But these figures are hardly scientific. Climatic and other considerations will prevent Canada from reaching quite the same degree of greatness as the United States. British South Africa could "hold" 100,000,000 people, but it could not support them on present appearances. The possibilities of Australian settlement are difficult to be exaggerated in view of the steady dwindling of the "desert" area in the light of recent research and exploration, and of the fact that all her area is blessed with a genial climate. New Zealand, to keep 40,000,000 people, would need, however, to have a density of 400 people per square mile, a density surpassed to-day in Belgium and Holland but not reached by Great Britain. A fairly conservative estimate of the possibilities of the British Empire would allow it for the future a white population of 200,000,000, of whom at least half would be grouped near the shores of the Pacific. Presuming a British Imperial Federation on Sir Joseph Ward's lines with such a population, and the mastery of the Pacific would be settled. But that is for the future, the far future. Sir Joseph Ward, in the event, was not able to carry the Imperial Conference with him, the majority of the delegates considering that the time had not yet come for the organisation of an Imperial Federal system. But it is possible that with the passing of time and the growth of the population of the Dominions overseas, some such system may evolve: and a British Empire Parliament may sit one day at Westminster, at Vancouver or at Sydney. Certainly the likelihood is that the numerical balance of the British race will shift one day from the Atlantic to the Pacific. Following Australia's example, New Zealand has adopted a system of universal training for military service, but there are indications that she will not enforce it quite so rigorously as her neighbour. In the matter of naval defence, at the Conference of 1909 the New Zealand attitude was thus defined by her Prime Minister:-- "I favour one great Imperial Navy with all the Overseas Dominions contributing, either in ships or money, and with naval stations at the self-governing Dominions supplied with ships by and under the control of the Admiralty. I, however, realise the difficulties, and recognise that Australia and Canada in this important matter are doing that which their respective Governments consider to be best; but the fact remains that the alterations that will be brought about upon the establishment of an Australian unit will alter the present position with New Zealand.
