Note 224 — Chapter IV · —The Movements Of Peoples In Their Geographical Significance

Entrance into a naturally isolated district, from which subsequent incursions are debarred, gives conditions for divergence and the creation of a new type. On the other hand, where few physical barriers are present to form these natural pockets, the process of assimilation goes on over a wide field. Europe is peculiar among the family of continents for its "much divided" geography, commented upon by Strabo. Hence its islands, peninsulas and mountain-rimmed basins have produced a variegated assemblage of peoples, languages and culture. Only where it runs off into the monotonous immensity of Russia do we find a people who in their physical traits, language, and civilization reflect the uniformity of their environment.224
