John McDonnell, North-West trader of this period, says:--"Fort Tremblant and the temporary posts established above it furnished most of the beaver and otter in the Red River returns, but the trade has been almost ruined since the Hudson's Bay Company entered the Assiniboine River by the way of Swan River, carrying their merchandise from one river to the other on horseback--three days' journey--who by that means, and the short distance between Swan River and their factory at York Fort, from whence they are equipped, can arrive at the _coude de l'homme_ (a river bend or angle) in the Assiniboine River, a month sooner than we can return from Grand Portage, secure the fall trade, give credits to the Indians, and send them to hunt before our arrival; so that we see but few in that quarter upon our arrival." The chief trader of this locality was Cuthbert Grant, who, as before mentioned, was a man of great influence in the fur trade. The astronomer next went to the Fort between the Swan and Assiniboine Rivers, near the spot where the famous Fort Pelly of the present day is situated. Taking horses, a rapid land journey was made to Belleau's Fort, lying in 53 deg. N. latitude (nearly). The whole district is a succession of beaver meadows, and had at this time several Hudson's Bay Company posts, as already mentioned. Thompson decided to winter in this beaver country, and when the following summer had fairly set in with good roads and blossoming prairies, he came, after journeying more than 200 miles southward, to the Qu'Appelle River post, which was at that time under a trader named Thorburn. Thompson was now fairly on the Assiniboine River, and saw it everywhere run through an agreeable country with a good soil and adapted to agriculture. Arrived at Assiniboine House, he found it in charge of John McDonnell, brother of the well-known Miles McDonnell, who, a few years later, became Lord Selkirk's first governor on Red River. Ensconcing himself in the comfortable quarters at Assiniboine House, Thompson wrote up in ink his journals, maps, astronomical observations, and sketches which he had taken in crayon, thus giving them more permanent form. He had now been in the employ of the North-West Company a full year, and in that time had been fully gratified by the work he had done and by the cordial reception given him in all the forts to which he had gone. Assiniboine House, or, as he called it, Stone Indian House, was found to be a congenial spot. It was on the north side of the Assiniboine River, not far from where the Souris River empties its waters into the larger stream, though the site has been disputed. One of the astronomer's clearly defined directions was to visit the Mandan villages on the Missouri River. He was now at the point when this could be accomplished, although the time chosen by him, just as winter was coming on, was most unsuitable. His journey reminds us of that made by Verendrye to the Mandans in 1738.
