On 4th September Midshipman Colnett sighted a large island, which was named New Caledonia, the point first seen being called Cape Colnett. An opening in the surrounding reef having been found by the boats, the Resolution worked up to an anchorage and was quickly surrounded by canoes whose occupants were totally unarmed. At first they were shy of coming near, but at length one canoe was persuaded to receive some small presents, and in return gave some fish which "stunk intolerably," but for all that it was received in hopes more satisfactory trading might result. To some who came on board dinner was offered, but they would touch nothing but yams. They appeared to know nothing of dogs, goats, or hogs, but greatly appreciated both red cloth and nails. Cook landed and was well received, and water was pointed out, but it was too inconvenient of access; the land near a village was well cultivated and irrigated, the products being chiefly yams, plantains, and coconuts, the latter were not bearing much fruit.
On 6th September Mr. Wales secured a moderately satisfactory observation of an eclipse of the sun, and was able to fix their position as 20 degrees 17 minutes 39 seconds South, 164 degrees 41 minutes 21 seconds East. On the same day the ship's butcher, Monk, "a man much esteemed in the ship," fell down the forehatch, and died the following day from the injury received. Whilst some of the crew were engaged in watering, a small party went up the hills to view the surrounding country, but as all the natives they met turned back to follow them, Cook remarks, "at last our train was numerous." They were able to see right across the island, and estimated the width to be not more than ten leagues. On returning it was found the clerk had purchased a fish, something like a sun-fish; and as the artist was engaged in drawing and describing it, the cook took the liver and roe for supper in the cabin, with the result that Cook and the Forsters were nearly poisoned, and were only cured by the most careful attention of the surgeon. When the natives saw the fish the next morning they immediately signified it was unfit to eat, but Cook says nothing of the kind had been intimated when it was purchased.
