south-west of "Tasmania, Victoria, and South Australia, and to the 
foundering of the eastern extension of Queensland in late Tertiary times, 
when “nearly the whole of the eastern watershed of the old Divide to 
the east of Cairns was sunk beneath the sea." He recognized that New 
Guinea was a lately folded region, where Cretaceous and even Tertiary 
rocks are highly disturbed, and that even in Australia tectonic movements 
are newer as New Guinea is approached. There is need for “а vastly 
extended series of observations both on land and sea before any satis- 
factory theory can be advanced as to the plan upon which this island- 
continent has been built.” 
Jensen (1911), acknowledging his indebtedness to Professor David's 
teaching and discussions, concluded that the Australian “ continent moved 
in an easterly direction throughout the Palaeozoic, and by the end of the 
He held that the dominant folding-foree came in each period from the 
sea towards the land. 
Professor David (1914) again summarized the geology of Australia, 
and also that of Papua, and drew attention (David, 19144) to the eastward 
movement of the basins of deposition of sediments in New South Wales, 
and of the axes of folding and of plutonic intrusions, in the three main 
Palaeozoic epochs of orogeny recognized by him. 
Morgan (1915) was quite uncertain of the position of the land to 
which New Zealand formed the foreshore or continental shelf in Meso- 
zoic times. As a result of Arber’s declaration concerning the absence of 
Glossopteris from New Zealand he “ regretfully dismissed " the idea that 
| the continent lay to the west and was indeed the margin of Gondwana- 
land, though in Seward's (1914) opinion it was not yet necessary to do so. 
(See footnote, p. 41. 
Andrews (1916), while recognizing the easterly growth of Australia 
from the western gneissic massif (obviously only the eastern extremity 
of a still larger continental area), urged that the successive marginal foldings 
were due to the action of centrifugally (not centripetally) directed forces. 
His view is thus more or less in accordance with Suess's conception of the
