clear, succinct, and valuable account of the fur trade and his own expeditions. It was the work which excited the interest of Lord Selkirk in Rupert's Land and which has become a recognized authority.
