The History of the Hudson's Bay Company, 1760-1870, vol. II

From the review attached: " This enormous volume is, like its predecessor, written with great clarity. The subject has changed, from pioneering to the problems of competition and the gains of monopoly; lagging profits in vigorous competition from 1763 to 1821, high profits from the moment that near-monopoly was re-established in the latter year." 161.
