In the event of this country being involved in hostilities during your absence, you will take care never to be surprised; but you are to refrain from any act of aggression towards the vessels or settlements of any nation with which we may be at war, as expeditions employed in behalf of discovery and science have always been considered by all civilised communities as acting under a general safeguard. You will consider yourself under the command of Rear-Admiral Inglefield, the Commander-in-Chief of Her Majesty's ships and vessels on the East India station, while you are within the limits of that station; and we have signified to him our desire that he should not divert you from the survey, nor interfere with your proceedings, except under the pressure of strong necessity; and that upon all fit occasions he should order you to be supplied with the stores and provisions of which you may stand in need; and all officers senior to yourself, with whom you may fall in, are hereby directed to give you any assistance which may be requisite. Notwithstanding the 16th article of the 4th section of the 6th chapter of the Admiralty Instructions, you are, besides your reports to your Commander-in-Chief, to send brief accounts to our Secretary of your proceedings, state, and condition: and you will make known to him, in due time, the nature and quantity of any supplies of which you may be absolutely in want, and which may have to be forwarded to you from England. With our Hydrographer you are by every opportunity in your power to keep up a constant correspondence; you are to report to him in full detail all your proceedings; and you are to transmit to him, whenever possible, tracings of all charts and plans that you may have completed, accompanied by sailing directions, and with notices of any facts or discoveries which may be of interest to navigation. Having completed the service herein set forth, you are to return in the Rattlesnake, along with the Bramble, to Spithead, when you will receive directions for your further proceedings. If the Bramble should, however, by that time be in an unfit state to undertake the voyage to Europe, it may perhaps be prudent to dispose of her, under the sanction of the Commander-in-Chief. In the event of any unfortunate accident befalling yourself, the officer on whom the command may in consequence devolve, is hereby required and directed to carry out, as far as in him lies, the foregoing orders and instructions. Given under our hands, this 1st December 1846. Signed: CHARLES ADAM. JNO. D. DUNDAS. To OWEN STANLEY, Esquire, Captain of her Majesty's Surveying Vessel Rattlesnake, at Plymouth, By command of their Lordships, Signed: H.G. WARD. ... HYDROGRAPHER'S INSTRUCTIONS. In connection with the preceding general instructions to Captain Stanley, it will be necessary to give a portion of those more explicit directions furnished by the Hydrographer, Rear-Admiral Sir Francis Beaufort.
