342 THE DISCOVERY OF AUSTRALIA 



Campbell The story turns to notice British plans. In 1744-1748 a 

 commercial wr * ter named Campbell brought out a new edition of 

 enterprise, the Collection of voyages that had been published by 

 Harris in 1705. Campbell's plan was to tell the story 

 in such a way that it would point a moral. He printed 

 the original narratives, and he added prefaces, introduc- 

 tions, and remarks which explained the lessons which 

 Englishmen should learn from their reading. The chief 

 lesson was the importance of commerce. His work was 

 dedicated to the " Merchants of Great Britain," and he 

 sought to prove that " to commerce we owe our wealth." 

 It was to commerce also that we owe our strength ; for 

 " whoever is master at sea must be master at land likewise." 

 And it is in order to show one way by which commercial 

 wealth and strength may grow, that he prints and explains 

 especially in the narratives of travel in the South Sea. Very interesting 

 the South O ug are j-^g geographical conclusions which he founds 

 upon them. " It is most evident from Tasman's voyages," 

 he writes " that New Guinea, Carpentaria (i.e. Cape York 

 peninsula), New Holland, Van Diemen Land, and the 

 country discovered by Quiros make all one continent, 

 from which New Zealand seems to be separated by a strait, 

 and perhaps is part of another continent." The outlines 

 of the continent which centres in New Holland are well 

 known. The only " Terra Australis " that now remains 

 " incognita " is the continent which, as we must assume, 

 lies between New Zealand and America : a continent 

 which probably includes New Zealand itself, and the 

 various promontories that had been seen by Quiros, Le 

 Maire, Davis, Roggeveen, and others. 



Quiros was Campbell was deeply interested in this Terra Australis 

 Incognita. He quoted with acceptance Roggeveen's argu- 

 ments, mainly taken from Quiros, to prove its existence 

 and its richness. British merchants were always grumbling 

 about the decay of the old trades. They should find 

 out new trades. The war gave an excellent opportunity 

 to exploit the South Sea. Anson had sailed on his famous 

 voyage in 1741, and returned in the year of the publication 

 of Campbell's book. There was no reason either to be
