You will collect from these documents that the general view of those who have considered the subject appears to be that Moreton Bay would be a convenient rendezvous for the land portion of the Expedition; that they might be conveyed by sea to the mouth of the Victoria River, on the north-west coast; that it would be advantageous, if possible, that they should act in concert with a Government vessel, which might be employed in surveying operations in the Gulf of Carpentaria and neighbourhood, while the land explorers were engaged in the interior. SELECTION OF COMMANDER. Her Majesty's Government are, however, fully aware that such projects, especially where they involve so much combination, can only be submitted generally to the leader of such an expedition, to whom great latitude must be left as to the mode of carrying his instructions into execution. They have now come to the determination of offering the command of the land expedition to Mr. A.C. Gregory, Assistant Surveyor, in Western Australia. They have been induced to take this course both by the very high testimonials which have been given to the abilities and fitness of this gentleman for the purpose by such authorities as they have been able to consult in England, and also by your own reports concerning him, particularly that contained in your despatch of the 6th January, 1852. Should Mr. Gregory accept the charge, which I trust, notwithstanding its arduous and responsible nature, you will find him ready to do, it is the wish of Her Majesty's Government that without waiting for further instructions he should proceed immediately to Sydney, where he will find such instructions awaiting him, and where his party will be organised. You are authorised to supply Mr. Gregory with the necessary funds for this purpose, which will be repaid to the Local Government, from the Commissariat chest. If you are aware of any persons in your Government well qualified and willing to serve under Mr. Gregory in subordinate capacities, or if he has himself any assistants whom he would be anxious to engage, you are at liberty to place them at his disposal; but it must be understood that this permission does not apply to persons who are to take charge of scientific departments of the Expedition, as there are already gentlemen of this class with whom her Majesty's Government have been in correspondence; any such person who may wish to join the Expedition can do so only as a volunteer. Copy of this despatch has been transmitted by the same mail to Sir Charles Fitzroy, and likewise to the other Australian Governors. Sir Charles Fitzroy will therefore be fully prepared to receive Mr. Gregory, and to render him all assistance in his power; and I have every reason to hope for the zealous co-operation of the several local Legislatures and Governments in a scheme intended for the development of the vast and unknown resources of their common Continent.
