On May 31, 1910, the Union of South Africa became an accomplished fact. The four provinces of Cape Colony, Natal, the Orange Free State (which bears again its old time name) and the Transvaal are henceforth joined, one might almost say amalgamated, under a single government. They will bear to the central government of the British empire the same relation as the other self-governing colonies—Canada, Newfoundland, Australia and New Zealand. The Empire will thus assume the appearance of a central nucleus with four outlying parts corresponding to geographical and racial divisions, and forming in all a ground plan that seems to invite a renewal of the efforts of the Imperial Federationist. To the scientific student of government the Union of South Africa is chiefly of interest for the sharp contrast it offers to the federal structure of the American, Canadian and other systems of similar historical ground. It represents a reversion from the idea of State rights, and balanced indestructible powers and an attempt at organic union by which the constituent parts are to be more and more merged in the consolidated political unit which they combine to form.
