The ethnic and political boundaries of Europe to-day are the residuum of countless racial, national, tribal and individual movements reaching back into an unrecorded past. The very names of Turkey, Bulgaria, England, Scotland and France are borrowed from intruding peoples. New England, New France, New Scotland or Nova Scotia and many more on the American continents register the Trans-Atlantic nativity of their first white settlers. The provinces of Galicia in Spain, Lombardy in Italy, Brittany in France, Essex and Sussex in England record in their names streams of humanity diverted from the great currents of the Voelkerwanderung. The Romance group of languages, from Portugal to Roumania, testify to the sweep of expanding Rome, just as the wide distribution of the Aryan linguistic family points to many roads and long migrations from some unplaced birthplace. Names like Cis-Alpine and Trans-Alpine Gaul in the Roman Empire, Trans-Caucasia, Trans-Caspia and Trans-Baikalia in the Russian Empire, the Transvaal and Transkei in South Africa, indicate the direction whence the advancing people have come. [Sidenote: Stratification of races] Ethnology reveals an east and west stratification of linguistic groups in Europe, a north and south stratification of races, and another stratification by altitude, which reappears in all parts of the world, and shows certain invading dominant races occupying the lowlands and other displaced ones the highlands. This definite arrangement points to successive arrivals, a crowding forward, an intrusion of the strong into fertile, accessible valleys and plains, and a dislodgment of the weak into the rough but safe keeping of mountain range or barren peninsula, where they are brought to bay. Ethnic fragments, linguistic survivals, or merely place names, dropped like discarded baggage along the march of a retreating army, bear witness everywhere to tragic recessionals.
