Chamberlain; and his ultimatum of October 1899 precipitated a war which lasted two years and a half, and cost the two republics their independence. The Transvaal was given, and the Orange River Colony was promised, representative government by the Conservatives; but the Liberals, who came into power at the end of 1905, excused them this apprenticeship, and granted them full responsible government in 1906-1907. British colonies have tried a series of useful experiments with the power thus allotted them of managing their own affairs, and have contributed more to the science of politics than all the arm-chair philosophers from Aristotle downwards; and an examination in their results would be a valuable test for aspiring politicians and civil servants. The Canadian provinces, with two exceptions, dispense with a second chamber; elsewhere in the empire, second chambers are universal, but nowhere outside the United Kingdom hereditary. Their members are either nominated by the prime minister for life, as in the Dominion of Canada, or for a term of years, which is fixed at seven in New Zealand; or they are popularly elected, sometimes on a different property qualification from the Lower House, sometimes for a different period, sometimes by a different constituency. In the Commonwealth of Australia they are chosen by each state voting as a whole, and this method, by which a big majority in one locality outweighs several small majorities in others, has sometimes resulted in making the Upper House more radical and socialistic than the Lower; the system of nomination occasionally has in Canada a result equally strange to English ideas, for the present Conservative majority in the House of Commons is confronted with a hostile Liberal majority in the Upper House, placed there by Sir Wilfrid Laurier during his long tenure of office. The most effective provision against deadlocks between the two Houses is one in the constitution of the Australian Commonwealth, by which, if they cannot agree, both are dissolved.
