While the flints may exhibit a great variety of coloura and shades, the pre- 
dominant colours range from dark grey to bimish-black, 
The banks of fiints occurrimg at high water mark and accumulated there 
by wave action along this section of the coastline and beyond were the chief source 
of supply for the natives. Other sources appear to haye been the deposits left 
ag remnants of former shorelines now miles inland. A number of these have been 
loeated on the coastal side of the Woakwine Range (e.g. Narrow Neck) and else- 
where, and many others exist without a doubt in the scrub at the foot of the 
Woakwine Range, 
The practical certainty in this district that a bare spot on a hillside will prove 
to be a Windblown area carrying at least some evidences of former native ooeupa- 
tion, such as hearths, flint chippings, ete, coupled with the knowledge that 
conditions ereated by European occupation have favoured wind erosion, makes 
it difficult to believe that all these blown areas existed as such when the white man 
arrived, No doubt this was true of many areas, but it is logical to be doubtful 
of the recent occupation of all of them, especially as active erosion is atill proceed- 
ing and extending the areas. Such instances are the Belt Site, Wk. 5, KR. 5, ete, 
In the Bevilaqnua’s Ford area, wind erosion and sand drift are so active that 
it. is evident that canip sites examined in any one year may well be buried next 
year and others be exposed, It is probable that removal of the surface cover almost 
anywhere in the dune ridges and ranges would expose evidence of former native 
oveupation, particularly in those parts which are situated favourably with respect 
ta shelter, food, and water supply, 
The Belt Site, notable for its richness and variety of artefacts, is an instances 
where active wind erosion is bringing to view parts of a former camp sjte and 
exposing artefacts covered by dune sand. The richness of this and some other 
areas can be attributed partly to the fact that the removal by wind action: of 
the sand has concentrated on a hard floor the whole of the artefacts which pre- 
viously were dispersed in the material vertically above it, This process of concen- 
tration, particularly on sandhill camp sites, of the whole of the material originally 
contained in a dune, on a hard floor and the possible mingling with relics of a 
different. age complicate the study of implements from the point of viaw of 
their age relationships compared with the easier problem involved, for example, 
jn the excavation of stratified levels on the floors of caves and rock shelters. Such 
problems, however, might be simplified if further research confirms the belief 
that the type and degree of alteration of the fiints is a criterion that can be applied 
to the determination of their relative ages. 
PART II. 
Review or THE Foor Suppry or THE Natives. 
Consideration of the various possible sources of food shows clearly that the 
staple diet of the natives must have consisted of marsupials—kangaroos, wallabies, 
possums, wombats, and short-nosed bandicoots ; and of birds such as emus, bustarda 
(Native Turkeys), Native Companions (Australian Cranes), ducks, swans, and 
probably moor-hens and swamp-hens, 
Tn the spring months the eggs of these birds and others would probably have 
formed an important part of the diet. 
In the summer months of the year weather conditions would allow for sequring 
abundant supplies of the large salt-water crayfish, the various shellfish mentioned
