At this point the Mackenzie enters the Rockies, this great spinal mountain-chain of North America breaking into parallel ranges to allow the mighty flood to flow between. We feel, as the boatman did on Lake Athabasca, that a day is as long as you can go without stopping. A ladder takes us to a seat by the side of Tenny Gouley in the pilot-house, who merely drops the window to give us an unobstructed view, and says nothing. Tenny Gouley is one of the rare people who understand. Talk of civilising these half-breeds of the North! They have that gift of repose which we know nothing of, which we may hope to attain after we have lived through automobiles and air-ships and when many incarnations will have allayed the fever of that unrest which we so blatantly dub "progress."
It is an ancient something, this unmapped Mackenzie into whose silence we intrude. Before man was, these waters had cut for themselves a road to the ocean. These banks were once marked by the mammoth. Previous to the Glacial Age, prehistoric man here hunted prehistoric prey; eons passed; and when the Ice Age went out, willows and aspens occupied the silt, delicate flower-growth flourished, and birds sang in the branches.
Three thousand miles of waterway, forest-fringed and rampart-guarded, and of its treasures the world knows naught! They await man's development and acceptance--banks of pitch, wells of oil, outcroppings of coal, great masses of unmined salt, mineral wealth uncounted and unguessed. Silent forests have followed us from where we entered the Athabasca, and these woods persist to where the great river divides into its delta channels. Of the mineral wealth of the Liard, the Peace, the Nahanni, and the half hundred other waterways tributary to the Mackenzie, practically nothing is known. There remain in these streams hundreds of miles unnavigated, and channels innumerable known only to the _inconnu_ and the Indian.
It is one hundred and twenty years since Mackenzie descended this stream to its mouth, "discovering" a river along whose shores centuries before had smoked the watch-fires and risen the tepees of an anterior race, wanderers from Asia, who here, guiltless alike of onlooker or chronicler, lived and loved and worked out their drama of life. Age follows age, a new generation is evolved in the new habitat, and in time these once-migrants from Asia are dubbed "the red men" and "the American Indian."
