a [***]. He acquitted himself of the task to
admiration, and has given a very lucid survey of the (accidental)
discoveries made by the Dutch on the west-coast of Australia. In this
chart of 1627 the Land of d'Eendracht takes up a good deal of space. To
the north it is found bounded by the "Willemsrivier", discovered in July
1618 by the ship Mauritius, commanded by Willem Janszoon [****].
According to the chart this "river" is in about 21 deg. 45' S. Lat., but
there are no reliable data concerning this point. If we compare Hessel
Gerritsz's chart with those on which about 1700 the results of Willem De
Vlamingh's expedition of 1696-7 were recorded [*****] we readily come to
the conclusion that the ship Mauritius must have been in the vicinity of
Vlaming Head (N.W. Cape) on the Exmouth Gulf. From Willem Janszoon's
statements it also appears that on this occasion in 22 deg. an "island (was)
discovered, and a landing effected." The island extended N.N.E. and
S.S.W. on the west-side. The land-spit west of Exmouth Gulf may very
possibly have been mistaken for an island. From this point then the
Eendrachtsland of the old Dutch navigators begins to extend southward. To
the question, how far it was held to extend, I answer that in the widest
sense of the term ('t Land van Eendracht or the South-land, it reached as
far as the South-coast, at all events past the Perth of our day) [******].
In a more restricted sense it extended to about 25 deg. S.' Lat. In
the latter sense it included the entrance to Shark Bay, afterwards
entered by Dampier, and Dirk Hartogs island, likewise discovered by Dirk
Hartogs.

[*** It is evident that he did not use all the data then available. Thus,
for instance, he left unused those furnished by the Zeewolf (No. VIII,
pp. 10 ff. below), and those of the ship Leiden (No. XV, p. 49).]

More to southward we find in the chart of 1627 I. d'Edels landt, made in
July 1619 by the ships Dordrecht and Amsterdam, commanded by Frederik De
Houtman and Jacob Dedel [*]. To the north of Dedelsland the coast is
rendered difficult of access by reefs, the so-called (Frederik De)
Houtmans-Abrolhos (now known as the Houtman Rocks), also discovered on
this occasion [**]. To the south, in about 32 deg. S. Lat. [***] Dedelsland
is bounded by the Landt van de
