After having been approached to write an article on George Fletcher Moore's contribution to Western Australia in the pre-convict period (published as Ambitions's Fire: The Agricultural Colonization of Pre-Convict Western Australia (1981)), J. M. R. Cameron went back to Moore's original letters held by the J. S. Battye Library of Western Australian History in Perth, Western Australia. Here Cameron found much material not published in the 1834 version edited by Martin Doyle, or the 1880-1882 serialisation edited by Thomas Cockburn-Campbell and the subsequent selected work compiled by Moore and published by Walbrook in 1884.

'The text of the book is derived from three main sources ... As far as possible the text is based on George Fletcher Moore's surviving letters and journals ['held by the J S Battye Library of Western Australian History as Original Letters and Journals (BL263)']. Gaps ... have been covered up to the end of July 1833 by drawing on Martin Doyle's edited Extracts and, after 20 February 1834, from Sir Thomas Cockburn Campbell's edited version of the journals as serialised in the West Australian. This latter is supplemented whenever possible by surviving remnants of the journal transcipts [J S Battye Library of Western Australian History 'Transcripts from Moore's Journals (BL1151A)'] used by Campbell but not published in his newspaper ... the Diary of Ten Years has been used as reference point for both sources.
