now grown into a tree which effectually conceals it from 

 view. The navigation channel lies in the wider portion of 

 the stream between this rock and the left bank. Within the 

 area of the reserve, close to the water's edge and right 

 -opposite to the rock in the river, a group of several other 

 large masses of the same material emerges from the ground 

 and, I understand, that a ridge of granite connects the lat- 

 ter with the former, rendering the intervening channel too 

 shallow for navigation except for small boats. Along the 

 adjacent river margin, and for some distance lower down, 

 willows have been planted at the water's edge and have 

 grown luxuriantly. About 200 yards below the reserve is a 

 small island between which and the right bank is a narrow 

 •channel. This island, like the adjacent bank, is thickly 

 overgrown with closely-planted willows. 



Both the isolated rock in the river and the neighbour- 

 ing group on the bank are portions of a long line of granite 

 outcrop running, approximately, from west-north-west to east- 

 south-east. Other portions of the same outcrop can be seen 

 on the farther side of the river and in the opposite direction 

 on the solid ground beyond the swamp that is being reclaimed. 

 The line of outcrop extends much farther in either direction. 



Within a few feet of the river the natural surfaee of 

 the ground rises, with a gentle incline of about 1 in 10, 

 away from, and in a direction at right angles to, the river 

 bank, and, as one stands with the back to the latter looking 

 up this incline, the ground surface shows a similar gentle 

 slope to the right and left. Thus the section parallel to 

 the river and across the incline, which was that actually made 

 in the removal of the soil, shows a gentle and even convexity 

 (plates ii., iii., and iv.). 



In former days a group of the indigenous Cypress Pine 

 <(Callitris Sp.) grew upon the slope, but they have now all 

 disappeared from that immediate locality, though a few trees 

 still remain in the neighbourhood. 



Recourse was had to this bank to provide material for 

 the embankment, and the removal began at its lowest part 

 within a few feet of the stream, and, of course, as the cut- 

 ting advanced away from the river the deeper became the 

 face of the exposed section. 



The geological characters of this section will be described 

 directly. 



Early in April, 1911, and soon after this work had 

 begun, there appeared in the daily Press notices that skeletons, 

 presumably those of aboriginals, were being exposed in the 

 course of the removal of the earth, and, on the 5th of the 

 month, intimation was received at the Museum from Mr. A.
