You will then turn to the westward, and pursue this part of the survey, so as to determine the breadth of the foul ground off the coast of New Guinea, and the continuity or interrupted form of that coast; and you will establish certain positions on the mainland (if the adjacent sea be navigable, and if not on the several advancing islands) which may serve as useful land-falls for vessels coming from the Indian Seas, or for points of departure for those who have passed through any of these straits. You will thus continue a general examination of this hitherto unexplored coast as far as Cape Valsche, which is now said to be only the terminating point of a chain of large islands, and then across to the Arrou Islands, which are supposed to be remarkably fertile, to abound with resources and refreshments, and to be peopled by a harmless and industrious race, but which do not appear to have been visited by any of His Majesty's ships. The length of time which may be required for the due execution of all the foregoing objects cannot be foreseen. It may exceed that for which your supplies are calculated, or, on the other hand, a less degree of the supposed complexity in the ground you will have traversed, along with the energy and diligence with which we rely on you for conducting these important services, may enable you to complete them within that period. In this latter case you will return to the Northern coast of New Holland, and selecting such parts of it as may afford useful harbours of retreat, or which may appear to comprise the mouths of any streams of magnitude, you will employ your spare time in such discoveries as may more or less tend to the general object of the expedition. Before your departure from Sydney you will have learnt that His Majesty's Government has established a new settlement at Port Essington, or somewhere on the North coast of New Holland; and before you finally abandon that district you will visit this new colony, and contribute by every means in your power to its resources and its stability. We have not, in the concluding part of these Orders, pointed out the places or the periods at which you are to replenish your provisions, because the latter must depend on various circumstances which cannot be foreseen, and the former may be safely left to your own decision and prudence; but when you have been three years on your ground, unless some very important result were to promise itself from an extension of that period, you will proceed to the Island of Mauritius, in order to complete your stock of water and provisions, and then, touching at either side of the Cape of Good Hope, according to the season, and afterwards at Ascension, you will make the best of your way to Spithead, and report your arrival to our Secretary.
