The file consists of 7 letters and 4 transcripts of Ogden's outward correspondence from 1831 to 1849. Correspondence is addressed to a variety of recipients, including John Haldane, William F. Tolmie, John McLeod, Donald Ross, and Ogden's son-in-law Archibald McKinlay, as well as several unidentified correspondents. The file also includes an extract from Ogden's letters to Chief Traders Tod and Mansion in 1845. Although described as a holograph, it appears to be in a different hand than Ogden's. Correspondence deals with a variety of private and Company matters.
Transcripts have been placed in a separate folder for conservation purposes. Not all letters have accompanying transcripts. Some transcripts appear to be copied from John McLeod's "Journals and correspondence of John McLeod, Senior, Chief trader, Hudson's Bay Company."
