In 1801, the boatswain of the NATURALISTE found this plate half buried in sand, lying near an oaken post to which it had been nailed. Captain Hamelin, with rare good taste, had a new post made, and the plate erected in the old spot. Another outward bound ship, the MAURITIUS, touched on the west coast in 1618, and discovered and named the Willems River, near the Northwest Cape, probably the present Ashburton. The LEEUWIN (Lioness), visited the west coast in 1622, and the well-known reef of Houtman's Abrolhos was so-called after Frederick Houtman, a Dutch navigator of distinction who, however, never personally visited Australian shores. The next navigator to the South Land met with an untimely end. In the year 1623, Governor Coen dispatched two yachts, the PERA and the ARNHEM, on a voyage of discovery. Landing on the coast of New Guinea, Captain Jan Carstens, of the ARNHEM, and eight of his crew were murdered by the natives, but the vessels proceeded, and touched upon the north coast of New Holland, west of the Gulf of Carpentaria, still known as Arnhem's Land. A river, the Spult, is here laid down in the old charts, in the vicinity of the present Liverpool River, and there is also another opening marked the "Speult," on the eastern side of the Gulf, since determined to be the Endeavour Strait of Captain Cook, At Arnhem's Land the yachts parted, the Pera continuing the voyage alone. Crossing the head of the Gulf she followed the course of the DUYFHEN, and passing Cape Keer-Weer, made as far south as 17 degrees, where the Staaten River is laid down. Their report was also unfavourable, and is summed up in the official dispatches of the company, thus:--"In this discovery were found everywhere shallow waters and barren coasts, islands altogether thinly peopled by divers cruel, poor, and brutal nations, and of very little use to the Dutch East India Company." Pera Head, in the Gulf, is another memorial of this voyage. Now came the turn of the south coast of New Holland. In 1627, Captain Pieter Nuyts, in his ship the GULDE ZEEPARD, accidentally touched on the south coast. He followed it along for seven or eight hundred miles, and bestowed on it the name of Pieter Nuyts' Land. The VIANEN sighted the west coast in 1628, and kept in sight of it for some two hundred miles, reporting "a foul and barren shore, green fields; and very wild, black, barbarous inhabitants."
