[*** About this latitude, between 32° and 33° S. Lat., also De Houtman and Dedel estimated themselves to be, when they first came upon land. They afterwards ran on on a northerly course.]

So much for the highly interesting chart of Hessel Gerritsz of the year 1627. If we compare with it the revised edition of the 1618 chart, we are struck by the increase of our forefathers' knowledge of the south-west coast. This revised edition gives the entire coast-line down to the islands of St. François and St. Pieter (133° 30' E. Long. Greenwich), still figuring in the maps of our day: the Land of Pieter Nuyts, discovered by the ship het Gulden Zeepaard in 1627 [*].
[* See No. XVIII (p. [51]) below.]
North of Willemsrivier, this so-called 1618 chart has still another addition, viz. G. F. De Witsland, discovered in 1628 by the ship Vianen commanded by G. F. De Witt [*]. In this case, too, it is difficult to determine exactly the longitudes between which the coast-line thus designated is situated. [**] But with great distinctness the chart exhibits the chain of islands of which the Monte Bello and tha Barrow islands are the principal, and besides, certain islands of the Dampier Archipelago, afterwards so called after the celebrated English navigator. I would have these observations looked upon as hints towards the more accurate determination of the site of this De Wit's land, and they may be of the more value since the small scale of the chart renders an exact determination of it exceedingly difficult.

[** See, however, No. [XXI., C.] infra.]
In Gerritsz's chart of 1627, as well as in the so-called 1618 one, we are struck by the fact, that on the west-coast the coast-line shows breaks in various places: De Witt's land is not connected with the coast of Willems-rivier; the coast-line of Eendrachtsland does not run on; there is uncertainty as regards what is now called Shark-bay; the coast facing Houtmans Abrolhos is a conjectural one only; the coast-line facing Tortelduyf is even altogether wanting; Dedelsland and 't Land van de Leeuwin are not marked by unbroken lines. This fragmentary knowledge sufficiently accounts for the fact, that about the middle of the seventeenth century navigators were constantly faced by the problem of the real character of the South-land: was it one vast continent or a complex of islands? And the question would not have been so repeatedly asked, if the line of the west-coast had been more accurately known.
