We learn from Umfreville's book that "he succeeded in his expedition much to the satisfaction of the merchants," along the route from Lake Nepigon to Winnipeg River. The route discovered proved almost impracticable for trade, but as it was many years before the terms of the treaty were carried into effect, Grand Portage remained for the time the favourite pathway to the interior.

The conflict of the two Montreal companies almost obscured that with the English traders from Hudson Bay. True, in some districts the competition was peaceful and honourable. The nephew of Simon McTavish, William McGillivray, who afterwards rose to great prominence as a trader, was stationed with one of the rival company, Roderick McKenzie, of whom we have spoken, on the English River. In 1786 they had both succeeded so well in trade that, forming their men into two brigades, they returned together, making the woods resound with the lively French songs of the voyageurs.

The attitude of the traders largely depended, however, on the character of the men. To the Athabasca district the impetuous and intractable Pond was sent by the older Company, on his desertion to it. Here there was the powerful influence of the Hudson's Bay Company to contend against, and the old Company from the Bay long maintained its hold on the Northern Indians. To make a flank movement upon the Hudson's Bay Company he sent Cuthbert Grant and a French trader to Slave Lake, on which they established Fort Resolution, while, pushing on still farther, they reached a point afterwards known as Fort Providence.

The third body to be represented in Athabasca Lake was the small North-West Company by their bourgeois, John Ross. Ross was a peaceable and fair man, but Pond so stirred up strife that the employés of the two Companies were in a perpetual quarrel. In one of these conflicts Ross was unfortunately killed. This added to the evil reputation of Pond, who in 1781 had been charged with the murder of a peaceful trader named Wadin, in the same Athabasca region.

When Roderick McKenzie heard at Ile à la Crosse of the murder, he hastened to the meeting of the traders at Grand Portage. This alarming event so affected the traders that the two Companies agreed to unite. The union was effected in 1787, and the business at headquarters in Montreal was now managed by the three houses of McTavish, Frobisher, and Gregory. Alexander Mackenzie was despatched to Athabasca to take the place of the unfortunate trader Ross, and so became acquainted with the region which was to be the scene of his triumphs in discovery.

The union of the North-West fur companies led to extension in some directions. The Assiniboine Valley, in one of the most fertile parts of the country, was more fully occupied. As in the case of the Hudson's Bay Company, the occupation of this valley took place by first coming to Lake Winnipeg and ascending the Swan River (always a fur trader's paradise), until, by a short portage, the Upper Assiniboine was reached.

The oldest fort in this valley belonging to the Nor'-Westers seems to have been built by a trader, Robert Grant, a year or two after 1780. It is declared by trader John McDonnell to have been two short days' march from the junction of the Qu'Appelle and Assiniboine.

Well up the Assiniboine, and not far from the source of the Swan River, stood Fort Alexandria, "surrounded by groves of birch, poplar, and aspen," and said to have been named after Sir Alexander Mackenzie. It was 256 feet in length by 196 feet in breadth; the "houses, stores, &c., being well built, plastered on the inside and outside, and washed over with a white earth, which answers nearly as well as lime for white-washing."

Connected with this region was the name of a famous trader, Cuthbert Grant, the father of the leader of the half-breeds and Nor'-Westers, of whom we shall speak afterwards. At the mouth of Shell River on the Assiniboine stood a small fort built by Peter Grant in 1794.

When the Nor'-Westers became acquainted with the route down the Assiniboine, they followed it to its mouth, and from that point, where it joined the Red River, descended to Lake Winnipeg and crossed to the Winnipeg River.
