Whoever, therefore, would increase the division of labor among the people, must, first of all, extend their market; and this is done most efficiently by improving the means of communication. Even in our day, it is over the water-highroads that the heaviest articles are carried with the least expenditure of force;(370) but where civilization is not advanced, these highroads possess still greater advantages, because of their safety, convenience and priority. And here is the explanation of the intimate connection of the beginnings of all civilizations with the existence, near the scene of such beginnings, of good natural water-roads. “Even the wildest inhabitant of the sea coast very soon obtains the idea of distance, which is altogether wanting to the inhabitant of the primeval forest. No sooner does he catch sight of the far-off island than his yearning after the distant assumes a well-defined character. Bits of wood floating past him suggest to his mind the best material to buoy himself up upon the water, and a fish the best form for his craft.” (_Klemm._) Hence the Mediterranean sea, especially the eastern portion, with the various peoples and products of its coasts, with its numerous islands, peninsulas and bays, its easy navigation, but little influenced by the tides or by ocean currents, was the principal seat of ancient civilization.(371) The literal meaning of Attica is coast-land. (_Strabo._) The colonization of a new country is wont, where possible, to begin on the coast, especially on islands near the coast; and to follow the course of rivers into the interior. Even whole continents occupy, for the most part, in the history of the world, the position assigned them by their coast-development.(372) While it is hard to determine whether, in the case of the European continent, its limbs predominate or its trunk, Africa may be said to be a trunk without members. Its islands, most of them insignificant in themselves, are almost entirely cut off from it by ocean currents. This explains why Madagascar had not, by any means, the influence on African civilization which Crete, Sicily and Britain have had on the civilization of Europe. Asia occupies, in this respect, about a middle position between Europe and Africa. The trunk of that continent bears to its members about the proportion of 670,000 to 150,000 square miles. And what is worst of all, the middle of the whole is an almost insurmountable wall between north, south, east and west Asia. Hence the tenacious peculiarity and isolated development of the Chinese, Malayan, Indian and Arabic civilizations; while the three peninsulas of southern Europe, for instance, have affected one another so largely, and in so many different ways.(373) The northern hemisphere compared with the southern, presents a contrast similar to that between Europe and Africa, or of the rich coast-groups of the Atlantic compared with the poor ones of the
