Her language has developed a literary standard to which have been approximated the Flemish dialects of a people struggling {52} for recognition, but unlikely to seek union with Holland because of religious divergence. This nevertheless increases the strength of the Dutch tradition, while the growth of German industry has meant almost as much for both Rotterdam and Amsterdam as it has for Antwerp. Further, the provisioning of the big centres of industry has given Holland new commercial opportunities, and she is thus in a position to play her part in relation to her big German and English neighbours, while nevertheless maintaining her own individuality, and, indeed, making that individuality rather a difficulty in connexion with the complex international problem of Antwerp and the Scheldt. That problem, being one of economics rather than of peoples, need not be discussed here beyond an indication of the extremely international development of that premier outlet for the European plain prior to 1914. Standardized German has not ousted old forms of speech in the rural parts of the north-west German coasts, and there has been a tendency to give Frisian literary expression in the nineteenth century, but this movement, like that in favour of Provençal, has not gone far enough to have economic influence or to bear much upon politics. On the whole, with the growth of systems of education, Frisian has receded, and is now chiefly spoken on the west coast of Holstein and of the part of Slesvig which, by plebiscite, has recently decided to remain German. Denmark at the Baltic entry, and linked to the life of that sea especially by its islands and the important passage of the Sound, makes with Norway and Sweden the Scandinavian sub-group in the Teutonic family of languages, and here nations and languages correspond reasonably closely. Whereas Holstein, at the base of the peninsula of Jutland, became included in the Holy Roman Empire of the Middle Ages, Slesvig remained outside that attempted organization. German speech and thought pervaded South Slesvig as far north as the {53} fjord which has Flensburg at its head, but in spite of political effort, 1864-1914, North Slesvig remained steadily Danish in feeling, and has now been liberated to rejoin the little kingdom. The boundary chosen seems to show a fair-minded interpretation of the recent plebiscite, though there are minorities on both sides of the line. Denmark has a very long story from the days of her prehistoric kitchen-middens onwards, and she owes something to the fact that Jutland was in some sort a north-western terminus of a belt of loess, heath, and sand-hill, stretching westward from the steppe border of South Russia. Along this belt came to her the pre-Bronze Age immigrants distinguished by their 'Beaker pottery', and the amber trade seems to have used a part of this route.
