Interest of this book is not so much for his journal, but the account in the text by Kenney of the fate of Captain Knight. After he left the HBC governorship, he organized an expedition to the west coast of Hudson Bay in search of copper and gold (cf. Frobisher and Borchgrevink), as well as for the NW Passage. Evidently his ships were damaged on the western shore of Marble Island where after two winters all the crew had died, facts which did not come to light for some time. Since he made this voyage without telling the local HBC about his activities, he was not likely to be found. (see esp. p. 75-89).
Would make a good topic to collate the various accounts of this failed expedition.
