22 June 1841
About noon we arrived at Fort Ellice, remaining there three of four hours. At this post, commonly known as Beaver Creek, from the name of the brook on which it stands, we obtained tidings of a large body of emigrants, who had left Red River for the Columbia a few days previously to our arrival from Montreal. They had reached Fort Ellice on the twenty-second of June, and started again the next day. As these people were pursuing the same route as ourselves, and would beat a good track, we resolved, as far as practicable, to follow their trail.
