The Right Honourable Earl Bathurst, His Majesty's principal Secretary of State for the Colonies, having in a recent despatch authorised and directed me to select and employ a properly qualified and competent officer belonging to this government, for conducting and leading an expedition for the purpose of prosecuting the discoveries made some time since to the westward of the Blue Mountains of New South Wales, by Mr. George William Evans, deputy surveyor of lands; and reposing especial trust and confidence in your abilities, zeal and diligence, for conducting and leading such an expedition: I do hereby constitute and appoint you in virtue of the powers in me vested, to be chief of the expedition now fitting out to prosecute the discoveries to the westward of the Blue Mountains in the interior of the continent of Australia. You are accordingly to be obeyed and respected as chief of this expedition, and to be governed generally during the continuance of it, by the following instructions. First.--With the view of facilitating the objects of the present expedition, and in justice to his former zealous and successful exertions in making the original discoveries in the interior, to the westward of the Blue Mountains; the Right Honourable the Secretary of State has directed, that in the farther prosecution of these discoveries, Mr. George William Evans, deputy surveyor of lands, should be associated with the person appointed to head and direct the expedition; and to be considered the second in command of it. You are therefore to consider Mr. Evans as next in command to yourself during the progress of the expedition, and to consult with him on all operations and points connected therewith; it being presumed from his local experience in the interior, he will be able to afford you very useful information and assistance. Second.--Exclusive of yourself and Mr. Evans, I have deemed it advisable to permit Mr. Allan Cunningham, one of the King's botanists, (lately sent out to this country, for the purpose of collecting plants and seeds for His Majesty's gardens at Kew), to accompany the expedition. I have also ordered ten other persons to accompany you on the expedition in the various capacities of assistants, or servants; and herewith you will receive a schedule of their names, and respective designations, or employments.
