From this place you are to coast along the west coast of New Guinea, to the furthest discoveries in 17 degrees south latitude, following the coast further, as it may run west or southward. But it is to be feared you will meet in these parts with the south-east trade winds, from which it will be difficult to keep the coast on board, if stretching to the south-east; but, notwithstanding this, endeavour, by all means to proceed, that we may be sure whether this land is divided from the great known south continent or not." Thus it became part of Tasman's duty to explore Torres Straits, then unknown, though possibly suspected to exist. That they had unconsciously been passed through by Torres, in 1606, we have already seen. Tasman, however, failed, as will be presently shewn, in making the desired exploration, and it was not till 1770 that the separation of New Holland from New Guinea was established by Captain Cook. In the remaining portion of his duty, Tasman fully succeeded, viz., in establishing the continuity of the north-west coast of the land designated generally "the great known south continent," as far south as about the twenty-second degree. It is greatly to be regretted that the account of this interesting voyage has not been published. The Burgomaster Witsen, in a work on the migrations of the human race, which appeared in 1705, gives some notes on the inhabitants of New Guinea and New Holland, in which Tasman is quoted among those from whom he gained his information; thus showing that Tasman's narrative was then in existence.
