As we look down on the Cove and its neighbourhood, we must remember that we have in front of us only a small part of the great expanse of landlocked anchorage available in the harbour; there is still room for unlimited growth, though Sydney has already over a third of the total population of New South Wales collected in and around it.
We must now look beyond the actual harbour, and try to place ourselves in the position of the early settlers. We have great distances to cover, since New South Wales is just half as large again as France; we must therefore keep fairly closely to the railway; but we shall not lose much by this as the railway will carry us through all the important districts of the State.
We may travel north, south, or west, and the map can give us some idea of the character of the country through which we shall pass. 12 Sydney lies near the middle of a long strip of coastland, shut in on its western side by the steep edge of a great plateau. In the neighbourhood of Sydney this edge goes by the name of the Blue Mountains. Here the barrier is about forty miles inland; further north, in the valleys of the Hunter and Hawkesbury rivers, the lowland widens out to nearly a hundred miles; while in some parts of the south the highlands come right down to the sea. This narrow strip was the original New South Wales.

We can travel now by railway along the coast strip to Newcastle, 13 then up the valley of the Hunter, and finally climb the Liverpool Range on to the plateau beyond. But the journey was far from easy for the early settlers. In fact, until 1820, when a stock route was discovered from Sydney to Newcastle, the only intercourse with the north was by sea, and Newcastle grew up almost as a separate colony in consequence. The valleys of the Hunter and other rivers gave a natural direction to early settlement, since in their lower courses they flow through wide alluvial flats which are very fertile and easy to cultivate. But they are subject sometimes to devastating floods, as the settlers found to their cost, while the heavy summer rainfall is not well suited to certain of our crops, such as wheat. So in the early days the colony was often in difficulty as to its main food supply.
