Sydney cockle ( Area trapezia), also occurring in con- 
siderable quantities. 
There appeared to be nothing startling in the way 
of flaked stones, or pieces of bone, but the charcoal of 
former fires is still heavily mixed with the sand on the 
cave floor. 
The camping caves of Moreton Bay which I have in 
mind are situated on Point Lookout, Stradbroke Island. 
They, too, are weathered out of, in this case, rhyolitic 
cliffs, by the action of the sea and wind, and have been in 
use at a much more recent date than those of Port 
Jackson. 
They were occupied by members of the Noonukul 
tribe, and one can still find countless numbers of fish 
scales and fish bones mixed with the sand and ash on 
their floors. Amongst the debris also are pieces of turtle 
bone and shell, kangaroo bones and the shells of the 
eugarie ( Donax delt aides ). 
All these remains are buried beneath about one foot 
of sand, and amongst them I was lucky enough to collect 
two very interesting articles. 
(1) A eugarie shell spoke shave, used for the pur- 
pose of scraping down boomerangs and spears to the re- 
quired shape. The shell has a hole drilled through the 
centre, and was held with the concave side to the palm of 
the hand, when in use. 
(2) An oval breast ornament of mother of pearl 
which, when in use, was lmng from the neck of the in- 
dividual by a piece of cord. 
Both these tribes have passed away, but behind them 
they have left a vivid memory in these few remains which 
build in our minds a clear visual picture of their daily 
life before we occupied their land.
