Note (return) — LECTURE IV

I have said that among the causes which have kept the aborigines of Australia at a very low level of savagery must be reckoned the desert nature of a great part of the country. Now it is the interior of the continent which is the most arid, waste, and barren. The coasts are comparatively fertile, for they are watered by showers condensed from an atmosphere which is charged with moisture by the neighbouring sea; and this condensation is greatly facilitated in the south-eastern and eastern parts of the continent by a high range of mountains which here skirts the coast for a long distance, attracting the moisture from the ocean and precipitating it in the form of snow and rain. Thus the vegetation and hence the supply of food both animal and vegetable in these well-watered portions of the continent are varied and plentiful. In striking contrast with the fertility and abundance of these favoured regions are the stony plains and bare rocky ranges of the interior, where water is scarce, vegetation scanty, and animal life at certain seasons of the year can only with difficulty be maintained. It would be no wonder if the natives of these arid sun-scorched wildernesses should have lagged behind even their savage brethren of the coasts in respect of material and social progress; and in fact there are many indications that they have done so, in other words, that the aborigines of the more fertile districts near the sea have made a greater advance towards civilisation than the tribes of the desert interior. This is the view of men who have studied the Australian savages most deeply at first hand, and, so far as I can judge of the matter without any such first-hand acquaintance, I entirely agree with their opinion. I have given my reasons elsewhere and shall not repeat them here. All that I wish to impress on you now is that in aboriginal Australia a movement of social and intellectual progress, slow but perceptible, appears to have been setting from the coast inwards, and that, so far as such things can be referred to physical causes, this particular movement in Australia would seem to have been initiated by the sea acting through an abundant rainfall and a consequent abundant supply of food.109
