We are thus led to picture the early home of Celtic dialects on territory now falling under French, Dutch and German rule. It is not unlikely that England and Ireland are areas of expansion of this language. Eastward, it is known that the Celtic territory extended at least as far as the Elbe. Beyond, in the same direction, an ever widening wedge of Teutonic area interposed itself between Celts and Slavs. The prehistoric home of the Teutons will be found in the region around the western extremity of the Baltic Sea. It comprised southern Sweden, Jutland, the German Baltic coast to the Oder and the Baltic islands as far as Gothland. The Slav’s original homeland had its site on an imperfectly drained lake-bed extending westward from the middle Dnieper valley to the Niemen and Priepet marshland.

A region of transitional dialects between High and Low German.] From east to west on the Eurasian land mass the three main forms of language occupy strictly geographical settings. Monosyllabic Chinese lies rigid and lifeless within its barriers of high mountains and vast seas. The static condition of Chinese civilization is reflected in the changeless form of its language. A new idea requires a new word and a corresponding symbol. In the wild and wide-stretching steppes of Siberia, communication of thought or feeling is maintained through the medium of agglutinative forms of speech. Grammatically, this marks an improvement over the monosyllabic language. In the case considered here it expresses the restlessness and mobility of steppe life. At the same time inferiority of civilization is revealed by poverty of ideas and consequently of words. In the west, however, whether we consider western Asia or Europe, we deal with the world’s best nursery of civilization. In those regions are found the highly inflected and flexible languages of the Aryan and Semitic families. The grammar of these languages--a mere adaptation to superior requirements of order and method--renders them particularly responsive to the constant improvement in thought which characterizes western countries.
