But ships did not always sight the Australian coast at the same point. Hence it came about that in 1619 J. de Edel "accidentally fell in with" the coast at the back of the Abrolhos. Pieter Nuyts, in 1627, "accidentally discovered" a long reach of the south coast. Similarly, in 1628, the Vianen was "accidentally," as the narrative says, driven on to the north-west coast, and her commander, De Wit, gave his name to about 200 miles of it. In 1629 the Dutch ship Batavia was separated in a storm from a merchant fleet of eleven sail, and ran upon the Abrolhos Reef. The captain, Francis Pelsart, who was lying sick in his cabin at the time of the misadventure, "called up the master and charged him with the loss of the ship, who excused himself by saying he had taken all the care he could; and that having discerned the froth at a distance he asked the steersman what he thought of it, who told him that the sea appeared white by its reflecting the rays of the moon. The captain then asked him what was to be done, and in what part of the world he thought they were. The master replied that God only knew that; and that the ship was on a bank hitherto undiscovered." The story of Pelsart's adventure was recorded, and the part of the coast which he saw was embodied on a globe published in 1700. To the accidental discoveries must be added those made by the Dutch prompted by curiosity as to the possibility of drawing profit from the lands to the south of their great East India possessions. Thus the Dutch yacht Duyfhen, sent in 1605 to examine the Papuan islands, sailed along the southern side of Torres Strait, found Cape York, and believed it to be part of New Guinea. The great discovery voyages of Tasman, 1643 and 1644, were planned in pursuit of the same policy. He was directed to find out what the southern portion of the world was like, "whether it be land or sea, or icebergs, whatever God has ordained to be there." In 1606 the Spaniard, Torres, also probably saw Cape York, and sailed through the strait which bears his name. He had accompanied Quiros across the Pacific, but had separated from his commander at the New Hebrides, and continued his voyage westward, whilst Quiros sailed to South America. It is needless for present purposes to catalogue the various voyages made by the Dutch, or to examine claims which have been preferred on account of other discoveries. It may, however, be observed that there are three well defined periods of Australian maritime discovery, and that they relate to three separate zones of operation. First, there was the period with which the Dutch were chiefly concerned. The west and north-west coasts received the greater part of their attention, though the voyage of Tasman to the island now bearing his name was a variation from their habitual sphere. The visits of the Englishman, Dampier, to Western Australia are comprehended within this period.
