The illusions of imperialism have been made clearer than ever by the course of modern history. Attempts to destroy a nationality by overthrowing its government, proscribing its language, and maltreating its citizens, are never successful. The experiment has been tried with great thoroughness in Poland; and the Poles are now more of a nation than they were under the oppressive feudal system which existed before the partitions. Our own empire would be a ludicrous failure if it were any part of our ambition to Anglicise other races. The only English parts of the empire were waste lands which we have peopled with our own emigrants. We hauled down the French flag in Canada, with the result that Eastern Canada is now the only flourishing French colony, and the only part of the world where the French race increases rapidly. We have helped the Dutch to multiply with almost equal rapidity in South Africa. We have added several millions to the native population of Egypt, and over a hundred millions to the population of India. Similarly, the Americans have made Cuba for the first time a really Spanish island, by driving out its incompetent Spanish governors and so attracting immigrants from Spain. On the whole, in imperialism nothing fails like success. If the conqueror oppresses his subjects, they will become fanatical patriots, and sooner or later have their revenge; if he treats them well, and 'governs them for their good,' they will multiply faster than their rulers, till they claim their independence. The Englishman now says, 'I am quite content to have it so'; but that is not the old imperialism. The notion that frequent war is a healthy tonic for a nation is scarcely tenable. Its dysgenic effect, by eliminating the strongest and healthiest of the population, while leaving the weaklings at home to be the fathers of the next generation, is no new discovery. It has been supported by a succession of men, such as Tenon, Dufau, Foissac, de Lapouge, and Richet in France; Tiedemann and Seeck in Germany; Guerrini in Italy; Kellogg and Starr Jordan in America. The case is indeed overwhelming. The lives destroyed in war are nearly all males, thus disturbing the sex equilibrium of the population; they are in the prime of life, at the age of greatest fecundity; and they are picked from a list out of which from 20 to 30 per cent. have been rejected for physical unfitness. It seems to be proved that the children born in France during the Napoleonic wars were poor and undersized--30 millimetres below the normal height. War combined with religious celibacy to ruin Spain. 'Castile makes men and wastes them,' said a Spanish writer. 'This sublime and terrible phrase sums up the whole of Spanish history.' Schiller was right; 'Immer der Krieg verschlingt die besten.' We in England have suffered from this drain in the past; we shall suffer much more in the next generation.
