The forms Pan-Angle governments take are now two. One is the simple unitary form in which the central government is supreme within the sanction of the will of the voters expressed at the polls, any other government being a subordinate, i.e. a municipal government. The other form is not unitary, and the central government is supreme in the exercise of certain authority only, other governments being in all else supreme and autonomous partners. The states of America, for example, and those of Australia are unitary in government. Of the seven Pan-Angle nations, three, Newfoundland, New Zealand, and the British Isles, are unitary, the central government in each being supreme over every part and in every respect. Of the non-unitary governments there are four: the United States, Canada, Australia, and South Africa. By an accident of time and place America was the first to grapple with the problems which called for such a government. Thirteen states independent of each other and of any outside power found themselves in danger from inter-state contentions and external aggressions. Building for their very lives, they devised a form of government which has been called federal. In it each state kept most of its sovereign powers, but delegated certain others of them to a central legislature. The federation of the six Australian states followed much the same lines. In Canada and South Africa the states (in both cases called provinces) have retained less of their local autonomy. {194} The central government in the former may with some legislative difficulty and delay assume any power it desires, while in the latter unrestricted power has been lodged from the beginning in the central government. In neither of these two nations, however, has the central government assumed the exercise of its full possible power. In both it co-exists at present with the provincial governments after a federal manner, obtaining thus the advantages of federation. For comparatively restricted areas within which problems and opinions are tolerably uniform, a unitary government satisfies Pan-Angles. States and provinces are such areas. Newfoundland and New Zealand are at present such areas. In Newfoundland the population is very sparse and the local variations are slight. It will be many years probably before there arises a need and a desire for devolution[194-1] of power from the present legislature. In New Zealand conditions are not so uniform, and although a unitary government seems satisfactory to-day, the time may readily be imagined when a denser population and conflicting interests of different sections of the country may make feasible local legislatures, each, for its allotted tasks, supreme. The only attempt so far towards that end originated outside of New Zealand and was abandoned before being put into practice.[194-2] {195}
