Charles MacKenzie and Larocque in their Journals (Masson Coll.) give the details of the Mandane trade. Henry also touches on it.

CHAPTER XXIII

1780-1810

“THE COMING OF THE PEDLARS” CONTINUED—THIRTY YEARS OF EXPLORATION—THE ADVANCE UP THE SASKATCHEWAN TO BOW RIVER AND HOWSE PASS—THE BUILDING OF EDMONTON—HOW MACKENZIE CROSSED TO THE PACIFIC.

While fifty or a hundred men yearly ascended Red River as far as Grand Forks, and the Assiniboine as far as Qu’ Appelle, the main forces of the Nor’Westers—the great army of wood-rovers and plain rangers and swelling, blustering bullies and crafty old wolves of the North, and quiet-spoken wintering partners of iron will, who said little and worked like demons—were destined for the valley of the Saskatchewan that led to the Rockies.

Like a great artery with branches south leading over the height of land to the Missouri and branches north giving canoe passage over the height of land to the Arctic, the Saskatchewan flowed for twelve hundred miles through the fur traders’ stamping ground, freighted with the argosies of a thousand canoes. From the time that the ice broke up in May, canoes were going and coming; canoes with blankets hoisted on a tent pole for sail; canoes of birch bark and cedar dugouts; canoes made of dried buffalo skin stitched and oiled round willow withes the shape of a tub, and propelled across stream by lapping the hand over the side of the frail gun’els. Indians squatted flat in the bottom of the canoes, dipping paddles in short stroke with an ease born of life-long practice. White men sat erect on the thwarts with the long, vigorous paddle-sweep of the English oarsman and shot up and down the swift-flowing waters like birds on wing. The boats of the English traders from Hudson Bay were ponderously clumsy, almost as large as the Mackinaws, which the Company still uses, with a tree or rail plied as rudder to half-punt, half-scull; rows of oarsmen down each side, who stood to the oar where the current was stiff, and a big mast pole for sails when there was wind, for the tracking rope when it was necessary to pull against rapids. Where rapids were too turbulent for tracking, these boats were trundled ashore and rolled across logs. Little wonder the Nor’Westers with their light birch canoes built narrow for speed, light enough to be carried over the longest portage by two men, outraced with a whoop the Hudson’s Bay boats whenever they encountered each other on the Saskatchewan! Did the rival crews camp for the night together, French bullies would challenge the Orkneymen of the Hudson’s Bay to come out and fight. The defeated side must treat the conquerors or suffer a ducking.

Crossing the north end of Lake Winnipeg, canoes bound inland passed Horse Island and ascended the Saskatchewan. Only one interruption broke navigation for one thousand miles—Grand Rapids at the entrance of the river, three miles of which could be tracked, three must be portaged—in all a trail of about nine miles on the north shore where the English had laid a corduroy road of log rollers. The ruins of old Fort Bourbon and Basquia or Pas, where Hendry had seen the French in ’54, were first passed. Then boats came to the metropolis of the Saskatchewan—the gateway port of the great Up Country—Cumberland House on Sturgeon Lake. Here, Hearne had built the post for Hudson’s Bay, and Frobisher the fort for the Nor’Westers. Here, boats could go on up the Saskatchewan, or strike northwest through a chain of lakes past Portage de Traite and Isle a la Crosse to Athabasca and MacKenzie River. Fishing never failed, and when the fur traders went down to headquarters, their families remained at Cumberland House laying up a store of dried fish for the winter. Beyond Cumberland House came those forts famous in Northwest annals, Lower Fort des Prairies, and the old French Nipawi, and Fort a la Corne, and Pitt, and Fort George, and Vermilion, and Fort Saskatchewan and Upper Fort des Prairies or Augustus—many of which have crumbled to ruin, others merged into modern cities like Augustus into Edmonton. On the south branch of the Saskatchewan and between the two rivers were more forts—oases in a wilderness of savagery—Old Chesterfield House where Red Deer River comes in and Upper Bow Fort within a stone’s throw of the modern summer resort at Banff, where grassed mounds and old arrowheads to-day mark the place of the palisades.
