Leaving Bowman's islands, and continuing their course towards the N.W. they came next morning in sight of two islands, which they took to be _Coccos_ and _Traitor's_ islands,[7] so called by Schouten, who discovered them. The island of Coccos, at a distance, for Roggewein would not stop to examine it, seemed very high land, and about eight leagues in circuit. The other seemed much lower, composed of a red soil, and destitute of trees. They soon after saw two other islands of large extent, one of which they named _Tienhoven_,[8] and the other _Groninguen_; which last many of their officers were of opinion was no island, but the _great southern continent_ they were sent out to discover. The island of _Tienhoven_ appeared a rich and beautiful country, moderately high, its meadows or low lands, by the sea, exceedingly green, and the interior well provided with trees. They coasted along this island for a whole day without reaching its extremity, yet noticed that it extended semi-circularly towards the island of Groninguen, so that those which they took for islands might be contiguous lands, and both of them parts of the _Terra Australis incognita_. [Footnote 7: There must be here an enormous error in the text; Coccos and Traitor's islands are almost directly west from Recreation island, and the northermost of the Society islands, supposed to be the Bowman's islands of the text, and not less than 23°10' farther west than these last, or 463 marine leagues, which could not well be run in less than a week or ten days.--E.] [Footnote 8: These were probably the _Fee-jee_, or Bligh's islands, in lat. 17° 20' S. long. 181° 30' W. but the narrative is too incomplete to ascertain this and many other points with any tolerable certainty.--E.]
