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.
