18 Sir ALEXANDER MACKENZIE trading under totally different conditions at Detroit, and with only a few trained men among his French Canadians, was called on to take up his station nearly fifteen hundred miles beyond Grand Portage, build his posts, and secure his furs, all in face of powerful rivals already in possession of the field. The animosity between the companies had not broken out openly at Grand Portage, but it soon appeared in the interior. The general results may be given in Mackenzie’s own words: After the severest struggle ever known in that part of the world, and suffering every oppression which a jealous and rival spirit could instigate; after the murder of one of our partners, the laming of another, and the nar- row escape of one of our clerks, who received a bullet through his powder horn in the exe- cution of his duty, they were compelled to allow us a share of the trade. As we had al- ready incurred a loss, this union was, in every respect, a desirable event to us, and was con- cluded in the month of July, 1787. Though the struggle was keen, there was no resort to force in Mackenzie’s own district.
