"Whereas we think fit that an accurate Survey should be made of the Southern Coasts of the Peninsula of South America, from the southern entrance of the River Plata, round to Chilóe; and of Tierra del Fuego; and whereas we have been induced to repose confidence in you, from your conduct of the Surveys in New Holland; we have placed you in the command of His Majesty's Surveying Vessel the Adventure; and we have directed Captain Stokes, of His Majesty's Surveying Vessel the Beagle, to follow your orders.
"Both these vessels are provided with all the
means which are necessary for the complete execution of the object above-mentioned, and for the health and comfort of their Ships' Companies. You are also furnished with all the information, we at present possess, of the ports which you are to survey; and nine Government Chronometers have been embarked in the Adventure, and three in the Beagle, for the better determination of the Longitudes.
"You are therefore hereby required and directed, as soon as both vessels shall be in all respects ready, to put to sea with them; and on your way to your ulterior destination, you are to make, or call at, the following places, successively; namely; Madeira: Teneriffe: the northern point of St. Antonio, and the anchorage at St. Jago; both in the Cape Verd Islands: the Island of Trinidad, in the Southern Atlantic: and Rio de Janeiro: for the purpose of ascertaining the differences of the longitudes of those several places.
"At Rio de Janeiro, you will receive any supplies you may require; and make with the Commander-in-chief, on that Station, such arrangements as may tend to facilitate your receiving further supplies, in the course of your Expedition.
"After which, you are to proceed to the entrance of the River Plata, to ascertain the longitudes of the Cape Santa Maria, and Monte Video: you are then to proceed to survey the Coasts, Islands, and Straits; from Cape St. Antonio, at the south side
of the River Plata, to Chilóe; on the west coast of America; in such manner and order, as the state of the season, the information you may have received, or other circumstances, may induce you to adopt.
"You are to continue on this service until it shall be completed; taking every opportunity to communicate to our Secretary, and the Commander-in-Chief, your proceedings: and also, whenever you may be able to form any judgment of it, where the Commander-in-Chief, or our Secretary, may be able to communicate with you.
"In addition to any arrangements made with the Admiral, for recruiting your stores, and provisions; you are, of course, at liberty to take all other means, which may be within your reach, for that essential purpose.
"You are to avail yourself of every opportunity of collecting and preserving Specimens of such objects of Natural History as may be new, rare, or interesting; and you are to instruct Captain Stokes, and all the other Officers, to use their best diligence in increasing the Collections in each ship: the whole of which must be understood to belong to the Public.
