In the colonies the preoccupation of thought and energy has with equal reason been as complete. It is scarce fifty years since the Canadian provinces obtained local self-government. The last half century has witnessed the growth of a most complete system of municipal and provincial institutions, crowned by a great act of constructive statesmanship in Confederation. The organization of half a continent on material lines has kept pace with each step in political construction. Railroads, canals, telegraphs, postal facilities, steamboat communication, all the machinery of modern civilization, have been widely applied to an immense area. In Australia movement has been even more rapid and engrossing. Melbourne has changed in fifty years from a village of a thousand inhabitants to a city of 500,000. Australian commerce, in its infancy when the Queen came to the throne, now equals that of the United Kingdom at the same date. New Zealand, then the home of mere savages, has already a British population which exports annually £10,000,000 worth of the products of civilized labour. In South Africa half a continent is being organized under conditions of extreme difficulty. In the rush of progress so swift as this, the mass of men are conscious chiefly of the work immediately before them. But as this work grows under their hands, the vast external interests are created, and the wide external connections grow up, which compel attention to the larger problems which they involve. {25} The local politician, as provinces consolidate, is, by a process of natural compulsion, changed into the statesman with a national and international range of political vision. It seems almost superfluous to point out that in striving for closer consolidation British people would be following strictly along the lines of the most striking national movements of modern times. They would be merely keeping abreast of the spirit of the age. For the idea of national unity the people of the United States twenty-five years ago made sacrifices of life and money without a parallel in modern history. No one now doubts that the end justified the enormous expenditure of national force. 'The Union must be preserved' was the pregnant sentence into which Lincoln condensed the national duty of the moment, and to maintain this principle he was able to concentrate the national energy for a supreme effort. The strong man who saved the great republic from disruption takes his place, without a question, among the benefactors of mankind.
