The need of colonies is often put forward as a real and also a legitimate motive for war. Colonies must be provided, they say, for the overflow of population from the homeland; colonies are the foundation of the trade of nations--trade follows the flag. They think of colonies as the offspring of nations, and nations without colonies seem sterile and destined to extinction. We know that Germany's desire for colonies is one of the causes of the European crisis, and that the colonial question has been a fertile cause of trouble in Europe for many years. And yet we have evidence that in the present economic stage of the world, colonies do not perform to any great extent either of the functions that are claimed for them. Trade does not in general follow the flag; industrial nations do not need colonies either to provide for over-population or for commercial reasons. The acquisition of colonies does not as such benefit the great industrial and financial interests. Why, then, do nations so ardently desire colonies; and why, without colonies, do they feel themselves inferior and at a disadvantage? Why, in a stage of industry, in which it is presumably more to their advantage to conduct aggressive campaigns in countries already densely populated, are nations so willing even to fight to obtain colonies? Powers (75) says that the desire for colonies comes from the idealistic tendencies of nations. This appears to be true. Correspondingly we find that colonies are of more interest to general staffs and admiralties than to captains of industry. Colonies are wanted for military reasons, more than for trade reasons. Colonies are desired as bases of operation in the game of empire building by conquest. There is still another reason. The race for colonies perpetuates an ideal which has grown out of an earlier stage of the life of nations. Colonies were once actually the means of the greatness of nations. The longing for colonial possessions, for the extension of commerce, the great jealousy and apprehension of peoples in regard to their trade routes, and the fear nations have for their commerce, quite out of relation to present needs and conditions, hark back to an old romance of the sea. The waterways of the world, the islands and new continents have a traditional appeal, which comes down to us from the days when the small countries of Europe, one after another--Portugal, Holland, Spain, England--became great in wealth, and grew to be world powers, by their commerce and their colonial possessions. In those days the expansion of nations was not at all due to economic pressure at home. The landowners, the rules, the privileged class in general were interested in colonies, because in that direction stretched the path to fabulous wealth, and because over the seas were the lands of adventure. The seeking of colonies was both the business and the pleasure of the nations. To-day the gaining of colonies may be only a loss to nations economically, but they satisfy
