PRESIDENTIAL ADDRESS. Do 
principally to the east of land blocks, such as Australia, 
New Caledonia, and Western Fiji. Beds of volcanic 
material were formed in the shallow water while in the 
deeper and clearer water wbich lies further from the land, 
beds of “‘soapstone’’ were formed, and with these the 
bedded limestones mentioned above are sandwiched in 
places. 
The movements, which were accompanied and followed | 
by the deposition of bedded “‘soapstone’’ and limestone, 
were of the nature of earth waves whose crests formed 
plateaus with warped margins and whose troughs formed 
zones of subsidence. From the waste of the land crests 
formed thus, the beds under discussion were derived in 
great measure. 
In a later division of the Tertiary period this formation 
of land waves was revived, and asa result of the movement 
the denuded areas were elevated in part and submerged 
alsoin part. The eastern portions of the main island group 
were elevated also. Folding and warping accompanied the 
elevations and depressions. 
The main continental mass, together with the larger 
islands under discussion, has remained in a condition of 
relative stability since that date. Denudation by streams, 
and the formation of continental and island platforms by 
marine action, have been conspicuous around land masses 
such as Australia, New Caledonia, New Zealand, and Fiji. 
The eastern belts, together with the less stable masses, 
such as the Greater Solomons were denuded in great 
measure also. 
At a subsequent date the less stable groups, such as 
those mentioned ina previous paragraph, also Lau (Hastern 
Fiji), the Loyalties (Hastern New Caledonia Group), the 
C- May 3, 1922.
