the delta are moreover, either at sea-level or even a trifle 

 below sea-level. Peat beds clipping below the level of low 

 water occur at Fingal Bay near Port Stephens, and similar 

 peat struck at about 80 feet below sea-level at a bore 

 west of Anna Bay, Port Stephens, points to a recent sub- 

 sidence of the coast, a movement which is confirmed by 

 the evidence of the quantities of wood and coarse gravel 

 met with in the Stockton Colliery's pit at about 180 feet 

 below sea-level. 



The following is a table of the sequence of the Hunter 

 River Delta deposits : — 



1. Blown sand and peat together with recent ironstone 



deposits around swamps in the sand dunes. The iron- 

 stone is used as a flux by the Sulphide Corporation 

 Works at Cockle Creek. 



2. Recent flood loams. 



3. Ancient flood loams which at Elderslie, near Branxton, 



contain remains of the large extinct diprotodont 

 marsupial Nototherium. 



J. Raised beaches such as those of Largs, Font Hill, 

 Campbell's Hill, West Maitland Waterworks, Bolwarra, 

 etc. 



5. Old valley deposits like those met with in the Stockton 

 Pit. 



0. High level gravels, like those near Nicholson's, Oak- 

 hampton, West Maitland ; and on the north bank of 

 the Hunter near Roughit to the south-east of Singleton. 



As regards the alluvial deposits of the Hawkesbury Delta 

 these have been classed in the paper above referred to as 

 Pleistocene and recent. 



The Pleistocene comprise (1) the red sandy soils for the 

 most part above the reach of modern floods as shown in a
